§ 7.03.01 TRAFFIC STUDY REQUIREMENTS.

   (A)    Proposed development projects are required to provide plans of their development projects to the Site Plan Review Committee, including a traffic study in accordance with § 5.04.01 to determine the impact on the transportation system.

   (B)   Projects determined to be de minimus, are required to provide, at a minimum, the following information:

      (1)   Level of service calculations at each project access point during the p.m. peak hour;

      (2)   A determination of need and length of turn lanes at project driveways consistent with the city’s Land Development Code; and

      (3)   A determination of need for traffic signals or other traffic control devices at project driveways.

   (C)   For projects where a traffic study is required, the traffic study shall be prepared by the developer or his or her designee in accordance with Table 1: Traffic Study Requirements/Guidelines and Table 2: Traffic Study Assumptions and provide the following information:

      (1)   Methodology statement;

      (2)   Study area;

      (3)   Analysis period;

      (4)   Project traffic;

      (5)   Existing conditions;

      (6)   Background conditions;

      (7)   Vested improvements;

      (8)   Capacity analysis; and

      (9)   Transportation mitigation.

   (D)   For projects within the city that front a county/state road, a pre-application meeting with Pasco County is required to determine Pasco County traffic study and review process requirements. Traffic study requirements should be sufficient to address both the city concurrency traffic study requirements and the county/state substandard road and access management requirements.

   (E)   All traffic analysis shall be conducted using generally accepted traffic analysis standards and guidelines.
