Sea Lane, Old Saybrook, CT
Indigo was retained by the property owners of 26 & 30 Sea Lane #1 in the Cornfield Point section of Old Saybrook to provide civil engineering design and construction coordination services for a 130-foot long cast-in-place reinforced concrete seawall with terrace and a 75-foot long grouted rip-rap stone slope revetment. A cast-in-place stairwell to provide access from the lawn area to the cobblestone beach below was also incorporated into the design. The pre-existing seawalls and rip-rap were severely damaged during Super Storm Sandy in 2012 and needed timely replacement to avoid continued sloughing of lawn areas above and encroachment of erosion toward the homes. Challenges included failed seawalls and slopes on adjacent properties, creating two separate retaining structures to act as one continuous structure and logistics during construction due to a narrow working environment and the immediate proximity of sensitive coastal resources.
