What Is a Soil Profile Evaluation in Sonoma County?

Fri, 06 Feb 2026 20:20:14 GMT

Soil Profile Evaluation: Septic Planning in Sonoma County

A Soil Profile Evaluation is a critical first step in determining whether a property in Sonoma County can support a septic system (OWTS). Replacing the outdated term "pre-perc," this evaluation assesses soil depth and composition to help the Qualified Consultant and County decide on septic system viability and type—not size. It’s distinct from a percolation test and often required for new developments, replacement OWTS, and system expansions.

Key Takeaway

Evaluates soil horizons to determine septic system suitability.
Requires excavation of profile holes in the proposed system area.
Minimum suitable soil depth determines system type and design options.
Mandatory for expanding existing systems or installing new ones.
May require additional wet weather groundwater testing.

Sonoma County requires a soil evaluation before approving an onsite septic system (OWTS). If you have researched septic permitting in the past, you may be familiar with the term “pre-perc.” That term is no longer used by the County of Sonoma. The process is now referred to as a Soil Profile Evaluation and documented in a Soil Profile Evaluation Report.

While the terminology has changed, the purpose of the evaluation has not. A Soil Profile Evaluation documents onsite soil conditions so the County can determine whether a property has septic potential and what type of system may be supported.

This evaluation is often confused with a percolation test. Although both involve soil investigation, they serve different purposes and are not interchangeable.

The County staff members no longer are onsite during these evaluations, so they can be scheduled quickly.

Soil Profile Evaluation vs Percolation Test

Both procedures collect soil related data for septic planning, but they answer different questions.

A percolation test measures how quickly water moves through soil. The test is performed by digging multiple test holes across a parcel and adding water over the course of several hours. The drop in water level is monitored and used to calculate a percolation rate. That rate is a major factor in determining the overall size of a proposed septic system. Percolation testing may be required depending on the project type, site conditions, and County review criteria.

A Soil Profile Evaluation focuses on soil depth and composition. Its purpose is to determine septic system suitability and system type rather than system size. In the case of developed lots with septic suitable soil, the Profile Hole Evaluation results are used to estimate system sizing parameters. The evaluation is performed by a Qualified Consultant and results documented in a Soil Profile Evaluation Report submitted for County review.

How a Soil Profile Evaluation Is Performed

During a Soil Profile Evaluation, a backhoe or excavator is used to dig profile holes in the proposed septic system location and required reserve area. Each profile hole is excavated to allow observation of soil conditions from grade downward.

As each hole is excavated, soil depths and compositions are logged throughout the total depth of the excavation. The consultant documents changes in soil layers, referred to as horizons. Each horizon is measured and described based on observed soil characteristics.

These observations determine whether a site has septic potential and, if so, what types of septic systems the soil may support.

Soil Depth and Septic Potential

A minimum depth of suitable soil is required for a property to have septic potential. When only minimal suitable soil is present, system options may be limited and above ground systems such as mounds or at-grade systems with pretreatment may be required.

Greater depths of suitable soil allow for additional system options and more flexibility in design. Deeper suitable soils generally make it easier to design less expensive system types.

Expanding an Existing Septic System

A Soil Profile Evaluation may also be required when expanding an existing septic system to accommodate additional bedrooms or an accessory dwelling unit, particularly if no prior evaluation has been completed for the property.

Expanding older gravity trench based septic systems can be more challenging than designing a new system. Existing systems must meet current County soil depth criteria below the dispersal area, which often requires greater verified soil depth than was required at the time of original installation.

Groundwater Considerations

Mottling is a characteristic looked for in soils which can indicate potential seasonally high groundwater levels. Properties require additional wet weather groundwater determination testing when developing or expanding a septic system that proposed to use soils where mottling was observed. In some rare case additional testing is needed on flat sites with soils that don’t lend themselves to mottling. Groundwater conditions can affect system design and approval and are evaluated as part of the overall septic review process when required.

Responding to Landslides: How BC Engineering Group Restores Stability and Peace of Mind

Fri, 21 Nov 2025 19:30:02 GMT

How Engineers Restore Hillside Stability After Landslides

Landslides occur when soil and rock move downhill, often triggered by unstable or saturated ground conditions. They can cause significant damage to property and pose safety risks to communities. Common causes include winter storms, earthquakes, poor drainage, or improperly designed grading. In this blog, BC Engineering Group will highlight the main strategies used to rebuild and restore stability after a landslide has occurred, as well as proactive measures to help mitigate and reduce the risk of future events.

BC Engineering Group Can Help Every Step of the Way

At BC Engineering Group, we specialize in providing civil engineering solutions after a landslide has occurred. Our goal is to help assess the damage, stabilize the site, and restore long-term safety and function. Our team designs grading and drainage plans that incorporate topographic mapping and geotechnical specifications to develop site-specific landslide restoration plans and use them to submit for and obtain permits. Some of the engineered solutions typically found on a grading plan include:

Slope Stabilization

Grading and compaction of existing slopes to reduce the steepness followed by re-compaction of unstable soils to eliminate looseness and improve stability.
Grading is the process of reshaping the land to achieve a desired slope angle or elevation. A gentler slope is less likely to experience soil slippage.
Compaction improves the internal strength of the soil by removing air pockets and voids for water.
Keying and benching are widely used engineering methods for excavation and slope stabilization.
Keying involves cutting a notch or “key” at the base of a slope or retaining wall to help anchor the structure and prevent sliding.
Benching is the practice of excavating in a series of stepped levels (benches) on a slope to reduce soil pressure, improve stability, and provide safer access for construction.
Soil nailing and anchoring, geo grids, and retaining walls to reinforce slopes.
Soil nailing and anchoring involve drilling nails or anchors into the ground to reinforce the soil mass itself (nails) or retaining walls (anchors).
Geogrids are strong, flexible polymer grids that reinforce soil by distributing loads and increasing shear strength. Geo grids are placed horizontally between layers of compacted soil.
Retaining walls retain soil and resist further movement.
If necessary, BC Engineering Group can assess whether a retaining wall is required and coordinate with a structural engineer to help design one for the project.

Surface and Subsurface Drainage

Strict control of surface runoff is essential to ensure the long-term stability and effectiveness of any hillside repair. Proper drainage management prevents erosion, reduces soil saturation, and minimizes the risk of future slope failure.
Culverts and swales are used for surface diversion and redirection of runoff away from slopes.
Subdrain systems like interceptor drains or perforated pipe systems can lower groundwater levels and reduce water pressure.
Drainage systems are frequently incorporated into other repair options including those listed above.

Vegetation and Erosion Control

Erosion and sediment control measures are critical to protect a hillside during landslide remediation, prior to revegetation and stabilization. Some of the common erosion control methods used include hydroseeding and deep-rooted vegetation.
Hydroseeding is a mix of grass or native plant seeds, mulch, fertilizer, water and sometimes tackifiers, that is sprayed out of a high-pressure hose to provide immediate soil coverage and rapid vegetation establishment.
Deep rooted vegetation uses deep rooted plant species, such as native grasses, shrubs, and trees to physically reinforce the soil with their roots, once established.

Mitigate the Risk of Landslides Before they Happen

Landslides can be stressful and dangerous, posing significant risks to property and safety. When developing on a piece of land, or wanting to be proactive at your home base, thoughtful site development can include grading plans and special foundation installation. At BC Engineering Group, strategic infrastructure placement for roads, utilities, and retaining walls are given as much importance as the design and construction, to ensure they are placed on stable slopes. BC Engineering Group specializes in designing efficient surface and subsurface drainage systems to help reduce groundwater pressure and provide erosion prevention. All these solutions help reduce the risk of a landslide before it happens.

Navigating 401, 404, and 1600 Permits: Understanding Waterway Regulations in California

Fri, 07 Nov 2025 21:30:00 GMT

Understanding 401, 404, and 1600 Permits for Work Near Waterways and Waterbodies

Whether you are a homeowner improving a property, a vineyard operator expanding acreage, or a developer planning a larger site, any work near creeks, waterbodies, or drainage channels can trigger environmental permitting requirements. In California, three of the most common are the 401 Water Quality Certification, the 404 Dredge and Fill Permit, and the 1600 Lake and Streambed Alteration Agreement. Understanding what each one covers can help you plan projects more effectively, avoid violations, and keep schedules on track. Navigating these permits can be overwhelming so planning ahead and consulting a design professional can drastically help streamline the process.

The Section 401 Water Quality Certification is issued by the California Regional Water Quality Control Board (RWQCB). It ensures that a project will not degrade the State’s water quality. You will need this permit whenever a project involves discharging fill or dredged material into or out of “waters of the state”, which include streams, ponds, and other features connected to surface water. Common examples include:

Installing a culvert or driveway crossing over a drainage swale or seasonal creek.
Filling or grading low-lying areas that pond water after storms.
Building storm drain outfalls or energy dissipators that release runoff into a creek.
Expanding a vineyard or agricultural operation into an area with a seasonal ponding of water.

The RWQCB may issue a General Order for smaller, low-impact activities that are similar in nature, or an Individual Order for more complex projects. Early coordination and clear site mapping can greatly simplify the process.

The Section 404 Permit is issued by the U.S. Army Corps of Engineers under the federal Clean Water Act. It regulates the placement of fill or dredged material into or out of “waters of the United States”. This includes wetlands and navigable rivers, streams, and even some seasonal drainages that have a connection to downstream waters.

For many small projects, the idea of needing a federal permit can sound intimidating, but the process is often straightforward. The Army Corps has developed Nationwide Permits for activities with minimal environmental impacts. These cover a wide range of common construction projects, including:

Culvert installation or replacement for driveways or road crossings.
Utility line trenching that crosses a stream.
Maintenance dredging or clearing of sediment from ponds.
Bank stabilization or erosion protection using rock riprap.
Installation of small docks or piers.
Construction of stormwater detention or treatment basins.

Most Nationwide Permits require submittal of project plans, location maps, and a short description of the work. Larger or more complex projects that exceed the thresholds for a Nationwide Permit require an Individual Permit, which includes more detailed analysis and public notice.

In practice, many projects that need a 404 permit will also need a 401 certification from the RWQCB, since both agencies regulate similar types of discharges but under different authorities. Coordinating these reviews together can save significant time.

The 1600 Lake and Streambed Alteration Agreement (LSAA) is issued by the California Department of Fish and Wildlife (CDFW). It is required whenever a project will alter the bed, bank, or channel of a river, stream, or lake, or divert or obstruct the natural flow. This permit is focused on protecting fish, wildlife, and riparian habitat rather than strictly water quality. You may need a 1600 Agreement for activities such as:

Replacing or upsizing a culvert.
Stabilizing a stream bank with rock or vegetation.
Removing vegetation or sediment within a channel.
Constructing a bridge, utility crossing, or irrigation diversion.
Repairing erosion or storm damage along a creek.

CDFW’s process often includes site review, evaluation of potential habitat impacts, and development of mitigation measures such as planting native vegetation or restoring disturbed areas after construction. Even seemingly small maintenance work, such as clearing debris from a culvert or grading within a defined channel, can trigger a 1600 requirement.

For developers, these agreements are an important part of larger project approvals, particularly when storm drain outfalls, detention basins, or stream crossings are involved.

While all of these permits can seem complex, they exist to protect California’s waterways and ecosystems from unintentional harm. The best way to simplify the process is to start early. Determining whether your project involves jurisdictional waters can prevent costly delays later. Attempting work in or near waterways without the required approvals can lead to enforcement actions, fines, and restoration orders.

At BC Engineering Group, we assist clients through every step of this process, from identifying jurisdictional waters to preparing permit applications and coordinating with regulatory agencies. Our experience with local and state permitting helps ensure that projects move forward efficiently while maintaining compliance with environmental regulations and protecting California’s vital water resources.

Grading Violations: What You Need to Know and How to Avoid Them

Thu, 23 Oct 2025 20:15:00 GMT

How to Avoid Grading Violations in Santa Rosa & Sonoma County

Grading is one of the most important steps in preparing a site for development, yet it is also one of the easiest to overlook. Whether building a home, planting a vineyard, or starting a commercial project, how the ground is shaped will determine drainage patterns, slope stability, and long-term site performance. In Sonoma County, grading is tightly regulated to protect public safety, water quality, and the environment. When grading is done without proper authorization, the result is frequently a violation that can lead to fines, project delays, or even long-term restrictions on property use.

Sonoma County’s grading regulations apply broadly to earthwork, drainage changes, and slope modifications, and are meant to prevent erosion, sedimentation, and flooding. Agricultural projects face additional oversight under the Vineyard and Orchard Erosion Control Ordinance, known as VESCO, which sets specific standards for vineyard and orchard development to protect soil and watershed health. Knowing when a grading permit is required is the first step in preventing violations. Generally, a permit is required for any project moving a total of fifty cubic yards or more (which is often less than one might think), near a natural water feature, or on unstable sites. Best Management Practices (BMPs), such as straw wattles and sediment bags, should always be included in any grading project.

