4.0 Maintenance And Rehabilitation Strategies <br />4.3 BUDGET ALTERNATIVES <br />Having determined the needs of the City local and arterial networks and the City fiscal -year <br />budget for the next seven years, the City utilizes StreetSaver to evaluate impacts of various <br />budget alternatives — existing budget in City CIP, budget to maintain the current PC],, over a <br />seven year plan, and budget to improve the current PCI,, by one point or better over a seven- <br />year plan. StreetSaver has the capability of forecasting the effects of different budget <br />alternatives on PCI and deferred maintenance (backlog). By examining the effects of these <br />indicators, these "what -if' analyses clearly identify the advantages and disadvantages of <br />different funding levels and preventive and major M&R strategies. <br />The following guide is provided for interpreting the individual output in Budget Analysis tables <br />below. <br />• PCI w/o Existing Funding — PCI yielded as a result of no preventive or major M&R <br />work during the listed fiscal year. This value is provided for comparison purposes and is <br />intended to be used as the baseline PCI. <br />• PCI w/ Existing Funding — PCI yielded as a result of preventive and major M&R work <br />with existing funding during the listed fiscal year. <br />• PCI w/ Alternative Funding — PCI yielded as a result of preventive and major M&R <br />work with existing plus additional funding during the listed fiscal year. <br />• Preventive M&R Existing Funding — Existing funding for preventive M&R work during <br />the listed fiscal year. <br />• Major M&R Existing Funding — Existing funding for major M&R work during the listed <br />fiscal year. <br />• Major M&R Additional Funding — Additional funding for major M&R work required to <br />reach the listed goal during the listed fiscal year. <br />• Total Existing Funding — Sum of existing funding during the listed fiscal year. <br />• Total Alternative Funding — Sum of existing funding plus additional funding required to <br />reach the listed goal during the listed fiscal year. <br />• Backlog — Total estimated M&R work left unfunded during the listed fiscal year. <br />City of Santa Ana 2018 Pavement Management Program 4-6 <br />55B-31 <br />
