Civil Engineering in Concord, CA
Concord is the largest city in Contra Costa County and carries a diverse project mix: suburban commercial, industrial, multifamily residential, institutional, and a long-running pipeline of work tied to the Concord Reuse Project redevelopment of the former Naval Weapons Station. Calichi Design Group handles site civil work across Contra Costa County, and Concord projects are a consistent part of our East Bay practice.
We cover the full civil scope for Concord projects: site planning, grading and drainage, water and sewer design, stormwater compliance, fire flow analysis, ADA, and dry utility coordination. Our Oakland office is about 25 miles from downtown Concord. We maintain working relationships with the agencies Concord projects regularly involve, including the city’s Engineering Division, Contra Costa Water District, and the Contra Costa County Fire Protection District.
Permitting Agencies and AHJs for Concord Projects
The City of Concord’s Engineering Division, within the Community Development Department, is the primary permit authority for civil improvements in Concord. The Engineering Division handles encroachment permits, grading permits, and sewer permits. Their offices are at 1950 Parkside Drive, Concord, CA 94519, and the city’s Permit Center is the intake point for most permit applications. Building permits are handled separately by the Building Division. Projects requiring subdivision, parcel map approval, or design review bring Planning into the coordination loop as well.
Water supply in Concord is provided by the Contra Costa Water District (CCWD), which serves more than half a million people across Contra Costa County from offices on Concord Avenue. Any project requiring a water service connection, meter sizing, fire service connection, or will-serve letter needs to coordinate with CCWD. We handle that coordination as part of the civil scope and prepare connection applications, sizing calculations, and any required hydraulic submittals for CCWD review.
Fire protection in Concord is provided by the Contra Costa County Fire Protection District, widely known as Con Fire, with headquarters at 4005 Port Chicago Highway in Concord. Con Fire serves as the Authority Having Jurisdiction (AHJ) for fire code compliance, fire access road design, and fire flow requirements on most Concord projects. Projects with significant fire flow demands or complex access configurations need Con Fire coordination during design, not just at final inspection.
Stormwater compliance in Concord falls under the Contra Costa Clean Water Program (CCCWP), which administers NPDES stormwater permit requirements for Contra Costa County municipalities under the SF Bay Region Stormwater Permit. Construction sites disturbing one acre or more require a SWPPP under the statewide Construction General Permit, filed through SMARTS. Post-construction projects meeting the applicable impervious surface thresholds must incorporate stormwater treatment measures into the site design.
Civil Engineering Services for Concord Projects
Our scope for Concord projects covers the full range of site civil work:
- Site Planning and Feasibility: We review entitlement conditions, map utility constraints, and identify permitting path issues before you invest in full construction documents.
- Grading and Drainage: Concord’s terrain ranges from flat valley floor to steeper hillside terrain approaching Mt. Diablo. We design grading and drainage plans that meet City standards and manage runoff correctly for the site conditions.
- Water and Sewer Design: We coordinate with CCWD on connection sizing, meter placement, and backflow requirements, and we design on-site water and sewer systems that connect properly to the public infrastructure.
- Stormwater Management: We design stormwater treatment SCMs under the SF Bay Region Stormwater Permit requirements, prepare hydraulic sizing calculations, and draft Operations and Maintenance agreements for post-construction compliance sign-off.
- Fire Access and Fire Flow Analysis: We design fire apparatus access roads to California Fire Code and Con Fire standards, and we prepare fire flow studies with stamped hydraulic calculations for Con Fire review.
- Dry Utility Coordination: We manage joint trench design and coordination with PG&E and telecom providers for underground utility routing in Concord’s franchise corridors.
- ADA and Path of Travel: We calculate cross-slopes, running slopes, and landing geometry to confirm compliance and get through plan check without excessive corrections.
- Permitting and Plan Check: We prepare and manage civil plan packages through the City of Concord Engineering Division and coordinate with the Building Division on cross-disciplinary review items.
Concord SWPPP Requirements
Any Concord project disturbing one acre or more during construction requires a Stormwater Pollution Prevention Plan under California’s Construction General Permit. Reco Prianto, PE, QSD/QSP prepares SWPPPs in-house, including risk-level determinations, BMP specifications, monitoring plans, and SMARTS portal filings. We also handle annual report submittals and amendments required during the construction phase. The QSD function stays in-house, not subcontracted out.
For post-construction stormwater management in Concord, the Contra Costa Clean Water Program requires stormwater treatment for projects that create or replace specified amounts of impervious area above the applicable thresholds. We assess whether your project triggers those requirements, design compliant SCMs, prepare sizing calculations, and write the Operations and Maintenance agreements the city requires before occupancy. Redevelopment projects have their own threshold analysis, and we work through that as part of the early feasibility review.
Fire Flow Analysis for Concord Projects
A fire flow study is required for new construction, major additions, and changes in occupancy that increase fire flow demand. The study confirms that the water distribution system can deliver the required flow rate at the minimum required residual pressure at the point of service. Con Fire is the AHJ that reviews and approves this analysis for most Concord projects.