If grading is performed without a permit, applicants must not only seek approval retroactively but also provide detailed plans documenting conditions before and after the violation, as well as proposed corrective work. Enforcement measures can escalate from administrative notices to daily fines, and in cases where violations are not corrected, the City or County may record a notice on the property title, complicating resale or financing. The consequences of grading violations extend beyond financial penalties. Improper grading can destabilize slopes, redirect stormwater onto neighboring properties, or damage creeks and wetlands. Property owners may be required to remove fill, restore natural drainage patterns, and replant vegetation — often at significant expense.

Avoiding violations is beneficial for all parties and requires careful planning and early engagement with local agencies. Before moving soil, property owners should confirm whether a grading permit is required, which depends on the scope of work, site sensitivity, and proximity to waterways or steep slopes. Thoughtful design that incorporates erosion control measures and protects natural drainage can prevent issues both during and after construction.

At BC Engineering Group, we help clients navigate the complex regulatory landscape of Sonoma County and its cities. Our team is experienced in preparing grading plans, coordinating with planning and code enforcement staff, and assisting with remediation when unpermitted work has already occurred. By addressing grading requirements proactively, projects can move forward smoothly while protecting both the land and the property owner’s investment.

Fire Sprinklers: Knowing the Requirements for Residential, Commercial, and Industrial Uses

Thu, 02 Oct 2025 17:05:09 GMT

Fire Sprinkler Rules in CA: Residential, Commercial & Industrial Use

When planning a new development, whether residential, commercial, or industrial, fire protection is a critical part of the civil design process. One of the most important and widely applied tools in fire safety is the installation of automatic fire sprinkler systems. While they may appear to be a building or mechanical matter, civil engineers must account for sprinklers early in the planning stage to ensure adequate water supply, infrastructure, and compliance with local regulations.

In California, the California Fire Code (CFC) sets the baseline requirements for fire sprinklers. It outlines automatic sprinkler system requirements for residential, commercial, and industrial uses.

Residential: The California Code for residential requires sprinklers in all new one- and two-family dwellings. Additions or remodels may not require sprinklers unless the scope triggers compliance, but local ordinances may be stricter.

Commercial: Group A (assembly), E (educational), I (institutional), and certain other occupancies are generally required to have sprinklers. Thresholds for size, height, or occupant load can trigger requirements.

Industrial & Storage: High-piled storage, hazardous materials, or Group S occupancies often require sprinklers depending on use and square footage.

Local municipalities in California sometimes adopt stricter fire sprinkler requirements. For example, in the City of Healdsburg, amendments to CFC Section 903 extend sprinkler requirements to all Group S occupancies, meaning warehouses and storage buildings, including self-storage facilities, must provide sprinklers even when the base code may not require them.

From a civil engineering perspective, sprinkler requirements tie directly into site design. A project’s water system must deliver both domestic and fire flows, which may require on-site water storage tanks, booster pumps and fire hydrants, verification of adequate pressure, and coordination with fire departments for emergency access. Failure to plan for these requirements early can lead to costly redesigns and utility upgrades, as well as permitting delays.

At BC Engineering Group, we regularly coordinate with local fire marshals and water districts in California and beyond to ensure projects meet fire protection requirements. Our team understands how to integrate these systems into site design efficiently, balancing safety with constructability and cost.

Protect Your Land from Streambank Erosion Damage

Wed, 03 Sep 2025 17:00:02 GMT

How to Spot and Fix Streambank Erosion Legally

Streambank erosion occurs when the edges of stream banks wear away over time. Streambank erosion can accelerate when winter storms dump large amounts of rainfall, causing streams, creeks, and rivers to swell in size. The forces of these large volumes of water are no match for saturated soils that are sitting on the edge of the waterways. This rush of water puts pressure on the saturated soil along the banks, causing chunks to break off and wash downstream. Once a stream bank begins to erode and lose vegetation, such as trees and shrubs, the loss of soil can accelerate very quickly. The land becomes more vulnerable when the root systems have been washed away. In this blog BC Engineering Group will break down why streambank erosion can be bad and how it can be addressed legally and effectively.

Why is Streambank Erosion Bad?

As a property owner, stream erosion can be a serious and costly problem. Eroding banks can eat away at properties and leave behind voids or pits when the water flow subsides. If left untreated, buildings, vineyards, or other investments can be swept away with the soil, causing financial damage and the loss of land. Streambank erosion can also negatively affect the environment by introducing sediments and debris into waterways, which can damage aquatic habitats and raise the risk of downstream flooding.

Can Streambank Erosion Be Fixed?

Yes— Erosion of stream, creek, and riverbanks can be stopped, repaired, or mitigated with conventional earthwork and construction practices. Some of the most effective solutions include stabilizing the bank and drainage diversion. Stabilizing the banks often involves installing natural armoring (such as logs, rocks, or soil bags), retaining walls, or other forms of in-channel revetment to physically protect the soil from water forces. Drainage diversion redirects surface water and can reduce saturated soil conditions.

Fixing It Right, and Legally!

Permitting can be a lengthy and complex process due to streambank restoration being heavily regulated. That’s because creeks, rivers, and the ecosystems they support are protected at the local, state, and federal levels. However, in critical situations, most agencies can allow for emergency permitting options.

To avoid potentially major legal issues, any restoration of erosion in watercourses must involve the agencies with jurisdiction of the elements affected. These agencies typically include:

California Department of Fish and Wildlife
United States Army Corps of Engineers
California Regional Water Quality Control Board
Local Permitting Agency (County or City)

Civil Design and Planning for PV Solar Ground-Mounted Arrays

Thu, 19 Jun 2025 19:02:55 GMT

Key Planning Considerations for Ground-Mounted Solar Projects

As renewable energy continues to expand across the landscape, more property owners, developers, and municipalities are looking toward ground-mounted photovoltaic (PV) solar arrays to meet energy demands sustainably. While the focus is often on the panels themselves, the success of any ground-mounted solar project begins much earlier: with the civil design and site planning .

Navigating Regulatory Requirements

Many local regulations treat solar arrays similarly to structures, necessitating adherence to specific construction standards. Solar arrays must maintain defined setbacks from property lines, roads, structures, and protected areas, typically ranging from 10 to 50 feet, depending on the jurisdiction. Additionally, site constraints such as easements, floodplains, and wetlands require careful mapping to prevent conflicts during construction and permitting.

Addressing Stormwater Management

Solar installations can alter natural drainage patterns, making stormwater management a critical component of the design. Implementing low-impact development (LID) practices—such as vegetated swales, infiltration basins, and strategic grading—can effectively manage and treat stormwater on-site. These methods help maintain the site's natural hydrology and reduce runoff, aligning with sustainable development goals.

Evaluating Soil Conditions

Soil conditions significantly influence the type of foundation required for solar panels. Conducting a geotechnical study is often necessary to assess soil properties, including bearing capacity and stability. This evaluation informs the selection of appropriate foundation systems, such as driven piles or ground screws, ensuring structural integrity and longevity of the solar array.

Planning for Maintenance Access

Ground-mounted solar arrays are not "set and forget" installations; they require regular maintenance. Civil engineering plans should incorporate access roads designed to accommodate construction and maintenance vehicles. These roads must feature suitable surfacing and slopes and may need to comply with local fire department requirements for emergency access.

Coordinating with Regulatory Agencies

Projects often necessitate coordination with city, county, and sometimes state agencies. Engaging in early site evaluation and planning can significantly reduce delays in the approval process. At BC Engineering Group, we have extensive experience working with such agencies and are prepared to leverage our expertise to efficiently guide projects through the necessary procedures.

Beyond the Tank: Understanding Septic Inspections for Buyers and Sellers

Tue, 23 Jul 2024 17:39:13 GMT

Ensuring Value: The Significance of Septic Inspections in Real Estate

What is a Septic Inspection

A septic inspection is typically conducted as part of real estate transactions and is utilized to gather an understanding of the overall septic system condition and functionality. The on-site septic system plays a crucial role in the overall functionality of the property, and its ability to consistently serve the home is essential.

Understanding the Inspection Process

As part of our septic inspection process, we will coordinate with a local septic pumping company to pump the septic tanks while onsite during the inspection. BC Engineering Group will handle all of the scheduling related to the inspection to allow for a streamlined process and quick turnaround on the inspection report.

During the septic inspection, our inspector will be on-site alongside the pumpers to initiate the process of exposing the septic tank. Following the uncovering of the tanks, either a hydraulic load test or a pump test will be performed on the septic system. Septic systems vary, with some relying solely on gravity for effluent dispersal, while others utilize pumps for effluent distribution across the dispersal area. Before conducting either of these tests, we will inspect the assumed dispersal area, taking note of soil conditions, vegetation, and any observed soil saturation.

Once the test is completed and the results are documented, the septic tank pumping can begin. Pumping the septic tank during the inspection is crucial, allowing our inspector to examine the interior of the tank below the water line. This inspection helps identify potential issues and solutions associated with a tank in need of repair or replacement. After the septic tank inspection, we will re-evaluate the dispersal area to check for any changes in soil conditions after the hydraulic load test or pump test has been completed.

Either a failed hydraulic load test or changes in soil conditions may indicate improper septic system functionality, ranging from a simple clog or crushed pipe to a system reaching the end of its lifespan. If a change in soil conditions is observed, or there are poor results with the hydraulic load test, our office would recommend additional site work, likely performed by a local septic pumping company to waterjet the leach lines. This step can aid overall system performance and serves as an initial measure to determine what may be causing the poor test results or saturated conditions at the dispersal area. Although this may resolve some issues with the poor performance observed during the inspection, it is also possible that the dispersal area is nearing the end of its lifespan, and steps should be taken to begin the process of replacing the septic system serving the property.

Upon completing all essential on-site tasks for the inspection, we will consolidate the results and observations in a comprehensive Septic Inspection Report. This report is then provided to the client upon its completion, and plays an essential role in understanding the overall condition and functionality of the septic system serving the property.

BC Engineering Group: The Local Experts In Septic System Inspections

If you have any further questions or require assistance with your septic needs, our experienced staff at BC Engineering Group have successfully completed hundreds of septic system inspections in support of real estate transactions throughout Sonoma, Napa, and Marin Counties. Feel free to reach out to explore how we can support you in ensuring the optimal performance and reliability of your septic system.

California’s Construction General Permit (CGP) and Stormwater Pollution Prevention Plan (SWPPP) Requirements

Wed, 03 Jan 2024 19:30:01 GMT

California SWPPP & CGP: Avoid Penalties, Protect Waterways (Land Developers Guide)

Does your land development project require a Stormwater Pollution Prevention Plan (SWPPP)? If your land development project proposes construction activities that result in 1 acre or more of land disturbance, your project will likely require a SWPPP in order to comply with California’s Construction General Permit (GCP). The primary intent of the CGP is to set forth pollutant discharge requirements and regulations to help minimize construction related pollutants from entering local waterbodies and watersheds during rain events. By order of the CGP, land developers, commonly referred to as the Legally Responsible Party (LRP), are required to retain the services of a Qualified SWPPP Developer (QSD) to determine the project’s sediment risk level and to create a site specific SWPPP that will address sediment, erosion, and pollutant control measures that shall be implemented throughout the duration of the construction process.

In order to ensure that land developers implement and adhere to their project’s SWPPP, the CGP also requires land developers to retain the services of a Qualified SWPPP Practitioner (QSP). The project’s QSP is responsible for ensuring compliance with the site specific SWPPP that was developed by the project’s QSD by monitoring the site during all phases of construction and ensuring that the project remains compliant with the SWPPP and with the requirements set forth in the CGP. QSPs are also responsible for sampling stormwater runoff from the construction site during qualifying rain events, and reporting sampling results to the Regional Water Quality Control Board. Common duties performed by a project’s QSP are submitting the project’s Notice of Intent (NOI) which establishes coverage under the CGP, site inspections during construction, generating site inspection reports, pre- and post-rain event site inspections, stormwater sampling and testing during rain events, submitting stormwater sampling results to the Regional Water Quality Control Board, submitting Annual Reports, Changes of Information, and submitting the project’s Notice of Termination (NOT) to terminate permit coverage once construction is complete and the site has achieved final stabilization.

