GEORGE GREER BARBARA SHEEN TODD June 25, 1985 r:::i~ @J~ 120/11"'7 i'<.'; Ii:' JUN~7 Mr, Anthony Shoemaker, City Manager City of Clearwater Post Office Box 4748 Clearwater, Florida 33518 Dear Mr. Shoemaker: As you are aware by now, the Board of County Commissioners has acted to institute a four-cent Local Option Gas Tax for pinellas County. This action could not have been accomplished without your support and the support of the other cities. Therefore, on behalf of not only the Board of County Commissioners, but residents and highway users, I would like to sincerely thank you for your help. For your information, I am attaching a copy of the documents that were part of the Board's action, These documents include the following: executed Local Option Ordinance; executed Interlocal Agreement with Five Year Funding Distribution and Plan; and anticipated Ten-Year Funding Proposal. I would also like to explain that due to some last minute changes in the legislature, the Board had to, in turn, adjust its program. We had all relied upon the existing law permitting a bonding capability for up to ten years of the entire four-cents. However, this law was rewritten late this legislative session, increasing the Local Option Tax from four cents to six cents. As part of the rewrite, the law was amended to authorize bonding of only the third, fourth, fifth, and sixth cents, When this law did go into effect, it removed the ability to bond the first two cents available to our program, as previously understood. Therefore, to preserve our ability to bond the entire four cents, and have that option for at least a ten-year period, the Board acted on June 18 before the effective date of the new legislation, I must emphasize, it was the Board's intent that by doing this it could then honor the commitment made to bond the entire program and make the money available at the front-end of the program for expenditures. PINELLAS COUNTY IS AN EQUAL OPPORTUNITY EMPLOYER , I I June 25, 1985 Page 2 As you know, our five-year program of transportation projects is very well defined and understood. However, we will need to work with you on developing and finalizing a full ten-year program, I expect this will involve considerable discussion and review before all of the projects are approved. We will keep you informed and involved in these activities as they come forward. Again, I would like to thank you for your support, and we can now look forward to beginning to resolve the transportation problems of Pinellas County. ~ Fred E.

Sources of information may include: Aerial Topograph i c Kaps, Field Survey, Conversat ion with Residents, Record Drawings. 3.1.4 Field Survey A field survey will be carried out to provide the fOllowing: Information required for Sections 3.1.2 and 3.1.3, (sizes, types, locations), Elevations and Condition of all inlets, pipes, culverts and other structures in the drainage systems; Channel cross-sections, Any other information required to complete the Study, 3.1.5 Horizontal control will be referenced to the "Florida State Grid System." Vertical control will be referenced to the "National Ocean Surveys _ NOAA System" (NGVD 1929), 3.1.6 The existing drainage system will be mapped and existing channel cross-sections will be plotted by the Consultant. The existing drainage system is defined as all surface water conveyance, inCluding storm sewer systems, natural channels, and man-made open drainage courses within the study area, 3.2 HYDROLOGIC AND HYDRAULIC CALCULATIONS 3.2.1 The most appropriate computer programs for hydrologic and hydraulic calculations will be selected, based upon the drainage system and basin characteristics determined from data and information collected under Section 3.1,1. 3.2.2 Hydrologic characteristics and drainage system dimensions will be encoded into the appropriate computer model data files. The model will be verified or calibrated by computing runoff rates and water surface profiles resulting from the rainfall recorded during a recent storm event. Kodel parameters will be adjusted to bring the computed water surface elevations into agreement wi th the recorded water surface elevations. 3.2.3 After model cali brati on, runoff rates and water surface elevati ons for "existing" conditions and for "ultimate" development in accordance with the Future Land Use Plan will be computed for 10, 25, and 100-year storm events of 24-hours duration. 3.2,4 Water surface elevations determined per Section 3.2.3 will be plotted and the flood areas will be mapped by the Consultant. 3.3 STORKWATER MANAGEKENT KASTER PLAN 3.3.1 All possible methods of relieving the flood conditions determined in Section 3.2.4 will be considered, inCluding channel improvements, replacement of inadequate pipes and culverts. excavated detenti on areas, di version, preservation of natural storage areas, and restrictions on development, The effecti veness of the improvements considered will be demonstrated by computer modeling. Each of the alternate solutions must bring the drainage system into compliance with Criteria Cl, C2 and C3. Permit requirements for each of the alternates will be considered.
