Fort Walton Beach Council agenda — 05-08-2007 regular agenda — reading text

first Task will focus on understanding the historical if problems<Clnd projects from existing documents and staff, and, staff, meet to review problems and needs with the suggested by Choctawhatchee Basin Alliance and the NWFWMD. It will consist of: II Reviewing existing reports and budgets Interviewing the staff to identify and qualify problem areas Reviewing the City' s NPDES Stormwater Permitting records Reviewing the Choctawhatchee River and Bay SWIM Plan  Engineering/ Consulting Services, Stormwater Utility Study, RFP 01- 113 1 We would recommend one workshop to establish agreement upon the extent of the City' s jurisdiction and the priority of the problems that will be addressed. If customers are to be charged for stormwater, they will have their own expectation as to how those funds should be spent. For example, some residents may expect funds to be used to improve protection for storm surge or improved water quality in Choctawhatchee Bay. The consensus can be, if desired, summarized as the Mission Statement for the Stormwater Utility Program. The workshop could be made up of the Technical Assessment Committee or any combination of staff, elected official, and citizenry as the City may elect. 1. 3 Institutional/Management Assessment Earth Tech wiUconduct an audit of the coordinatiqnots; tor!1water programs and institutionals;tructures among all of the offices;.anddepa.rtments ( Utility, Public Works and .

Task 2, 0 Develop Recommended Utility Program def nsib.lestormwater utility is based on Objective: A fair, equitable, and legally between the fees that are cheirgedeind the services provided establisl1inga nexus There are two legal eVeryone. pays their fair share of the cost ofstormWeiter}. nexuses. that must be established. The first is · referred to the customer how do we compute the bill for each customer. The customer apportionment, or apportionment is often base on the amount of imperviousareei. The second nexus is referred to as the cost apportionment which that are to be paid linkstheseirvices stems from by a customer to the fee itself. By far the mostcQrnmonissue litigated customers challenging that they are not receiving they are being seryicesforwhich the stormwater charged. The public wants to know what they are gQingto getf9r fee, and are they " getting their money' s worth". Together, the two part nexus fee establishes the foundation for the legal requirements for the rate structure, the and the utility' s credit policy. Development of Rate Structure 2. 1. 1 Obtain Assessor' s and GIS Data Earth Tech will work with staff to obtain the correct data from the Okaloosa Assessor and the available City and County GIS databases, which will contain key information for estimating the stormwater utility charge for each parcel.  Engineering/ Consulting Services, Stormwater Utility Study, RFP 07- 113 2. 1. 2 Define Custo.mer Base Earth Tech will characterize the makeup of.. the customers served by the of the StormvvaterProgr9m by conducting a detailed parcel-by-parcel analysis number, size, land- Use, and amount of impervious9reao. e9ch parcel. The data for thisanalysi$ wiUcome primarily from the mapping/ GIS and assessor' s records provided the OkaloOsa County and the City. 2. 1. 3 CUsto.mer ApP.orti. onment Earth Techwillcpnduct a Workshop to present the advantages anq disadvantages for each of the three general rate models, thei;quiva.
