Stormwater Master Plan

Stormwater Master Plan

Extreme rain events appear to be occurring more regularly and with higher intensities.  The City's stormwater conveyance system collects runoff from roofs, driveways, sidewalks, and streets and parking lots, transporting it safely to creeks and rivers.  The management of this system is critical to reducing flood risks, property damage and loss of life, and for maintaining and improving water quality.

On November 1, 2016, the City Council adopted a new Stormwater Master Plan. The last Stormwater Master Plan was completed in 1998 and has become outdated in its ability to guide future decisions.  The City began development of the updated master plan in June of 2015.  This initial revamp reflects the collaborative effort of City and consultant staff to bring a fresh perspective and innovative thought to accomplish the following objectives.
  1. Reflect the City's vision for the future as presented in EnvisionCR
  2. Develop a hydraulic model that can serve as a platform to better define needs and consider cost-effective solutions
  3. Reflect City staff efforts to maintain and preserve the existing stormwater system through asset management
  4. Prioritize and recommend project for the capital improvement plan
  5. Identify financial needs and potential funding to close the gap between revenues and needs
  6. Consider potential policy solutions to address fundamental issues that contribute to current flooding problems
  7. Establish the foundation for annual updates to expand and improve upon the initial plan
The hydraulic modeling is performed at two scales.
  • A citywide "macro-level" model which provides an overall picture of where areas of the city experience stormwater conveyance challenges, and how widespread the issue is (measured in city blocks and/or square miles)
  • Detailed "basin-level" models, where each drainage basin is analyzed in detail using topographic and detailed stormwater conveyance system data to pinpoint street and property flooding severities
The current edition (FY 2016) and the next four years of work (until FY 2020) are subject to change as the plan continues to develop.  A new five-year plan will be developed after 2020.
