RE: Grading Permit, Sweetwater Ranch — New Leaf Lane
Dear John:
This office has reviewed the documents provided for the Grading Permit application of New Leaf
Lane for Sweetwater Ranch. The submittal was found to be thorough and well organized. The
review generated the following comments:
1. The plans refer to a wetland mapping report. A copy of this should be provided.
2. Culvert G3 on the plans is understood to be for irrigation and is not included in the drainage
report. However, sizing seems to be uncertain from the plan note. The appropriate culvert
diameter should be determined and the size included on the plans.
3. There is a detail provided for culvert outlet protection in the plans but it is unclear from the
notes on the plan sheets if the contractor is intended to construct this outlet protection along
with the flared end -sections. Since the culvert slopes are steep, that is believed to be the intent;
and the plan note should be changed to refer to end sections and outlet protection.
4. A detail for construction of the roadside cut -ditch should be included or added to the typical
section detail.
5. The erosion control plan should be evaluated to determine if BMPs may be warranted to
mitigate erosion within the roadside cut ditches.
6. Plan notes on cover would be better changed to refer to the County instead of City.
7. It is believed that the Applicant either has or will have a CDPHE permit. A copy of the permit
should be provided to Garfield County.
Feel free to call if you have any questions or comments.
Sincerely,
