Concepts for protecting water resources

Low Impact Development

Water Resources
East Tennessee Water Resources
Water resources are abundant here at the headwaters and upper tributaries of the Tennessee River, and they have helped define the region socially, economically, and environmentally.
Current Stormwater Management Practice
Current Management Practice
The current method of managing stormwater relies heavily on detention and retention with controlled discharges of stormwater to local waterways.
Curbside Raingarden
Curb-cuts along this road allow water to infiltrate and contaminants from the runoff to be filtered before reaching municipal stormwater infrastructure or a local body of water. These landscaped areas are aesthetically pleasing and can contribute to increased property values of neighborhoods.
Green Infrastructure
Green Infrastructure Opportunities
From small-scale projects such as home raingardens to large-scale regional efforts such as greenways and land trusts, these coordinated efforts are deemed green infrastructure and work to protect water quality.
Agricultural Best Managment Practice
Agricultural Best Management Practices
Agricultural BMPs can address non-point water quality issues that stem from agricultural activities, such as sedimentation from livestock walking through streams, topsoil erosion, and runoff of fertilizers, pathogens, and pesticides.

About this Project

East Tennessee’s iconic water resources are a sustaining economic, social, and environmental asset. These resources are vulnerable to impacts from prevailing development patterns in the region, human activities, and existing stormwater infrastructure. Each increase the quantity of polluted stormwater runoff draining to region’s streams, rivers, reservoirs, and groundwater resources, compromising their health and the health of the communities they sustain. With the Plan East Tennessee Region’s population poised to grow forty-three percent by 2040, reliance upon these water resources will increase while their health is further threatened by expanding development. Low Impact Development methods proposed in this publication off er existing and expanding communities an enhanced approach to watershed planning, community design, and site development that avoids, minimizes, and manages impacts to the region’s shared water resources.
