Request for Variance from Grading Standards
SE Project No. 19120.03
Dear PJ,
Sopris Engineering is writing to request a variance from the City of Aspen’s Grading Standards for grading
improvements proposed on Park C associated with the Burlingame Ranch Phase III Project. The requested
variance pertains to the maximum allowable finished grade slope as noted within Section 5.2 on page 40 of the
City’s Engineering Design Standards.
During the project’s insubstantial amendment process the City was looking for opportunities to reduce the
number of proposed boulder walls located throughout the development to include Park C due to a deficit in the
number of available boulders. As a result, our office performed grading studies and presented an alternative
grading design that eliminated the majority of boulders proposed on Park C. However, the grading revisions
required 2:1 slopes in some areas to avoid disturbing areas outside the platted AVLT slope grading and
maintenance easement. This redesign was presented to the City and accepted during the insubstantial
amendment process. In addition, it should be mentioned that the Parks department supported the redesign as
it provided additional design opportunities should the parcel be developed as a Park in the future. The areas of
2:1 slope includes temporary and permanent erosion control measures to minimize the risk of erosion and
sediment transport. These measures include erosion control blankets, temporary irrigation as well as
landscaping ground cover.
Given the requests by the City to reduce the number of boulder walls and interest of City Parks to minimize the
overall disturbance on Park C, which ultimately provides them with the utmost flexibility with any future design
efforts should the land be developed as a park, we believe that a variance to allow 2:1 slopes is both
reasonable and necessary.
We appreciate your consideration of our request and please don’t hesitate reaching out with any questions or
need for additional information.
Sincerely,
Sopris Engineering, LLC
