San Rafael's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In San Rafael, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Flood Elevation Requirements

New and substantially improved buildings in San Rafael's mapped flood zones must elevate the lowest floor at least one foot above the base flood elevation, plus predicted 30-year settlement, before occupancy.

Key details: Freeboard: 1 foot above base flood elevation. Plus: 30-year predicted settlement allowance. Zones covered: AE, AH, V, and VE. Certification: Registered engineer or surveyor required.

A structure lacking the required elevation certificate is presumed in violation under SRMC § 18.20.010's 'Violation' definition until documentation is provided; noncompliance is a misdemeanor enforceable under § 18.30.030.

Boat Dock Permits

Building or placing a pier, dock, wall, bulkhead or breakwater on San Rafael's tidelands requires a City tidelands permit from the Department of Public Works before construction: unpermitted dock work is a code violation under SRMC Title 17.

Key details: Permit type: Tidelands Permit. Issuing agency: Dept. of Public Works. Fill/excavation ≥1 acre: Planning Commission hearing. Permit term: 1 year, renewable. Covers: Piers, docks, bulkheads, breakwaters.

Constructing or placing a dock, pier, wall, bulkhead or breakwater on city tidelands without an approved tidelands permit violates SRMC §17.10.030 and can result in a stop-work order plus penalties under the city's general enforcement provisions.

This is not one of those rules that cities tend to ignore. San Rafael actively enforces its boat dock permits requirements.

Stormwater Management

San Rafael bans any non-stormwater discharge into its storm drain system under the Urban Runoff Pollution Prevention Ordinance, Chapter 9.30. Violations are a public nuisance and a misdemeanor or infraction, enforceable by administrative citation, civil action, or summary abatement with a lien on the property.

Key details: Core prohibition: No non-stormwater discharge to storm drains. Enforcing officials: City manager, public works director, fire chief, health officer. Irrigation leak repair window: 72 hours to fix and report. Violation classification: Misdemeanor or infraction, per-day. Civil remedy: Treble damages under §§1.42.020-.040.

Under § 9.30.200, any condition violating Chapter 9.30 is deemed a public nuisance that the city may summarily abate, restore, or enjoin, and § 9.30.210 makes abatement and restoration costs a lien against the property. Section 9.30.250 makes violating any mandatory requirement of the chapter a misdemeanor, though the enforcement authority may instead charge it as an infraction, with fines and imprisonment capped at the limits set in Government Code §§ 36900-36901; each day a violation continues is a separate offense. The city attorney may also bring a civil action under § 9.30.260 seeking injunctions, investigation and cleanup costs, compensatory damages for harm to water quality or wildlife, and treble damages under §§ 1.42.020-1.42.040, and an authorized enforcement official may issue cease-and-desist orders under § 9.30.270 ranging from verbal warnings to formal administrative enforcement.

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

Erosion Control

San Rafael caps graded slopes at 2:1 and retaining walls at 8 feet for new subdivisions, and requires an erosion control plan and city engineer sign-off on drainage.

Key details: Max graded slope: 2:1 (steeper needs engineer approval). Max retaining wall: 8 feet without Planning Commission OK. SWPPP required: subdivisions of 5+ acres. Drainage rule: lots must drain to a street.

Grading, erosion control, and drainage plans are reviewed and conditioned by the city engineer as part of subdivision improvement plan approval; a grading permit will not issue without compliance, and noncompliant slopes or walls require discretionary Planning Commission or city engineer approval.

Flood Zones

San Rafael requires a floodplain development permit before any construction begins within FEMA-mapped special flood hazard areas, covering the Canal district and other low-lying neighborhoods under Marin County's 2017 flood insurance maps.

Key details: Permit required: Before construction in flood hazard area. Administered by: City public works director. Violation: Misdemeanor citywide. Maps adopted: FEMA FIRM effective August 15, 2017.

Constructing, filling, or developing in a mapped flood hazard area without a floodplain development permit is a misdemeanor under SRMC § 18.30.030, and the city may take further lawful action to prevent or remedy the violation.
