HEAD /^7~jr~ CITY ATTY. (g&. CITYMGR. (iF-^ RECOMMENDED ACTION: Adopt Resolution No. 2010-002 approving plans and specifications and authorizing the City Clerk to advertise for bids for the Northwest Quadrant Storm Drain Improvement Program - Chestnut Avenue, Pio Pico Drive and Crest Drive, Project No. 6608. ITEM EXPLANATION: The Northwest Quadrant Storm Drain Replacement Program is a multi-year program to address non- master drainage plan needs within the northwest quadrant of the City. Carlsbad Operations and Maintenance staff was interviewed regarding their field observations and knowledge of drainage issues throughout the northwest quadrant. Site locations were identified and prioritized based on recommendations from field observations. The locations of the sites, status and current priority are included in Exhibit 2. Four sites are included in this contract request as shown on Exhibit 1. The Chestnut Avenue storm drain comprises two of the sites and will install 1,350 feet of 18-inch diameter reinforced concrete pipeline. The pipeline will carry nuisance groundwater, which surfaces in the street and currently flows in the gutter year round, to the existing storm drain system. New curb inlets and cleanouts will be installed. The project includes work within CALTRANS right of way, where Chestnut Avenue crosses under Interstate 5, and an encroachment permit has been obtained. The third site includes replacement of the existing storm drain located at the intersection of Pio Pico Drive and Forest Avenue. This existing storm drain is undersized and unable to convey storm water flow tributary to that location. The new storm drain system is designed to provide capacity to accept a 100-year flood event. The project includes the construction of 565 feet of reinforced concrete pipeline consisting of 105 feet of 18-inch diameter pipeline, 65 feet of 24-inch diameter pipeline and 395 feet of 30-inch diameter pipeline plus curb inlets, cleanouts and street surface improvements including reconstruction of 355 feet of concrete channel. The fourth site includes the Crest Drive storm drain improvement to replace a temporary system installed by City crews to protect the steep slope between Crest Drive and Monroe Street. The temporary system was situated on private property to convey storm flows. The new system will construct 150 feet of 18-inch diameter reinforced concrete storm drain pipeline and 380 feet of 18-inch diameter high density polyethylene pipeline through publicly owned land and convey the storm flows to the existing City storm drain system. The project includes construction of cleanouts and roadway improvements. In addition, 380 feet of the pipeline will be installed using a tunneling method referred to as "directional drill" to avoid surface impacts to Hosp Grove, thereby reducing environmental impacts.

FISCAL IMPACT: Table 1 shows the current status of the Northwest Quadrant Storm Drain Improvement Program. More specifically, the current status of the program shows the expenditures of previously completed storm drain improvements and the funds available to complete the storm drains in Chestnut Avenue, Pio Pico Drive, and Crest Drive: TABLE 1 - SUMMARY OF PROJECT EXPENSES FOR NORTHWEST QUADRANT STORM DRAIN IMPROVEMENT PROGRAM, PROJECT NO. 6608 TASK DESCRIPTION Design Construction, Inspection, Materials Testing Environmental Mitigation & Monitoring TOTAL APPROPRIATED TO DATE $482,228 $870,550 $21,100 $1,373,878 EXPENDITURES/ ENCUMBRANCES TO DATE $240,019 $0 $10,149 $250,168 REMAINING BALANCES $242,210 $870,550 $10,950 $1,123,710 An Engineer's Estimate of the construction cost for the Northwest Quadrant Storm Drain Replacement Program - Chestnut Avenue, Pio Pico Drive and Crest Drive project was prepared by Harris and Associates, the consulting engineer of work for this project, on August 20, 2009, and totals $1,175,000. The total estimated project cost is shown in Table 2. TABLE 2 - ESTIMATE OF PROJECT COST NORTHWEST QUADRANT STORM DRAIN IMPROVEMENT PROGRAM - PROJECT NO. 6608 Construction Contract (Engineer's Estimate) Construction Contingency (10%) Construction Management and Inspection (10%) Material and Geotechnical Testing During Construction (5%) TOTAL ESTIMATED CONSTRUCTION COSTS (CHESTNUT AVENUE, PIO PICO DRIVE AND CREST DRIVE) PROJECT AVAILABLE BALANCE ADDITIONAL APPROPRIATION ANTICIPATED FOR CONSTRUCTION ESTIMATED COSTS $940,000 $94,000 $94,000 $47,000 $1,175,000 $1,123,710 $51,290 The project is funded by both General Fund and Gas Tax Funds. Additional funds may be required but will not be determined until the bids are received and reviewed. If additional funding is needed then staff recommends appropriating the additional funds estimated to construct this project, and postpone design of the next scheduled drainage improvements listed for the Northwest Quadrant Storm Drain Improvement program until additional appropriations, as needed, can be made for the Page 3 program during the FY 2010-11 CIP. If additional appropriations are needed for this project then staff will return to Council and make that request along with the award of the construction contract. Constructing the projects using one contract is more efficient than separating the project into multiple contracts. The cost savings derived from bidding the projects as one contract are due to the similarity of construction techniques on each storm drain, the proximity of the projects to one another, and savings realized by ordering larger quantities of materials. Staff recommends approving the plans and specifications and authorizing the City Clerk to advertise for bids for the construction of Northwest Quadrant Storm Drain Improvement Program - Project No. 6608 for storm drain improvements in Chestnut Avenue, Pio Pico Drive, and Crest Drive.
