Intersection tangents are measured from flowline of the intersected street at intersections. Note: Two curves in the same direction must be separated by a tangent at least two times the minimum tangent
lengths shown in Table 7-3 and Table 7-4.
These distances are measured as the separation between the centerlines.

Chapter 9 — ACCESS REQUIREMENTS AND DESIGN CRITERIA
Section 9.1 General
CHAPTER 9 — ACCESS REQUIREMENTS AND DESIGN CRITERIA
9.1 GENERAL
Access may occur as one of two types: (1) access for land use (driveways) and (2) public streets
(street intersections).
9.1.1 Designing Placement of Accesses
A. Direct Access Restricted
Direct access to individual lots from Collectors and Arterials is restricted.
B. Avoiding Conflicts in Center Left Turn Lane
When establishing the placement of offset accesses (either driveways or
intersections), ensure that traffic making left-hand turns into the accesses does not
conflict or compete for the simultaneous use of a center left turn lane.
4 C. Separation Distances
The specific separation distances between accesses shall be as shown in Table 7-3 or
Table 7-4. Greater separation may be required to eliminate conflicts or overlaps of
center left turn lanes as determined by TIS.
D. Access Control Plan
For a street controlled by an adopted Access Control Plan, the proposed access shall
conform with the applicable Access Control Plan.
9.1.2 Review and Approval
A. Review Procedure
1. Advice Available. To determine the extent of technical justification required for
all access requests, consult with the Local Entity Engineering staff. It is
recommended that this advice be sought prior to submitting any application.
2. Access Permits. All access permits shall be reviewed and approved through the
Local Entity, in Fort Collins (GMA and city limits) and in Loveland (GMA only).
Loveland (GMA and city limits) does not issue or require a separate access
permit. The requirements of this chapter are covered in the City of Loveland's
design review of the right-of-way permit.
3. Permit Required. A permit must be requested by the Developer and approved by
the Local Entity prior to the construction or reconstruction of any access. See
Chapter 6, Permits.
4. CDOT Approval for State Highway Access. The Colorado Department of
Transportation shall review and approve all State Highway access.

Re: The Center at Rigden Farm
Variance Request —Drive Location
Proj : 1049-034-00
Dear Sheri:
The Center at Rigden Farm project is located on Tract P of the Rigden Farm development
and proposes eleven (11) commercial/retail buildings. A variance is requested from
Table 7-3 "Technical Design Criteria — Corner clearance between driveway/alley and
street intersections — Local Commercial" in the Larimer County Urban Area Street
Standards to reduce the centerline to centerline driveway offset from 175 ft. to 147 ft.
The proposed development will have three ingress/egress drive locations including one
off of Illinois, one off of Limon and one off of Iowa. The driveway entrance off of
Limon Drive is located 147 feet (centerline to centerline) from the intersection of Illinois
Drive. Based upon the traffic analysis for the Northwest Road project, it is anticipated
that the entrance off of Limon will be the least often used of the site's three ingress/
egress locations. Also, due to the presence of on -street parking the speeds are anticipated
to be extremely low. The drive location as shown works most effectively with the
proposed development and will not conflict with the location of future drives to the north
of Limon Drive.
Therefore, in my professional opinion this variance is not detrimental to the public health,
safety, and welfare. Please call me if you have any questions or require any additional
information for the approval of this variance.
Sincerely,
Robert Almirall, PE
