Engineering & Planning
Engineering and Planning staff are responsible for restoration, protection, and preservation of surface waters and water quality within the City of Morro Bay as well as maintenance, repair, mapping, and evaluation of drainage systems within the public domain, including all street rights-of-way.
Staff reviews development applications to ensure they provide designs which are environmentally conscious, enhance water quality, and preserve and protect coastal waters and resources. All development and redevelopment projects which create or replace more than 2,500 square feet of impervious area must incorporate Stormwater Management controls as described in the Stormwater Management Guidance Manual for Low Impact Development and Post-Construction Requirements. 2 versions of the manual are available. The condensed EZ Manual is for individual single family homes. The Main Manual is used for all other projects. A Google Earth overlay is provided to precisely locate your projects Watershed Management Zone.
Stormwater Management Permit
The City of Morro Bay is in compliance with enrollment procedures under the National Pollutant Discharge Elimination System (NPDES) General Permit for the discharge of stormwater from small Municipal Separate Storm Sewer Systems (MS4). The California Water Board's current Phase II Small MS4 General Permit became effective on July 1, 2013 (Order No. 2013-0001 DW).
For each year of the General Permit, the City must comply with a detailed list of requirements aimed at improving stormwater quality in the region. The requirements fall into 10 categories:
- Program Management
- Education and Outreach
- Public Participation and Involvement
- Illicit Discharge Detection and Elimination (IDDE)
- Construction Site Storm Water Runoff Control Program
- Pollution Prevention / Good Housekeeping for City Operations
- Post-Construction Stormwater Management Program
- Water Quality Monitoring
- Program Effectiveness Assessment
- Total Maximum Daily Loads Compliance
- Annual Reporting
Each year the City completes and submits an Annual Report online to the Central Coast Regional Water Quality Control Board (CCRWQCB) via the California Water Board's SMARTS website. The Annual report verifies that the City has completed all the necessary tasks required by the General Permit for that year in order to achieve compliance.
Annual Reporting Prior to 2014
Prior to 2014, a written Annual Report was submitted to the CCRWQCB. These Annual Reports focused on the Best Management Practices (BMPs) outlined in the City's Stormwater Management Program (SWMP), and for each BMP, provided:
- A description of the BMP
- The measurable goal
- How the measurable goal was achieved, including a statement whether or not the measurable goal was achieved
- The effectiveness assessment
- Any proposed changes and a short summary of the activities for next permit cycle
The flood control program maintains all storm drain facilities and creeks on public property or easements within the City and coordinates emergency response during heavy storms. This program has 2 major activities:
- Storm Drain and Creek Maintenance - Examples of the operations performed include: cleaning, clearing, stabilization and restorations of streams and channels; tail ditch work installation and maintenance of Rip Rap; and other miscellaneous erosion control measures and maintenance functions related to the open channels. The Stormwater Management Division also coordinates cooperative creek maintenance among property owners and public agencies as well as providing ongoing monitoring of waterways passing through private property for litter and pollution.
- Storm Emergency Response - The Stormwater Management Division provides monitoring and emergency response assistance during heavy storm events, ensuring that pollution prevention measures are maintained and functioning as intended to protect water quality.
- Storm Preparedness - The City has prepared a Guide for Storm Preparation to assist our residents in preparing for the winter rains. You can also visit www.floodsmart.gov for more information. https://www.morro-bay.ca.us/DocumentCenter/View/11828/MB-Stormwater-Management-MAIN-Manual
