Stormwater Quality Program - City of Longmont Skip to main content
Overview

Urbanization has the potential to significantly impact the the ecological health of our waterways. The City of Longmont’s Stormwater Quality Program is tasked with helping to protect the rivers, lakes and streams that flow through our community.

The Stormwater Quality Program hosts virtual office hours every Monday from 3:00 – 4:00 pm and Thursday from 10:00 – 11:00 am.

The Keep it Clean Partnership made up of six communities: the cities of Boulder, Longmont, Louisville, and Lafayette, the town of Superior, and Boulder County. While these communities originally came together to collaborate on stormwater management, in recent years the organization’s focus has shifted to also include broader watershed level efforts.

Municipal Separate Storm Sewer System (MS4)

The City of Longmont owns and operates a complex storm drainage system known as a Municipal Separate Storm Sewer System. It is designed to efficiently transport rain water and snow melt away from our homes and streets, into the inlets and grates located around the city – ultimately flowing into the surface waters – rivers, creeks, and streams – that run through town.

 

This runoff water tends to collect common pollutants found in our streets, our rights-of-way, and often even our personal property. Pet waste, yard waste (like leaves), motor oil, car wash runoff, paint, sediment, garbage, and other pollutants all have the potential to flow untreated through our storm sewer system, into the City’s surface waters. This can have a significant impact on surface water quality, threatening the health of our environment, wildlife and residents, as well as our ability to safely recreate in these waterways.

 

The City of Longmont’s Stormwater Quality Program is here to help.

 

The River Starts Here!

Protecting our waterways from pollution requires a concerted effort on the part of the entire Longmont community. Businesses large and small, home owners associations, contractors, developers, and even individual residents all have a role to play in preserving and protecting this essential community resource.

 

Whether you are a concerned resident, a conscientious businessperson, or a responsible developer, you can help protect our surface waters!
