Dear Mr Goranson:
Thank you for referring Diamond Peak Properties, LLC' s
application for a Recorded Exemption, Case Number RE-1979 , to us
for review. After our review of the application and a site visit
by Natural Resources Conservation Service personnel, we have the
following comments :
SOIL LIMITATIONS
****************
While there are no plans currently for construction on Lot
B, approval of this application would make future construction
possible . Both Colby loam and Weld loam present severe
limitations for septic system development because of slow
percolation. However, Weld loam has moderate limitations for
houses with or without basements because of shrink-swell
potential, while Colby loam has only slight limitations . Should
construction occur, it should be limited to the areas of Colby
loam found along WCR 18 and in the northeast corner of Lot B.
Building along WCR 18 would also eliminate the need for an access
road for which Colby loam has moderate limitations because of low
strength.
REVEGETATION
************
Land between the poultry houses on Lot A is being farmed
with Lot B using a winter wheat/fallow crop rotation. If Lot A
is sold off, it is possible that this land will no longer be
farmed. Since the Colby loam on Lot A is considered highly
erodible, we recommend that this land either be farmed as before
or revegetated. We are including a grass seed mix and
instructions for planting should the new owner choose to
revegetate this land.
Thank you again for giving us the opportunity to comment on
this matter. If you have any questions or need comments on
another application, please contact us at the above address .
Sincerely,
1 004N

RECOMMENDED PRACTICES FOR .,BASS SEEDINGS
COVER CROP
If possible, plant a cover crop of long season grain sorghum, or
forage sorghum from mid-May to mid-June before planting grass during
winter. This cover will hold the soil and grass seed in place while the
grass becomes established. Mow the cover crop before physiological
maturity is reached to a height of 12" to 18" to prevent sorghum seed from
sprouting next summer. Seeding rates should be eight pounds per acre on
sandy soils and 15 pounds per acre on clay soils . Planting should be done
from northeast to southwest if possible, or west to east if not .
PLANTING
********
Sometime between November 1 and April 30 when the ground is unfrozen,
plant the grass 1/4 to 3/4 inches deep in 7" to 12" rows . Planting should
be done from northeast to southwest if possible, or west to east if not .
Use a grass drill equipped with an agitator box, depth bands, and double
disc furrow openers with the drop tube placement directly between the
disks .
MULCHING
********
New seedings not planted into a cover crop should be protected by a
mulch of 4000 lbs . per acre weed-free native grass hay crimped into the
soil surface . Crimping the hay into the soil surface will help prevent it
and the grass seed from blowing away. It will also slow evaporation which
will leave more water for seed germination, and retard weed germination and
growth.
WATER EROSION
*************
Mulching may not be enough to prevent erosion on steep slopes or in
areas of periodic water flow. In these areas, install silt fences
perpendicular to the direction of water flow. This will help to prevent
water from building up enough force as it flows to wash out the mulch or
grass seed.
FERTILIZER
**********
Because many weed species emerge before the grass will, any fertilizer
applied will be utilized by the weeds, making them even more competitive .
No fertilizer is recommended for native grass seedings in this area.
WEED CONTROL
************
Until the grass seedlings have reached a five leaf growth stage mowing
is the preferred method of weed control . Mowing off the tops of the grass
plants should be avoided. Timeliness of any weed control option is
essential . Contact Colorado Cooperative Extension Service for herbicide
recommendations, or NRCS for the best time for mowing operations .
Weeds will need to be controlled with mowing or herbicides until the
grasses are established, usually the first four years after planting. Once
established, the grass can withstand heavy traffic or grazing.
