Introduction
Stormwater is the runoff that occurs over land, roads, parking lots, roof tops and other hard surfaces during and after rain events. If it rains enough, the water cannot be absorbed into the ground and instead flows over hard surfaces (impervious areas) where it picks up dirt and pollutants. Eventually, this polluted runoff makes its way into streams, rivers, and lakes carrying everything it picked up along the way.

Every driveway, sidewalk, rooftop, patio or other hardened surface in the City of Creedmoor contributes to the rain water that makes its way into ditches, streams and ultimately, Falls Lake. Stormwater drains and ditches along the roadside are designed to control the flow of stormwater and keep it from picking up too many harmful materials.

Factors That Contribute to State Regulation

Creedmoor is nestled between Ledge Creek on the west connected to the city’s Lake Rogers, and Robertson Creek whose tributaries Beaverdam Creek and Cedar Creek form the easternmost boundaries of the city. We are stewards of these scenic assets, and water that flows into these creeks carries runoff out of the city and down into Falls Lake.

Major Creek Drainage Basins

Falls Lake is an almost 12,500-acre reservoir managed by the US Army Corps of Engineers located in northern Wake and Durham counties that accepts runoff from streams and rivers in Orange, Person, Granville, Wake and Durham counties. While the collected water provides the drinking water source for over 500,000 people in Raleigh and a large portion of Wake County, pollutants from runoff have led to rising levels of Nitrogen and Phosphorus in the lake. 

North Carolina Department of Environmental Quality, Division of Water Resources (NCDEQ-DWR) designated the lake "impaired" in 2008 based on high levels of chlorophyll-a (the pigment component of common algae) found in water samples. Nutrients contained in stormwater runoff – primarily Nitrogen and Phosphorus – act as food for the algae. The nutrient-management plan developed and adopted for the Falls Lake Watershed severely limits the amount of Nitrogen and Phosphorus each acre of land in the watershed is allowed to contribute to the lake in any given year. The plan applies to all cities, counties and towns located in any part of the Falls Lake Watershed.
