Re: Ziegler- Corbett –Intersection Spacing Variance
Dear Staff:
This variance letter pertains to the intersection spacing of the proposed Ziegler-Corbett access and the existing
unsignalized Paddington Road/Grand Teton Place intersection along Ziegler Road.
According to Table 7-3 Fort Collins (GMA and City Limits) Street Standards – Technical Design Criteria in the
Larimer County Urban Area Street Standards (LCUASS), on four lane arterials, the distance between unsignalized
intersections is a minimum of 460’. The estimated traffic generated from the Ziegler-Corbett onto Ziegler Road
will meet the peak hour signal warrant with the proposed intersection aligned with the existing Hidden Pond Drive
intersection. The existing intersection spacing between Hidden Pond Drive and Paddington Road/Grand Teton
Place is approximately 430’. According to Section 8.2.2 Lane Alignment in LCUASS, lanes shall align through an
intersection. This along with the signalization warrant, is requiring the variance of standard from the minimum
intersection spacing.
The traffic memorandum “Ziegler-Corbett Traffic Analyses Related to Inclusion of the Young Property”, prepared
by Delich Associates, dated September 15, 2022, analyzed Ziegler Road access scenarios and is referenced as part
of this variance request. Scenario 2 is the analyses of a signalized access onto Ziegler Road, aligned with the
existing Hidden Pond Road. In this report it is stated:
If the Scenario 2 intersection is implemented, the peak hour signal warrant will be met. It is acknowledged that the
Ziegler/Paddington-Grand Teton intersection is approximately 430 feet to the north (does not meet intersection
spacing criterion). Therefore, a variance will be required due to this. Based upon the operations analyses, the 95th
percentile left-turn queues (northbound to Paddington Road and southbound to Hidden Pond Drive) will not
conflict. The respective queues are not more than 25 feet. This segment can be striped as a continuous two-way
left-turn lane. With a signal at the Ziegler/Site Access-Hidden Pond intersection, it is expected that gaps to the
north/south through traffic on Ziegler Road will occur, which will improve the minor leg operation at the stop sign
controlled Ziegler/Paddington-Grand Teton intersection.
Therefore, it is requested that the reduction from the standard minimum 460’ intersection spacing to the existing
430’ separation be considered.
This variance will not be detrimental to the public health, welfare, and safety. This variance will have no impact
on the capital and maintenance costs of the City of Fort Collins. It is respectfully requested this variance be
granted.
Sincerely,