Failure to comply with the CGP and a project’s SWPPP can result in penalties issued to the developer (LRP) by local and/or State permitting authorities. Penalties may include construction delays due to permitting agencies requiring a stoppage of work, fines of up to $35,500 per day that a violation persists, and even jail time in extreme negligence cases. Navigating the requirements of California’s CGP and a project’s SWPPP can be a daunting process. At BC Engineering Group, our team of professional QSD’s and QSP’s assist our clients by coordinating all aspects of the project’s SWPPP and permit coverage under California’s CGP by keeping in close contact with the development team and providing recommendations for erosion, sediment, and pollutant control throughout the construction process. We encourage you to trust our team of professionals with your next SWPPP related project. Please give us a call if you have any questions or would like to learn more about SWPPP requirements.

Sonoma County Ordinance #6406 – Temporary Housing Opportunity?

Wed, 17 May 2023 17:59:30 GMT

Temporary Housing Opportunities

Recently the Sonoma County Planning Commission expanded the opportunities to provide temporary housing on most properties in the form of a RV, trailer, manufactured unit, or other movable housing. Previously, temporary housing was only allowed for care during illness/disability or to provide housing during major remodeling and rebuilding of housing. Now temporary housing is a possibility before even applying for a building permit for a potential housing unit.

An administrative permit will be required from the County with proof of access to utilities before temporary housing can be set up. Septic access can be in the form of a connection to an existing system with available capacity or a hold-and-haul contract with a licensed hauler. Septic capacity would have to be documented. The typical path is in the form of a bedroom swap or by documenting the condition and capacity of the existing septic system. The permits for temporary housing will have to be renewed on an annual basis.

Give BC Engineering Group a call at (707) 542-4321 or set up a meeting through our website www.bcengineeringgroup.com to discuss if you are interested in setting up temporary housing on your property or need help navigating the permitting process! We can help locate and research records on the existing septic system, perform septic inspections to determine the system condition and capacity, or help you through the permitting process.

General Waste Discharge Requirements for Winery Process Water (Winery Order)

Mon, 06 Mar 2023 21:54:01 GMT

Waste Discharge Requirements for Winery Process Water

The California State Water Resources Control Board adopted a general order for how wastewater is processed and discharged at winery locations in an ongoing effort to safeguard groundwater and surface water from wastewater discharges. The order is intended to protect groundwater and surface water quality, while giving wineries the flexibility to select compliance methods that best their site-specific situation(s), including tiering the compliance requirements to the winery size and associated threat to water quality.

The order also streamlines statewide permitting of currently unregulated winery process water discharges and establishes statewide consistency, while allowing regional Water Boards to focus their resources on compliance. The Wine Institute estimates that 2,036 of the 3,612 bonded wineries in California will be subject to the order.

Existing wineries not currently under coverage typically have or will receive a letter from the California State Water Resources Control Board indicating that they may be required to enroll under the Winery Order by January 20, 2024. These existing wineries are encouraged to complete an eligibility survey to determine if Winery Order enrollment is required. If enrollment is required, enrollment is highly encouraged by the California State Water Resources Control Board by January 20, 2024.

BC Engineering Group has the resources necessary to assist existing wineries in completing the eligibility survey, and if necessary, enrolling existing wineries in the Winery Order, as well as navigating the permitting process.

Hope you are enjoying the rain as the 2023 Wet Weather Groundwater Determination Tests Season Opens

Tue, 17 Jan 2023 18:39:43 GMT

County of Sonoma PRMD required testing for septic development for an onsite septic disposal system.

Wet-Weather Groundwater Determination Testing has opened for the majority of areas in Sonoma County as of January 2023. The testing season is currently open from January-March.

If you’re looking to upgrade an existing septic system or construct a new septic system, you may be required to have a Qualified Consultant perform a Wet-Weather Groundwater Determination Test in the area of the proposed septic improvements and required septic reserve area.

A Wet-Weather Groundwater Determination Test is used to observe the groundwater table level during the rainy season, through a series of test holes. A test hole will be dug to a minimum depth of 24” from grade and a perforated test pipe will be installed to monitor the groundwater depth.

This test is typically conducted between January 1st and March 1st, after having received 50% of the average seasonal rainfall for each defined geographic area, as listed in the County of Sonoma Onsite Wastewater Treatment System Regulations and Technical Standards .

Once an area has received the required 50% average seasonal rainfall and 0.8” or more or rainfall within a 48-hour period, a 10-day testing window is open to officially document the onsite groundwater table depth with the County of Sonoma.

Throughout the County leading up to a geographic area receiving the required rain amounts, Qualified Consultants will begin the work of installing groundwater test pipes in anticipation of the season opening. Testing hole depths change from site to site, but all pipes must be at least 24” in depth to prove the site has septic potential. If trying to upgrade an existing system, a much deeper depth may be required in order to meet the County requirements of 3’ separation from trench bottom to the groundwater table.

Addressing County Requirements for Groundwater Testing for Your Project

BC Engineering Group has performed this test on countless properties across Sonoma County and understand the process and specific timelines the work must be completed in. As a leading civil engineering design firm, feel free to reach out to us with any questions you may have regarding the process of documenting the groundwater table on your property.

Expert Witnesses in the Civil Engineering & Land Planning Professions

Tue, 06 Sep 2022 16:34:05 GMT

Expert Witness, Legal Services for civil engineering and land planning

In litigation cases, attorneys occasionally need to seek the support of non-law professionals to aide with interpreting conditions, codes, and other matters associated with their cases. These individuals are referred to as expert witnesses. An expert witness will review documentation related to the subject litigation case and form opinions that they share with the attorneys. For land use disputes, the areas that civil engineers and land planners can provide expert review and form opinions is vast.

A civil engineering expert witness can bring extensive knowledge to many types of cases that relate to land disputes, construction practices, and clarification on permitting regulations. A civil engineer is commonly retained as an expert witness for cases that involve soil erosion, grading, septic systems, encroachment, roadway construction, easements, and more.

BC Engineering Group is a professional, highly accredited firm that has served on several litigation cases involving roadway construction, improvements within easements, septic systems, real estate transactions, and disputes between neighbors.

With BC Engineering Group as an expert on your case we bring over 35 years of civil engineering experience, high levels of preparation, attention to detail, and technical understanding to all circumstances.

Need an expert witness in the civil engineering or land planning arenas? We have the professionals, let us help.

Hydraulic Calculations for Water Meter and Lateral Sizing

Fri, 04 Mar 2022 14:30:03 GMT

Calculations for Lateral Sizing in City of Santa Rosa

The City of Santa Rosa has recently been requesting hydraulic calculations to be performed by a licensed civil engineer to confirm that the velocity in service laterals and water meters will not exceed 15 feet per second. This will cause less wear and tear on the service lateral and meter, and limit the water loss due to small breaks and leaks. These calculations conform with American Water Works Association (AWWA) M22 Manual standards, which are the national standards for water systems. These standards combine best practices within the industry and the standards of other professional societies such as the Uniform Plumbing code.

To conform with the AWWA M22 Manual standards BC Engineering Group uses an iterative approach. The initial assumed water meter size is based on the AWWA meter requirements. Next, the velocity is calculated, and the water meter may be resized from the initial assumed value. Once the selected water meter yields a velocity that is within the appropriate operating range, comparison with other design deliverables is required. BC Engineering Group then compares the calculated lateral and water meter sizes to the recommendations from the fire suppression consultant to ensure that it will not conflict with what is necessary for the fire suppression system.

In certain cases, the calculated velocity can exceed the mandated velocity while conforming with the AWWA meter sizing recommendations when the project is located within a high-pressure area of the municipal water system.

AWWA recommends that water meter sizes match the service lateral diameter to limit head loss (pressure loss). AWWA publishes a set of recommendations for meters based on maximum and minimum flowrates. Water meters are less effective at velocities outside these recommendations. This can cause increased maintenance demands and incorrect billing to customers.

Senate Bill 9-The California Housing Opportunity and More Efficiency (HOME) Act

Tue, 11 Jan 2022 16:19:21 GMT

Streamlining The Creation Of Rental Units On Existing Lots.

Senate Bill 9 allows a streamlined process for homeowners to create a duplex or subdivide an existing lot. This bill builds on other successful legislation around ADUs and JADUs, to help address the challenges of affordable housing.

By subdividing or creating duplex’s families can provide affordable rental opportunities for others in their community. This is a bill that will benefit homeowners not investors as owner occupancy is a requirement and prohibits the lot splits on adjacent parcels by the same owner.

As part of the process the property must meet specific qualifications, these qualifications protect historical neighborhoods, environmental quality, and the overall look of neighborhoods. SB9 does not allow more than four units on a single-family parcel and encourages all building of units to follow neighborhood appearance.

This legislation provides new and exciting opportunities for homeowners to build intergenerational wealth within their own families, while providing rental opportunities that will help others that may be priced out of the rental market.

Under Construction! New VA Outpatient Clinic in Santa Rosa

Fri, 17 Dec 2021 16:59:26 GMT

BC Engineering Group is honored to be the project civil engineer and landscape architect

A new Department of Veterans Affairs Community Based Outpatient Clinic (CBOC) is currently under construction in southwest Santa Rosa. BC Engineering Group is proud to have partnered with the developer Santa Rosa VA LLC on this significant project for our community. We are also honored to have been selected as the project civil engineer and landscape architect through a competitive Request for Proposals process with Ryan Companies, the General Contractor.

The VA applies specific and unique criteria to the selection of new project sites to ensure that all new facilities offer the greatest benefit and ease of access for local veterans. The potential area for the new facility, as identified in the original RFP, ranged from Rohnert Park in the south to Healdsburg in the north. Fortunately, two available parcels comprising 8 total acres in Santa Rosa’s Corporate Center business park met the VA’s criteria. Upon notification of consultant team selection and contract award, rigorous planning and collaboration began for the new 58,000+ square foot medical facility in early 2019.

Our scope of consulting services included preparation of preliminary plans for planning approval, and preparation of improvement plans (construction documents) for construction permitting. Our improvement plans included a demolition plan, site and amenities layout, grading, stormwater control , utilities design, construction detailing, planting plan, and irrigation plan.

The City of Santa Rosa recognized the importance and value of the project to the community and, in support, allowed the developer to submit for Design Review and Improvement Plan review concurrently. This good will allowed for an expedited entitlement and permitting process, saving months of time compared to a typical development application process. Our staff worked closely with City staff, the developer, and the consultant team to maintain a clear direction and ensure all project milestones were met on a very aggressive schedule.

BC Engineering Group staff has been deeply involved at each step of the way and continues to be an important resource for consultant team members which are headquartered outside of California. Our firm is currently providing civil engineering and landscape architecture construction support services to the Ryan Companies, and Qualified SWPPP Practitioner (QSP) services as well. The QSP services are a requirement of the City of Santa Rosa, as well as the State’s Water Resources Control Board. This project complies with the state’s Construction General Permit which requires best management practices (BMPs) for reducing storm water pollution in projects that disturb more than one acre for development. BC Engineering Group is currently providing site monitoring and observations of the erosion and sediment control BMPs, and storm water testing during storm events in accordance with the requirements of the General Permit.

Our team is proud of the work we’ve contributed to this noteworthy project, and the transformation of the site has been remarkable. Once sitting idle for decades as an open field, the project site will soon be complete with a state-of-the-art medical clinic, meandering perimeter and internal pathways, a healing garden, onsite storm water management, and extensive landscaping featuring low water-use native plants. We are excited about opening day on the near horizon, and most importantly the impact this facility will have on our veteran family members and neighbors.

BC Engineering Group is available to assist with your project, regardless of size. As a leading civil engineering, wastewater, and landscape architecture firm, BC Engineering Group is here to answer any questions you may have. Our wide range of services includes planning support, project programming, schematic design, preparation of improvement plans, and construction services. Our staff of talented engineers, technical support staff, and landscape professionals are eager to talk with you about your project goals and how to make them happen. We cater our services directly to your project needs.

How Senate Bills SB35 and SB330 Help with Development for Affordable Housing

Wed, 08 Dec 2021 22:04:51 GMT

What To Know About Senate Bills SB35 and SB330

With California having some of the highest housing and rent prices in the country, affordable housing is a top priority in the state. As recently as 2019 two State bills, SB35 and SB330 have created requirements and eased timeframes to help relieve the current housing situation.

Senate Bill 330 “The Housing Crises Act of 2019”

The purpose of SB330 is to streamline and reduce the time it takes to approve housing developments. The bill also redefined “Housing Developments” to include residential housing and mixed-use projects, with 2/3 of the square footage dedicated to residential units and transitional or supportive housing. The bill also allows housing development projects to receive certain vesting rights through a preliminary application process. By reducing the processing time, the goal is to create certainty within the building process.

