Any community that either has experienced growth or desires to grow understands that master planning is key to making a sound investment of resources, providing a framework for growth, and expanding in a way that is consistent with the long-term vision of the community.

Stormwater master planning takes this approach and applies it specifically to stormwater management, funding, and infrastructure. The following is a list of key focus areas that could be addressed by a stormwater master planning effort:

Existing Infrastructure Evaluation

  • System inventory
  • System evaluation/condition assessment
  • Prioritize maintenance
  • Hydrology and hydraulics analysis
  • System conveyance capacity

Public Engagement

  • Flooding feedback
  • Citizen input
  • Future vision and priorities

System Improvements

  • System size upgrades
  • Flood reduction analysis
  • Capital improvement project identification


  • Stormwater utility
  • Development stormwater fee
  • Grant and partnership opportunities

Regulatory Requirements

  • Existing requirements
  • System documentation
  • Future requirements
  • Define stormwater standards

Future System Expansion

  • Redevelopment needs
  • Conveyance sizing
  • Regional detention opportunities
  • Future project coordination

Stormwater master planning can be customized to fit the needs of the community. For example, communities with limited potential for geographic growth can focus more on the existing system evaluation, system improvements to address current issues and redevelopment opportunities, and funding for long-term system operation and maintenance. In contrast, communities with geographic growth potential can also look at future system expansion opportunities, defining stormwater standards, and exploring funding opportunities.

This type of planning puts the community in a position to respond to opportunities with clear direction and vision. The initial investment to do stormwater master planning can even help you save dollars and time in the future. For example:

  • If a funding source becomes available, it helps the community respond with real projects that have been studied, improving the chances for a successful submittal.
  • If a development opportunity is presented in a planned growth area, it outlines clear stormwater system infrastructure requirements for future growth.
  • If other infrastructure projects become a priority, it provides an opportunity to coordinate this project with identified stormwater system improvements.

The bottom line is that stormwater master planning is in an effective tool to help communities grow and be prepared for opportunities that come their way.
