NIH, MoCo Stormwater Pond Entering Final Stages

Montgomery County is nearing the completion of an expansive pond on the NIH campus that environmental planners say will treat stormwater from downtown Bethesda and NIH that might have otherwise ended up in a tributary of Rock Creek.

The county started construction on the $2.5 million, six-acre Stoney Creek Stormwater Management Pond and site in October 2010. Construction was scheduled to last two years.

The project, which includes a 1.3-acre pond, two underground trash collection chambers and landscaping near the intersection of Wisconsin and Woodmont Avenues, is approaching its final stages, according to county spokeswoman Esther Bowring.

Bowring said the county will complete all site grading and construction by early March, at which point planting will begin. There will be periodic follow-ups as required to get the new grasses, shrubs and trees off to a good start.

The county regarded the location of the pond as key for capturing runoff from 204 acres of the Bethesda Central Business District and NIH campus. The project will also include a subsurface aerator for enhancing water circulation and other measures for discouraging mosquitoes or other pests.

The site sits on the southern edge of NIH’s campus, directly behind the apartments on Battery Lane.
