The proposed project would involve demolition of existing groundwater monitoring wells and installation of new wells by Solar Turbines Inc. (Applicant) in the City of San Diego, California. Work to specifically complete the proposed project would involve
demolition of seven (7) groundwater wells within the existing Solar Turbines Inc. parking lot adjacent to Harbor Drive. The Applicant also proposes to install eight (8) groundwater monitoring wells within the public Right-of-Way (ROW) including sidewalk area and three (3) parking areas on the bayside of North Harbor Drive using a combination of bailing, surging, and purging. The monitoring wells would be constructed of 4-inch diameter schedule 40 polyvinyl chloride (PVC) well casing and screen. Each well would be constructed with screens targeted to be approximately 50 to 70 feet below ground surface (bgs) and 70 to 90 feet bgs. The wells will be completed flush to the ground surface with a traffic-rated protective well box that will be cemented in place.
Construction of the proposed project is anticipated to occur in Summer 2020 and would take approximately six (6) weeks to complete; new well installation would take approximately four (4) weeks to complete and would be conducted in three phases within each of the three ROW areas, and demolition of the existing wells would take approximately two (2) weeks to complete. The first phase would take place at the northernmost ROW and would require closure of the parking area for one (1) week; approximately twenty-seven metered spaces, two ADA spaces, and one permit space would be closed during the first phase. The second phase would be at the central ROW area and would require closure of the parking area for two weeks; approximately six metered spaces, one ADA space, and two permit spaces would be closed during the second phase. The third phase would be at the southernmost ROW area and would require closure of the parking area for one week; approximately eleven metered spaces would be closed during the third phase. In addition, a traffic lane on North Harbor Drive ROW adjacent to each phase area would be closed during construction of each phase in accordance with a project-specific Traffic Control Plan that establishes construction striping, barricades, signage, delineators, additional traffic controls, lane closures, constructor requirements, and contractor notifications in compliance with 2014 California Manual on Uniform Traffic Control.
Due to its nature and limited scope, construction of the proposed project would generate a minor amount of vehicle trips and would require limited use of equipment. Therefore, significant impacts related to air quality, greenhouse gas emissions, and transportation and traffic are not anticipated to occur. Furthermore, the Applicant would be responsible for complying with all applicable federal, state, and local laws regarding construction demolition debris, hazards and hazardous materials, and stormwater.
The proposed project would also require a Right of Entry License Agreement (ROELA) to the Licensee to enter certain properties located in the City of San Diego, California. The area proposed for use under this ROELA would be used by the Licensee and their authorized agent(s) and contractor(s) for the purpose of installation of eight monitoring wells, groundwater sampling, testing, monitoring, future installation and abandonment of monitoring wells within the project area, as well as ingress and egress in support of those activities.
It is anticipated that the ROELA would have a total term of five (5) years, or upon completion of the work, whichever occurs earlier. The ROELA may be terminated by the District as a matter of right and without cause at any time upon providing twenty-four (24) hours' written notice to Licensee of such termination.
