Cost to Extend Water and Sewer Infrastructure into Happy Valley Area After determining how to serve the area, the study then estimated costs to construct the public water and sewer systems required to serve every property within Happy Valley under both scenarios. The details of the cost estimates are contained with the study, but are summarized as follows: Table One Utility Alternative 1: Existing — 92 Parcels Alternative 2: Build -Out — 125 Parcels Water $2.10 Million $2.28 Million Sewer $3.25 Million $3.42 Million Total $5.35 Million $5.70 Million Cost per Parcel $58,000 for water and sewer $46,000 for water and sewer As the table above shows, the cost per parcel under the "Existing" scenario is $58,000 to extend water and sewer into the every existing property within the unincorporated Happy Valley Area. This number assumes the entire water and sewer extensions are built in the near future. As time passes this cost will be subject to inflation. As stated previously there is not a lot difference in the piping systems needed under the two alternatives. This also translates into there not being a lot of difference in the total cost of the systems. The real difference between the alternatives is how many properties would be available to contribute toward the cost of the water and sewer extension. As the table above also shows, if 125 `Build -Out' parcels contribute, the cost per parcel is $46,000. In either case, the cost does not include any improvement to the streets in the unincorporated area, meaning the trench cuts necessary to install the pipe are restored to the existing condition. The costs also assume easements will be provided by the County and area residents to build the systems at no cost to the City. The estimated costs do include a water and sewer stub from the main pipelines to each parcel property line, but do not include the cost of on -site piping required to connect to homes. These on -site piping costs could be significant depending on length of piping needed based upon where a home is built on each property. Total Cost for Each Parcel to Connect to New Water and Sewer Infrastructure As stated earlier in the report, the cost of $58,000 (assuming 92 parcels) or $46,000 (assuming 125 parcels) is not the full cost for each parcel in the area to receive water and sewer. Each property in the unincorporated area would also be subject to the 2002 Council Policy. They would each need to follow a process similar to that previously described for 6723 Alisal Road and would be subject to the same six requirements. Payment of the $58,000 or $46,000 per parcel cost to extend the utilities would be a new seventh requirement for the properties in the unincorporated Happy Valley Area. Table Two on the next page shows the cost associated with each of the seven requirements according to current City, LAFCo, Zone 7, and DSRSD fee schedules. Below Table Two are notes explaining each fee: Page 4 of 7
