SUBJECT: AmUSR-1075, R. M. Hiner Construction Company, Inc. The Weld County Public Works Department has reviewed this proposal. This project falls under the Use by Special Review Standard, Weld County Code, Chapter 23, Article II, Division 4, Section 23. Staff comments made during this phase of the Use by Special Review process may not be all-inclusive, as other issues may arise during the remaining application process. COMMENTS: The main access to the facility is from North 23rd Avenue, which is maintained by other. An entrance located at the northeast corner of the site accesses to a private road owned and maintained by Weld County that serves the Weld County grader training course, Weld County gravel pits, Weld County offices, and the County jail. Due to mining safety and jail security issues, use of this road for access to the recreational lake and Hiner pit shall be limited to emergency responder access only. Use of the northeast access may be approved at the County's sole discretion under very limited circumstances with prior written notice to the County. • The applicant needs to address how the proposed USR recreational activities are compatible with the active mining and MSHA regulations. MSHA regulations require that people entering a working mine site be equipped with the proper personal protective equipment such as steel toed boots, safety glasses, hardhats, and safety vests. Portions of this parcel are located within the FEMA mapped Zone A 100-Year floodplain and the floodway. Weld County Code prohibits the construction of buildings within the floodway. Any structures or grading in the floodplain would require a Flood Hazard Development Permit (FHDP). Due to the hazardous nature of the floodplain, potential for loss of life, and potential for damage to public facilities such as bridges, campsites and overnight parking cannot be located in the FEMA 100-year floodplain or the floodway. Portable boat docks must be anchored per an engineered design because the lakes are in the floodplain and, in a flood, the boat docks could move downstream and block flows (e.g. if they become entangled in a bridge). REQUIREMENTS: 1. Utilize the existing accesses to the site from North 23rd Ave. The access off of the County's privately maintained road is to be used for emergency and incidental access only.No new accesses will be granted. 2. As requested at the pre-application meeting and 7-day review, please revise the floodplain labels on the site plan to reference the 2003 Army Corps of Engineers Cache La Poudre River Floodplain Study that has been accepted by FEMA. The note delineating the flcodplain on the site plan references FHDP-615 which is for shop located in the Idaho Creek floodplain located near Longmont, CO. 3. Please add the following development standards to the Plat: • a. There shall be no campsites or overnight parking located in the FEMA-mapped 100-year floodplain or in the flcodway due to the hazardous nature of the floodplain and the potential for loss of life. • b. There shall be no campsites or overnight parking located between the Cache La Poudre River and the lakes due to the potential for riverbank erosion that occurs during a flooding event. c. Portable boat docks must be anchored per an engineered design. A flood hazard development permit must be obtained prior to the installation of the boat docks. d. Pursuant to Chapter 15, Articles I and II of the Weld County Code, if noxious weeds exist on the property or become established as a result of the proposed development, the applicant/landowner shall be responsible for controlling the noxious weeds. All vegetation, other than grasses, needs to be maintained at a maximum height of 12 inches until the area is completely developed. e. WARNING: LOT MAY NOT BE BUILDABLE DUE TO FLOODPLAIN OR FLOODWAY DESIGNATION. Please be advised that owners of Parcel # 080531000063 may not be able to obtain building permits to construct structures. All construction or improvements occurring in the floodplain as delineated on Federal Emergency Management Agency FIRM Community Panel Maps #8082660-0628C dated September 28, 1982 and Map Panel #080266-1529E dated June 10, 2005, shall comply with the Flood Hazard Overlay District requirements of Chapter 23, Article V, Division 3 of the Weld County Code and all applicable FEMA regulations and requirements as described in 44 CFR parts 59, 60, and 65. f. Future development occurring within the floodplain shall be in compliance with the floodplain codes in effect at that time. Future development activities located within the FEMA-mapped floodplain will have to obtain the appropriate flood hazard development permits. g. Prior to the vacation of the mining permit by DRMS, per FEMA's letter dated January 13, 2011; a letter of map revision shall be approved by FEMA showing the impact that the mining operation has had on the floodplain boundaries, floodway boundaries, and water surface elevations. • pc: AmUSR-1075 M:\PLANNING - DEVELOPMENT REVIEW\USR-Use by Special Review\AmU$R-1075WmUsR- 1075.docx • KitLH.

The Division has reviewed the application and offers the following comments: • The Reclamation Permit was issued for the Greeley Pit in 1977 and the site is permitted for 170 acres. To date, no portion of the mine site has been released from reclamation responsibility. The approved post-mining land use for the site is recreation, which allows the site to be utilized for water skiing and camping. The simultaneous use of the site as an active mining operation and for recreation purposes is not under the Division's jurisdiction. Any restrictions on concurrent land uses would need to be addressed at the County level. The proposed changes to the Site Specific Development Plan and the Amended Special Review Permit do not conflict with the Division's interests. However, any changes made to the Mining and Reclamation Plan must be approved by the Division through a Technical Revision. The changes would include the addition of an asphalt and concrete batch plant, relocation of existing gas lines/wells,reconfiguration of the ponds, and the addition of campsites and boat ramps around the north pond. If you have any questions regarding the Division's comments,you may contact me at (303)866-3567 x8116. Sincerely, Michael A.

The site consists of approximately 127 acres that will include an asphalt and concrete batch plant, oil field business, and recreational facility including camp sites and water skiing lake. The referral package included the site plan (3/3/11) by KBN Engineers, questionnaire(undated), and questionnaire • addendum (3/3/11) by KBN Engineers. Portable toilets are indicated on the site plans, so pit toilets or septic systems are not expected. The referral does not indicate any permanent structures will be built at the site. No geologic report was included in the referral. The site is located on a relatively flat surface on the north side of the Cache La Poudre River, and portions of the site are included in the 100-year flood plain. Although the mining area is within the flood plain boundary,the proposed camping sites are outside of the flood plain boundary and the application indicates that only day-use activities will be permitted within the flood plain. The Graham Seep is located in the western portion of the site, and shallow groundwater should be expected throughout the site. No site-specific geologic information was provided for review. Regional maps of the area indicate the geologic deposits on the site are primarily alluvial sands, gravels and silts. Bedrock underlying the site is likely shale, which may have expansive properties. Depth to bedrock is not known. Based on the information provided and the proposed land use, CGS does not have outstanding concerns regarding the geologic conditions that may affect the development, as long as the restrictions regarding the flood plain are followed. If you have further questions regarding this site, please contact me at(303)866-2611.
