Discussion of Revisions 13.1 Purpose The existing language provides a clear, concise summary of the purpose of a traffic impact study (TIS). Some of the language, however, suggests that such a study is required only when there are existing capacity or safety problems. 13.2 Conduct This section describes the qualifications for a preparer of a TIS. 13.3 Ant)licability This section describes the types of projects for which a TLS should be prepared. The daily trip threshold is on the low side but reasonable for a rural area. We suggest that a peak -hour threshold also be stated to cover uses that generate a high proportion of their trips during the peak hour. Exceptions should be made for projects that have previously submitted a TIS and which require approvals for minor changes. Conversely, a TIS should be required for building expansion or a change in use that would add at least 800 trips per day or the equivalent peak -hour volume. The provision that some uses may be exempted from the TLS requirement if it is shown that the project will not create a need for traffic improvements is recommended for deletion. In our opinion, the potential need for traffic improvements should be determined by a TIS. Also, specific reference should be made to the Planned Development approval process. Pre- AvDlication ConfergM A new section should be added describing a conference between the planning staff, the applicant, and the preparer of the TIS, at which will be determined the preparer's qualifications, the study area boundaries, planned roadway improvements, links and intersections to be analyzed, traffic distribution, other developments to be considered, available data, peak hours for which analysis is to be performed, and other staff concerns. The study area is of particular interest; a guideline could be the area including all 48
