Hillsborough Corridor Planning & Preservation Best Practices

Alachua County Alachua County has a multimodal transportation mitigation program to implement its mobility plan. The program offers best practice insight into multimodal corridor planning and mitigation for transportation corridors in Florida. The concurrency program replaced traditional transportation impact fees and proportionate fair share for new projects in the urban service area with a one-time mitigation payment. It is implemented through concurrency, as opposed to mobility fees designed as impact fees, and applies only to developments in the urban service area that lack a valid certificate of level of service compliance. Applicants are required to sign a multimodal mitigation agreement to receive their certificate of LOS compliance. Other developments continue to pay transportation impact fees. As documented by Paul and Nicholas (2011), the mitigation payment is based on the estimated growth in Vehicle Miles of Travel (VMT) as reflected in adopted transportation and land use plans. To derive a per VMT rate, the projected cost of the multi-modal projects identified in the Mobility Plan is divided by the projected increase in VMT between the base year and horizon year of the Mobility Plan. The result is then multiplied by the transportation impact (trip generation, trip length, pass-by, internal capture, etc.) of a particular land use to produce a simple schedule of fees by land use type. Developers could determine their mitigation payment based on land use type or their own alternative analysis. The analysis by Paul and Nicholas (2011) demonstrates that the mitigation payment for a purely roadway- based mitigation program would be significantly higher than a multimodal plan based system. The multimodal transportation mitigation payment applies only to developments other than developments greater than 1,000 dwelling units or 350,000 sq ft of non-residential uses in the County’s designated urban cluster that trigger a level of service deficiency. Large developments greater than 1,000 dwelling units or 350,000 sq ft of non-residential uses must still mitigate impacts through either of the following methods (Policy 1.1.10): (a) Mitigate the proportionate share cost for all significant and adverse impacts to roadways, interstates, intersections and interchanges not addressed through the multi-modal transportation fee. Significant and adverse impacts to roadways, intersections, interstates and interchanges shall include all roadways where the development generates traffic that is five (5) percent or more of the Florida Department of Transportation Generalized Tables capacity at the adopted roadway level of service guideline. Adverse roadways are roadways that operate below that adopted roadway level of service guideline. The Florida Department of Transportation shall be consulted on impacts to Strategic Intermodal System (SIS) facilities, OR (b) Construct and fund multi-modal improvements, to the extent permitted by law, as described below (capital projects shall be consistent with the Capital Improvements Element): (1) Construct one of the following: a. Construct an overpass over Interstate 75 that accommodates at least three of the following modes of travel: walking, biking, driving or riding transit, or b. Construct two (2) miles of an off-site roadway capacity project, or c. Construct four (4) miles of single track or two (2) miles of dual track off-site dedicated transit lanes.
