County, approval of the final construction plans by the Administrator shall serve as approval of the new connection(s) and no separate permit will be required.
All sidewalk or bikeway connections to the public street system.
Temporary driveways for access to vacant parcels or those on which a building is under construction and that are not served by a permanent driveway. For purposes of permitting, “significant change” is defined as “a chang e in the use of the property, including land, structures or facilities, or an expansion of the size of the structures or facilities causing an increase in the trip generation of the property, based on the Institute of Transportation Engineers "Trip Generation Manual" (latest edition), or other rates accepted by Hillsborough County, exceeding 300 vehicles per day more than the existing use,” (Part 12.01.00 Definitions). If so, the property owner must contact the County to determine if a new permit application and modifications to existing connections will be required. Sites undergoing substantial improvement may also be required to upgrade existing access connections. This is defined as any combination of repair, reconstruction, alteration or improvement of a structure, taking place during a one year period, in which the cumulative cost equals or exceeds 50 percent of the market value of the structure. The market value of the structure should be (1) the appraised value of the structure prior to the start of the initial repair or improvement, or (2) in the case of damage, the value of the structure prior to the damage occurring. This is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. Improvements to comply with existing health, sanitary, or safety code specifications solely to assure safe living conditions are exempted. The County categorizes roadway connections into five types for purposes of design and permitting, using several factors, including expected traffic volume, property type, land use, and connection type, as shown in Table 17. The number of allowable driveways in development and redevelopment proposals is determined by calculating Peak Hour Total Project Traffic divided by Maximum Vehicle Flow, as rounded to the highest whole number.
