Full Breakdown
2210(b)(18) must include drainage and erosion control plans reviewed and approved by the City Engineer pursuant to Chapter 7 of Title 5, the city's Stormwater and Urban Runoff Pollution Control Regulations. 14 of Title 9 extends that standard citywide: all development must conform to the stormwater standards of the State of California as implemented through Chapter 7 of Title 5, and site design must minimize impervious surfaces and keep setback areas permeable where feasible. 112(a) backs this with a permitting checkpoint, requiring proof of compliance with the applicable NPDES permit and the city's development construction program, in a form acceptable to the Engineer, before any grading, building, or occupancy permit is issued.
113 must also prepare a Standard Urban Stormwater Mitigation Plan with low-impact-development measures such as infiltration, bioretention, and rainfall harvest, reviewed by the Engineer before any discretionary permit or certificate of occupancy issues. New single-family hillside homes carry added duties: conserving natural areas, protecting slopes and channels, and diverting roof and surface runoff to vegetated areas unless that would destabilize a slope. 09, with separate fees for retaining walls or major drainage structures.
Violations & Fines
Section 5-7.114 lets the City Engineer declare an erosion or drainage violation, or a failure to follow an approved stormwater mitigation plan, a public nuisance subject to abatement at the owner's expense, cease-and-desist orders, and civil actions seeking injunctions, cost recovery, and compensatory damages. Violations are also punishable as misdemeanors under Section 1-2.01, up to a $1,000 fine or six months in jail under Section 1-2.02, each day counted separately, and can trigger revocation of the related permit.
