Phase 5 Annexation - Annexed Fall 2005

OVERVIEW
This information represents an analysis of estimated costs and a proposed sequence of installation of PWC sanitary sewer facilities to serve residential developments located within practical reach of existing PWC sewer trunk mains and collection lines.

To determine the projected cost for extending sewer into these developing (or fully- developed) residential properties, a comparison of these areas was performed using a similar developed area within the City as a baseline. For the purposes of this study, three subdivisions - Loch Lomond, Devonwood and Murray Fork were combined into one control database.

Projected costs for extending sewer into the proposed areas are based upon the number of developed parcels without sewer having a structure value greater than $10,000, the total linear feet of new sewer required, and the ancillary costs for approach mains, pavement patching, etc.

Ranking of the proposed areas in order of sewer installation is based upon the following factors: Septic system repairs/ failures, age of structures, percentage of non- sewered improved lots, the availability of existing approach mains, and lot density. Some areas with lower ranking must be installed ahead of areas of higher rank in order to provide access to larger collection mains.
