From Sand Dollar Pump Station,water is then transmitted through a 20-inch line(consisting of twin 16-inch lines crossing the Packery Channel)to the NCWID#4 system. During a recent storm event,the 20-inch water line to NCWID#4 was damaged and water supply to the region from the City of Corpus Christi had to be halted. To avoid a similar situation in case of future storm/severe weather events,the City wants to take steps to improve the redundancy and reliability of the water distribution system in the area. In this regard, the City has requested that the following alternatives be evaluated to help the City determine the most feasible option to add redundancy and increase water distribution system reliability. • Option 1:Construction of 20-inch waterline from existing twin 16-inch waterlines(northside of the Packery Channel)to Zahn Drive. • Option 2:Construction of 20-inch waterline from existing twin 16-inch waterlines(southside of the Packery Channel)to Zahn Drive. • Option 3: Construction of 20-inch waterline from PK Road 53 (opposite Padre Island Burger Company)to Zahn Drive. • Option 4:, Construction of 20-inch waterline from PK Road 53 (opposite Padre Island Burger Company)to Fire Station No. 16. In addition,this task authorization will also evaluate the installation of a 4-inch conduit for fiber optics cabling to assist City MIS staff with connection of Fire Station 16 to the City's SCADA system. • Option 1:Construction of 4-inch fiber optics conduit from Sand Dollar Pump Station to Zahn Drive. • Option 2:Construction of 4-inch fiber optics conduit from Sand Dollar Pump Station to Fire Station 16. The purpose of this task authorization is to evaluate each of the above alternatives and provide recommendations for the material, depth and method of construction for the proposed waterlines and MIS conduits. In addition,this task authorization will also provide the Engineer's opinion of probable construction cost for each alternative. EXHIBIT A Page 2 of 6 LNV SCOPE OF WORK ADDITIONAL SERVICES: Task 0009—General Engineering The Engineer will perform the following: • Attend kick-off meeting with City staff to determine the objectives and requirements for the project. • Review existing plans,reports and easement information available for the proposed construction area. • Analyze options for waterline and MIS conduit construction listed above and provide the following information for each: o Proposed waterline length,material and depth o Proposed MIS conduit length,material and depth o Method of construction o Engineer's opinion of probable construction cost • Prepare a technical memorandum for City review. Notes and Assumptions: i. This memorandum will only present the method of construction, material of construction, proposed line depth and estimated construction cost for the different alternatives.Based on this information,the City staff will decide the most feasible alternative for construction. ii. The proposed water line and fiber optic conduit sizes are pre-determined by City staff. iii. It is assumed that the proposed water line and fiber optic conduit will be constructed within the existing City of Corpus Christi or Texas Department of Transportation(TxDOT)right-of-way. No additional cost is included in the estimates for acquiring land for easements; however, additional effort required to obtain permits for construction from TxDOT and US Army Corp of Engineers(USACE)is included in the cost estimates. iv. A new project for the dredging of Packery Channel is currently in the works.The information about the dredging including proposed depth of dredging was provided by City staff. Depths for the proposed waterline and fiber optic conduit is based on the new proposed depth of the channel. v. It has been noted by the City that the capacity of the Sand Dollar Pump Station will need to be increased to meet any future large water demand from NCWID#4.Since the future demand has not been evaluated under this scope,the cost for modifications of the Sand Dollar Pump Station has not been included in the cost estimates shown in this memorandum.
