Glendale, CA Environmental Rules: Erosion Control (2026)

050 requires anyone commencing or continuing construction activity that disturbs one acre or more of soil through clearing, grading, excavation or demolition to first demonstrate to the director of public works that they have filed a Notice of Intent to comply with the California General Permit for stormwater discharges associated with construction activity, or have obtained a waste discharge identification (WDID) number from the State Water Resources Control Board and prepared a state Stormwater Pollution Prevention Plan (SWPPP). That documentation must be kept at the construction site at all times, and as a condition of the grading or building permit itself, the applicant's construction plan must incorporate a stormwater pollution prevention plan that the director of public works reviews and approves.

060 extends a lighter version of the rule to smaller sites, disturbing less than one acre: those projects need an approved plan providing minimum stormwater quality protection, implemented throughout construction. 090 spells out the paperwork the city requires before issuing a building or grading permit on a one-acre-or-larger site or a site within a larger common plan of development exceeding one acre: a copy of the NPDES permit or Notice of Intent, the WDID number, and a copy of the SWPPP itself; permit documents must stay available on site during regular business hours, and if ownership changes mid-project, the new owner must submit its own NOI and SWPPP.

140 requires one copy of the approved SWPPP, erosion and sedimentation control plan, and owner's certification to be kept on site at all times while work is in progress, available for the director of public works to verify best management practice compliance. 150(B) requires the city to inspect construction general permit sites at least once a month, and any observed violations are reported to the Regional Water Quality Control Board.
