General Notes
Drainage is not anticipated to present any problems in the proposed Hawk
Ridge Subdivision. The development is located on a topographic high such
that all drainage with the exception of a small draw im the northeast corner
will originate within the development. No wet/ defined drainages exist
so no drainage easements are proposed on any bf the lots.
Culverts on Orchard Lane, Deer Path and Red W mg Land have been sized to carry
flows that were estimated for 100 year story.using methods set forth in the
SCS publication "Procedures for Determining Peak Flows in Colorado". In
addition, these culverts have been sized to carry flows from a breach of
any of the irrigation ditches which lie in their drainage area.
The subdivision is crossed by the C & M Ditch, lark Ditch, a lateral of
the Park Ditch, and a lateral of the C & M Ditch. The only road to cross
any of these ditches is orchard Lane which crosses the Park Ditch lateral
in the southwest corner of the development. This ditch is reported to carry
3 cfs of water to property owned by Mr. Steve Cal+,ic.otte. Mr. Callicotte
is being sent a copy of this drainage plan and is being requested to respond
to the acceptability of installing an 18" CMP to carry water under orchard
Lane. 1M addition, the Park Ditch Company and C &'M Ditch Company are being,
sent copies of this plan so that the width of necessary easements can he
addressed prior to final plat. We will also be dsqussing how culvert
installations for driveways can best be handled.
