How San Leandro Handles Environmental Rules: A Practical Guide

San Leandro maintains 151 local ordinances across all categories, and 5 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where San Leandro falls on the strict-to-permissive spectrum compared to other cities.

Grading & Drainage

A San Leandro grading permit (SLMC Title 7, Chapter 7-12 — Grading, Excavations and Fills) is required for movement of 50 cubic yards or more of soil (about 6 dump truck loads) or excavation 5+ feet deep. Drainage must convey storm waters to an approved natural watercourse or public storm drain.

Key details: Code chapter: SLMC Title 7, Chapter 7-12. Permit threshold: 50+ cubic yards or 5+ feet deep. Tech fee: 6% non-refundable surcharge. Permit portal: Accela Citizens Access (ACA). Permit center: 835 E. 14th Street, Mon-Thu 8am-4pm.

Grading without a permit is a violation enforceable as a code infraction with stop-work orders, after-the-fact permit fees (typically double standard fee), and required restoration. Failure to provide adequate drainage that causes runoff onto neighboring property may also create civil liability under California Civil Code §3479 (nuisance) and Water Code §7075 (obstruction of natural watercourses).

Stormwater Management

San Leandro Municipal Code Chapter 3-15 (Storm Water Management and Discharge Control Ordinance) prohibits non-stormwater discharges to the City's storm sewer system and requires C.3 BMPs for new development. The City participates in the Alameda Countywide Clean Water Program under the Bay Area Municipal Regional Stormwater Permit (MRP).

Key details: Code chapter: SLMC Chapter 3-15. Regional permit: Bay Area MRP (Order R2-2022-0018). Business license trigger: SB 205 NPDES enrollment proof. Spill hotline (work hours): (510) 577-3434. Clean Water program: Alameda Countywide Clean Water Program.

Violations are enforceable as municipal code infractions/misdemeanors. The City may issue notices of violation, stop-work orders, and administrative citations; clean-up and abatement costs may be assessed as liens. Knowing illegal discharges can also trigger State Water Board enforcement under the federal Clean Water Act and California Water Code with civil penalties up to $10,000 per day per violation (Water Code §13385). Report spills 7am-4pm at (510) 577-3434; after-hours (510) 577-3459.

This is not one of those rules that cities tend to ignore. San Leandro actively enforces its stormwater management requirements.

Flood Zones

San Leandro Municipal Code Title 7, Chapter 7-9 (Floodplain Management) implements the National Flood Insurance Program. The current FEMA Flood Insurance Rate Map (FIRM) for San Leandro was issued December 21, 2018 following a coastal study, with Special Flood Hazard Areas (SFHAs) along San Leandro Creek, San Lorenzo Creek, and the Bay shoreline.

Key details: Code chapter: SLMC Chapter 7-9. Current FIRM effective date: December 21, 2018. Original FIS date: September 1979 (FIRMs March 18, 1980). Substantial Improvement threshold: 50% of market value. Floodplain Administrator: Building Official, 835 E. 14th Street.

Construction without a floodplain development permit, or failure to elevate to BFE, is a violation enforceable as a municipal code infraction/misdemeanor with stop-work orders and required corrections. Non-compliance jeopardizes the City's NFIP Community Rating System status and can expose the property owner to denial of federally backed flood insurance and mortgages. Variances may only be granted under the narrow criteria of Chapter 7-9 (functionally dependent uses, historic structures).

This is one of the stricter rules in San Leandro's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Erosion Control

Under San Leandro Municipal Code Title 7, Chapter 7-12 (Grading, Excavations and Fills), §7-12-230 requires Erosion Control, Sedimentation Control, and Drainage Plans prepared by a Civil Engineer and approved by the City Engineer for any project requiring a grading permit.

Key details: Code section: SLMC §7-12-230. Plan preparer: Licensed Civil Engineer. Bond trigger: Grading exceeding 500 cubic yards. Grading permit threshold: 50+ cubic yards or excavation 5+ feet deep. State permit: Construction General Permit (1+ acre disturbed).

Grading without an approved erosion control plan, or failure to maintain BMPs, is a violation of SLMC Ch. 7-12 enforceable by stop-work order and code citation. The City may draw on the performance bond to complete required work. State Water Board penalties under the Construction General Permit can reach $10,000 per day per violation (Water Code §13385) for sediment-laden discharges to waters of the United States.

Coastal Development

San Leandro is NOT under California Coastal Commission jurisdiction (which covers the Pacific outer coast). Instead, the City's San Francisco Bay shoreline falls under the San Francisco Bay Conservation and Development Commission (BCDC), which regulates fill, dredging, and substantial use changes within 100 feet inland of the Bay shoreline under the McAteer-Petris Act (Gov. Code §66600 et seq.).

Key details: Regulating agency: BCDC (not Coastal Commission). Authority: McAteer-Petris Act, Gov. Code §66600 et seq.. Jurisdiction band: Bay + 100 feet inland of shoreline. Permit decision deadline: 90 days after complete application. Max administrative penalty: $30,000 + $6,000/day (Gov. Code §66641.5).

Unpermitted fill or development within BCDC's 100-foot band is enforceable by BCDC under Gov. Code §66641.5 with administrative civil penalties up to $30,000 per violation plus $6,000 per day of continuing violation. BCDC may also order removal of fill at the owner's expense. Local violations under San Leandro zoning are separately enforceable.

This is not one of those rules that cities tend to ignore. San Leandro actively enforces its coastal development requirements.

If you are a homeowner, renter, or business owner in San Leandro, take the time to understand these requirements before they become a problem.
