Overview

Chanhassen has abundant surface water resources, including lakes, streams, ponds, and wetlands. The city's Surface Water Management Plan (SWMP) outlines goals for managing these resources.

Water quality, lakeshore preservation, lake level variability, erosion/sediment control, and flood management are some of the critical issues that impact the quality of life enjoyed by all residents.

We all have a role in managing these resources to benefit wildlife ecosystems that rely on them. Whether directly using Chanhassen's many lakes, streams, ponds, and wetlands or runoff from yards, driveways, and streets, pollutants find their way into the water and degrade these valuable resources.

Stormwater Pollution Prevention Plan Open House

Date: Wednesday, December 17
Time: 3:30-5:30 p.m.
Location: Chanhassen City Hall

The City of Chanhassen invites residents to attend our annual Stormwater Pollution Prevention Plan (SWPPP) Open House. This open house is part of the city’s MS4 (Municipal Separate Storm Sewer System) program, which helps us protect local lakes, wetlands and waterways by reducing stormwater pollution.

Each year, we review our SWPPP to ensure it continues to meet state and federal requirements—and, just as importantly, to make sure it reflects the priorities of our community. Your input plays a vital role in shaping how we manage stormwater throughout the city.

What to Expect

1. Information on the city’s current SWPPP, including recent accomplishments and upcoming initiatives.

2. Opportunities to ask questions and learn how stormwater is managed in neighborhoods, parks, and local waterways.

3. A chance to provide comments, suggestions, or concerns that will help guide future improvements to the city’s stormwater program.

Why Your Feedback Matters

Stormwater pollution prevention is a community effort. Whether it's reducing runoff, improving water quality, or protecting natural areas, resident insight helps the city develop a stronger, more effective plan.

Public Comments

Adopt-a-Drain

The city is a partner with the Adopt-a-Drain program. Volunteering just fifteen minutes twice a month can help create cleaner waterways and healthier communities. Storm drains flow directly to local lakes, rivers, and wetlands as a conduit for trash and organic pollutants. Adopt-a-Drain asks residents to adopt a storm drain in their neighborhood and keep it clear of leaves, waste, and other debris to reduce water pollution. Learn more.
