Street Turn Layout Variance
JVA PN: 1980c
Dear Tyler,
This letter is a variance request for the layout of the street turn joining Fossil Blvd. and Conejos
Rd. for the project stated above.
A. Identifying Issue - Per Larimer County Urban Area street Standards (LUCASS), A
minimum inside radius (R1) shall be 20' to 36', the minimum offset radius (R2) shall be
44' based on a 24' wide Conejos Rd, and a total bump out radius (R3) shall be 52'. Refer
to LUCASS figure 7-24 Widening Detail for Street Turns >60 degree (Local Streets
Only).
B. Alternate Design - The proposed design is utilizing the existing inside radius (R1) of
approximately 17'. The flow line along the south side of Conejos Rd. has been tapered
approximately 4.7' to the south over a distance of approximately 73.38'. The taper then
transitions into a 37' radius (R3) that ties into the existing east flow line of Fossil Blvd.
C. Comparing Standards - Based on the standard minimum inside radius (R1) of 20', a
variance is being requested to reduce the radius to approximatley17' to match the existing
flow line radius. A variance is also being requested for the radius R2 and R3 to maintain
a uniform radius around the corner to tie into existing flow lines. The minimum radius R2
is 44' and R3 is 52' and will be altered from LUCASS detail with the south lane on
Conejos Rd. being tapered and a 37' radius to tie -into the existing east flow line. The
proposed layout has a total roadway width at the midpoint of the radius of approximately
42.5'. With the reduction of widening for the street turn, we do not anticipate any impacts
on the capital and maintenance requirements or costs associated with this variance.
D. Justification - Due to existing right-of-way (R.O.W) constraints and existing utility
infrastructure, the minimum required street turn standards cannot been achieved. The
proposed alternative layout will provide an additional dedication of R.O.W. along the
southeast corner of Conejos Rd. and Fossil Blvd. The layout will not required additional
R.O.W dedication from adjoining properties and allow the existing drainage
infrastructure to remain in place. The additional R.O.W. dedication and variance to the

street turn will allow through traffic to continue along Conejos Rd. to Fossil Blvd without
a stop sign as currently exists. The proposed variance will not be detrimental to the
public health, safety and welfare, will not reduce design life of the improvement nor
cause the Local Entity additional maintenance costs.
If you have any questions regarding this variance please contact me.
