ENG /,.m. - i --A! 9 5 5 CITY OF CARLSBAD - AGENDA BILL ’ / - TITLE: APPROVAL OF AMENDMENT NO. 2 TO AGREEMENT WITH CAMP DRESSER & MCKEE INCORPORATED FOR ENGINEERING DESIGN SERVICES FOR THE SOUTH AGUA HEDIONDA INTERCEPTOR SEWER, REACH SAH3; CMWD PROJECT NO. 92-406; CITY PROJECT NO. 35831 DEPT. HD. CITY ATTY. CITY MGR. RECOMMENDED ACTION: Adopt Resolution No. -330 approving Amendment No. 2 to Agreement with Camp Dresser & McKee Incorporated for Engineering Design Services for South Agua Hedionda Interceptor Sewer, Reach SAH3; CMWD Project No. 92-406; City Project No. 35831. ITEM EXPLANATION: Adoption of Resolution No.&!~-~~will redirect the efforts on the design of the Agua Hedionda Interceptor Reach SAH3 towards studying alternative sites for the lift station and recommending a location that can potentially reduce the impacts to the environment and the construction cost of the project. Based on the recommended site, odor and noise modeling, geotechnical investigation and environmental assessment shall be performed in preparation for design. The City Council adopted Resolution No. 99-479 on November 2, -1999, approving the selection of Camp Dresser & McKee Incorporated (CDM) to provide final engineering design services for the South Agua Hedionda Interceptor Reach SAH3. The original scope of work consisted of preparation of construction drawings and contract documents and providing construction support. The cost for such effort was in the amount of four hundred sixty thousand, three hundred forty eight ($460,348) dollars. The project was separated into two phases. Phase 1 involved developing construction plans and bid documents related to site rough grading and construction of the force main. Phase 2 consisted of preparing plans and bid documents for the construction of the lift station and influent sewer. Horizontal directional drilling (HDD) across the Agua Hedionda Lagoon and microtunneling from Cannon Road to the lift station wet well were proposed as construction methods for installing the force main and influent sewer, respectively. At 50% design of Phase 2 and 90% design of Phase 1, CDM presented the City with an engineering estimate of the construction cost for both phases that was $2.7 million dollars more than previously estimated at predesign. The increase was mainly due to costs not considered ,during predesign, including environmental constraints, incorporation of safeguards to reduce horizontal directional drilling mishaps and to prevent sagging of the influent sewer, and providing 100 percent pumping redundancy. In light of the increased cost, the Engineering staff re-evaluated the project and began investigating alternatives. Preliminary cost estimates were developed that showed a significant reduction in construction cost if the lift station was located along Cannon Road, and constructing the force main within the Cannon Road right-of-way and utilizing a parallel 14-inch ductile iron pipe already incorporated into the Cannon Road Bridge. The use of conventional open trench construction of the force main and influent sewer, reduced wet well depths, and reduced influent gravity sewer depths are major factors in the cost reduction. Although alternatives involving alignment of the force main along Cannon Road have higher energy requirements, the twenty-year life cycle cost of these alternatives were up to $2.8 million less than the original alternative involving HDD and microtunneling. The relocation has also received support from the California Department of Fish and Game (Exhibit 4). Page 2 of Agenda Bill No. I;!Wb The results of this preliminary analysis triggered interest in a more refined alternatives analysis that includes, at a minimum, review of environmental impacts, easement requirements, constructability, site layout, and pipe and pumps selection. Staff has instructed CDM to halt progress on the design of the Cannon Road Lift Station and recommends that the remaining funds in the CDM contract, which total two hundred twelve thousand, nine hundred six ($212,906) be used to direct CDM to investigate alternative sites and other activities described in the attached Amendment No. 2. CDM would provide the best service because of their familiarity with the project. ENVIRONMENTAL REVIEW: At its April 19, 2000 meeting, the Planning Commission adopted Planning Commission resolution No. 4760 approving a Mitigative Negative Declaration and Mitigation Monitoring and Reporting Program and adopted