Senate Bill 35 2017-Helping the Rental Market

The goal of SB35 is to increase the housing supply within cities and counties that have not made progress toward meeting affordable housing goals, that are mandated by the state. For these cities and counties, multi-unit housing developments will have a more streamlined and expedited process, making it easier to get to construction. The bill also requires that these developments designate a percentage of units that meet a percentage of below market housing to help the cities/county meet their affordable housing goals.

BC Engineering Group has extensive experience with planning, civil design, and landscape architecture for all types of residential subdivisions and developments, including multi-unit and affordable housing projects.

Septic Perc - A Real Estate Industry Misconception

Tue, 03 Aug 2021 16:30:02 GMT

Septic “Perc”- aka Percolation Test, for septic development in Sonoma County

Whether a lender, real estate agent, buyer, underwriter, or seller, the statement that a property has an existing “perc” is tossed around everywhere in Sonoma County’s real estate industry. This is a big misconception, and an alarming one.

The word “perc” is slang for a septic system development related Percolation Test. A percolation test does not guarantee septic development potential for a property. Rather, it indicates the permeability (ability for water to pass through) of the soil in the tested area. The results of a percolation test in Sonoma County provide one critical design parameter for septic system design calculations and plans and in no way does it illustrate a number of bedroom potential. Again, it only indicates if the soil tested will pass water (and ultimately sewage) quickly or slowly and gives a Soil Application Rate to the person designing the septic system. A good rule of thumb: If the percolation test rates are fast, the septic system will be smaller in size than if the rates were slow.

So, if a “perc” does not guarantee if a property can have a septic system, then how can an interested party get a guarantee? The answer is simple, a guarantee can be provided by obtaining a septic system construction permit or a vesting certificate from the County of Sonoma. Septic permits and vesting certificates are valid for three years after issuance, and if not renewed will expire.

To reach a guarantee, by obtaining a permit or vesting certificate, takes several steps, one of which is a “perc”. A soil investigation with a County representative is the first step, followed conventionally by a percolation test, and a septic system design is the final step necessary to submit for a guaranteeing County entitlement. In some cases where the property is flat (less than 5% ground slope in the tested area) or in other rare conditions, there is a wet weather groundwater test that is also required to submit for a County septic permit or vesting certificate.

Unfortunately, going through the steps to obtain a guarantee will take anywhere from 4 months to over a year! This is way too long of a wait period to endure during a typical escrow. But there’s a hybrid approach to serving buyers and sellers that can be done in a number of days and still provide high levels of confidence and septic development insight.

Now, the good news is that not all real estate transactions need a guarantee, but rather a strong indication that septic suitable conditions and area exist at the subject property. This can typically be achieved by exploring the site’s soils with an excavator. This step is referred to as a soil investigation, or if performed with the County present, is called a Pre-Perc Site Evaluation. Preliminary sizing of a septic system can also be performed by a consultant such as BC Engineering Group to help in determining if the site’s septic area will be big enough to support the ultimate residential uses, for example number of bedrooms or homes desired on the site.

BC Engineering Group strongly encourages our clients to have a soil investigation done with our staff and an excavator before taking ownership of any property that will need septic system work to meet the client’s goals. Just by looking at the property and the sub-surface soils, we can confidently forecast whether the septic potential for the property is strong, marginal, or weak. If the confidence level for septic conditions is strong, clients can move forward with their transactions self-assured. If marginal or weak, we typically recommend that our clients perform additional steps in determining the septic development potential, such as taking the other steps as referenced in the fourth paragraph.

So, next time you hear that a property has an existing “perc” or you think about making such a statement yourself, remember that it only means that soil testing was done at the subject property to determine how fast water/sewage will move in the soil, not how big the septic system will be or how many bedrooms it will support.

Water-Wise Landscapes for Your Residential Property

Mon, 26 Apr 2021 18:00:03 GMT

Northern California Water-Wise Landscapes

Did you know that half of our drinking water is utilized for landscape irrigation? Many people would be shocked at this revelation, and perhaps even motivated to reconsider their residential landscaping and irrigation needs. Residential landscapes are most often a personal choice related to function, aesthetics, and preferred level of maintenance. For instance, homeowners often desire lawns for their children to play on, for their pets, or simply for their green color. However, there are other landscape possibilities to consider with significant benefits such as food production, habitat creation, and even water conservation. Low water-use landscapes are often more economical to maintain and irrigate, and can provide many additional benefits including habitat value, species diversity, energy conservation, aesthetic beauty, and reduction of waste transportation.

If you are one of the many in our community who have been working from home for the past year, you have spent much time looking at your landscape and perhaps even considering an upgrade. If you have a thirsty lawn that you no longer wish to irrigate or maintain, there is no better time to convert it to a low water-use native garden given our extended period of drought conditions. Some additional food for thought: one square foot of lawn requires about 25 gallons of water per year. For a typical residential lawn of 600 square feet, that equates to 15,000 gallons of water, or more than enough to fill a 12’x24’ pool every year.

Whether you are looking for assistance with a yard freshening up, turf conversion, phased projects, or complete landscape renovation, BC Engineering Group is here to assist. Our staff includes talented landscape professionals who are eager to talk with you about your project goals and how to make them happen. We provide landscape evaluations of your planting and irrigation, recommendations and design of new amenities, and preparation of conceptual landscape plans through construction documents for projects of all types and sizes. In addition to planting and irrigation expertise, we can provide a full range of landscape architecture consulting services including design of patios and hardscapes, pergolas, outdoor kitchens, walls, and site grading. We cater our services directly to your needs.

BC Engineering Group is available to assist with your landscape project, regardless of size, and can walk you through the process of design development and permitting, if needed. As a leading civil engineering and landscape architecture firm, BC Engineering Group is here to answer any questions you may have. Please don’t hesitate to call and talk to us about your project, our process, and how we can be of assistance. To learn more about our services, please reach out to us at (707) 542-4321.

Fire Rebuild Process, Services, and Assistance in Northern California

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 15 Sep 2020 17:15:11 GMT

Civil Engineering Design Services for Fire Rebuild Projects in Northern California

As recovery efforts begin, it is important to know what steps should be taken to rebuild as effectively and efficiently as possible. We are here to help you navigate through this strenuous process.

Step 1: The first step to take is for the property owner to file an Insurance Claim. This will ensure a timely response for the rebuild process.

Step 2: Once a claim has been filed the second step is Debris Removal. This is a required two-phase process; removal of household hazardous waste and removal of other fire-related debris. It is important to note that a grading permit is not required for debris removal. See link below for further debris removal information.

http://www.sonomacountyrecovers.org/debris-removal

Step 3: Once debris removal has been completed; it is time to begin the Rebuilding Design and Permitting Process. The property owner will need to obtain a design professional, typically a civil engineer, drafter/designer, or architect, to prepare construction plans for the new building(s). Property owners should work with design professionals to incorporate all their desires within the new building site. BC Engineering Group is happy to answer your questions and fill the design professional role for your project.

Once construction plans have been prepared, it is time to apply for the corresponding permits. Both City of Santa Rosa and Sonoma County have dedicated Resilient Permit Centers exclusively for property owners affected by the fires. Design professionals will work directly with the Resilient Permit Centers to guide property owners through the permit and review process.

Step 4: Once construction plans have been approved and permits have been obtained Construction and Inspections can begin. The building process will include grading and groundwork, foundation, framing and walls, landscaping, etc. Inspections will be required throughout the building process along with a final inspection and activation of site utilities.

Step 5: Move In! Once the final inspection is completed the property owner will be granted an occupancy permit. Once a Certificate of Occupancy is received, it is time to move in!

What is a Pre-Perc Site Evaluation?

Wed, 04 Dec 2019 05:56:29 GMT

County of Sonoma PRMD required soil testing for septic development for an onsite septic disposal system.

A Pre-Perc Site Evaluation is the formal documentation of the onsite soil conditions located on a subject parcel. This is commonly mistaken for a percolation test, or perc test. Although both are testing procedures for gathering data related to soil for use in a septic design, one is used to determine septic system type, while the other is used to determine the overall size of the proposed septic system.

Well, which one is which?

A Percolation Test is performed by digging many test holes across a subject parcel and over the course of two days adding water and monitoring the drop or percolation rate of the soil. Typically, these tests are only required by the County of Sonoma on undeveloped properties or during the process of sub-dividing a parcel. The average percolation rate that is calculated after the test has been performed will be the major factor in the overall size of the proposed septic system.

A Pre-Perc Site Evaluation is the process of documenting the soil depth and composition for use in a onsite sewage disposal system. This process must be performed by a Qualified Consultant and a member of County of Sonoma Well and Septic Department. During the site evaluation, a backhoe or mini excavator will also be required to be onsite to dig profile holes in the area of the proposed septic system location and required reserve area.

After each profile hole is dug, the soil depths and compositions are logged throughout the total depth of the hole. The Qualified Consultant will be looking for any changes in the soil throughout the depth of the hole, these changes are called “horizons”. Each soil horizon will be measured in depth and documented with the specific characteristics of the soil observed within the horizon. These characteristics and depths associated with them determine whether a site has septic potential, and if so, what type of system the soil can support.

The subject parcel must have at least 24” of septic suitable soil located from grade to have septic potential. If we only find the minimum soil depth required, the property would only have the potential for an above ground septic system like a mound, or an at-grade mound with pre-treatment. The deeper we can find septic suitable soils the better, as it will allow for other septic system types to be designed.

If you’re looking to expand an existing septic system to allow for additional bedrooms or an accessory dwelling unit, you will have to perform a Pre-Perc Site Evaluation if one hasn’t been performed on the property previously. The process of expanding an older existing gravity trench based septic system can be more challenging then designing a new system, as the soils present in the location of the existing system will need to meet the County’s requirements for depth below trench bottom. Gravity septic systems typically requires 66” – 72” of acceptable soil type to meet the County requirements to allow for the septic system to be expanded.

A large portion of properties across Sonoma County located in basin areas will also require a Wet-Weather Groundwater Determination Test be performed if looking to expand or develop a septic system on a subject parcel; please see our blog Groundwater Testing for Septic Development in Sonoma County for additional information.

Addressing County Requirements for performing a Pre-Perc Site Evaluation for Your Project

BC Engineering Group has performed Pre-Perc Site Evaluations on hundreds of properties across Sonoma County, we’re able to handle all aspects of the project from developing site exhibits, submittal to the County, scheduling of the backhoe and performing the onsite soil work.

Santa Rosa LID Requirements Impacting Development Projects

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Thu, 12 Sep 2019 04:41:20 GMT

Stormwater treatment and retention requirements causing re-design.

When creating over 10,000 square feet of impervious surface, your project will need to follow the low impact development guidelines for stormwater treatment and capture. The Guidelines for stormwater treatment and capture is outlined in the “Storm Water Low Impact Development Technical Design Manual.” The technical manual was implemented in 2017 and has revisions that can drastically change stormwater management designs.

The main change in the technical manual is the parameter for the water quality design storm used for all SUSMP calculations. The old manual uses the 85th percentile 24‐hour storm event, while the new design manual uses capture and retention of 100% of the volume of runoff generated by 1.0” of rain over a 24-hour period. This can cause unwanted designs to your project.

The team here at BC Engineering Group has already supported multiple projects in designing new methods to handle the new requirement. Another requirement outlined in the new technical design manual is the need to perform field tests and calculations to ensure that all ponded water will drain within 72 hours to eliminate the concern of attracting vectors such as mosquitos. This creates another constraint for projects which our team is well versed in addressing.

If you want help figuring out if your project will be impacted or if you need a new consultation regarding stormwater management design, please call us. We are here to help!

Addressing Stormwater Management For Your Project

The BC Engineering Group staff has submitted numerous Low Impact Development Designs and can walk you through every step of the process.

Healing Landscapes

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Fri, 21 Jun 2019 04:26:45 GMT

Healing Gardens Are on the Rise

You may have noticed a sense of calmness or ease when spending time in a space surrounded by nature, it’s not just your imagination. Studies have found landscapes and gardens to have a healing impact emotionally, psychologically, and physiologically so it’s no surprise that they’ve implemented gardens in some hospitals and various other healthcare facilities around the globe.

In 2018 the American Society of Landscape Architects held a meeting that addressed Garden Design in Healthcare Facilities. Creative minds came together to discuss healing garden projects, success stories, and effects of landscape design on people. Healthcare facility gardens are a rerising trend in the West, though their effects are widely used and adopted in the East, specifically China. Western medicine saw a significant drop in the integration of gardens in hospitals in the mid 20th century due to international contentions, and the West’s desire to keep international elements and influences away (Jiang).

