2 Utility Asset Summary ~-~~ for San Juan Capistrano ',.1 ~ Appendix A contains a map for each potential replacement project based on this break data. These project extents will change after the City conducts a more detailed assessment and incorporates break data collected after The project extents shown are only meant to provide a basis to determine planning level replacement needs. The 15 miles identified constitutes approximately 7% of the system that should be replaced as of Additionally, based on the system characteristics and the performance of similar utilities, it is estimated that an additional 0.25% to 0.5% of the system will need to be replaced annually. Assuming the 10 year renewal period ends in 2025, this yields an additional 4% - 8% of the system requiring renewal from the baseline year when data was available (2012). Therefore, we forecast that approximately 11% to 15% of the distribution system, as well as the associated services, meters and appurtenances should be replaced by With respect to reservoirs and pump stations, we assumed that infrastructure older than 35 years would need to be replaced or renewed over the next 10 years. Improvements for the GWRP are not included in these forecasted projections. Based on these assumptions the forecasted capital cost for the water system ranges between $33,000,000 and $56,000,000. Table 3-2 summarizes the range of estimated costs for the linear and vertical potable water assets. Table 3-2. Potable Water 10-Year CIP Forecast POTABLE WATER CIP FORECAST (LOW RANGE) CIP FORECAST (HIGH RANGE) Linear Assets Reservoirs Pump Stations Total $28,000,000 $4,000,000 $1,000,000 $33,000,000 $39,000,000 $9,000,000 $8,000,000 $56,000, Recycled Water System Limited data is available regarding the condition of the recycled water system. The recycled water system is relatively new, has experienced low levels of breaks, and generally has a lower consequence of failure than the Potable Water System. Therefore, the renewal needs of the recycled water system are considered negligible. This 10 year investment forecast assumes 1% of the infrastructure will need to be replaced over the next 10 years, approximately $1,000,000. A high and low range is not provided since they are relatively the same estimate. Table 3-3 summarizes the range of estimated costs for the linear and vertical recycled water assets.

3 Utility Asset Summary 1-)"" for San Juan Capistrano ~ 3.4 Wastewater System In the City's 2004 Sanitary Sewer System Master Plan, the City inspected 58,000 linear feet of gravity sewer pipe and 140 manholes. Approximately 9,800 linear feet (about 17% of pipes inspected) were identified for renewal. Twenty three manholes (about16% of all manholes inspected) were identified for minor renewal work ranging from installing new rungs, raising manholes, and applying epoxy coatings. We evaluated the decision making criteria used by City staff to develop capital projects; we determined that the City is relatively risk adverse and focuses on extending the useful life of pipes using trenchless technologies before the pipe deteriorates to a state where more costly renewal techniques (i.e. excavation) is required. Based on the City's Sanitary Sewer Management Plan, updated in August 2014, the entire system has been inspected and is re-inspected and re-evaluated for structural deficiencies once every four years. Now that the City has applied this approach to its entire system, it is assumed that acute structural defects will rarely be discovered. The 1 0-year wastewater capital forecast will provide a range of investment levels depending upon various risk management and infrastructure condition assumptions. The high end of the range assumes that the risk tolerance and current condition of the system is similar to that found in the 2004 Sanitary Sewer System Master Plan. It also assumes that minor levels of deterioration that typically occur in collection systems is counter balanced by the City's four year inspection and renewal program and the renewal that has already been conducted as part of the 2004 Sanitary Sewer System Master Plan. Therefore, about 17% of all pipes will require renewal and about 16% of all manholes will require minor renewal over the 10 year investment forecast. In general, the 2004 Sanitary Sewer System Master Plan decision criteria is relatively risk adverse when compared to the rest of the industry. Additionally, the areas that were inspected were believed to be areas of the system in the worst condition based on age, material, and infiltration rates. Therefore, the low end of the 10 year investment forecast assumes that yield rates will be approximately 5% lower based on increased risk tolerances and the remaining portion of the system being in better condition. Therefore, we forecast that about 12% of all pipes will require renewal and about 11% of all manholes will require minor renewal over a 10 year investment. Based on these assumptions the forecasted capital cost for the wastewater system ranges between $9,000,000 and $14,000,000. Table 3-4 summarizes the range of estimated costs for the linear and vertical wastewater assets. Table 3-4.

4 Utility Asset Summary 1-'~ for San Juan Capistrano J ~ 3.5 Gravity Stormwater System Limited data is available regarding the condition of the stormwater system. In general, stormwater pipes are exposed to similar deterioration mechanisms as gravity sewer pipe and in the City's wastewater system, are of similar age. In general, the City's stormwater pipes have a lower consequence of failure but far less condition assessment and renewal has historically been conducted relative to the sewer system. For the purposes of this 10 year investment forecast, it is assumed that the renewal rate in the stormwater system will be similar to that of the wastewater system. Forecasting a range of 12% renewal to 17% renewal for the stormwater system, the CIP forecasted cost will range between $11,000,000 and $16,000, Summary of Forecasted Capital Improvements Based on our review of the asset registry and available condition data, we developed forecasted costs of improvements that a utility operator may consider in developing a valuation of each utility. We present a range of costs because these values represent possible capital improvements which must be reviewed and evaluated prior to commencing any project. Table 3-5.
