Is there flooding of basements and what, if so, is being done to eliminate the situation? The existing City sewer located in 12th Avenue (14th in County) that serves the referenced area, discharges to a combined trunk sewer in Freya Street which flows to the large combined trunk sewer in Hartson Avenue . These trunk sewers have plenty of dry-weather capacity but have surcharged under certain wet-weather conditions. The addition of the four homes would have minimal effect on the overall capacity of this system. The City has a construction project scheduled for 1994 that will provide additonal wet-weather capacity to this system to mitigate the surcharge problem. 3) What is the ability of the existing water system to adequately handle capacity and pressure to these new homes and future development? A 12-inch main in 14th (County) and a 6-inch intertie in 13th (City) from approximately 350 feet east of Cuba to Havana are being constructed by the developer to serve the four new homes with adequate capacity and pressure. Future development in this area will require additional looping of the water system consistent with location of development. Ultimately, a new 12-inch main will have to be constructed from Freya Street to this area to handle major development in this area. 4) Is there enough water pressure to serve these homes and to provide adequate flows for fire protection? With the improvements constructed as discussed under question 3, there will be adequate capacity and pressure to these homes for domestic use and fire protection.

Scott 5) If there is a problem with the existing utilities in the area, should the county restrict future building permits for the area? For the project that has been proposed, we feel that improvements are being constructed that provide adequate sewer and water service to the area. Each development that is proposed will be analyzed to insure that adequate utility service is available. Should there be a problem with a particular development, it would be our intent to communicate this problem early in the process so that building permits could be restricted until such time as the problem could be corrected. If you have any questions or any further information is required, please contact Eldon Brown of the City Public Works Department at 625-6300. Sincerely, Irving B.
