Re: City of Aspen Engineering Clarifications Regarding 1130 Black Birch Drive
Dear Black Birch Estates HOA,
The City of Aspen Engineering Department has reviewed the 1130 Black Birch permit plan set for compliance with
the City of Aspen's Engineering Design Standards and International Building Code. The city has requested HOA
approval on the items below.
1. Approval from Black Birch Estates, as owners of Tract C, to allow the proposed box culvert to extent into
Tract C:
In order to accommodate the proposed driveway, which removes the existing driveway from Tract
C as was approved by the HOA, the ditch is required to be relined and culverted. The existing
culvert will be replaced with a box culvert underneath the driveway. The proposed culvert is
located in the same location as the existing, which straddles the property line of 1130 Black Birch
and Tract C of the Black Birch Estates. Any disturbed area around the new culvert will be
revegetated as required by the original HOA approval.
2. Approval from Black Birch Estates, as owners of Tagert Ditch, to allow structures and infrastructure within
the ditch easement:
The previously-approved design includes retaining wall structures within the ditch easement to
support the proposed driveway. These retaining walls are required by code for safety and provide
fall protection for pedestrians and vehicles into the ditch.
The City of Aspen Engineering Department is requesting HOA approval for these two items. Please provide written
approval for the structures within the ditch easement and the replaced culvert, which are consistent with the
original design drawings. Please reference Exhibit A, Engineering Site Plan attached with this letter.
execu ng low, the Black Bl h Est hereby pro es the civil plans:
