Silverthorne's stormwater management fee addresses the Town’s aging infrastructure, helps reduce the potential for property damage due to stormwater drainage, and maintains local water quality.

Residential properties are charged $18 per quarter.

Commercial properties have a tiered rate based on impermeable surface:

• $5/month for 0-10,000 Sq. Ft. ($15/qtr; $60/year)
• $10/mo.: 10,001-40,000 Sq. Ft. ($30/qtr; $120/year)
• $50/mo.: 40,001-100,000 Sq. Ft. ($150/qtr; $600/year)
• $100/mo.: 100,001+ Sq. Ft. ($300/qtr; $1,200/year)

About Stormwater Management

Stormwater management programs focus on the quantity of water coming off of the landscape and the quality of that water.

Stormwater comes in pulses. When there is snowmelt or a storm event, water and its pollutants—roadway, agriculture, and suburban runoff— flows into rivers, lakes, and reservoirs. Pollutants can include trash, oil, grease, metals from brake pads, copper, and other elements, all of which can be toxic for our water and for aquatic life.

A stormwater management program helps address this challenge by funding improvements to the infrastructure that collects and manages the flow of stormwater.

Protecting and Preserving the Blue River Basin

Silverthorne is practically synonymous with the Blue River, which runs through downtown as part of its 680-square-mile journey from its headwaters west of the Continental Divide near Quandary Peak to the Colorado River near Kremmling. From the Blue River Trail to trout fishing and rafting, the Blue River anchors Silverthorne’s community with its beauty and healthy ecosystem.

To understand the pressures on the river and develop actionable solutions, the non-profit Blue River Watershed Group has partnered with the Town of Silverthorne and other area organizations and municipalities.

Water's Role in Our Recreation and Livelihoods

While Summit County’s recreation economy is most often connected to winter snow sports, water recreation—fishing, specifically—also contributes significantly to locals’ livelihoods.

The importance of preserving and protecting our water and habitat cannot be understated. And yet, the health and safety of our fisheries are under significant threat.
