A. Sewer Lift Station Master Plan – West Point City. The western portion of West Point City is not serviceable by gravity sewer lines to the main fallout sewer line which runs in 4600 West to the North Davis sewer treatment plant. A series of sewer lift stations is currently serving the residents that are lower than the sewer fallout line. Concern has arisen as residential development is proposed as to the area that the existing sewer lift stations can serve and the life expectancy of these lift stations. Due to topography the existing lift stations cannot serve much of the property that is west of 4500 West.

West Point City has developed a sewer lift station master plan for the western portion for the city requiring sewer lift stations. The master plan designates four sewer lift service areas; these are shown in Appendix 1.¹ Table 1 contains the land areas for each service area and the number of estimated future homes.

The buildout capacity shown in Table 1 is based on a buildout of 50 percent. Roads, drainages, parks, wetlands and other nondevelopable areas will be a portion of the remainder. This developable area is not as conservative as that which is used for the infrastructure sizing but is felt to be more accurately reflecting actual buildout of the areas due to some of the sensitive environment.

B. Development of Sewer Lift Stations. To facilitate the construction of the sewer stations for each area, the first developer in the area that does not have the infrastructure that meets the sewer lift station master plan must construct and fund the required infrastructure for that area. The city will then enter into a “pioneering agreement” with the developer to defray some of the developer’s expenses for the construction costs. This agreement will be in effect for a period of 10 years or until the full payment due under the pioneering agreement has been paid, whichever comes first. The development fees will be calculated based on the following:

Development Fee = ((Construction Costs – City’s Contribution)) / (# of Homes Serviceable)

West Point City’s contribution to the construction costs of these lift stations would come from the applicable portion of any sewer impact fees that have been collected on any existing home in the sewer lift service area in question. The applicable portion of the sewer impact fee would be determined from those projects that were used to develop the sewer impact fee and coincide with or are replaced by those projects required to meet the current sewer lift station master plan. The new development fee would need to be passed with a resolution by the city council once the agreement between the city and the developer has been established. The development fee would then be charged in place of the existing impact fee when the building permit is issued for any future home built in this area.

Before the agreement between the city and the developer is made, the service area will be studied in depth to determine the number of serviceable homes that could be built. This should take into account wetlands, drainages, roads, existing development and other factors that could affect buildout densities throughout the area in question.

The infrastructure constructed in each area must be approved by and meet the specifications of West Point City.

The sewer lift station for Area 1 should be developed in two phases as shown in Appendix 1, attached to the ordinance codified in this chapter. The costs associated with developing the infrastructure required to complete the lift station to serve the entire Area 1 are too large for any one developer. Developing Area 1 in phases reduces the amount of initial infrastructure that is required. The land served in Phase 1 will develop before that of Phase 2. The lift station for Phase 1 is located just west of 4500 West on 1300 North to serve the area felt to develop first, and then Phase 2 can be completed as that area is developed. The sewer lift station for Phase 2 would be located at about 5000 West and 1300 North. Buildout of Area 1 will probably occur over the next 30 years.

In Areas 2 through 4, it is believed buildout would occur quickly once the infrastructure has been constructed due to small size of the area that is being served and the size of the development required to justify the sewer lift station infrastructure. [Code 2000 § 18-5-1].
