Lancaster County – Final Notice for 8-step – Floodplain-Wetland (View Full Notice)

The Redevelopment Authority of the County of Lancaster is requesting the use of CDBG funding for acquisition of a 0.5-acre tract of land located in the 100-year floodplain for the development of a recreational trail facility to support the Borough of Marietta’s portion of the Northwest Gateway Trail.  There is potential impact in the floodplain with the proposed development of a recreation structure and parking.  The proposed project is located 421 West Market Street in Marietta, PA, Lancaster County.

 The County of Lancaster has considered the following alternatives and mitigation measures to be taken to minimize adverse impacts and to restore and preserve natural and beneficial values: Alternative locations for the project site are restricted based on the location of the existing trail and the developed Borough context. Because the trail adjacent to the project site is entirely located within the floodplain, any feasible site to be analyzed for alternative construction to serve trail users would have similar design constraints. The new structure will include markings to identify past and estimated flooding elevations, the structure will be constructed of masonry block or comparable material to save on flood insurance cost and to enhance the structure’s ability to withstand floods, will be placed at the maximum elevation practical within the design constraints of the site, and all construction will be elevated and consistent with FEMA’s Lowest Floor Guide.  All proposed development will be regulated at both a municipal level by Marietta’s 2014 Stormwater Management Ordinance and at a County/Commonwealth/Federal level by the Chapter 102 regulations related to Post Construction Stormwater Management.

The Marietta Restoration Associates is requesting the use of CDBG funding for the acquisition and demolition of a vacant, blighted structure on a 0.5-acre tract of land located partially in the 100-year floodplain.  The future use of the land will include public parking and greenspace to support two nearby public facilities.  There is a potential impact in the floodplain with the proposed construction of the parking lot.  The proposed project is located 1 N. Strawberry Ave, Marietta, PA, Lancaster County.

The County of Lancaster has considered the following alternatives and mitigation measures to be taken to minimize adverse impacts and to restore and preserve natural and beneficial values:  Alternative locations for the parking do not exist, given the density of surrounding proposed desirable Borough development and distances between historic venues and parking amenities. The lots which contain the historic structures are further constrained and unable to accommodate parking due to existing topography, limited site access, and an existing cemetery. The site will utilize a combination of traditional and pervious surfaces across the site, stormwater Best Management Practices will be implemented to ensure water quality and to mitigate drainage impacts. All proposed development will be regulated at both a municipal level by Marietta’s 2014 Stormwater Management Ordinance and at a County/Commonwealth/Federal level by the Chapter 102 regulations related to Post Construction Stormwater Management.