Years later, we are seeing a rise in the implementation of the healing gardens into different health facilities all over. In the ASLA meeting, a Delaware based healing garden project was discussed, Jiang addresses a Bay Area healing garden in his research, and Therapeutic Landscape Network provides an extensive list of existing gardens in health care facilities throughout the United States. After years of decline in the instances of gardens in health care, the benefit of the natural setting is once again being recognized and implemented.

Extensive research has shown a wide variety of benefits in the integration of nature and gardens in health care facilities. Natural landscape as been shown to help with stress, improve healing time, increase comfortability and calmness, and with the right design promote movement (Jiang, 2014). With all the clear benefits of incorporating nature into the hospitals and health care facilities, it may be time to consider how to put together your own zen garden.

The BC Engineering Group is available to assist in the custom design of healing gardens and can walk you through the process of design development.

Sustainability in Residential Landscape Design

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Wed, 12 Jun 2019 04:24:13 GMT

Contributing to sustainability efforts in the Sonoma County area

With a population of over 500,000, and a housing vacancy rate that is less than that of the state’s and the nation’s average, Sonoma County clearly continues to be a high demand County for renters and homeowners (Sonoma County Economic Development Board, 2018). With a large number of residences comes responsibility in maintaining a sustainable space to help keep the County green.

Though sustainability has been used as a pretty loose term, the American Society of Landscape Architects defines a sustainable landscape as “responsive to the environment, re-generative, and can actively contribute to the development of healthy communities” (The American Society of Landscape Architecture, 2017). All landscape designs are unique to the individuals contributing to the development and creation of the space so it’s important to consider how to implement a landscape layout that will fit your needs while also benefiting the health of the home, community, and local ecosystem. A few things to consider when working with landscape design are plants, pollution, and water (Bean & Yang).

What kind of plants are being implemented into the landscape design? Are they native, and if not, what are the native options that can be taken into consideration? The California Native Plant Society (CNPS) encourages the use of native plants in landscapes of all varieties in order to promote a better working local ecosystem. The CNPS provides information to see which plants are native, and to where. To learn more about CNPS and choosing local plants contact us at BC Engineering Group .

When considering the effects of pollution, a question to be addressed is if the landscape is helping to reduce the pollutants in the air or water? Something as simple as the grading of the landscape has an effect on the pollution. Without going through proper design channels, there’s a possibility for a residence to create water run off which can carry chemicals, such as those used in pesticides, to a neighbor’s property, or even further to the natural bodies of water (Bean & Yang). Layout of the plants is important, as implementing trees and other vegetation has the capacity to act as a barrier for air pollutants (USDA National Agroforestry Center, n.d.).

The landscaping of a single residence may not seem like a significant contribution to the ecosystem that exists in our county. This is why it’s important to consider all of the homes that are in our area, with so many residences in Sonoma County and with a continual demand, each sustainable landscape makes an impact in maintaining a mutually beneficial ecosystem.

The BC Engineering Group staff has worked with many clients to develop custom sustainable landscapes and can walk you through the process of design development. As a leading civil engineering and landscape architecture firm, feel free to reach out to us with any questions you may have regarding landscape design. Take advantage of our experience and contact us today with any landscape design questions or needs you may have; we are here to help.

BC Engineering Group Acquires Firma Design Group; Strengthening Its Position in the Civil Engineering Industry

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Fri, 31 May 2019 04:21:41 GMT

BC Engineering Group Acquires Firma Design Group

BC Engineering Group , a 19-person Santa Rosa based civil engineering and land planning company, has purchased Firma Design Group, a 10-person Santa Rosa based civil engineering and landscape architecture firm.

The purchase, which occurred in late April 2019, is on the heels of a blossoming business relationship between the principal of each firm. Thomas Billeter , principal engineer and founder of BC Engineering Group, and Martin Goldsbrough, principal and a founding member of Firma Design Group, have been supporting each other on projects for several months leading up to the business transaction. Mr. Goldsbrough brought up the idea of a sale to Mr. Billeter in 2018. “The idea of making a formal tie between the two companies was exciting and appealing, the discussions and negotiations progressed quickly from there” said Mr. Billeter.

Both firms, although competing with one another in certain areas of service, differed substantially in clientele being served. According to Mr. Billeter, “Firma Design Group’s clientele and areas of service were seen as very valuable, and if purchased would provide us with a lot of diversification, specifically geographically and in the types of clientele served.” Firma Design Group serves many public clients throughout the bay area, while BC Engineering Group primarily serves private clientele throughout California. “The addition of Firma Design Group has made BC Engineering Group substantially more recession proof overnight” said Mr. Billeter.

Both companies have offices in Santa Rosa. BC Engineering Group has no immediate plans to close either location, one north of Coddingtown and one in downtown Santa Rosa. With the bolstered staff, the owners of BC Engineering Group intend to expand geographically in the next 24 months to neighboring Counties.

Commercial Cannabis Water Source. What You Need to Know!

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Thu, 07 Mar 2019 05:07:46 GMT

Water Source Considerations For Commercial Cannabis Cultivation

When you think of commercial cannabis one of the first important things to consider, is how the cannabis plants will be watered. This can be one of the most important factors to consider when beginning your commercial cannabis operation. Most cultivators may believe that they have water rights to a waterway on their property or they plan on using a natural spring that they have always used, however, this may no longer be the case. There are four types of water sources that you may consider for your cannabis cultivation project. Those four sources are municipal water, recycled water, surface water, and groundwater. Read on for details of these sources.

Municipal Water:

This water source is typically referred to as “Tap Water.” This is treated water that is supplied to households and businesses using underground pipes. This water typically comes from large wells, lakes, rivers, or reservoirs and is then processed at treatment plants to meet EPA standards prior to being delivered to the customer. A municipal water supplier is defined in the California Water Code Section 13575 . If this type of water is intended to be used for commercial cannabis cultivation, the applicant shall provide documentation from the municipal water source stating that adequate supplies are available to serve the proposed use and will be provided by the municipality.

Recycled Water:

A common source for recycled wastewater is typically from a municipal recycled water supply and is usually for non-potable uses only. Other forms of recycled water are captured rainwater from buildings or other impervious surfaces for irrigation, and gray water recycling typically used for landscape irrigation. If municipal recycled water is an option in your area, call your local municipal water supply company to find out more information regarding cost and possible supply. Rain water capture is a good way to augment your water supply or can be used to recharge onsite ponds or reservoirs. If your project is located in an area of limited water sources, constructing an onsite pond or reservoir is an option to store storm water to be used during the summer months. If you have any questions regarding stormwater storage contact us here at BC Engineering Group and we can help you figure out the best reservoir location and other potential water storage options to keep your cannabis cultivation dream alive. Remember that when choosing to use a recycled water source you must also provide an adequate on-site potable water supply for employees and other uses.

Surface Water:

The water that flows in rivers, lakes, and reservoirs is called “surface water.” This water source can be a natural spring or any type of surface water flow. One common practice in cannabis cultivation is diverting surface water to an artificial pond for storage, and proper permits are required for this type of diversion. In order to use surface water, you will need an existing legal water right and, if applicable, a Streambed Alteration Agreement issued by the California Department of Fish and Wildlife among other entitlements. Be aware there is a forbearance period on surface water diversion. This means you may only be permitted to divert water during the wet season. In order for this water source to supply enough water during the cultivation season, projects typically need to design an onsite reservoir to store sufficient water for growing months. This process will likely entail having a grading permit for the earth movement and having the reservoir designed by a licensed professional, such as BC Engineering Group.

Groundwater Well:

In the rural parts of California, groundwater can be the most common type of water source. This is a great source of water for cultivation as well as an on-site water supply for employees and other uses. If you find yourself in need of a new water source, drilling a groundwater well can be a very cost-effective option as long as there is groundwater available at your site. Make sure to check with your governing agencies to ensure there are no restrictions on groundwater. Some local agencies will have regulations governing groundwater within specific availability zones and high or medium priority basins. If this is the case, there can be such regulations as no net increase in water use or a hydro-geologic report showing adequate water supply from a well. These types of regulations can remove groundwater as a possible water source for cultivation. There are other options such as trucking in recycled water or building a reservoir if your site permits.

Planning and Permitting for Modular Homes in Sonoma County

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Sat, 02 Feb 2019 05:05:18 GMT

Building Permits for Manufactured Homes

Since the wild fires destroyed homes all over California over the past few years, there has been an increase in demand for manufactured and modular homes. These homes are occasionally a great fit for fire victims and they are affordable. Modular homes come in many shapes and sizes providing a wide range of options in both price and style for clients. Some of the other benefits include shorter build time, quality of materials and construction, and energy savings on production. Since the homes are built in a facility, the process goes much faster and there is substantially less waste associated.

These homes sit on a permanent foundation that make the homes resemble a traditionally built home. The difference between manufactured and modular homes are the governing building codes. Manufactured homes are built in a factory and governed by a federal building code. Modular homes on the other hand, are built in a factory but are governed by local or state building codes. Since modular homes are already built to state building codes, the permitting process is more streamlined than that of a typical stick built home.

Obtaining a Building Permit for Modular Homes:

There are different requirements and procedures to apply for a building permit for a modular home. This is due to the plans meeting state and local building codes. This process is also different if your property was damaged during the wild fires.

Fire Damaged Property Here in Sonoma County:

If the home was lost in the October 2017 wild fires, you will need to submit your building permit application to the Sonoma County Resiliency Permit Center. Most of the required documents are provided through the modular home company. There are however, 5 additional documents that will need to be submitted along with the modular home manuals and plans;

A site plan prepared by a license professional
A geotechnical report
Geotechnical plan review letter
A special inspection form
A grading permit questionnaire

Once all the required documentation is provided you can submit the building permit application and due to the expedited permitting process at the Resiliency Permit Center, you can expect plan review to be completed within 10 business days.

Fire Damaged Home Outside Sonoma County

There has been over 20 wildfires that have caused damage to structures all over California since 2018. If you are looking to rebuild using a manufactured home it is best to reach out to us here at BC Engineering Group to see what services, if any, are provided for fire victims in your specific County. The modular home building permit process can change slightly depending on the County specific requirements. If you or someone you know has been affected by these wildfires and want to know more about a specific County’s process, contact the BC Engineering Group team on line via our contact page or by phone at 707-5424321

New Modular Home Project (non-fire damage related) in Sonoma County:

If you are developing a property and choose to purchase a modular home, you will need to submit your building permit application to the Sonoma County Permit and Resource Management Department. The required documentation does not differ from a fire damaged property. However, there is a possibility to avoid the requirement of the geotechnical report and review letter. Permit Sonoma conducts Site Evaluations, which is a way for the County to determine the existing site conditions and whether or not a geotechnical investigation will be needed. In order to schedule a site evaluation, submit two site plans, pay fees, and provide an application to the governing jurisdiction. Depending on the County staff’s availability, the site evaluation is typically scheduled within 2 to 4 weeks. BC Engineering Group can coordinate the County Site Evaluation work for you, simply reach out to us for help.

BC Engineering Group’s Wastewater Division Has Expanded!

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 15 Jan 2019 04:56:39 GMT

BC Engineering Group Expands Wastewater Services

We are pleased to announce that BC Engineering Group has increased its team by forty percent in the last four months. Due to the fires that took place October 2017, BC Engineering Group has become consumed with helping to rebuild the community. Our Wastewater Department had been overwhelmed and overworked helping fire properties to begin rebuilding. The addition of our new staff is to further support our projects as well as our community that we serve.

We are excited to announce the promotion of Jonathan Erker, who has been with BC Engineering Group since the first quarter of BC Engineering Group’s inception. Jonathan attended Santa Rosa Junior College for civil engineering and surveying technology and has become a vast source of knowledge for septic design, regulations, and construction practices in northern California jurisdictions. Jonathan is now our Wastewater Department Head who coordinates, manages, and oversees all wastewater projects with the firms Principal Engineer, Thomas Billeter , and Senior Wastewater Project Manager, Jessica Chavez, E.I.T. His adaptability, quick learning style, along with his high attention to detail and organizational skills has made him a true asset to the Wastewater team

Laura Irwin, now our Wastewater Department administrator, joined BC Engineering group over a year ago. Laura oversaw the administrative duties, both Wastewater Department and the Civil Department. This became an overwhelming task, so the hiring of Sarah Maudlin was to oversee the Civil Department tasks, and now Laura can focus her organizational skills to assisting our Wastewater Department with anything they need. Morgan Peterson , another new addition is the new Administrative Assistant for the Wastewater division, providing further support to the team. Morgan graduated Spring of 2018, from Sonoma State, with a bachelor’s degree. She oversees all administrative areas of BC Engineering Group and works side-by-side with many of the Senior Project Managers to help guide projects smoothly as well as working alongside our engineers out in the field.

