This memorandum addresses the transportation impacts of the
Cv
proposed Ridgewood Hills, Tracts N & T. It contains all of the
0
(0
information required in an intermediate transportation impact study.
Ridgewood Hills, Tracts N & T is proposed to be located in the east
aand
south quadrants of the Triangle/Avondale intersection in Fort
_F
o'
Collins. The site location is shown in Figure 1. Ridgewood Hills is
z
w
a developing residential neighborhood. Ridgewood Hills, Tracts N & T
CD
o
will consist of 28 single family dwelling units and 41 townhome
cv
n
dwelling units. The scope of this study was discussed with the Fort
N
Collins Traffic Operations Engineer. The base assumptions form and
cv
related information is provided in Appendix A. There are sidewalks
along developed parcels of land within 0.25 miles of the site. There
are bike lanes on Triangle Drive and Avondale Road.
Figure 2 shows recent peak hour counts at the key
intersections. The count data was obtained in June 2004. Raw
traffic data is provided in Appendix B. Table 1 shows the current
peak hour operation of the key intersections. Calculation forms are
provided in Appendix C. A description of level of service for
unsignalized intersections from the 2000 Highway Capacity Manual and a
table showing the Fort Collins Motor Vehicle LOS Standards
(Intersections) are also provided in Appendix C. The US287/Trilby and
US287/Triangle intersections are considered to be in a "commercial
corridor." The Trilby/Avondale-Constellation and Shields/Trilby.

intersections are considered to be in a "low density mixed -use
