STORMWATER

The Park City stormwater system consists of gutters, grates, storm inlets, pipes, culverts, and detention and retention ponds. Much of our snowmelt and rain water is collected within our drainage system and delivered to natural streams or percolate into the aquifer. The storm drain system is in place match pre and post-development drainage conditions, preventing flooding and property damage throughout the city. This system includes 39 miles of piping, 31 miles of earthen channels, and over 1,600 inlet boxes.

As part of the Clean Water Act, Park City is mandated to mitigate the pollutants from storm drain runoff and snowmelt that can contribute to our watershed. In July of 2016, the City began implementing practices to meet state regulations of the Municipal Separate Storm Sewer System (MS4) permit. There are six Minimum Control Measures required by the Utah State Division of Water Quality to implement the MS4 Permit. Once fully implemented, the City and local contractors will face audits and possible fines if permit regulations are not met.

What is Stormwater and why should I care?

Pollution from stormwater runoff is a concern, especially in urban and sub-urban areas. Rainwater washing across streets and sidewalks can pick up sedimentation from construction sites, spilled oil, detergents, solvents, de-icing salt, pesticides, fertilizer, and bacteria from pet waste.

Park City's storm drains do not channel water to a regional wastewater treatment facility. Our stormwater drains into the Silver and McLeod Creeks, before making its way to the Weber River and eventually the Great Salt Lake.

In areas without proper maintenance, most surface pollutants are collected during the first rainfall of "first-flush" in any storm or snowmelt event. This is the period when the majority of pollutants are picked up by flow across lawns, parking lots, and roadways. The runoff is then carried, untreated, into water ways or percolates into our aquifer. These pollutants can increase algae content, reduce aquatic life, and require additional costly treatment to make the water safe for downstream water systems.

It becomes the duty of every resident, developer, contractor, builder, business owner, vacationer, and municipal employee to minimize stormwater pollution impact within Park City.
