Transportation Engineers' Trip generation Manual, (current edition). In the event that suitable data are not available for the proposed land uses(.$), the Public Works Director must approve estimates prior to acceptance of traffic impact analysis results. d 4. Level of Service Standards. No proposed development shall be approved which reduces the Level of Service .(L.O.S.) on major thoroughfares and/or major intersections below L.O.S. "C" on an average annual basis, or below L.O.S. "D" during OtflM$ peak hour/g5t peak season conditions. Level of Service standards shall be based on definitions established within the "Highway Capacity Manual", (current edition), by the Highway Research Board. Where unsignalized major intersections exist within the boundaries of the traffic impact analysis study area, such intersections shall be analyzed to determine if the warrants for signalization contained within the Manual of Uniform Traffic Control Devices have been satisfied. If si nalization is warranted, signalization, geometric improvements and/ortraffic control restrictions must be provided in order to meet acceptable service levels. An intersection which fails to meet si nalization warrants requires no further level of service analysis. 0 5. Preparation of Traffic Impact Analysis. The analysis shall state all data sources and the methodology utilized in the study. County comments on the analysis will be provided in a written form. fThe applicant will then have the opportunity to incorporate necessary revisions prior to submitting a final report. 6. Contents of Traffic Impact Analysis. a. Study Area Boundaries. The boundaries of the transportation impact areas shall vary based on the peak hour trips gen- erated by the proposed development. The study area shall include all arterial and collector roadways as provided below: Peak Hour Trips Study Area Radius less than 500 1/2 mile 500 to 1,000 l mile over 1,000 3 miles The study area radius shall be measured from the boundaries of the property being developed. Projected impact on barrier island bridges shall be included in the study area report, b.Existing and Proposed Land Uses. The traffic impact analysis shall also include a description of the existing and proposed land uses on the site. The land uses of adjacent properties within a minimum ofq five 'hundred (500) feet, including vacant land, shall also be identified. In addition, the roadways that afford access to the site, and are included in the study area, shall be identified.
