A Traffic Impact Analysis (TIA) provides information on the projected traffic expected from a proposed development. A TIA also evaluates the impact of proposed development on the roadways in the immediate proximity of the proposed development. The TIA should identify any potential traffic operational problems or concerns and recommend appropriate actions to address such problems or concerns.
A traffic impact analysis shall be consistent with the code requirements and the Transportation Criteria Manual. The geographic area to be considered in the TIA shall be established by the Director. The TIA should consider and account for the potential traffic to be generated by other undeveloped sites within the established study boundaries.
A neighborhood traffic analysis is a simplified TIA that assesses the impact of a proposed project on residential streets. A neighborhood TIA is limited to an evaluation of existing and projected operating levels of residential streets and an identification of mitigation measures needed to minimize traffic impacts.
TIA requirements apply to each individual lot when an application is made to zone or rezone the lot or for site plan approval to develop the lot.
Generally modifications to an application may include but are not limited to:
Vehicle Trip Thresholds A local or collector street means any roadway not designated as an arterial street. A residential local or collector street is one along which 50% or more of the frontage within 1,500 feet of the proposed project's property lines (or the nearest arterial, whichever distance is less) is zoned SF-5 or more restrictive uses.
