Mgr: -- 4 - DEPARTMENT : I . Subject: COASTAL BICYCLE ROUTE - FINAL DESIGN - CONTRACT NO. 1061 Statement of the Matter Plans and specifications for the Coastal Bike Route have been com- pleted by the consulting firm of Plohle, Perry and Associates and have incorporated all the concerns of the Traffic Safety Commission and the Engineering Department. The consultant has estimated that the construction will cost approxi- mately 50% more than the original estimates due to the considerable road work that will be necessary to modify curb grades and eliminate drainage problens along Carlsbad Boulevard between Walnut and Tamarack Avenues (see memorandum dated December 26, 1978). The City Council endorsed the preliminary design on June 6, 1978. Exhibits 1. Traffic Safety Commission minutes from June 5, 1978 meeting. 2.

Local Transportation Funds (LTF) and an additional $14,000.00 from CalTrans (Bicentennial Bike Route). Funds in the amount of $34,000.00 have been previously budgeted from gas tax funds as the City's local share of the project. This project has received a grant of $190,492.00 from The current engineer's estimate for this project is $333,700.00 (see attached). estimate, on which our LTF grant funds were based. caused the cost estimate to escalate. trend of construction costs in general, the detailed engineering design has shown the need for significant reconstruction and overlay of Carlsbad Boulevard, north of Tamarack. Additionally, the current design includes significant storm drainage systems to correct street grades and water pond- ing on the Boulevard. The current estimate is considerably higher than the initial Several factors have Besides the recent inflationary Based on the current engineer's estimate, approximately $115,000.00 of additional funds will be required to complete the project. The actual low bid will determine the amount of additional funding required. Potential source of funding could be unappropriated reserves of the General Fund, Gas Tax Funds, or a combination from both funds. at this time, using General Funds that have been budgeted for other projects. A recommendation as to funding sources will be made to the Council after the bids are reviewed. I do not propose, One additional problem that has not been resolved concerns the reconstruc- tion of several intersections along Carlsbad Boulevard. The project is designed to revise the curb line at the intersections to provide for a safer turning movement, and to provide for the wheelchair ramps (see attached sketch). within the existing public right-of-way, additional right-of-way will be required at each intersection in order to have standard width and con- tiguous sidewalks. Some, but not all, right-of-way has been obtained. While construction of the curb line can be accomplished I propose to construct the curb line at its ultimate location at all the intersections and to construct the sidewalk and wheelchair ramps at those locations where right-of-way has been obtained. It is further proposed that the City continue efforts to obtain the remaining right-of-way in order to provide for the City to construct the full improvements now rather than later, possibly at property owner expense. It is recommended that the City Council approve the plans and specifica- tions for Contract No. 1061 (Coastal Bike Route) and authorize the City Clerk to advertise for bids to be opened at 4:OO p.m. on April 17, 1979.

Adding a 10% contingency factor to the total amount, the consultant has esti- mated the construction to cost $333,700. This is more than a 50% increase from the original estimate primarily due to the considerable road work that will be necessary to modify grades (and el iminate drainage problems) along Carlsbad Boulevard between Walnut and Tamarack Avenues. The cost of the design itself was $19,400 plus $1,895 for additional drainage system design. The following funds are available: $190,492 from LTF funds (in Bicycle Lane Account at CPO) 14,000 from CALTRANS funds (Bicentennial Bicycle Route monies) 34,000 from City Revenue Sharing $238,492 total - Therefore, there is a deficit of $114,608 that will need to be made available in order to cover all the construction cost outlined by the consultant. Other factors (e.g. , inflation) have increased the construction cost estimates; however, as noted earlier, the primary reason is all the reconstruction of Carlsbad ' Boulevard (from Walnut to Tamarack Avenues) necessary to improve drainage faci 1 ities (at a minimum curb grade of 0.3%). I recommend that the funds ($101,000) budgeted for storm drains on Sycamore, Chestnut and Maple Avenues be considered as a source for additional funding. There are also a few items in the construction proposal that could be eliminated (e.g., some guardrail replacement) that would help lower the project cost. At this time I recommend that the consultant's final design of the Coastal Bi- cycle Route be sent to City Council for approval. struction as soon as possible since both the Coastal Commission permit and the agree- ment for CALTRANS funds ($14,000) both terminate on July 1, 1979.
