The Department of Planning Services is in receipt of your letter dated October 13,2002 and offers the following comments specific to the re-platting of existing lots. Your letter to Brenda Archuleta of Security Title Guaranty Company of Brighton stated that there are two individuals who want to purchase three lots for two hangar buildings. Each owner would purchase the end parcel and sham an Interest in the interior parcel. The Department of Planning Services in their letter dated April 3.2000 from Robert Anderson, Planner stated'The Weld County Department of Planning Service's Staff has determined that Platte Valley Airpark's request to change the proposed hangar configuration on Block 2, (Lots 1-6)from six small hangars to one large or two to four small hangars does not constitute a substantial change from the original application as long as the combination of lots required for the proposed larger hanger or hangers are sold as a single unit to a single buyer and that the platted lots are not reconfigured." "The platted lots shall remain as separate legal parcels. Reconfiguring the lots would require Re- Subdivision with all associated applications, requirements and fees." "One potential area of concern,for planning staff,was if any utilities or utility easements between the lots were in place." The proposal to combine three existing lots into two new lots for the purposes of constructing two new hangers owned wholly In part by two individuals does constitute a substantial change from the original application. Given this proposed action to reconfigure the lots, the Department of Planning Services will require a Re-Subdivision application and re-platting of the PUD, Should you have any questions or need further information, I may be reached at the above address, telephone number or e-mail address.

Your request was forwarded to the Department of Public Works for consideration and review. This office received a memorandum from the Department of Public Works concerning your request dated September 3, 2002. The Department of Public Works notes that Platte Valley Airpark has contacted Drexel, Barrell & Company to engineer and design a new detention pond and supply an appropriate drainage plan for the airport. The Department of Public Works foresees no problems with the relocation of the detention pond as long as it remains within the PUD application boundary as delineated on the S-409 plats. However, Drexel, Barrell &Company will be required to supply a new drainage plan and study verifying that the f';ilitywill retain and release at the h 'urIcal :ate any run-oil associated with the drainage report to t`,t: ;.partment of Public Works for review and approval prior to construction. Given this revision to the existing plats,the Department of Planning Services and the. Department of Public Works requests that the new detention pond area be bonded to insure the construction on site. An Improvements Agreement may be obtained through the Department of Planning ::::r'ices or the office of the Clerk to the Board.

PLATTE VALLEY AiRipARK August 26,2002 " Mr. Kim Ogle, Senior Planner WELD COUNTY DEPARTMENT OF PLANNING SERVICES 1555 N. 17T"AVENUE Greeley, CO 80631 Dear Mr. Ogle: I am contacting you in regard to the existing PUD S-409 for Platte Valley Airpark, as you are familiar with the history of this project. If I should be directing this correspondence to someone else, I would appreciate your assistance in forwarding this letter and advising me accordingly. We are requesting permission to modify the current PUD by relocating the proposed detention pond to a southeast location to allow the existing T-Hangar structure to remain in place parallel to the east/west taxiway. This T-Hangar unit is a major source of revenue for the airport and, if possible,we would like to avoid the expense of relocating it to another location. As you may recall, this modification was previously requested in our letter to Weld County Department of Planning Services, dated January 17, 2000. Subsequently,this request, along with several others,was,denied in your letter of February 11, 2000, advising that an amendment to the PUD would be required. Since this time, we have learned the Grading and Drainage Exhibit/Map outlining the proposed detention pond was never formally recorded with the PUD. It was on file with Public Works, but was never formally reviewed or approved by the Board of County Commissioners. I.have talked with Lee Morrison, and based on this discovery, he suggested that we once again try for this minor variance to the PUD. Lee Morrison can give you additional information on this unusual circumstance if necessary. Please be assured that we have no intention of eliminating the detention pond or altering the natural/historical flow of drainage on the airport property. We only,desire to relocate an identical drainage system for the benefit of the airport operation. Enclosed, you will find a proposal from Drexel, Harrell & Company, to engineer and design a new detention pond and appropriate grading plan for the airport. Our contact, Gary Odehnal, has 7507 WCR 39 O Ft. Lupton CO 80621 O Phone/Fax 303-536-0380 E-mail: mtpva@aol.com O Q reviewed the original grading and drainage map and PUD application material,including the drainage study, and has assured us that the pond can be relocated to achieve all of the original requirements for flow and release at the historical rate. Based on these facts and arguments, we are hopeful that the Department of Planning Services will approve our request. Please let me know if you require any additional information. I look forward to hearing from you in the near future.