Planning Commission Resolutions No. 4761, 4762, and 4763 approving a Conditional Use Permit (CUP 99-19), a Hillside Development Permit (HDP 00-03) and Special Use Permit (SUP 00-03) for the original project. Since the focus of the study is to identify the alternative site with least environmental impact and cost, it is expected that the project will receive similar approvals. No advertisement for construction will be issued until the proposed Mitigated Negative Declaration is approved and Resource Agency permits are acquired for the final selected alternative. FISCAL IMPACT: Approximately $3.4 million has been appropriated for Phase II of the South Agua Hedionda Interceptor Reach SAH3 project and no additional appropriations are required for Amendment 2 to the Agreement for engineering design services. FUNDING SUMMARY FOR SOUTH AGUA HEDIONDA INTERCEPTOR REACH SAH3 Appropriation to Date $3,395,493 Expended to Date $ 672,548 Amount Available $2,735,008 Amount Requested for this Project $212,906 Remaining Balance $2,510,039 ADDITIONAL APPROPRIATION 0 This agenda bill is addressing only the design services needed to determine the most cost-effective way to construct reach SAH3, which is part of the overall South Agua Hedionda Interceptor Sewer project. This reach is necessary to provide sewer facilities for new development in Sewer Benefit Areas C, D, E, and F, and to provide facilities for existing developments currently using temporary sewer facilities pending the construction of SAH3. Funding for the entire South Agua Hedionda Interceptor Sewer project (including reach SAH3) is currently under review. Total costs for the project have not been determined. Staff will return to the City Council at a later date with estimates of the overall project cost and funding sources. EXHIBITS: 1. Location Map 2.

June 28,200O Mr. Victoi Ociano Associate Engineer City of Carlsbad 163 5 Faraday Avenue Carlsbad, CA 92008 Regarding: Sewer Pump Station Project, Agua Hedionda Lagoon Dear Mr. Ociano: In has come to the attention of the Department of Fish and Game (Department) that there is a biologically superior alternative to the current sewer pump station project’planned within thk Agua Hedionda Lagoon, City of Carlsbad, San Diego County. Although the Department has reviewed and prepared comments regarding the Proposed Negative Declaration for the South Agua Hedionda Interceptor Reach 3, City of Carlsbad (SCH#200003 1019), we strongly recommend that the City pursue the relocation of the sewer facility to the east of Cannon Road. As you are aware, the Department will soon be accepting the dedication of 186 acres of Agua Hedionda Lagoon adjacent to Cannon Road which is anticipated to include an easement for the proposed sewer facility site. The land will be designated as an Ecological Reserve and will be managed for the protection of wetland and upland resources that exist on the property. The potential for mechanical failure of pump facilities continues to concern the Department as well as the apparent need for improvement of existing dirt roads to the facilities for maintenance activities. Unfortunately, these access roads also allow the general public to access the sensitive marsh habitat areas, causing habitat degradation and harm to endangered species. It is the Department’s intent to eliminate unnecessary vehicular access, which would be easier to control if the sewer facilities were not placed in their proposed location. Although City engineering staff has been helpful in identifying potential alternatives to asphalt road paving, none of the discussed alternatives will address the runoff issues described in our comment letter dated April 3, 2000. Relocating the facility and its associated infrastructure outside of the lagoon and into a location already developed or proposed for development is a more suitable alternative. Because Cannon Road construction is expected to continue this fall, the Department requests a timely decision on the relocation of the sewer line so that any engineering and the construction for the sewer facilities can be incorporated into the road as necessary. This would avoid undue expenses or further time delays in addition to being environmentally superior. Mr. Ociano June 28,200O page 2 of 2 Please contact the Department if a meeting is in order to discuss this issue further, or if there are any questions. Please feel free to contact Ms. Kimberly McKee-Lewis at (858) 467-4222. Theresa A.
