Stormwater Regulations

Pacific Grove Municipal Code

Pacific Grove Municipal Code Chapter 9.30, Storm Water Management and Discharge Control, regulates stormwater discharge and related issues within the City.

State Water Resources Control Board


The work the City does to prevent stormwater pollution is regulated under the jurisdiction of the Central Coast Regional Water Quality Control Board, Region 3 (Regional Board), the enforcement arm of the State Water Resources Control Board (Water Board). The State Water Resources Control Board adopted a General Permit for the Discharge of Storm Water from Small MS4s (WQ Order No. 2013-0001-DWQ) to provide permit coverage for smaller municipalities, including non-traditional Small MS4s, which are governmental facilities such as military bases, public campuses, and prison and hospital complexes.

MS4 permits require the discharger to develop and implement a Stormwater Management Plan/ Program with the goal of reducing the discharge of pollutants to the maximum extent practicable (MEP). MEP is the performance standard specified in Section 402(p) of the Clean Water Act. The management programs specify what best management practices (BMPs) will be used to address certain program areas. The program areas include public education and outreach; illicit discharge detection and elimination; construction and post-construction; and good housekeeping for municipal operations.

Monterey Regional Storm Water Management Program

Meetings are OPEN TO THE PUBLIC!
Interested stakeholders are encouraged to attend and provide input!

10 a.m., fourth Wednesday
(unless otherwise posted),
at MRWPCA, 5 Harris Court, Building D, Monterey (Ryan Ranch), CA 93940

The Cities of Monterey, Carmel-by-the-Sea, Del Rey Oaks, Sand City, Seaside, Pacific Grove and the County of Monterey are seven local agencies that have joined to develop and implement a regional storm water program for the Monterey Peninsula and surrounding areas. This group meets monthly to discuss urban runoff issues and implement components of the Monterey Regional Storm Water Management Program (MRSWMP).

Monterey One Water (formerly MRWPCA) acts as the group’s administrative agent, holding meetings and working with the group to develop this regional program.

Annual Report

The City is required to submit an annual report as required by General Permit NO. CAS000004: Waste Discharge Requirements for Storm Water Discharges from Small Municipal Separate Storm Sewer Systems. The Annual Report describes permit compliance activities performed by the City during the time period of July 1, 2013 to June 30, 2014 to implement pollution prevention locally and protect local water quality.

Development and Redevelopment Requirements

On July 12, 2013 the Central Coast Regional Water Quality Control Board adopted Post Construction Requirements (PCR) for development and re-development projects. These requirements were implemented by all agencies in the Region, effective March 6, 2014.

The primary goal of PCR is to protect watershed health and processes through development runoff controls using:

  1. Site Design & Runoff Reduction
  2. Water Quality Treatment
  3. Runoff Retention
  4. Peak Management

The City is required to implement the adopted Post Construction requirements through the development review process. To determine if your project is subject to PCR and for more information see the Planning Division.
