Cumberland County Conservation District selected Herbert, Rowland & Grubic, Inc. (HRG) to design a Best Management Practices (BMPs) Demonstration Park around the existing Cumberland County Conservation District office site. The BMPs were to serve two purposes. The first purpose was to improve water quality and provide additional infiltration of existing stormwater runoff and the second was to educate the general public, school children, and visitors of the Demonstration Park about the roles, benefits and uses of stormwater BMPs.
HRG was responsible for the selection of appropriate BMPs, layout, design, cost estimating, project manual preparation, assistance with the bidding procedure, construction administration, and construction observation.
The constructed (retrofitted) BMPs include porous asphalt, pervious concrete, infiltration systems, rain gardens, snout, pervious pavers, vegetated swale, bioretention area, timber check dam, rip-rap apron, weir repair and stairs and observation platform.
Funding for the project was secured from a County Initiative Growing Greener Grant. Due to the limited budget available and the desire of the client to include as many BMPs on the site as possible, HRG was able to negotiate with suppliers on behalf of the client to get a number of the BMPs donated at no cost in order to enhance the overall success and effectiveness of project.
