CITY ENGINEER cf DATE: MARCH 18, 1992 (Meeting of 3- 25 -92) All SUBJECT: AUTHORIZATION TQ ADVERTISE FOR THE RECEIPT OF BIDS FOR THE CONSTRUCTION OF THE CHARLES STREET AND STORM DRAIN AND SIDEWALK IMPROVEMENTS (PHASE I) BACKGROUND �02PA4K, CALL "C ?;%, Ciiy Council Mee;.,-)g 199 0) Last Summer the City Council considered design options (overlay, reconstruction, etc.) for the improvement of Charles Street. At that time staff was directed to-proceed with a project design for the reconstruction of Charles Street in a manner which retained as many trees as possible. The project design developed with input from the Public Works / Facilities Committee. With the Committee's recommendation, the final draft design was reviewed and approved by the City Council on November 6, 1991. The limited funds available do not permit the construction of the entire project at this time_ The project has, therefore, been separated into phases. Phase I construction will extend from Moorpark Avenue to a point just east of Bard Street. Further details on the design criteria is set forts: in the November 6 report. NOTE: The engineering plans for this project will be distributed to the City Council under separate cover. DISCUSSION The storm drain plans include the installa-ion of 24" and 34" reinforced concrete pipe between Bard St. and Walnut St. This drain includes catch basins and appurtenant laterals to improve collection of the surface run -off. The new storm drain: will tie into the existing 71x 6' reinforced concrete box drain, at Walnut St. PAUL W. LAWRASON JR. BERNARDO M. PEREZ SCOTT MONTGOMERY R:Y E. TAL_' JR_ JOHN E. WOZNIAK Mayor Mayor Pro Tern CounoWnember :ounclme —cer Councilmember Charles Street Page 2 Street improvements include: new curb & gutter, sidewalk, cross gutters, new handicap ramps, new driveway aprons, striping, tree wells and root guards, and the relocation and adjustment of in- terfering utility structures. Some key project design elements are discussed in more detail as follows: 1. Due to the elevation difference from the north parkway to the south parkway, different curb heights are proposed. The northern curb will be 8" high and the south curb will be 6" high. The cross slope of the street will also be different on the north side than the south side. To provide positive drainage to the gutters from both the centerline of the street and from the parkways, the cross slope of the north side of the street will be 1.5% and the south side will range from 2%- 3.4 %. This is in the range of acceptable practice in such conditions where common elevations on each side of the street are not feasible. 2. The design attempts to salvage all trees where practical. Two trees however have been targeted for removal because of conflicts with the improvements. Five new trees are to be planted as shown on the plans. Tree wells and mounding of earth around the trees is required where elevations are a problem. It is also necessary to bend the curb around one very large tree in front of 171 Charles St. to salvage the tree. (Some tree trimming and perhaps even additional tree removals may be required if root pruning, required for the improvements, impair the health of the trees.) FISCAL IMPACT A. Proiect Cost Estimate: The following is a summary of the estimated total project costs allocated to proposed funding sources. Element Total ($) Design (Prior Expense) 39,550 Construction 275,000 Constr Admin & Insp 30,000 Sub- Total 344,550 Contingency (10%) 34,450 Total 379,000 r Charles Street Page 3 B. Project Funding: • CDBG -- The City has allocated a portion of its CDBG funds for the construction of street improvements. Expenditures to date include the construction of handicap access improvements throughout the City and a portion of the Avenida Colonia/ Nogales street improvement costs. The amount of street improvement CDBG funds remaining is $140,926. It is recommended that this amount be used on the Charles Street project. In addition, it is recommended that a portion of next year's CDBG appropriation be used on this project (see Gas Tax). Gann -- The amount of Gann funds available for street improvements is $250,000. The direction of the City Council was to first use these funds for planned improvements on Avenida Colonia /Nogales, with the remainder to be used for improvements to Walnut Street and Charles Street. The amount of funds required for the Avenida Colonia /Nogales project was $115,527, leaving a balance of $134,473. With the deferral of the Walnut street improvements, it is recommended that these funds be directed toward the Charles Street project. • Transfer of Funds -- As a separate matter, the City Council is being requested to consider approving the allocation of $50,000 in Gann funds to the Boys & Girls Club in exchange for the early repayment of a $50, 000 loan from the CDBG fund. If approved, the amounts of available Gann and CDBG funds mentioned above would be adjusted upward and downward by said amount, leaving the net funds available for the Charles Street project unchanged. The net result of this action will be the allocation of a larger amount of CDBG funds for an existing project. Staff is in support of this action in that it reduces the number of projects encumbered by CDBG regulations. Gas Tax -- The remainder of the project funding would come from the Gas Tax fund. At present only $55,000 in Gas Tax funds has been appropriated for this project. An additional appropriation (approximately $50,000) will be required to completely fund the project. It is recommended, however, that a portion of next year's CDBG funds be used for this project. If approved, this will reduce the amount of Gas Tax required. Staff recommends that the funding source for this additional appropriation be deferred until the 1992/93 CDBG allocations are determined by the City Council. Charles Street Page 4 PROJECT SCHEDULE The scheduling of the Charles Street improvements have been programmed to begin after the High Street project is completed. The Charles Street project is planned to start in June and be completed in September. RECOMMENDATION It is recommended that the City Council take the following action: 1. ApRrove the project design plans. 2. Direct staff to seek and obtain (City Staff effort) private construction easements where required; 3. Defer the appropriation of additional funds until the award of contract; and, 4. Authorize staff to proceed with advertisement for receipt of bids for the subject project. wp \chas
