SSFM’s scope included preparation of construction drawings, specifications, estimates of probable construction costs, and construction administration. It also entailed preparation of an Environmental Assessment and U.S. Army Corps of Engineers Permit, Conservation District Use Permit, Shoreline Setback Variance, Special Management Area Permit, UIC Closure Permit, and NPDES Form C and Form G permits.
