Environmental Restoration, Stormwater Retrofit and Stormwater Outfall Infrastructure Rehabilitation Program
Project Description
This program is intended to provide rehabilitation of existing stormwater outfall infrastructure and install stormwater retrofits in conjunction with environmental enhancements of natural resources at various Parks throughout Montgomery County.
Background
During storm events, larger than natural volumes of stormwater will rush into local streams in areas with a lot of impervious surfaces (roadways, parking lots, buildings). This can cause significant damage to habitat and other features within a stream. Stormwater management uses techniques and practices to slow, soak in, or store stormwater and help reduce the amount of pollution entering our waterways. Stormwater management facilities reduce the volume and intensity of water that rushes into streams by providing an area for short-term storage of stormwater. The stormwater will slowly soak into the ground, mirroring a more natural environmental system. Stormwater retrofits are the installation of stormwater management facilities to treat existing impervious surfaces that were originally installed without stormwater management techniques.
Stormwater outfalls (locations where concentrated flows of stormwater are released back into nature) are located throughout our Park system. Due to impervious surfaces upstream, the stormwater often enters our Parks at high velocities, causing erosion and degradation of our stream valleys. By using ‘green’ techniques to repair these eroded outfalls in our stream valleys, we can protect both natural areas and infrastructure (trails, playgrounds, recreational open space, athletic fields, etc) from flooding, erosion, and degradation. This strategy keeps our facilities safe while improving habitat and ecological function.
Currently, this program is funded to address several prioritized projects each fiscal year in order to eliminate these hazardous conditions while enhancing our natural environment.
