Civil Engineering in San Ramon, CA
San Ramon is one of Contra Costa County’s most active development markets. The San Ramon Valley has sustained corporate campus expansion, residential infill, mixed-use redevelopment, and new commercial construction steadily, and each project that goes through the City of San Ramon’s permit process needs grading plans, drainage design, stormwater controls, fire flow analysis, and utility coordination that satisfy the city’s Engineering Division and Contra Costa County’s stormwater program. Calichi Design Group handles that work across California, and we’ve been operating in the Bay Area since our founding in Oakland in 2009.
We carry active PE licensure in California and QSD/QSP credentials for SWPPP preparation, so we handle the full civil and water engineering scope in-house. Our fixed-fee proposals give San Ramon clients cost certainty before any work starts.
What We Do in San Ramon
Civil engineering in San Ramon means navigating Contra Costa County’s regulatory framework: the city’s own plan check, the Contra Costa Clean Water Program for stormwater, and coordination with the utilities that serve the San Ramon Valley. Our site civil engineering scope in San Ramon covers:
- Grading and drainage design: Cut and fill analysis, finished grade, storm drainage routing, inlet sizing, and outfall design that meets city standards and the local drainage requirements.
- SWPPP preparation: Stormwater Pollution Prevention Plans prepared by a licensed QSD for projects disturbing one or more acres, including Rain Event Action Plans and BMP specifications for Contra Costa County construction inspectors.
- C.3 stormwater controls: Low Impact Development design, bioretention sizing, and Stormwater Control Plans that comply with the Contra Costa Clean Water Program’s C.3 Guidebook and the San Francisco Bay Regional Water Quality Control Board’s Municipal Regional Permit.
- Fire flow studies: Water supply analysis and fire flow calculations for commercial, industrial, multifamily, and institutional projects, coordinated with the city’s plan check and the fire authority having jurisdiction.
- Dry utility design: Joint trench design and franchise utility coordination for PG&E, telecommunications providers, and others. See our full dry utility consulting scope.
- Right-of-way and encroachment permits: Curb, gutter, sidewalk, driveway, and street improvements that require the city Engineering Division’s review and permit issuance.
- Water and sewer design: Service laterals, meter sizing, pressure analysis, and backflow prevention sizing coordinated with the water purveyor serving the project location.
- Site entitlement support: Feasibility assessments and preliminary civil plans that support planning applications before construction documents begin.
Agencies We Coordinate With in San Ramon
City of San Ramon, Permit Center and Engineering Division
Development permits in San Ramon run through the city’s Permit Center, which handles building permits, engineering inspections, and land use permits. The Engineering Division reviews grading, drainage, and right-of-way improvement plans against the city’s standard specifications. Projects that include public improvements, drainage facilities, or significant site alterations need to be coordinated with Engineering early so plan check comments don’t add schedule. We organize our submittals for San Ramon’s review process and track comments through to approval and permit issuance.
Contra Costa Clean Water Program
San Ramon is in Contra Costa County, so stormwater compliance for development projects runs through the Contra Costa Clean Water Program (CCCWP). The CCCWP implements the Municipal Regional Permit issued by the San Francisco Bay Regional Water Quality Control Board and has published a C.3 Guidebook that governs Low Impact Development requirements for Contra Costa County jurisdictions. Development projects that create or replace significant impervious area need to design and size on-site stormwater treatment and hydromodification controls. We prepare the Stormwater Control Plan that satisfies the CCCWP’s requirements and supports the city’s post-construction inspection and maintenance agreement process.
San Ramon is not part of the Alameda County Clean Water Program that covers Dublin and Pleasanton. The Contra Costa Clean Water Program has its own C.3 Guidebook and guidance documents. We know both programs and apply the right one to each project. See our stormwater management page for a full explanation of how C.3 compliance works across county lines.
Flood Control Coordination
Projects in San Ramon that affect drainage channels, flood control facilities, or waterways in the San Ramon Valley need to coordinate with the appropriate county flood control authority. Grading plans that alter drainage patterns or direct flow toward a public channel require review and, in some cases, an encroachment permit or right-of-way agreement. We identify those triggers early in site design and handle the coordination so it doesn’t surface as a comment late in plan check or during inspections.
