Preserving a Favorite Summer Destination
Lower Falls is the most popular destination on the Kancamagus Highway in White Mountain National Forest, New Hampshire. Located where the Swift River drops over smooth granite rocks into a large pool, it’s an ideal location for picnics, sunbathing and swimming.
But over time, the heavily-used site had a parking lot with significant stormwater management deficiencies. The lot was contributing heavily to the sediment build-up in the adjacent recreational river. The LA Group partnered with the US Forest Service to provide design and engineering services to redesign and reconstruct the parking area.
New stormwater management measures needed to meet state regulations. In addition, The LA Group introduced a new entry guard station and kiosk, rehabilitation of a CCC-era picnic shelter, and new picnic areas. The design also supported the improvement of trails, site accessibility, waterfront access, and introduced a new viewing platform. With all of the new work in place, forest revegetation can begin.
Scope of work included site analysis, hydraulic modeling of pre-development and post-development site conditions, stormwater management design to properly treat and discharge runoff, and full construction/bidding package, including drawings, specifications, cost estimates, and bidding manual. Scope also included permitting for NHDES Alteration of Terrain and Shoreland permits, NPDES Stormwater, and NHDOT Driveway Permit.