Another addition, Matthew Sullivan , who just recently graduated from Santa Rosa Junior College with a natural science degree has joined our office as an engineering technician. Matthew has been working closely with our engineers out in the field as well as assisting in the office helping draft plans for septic systems.

With the expansion of our Wastewater team we are more efficient and productive, and able to serve a larger bandwidth of wastewater projects. We are excited and looking forward to serving our community in a larger role and continuing our growth trend.

Rebuilding After The 2017 Napa Fire Complex

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Thu, 06 Dec 2018 04:53:52 GMT

Rebuilding after the 2017 Napa Fire Complex

The 2017 Napa Complex Fire also known as a the “Atlas Fire” burned about 51,000 acres. Many people lost their homes and/or businesses due to the fire. The County has taken measures to expedite processing of permits for fire victims. Fire victims are also able to apply for a fee reduction for their required permits. The County has created three review categories that range from 7 to 28 days for review time. The three categories are 7 business day/expedited, quick permit-priority processing over non-fire related permits, and standard permit-priority processing over non-fire related permits. The fee reduction is available for all fire rebuild projects including commercial and residential accessory structures.

Types of projects that qualify per category:

7 business day / expedited: Similar building footprint replacement of legally existing residences, guest houses, and second dwelling units up to 125% size of burned residence in same general location with no increase in bedrooms.

Quick Permit-priority processing over non-fire related permits: Fire Rebuild accessory structures that meet the Quick Permit criteria. Some examples are single story Ag buildings, carports, gazebos, pump house, storage buildings, and all demolition permits.

Standard Permit-priority processing over non-fire related permits: All other permit applications that are not covered under the first two categories.

Things to consider:

Your property must be cleared for rebuild. This means all debris and ash must be removed and soil testing completed. A letter from the County Environmental Health Division certifying completion must be on record before a building permit will be issued.

If the fire damaged property previously had a septic system that you plan on utilizing for your new home. You will need to complete an evaluation of your system. If you plan on rebuilding with a similar foot print that does not exceed 125% of the previous structure, you may utilize the existing septic system as long as the inspection reveals that it is in good working condition and not considered a cesspool. If you plan to rebuild with a footprint exceeding 125% of the original structure, the system will need to meet current Napa County Code requirements.

Napa County has also developed a Fire Rebuilds dashboard. This is a near-live view of issued and pending permits in Napa County. You can access the dashboard by clicking on this link: http://bit.ly/firerebuilds

Rebuilding After the Redwood Complex Fire

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 27 Nov 2018 04:51:00 GMT

Fire Damaged Rebuild and Permitting in the Redwood Valley County Water District

County of Mendocino hosted a Town Hall meeting on Thursday October 11th, in Redwood Valley, with the key topics of water system improvements and a planned water system replacement project. This meeting was to inform and address any questions from residents about the Redwood Valley County Water District infrastructure project specifically residents served by Redwood Valley County Water District. The project has been completely funded by state and federal disaster relief funds. The allotted funds will be used to upsize existing water lines and create loops where dead ends exist. The improvements will cover about 4-miles; with 3-miles being replacement and 1-mile of new installation. This will update current water lines by creating enough pressure and flow to support fire sprinklers which are required under the building code, Title 24. The current water infrastructure was developed prior to some of the safety requirements required under California’s new building code. The funding will cover all costs of the public right of way improvements.

What does this mean for property owners?

The project is still in the preliminary phase and is expected to break ground in 2020. The Project and this blog only pertain to property owners that are within the service area of the Redwood Valley County Water District. The project will replace the water main in the street and upsize laterals to 1” if needed. One of the most common questions from community members and victims of the fire was, “what am I going to be expected to do?” There are two easily obtainable options to rebuilding.

Option A: The property owner can choose to upgrade the lateral to 1”, if it is not already, from the property line to the building connection. If choosing this option, the home owner will not receive a certificate of occupancy if the public improvements have not been completed. The reason for this is the required fire sprinkler system is anticipated to be non-operational or have unsupported flows until the public improvements are constructed.

Option B: The property owner can purchase a water tank and booster pump to supply the fire sprinkler system. If a home owner chooses option B, they will not be required to upgrade the water lateral as long as they have an adequate tank and booster pump supplying the sprinkler system. Option B is an alternative which will allow home owners to gain occupancy of their homes prior to improvements being installed in their area. After installation of water system improvements are completed, the home owner will have the option of staying with the tank and pump or connecting to the new 1” water lateral.

The goal of this project is to ensure all new fire rebuilds will have adequate flow and pressure to support the required fire sprinkler system. The County will support this goal by expediting permitting for fire rebuilds. The County’s staff is aiming to be able to approve permits within 1 to 2 weeks.

Final inspection

While there are some exemptions covered in Title 25 that cover manufactured homes or class K housing, a final inspection will not be performed until the water system is updated. This means you will have a system in place that will be adequate enough to support your design fire sprinkler system. Again, this is done by either upsizing the connection or having a supplemental tank and pump feeding the sprinkler system only.

Cannabis Stormwater Runoff Monitoring

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Sat, 17 Nov 2018 04:46:47 GMT

Commercial Cannabis Monitoring and Reporting Program

The rain is on its way.

With rain comes stormwater runoff. The State Water Resource Control Board requires monitoring and reporting of cannabis cultivation sites during months of rain events. The tests for stormwater runoff include a turbidity test and pH test. These tests shall be performed once per calendar month when precipitation exceeds 0.25 inches per day or when storm water runoff is noticed leaving a cultivation site.

Stormwater runoff monitoring is required for dischargers that are either tier 1 or tier 2 and fall under moderate-risk or high-risk categories.

Moderate Risk: Any portion of the disturbed area has a slope greater than 30 percent, but less than 50 percent, and all the disturbed area complies with required setbacks to riparian areas.

High Risk: Any Portion of the disturbed area is within the required setbacks to riparian areas.
Remember that the risk classification is not permanent. We can work with you to develop a plan that would reconfigure the site to comply with setbacks. Once we meet the ordinance requirements we can request reclassification of the site.

Stormwater runoff monitoring will be conducted every month where activity is occurring until winterization is complete. Constituents (turbidity & pH) shall be monitored with a calibrated instrument. The samples must be an accurate representation of the site. This means there needs to be multiple samples of multiple runoff locations if applicable. This would give the best representation of the actual stormwater runoff leaving the cultivation site.

A hard copy of the report must be submitted to the State Water Board or Regional Water Board. These agencies may require an electronic submittal of monitoring reports. This would be done using the State Water Board’s CIWQS (California Integrated Water Quality System) program website.

Rebuilding Coffey Park; The Efforts and The Down Falls

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Wed, 26 Sep 2018 03:37:37 GMT

BC Engineering Group has joined the rebuilding efforts of Sonoma County

October 2017 has forever changed Sonoma County as we know it. The Tubbs fire’s damage and resonating effects have reached further than just destroying homes, businesses, and land throughout the County. Flash forward to present day- we have the community rebuilding efforts in the works, but the Community still deals with the agonizing choice of whether to rebuild after losing everything. As if deciding to rebuild isn’t hard enough, now choosing when, or waiting too long to rebuild has consequences in itself.

The Newest Obstacle for Coffey Park

What if your neighbor to the right chose to raise their foundation two feet higher than yours, while the neighbor to the left decided a three-foot increase was what they wanted to do. That creates a grading problem. Many new subdivisions have one civil engineer designing all the grading, drainage, and pad heights, however, Coffey Park has many civil engineers performing design on individual lots, as well as many different builders and their finished design.

Driving through the affected areas of Coffey Park that have started foundations, and even some homes that are already up, have a repeating issue – the FFE (Finished Floor Elevation) is off, in some cases significantly more than their neighbors FFE.

How can this be avoided moving forward? The answer is project engineers, contractors, and builders performing assessments of the surrounding parcels in the field and with the City’s permit records before completing design and moving to construction. BC Engineering Group performs these assessments to ensure their clients receive a design product that can be practically built with the surrounding conditions and with efficient value.

Planning Your Rebuild Development Project

The BC Engineering Group staff currently has over 300 fire-related projects in all stages of the rebuilding process. As a leading Civil Engineering design firm, feel free to reach out to us with any questions you may have regarding the first steps to beginning the new chapter in rebuilding and our efforts to help rebuild the community.

Part 1 of the Cannabis Ordinance Amendments

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 28 Aug 2018 01:34:09 GMT

Part 1 of 2 of the Cannabis Ordinance Amendments

Potential big changes may come for Cannabis Ordinances and may affect project!

The County of Sonoma proposes to amend the Cannabis Land Use Ordinance, Cannabis Health Ordinance, and Cannabis Business Tax Ordinance. These updates will be in two parts. Part 1 of the amendment is geared towards fixing neighborhood compatibility problems that have arisen since the arrival of the Cannabis Ordinance. These updates can have a large impact on your cannabis cultivation plans. Some of the proposed changes could impede some use permits, while having a beneficial impact on others.

The summary of the proposed ordinance amendments and more information can be found here .

The summary of updates are as follows:

Cannabis Permit Requirement (Land Use Table Amendment)

There are 5 policy options. The first option would require a use permit for all sizes of cultivation operations within Non-Industrial Zones (currently cultivation up to 10,000 sqft is allowed with only a zoning permit within LEA and DA lands). The second option would require a use permit for all properties less than 10 acres within Non-Industrial zones. Option three will require a use permit for properties less than 10 acres only within the diverse agricultural zone. The fourth option would require use permits for all cannabis operations within the diverse agricultural zone. The fifth and final option would require a 10 acre minimum parcel size within the diverse agricultural zone.

Inclusion Combining District

There are four proposed policy options. The first would allow cultivation within Rural Residential, Agriculture Residential, Limited Commercial, and Agricultural Services District. The second option is to limit cultivation by planning areas, limit cultivation by area for planned cultivation area, and limit cultivation to properties with historic cannabis use. The third policy option would create a criterion for cultivation including minimum parcel size, proximity to agricultural uses, limitation on size or type of cannabis cultivation. The fourth option is applying standards. These standards apply to residential and commercial. For residential cultivation, the operator shall reside on the property full-time. For Commercial cultivation, it would restrict other cannabis services and restrict visitor serving uses.

Separation Criteria-Setback to Public Parks

There are three options:
The first would be to keep setbacks the same at 1,000 feet from property line. The second would be to increase it to 2,000 feet from property line. The final option would be to allow a reduction of setback from public parks in certain situations.

Measurement of Propogration Area to Support Onsite Cultivation

The planning commission is recommending allowing an additional 25% propagation area. This new addition is to support onsite cultivation, with a use permit.

Term of Cannabis Land Use Permits

Another recommended amendment from the planning commission is to extend the term of cannabis permits. This would increase the cannabis use permits from 1 year to 5 years. This would also increase cannabis zoning permits from 1 year to 2 years.

County of Sonoma to Open Resiliency Permit Center

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Wed, 28 Mar 2018 14:13:13 GMT

Resiliency Permit Center is exclusively dedicated to assist survivors of the fire rebuilds

The County of Sonoma has established a Resiliency Permit Center exclusively dedicated to assisting survivors of the fires to rebuild their homes. The center has been open since February 13th and has helped expedite the permitting process. The Resiliency Permit Center is located adjacent to the existing Permit Sonoma offices at 2550 Ventura Avenue in Santa Rosa. Having the Resiliency Permit Center means a few different benefits for fire victims.

Reduced Processing Time - Applications will have an expedited processing time of five business days or less for plan checks, with three business days for rechecks.

Reduced Permit Fees - Rebuild permits will have a reduced permit fee schedule reflecting reduced work due to the already developed nature of sites with driveways, wells, septic systems, and other infrastructure.

What if you already submitted and payed fees?

Fire survivors using Permit Sonoma services at the regular fee schedule will be refunded the difference.

Planning your rebuild Project

The BC Engineering Group staff has developed numerous fire rebuild plan sets and can guide you through every step of the rebuild permitting process. As a leading civil engineering design firm, feel free to reach out to us with any questions you may have regarding the new Resiliency Permit Center and its resources.

Cannabis Cultivation Site Plan

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Wed, 14 Mar 2018 18:10:38 GMT

Sonoma County Cannabis Cultivation Site Plan Requirements

The first step in legal cultivation of cannabis in Sonoma County is getting your permits. In order to get these permits you will have to be dealing with the County of Sonoma. Here at BC Engineering Group, we are committed to making that process as smooth as possible. We know all the requirements and are very familiar with the permitting process.

Cannabis cultivation sites include locations where cannabis is planted, grown, harvested, dried, cured, graded, or trimmed. Those interested in operating a cannabis cultivation site will require a site plan.