San Ramon SWPPP Requirements
California’s Construction General Permit requires a Stormwater Pollution Prevention Plan for any project disturbing one or more acres of soil. In San Ramon, that means the SWPPP has to be prepared by a Qualified SWPPP Developer (QSD) and must be available on site during all construction activities. The SWPPP documents erosion controls, sediment barriers, non-stormwater management procedures, and a Rain Event Action Plan that adjusts based on weather forecasts and site inspection findings. Reco Prianto, PE, holds an active QSD/QSP credential. We prepare SWPPPs in-house and coordinate them with the grading permit package at first submittal. For phased projects, we handle SWPPP amendments when grading limits or site conditions change during construction.
Fire Flow Studies in San Ramon
A fire flow study documents whether the water distribution system serving your San Ramon site can deliver the flow rate and residual pressure that the fire authority requires for suppression. California Fire Code fire flow demands vary by building type, occupancy, and construction classification. Commercial buildings, multifamily residential, warehouses, and schools each carry different requirements, and the fire authority having jurisdiction reviews the analysis as part of the building permit. We prepare fire flow analyses that test available supply at the point of service against project demand, document any shortfall, and present alternatives such as on-site fire storage or pressure-zone adjustments when the main system can’t meet demand. Any San Ramon project with a required fire sprinkler system needs a fire flow study in the permit package. If current hydrant test data isn’t available from the water purveyor, we coordinate a field test as part of the study process.
Nearby Projects in the Tri-Valley and Bay Area
Calichi Design Group completed the Dublin Transit Center in neighboring Dublin, a new five-story, 507-space parking structure. That project required site civil engineering, utility design, and coordination with Dublin’s Engineering Division and transit infrastructure. Dublin sits directly adjacent to San Ramon, and the development patterns, utility infrastructure, and regulatory context in the two cities share significant overlap. We’ve also completed substantial work in Oakland, CA: the Fremont High School Net-Zero Campus involved demolition of 95 percent of an existing school campus and new construction of nine buildings totaling 190,000 square feet, with full utility infrastructure and stormwater management systems. The KIPP Bridge Academy charter school civil package covered grading, storm drainage, stormwater control, and utility plans for a two-story classroom building. That’s the kind of Bay Area institutional and commercial civil engineering experience we bring to San Ramon projects.
Frequently Asked Questions
What’s the difference between C.3 stormwater requirements in San Ramon versus Dublin or Pleasanton?
San Ramon is in Contra Costa County, so stormwater compliance runs through the Contra Costa Clean Water Program (CCCWP) and its C.3 Guidebook. Dublin and Pleasanton are in Alameda County and follow the Alameda County Clean Water Program and its C.3 Technical Guidance Manual. Both programs implement the same underlying Municipal Regional Permit from the San Francisco Bay Regional Water Quality Control Board, but the local C.3 guidance documents, sizing tools, and post-construction tracking requirements have real differences. We know both programs and apply the correct one to each project from the start.
Does Calichi handle SWPPP preparation in Contra Costa County?
Yes. Our QSD and QSP credentials are valid statewide. We prepare SWPPPs for projects in Contra Costa County, including San Ramon, under the same Construction General Permit that applies across California. We coordinate the SWPPP with the grading plan and include it in the first submittal package to the San Ramon Permit Center so reviewers have the complete civil package at the first submission.
What does a fire flow study include for a San Ramon commercial project?
A fire flow study for a San Ramon commercial project includes a site-specific demand calculation based on the California Fire Code and building type, a review of available hydrant flow test data or a new field test if current data isn’t available, and a comparison of demand versus available supply at the nearest serving hydrant. The written report documents the findings clearly and, if there’s a shortfall, presents the options and their cost implications. The fire authority reviews the report as part of the building permit. For most commercial projects, the process takes one to three weeks depending on data availability.
Can Calichi handle the full civil scope for a San Ramon office park or corporate campus?
Yes. We’ve worked on commercial and institutional sites of varied scales across the Bay Area, including parking structures, school campuses, and multi-building developments. We handle grading, drainage, utility coordination, SWPPP, fire flow, and dry utility design in a single contract. That keeps the civil scope coordinated and eliminates the scheduling gaps that happen when different consultants are working on overlapping plan sets at the same time.
