HEAD SUBJECT: Pavement Management Program 0 9F Review report and consider whether the proposed FY 97 -99 budgets for the Pavement Management Program expenditures should be adjusted to the full recommended program level. Report Summary: This report examines the impact of reducing Pavement Management Program expenditures from the full recommended program amount, to a target amount of approximately $600,000 per year. The report attempts to quantify the additional cost to the City in terms of additional system depreciation which will result, and identifies the particular streets throughout the City which will not receive some from of preventive maintenance treatment over the next six year cycle of the program. To begin with, expenditures for the full recommended program for the next six year cycle average approximately $759,000 per year, or $4,553,661 total. According to the computer program, actual expenditures for the $600,000 average annual target program are calculated to be approximately $593,000 per year, or $3,557,877 total. Thus, the difference in spending between the full recommended and target programs for the next six year cycle is approximately $166,000 per year, or $995,784. Under the full recommended program scenario, after six years, the City's street system will have depreciated by 4,800,185 square - yard- years, or by an additional 1.9 years. (In pavement management lingo, square- yard -years is the hypothetical unit by which one measures pavement life. For a more thorough explanation of the concept, please refer to the attached summary description of the Pavement Management Program.) Similarly, under the reduced funding alternative, after the same period of time, the City's street system will have depreciated by 7,048,787 square -yard- years, or by an additional 2.8 years. Thus, the difference in total system depreciation between the full recommended and reduced programs amounts to 2,248,602 square - yard- years, or .9 years worth of system depreciation. Looking at this from a dollars and cents perspective, the total cost to the City associated with each program is calculated as the sum of 1) the cost associated with system depreciation, and 2) the expenditures on pavement management contract work. For the reduced program, system depreciation costs are estimated to be $5,857,577. Adding to this amount the $3,557,877 expense on pavement management contract work, one arrives at a total cost associated with the reduced program of $9,415,454. Or, in other words, under the reduced program alternative, the system will depreciate in value by $1.65 for every $1.00 invested in preventive maintenance. For the full recommended program, system depreciation costs are estimated to be $3,974,785. Adding the $4,553,661 in contract work results in a total cost associated with the full recommended program of $8,528,445. Under this scenario, the system will depreciate in value by 87� for every $1.00 invested in preventive maintenance. Computing the difference between the two alternative programs reveals that overall system depreciation will be reduced by $1.89 for each additional dollar invested in preventive street maintenance. The ultimate goal of the Pavement Management Program is to achieve a steady state whereby the amount of system depreciation each year is offset by the amount of restored system life associated with annual investments in preventive maintenance. Our best guess is that once a steady state is achieved, annual expenditures on preventive maintenance will need to continue at somewhere between $250,000 and $450,000 to maintain the steady state. The reason the City must spend more now on the full recommended program to achieve a steady state is to overcome the amount of system depreciation which accumulated in those years prior to implementation of the Pavement Management Program. If the City were to continue investing in the full recommended program, staff believes that a steady state could be achieved sometime within the next ten years. Spending at the reduced program rate would probably lengthen the amount of time to achieve a steady state to between 20 and 25 years. The attached graph charts system depreciation in years for five funding scenarios over the next six year cycle of the program. Steady state is achieved when the slope of the line for a particular funding scenario becomes horizontal. As one can see, the bottom line, which represents the full recommended program scenario, is the closest to becoming horizontal and is trending flatter. The next line above the bottom line represents the reduced program scenario discussed above. It is not trending flatter at the end of the six year cycle. Also attached are 14 sheets which identify those streets which will not receive some form of preventive maintenance work during the next six year cycle of the program under the reduced program alternative. An IIXII in the left hand margin indicates those streets which will be deleted from the full recommended program if the reduced program is chosen. However, these tables do not identify all of the streets on which work will'be performed under both program scenarios. Attachments: 1. System Depreciation Graph. 2. Tables of streets. 3.

