South Road Mitigation Site (Site #14 and #15) is an advanced mitigation site comprised of an approximately 75 acre collection of three lots located west of the Londonderry/Derry border near the intersection of South Road and Gilcreast Road in Londonderry. The site borders Beaver Brook which is a designated Conservation District pursuant to local ordinances in Londonderry. Large portions of two of the lots were privately-owned gravel pits until purchased by NHDOT, with the potential to become residential development. The third lot is mainly wetlands associated with Beaver Brook. Principal wetland functions and values expected to be provided by the site include groundwater recharge/discharge, fish and shellfish habitat, sediment retention, and wildlife habitat. Situated on Map 7 of the Londonderry lot and parcel maps, the three lots are identified as: Lot 111 (24.4 acres), Lot 113 (38.0 acres), and Lot 114 (12.8 acres). An estimated 11 acres of creation and/or enhancement and approximately 64 acres of preservation will be provided by the site. Design of wetland areas has been completed.
