*MEMORANDUM*
TO: Richard Grice, Planning Office
FROM: Jay Hammond, Engineering Department
DATE: July 28, 1981
RE: Change in Ski Corp. Pumphouse Plan
A brief comment regarding the change in the elevation of the
structure proposed to house the snowmaking equipment on Little
Nell; following our meeting and site inspection with Joe Harvey,
I would like to offer the following on the elevation changes
as they relate to the previously granted 8040 Approval:
1. As we observed in our inspection, the three -foot raising
of the structure will not significantly affect the visi-
bility of the structure from the appropriate view planes.
Additionally, it seemed fairly apparent, that existing
trees and the protruding contours of the Little Nell
slope will effectively screen the structure from mast of
the town.
2. By changing the proposed grading plan from 'a "pit"
situation, as was originally proposed, to backfilling to
the original contours against the reinforced foundation
walls, the structure will be buried and considerably
less visible even from up close (i.e. from the Little
Nell chairlift).
3. It is true that this office expressed concern regarding
the construction of the original plan adjacent to the
twelve -inch (12 ") City water line from our concrete
1,000,000 gallon tank. The revised plan as is now pro-
posed addresses our concerns and maintains adequate cover
over the existing water line.
In short, the Engineering Office has no problems with the new
plan and feels that raising the structure will in fact alleviate
some potential problems.

Subject: Aspen Mountain Snowmaking Support System
Primary Pumphouse Siting and Grading Revisions
Substance of Changes
- Building elevation raised 3.0 feet from 8088.7 (finished
floor) to 8091.7 (finished floor).
- Building set into hill (was formerly to be set on flat
excavated site; same location). The south wall is now
to be covered to 12 feet and the east and west walls will
be backfilled roughly following the existing contours.
All backfilled walls will be reinforced concrete and all
exposed walls will be painted concrete block (as in the
original plans).
Reasons for Changes
-The floor elevation was changed after consultation with
city engineers who indicated that the original planned
excavation may have disturbed the city's 12 -inch water
main, or promoted erosion.
- It was decided to set the building into the hill to lessen
its visual impact, minimize necessary excavation, and remove
any possible hazard to skiers.
