Quail z Hollow is a residential development located in the m southeast quadrant of the Drake/Overland Trail M intersection. Previous filings of Quail Hollow M accounted for 205 dwe11ino units. This existing development accesse.. Drake Road via 'Yorkshire Street, Pasquinnel Drive, and Overland Trail. Recently, Overland Trail has been paved from Drake to the south 1 imi t of previous filings. It is proposed that Overland Trail paving would continue further to the south to the south property line of the above filings. The City of Fort Collins conducted a traffic_ count on Drake Road just east of Yorkshire Street in September 1=81?. The daily, two-way traffic was 9529. The morning peak hour traffic was 633 and the evening peak hour traffic was 936. These two-way traffic counts were z factored to obtain directional traffic using factors M derived from directional counts on Drake Road near Taft z Hill. W CD Z w The trip generation from the 4th, 5th, 6th, and 7th C F i 1 i nos of Quail Hollow are shov:1n in Table 1. The reference for this analysis is Tr.ik Generation, 4th ' Edition, ITE. The trip distribution used for the vo fol1otAting traffic assignment was 90 percent to the east J a and 10 percent to the west (north along Overland Trail). o It was assumed that there would be little or no traffic 0 N between Quail Hollow and the other residential subdivi- Q sions in the area. • Figure 1 shows the results of the trip assignment 3 at the key intersections along Drake Road. The existing W _ traffic was factored by 3 percent per year to obtain the �-- <a �- IM background traffic. All intersections should be Ccontrolled by stop signs with Drake Road receiving the right-of-way. At the Drake/Overland Trail intersection, the north leg of Overland Trail and the east leg of Drake Road should receive the r• i ght-of-v,iay, as exists today. (4hen Overland Trail is completed to Taft Hi l l Road to the south, the through movement should then be along Overland Trail. Table 2 _.hovels the operation at the key intersec- tions. All intersections v,ii11 operate acceptably. Acceptable operation is level of service D or better during the peak hours. Calculation forms ar•e provided in the Appendix. Overland Trail is. proposed to be extended from its present terminus (1100 feet south of Dr•.a.ke Road), to the south property 1 i ne of these f i 1 i ngs. This Udou1 d extend Overland Trail an additional 1500 feet. The proposed paving v,ioul d be to a vii dth of 36 feet. The cr•o=.s section necessary to accommodate the expected traffic on Overland Trail should be one lane in each direction. This cross section can be striped on Overland Trail vii th 6 foot shoulders on each side. Table 1 Trip Generation Daily A.H.