There are approximately 142.3 centerline miles in the City of Saratoga Street System. As shown on the folloVing chart, the current re lacement value of oVr a ency's pavement s $tem is 41.$ Million. Until re entl , a a $y$tgm tic g prbach tQ mana in the m4intena�ce of these necess�r facillities has d en both difficu1 a d expensive to implement. The Qrowin power of the microcom uter,ha$ ]Prought such management well within th budgetary reach of mos Jurisdictions. WHY A SYSTEM IS NEEDED ---------------- - - - - -- Pavement maintenance typically falls under one of three operating philosophies: 1. ua�or rgconst-ruction approximately every twenty years at the end of it s design life. 2. Resurface With an as halt concrete overlay every ten years. The ppavement life could robabl be extended to 50 years but the build -uR of perha s x inc es of material would adveVsely affect drai�ag patterns End surface grades. Major reconstruction wquld be re u�r�d. This approach is th most common one for agencies not ut�lizing a pavement management system approach. 3. Deyelopp a com Vehensive preventative maintenance program. B utilizin aRpro riate alternative surface treatments the s stem mor than do ble the time between required overl4ys. TAus, th probable 11fe of, a street before it needs reconstruction because of surface distortions is doubled to approximately 100 years. T o understand wh the third mana ement policy_ is preferred, We must look at the mec anism by whic$ 4Lvements fai and how a variety of surface treatments provide ehabilita ion and added Zife. - 1 - PAVEMENT FAILURE ---------- - - - - -- A new, pVo er11 constructed pavement has an ex ected design life of a proximMl� H. years if no majntenance other Ehan pothole repairs and crack sealing is, Failur of a avement can be measured in terms of ride ualit which,is eneralIXY acc table durin the first 75% of the life cygle, b Eerformed, f,deteriora�tes rappii�ly duki.ng the lash 2�% of the c ple. Poo ride uali'ty gis caused fro Co holes, alli ator cracking, base f i.lure an loss o fine a l �he pavement s rface. Byv a pl inQ appropriate reventatiye, maintenance, activities at critical bit uring the life cicle, significant gains in pavement life can be chieved. It is important to note that a pavement mans ement sv *tem will not prevent the inevitable need for avement reco�structi8n. It Will, however, greatly extend the time until reconstruction is needed. The surface treatments considered in the preparation of this study include: o asphalt concrete overlay • slurry seal • fog /oil seal .o fabric interlayer AO"ft • crack sealing • dig -out repairs These treatments, when pperformed between successive overlayys extend the overall pavement lif w1thout si nlficantiv increasing the thickness of the pavement itself. Additional bendfits incMde: ■ pavement is sealed to revent penetration of damaging later into the base rock and subgrade • re uvenate the as halts,in the existing surface that ha�ebecome hard nd bV ttle because of exposure to sunlight and other environmental factors • �royide improved wearing surface and therefore increased ehicle sa ety - 2 - Because reconstruction eatments range from can less cost than o er 21 per .42 s vd. J s uaVe ard, and surface �re uv�ia in� Gent) to Xd. a.c. overlaay), hllAy"�sg6n possiblee s� see th t it is es1 able to truc ion as long as COST - EFFECTIVENESS OF A PAVEMENT MANAGEMENT SYSTEM -------------------------------------------- - - - - -- The "bottgm, line" is that a properl implemented pavement management s stem, utilizing a variety f sutfacx treatments, will cyst less in tie l�nq run than Re "reconstruct" or "overlay onl " alternatives. It can e seed from the follQwin chants that the annul unit cyst of a,pavemegt mapac�ement pro ram is a pproximatelyY 40� of the cost of doing othihhg until failare and 509 of the, b$t,of over14 Ing every 10 years. It. can 1pe easil seen that there are significant savirihgs from a p eventative maintenance program. THE RESTORED -LIFE CONCEPT ------------------- - - - - -- In order to quantify the total life lost from a pavement system each ear, and the amount of life ut rack into the s stem b preventative maintenance treatments, thR PMi system uses th conce�t of pavement life measured in "s uare yard -years . We, assume that a sguarc ard of Aavement loses one �S uare ard -year of life a ch year if n6 maintenance is erfo -med. When 2 surface treatment is applied, from one to, twent Year of life are returned to each square yard. The expected life incrpasx ls, a function of the type of treatment, age, of the pavement revious maintenance, efforts, the qualit of the. 'original cpnstruction, Ednd the classification of the street (type and amount 8f traffic). The life extens ion resulting from each treatment for several street classifications is shown on the following avement Maintenance Life Extension ChaVt. For example, a slurry seal Applied to an arterial should extend its life from 3 to _5 years. Since the chart also includes the current cost er square ard for each treatment, we know the cost per square yard per year of apMing each type of treatment. The advantage of, the s uare yard-year approach is that life added to gavement from various tr�atmentxs can be added together to determine the umulative effect of a comprehensive rogram. The long ran a goal of the pavement management system is to add bRck as many square yard -years to the system as aVe lost e1c he must be added to reduc the ba k year. Until such a stead -state o 1 is achieved hbVever additional ll og of deferred maintenance. - 3 - The rQsulting work rogg am for each year is the mixture of treatments that wall most economycai extend the life of the total vement s stem.

