COMMUNITY DEVELOPMENT DEPARTMENT MEMORANDUM October 20 , 2015 The Honorable City Cou ncil Bryan Cook , City Manager By: Michael D. Forbes , Community Development Director ~ A li Ca yir, PE , City Engineer PROGRESS UPDATE ON PAVEMENT MANAGEMENT PROGRAM IMPLEMENTATION RECOMMENDATION: The City Counci l is requ ested to rece ive and file the progress update on imp lementation of the Pavement Management Program (PMP) and prov id e comments and direction to staff as appropriate . BACKGROUND: In 2013 , Temple City's PMP Report was comp leted by Harris and Associates. The Executive Summary of the report is attached as Attachment "A ". ANALYSIS: Th e PMP Report prese nts findings and recommendations from the pavement condition s urvey of Temple City's street network, including pavement condit ion summaries , preservation and repair activities , and projected budgets for those activities . As stated in t he report , the recommendations are for planning purposes o nly and are not intended to rep lace sound eng ineering judgement for actual const ru ction. Pavement Condition Ind ex : The PMP Report rates the condition of streets based on the Pavement Condit ion Index (PC I) system . Th e PCI is a rating mechanism used to describe the condition of pavement and has been adopted by the American Association of State Highway and Transpo rtation Officials (AASHTO) and the American Society for Testing and Materials (ASTM ) as the nation al standard pavement rating system . PCI ratings range from 0 to 100 , where a PCI of 0 corresponds to badl y deteriorated pavement with virtually no remain in g l ife and a PCI City Council October 20 , 2015 Page 2 of 3 of 100 corresponds to pavement with proper engineering design and construction at the beginning of its life cycle . Cond ition of Temple City's Pavement: Per the PMP Report , the overall average condition of Temple City's street network is "Good ", w ith an average weighted PCI of 62 . Arterial streets are considered "Very Good " with a PCI of 77 , collector streets are "Good " with a PCI of 59 , and resident ial streets are "Fair" w ith a PCI of 54 . Replacement Value and Quantity of Pavement: Temple C ity has approximately 71 miles of paved streets and alleys , including 10 miles of arterial streets , 39 miles of co llector streets , 19 m iles of residential streets , and three miles of alleys . This equates to about 13 .6 million square feet of pavement. The estimated replacement value of this pavement is approximately $23 .7 million for arterial streets , $56 million for collector streets , $26 .3 million for residential streets , and $2 .7 million for alleys , for a total of $108.7 million . Preservation Program and Costs : The PMP Report recommends a strategy based on a six-year maintenance cycle. The objective is to reduce the back log of street preservation work over the next six years and to maintain or increase the overall condition of the street network . Th is strategy involves two trad itional pavement rehabi litation treatments including slurry seal and asphalt overlays as preservation components . The strategy also uses a three percent annual inflation factor for all maintenance costs, wh ich has been incorporated into the numbers used in th is staff report. The following scenarios were presented in the report for "Unlim ited Funding" and for "Ma i ntain Current Condition ." Unlimited Funding : If the entire street system were to be rehabilitated at once , the initial cost would be $24 ,093,454 , wh ic h would bring the average Citywide PCI to 92 . The combined annual maintenance costs for the following six years would be $5,467 ,291 , for a total cost of $29 ,560,475 . Under this scenario, the average Citywide PCI would be 83 at the end of the six-year program. Maintain Current Condition : In order to maintain the Citywide average PCI at or above the current PCI of 62 over the next six years , the PMP Report states that approx imately $3 million per year would need to be budgeted for ongoing ma intenance . Progress to Date and Lev eraged Funding : The PMP Report is used as the basis for making strategic decisions to effectively and cost efficiently plan future work . The City Engineer conducts field observations to update and supplement the information in the PMP Report. Cost effective street rehabilitation projects City Council October 20 , 2015 Page 3 of 3 are then planned with efficient cost/benefit ratios based on field conditions, other relevant projects , budget availability , and various other factors that may exist at the time . For example , in conjunction with the Safe Routes to School (SR2S) project and the ongoing Bicycle Transportation Account (BTA) project , the City Engineer observed actual pavement conditions in areas where SR2S and BTA improvements were programmed to occur, using the PMP Report as the basis for the observations . Based on the City Engineer's findings , PMP funds were used to leverage the SR2S and BTA grant funding to rehab ilitate streets where other grant-funded work was already occurring . Since 2013 , the SR2S and BTA projects , along with the Rosemead Boulevard beautification project, have rehabilitated approxi mately 2 million square feet of pavement, representing about 15 percent of the City's total 13 .6 million square feet of pavement surface area . CONCLUSION: Staff continues looking for cost effective approaches and funding opportunities to implement the City's PMP . As funds become available , projects will be planned and grouped together to the extent feasible to maxim ize the cost/benefit ratio . FISCAL IMPACT: To date, $1,485 ,000 has been allocated for the PMP using gas tax funds . This funding was allocated in the Fiscal Year (FY) 2014-15 budget and utilized in conjunction with the SR2S project. Remaining funds from FY 2014-15 were reallocated for FY 2015-16 and are currently being utilized in conjunction with the BTA project. At this time no additional funds have been allocated for PMP implementation . Staff will continue to identify potential funding sources and opportunities to leverage funding where possible .
