Traffic Impact Analysis Form

Sumter County Traffic Impact Analysis (TIA)

  1. Sumter County Traffic Impact Analysis (TIA)

    In accordance with the Interlocal Service Boundary and Joint Planning Agreement between the City of Bushnell, City of Center Hill, City of Coleman, City of Webster, and the City of Wildwood,  within the municipal service area, the Cities and County agree that County will review all traffic impact studies for development accessing the City or County road networks.

  2. Purpose and Applicability

    The purpose of the TIA is to identify the potential traffic impacts of new development on the transportation system and to develop mitigation strategies to offset those impacts according to the methodologies and provisions as described herein. These guidelines apply to all new development within Sumter County, including its municipalities, submitting building and site plans for review. The TIA requirement applies to previously approved developments that are over five years old, changing land uses within the site plan, or extending the build-out date from a previously approved TIA. Unless otherwise required by the County Administrator or designee, a TIA, as it relates to a substandard roadway section, shall not be required for any single development generating less than 50 average daily trips, as per the Trip Generation Manual, latest edition, as published by the Institute of Transportation Engineers (ITE). The following thresholds will determine the level of study that will need to be performed depending on the number of trips a development produces:

    1. Applicants proposing developments that generate 50 but less than or equal to 1,000 average daily trips (ADT), according to the ITE Trip Generation Manual, current edition, must perform a Minor TIA.
    2. A Major TIA shall be required for all proposed developments generating more than 1,000 ADT, as per the ITE Trip Generation Manual, current edition.. 

    For purposes of this section, a "single development" shall include any development, parcel of land, lot, and tract, and contiguous or nearby developments, parcels, lots, or tracts that are:

    1. Developed by the same or a related development or landowner;
    2. Developed as part of the same zoning plan, preliminary plan, preliminary site plan, plat, or other unified or common plan of development. 

    These guidelines are in addition to the requirements of the access management regulations. In the event of any conflict between these guidelines and such regulations, the more stringent requirements shall apply.

  3. Methodology Statement

    Before conducting a Major TIA, a methodology statement shall be prepared by the applicant, the applicant's representative, or the applicant's engineer/consultant and submitted for review and approval by the County. Before conducting a Minor TIA, the applicant, the applicant's representative, or the applicant's engineer/consultant shall seek confirmation from County staff on the need for a methodology statement. The purpose of the methodology statement is to establish agreed-upon methodologies and assumptions before the start of the TIA. A methodology statement shall be prepared using the guidelines provided in the following paragraphs. The methodology statement will be first reviewed by County staff, if necessary, through a methodology meeting with the applicant and or the applicant's consultant. The applicant's consultant will then revise the statement based upon agreed-upon methodologies. The applicant shall ensure the consultant does not prepare a TIA without a methodology statement approved by the appropriate County representative.

  4. Applicants can submit an exemption due to a development generating less than 50 average daily trips, as per the Trip Generation Manual, latest edition, as published by the Institute of Transportation Engineers (ITE).
