Requirements.
Tupelo Development Code § 12.5.5
in effect12.5.5. - Requirements.
(1) Content: The Development Services Director or designee shall set forth specific guidelines for preparation of TIAs. A TIA shall, at a minimum, provide the following information:
(a) An estimate of the traffic generated as a result of the proposed development;
(b) An analysis of the existing street system serving the proposed development; and
(c) An assessment of the improvements needed to the existing street system in order to support the traffic anticipated to be generated by the proposed development.
(2) Preparer: A TIA shall be prepared by a registered professional engineer with experience in traffic engineering.
(3) Sources of Data: Estimates of vehicle trips shall be calculated based on trip generation rates from the most recent edition of the Trip Generation Manual published by the Institute of Transportation Engineers, unless an alternative source of information is approved by the Development Services Director or MDOT.
(4) Period of Validity: A TIA shall be valid for a specific site for no more than eight years, so long as no significant modifications to the development proposed for the site that substantially increase the traffic impact are made. A TIA submitted in connection with a project that is accessed by a road that is operating at a level of service lower than that approved by the City Engineer or MDOT, if applicable, shall be valid for no more than five years, however.
(5) Coordination with Zoning Map Changes, Site Plans, and Preliminary Plats: Transportation mitigation measures may be required to address issues raised by a TIA, or as part of the approval of a Transportation Special Use Permit (TSUP). Such measures may include, but shall not be limited to, onsite and offsite improvements related to reduction of traffic impact on the surrounding road system, bicycle facilities, pedestrian movement, and the environment. These measures shall be conditions of development approval. Deletion or modification of these conditions shall require the same approval process that was required for the original project, unless the approved mitigation measure is deemed to conflict with MDOT or City of Tupelo requirements, in which case they may be deleted or modified by the Planning Committee.
