RE: Bloom Filing One – Greenfields Drive Curve and Tangent Variance Request
Dear Dave Betley,
Galloway, on behalf of Hartford Homes and in support of the Bloom project currently under
review, is providing the following written justification for the curve radius and tangent length along
Greenfields Drive, per the request of the City of Fort Collins.
A) Identification of the standard to be waived or varied and why the standard is
unfeasible or is not in the public interest.
A variance is requested for the curve radius and tangent length along Greenfields Drive.
Per chapter 7 of LCUASS standards, The City of Fort Collins typically requires a 1075’
minimum centerline radius and a minimum tangent length of 200’ for a 2 lane arterial.
However, due to site specific, spatial restraints (alignment to the north and south of the
railroad crossing, a 1075’ centerline radius and 200’ tangent length is not feasible. Thus a
variance is being requested from 1075’ radii to 600’ radii and 200’ tangent length to 50’.
B) Proposing Alternate Design. Identification of the proposed alternative design or
construction criteria.
Along Greenfields Drive a variance is being requested to allow 600’ centerline curve radius
and minimum 50’ tangent length.
C) A thorough description of the variance request including impact on capital and
maintenance requirements, costs, and how the new design compares to the
standard.
The City of Fort Collins requires 1075’ centerline radius and 200’ tangent length for a
roadway of Greenfields Drive classification. The variance would have this road built with
600’ centerline radius and minimum 50’ tangent length and essentially use the LUCASS
standard for a Major collector. This variance would cause no impact on maintenance costs
as the roadway would still follow the proposed section associated with the arterial section
thus no added or special maintenance would be required.

D) Justification. The Professional Engineer must determine and state that the
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. The proposed plan (as varied) must advance the public
purpose of the standard sought to be varied equally well or better than would
compliance with such standard.
The proposed variance allows Greenfields Drive to function within the spatial restraints
created by the site. The change to a commonly used radius will cause no impact to
maintenance costs. A 2 lane arterial and a major collector (600’ radius road classification)
have posted speed ranges that overlap meaning the variance will allow the roadway to
function with no impact to public health, safety and welfare.
Sincerely,
GALLOWAY