Sonoma County Site Plan Requirements :

Both a 24 in. x 36 in. or 11 in. x 17 in. site plan and one reduced site plan (8 ½ in. x 11 in) is required by the County of Sonoma. The reduced site plan must clearly depict the information shown on the full-sized site plan. Preparation of the site plan by a professional draftsperson, architect, or engineer is strongly recommended. If the existing site is to be greatly modified by the proposed project (removal of existing buildings, vegetation, etc.), both an Existing Site Plan and a Proposed Site Plan are required.

All Site plans shall meet the Minimum Standard Site Plan Requirements and include the following:Cultivation area(s), which shall contain all plants, both mature and immature.

Propagation area(s).
Storage area/structure for pesticides and other agricultural chemicals, as well as fuels.
Areas where composting of green waste will occur, if applicable.
Holding area for Cannabis scheduled for destruction.
Area(s) and structures where Cannabis will be processed, if applicable.
Area(s) for non-compostable refuse.
Area(s) where harvested Cannabis will be stored.

Septic Regulations for Rebuilding After the Sonoma Complex Fire

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Thu, 22 Feb 2018 18:29:12 GMT

Fire Damaged Septic regulations and permitting

Many properties damaged or destroyed in the Sonoma Complex Fire were served by septic systems. These parcels must have their septic system(s) inspected in order to connect rebuilt dwellings to the onsite sewage disposal system. The County of Sonoma is allowing for structures to be rebuilt, on Sonoma Complex Fire damaged parcels, without having to upgrade the septic system to current County of Sonoma septic standards. This means many homes served by a septic system can be rebuilt with little to no septic repairs being made. The existing septic system must meet County of Sonoma Class III septic system standards.

What septic clearance do I need to rebuild?

Properties served by septic systems must obtain clearance prior to rebuilding. The existing septic system must be inspected by a qualified professional; which includes Civil Engineers, Environmental Health Specialist (REHS), or a Contractor with an “A”, “C-36”, or “C-42” license. The qualified professional must complete the Septic System Evaluation Form for Rebuilds and Temporary Housing (Sonoma Complex Fire) Document and provide a 1”=20’ scaled Site Map depicting the septic system location. If the existing permit does not contain a map drawn to the required scale, a plan showing the system location must be produced by the Qualified Professional.

Is my system acceptable for reuse (reutilization)?

Most septic systems will be able to be reutilized as is or with minor modifications. The septic system must have a two compartment septic tank made of approved materials and a dispersal area leach field. This means properties served by cesspools and systems with no septic tank will need to be upgraded in order to rebuild dwellings on the parcel. Basic sanitary fixtures must exist or be installed. The septic system must meet County of Sonoma Class III standards.

The existing septic system must be permitted or pre-code in order to be reutilized. Systems installed without benefit of permits will not be eligible for reuse until required permits are obtained.

What if my system requires minor repairs?

The County of Sonoma is allowing many minor repairs to be performed without permits. These include system components such as riser lids, monitoring wells, valve boxes, etc. Approved repairs made without permits shall be listed on the Septic System Evaluation Form for Rebuilds and Temporary Housing (Sonoma Complex Fire) Document by the Qualified Professional.

Repairs to the dispersal area (leach field), electrical components, or other non-permit exempt portions of the septic system must have a permit obtained prior to construction. Please consult BC Engineering Group to determine if you require a permit to perform necessary septic system repairs.

Can I hook up an RV or Travel Trailer to my septic system?

Once your septic system is inspected by a Qualified Professional and deemed acceptable for reutilization, a RV or Travel Trailer can be temporarily connected to it. A permit is required to connect a RV or Travel Trailer to the existing septic system.

What if I want to add bedrooms to my new dwelling or build a new accessory dwelling unit?

In order to increase the bedroom count of the prior structure, a new septic system will likely be required. This will require the parcel to go through the standard soil testing, design, and permitting process, as required by the County of Sonoma OWTS Manual.

My house survived but my septic system was damaged by the fire, can I live in the dwelling?

All dwellings must have an approved and functioning septic system in order to be occupied. This means that regardless of the structure’s condition, the building(s) cannot be occupied until septic clearance is granted. If the dispersal area (leach field) is damaged or destroyed, but your septic tank is undamaged, or minor repairs are completed, the existing septic tank can be used as a temporary holding tank. This requires a permit to be obtained and a pumping contract to remain in effect until the dispersal area is repaired.

We Can Help!

If you’re planning to rebuild on a Sonoma Complex Fire damaged parcel, contact BC Engineering Group , we know the applicable laws and ordinances, and have been actively involved in septic policies for fire parcels as they have been developed.

California Public Water System Permitting

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 13 Feb 2018 18:25:16 GMT

Public Water System Permitting in California

What is a public water system?

A public water system is defined as a system that provides water for human consumption to 15 or more connections or regularly serves 25 or more people daily for at least 60 days out of the year. There are three types of water systems:

Community – Such as City, County, regulated utilities, regional water systems, and small water companies and districts where people live.
Non-transient non-community – Typically schools and businesses that provide their own water. A consistent group of individuals consumes the water, but do not reside there.
Transient non-community – Includes entities like gas stations, restaurants, parks, etc., that provide their own potable water source. Most individuals who consume the water do not reside or regularly spend time there.

Public water system permitting

Public water systems are required to have domestic water supply permits through the State Water Resources Control Board. For new water systems, the first step in the permitting process is to explore consolidation with an existing water system in the vicinity and submitting a preliminary technical report to the State. Most times, consolidation is not feasible as either the cost is impractical or the existing system prefers not to consolidate.
Once it is determined that a new water system permit will be required, an application is submitted to the State, which then generates a Permit Application Requirements Checklist, which identifies all required documentation to receive the water supply permit. Each checklist is unique and applicable to the specific project. Required documentation includes, but is in no way limited to the following:

Well capacity and estimated demand calculations
Well pump tests
Documentation of well features
As-built and proposed mapping
Raw water monitoring
Water system operator information
Operations plan
Emergency plan

O ur office frequently works with the State and certified water system operators to develop and submit all required documents to permit new water systems, and to amend existing water permits to add additional wells, treatment, or other features.

Septic Inspections vs. Findings Reports

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Mon, 10 Apr 2017 16:53:16 GMT

What is the difference between septic inspections and septic findings reports?

Septic Inspection vs. Findings Report
Are you looking to buy a home in Sonoma County , or start that remodel on your Sonoma County home that you’ve always wanted? If you answer yes to one of these then we’ve got some info that will help walk you through the process of knowing the difference between a septic inspection vs. a findings report.

Why would I GET a septic inspection?
If you’re looking to finally get that dream home you’ve always wanted, or maybe just looking for an investment opportunity, a septic inspection should be one of the first things you obtain. A septic inspection will evaluate how well your septic system is working, or in some cases not working. Depending on the property in question, if you have a septic system that is not working properly, you could be in for some huge unforeseen costs in the future. So, if you’re looking to buy, and it’s in a rural area, get a septic inspection!

When would I NEED a finding report?
If you plan to modify a home that you’re looking to buy, or want to remodel your existing home, you’ll need to obtain permits. As a part of the permitting process, you’ll be required to provide an assessment report on the septic system; this assessment report is formally called a findings report. The findings reports are prepared by a Licensed Professional Engineer or Registered Health Specialist.

Depending on the level of modifications you intend to make to the property, your septic system will need to meet a certain level of classification. The findings reports will provide an opinion of the classification of the septic system; the County will review this information to verify the septic system complies with the level of improvements being made to the property.

If you do not have a proper classification with your septic system, you may not be able to get your project off the ground. Many people don’t realize the importance of their septic system and what it could mean for their long term plans for the property or development goals.

We Can Help!
BC Engineering Group has extensive experience with both septic inspections and findings reports. For more details about either of these or if you just have some questions, please contact BC Engineering Group today (707) 542-4321. Like us on Facebook and LinkedIn , and subscribe to our blog .

Septic Tank Effluent Pump (STEP) Systems

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Fri, 07 Apr 2017 02:53:25 GMT

Sewage pumps to connect to City Sewers

When Are STEP Systems Used?
Most sewer customers’ household waste goes directly into a gravity sewer collection system and is then transported to the wastewater treatment plant for processing. Homeowners not connected to sewer are typically served by an onsite septic system. When a sewer connection becomes an option for homes on septic, a Septic Tank Effluent Pump (STEP) system can be utilized to make the conversion to sewer. Each individual STEP system includes a septic tank, pump and control panel. The septic tank allows solid and liquid wastes to separate, preventing the solid waste from making its way out. When a gravity line is not sufficient enough for wastewater to be distributed, the pumps in these systems help to push the effluent (liquid waste) to the sewer system.

What Is The Difference Between a STEP System And A Grinder Sump System?
STEP systems and Grinder Sump systems are similar in the sense that they both have a common goal of moving wastewater. Both work to minimize solid waste build up and are pump assisted. In a STEP system, as waste is sent out of the building, it makes its way into a septic tank. In the septic tank, the solid waste settles to the bottom, allowing the effluent to then make its way into the liquid only side of the tank. Once the effluent makes it into the liquid side, it is then pumped out to the sewer. This system’s pump is controlled by a combination of floats. As the fluid level in the tank rises, the floats will then activate the pump, sending the effluent to its proper destination. This pump is hooked to an alarm system. This alarm system is triggered by the floats if the effluent level rises too high.

Grinder Sump systems do not require a septic tank as needed for STEP systems. In this case, waste travels into a pump chamber, where the grinder pump is housed. As waste flows into this chamber, the pump grinds up and pumps out the solid waste, allowing it to flow freely with the liquid waste to a sewer main. These pumps are also hooked up to an alarm system, which like the STEP system, if the pump fails and sewage backs up in the chamber, the floats will trigger the alarm as a warning.

What Properties Utilize STEP and Grinder Systems?
For customers needing to connect to a sewer service, and have existing septic systems, both of the systems discussed are an option. By adding a pump to the existing septic tank, or installing a grinder sump, they will help get your wastewater to the sewer system.

We Are STEP System Experts!
BC Engineering Group has extensive experience with both STEP Systems and Grinder Systems. For more details about either of these or if you just have some questions, please contact BC Engineering Group today (707) 542-4321. Like us on Facebook and subscribe to our blog .

New Laws Affecting Second Dwelling Units

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Fri, 24 Mar 2017 14:11:14 GMT

Second Dwelling Units and Guest House Regulation Changes

What Has Changed?

In September 2016, three laws were signed by Governor Brown and included Senate Bill 1069, Assembly Bill 2406, and Assembly Bill 2299. These laws went into effect in the very recent past and have to do with the creation of second dwelling units. The term second dwelling unit is being replaced with accessory dwelling units and junior accessory dwelling units. To comply with these new State laws, the County of Sonoma passed Ordinance No. 6191. The County’s ordinance provides local compliance and is consistent with the Sonoma County General Plan. The ordinance shall be followed by individuals intending to develop accessory dwelling units and junior accessory dwelling units.

Permits Required for Accessory Dwelling Units

Development of an accessory dwelling unit requires a zoning permit from the County of Sonoma and compliance with all applicable codes (building, fire, septic, water, etc.). Junior accessory dwelling units will not require a zoning permit or compliance with most codes, and only a building permit is required, as the junior accessory dwelling units are typically considered a portion of an existing residence that is being converted.

What Sizes Can Accessory Dwelling Units Be?

Junior accessory dwelling units cannot exceed 500 square feet in size and must be contained within the walls of an existing legal dwelling. The junior accessory units can have a kitchen facility and may share bathrooms with other units. Accessory dwelling units cannot exceed 1000 square feet in size and cannot be larger in size than the main dwelling unit. Accessory dwelling units can be detached from the main dwelling unit.

We Can Help!

If you’re planning to develop an accessory dwelling unit, contact BC Engineering Group, we know the applicable laws and ordinances, and have extensive experience with these units. For more details about accessory dwelling units and the new regulations, please contact BC Engineering Group today at (707) 542-4321. Like us on Facebook and subscribe to our blog .

Vineyard Development in Sonoma County

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Mon, 20 Mar 2017 21:51:26 GMT

Vineyard Development in Sonoma County

Vineyard Development
Permits are required from the Sonoma County Agricultural Commissioner’s Office for new vineyards and replanting of existing vineyards. Depending on site slopes and soils, vineyard development projects are separated into two types, Level 1 and Level 2.

Level 1 submittals for vineyard development are fairly straight forward and require a USGS Quad Map exhibit, aerial photo of the proposed vineyard development, completed application, and a biological assessment of the project area performed by a biologist. Having the biological assessment performed is typically the first step so that any sensitive areas can be avoided during the plan development phase.

