in effect4309.05 - Traffic Impact Study.

(2) The expansion of an existing Development; or
(3) All Developments requesting:

(b) Zoning Variance;
(c) Special Permit; or
(d) Preliminary subdivision plat approval.
(B) A Traffic Impact Study may be required for Developments if the Memorandum of Understanding demonstrates the traffic generated will add 100 or more non-pass-by trip ends at the peak hour of the land use at a single, adjacent intersection or based on other factors contained in the current version of the Multimodal Transportation Impact Analysis for Site Development recommended practice report of the Institute of Transportation Engineers.

(1) Land use change;
(2) Access location change;
(3) Significant land use change close to the site; or
(4) Any other significant change to the site.
(D) Traffic Impact Studies shall maintain a Satisfactory Level of Service and safety.

(F) The Director may waive requirements imposed upon the developer to prepare a Traffic Impact Study when the preparation of a study would create unnecessary or duplicate analysis when considering the following factors, including but not limited to:
(1) Existing roadway infrastructure;
(2) Planned capital improvement projects;
(3) Proximity of buildings to right-of-way at potential study intersections that may render additional right-of-way dedication and modification of lane configurations at such potential study intersections infeasible; and
(4) Previous studies in the vicinity of the site (either privately or publicly funded).
(G) Detailed requirements for Traffic Impact Studies are found in the Development Traffic Studies Rules and Regulations developed pursuant to Section 4309.04 of this Chapter.
