Collins, CO 80521 REGARDING: Proposed Owest CMRS facility at 829 S. Shield Street To Whom it concerns: I am the owner of the above referenced property and other adjacent properties to the west and east of the proposed pole location as noted on the Qwest site plan. During my discussions and negotiations with Qwest, it became apparent that setback requirements for the proposed project could not be met. The lot is narrow and can not accommodate the setback requirementanywhere on the lot. I have studied the relevant architectural and engineering documents regarding the pole which were made available to me by Qwest representatives. I've concluded that the pole, if constructed as proposed, poses no danger -to me, to structures owned by me or to my personal well being or to that of my tenants. Qwest has informed me that this pole could fail under certain circumstances but I understand those circumstances to be so outstanding that structures in the immediate area would be demolished prior to such failure. While I might like to ensure the absolute integrity of the pole, I understand that to be impossible and that there are few absolutes in this life. Understanding the engineering andpractical circumstances of this situation, I respectfully request that Qwest's request for modification to standards be granted. Thank you for your consideration. erel (� David J. Bur Owner, 829 S. Shields Street, Ft. Collins, CO STATE OF ea\ ) ss.

These design criteria require loading, W' ice and wind factors which effect the structural strength of the pole. Rohn also designs their poles to fail at pole sections and not at the base of the pole. While this pole in theory could fail, such failure would be precipitated by such violent conditions that surrounding residential and commercial structures would be totally destroyed prior to the pole failure. To the best of my knowledge no monopole has failed in the 10 years that I have been designing and constructing wireless facilities.

Page 6 of 6 SUMMARY The general purpose of the standard for which the modification is requested is a setback requirement that is intended to insure that structures upon adjacent properties would not be impacted by a pole failure and that residents of, or visitors to, those properties would not be harmed by such failure. The plan as submitted promotes the general purpose of the standard for which the modification is requested equally well or better than would a plan which complies with the standard in that: 1. Exhibits A and C established that the pole will survive conditions that would completely destroy adjacent structures and it can be reasonably assumed that prior to the advent of such conditions, residents and visitors would have vacated the structures in favor of safer confines. The pole location as proposed can not reasonably be accessed by vehicular traffic and certainly can not be accessed by traffic traveling at speeds sufficient to cause a pole failure. 2. Exhibit B establishes that the property owner of the proposed site and the adjacent properties has considered the risks of the proposed project and has concluded them to be minimal and wholly acceptable under the architectural and engineering standards as set forth. Page 5 of 6 Exhibit B, is a letter from the owner of the property that will accommodate the pole and of the property adjacent to the proposed site to the west and east. The letter establishes the property owner's understanding of the circumstances surrounding the request, the construction standards of the pole as set forth herein and his support for the modification to standards. Exhibit C, is engineering information which documents the structural integrity of the pole as submitted. Page 4 of 6 BURDEN MET: Applicant believes the aforementioned burden is met as follows: Public Good: The granting of the modification would not be detrimental to the public good. In deed granting the modification to standards would increase accessibility to wireless communications for personal, business and emergency uses which serves the public good. There are no health or safety issues regarding wireless communications. The plan as submitted would promote the general purpose of the standard for which the modification is requested equally well or better than would a plan which complies with the standard for which a modification is requested from a public safety perspective which is primary in this issue. The following exhibits support this finding. Exhibit A is a letter from Qwest's Architect which establishes that if the pole were to fail, such failure would be precipitated by such violent circumstances that adjacent structures would be completely destroyed prior to pole failure. These would include weather related circumstances and natural disasters. Barring such unforeseen and highly unlikely conditions, the integrity of the pole is sure. The pole is not adjacent to major rights of way and there is no reasonable situation whereby vehicular traffic could fail the pole. There are adjacent structures to the east and west of the proposed pole location. These properties are safeguarded from a pole failure in that the pole will survive conditions sufficient to destroy these structures. Page 3 of 6 INTENT: 6 Applicant's intent is to construct a 60' co -locatable, CMRS pole at 829 South Shields in Ft. Collins. This property is zoned CC, Community Commercial which requires a 1:1 setback from property lines. Applicant seeks a modification of standard from the 1:1 setback requirement.under Fort Collins Land Use Code, Article 2, Division 2 (B), Section 2.8.2, Subsection H1. General Purpose The general purpose of the setback requirement is to secure a fallen pole upon the property on which it is constructed. The objective here is to safeguard individuals on adjacent properties and that is advisable from a public safety standpoint and wholly acceptable public policy. Exceptions: Exceptions are made for providers that are able to show that constructed poles will implode upon the property or fail at stress intersections and thus not affect adjacent properties.

Collins, CO 80522 Regarding: Request for modification to the standards Fort Collins Land Use Code Applicable Statute: Article 2.8.2 Modification Review Procedures/Subsection: H1 Under the statute referenced above, the burden of applicant is to show that: The granting of the modification would not be detrimental to the public good and that 1) the plan as submitted will promote the general purpose of the standard for which the modification is requested equally well or better than would a plan which complies with the standard for which a modification is requested. Objective: Applicant's objective is to provide wireless communications to the Shields Street and Elizabeth Street corridors and includes the CSU Campus which is east of the proposed site. In order to accomplish this, the site must be proximate the intersection of the two streets at a height of 60'. Properties in this general area maintain Community Commercial and CSU zoning. The properties are predominately small lots incorporating commercial establishments with a mix of buildings and parking. Vacant lots in this commercial district would generally not be large enough to accommodate a 60' setback anywhere on the properties. Lots adjacent to the intersection are built upon and eliminate the possibility of achieving the required setback. Page 1 of 6