Level 2 submittals are much more involved and have requirements in addition to the submittal documents for a Level 1 vineyard. All Level 2 projects require an erosion control plan developed by a civil engineer. Level 2 projects also require an analysis of the project drainage to determine if pipe systems or retention basins should be considered for the project. Lastly, if trees are proposed to be removed as a part of the project, soil loss calculations must be performed to verify that there will be no increase in soil loss in the post development condition.

Percolation Testing for Septic Development – Sonoma County

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Tue, 14 Mar 2017 21:48:21 GMT

Sonoma County Percolation Testing for Septic Development

Why Test Soil Percolation Rates?

Percolation testing determines the absorption rate of soil where sewage is proposed for disposal by a septic system. Design of a leach field or septic system requires the percolation rate of the soil where the system will be installed. The test is performed by applying water to test holes in the proposed leach field area and recording the rate of percolation for each test hole. A percolation test is typically performed after suitable soils have been located on site by a soil investigation.

How Is A Percolation Test Performed?

A conventional percolation test typically consists of the following steps:

Locate soils that are suitable for septic development and verify with a County Sanitarian. This process includes reviewing soil test pits to evaluate the subsurface soils and conditions. The presence of groundwater or plastic soils, like clay, are typically considered limiting conditions.
Percolation test holes are installed at various depths depending on soil conditions observed.
Perforated pipes are installed into each percolation test hole and surrounded at the bottom of the pipe with 12” of pea gravel.
The percolation test holes are pre-soaked with water the day prior to the percolation test. This is to provide the soils with a typical level of saturation.
The day of the percolation test, which follows the day of pre-soaking per step #4, each pipe is filled with water to the pea gravel and the time of filling is recorded for each hole.
After one hour has passed, the water level is measured from the top of the pipe and recorded. This process is repeated for six hours; refilling the pipe to the pea gravel whenever the water level drops to within two inches from the bottom of the test hole. If a test hole runs dry after the first hour, refill to the pea gravel and take readings every ten minutes for two hours, also refilling the pipe to the pea gravel whenever the water level drops to within two inches from the bottom of the test hole.
Calculations for the percolation rate take place after the test is run. Divide the time intervals by the corresponding drop in water level to calculate the percolation rate in units of minutes per inch for each hole.

Generally, percolation tests in alluvial soils, like sandy loam, will have much faster rates of percolation than plastic soils like clay. The calculated average percolation rate is a critical parameter in the design of a septic system, which is the next step of the process for development of a septic system.

Developing Near California Tiger Salamander Habitat

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Mon, 06 Mar 2017 21:04:41 GMT

California Tiger Salamander Mitigation for Land Development

Where Do California Tiger Salamanders Live?
Sonoma County is home to the California Tiger Salamander (CTS) and several protected plant species (listed plants). Though we are happy to host and conserve lands for endangered species, this can provide some challanges to land development in CTS breeding zones and around adult CTS occurances. Mitigation for endangered species is essential to keeping the CTS safe during continual development in Sonoma County

Mitigating for Impacts to California Tiger Salamander Habitat?
Being within a conservation area doesn’t change the parcel’s zoning or land use designation, nor does it add development restrictions. Rather it adds an extra step of mitigation to the parcel’s development, without changing its potential. Mitigation must be done for all hardscape (roads, compacted gravel surfaces, buildings, etc.) work proposed. For linear projects (utility lines, pipelines, fences, etc.) the mitigation area consists of the land disturbed by the construction.

Mitigation for projects is usually performed by purchasing credits from a mitigation bank. There are two types of mitigation banks; preserve mitigation bank and wetland mitigation banks. Mitigation banks are designed to create habitats large enough for multiple site mitigation. These banks sell mitigation credits to satisfy the mitigation requirements for development.

The appropriate type and amount of credits must be purchased to satisfy the mitigation requirements for the specific site development. The proximity to CTS breeding sites and adult CTS occurrences determine the ratio of mitigation credits that must be purchased.

Per the Santa Rosa Plain Conservation Strategy the following mitigation is required:

Mitigation of 3:1 – For projects that are within 500 feet of a known breeding site.
Mitigation of 2:1 – For projects that are greater than 500 feet, and within 2,200 feet of a known breeding site, and for projects beyond 2,200 feet from a known breeding site, but within 500 feet of an adult occurrence.
Mitigation of 1:1 – For projects that are greater than 2,200 feet, and within 1.3 miles of a known breeding site.
Mitigation of 0.2:1 – For projects in areas shown as “Potential for Presence of CTS” or “Potential for Presence of CTS and Listed Plants.”

Surveying for Habitat?
If a project falls into a mitigation area, a survey to determine if CTS or listed plants are present may be performed to determine if mitigation is necessary. This process may take up to two years to complete. If CTS or listed plants are present, then the appropriate mitigation ratio will apply. If no CTS are found during the survey, then mitigation shall not be required.

BC Engineering Group Is Here To Help.
Mitigation ratio determination and the requirement there of can be difficult to determine. Please contact BC Engineering Group, Inc. for more information about whether your project requires mitigation, and if so, how to proceed.

Story Poles and Their Purpose

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Mon, 20 Feb 2017 21:00:06 GMT

Proposed building story poles for construction

What are Story Poles?

Story poles are typically constructed out of wood, pipe, or steel posts and stick up vertically from the ground surface. Story poles are often used to assist in the construction design process or may be required by a local agency prior to project approval. They help to represent the silhouette of a proposed structure or possible addition to an existing building. They are used in both residential and commercial developments, usually within coastal and mountain view areas where there may be view preservation concerns.

How Can Story Poles Benefit My Project?

Once the story poles have been installed to their specified location and height, their visual aid can be used to show the impact the design will have on the neighboring views. Additionally, by showing the elevation and ridgelines of a proposed project, it’s possible to minimize the impact a project will have on the surrounding environment. After installation you can see how the natural landscape will interact with the proposed project, making it possible to alter the design to accommodate for existing tree heights and how to best fit the structure to the environment. As the design process evolves, the story poles can be raised or lowered to mirror the changes made to the overall project.

How Quickly Can They Be Installed?

Installation of story poles can be done in just a matter of days. Once the poles have been installed, they can be used for days or left up for months. After their visual aid is no longer needed, the poles can be removed and the surrounding area returned to its normal state.

We Can Help!

BC Engineering Group has extensive experience with the installation of story poles. For more details about story poles and how they can assist you in the design of your project, please contact BC Engineering Group today (707) 542-4321. Like us on Facebook and subscribe to our blog .

How to Repair Streambank Erosion, Legally!

Wed, 15 Feb 2017 20:38:29 GMT

Creek and Riverbank Erosion Repair

What is Streambank Erosion?

The erosion of creek banks and stream edges is a result of Mother Nature’s winter acts and is completely natural. As winter storms dump large amounts of rainfall, creeks and streams swell in size, and the forces of these large volumes of water are no match for saturated soils sitting on the edge of the waterways. The constant flowing water force and heavy rainfall against the exposed soil causes it to erode and fall into the waterways. Once a stream bank begins to erode and lose vegetation, such as trees and shrubs, the loss of soil can accelerate very quickly.

Why is Streambank Erosion Bad?

When a stream or creek bank erodes, property is literally eaten away by the watercourse, leaving behind a void or pit when the water flows subside. This loss of land can create property and environmental damage. Valuable land including vineyards, buildings, and the like can be swept downstream with the soil as it erodes, creating financial damage to properties. Sediment and debris from a bank eroding can create environmental issues for biological habitats or block waterways and lead to flood danger.

Addressing Streambank Erosion

Erosion of creek or river banks can be stopped, repaired, or mitigated with conventional earthwork and construction practices. These restoration practices typically include installation of in-channel revetment, such as large rocks or retaining walls to prevent water forces from encountering erosion susceptible soils, and drainage run-on diversion to prevent saturated soil conditions.

Fixing It Right, and Legally!

Most stream bank erosion has environmental and safety concerns associated with it. Because of this, any restoration of erosion in watercourses must involve the agencies with jurisdiction of the elements affected. These agencies typically include:

California Department of Fish and Wildlife
United States Army Corps of Engineers
California Regional Water Quality Control Board
Local Permitting Agency (County or City)

Obtaining permits to restore stream bank erosion can be a lengthy process, however, in critical situations these agencies typically allow for an emergency permitting option. To avoid potentially major legal issues, stream bank repairs should always be performed with the oversight of governing agencies and consultants. Additionally, the permitting requirements can vary drastically from project to project.

Wastewater System Planning In Sonoma County

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Wed, 31 Aug 2016 19:26:06 GMT

Wastewater System Planning In Sonoma County

Many projects in Northern California, including Sonoma and Napa Counties, require septic systems to serve residential and commercial buildings. Typically, properties that lie outside of City limits (in a County jurisdiction) only have the option of septic systems for generated wastewater disposal. The size and type of septic systems often determine the capacity of a property’s development potential.

Step one on any project without sewer is determining septic system capacity and location. Many factors must be taken into account when designing a septic system; soil texture, soil depth, site topography, location of water sources, ground water levels, parcel size, and many more. The sensitivity of where septic can be located often determines where buildings can be placed on a property, so as to avoid the septic suitable areas.

Septic system capacity is important to know prior to final architectural plans. If septic suitable space is limited, the septic system capacity may determine the total number of bedrooms or patron capacity of the structure(s) being proposed. Several engineered septic system solutions exist to maximize the capacity of the septic system. At BC Engineering Group we work with our clients to determine the most cost efficient septic solution to meet their project scope.

On developed properties the existing septic system and septic expansion capability determines the size and type of prospective future development or existing structure modifications. Developed properties must meet the appropriate septic codes to remodel, rebuild, or add additions to the existing buildings. The future ability to construct accessory buildings, such as second units, guest homes, and workshops is determined by the condition and capacity of the existing septic system. Depending on the development desires of the client, the septic system may need to be modified or redesigned to achieve the required septic system classification and capacity.

The property’s septic system also determines the size of the additions and remodels. For example, in the County of Sonoma an existing system with low classification may only be able to add additions up to 640 sq-ft; where those with higher classification do not have a size limit for additions.

Prior to property transactions it is important to know the future septic system possibilities and classification of the existing septic system. When you buy a property, you want to make it your own and add that personal touch, the septic system often determines whether you can make the desired customization. BC Engineering Group can help you determine whether your future property desires are achievable.

Know where your wastewater is going before starting a project so you don’t flush money away. Proper site development planning can save you money, time, and stress. Let BC Engineering Group help you plan and complete your project in the most efficient manner.

State Water Board – Site Management Plan for Commercial Cannabis

jacob@fitzdesignz.com (Jacob Fitzpatrick) — Sat, 09 Nov 2013 04:43:07 GMT

Commercial Cannabis Site Management Plan

The State Water Resource Control Board approved the Cannabis General Order last year on October 17th. The General Order covers guidelines for cannabis cultivation, general waste discharge requirements, and waiver of discharge requirements for discharges of waste associated with cannabis cultivation activities. To obtain a license from the California Department of Food and Agriculture, one must be in compliance with the cannabis policy. An important aspect of becoming compliant is submitting a Site Management Plan.

What is a Site Management Plan?

A Site Management Plan is a list of activities and best management practices that a cannabis cultivation site intends to follow as they conduct their business operations. The goal of a Site Management Plan is to prevent storm water pollution and erosion control. An outline of a Site Management Plan is found in the General Order, as Attachment D. This outline shows the requirements that need to be addressed in the Site Management Plan.

The first step is to identify what type of discharger category the site falls under; Tier 1 or Tier 2.

Tier 1: Having a disturbed area greater than 2,000 square feet but less than 1 Acre (43,560 square feet).

Tier 2: Having a disturbed area equal to or greater than 1 Acre.
The second step is to identify your Risk Designation; Low, Moderate, or High Risk:

Low Risk: The disturbed area has a slope less than 30 percent and all of the disturbed area complies with required setbacks to riparian areas.

Moderate Risk: Any portion of the disturbed area has a slope greater than 30 percent and all of the disturbed area complies with the required setbacks to riparian areas.

High Risk: Any Portion of the disturbed area is within required setbacks of riparian areas.

Understanding and determining your Tier and Risk Designation is a very important part of the Site Management Plan. This will dictate what is required in the Site Management Plan and whether or not other reports will be required upon submittal.

The Site Management Plan covers multiple aspects of stormwater, sediment control, and erosion prevention. The plan needs to show how a site will prevent stormwater pollution and the best practical treatment or control (BPTC) measures that will be implemented to deal with waste discharge from the site. The discharger information must include; Sediment Discharge BPTC Measures, Fertilizer and Pesticide BPTC Measures, Petroleum Product BPTC Measures, Trash and Domestic Wastewater BPTC Measures, and Winterization BPTC measures.

If this information seems like a lot, don’t worry as we are here to help!
