Section 17 AAC 10.075 - Traffic impact mitigation(a) A permittee shall make improvements to a highway or intersection to maintain an acceptable LOS if a highway or intersection has an(1) acceptable LOS under 17 AAC 10.060(b) without traffic generated by the development; and(2) unacceptable LOS under 17 AAC 10.060(b), with traffic generated by the development(A) at the opening date of the development; or(B) in the design year of the development, for a development expected to generate 250 or more vehicle trips during the peak hour of the adjacent highway on the opening date of the development.(b) If a highway has an unacceptable LOS under 17 AAC 10.060(b) without traffic generated by the development, either at the opening date of the development or in the design year of the development, a permittee shall make improvements to the highway so the operation of the highway does not deteriorate more than 10 percent in terms of delay time or other appropriate measures of effectiveness with the addition of the traffic generated by the development at the opening date of the development or in the design year.(c) A permittee for which a traffic impact analysis report has been approved shall use signs and markings on approaches to highways within the development that conform with the Alaska Traffic Manual, 2005, described in 17 AAC 20.950(1), and adopted by reference. Internal circulation and parking layout must provide sufficient queuing distance within the development between the highway and potential internal block points to ensure no traffic backs up onto the highway, including bicycle or pedestrian facilities.(d) If a traffic impact analysis discloses impacts upon pedestrian and bicycle traffic, a permittee shall take steps to mitigate the impact.(e) The department will, in its discretion, relax the requirements for mitigation under this section, if it finds in writing that the (1) highway facilities only marginally achieve an acceptable LOS under 17 AAC 10.070(b) without the traffic generated by the development and would likely fall below an acceptable LOS within five years;(2) traffic generated by the development results in an unacceptable LOS under 17 AAC 10.070(b); and(3) cost of mitigating the impacts is disproportionate to the cost of the development.Eff. 5/4/2000, Register 154; am 2/5/2004, Register 169; am 7/15/2009, Register 191The Alaska Traffic Manual, adopted by reference in 17 AAC 10.075, may be viewed at the department's regional offices in Anchorage, Fairbanks, and Juneau or through the department's Internet website at http://www.dot. state.ak.us/stwddes/ dcstraffic/resources.shtml.
