Stormwater Management Program

Welcome to the Paradise Stormwater Management Program. At this site, you will be able to learn what you need to know about stormwater management and how you can make a difference in our very own community.

Background Information

In Paradise, as in all developed areas, rainwater which falls during storm events runs off buildings, homes, parking lots and streets. Now defined as stormwater, this water travels along pipes, drainage swales, or culverts and ultimately into regional water bodies such as Lake Oroville and Butte Creek. During this process, the stormwater picks up trash (wrappers, cigarette butts, Styrofoam cups, etc.) and toxins (used motor oil, antifreeze, fertilizers, pesticides, pet waste, etc.). These pollutants are picked up by any flowing water such as rainwater, household sprinkler systems, fire hydrants, personal hoses, etc., and transported to local waterways. 

Mandated by Congress under the Clean Water Act in 1990, the NPDES Stormwater Management Program is a comprehensive national program for addressing non-agricultural sources of stormwater pollution that adversely affect the quality of our nation's waters. The Program uses the National Pollutant Discharge Elimination System (NPDES) to require cities to implement controls designed to prevent harmful pollutants from being washed by runoff into local water bodies. The Town of Paradise, under the NPDES Small MS4 Phase II permit, is actively pursuing these controls today to ensure a cleaner, safer tomorrow.

Paradise Post-Construction Standards Plan

The purpose of this document is to provide project proponents and municipal plan checkers with information on how to meet the State Water Board’s requirements for mitigating the negative impact of increases in storm water runoff caused by new development and redevelopment.  This document accomplishes this goal through the incorporation of Low Impact Development standards and hydromodification management techniques.  Low Impact Development (LID) mitigates excessive runoff by the use of control measures that utilize evapo-transpiration, infiltration, capture / reuse, and biotreatment to mimic the runoff of a natural environment.  Hydromodification techniques are used to design development sites so that post-construction runoff flow rates do not exceed those of the pre-construction conditions.

Using this document, project proponents will be equipped to provide a submittal package to the municipality as a part of its permitting or plan check process to adequately demonstrate how the project will meet the LID and hydromodification requirements.

Plan checkers will be able to use this document to objectively and sufficiently condition discretionary projects with the required post-construction storm water design requirements. Please find below a list of downloads relating the to the Post-Construction Standards Plan, its applicability and step-by-step guidance for completion.
