For this preliminary study, the calculations from Roseville were used as an estimate dUe to the city's proximity. These figures are given in the following table. Residential Standard 2" Equivalence Land Use Rain Runoff Factor Residential 0.24 1 Multiple Family 0.56 2.5 Commercial 1.24 5 Industrial , 1.24 5 Schools 0.30 1.25 churches/Govt. Bldg. 0.56 2.5 Parks 0.18 0.75 Cemeteries, Golf courses 0.09 0.25 ,- . The residential equivalence factor (REF) is defined as the ratio of the average volume of run-off generated by one acre of a given land use zone to the average run-off generated by one acre of typical single .familr residential land, during a standard one year rainfall event. The REF values in the preceding table were then rounded to the nearest 0.25. 2. Determine the cost of needs which will be funded by this utility. An estimated amount required to finance the uses of the utility was computed. This was done by determining the quantity of undersized pipes in the system identified in 1984 Barr report and then estimating a replacement cost. See Appendix C for a detailed table of the estimation of undersized pipes. In the following table there is a breakdown of the funds required to finance the cost of the needs described on page 4. Currently, most of these needs are being funded by property taxes and/or assessments. Maintaining a storm water master plan and some of the reconstruction costs are presently not funded. These are new needs which the storm water utility fund could pay for. . No.937, city of Roseville -----
