Calichi Design Group is a civil and stormwater engineering firm with offices in Oakland, CA. We’ve delivered site civil engineering, SWPPP preparation, fire flow analysis, and dry utility consulting for residential, commercial, industrial, and institutional projects throughout Fremont and Alameda County since 2009. Our proposals are fixed-fee and specific to your site.
Civil Engineering in Fremont, CA
Fremont is Alameda County’s largest city by area and one of the fastest-growing in the Bay Area. The development pipeline reflects that growth: EV manufacturing and semiconductor campus expansions on the industrial side, multi-family infill near Warm Springs and Fremont BART stations on the residential side, and a steady flow of commercial and retail projects across the city. Each of those land uses brings its own permitting track, its own stormwater classification, and its own utility coordination requirements.
We work with developers, school districts, and commercial property owners on Fremont civil engineering projects from entitlement documents through construction support. Our work in Fremont typically involves coordinating with the City’s building and planning divisions, the Alameda County Water District (ACWD) for water connections and fire hydrant capacity, and the Alameda Countywide Clean Water Program for C.3 stormwater compliance.
Fremont’s topography varies from the flat bay plain near the Warm Springs BART station to steeper terrain in the Mission Hills and Niles communities. That variation matters for drainage design, bioretention sizing, and infiltration feasibility, and it’s something we account for based on actual site conditions rather than regional assumptions.
SWPPP and C.3 Stormwater Design in Fremont
Fremont is a member agency of the Alameda Countywide Clean Water Program, which implements the San Francisco Bay Regional Water Quality Control Board’s Municipal Regional Permit (MRP) for Alameda County. That means stormwater management obligations for development projects in Fremont are governed by the Program’s C.3 Technical Guidance Manual.
Projects creating or replacing 10,000 square feet or more of impervious surface trigger C.3 post-construction stormwater controls. Projects with 22,500 square feet or more of regulated impervious surface also trigger hydromodification management requirements. Projects disturbing one acre or more of soil require a Stormwater Pollution Prevention Plan (SWPPP) under the State’s Construction General Permit.
We prepare both the SWPPP and the C.3 post-construction hydromodification analysis as a coordinated package. Reco Prianto holds active QSD and QSP certifications (Qualified SWPPP Developer and Practitioner), so we prepare, certify, and submit the SWPPP without a subcontractor step. For C.3 facilities, we size bioretention cells, flow-through planters, and permeable pavement sections based on the project’s regulated impervious area and local soil infiltration rates. We integrate those facilities into the grading and drainage design rather than treating them as a late-stage add-on.
In Fremont’s Warm Springs district and the Irvington area, high groundwater depth can limit infiltration feasibility. We assess that condition at project startup and choose facility types accordingly. If a lined bioretention cell is necessary, we size it to the non-infiltrating design case in the C.3 Technical Guidance Manual.
Fire Flow Studies for Fremont Projects
A fire flow study is required by the City of Fremont for new construction, additions, and changes of occupancy that affect the fire suppression demand. The study confirms that the municipal water distribution system can deliver the required flow rate at adequate residual pressure at the building’s point of connection under simultaneous maximum-day demand conditions.
In Fremont, water service is provided by the Alameda County Water District (ACWD), which serves Fremont, Newark, and Union City. ACWD maintains the distribution mains, fire hydrant locations, and system pressure data across the city. A fire flow study for a Fremont project involves reviewing ACWD’s system data, calibrating a hydraulic model to the local distribution network, and confirming that available flow and pressure meet the fire authority’s minimums at the project site.
The required flow rate depends on building occupancy type, construction classification, and square footage as defined in the California Fire Code. When the study finds that the existing system falls short of the project’s demand, the remediation options are a water main extension, an on-site fire storage tank and booster pump system, or a project design modification that reduces the required fire flow. We work through those options with the project team and present findings in the report format the City requires for plan check.
Site Civil Engineering, Grading, and Utility Coordination
A typical Fremont civil engineering package covers grading and drainage design, utility layout and dry utility coordination, ADA path-of-travel improvements, and encroachment permit applications with the City’s Public Works division. Industrial and logistics projects in the southern Fremont corridor near Interstate 880 often require coordination with Caltrans on access points and right-of-way improvements, and we handle those encroachment permits as part of the civil scope.
