Re: Rifle Creek Estates Filing 2 - Final Plan Submittal
ROBERT B. SZROT, County Engineer
Dear Kit;
I have received/reviewed the following documents:
1) August 2nd Final Plan Submittal, Atkins & Associates - Sheets 1,3,4,5,6,&7
2) Filing 2 Submittal, D.H. Surveys Inc. — Sheets 1&2
3) Building & Planning Review Agency Packet of 8/19/99, 5 pages
4) Final Plan Submission Booklet, Fowler & Marais
5) Rifle Fire Protection Letter, August 31st, 1999
6) My past review letters — June 1St, & June 7th, 1999
My attention was focused on three items that needed clarification in this final stage:
1) The issue of the second added seasonal fire hydrant was resolved with a letter from
Mike Morgan, District Fire Chief. I wanted to assure that the fire department would be
comfortable with an additional hydrant that was only operable during summer
months. The fire department's August 31st letter clarified their acceptance of this
concept. Year-round fire protection had been previously documented and provided.
2) The cross section of Mesa Drive was shown to have 8" of class 2-3 minus, 4" of
class 6, with an asphalt chip seal. 11' lanes with 1.5% crown and 4 foot shoulders
are provided. All base layers in addition to the insitu roadbed soil will be compacted
to 95%. I would advise that compaction testing be accomplished on the insitu earth
layer and all base layers to assure proper densities are achieved.
3) Clarification of the potable water system supply lines was provided by the revised
blueprint sheets. Supply lines were now shown as 8" lines and the connectivity with
the new water tanks was also more clearly illustrated. Potable supply tank flow will
typically enter tank #1, flow through tank #2, and exit to the residential supply line
through tank #3. Flow check valves and redundancy is also built into the system to
address taking 1 or 2 tanks out of service for repairs or maintenance.
After reviewing the above documentation I would support approval of the Final Plat for
this development.