RESPONSIBILITIES OF THE AGENCY ------------------------ - - - - -- In o der for a avement anagement system to be successful in cost effec iyelx extending the ife of a street system, the following factors must exist. o Budget managers must su ort the concept of avement management and made rgason�ble efforts �g make adeqquatb, funds available annuallyy This will revent the necessit of eX endin lar er amounts ig futuYe �ears to to ally Veconstruct filed avemets �ecause of failure to erform preventative maintenance. o Staff must understand the technical and administrative as ects of the pavement management system, and must keep the program data up to date. The pavement management system provides the necessar dogumentatjo� to allow ppublic agency offiglals to make educated, res onsible decisions regardih the qse of limited pavement maintenance d llars. In light of thg proven nature of the PMi Pavement Management System cpnceppts used, offic }aps can defend their decisions and ea$ily explain to, their con$tituents the need for cost -ef ective expenditures. PMi provides an easily understood, lon range too for the management of one of the agency's largest infrastructure investments. - 4 - REPLACEMENT CVALUE fOFaTHEoSTREET SYSTEM - - - -- REPLACEMENT - - - - -- DESCRIPTION DATA COST VALUE ------------------------------- - - - - -- - - - - -- - - - - -- --------------- - ASPHALT PAVEMENTS MAJOR ARTERIAL TOTAL SQYARDS 205,444 $21.50 $ 4,417,046 MAJOR ARTERIAL TOTAL LENGTHS Ift) 52 334 MAJOR ARTERIAL TRAVEL LANE MILES 1 ;.76 ARTERIAL TOTAL SQYARDS 155,305 $20.00 $ 3,106,100 ARTERIAL TOTAL LENGTHS Ift) 44 476 ARTERIAL TRAVEL LANE MILES 1'1.61 COLLECTOR TOTAL SWARDS 326,044 $19.50 $ 6,357,858 COLLECTOR TOTAL LENGTHS Ift) 99 786 COLLECTOR TRAVEL LANE MILES 3'1.25 LOCAL TOTAL S?NARDS 131,299 $17.50 $ 2,297,732 LOCAL TOTAL LENGTHS Lft) 42 740 LOCAL TRAVEL LANE MI ES 1.18 HEAVY INDUSTRIAL TOTAL SQYARDS 0 $19.00 $ 0 HEAVY INDUSTRIAL TOTAL LENGTHS Ift) 0 HEAVY INDUSTRIAL TRAVEL MILES .00 gLANE LIGHT INDUSTRIAL TOTAL LENGTHS 0 $17.50 $ 0 jft) LIGHT INDUSTRIAL TRAVEL LANE MILLES .00 RESIDENTIAL TOTAL SFYARDS 1,120,006 $16.00 $ 17,920,096 RESIDENTIAL TOTAL L NGTHS (ft) 316 268 ;.94 RESIDENTIAL TRAVEL LANE MILES 11 CUL -DE -SACS TOTAL SQYARDS 573,396 $13.50 $ 7,740,846 CUL -DE -SACS TOTAL LENGTHS Ift) 195 771 CUL -DE -SACS TRAVEL LANE MILES 71.14 ASPHALT PAVEMENT TOTAL LENGTHS (ft) 2,751,375 $ 41,839,678 ASPHALT PAVEMENT TRAVEL LANE MILES 284.88 PORTLAND CEMENT TOTAL SQYARDS 0 $35.00 $ 0 PORTLAND CEMENT TOTAL LENGTHS �ft) 0 PORTLAND CEMENT TRAVEL LANE MI ES .00 GRAVEL AREAS TOTAL LENGTHS Ift) 0 $ •00 $ 0 GRAVEL AREAS TRAVEL LANE MILES .00 DIRT AREAS TOTAL SgYARDS 0 $ .00 $ 0 DIRT AREAS TOTAL LENGTHS �ft) 0 DIRT AREAS TRAVEL LANE MI ES .00 ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- CENTERLINE MILES TRAVEL LANE MILES TOTAL SQ.
