Alternative
Location &
Description
Poudre Intake Alternative P-0 begins at the Poudre Diversion Pump Station
location, just southeast of the Timnath Canal. The alignment then stays north
of the Poudre River, passes through the garden center property before
crossing Timberline Rd. From there, it follows the curve between the backs of
residences and the ponds in the Fort Collins Natural Areas. The alignment then
follows the south side of the Cache la Poudre Inlet canal until it crosses to the
north side of the canal prior to crossing I-25. After crossing I-25, the alternative
veers south where it crosses the canal again, and follows the south side of the
canal until it crosses Prospect Road. From there, it continues along McLaughlin
Lane before it turns east and continues to follow another canal until intersecting
with CR 5. After intersecting at CR-5, the alignment heads due east, following
an existing powerline easement before intersecting with County Line Road,
where it ties in with the proposed County Line Alignment.