For school and institutional projects within Fremont Unified School District or Mission Valley Regional Occupational Program territory, the Division of State Architect (DSA) reviews the civil drawings. We have direct DSA experience on East Bay school projects and we format our submittals to meet DSA’s completeness requirements at first submittal, which keeps the review timeline predictable.
Dry utility coordination in Fremont means managing relocations and new service installations with PG&E, AT&T, Comcast, and other franchise utilities. We start that process early so the underground utility design doesn’t conflict with grading or paving schedules. See our dry utility consulting page for detail on how we structure that process.
Fremont Agencies and Jurisdictions We Coordinate With
City of Fremont
The City of Fremont issues building permits, grading permits, encroachment permits, and subdivision map approvals. Site plan review, planning entitlements, and building permits often run on parallel tracks for larger projects. We prepare the civil documents for both tracks and respond directly to plan check comments from the City’s reviewers, which keeps the response cycle tight.
Alameda County Water District (ACWD)
ACWD is the retail water provider for Fremont, Newark, and Union City. Any project requiring a new water service connection, fire hydrant installation, water main extension, or fire service line in Fremont goes through ACWD. We prepare water improvement plans to ACWD’s published standard drawing requirements and coordinate plan check and inspection through ACWD’s Development Services group. The fire flow study references ACWD’s system data and is coordinated with both ACWD and the City’s fire authority.
Alameda Countywide Clean Water Program
Fremont is a member of the Alameda Countywide Clean Water Program, which administers C.3, C.6, and hydromodification management requirements for Alameda County under the Regional Water Quality Control Board’s MRP. The Program publishes the C.3 Technical Guidance Manual that governs stormwater facility sizing and operation and maintenance requirements for post-construction controls. We use that manual as the design standard on every Fremont project that triggers C.3 requirements.
Projects Near Fremont, CA
We reference only confirmed projects from our portfolio. The following projects in the East Bay region reflect the project types and regulatory environment we navigate regularly in Fremont:
- Fremont High School Net-Zero Campus (Oakland, CA): Civil, grading, drainage, and stormwater design for a nine-building, 190,000 square foot campus replacement for Oakland Unified School District. DSA-reviewed. The project type, combining a dense urban site with stormwater control measures and school district permitting, directly parallels institutional and school projects in Fremont Unified territory.
- Dublin Transit Center (Dublin, CA): New construction of a 516-space, 5-story parking structure on a 2.5-acre site. Dublin is immediately adjacent to Fremont’s eastern neighborhoods, and transit-adjacent development of this scale reflects the project types common near Fremont and Warm Springs BART.
- KIPP Bridge Academy (Oakland, CA): Civil design for a two-story charter school in Oakland, including grading, storm drainage, stormwater control measures, and utility plans.
- 57-Unit Affordable Housing Complex (Oakland, CA): Civil entitlement documents and full construction documents for a 57-unit mixed-use affordable housing project at 95th and International Boulevard, including City of Oakland and Caltrans encroachment permits.
We also served as Engineer of Record on the Chase Bank West Coast Expansion Program, delivering civil engineering, stormwater design, and permitting for over 100 retail banking locations across California, Nevada, and Arizona, including multiple Bay Area sites with C.3 obligations and ADA upgrade requirements.
Frequently Asked Questions: Civil Engineering in Fremont
When does a Fremont project require a SWPPP?
A SWPPP is required under the California State Construction General Permit when a project disturbs one acre or more of soil during construction. For projects below that threshold, Fremont’s local stormwater permit requirements may still require erosion and sediment control plans as part of the grading permit package. We assess the applicable permit threshold at project startup and prepare the appropriate document for the scope.
What fire flow is typically required in Fremont?
Required fire flow in Fremont depends on the building’s occupancy type, construction type, and total floor area under the California Fire Code. Light commercial projects often require 1,500 gallons per minute. Larger or higher-hazard occupancies can require 3,000 gallons per minute or more. We calculate the project-specific requirement as part of the fire flow study and model the ACWD distribution system to confirm available capacity at the project’s hydrant connection.
What triggers C.3 stormwater requirements in Fremont?
Projects creating or replacing 10,000 square feet or more of impervious surface trigger C.3 post-construction stormwater controls under the Alameda Countywide Clean Water Program. Projects with 22,500 square feet or more of regulated impervious surface also trigger hydromodification management analysis. The precise thresholds and facility sizing procedures are in the C.3 Technical Guidance Manual. We apply that manual on every qualifying Fremont project.
