HUSTON, CITY MANAGER PUBLIC WORKS DEPARTMENT/WATER SERVICES DIVISION APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE FOR BIDS FOR THE ANNUAL SIDEWALK AND CURB & GUTTER REPAIR PROJECT FY 2000-2001 (PROJECT NO. 402-6235) SUMMARY This project provides for removal and replacement of sidewalk and curb and gutter, drive aprons and parkway trees at various locations throughout the City to correct tripping hazards. This project will also provide for the addition of new sidewalk at certain locations in the City where there is no existing sidewalk. RECOMMENDATION It is recommended that the City Council adopt Resolution No. 00-70 approving the plans and specifications for the Annual .Sidewalk and Curb and Gutter Repair Project FY 2000-2001 and authorizing and directing the City Clerk to advertise for bids. FISCAL IMPACT The engineer's construction contract estimate is $129,000.00 and the City's Public Works Department/Engineering Division Operating Budget (Account No. 01-402-6235) provides sufficient funds to cover all of the costs associated with this annual project. This work is part of the City's on-going Maintenance of Effort requirements for compliance with Measure M. BACKGROUND This project provides for the removal and replacement of concrete sidewalk, curb and gutter and drive aprons to correct tripping hazards at approximately 135 locations throughout the City. Some of the areas slated for sidewalk replacement have been reconstructed at least once during the last 5 years. Recurring damage to sidewalks can be attributed to roots of adjacent parkway trees uplifting the sidewalk. Wrth the aid of a consultant Arborist, the Engineering Division has conducted a survey and analysis of 14 locations where tree roots are causing sidewalk damage. The analysis, entitled "Tree Removal and Replacement Recommendations" dated October 2000 (attached), concludes that 10 of the existing street trees analyzed are no longer appropriate for the width of the parkway or tree well they lie within. These trees will continue to cause damage in the future to the adjacent sidewalk and/or curb and gutter, resulting in recurring sidewalk and/or curb and gutter replacement costs, and will be removed with the FY 2000-2001 project. Annual Sidewalk and Curb and Gutter Repair Project, FY 2000-2001 (Project No. 402-6235) October 16, 2000 Page 2 Trees to be removed with this project will be replaced either in kind or with a species more suitable to the parkway area available. The City's Tree Maintenance contractor will perform the tree removals and replacements as managed by the Field Services Division. The Annual Sidewalk and Curb & Gutter Repair Project FY 2000-2001 will fund the tree removals and replacements. The other major function of this project is to provide a means for addressing improvements throughout the City to comply with the Federal Americans with Disabilities Act (ADA). These locations are typically requested by citizens and/or are identified by City staff to provide for completion of missing segments of sidewalk to improve disablsd/pedestrian access. ADA related improvements slated for this year's project includes construction of three segments of concrete sidewalk including the north side of Warner Avenue frOm Red Hill Avenue to 1800' west of Red Hill Avenue, the west side of Pacific Street from Third Street to 200' north of Third Street and at 15600 Williams Street. These areas currently have only limited stretches of sidewalk, and construction of these missing segments will eliminate the need for pedestrians to traverse these zones on the side of the road adjacent to vehicular travel lanes. The tentative schedule for this project is as follows: Authorization to Advertise for bids ........................................................................... 10/16/00 First Legal Advertisement ....................................................................................... 10/26/00 Second Legal Advertisement ........................................................................ - ........ 11/02/00 Bid Opening ............................................................................................................ 11/29/00 Award of Contract .............................. : .................................................................... 12/18/00 Commence Construction ........................................................................................ 01/29/01 Complete Construction .......................................................................................... 04/09/01 Director of Public Works/City Engineer Associate Civil Engineer TDS:JO:ccg Advertise Sdwk and C&G Repair Project 00-01 .doc Attachments Resolution No. 00-70 Tree Removal and Replacement Recommendations - October 2000 6 ~0 RESOLUTION NO. 00-70 A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF TUSTIN, CALIFORNIA, APPROVING PLANS AND SPECIFICATIONS FOR THE ANNUAL SIDEWALK AND CURB & GUTTER REPAIR PROJECT FY 2000-2001 (PROJECT NO. 402-6235), AND AUTHORIZING ADVERTISEMENT FOR BIDS WHEREAS, it is the intention of the City Council of the City of Tustin, California to contract construction of the Annual Sidewalk and Curb & Gutter Repair Project FY 2000-2001; and WHEREAS, the City Engineer has presented plans and specifications for the construction of said work; NOW, THEREFORE, BE IT RESOLVED that the plans and specifications presented by the City Engineer be, and are hereby approved, as the plans and specifications for: Annual Sidewalk and Curb & Gutter Repair Project FY 2000-2001 (Project No. 402-6235).

SUMMARY The purpose of this report is to analyze potential savings opportunities for the City within the Public Works Department's Annual Sidewalk and Curb & Gutter Repair Project. This project locates areas within the City where tripping hazards have been created by damaged or lifted sidewalk. Many of these repair locations are recurring due to tree roots affecting the sidewalk even after root pruning treatments. Removal and/or replacement of some of the trees that have become too large'for the parkway or tree well that they are in will benefit the annual program in the long run. The program will benefit by not having to replace the same areas of sidewalk every few years. The City has retained an Arborist to survey and analyze 14 problem trees. The analyses note the location, size and species of the trees, as well as evaluate root pruning options and length of time before the roots heave the sidewalk again. These evaluations are found in the "Tree Analyses" section of this report. The analyses include map and location numbers, which refer to the maps supplied in the "Location Maps" section of the report. With the aid of the tree analyses, the Engineering Division has determined which trees are unfit for the parkway or tree well size that they are in and which trees will continue to harm the adjacent sidewalk until removed. Ten out of the 14 trees analyzed have been chosen to be removed and replaced with new trees in this year's .- project a~ a cost of $2,600 for removals and $1,600 for replacements. The total cost for reconstructing the sidewalks at those 10 locations this year is $4,200. This cost would be recurring at approximately 3- year intervals according to the Arborist's analyses. For tree locations as well as costs associated with removing/replacing trees and reconstructing sidewalk, please refer to the following table- "Tree RemoVal and Replacement Recommendations".
