The tunnel will be enlarged from an average of 5 to 7 feet with the <br />installation of a new 24-inchconcrete encased pipeline. <br />Guida is providing the District with land surveying and mapping services to <br />support the stabilization and pipeline replacement. The surveying services <br />began with the establishment and verification of horizontal and vertical <br />controls both on the exterior and interior of the tunnel. Guida was also tasked with verifying the tunnel <br />alignment at the beginning of construction. During construction, Guida provide terrestrial HDAR (laser <br />scanning) of the interior of the tunnel to verify the tunnel alignment and create an as built of the tunnel and <br />newly installed pipeline. Additionally, Guida provided laser scanning to monitor the bluffs and monitor any <br />movement of the bluffs during construction activities. <br />Guida is currently providing monitoring of Bay Drive on top of the bluffs. Control was established outside the <br />area of influence by construction to monitor any potential movement that may occur to the street and homes <br />along Bay Drive. The monitoring is being performed on a regular basis with reports delivered to the District <br />after each monitor visit. Finally, Guida is providing legal descriptions and plats for new tunnel easements to <br />support the widening and acquisition of additional land for the tunnel improvements. These legal descriptions <br />and plats are being prepared over the 150 affected parcels by phase 2 and 3 of the tunneling project. <br />ADDITIONAL INFORMATION: <br />REFERENCE: <br />CLIENT: <br />South Coast Water District <br />South Coast Water District <br />31592 West St. <br />Laguna Beach, CA 92651 <br />Joe Si nacori <br />949.499.4555 <br />JSinacori@scwd.org <br />PROJECT FEE: <br />PROJECT DATES: <br />$201,500 <br />2018-Ongoing <br />a <br />PROPOSALTO <br />CITY OF SANTA ANA.
