Mr. A. C. Gonzalez January 26, 1984 City of San Marcos Page 3 The 1983 and 1987 elevated storage requirements are 1.43 MG and 1.54 MG, respectively. An addition of 1.75 MG is proposed to supplement the existing capacity of 1.35 MG. Therefore, the additional requirements are 0.08 MG for 1983 plus 0.11 MG for 1987, leaving 1.56 MG as surplus storage. On this basis the elevated storage improvements cost has been assigned as follows: 5 percent each to existing development and new growth through 1987, and 90 percent to new development after 1987. The low percentage requirements shown for development through 1987 should not be misconstrued as a minimization of the need for these improvements. Elevated storage in the areas planned is definitely needed now. The sizing of the tank was based on future needs and the desire to maintain the 80/20 percent ratio between ground and elevated storage. It is typically not economical to size elevated tanks for design periods less than that used in the report. The total cost for facility improvements is estimated at $3,457,300. In summary, it is estimated that capital improvements to the water distribution system required through 1987 will cost approximately $9,951,800. It is recommended that $2,467,050 of this cost be borne by the existing development served by the system. Of the remaining amount $1,036,250 should be paid by new development added to the system through 1987, with $6,448,500 assigned to development beyond 1987. Using the population projections cited earlier and a factor of 3.5 persons per connection (based on single-family living units), a cost of $1,245 per connection is estimated for growth through 1987. Beyond the year 1987, it is difficult to estimate the cost per connection since additional pipelines and facilities will be required at that time. However, without these additional improvements, the cost per connection to development after 1987 is estimated to be $1,245. The estimated costs used in this ~eport were taken from those presented in the "San t'iJarcos Water System Study" performed by Freese and Nichol s, Inc., in February, 1983. The costs have been adjusted for inflation to represent mid-1984 costs. For work done after that time, a 6% increase per year is suggested to allow for future inflation. Prior to 1987, the capital recovery fee should be reviewed, with consideration given to the amount and nature of ongoing development, as well as additional improvements which may be indicated at that time.
