Pier and Boardwalk Project
Rockland, ME
Coffin Engineering and Kleinschmidt were the site
work team for the project and were responsible for
site work and the marine structures for the new
office development on the shore of Rockland
Harbor. Coffin provided surveying, site and civil
design. Kleinschmidt designed the seawall and
boardwalk, rehabilitation of an existing granite
breakwater and a new pier and slips for the new site
facility. The project was completed in 2001, and
provides a public boardwalk connecting the City of
Rockland adjacent parks, and protected docking for
vessels of upwards of 100 feet.
The project included application for changes in flood zone mapping and site law permits. Kleinschmidt completed a coastal flood plain analysis in support of a Letter of Map Revision (LOMR) for redevelopment of coastal shoreline. A site-specific wave run-up analysis was conducted to define the flood and wave height elevation in the project area, in accordance with the methodology provided by the Federal Emergency Management Agency (FEMA) and the Army Corps of Engineers Shore Protection Manual to assess the impact of the proposed sea wall design and configuration. Three transects were developed along the proposed waterfront development site, one for each type of land/sea interface. Results supported a change in the FEMA zone designation, which was approved by FEMA. Construction of a seawall reduced the flood zone designation from its rating in the community Flood Insurance Rate Map (FIRM), and ultimately allowed continuance of the project.
