No parking or staging of commercial vehicles on the county road is allowed. Use on-site parking area. PRELIMINARY DRAINAGE: The applicant has provided a preliminary drainage report and plan for the Dietzler Water Resources project. The preliminary drainage report was not signed, stamped, and dated by a registered professional engineer licensed in the State of Colorado 1. Please address the redline comments on the drainage report and drawings that were returned to the applicant's engineer. Future drainage report submittals must be stamped, signed, and dated by a registered professional engineer licensed in the State of Colorado. 2. Please ensure that the Final Drainage Report addresses all items in the Preliminary and Final Drainage Report Checklists. 3. Please provide design calculations for all swales and channels that will be constructed on the site. 4. Please show the detention pond in a drainage easement on the final plat and label the volume and release rate. 5. Please include a map delineating the off-site drainage basins that drain onto the site. 6. The preliminary drainage report appears to be utilizing rainfall amounts for the town of Firestone. It is not appropriate to utilize Firestone rainfall for a proposed site that is over 60 miles northeast of the town. Please utilize the appropriate rainfall amounts shown in the NOAA atlas. Grading Permit: Prior to recording of the final plat, the applicant needs to submit a grading permit showing: proposed grading, erosion control placement, typical details for all BMPs to be utilized, and a Construction Stormwater permit from the Colorado Department of Public Health and Environment.

All issues of concern and critical issues during further review must be resolved with the Public Works Department. COMMENTS: The final drainage report was submitted for review on January 6, 2011. The report was stamped, signed and dated by Frank Buturia, P.E. #31475. The drainage report could not be fully reviewed due to miscalculations in the historic release rate. Proper calculation of the historic release rate is the basis for all subsequent calculations made for sizing the detention pond. The historic release rate calculated in the drainage report was based on the 80 acre parcel boundary not the 9 acre project site. The detention pond size was calculated using the historic runoff rate for the 80 acre site and a 9 acre runoff area. In order to properly calculate the historic release rate, the same acreage should be used in both the historic release rate and detention pond sizing calculations. In this case, the historic release rate and detention pond sizing calculations should have been based on the proposed project area of 9 acres. However, to be consistent with water hauling USR applications that were reviewed subsequent to this application, Public Works will allow the applicant to provide a water quality pond that is at least 6,000 cubic feet in size in lieu of the full size storm water detention pond. Although a water quality pond can be utilized at this point, the applicant should be aware that future development which increases the impervious area on the site may require upgrading water quality pond to a full sized storm water detention pond. If the applicant chooses to provide only a water quality pond at this time, please show the water quality pond on the plat. Place the water quality pond in a drainage easement that is delineated on the plat and labeled as a "No Build or Storage Area". Also label the capacity of the water quality pond on the plat. If the applicant chooses to provide a full size storm water detention pond at this time, please correct the calculations to properly reflect the historic runoff rate and the correct detention pond sizing. Improvements Agreement: This Use by Special Review will be subject to a designated haul route and any intersection improvements such as adequate turning radiuses, dust control if needed, on-site improvements or upgrades necessary to accommodate this type of use. Grading Permit: Prior to recording of the final plat, the applicant needs to submit a grading permit showing: proposed grading, erosion control placement, typical details for all BMPs to be utilized, and a Construction Stormwater permit from the Colorado Department of Public Health and Environment. The permit must be stamped by a registered professional engineer licensed in the State of Colorado.
