As such, the <br />revenue requirements are made up of two types of costs, 1) direct stormwater program, <br />costs and 2) adjustments for the following: <br />~ - <br />• revenue lag <br />• reductions ~~~ <br />• operating interest income. <br />I <br />'i billing wiite-offs. - <br />Whenever there is a rate increase, the revenue lag affects collected revenues at the <br />beginning and end of the fiscal. year. -For example, the City will receive revenue that was <br />generated at ,the end of FY1993-94 in the beginning,of FY1994-95. Similarly, the <br />revenue generated at the end of FY1994-95 will be received by the City in FY1995-96. <br />~, <br />I . <br />j Thus, in any one fiscal year; the City will receive revenue that was generated with the. <br />rates of the previous year and will not- collect all of the revenue that was generated with <br />~~ the rates of the current fiscal year. All else being equal, an increase in rates from one- <br />. year to the next would mean that the cash received during the first year the rates are <br />- <br />increased would be less than the revenue requirements :for the. year. The rate model <br />adjusts for the revenue lag by increasing the revenue requirements so that the City will <br />collect all of the revenues that it needs to cover program costs. <br />~; Accounting for reductions -e~~~ptiens (see section 6.0) is another adjustment that <br />~, the rate model makes to assure the revenue requirements are met.
