We believe this variance is justified in this instance due to the actual physical constraints
of the area and the need to meet the general planning guidelines in the US 287/SH 14
Access Management Report. We would further propose that this variance be mitigated
by posting a speed limit in the area appropriate for the actual design.
Please contact me with any questions or concerns.
Best regards,

Re: Proposed Alpine Business Park - Variance Request
Dear Sir or Madam:
This is to request a variance to the Larimer Urban Area Street Standards (LCUASS) for
the above referenced project. Specifically, we request a variance for the minimum
centerline radius specified in Table 7-3 — Technical Design Criteria.
Alpine Street is classified as a collector without parking. A general alignment for this
proposed street is shown in the US 287/SH 14 Access Management Report, dated April 4,
2007. A copy of figure 3-17, entitled "Long -Range Access Control Plan — North College
Avenue", is attached for reference. In general, Alpine Drive is shown as a collector
without parking curving into Mason Street, which is also a collector without parking.
Figure 3-17 illustrates the problem with designing this street in accordance with
LCUASS standards. The centerline to centerline separation between Mason Street and
College Avenue is 430'. The Union Pacific Railroad runs just west of the intersection of
Alpine Street and Mason Street, eliminating the possibility of achieving any additional
separation between Mason and College. In addition, there is an existing alley running
north -south between Mason and College, which needs to tie into Alpine with less than
10* of skew to meet the LCUASS standard. This combination of physical limitations
simply does not allow enough room to achieve a 600' centerline radius.
Our proposed design meets both minimum tangent criteria and the skew criteria.
However, the proposed centerline radius is 200', which does not meet the criteria and
therefore requires a variance.
