Storm Drain Master Plan

Town Council adopted the Storm Drain Master Plan (SDMP), originally created as a proactive approach to determine the needs, costs, and priorities associated with the Town’s 27 miles of storm drain collector system and 35 creek culverts. This information is critical for the Town to properly program: future repair; replacement; and consideration of increased capacity of the Town’s storm drains. The SDMP has identified $26 million of unfunded improvements.

Addendum

On November 13, 2019, Town Council accepted the 2019 Addendum to the Storm Drain Master Plan which serves as a standalone document :

  • Identify funding needs over the next ten years
  • Incorporate operations and maintenance program needs
  • Quantify needs to address high and moderate capital needs over the next ten years
  • Reprioritize storm drain projects
  • Update cost estimates

The 2019 Addendum is meant to serve as a planning tool for the Town to identify $540,000 in funding to implement a $420,000 a year enhanced operations and maintenance program and a $120,000 a year capital improvement program to complete nine capital improvement projects.
