RE: RUDOLPH FARM PROJECT
MINIMUM VERTICAL CURVE K-VALUE VARIANCE REQUEST
NORTHERN PROJECT #1896-001
To whom it may concern:
Northern Engineering would like to present this request for a variance for the Rudolph Farm project. General information
about the project is presented below, and detailed information about the nature of this request follows.
General Information
The project site is located at the northeast corner of Prospect Road and I-25 in Fort Collins. The site currently is used for
agriculture, and this project is slated to develop multi-use “super-pad” sites which will include, commercial, retail, and
residential developments. The entire project site consists of approximately 115 acres.
Prospect Road
Part of the project includes widening Prospect Road at the south frontage of the property. In order to connect to the existing
improvements that were installed with the new bridge across I-25, two vertical curves must be used. In order to meet all
other LCUASS requirements, the K-Values on the vertical curves immediately east of the I-25 connection are slightly lower
than shown in LCUASS requirements.
Carriage Parkway
Carriage Parkway is the primary connecting road from Prospect Rd. to the north for this proposed development. The site
features very little vertical fall across it, so in order to achieve positive drainage, fill must be brought in to raise the north side
of the site. As such, the connection point in Carriage Pkwy to the development immediately to the north differs in elevation.
We are trying to get the high point of the road as close to the north property boundary as possible to achieve proper drainage
patterns. The vertical curves needed to achieve this meet the minimum required length for the design speed of the road, but
the K-values for each curve are lower than the requirement. Extending the curves out far enough to achieve required K-
values would cause major challenges through the rest of the design.
We would like to request a variance to the LCUASS K-value requirement for vertical curves in these two areas in order to be
able to meet other LCUASS requirements and achieve optimized design.
If you have any questions, please feel free to contact me directly.
Sincerely,
NORTHERN ENGINEERING SERVICES, INC.
