what we do

Stormwater

Developing best management practices

Stormwater management practices and regulations have advanced rapidly in recent years. To reduce the impact of built areas, Parametrix uses low impact development (LID) principles and practices. Our solutions optimize the use of on-site natural features to improve water quality, protect habitat and wildlife, reduce life-cycle costs, and enhance communities. We apply the latest technologies to provide clients better ways to manage stormwater.

Surface Water Comprehensive Plan Update
​​Des Moines, Washington
Client: City of Des Moines

The City of Des Moines’ Surface Water Comprehensive Plan will outline the City’s stormwater management program to be implemented over the next NPDES permit term (2013-2018). Solutions are being developed to ensure that the stormwater infrastructure, policies, and funding mechanisms will meet the City’s future needs. These solutions will be incorporated into the CIP by screening potential projects, providing planning-level opinions of costs, and assisting in prioritizing the projects. Public involvement is an important part of the process under the City’s NPDES Phase II municipal stormwater permit and extensive outreach has occurred including public meetings.

"Over the past year I have had the pleasure of working with the Parametrix team on the City's Storm and Surface Water Utility Comprehensive Plan Update. This has truly been a collaborative effort... working alongside city staff from a variety of departments and programs in addressing policy, regulatory and natural resources challenges."