For Concord projects, we start with available flow test data or CCWD water system information for the project location. We calculate the required fire flow based on construction type, occupancy classification, and building area per the California Fire Code. If available supply doesn’t meet demand, we evaluate solutions: a larger service connection from a higher-capacity main, on-site fire water storage, or a booster pump system. We prepare stamped hydraulic calculations and submit the package to Con Fire as part of the building permit coordination.
The Contra Costa Water District’s distribution infrastructure sets the baseline for fire hydrant supply in Concord. Understanding available pressure and flow at the project’s service point, and how that compares to Con Fire’s required flow rates and residual pressures, is the core of the fire flow analysis. See our East Bay civil engineering page for more on how we approach fire flow analysis in the broader regional context.
Nearby Projects and Bay Area Track Record
We don’t have a completed project in Concord itself. What we have is extensive project experience across the East Bay and Bay Area that demonstrates our capability for the types of work common in Concord.
In Dublin, about 20 miles from Concord, we completed civil engineering for the Dublin Transit Center, a 516-space, five-story parking structure on a 2.5-acre parcel. That project involved coordination with BART, the City of Dublin, and Alameda County, and it required careful infrastructure design on a compact urban infill site with multiple stakeholder agencies involved in review.
In Kentfield, accessible from Concord via the Richmond-San Rafael Bridge, we handled civil engineering for Fusellman Hall at Marin Community College, including site survey, grading, drainage design, utility coordination, and stormwater C.3 compliance planning. Community college campuses carry their own regulatory overlay alongside local permitting, and we navigated that without complications.
In Oakland, we delivered the Fremont High School Net-Zero Campus, a 190,000-square-foot, nine-building school with full utility infrastructure, stormwater systems, and DSA review, and KIPP Bridge Academy, a two-story charter school with grading, drainage, stormwater control, and utility design in a dense urban setting. Both projects reflect the regulatory complexity typical of Bay Area public agency work.
Our site civil engineering services are available across Contra Costa County and the broader Bay Area.
Why Hire Calichi for Your Concord Project
We focus on site civil and water/stormwater engineering. That focus means your project manager isn’t dividing attention across disciplines. For Concord clients, the practical result is:
- Fixed-fee proposals. The civil cost is set before we start, not discovered during billing.
- QSD/QSP in-house. Reco Prianto, PE, QSD/QSP prepares SWPPPs directly and manages SMARTS filings without routing work through a subcontractor.
- Dry utility in-house. We offer dry utility consulting as a separate service, so your PG&E and telecom coordination can stay under one contract with us.
- Multi-state licensure. If your program extends beyond California, we’re already licensed in seven states (CA, OR, WA, HI, AZ, CO, NM).
- Con Fire and CCWD familiarity. We’ve worked with Contra Costa County agencies and understand how to prepare submittals that move through their review process efficiently.
Frequently Asked Questions: Civil Engineering in Concord, CA
Which city department handles civil engineering permits in Concord?
The Engineering Division within the City of Concord’s Community Development Department handles encroachment permits, grading permits, and sewer permits for projects in Concord. Building permits are managed separately by the Building Division. Both departments operate out of the city’s offices at 1950 Parkside Drive, Concord, CA 94519, with the Permit Center serving as the intake point for applications. The city also offers Permit Pal as an online portal for certain permit types.
Does Contra Costa Water District review fire flow studies for Concord projects?
Fire flow studies for Concord projects are reviewed and approved by Con Fire (Contra Costa County Fire Protection District) as the AHJ. CCWD reviews plans for water service connections and fire service lines as part of their connection approval process. In practice, we coordinate with both agencies to make sure the hydraulic analysis and the physical connection design align with what each agency requires. A fire flow study that Con Fire approves but CCWD won’t connect is not a solved problem.
What is the Contra Costa Clean Water Program and how does it affect my Concord project?
The Contra Costa Clean Water Program (CCCWP) administers stormwater requirements for municipalities in Contra Costa County, including Concord, under the SF Bay Region Stormwater Permit. Projects creating or replacing impervious surface above the applicable thresholds must incorporate stormwater treatment into the site design. We assess whether your project triggers those thresholds, design the required SCMs, prepare hydraulic sizing calculations, and write the Operations and Maintenance documentation the city requires for post-construction compliance approval.
Do I need a civil engineering SWPPP for a project in Concord?
Yes, if you’re disturbing one acre or more of land during construction. The statewide Construction General Permit applies to Concord projects the same as anywhere else in California, and it requires a SWPPP prepared by a QSD and filed through SMARTS before grading starts. For projects under one acre, the city’s grading permit may still require an erosion control plan as part of the civil submittal. We handle both.
Can Calichi handle the civil engineering, SWPPP, and fire flow study for a Concord project as one scope?
Yes. We regularly deliver all three as a coordinated package. The civil grading and drainage plans, the SWPPP erosion control plan, the post-construction SCM design, and the fire flow hydraulic calculations all need to be internally consistent. When those documents come from the same team, you don’t end up with a drainage plan that contradicts the SWPPP or a fire service line that doesn’t fit the utility plan. We prepare and manage the complete package through both city and agency review.
