The rules cover illicit discharges, construction-related erosion, and commercial or landscape pesticide use that can enter storm drains. For the controlling ordinance text, see the Pleasanton Municipal Code and the city stormwater program pages.Municipal Code[1] City Stormwater Program[2]

Applications & Forms

The City page and municipal code describe permitting expectations for erosion and runoff control, but specific city form numbers, fees, and submission portals for stormwater-specific permits are not published on those pages. For state-level construction stormwater permit requirements (SWPPP/Construction General Permit) consult the State Water Resources Control Board guidance.State Water Boards - Stormwater[3]

Large construction projects generally need a Stormwater Pollution Prevention Plan (SWPPP) under state permit rules.

Common violations and typical outcomes

  • Illicit discharge to storm drains (dumping paint, wash water): inspection, order to abate, possible civil action.
  • Poor construction erosion controls causing sediment runoff: stop-work or corrective order and requirement for SWPPP implementation.
  • Improper pesticide application resulting in runoff: investigation, required corrective measures, and potential coordination with county or state pesticide regulators.

How to comply — practical action steps

  • Plan: include erosion and sediment control measures and integrated pest management in project plans.
  • Document: keep SWPPP records, application logs, and pesticide labels/material safety data sheets.
  • Report: immediately notify the city of spills or visible runoff; use the stormwater program contact for guidance.City Stormwater Program[2]
