Dear Mr. Sparone, This letter is in response to the variance request dated November 22, 2005 to reduce the required utility easement adjacent to JFK Parkway edge of ROW. After discussion with the concerned utility providers for the site, the variance request to reduce the width of utility easement from 15' to 9' has been granted. The granting of this variance request does not set any precedent or change the application of our design standards in other situations. If you have any questions, please contact Dan DeLaughter at 221-6605. SY Dan DeLaughter cc: file November 22, 2005 RN Mr. Marc Virata J-R ENGINEERING CITY OF FORT COLLINS ENGINEERING DEPARTMENT nwe>t„a„Cn,, "'n, PO Box 580 Fort Collins CO 80522 RE: I" Community Bank Plaza — Variance request for utility easement Dear Mr. Virata: The intent of this letter is to request a variance regarding the required utility easement along the frontage of the above project. Per chapter 7 of the Larimer County Urban Area Street Standards, a 1541 utility easement is typically required along a four lane arterial such as JFK Parkway. A 9-ft utility easement has been proposed with this application. Support for the variance described above is discussed in the line items listed below: 1) The only utilities that will utilize the area behind the sidewalk will be communications. Per our discussions with Xcel Energy, a 6" gas main already exists along the eastern edge of JFK Parkway. This gas main will be extended south and a gas lateral will be bored under the roadway to provide service for the propose project. Xcel Energy does not anticipate utilizing the utility easement associated with this project in the future. We have also coordinated with Fort Collins Light and Power and the proposed electrical service will be located within the JFK Parkway Right -of -Way. Therefore, we feel that a 9-ft wide utility easement is more then adequate for communication services. 2) We have contacted Comcast Cable and they have verbally approved the 9-ft utility easement based on the fact that gas service will not be located in same. 3) The reduced easement has enabled the design team to locate the proposed site improvements further to the east and provide a larger buffer area along the irrigation ditch to the west. It has also allowed the design team to overcome various complications (irregular property shape, ditch access, connecting to existing conditions, etc.) that are inherently associated with an infill project. 4) No negative impacts to public health, safety, and/or welfare are anticipated. 5) No additional maintenance costs are anticipated. 2620 East Prospect Road, Suite 190, Fort Collins, CO 80525 970-491-9888 • Fax: 970-491-9984 • w jrengineering.mtn If you have any questions or comments, or need additional information, please do not hesitate to contact our office.

Sincerely, JR ENGINEERING, LLC /Z� C.Sparone Engineer W a V J W December 30, 2005 File: 0592LT02 Dan DeLaughter v Fort Collins Engineering Department co RECEIVED 0 `n Eric Bracke, P.E., PTOE co co Fort Collins Traffic Engineer JAN 0 3 2006 CD Ted Shepard, Chief Planner Fort Collins Planning Department x P.O. Box 580 _...__ ti Fort Collins, CO 80522-0580 Dear Dan/Eric/Ted: This letter is a variance request with regard to the minimum off - co 0 street parking setback distance at the south access driveway for the N m First Community Bank Plaza west of JFK Parkway in Fort Collins. The co site plan and subject area is shown in Appendix A. JFK Parkway is co o classified as a four -lane arterial street. The south access driveway rn will likely have a daily traffic volume in excess of 750. Therefore, according to Figure 19-6 in the "Larimer County Urban Area Street Z Standards," the minimum setback to the first parking space should be 0 100 feet. According to the site plan, the first parking space along d the access driveway is 50 feet from the flowline of JFK Parkway. Compliance with the standard would eliminate six parking spaces along the south side of the access driveway. In addition to this, the first parking spaces in the parking lot to the north are 80 feet, as measured along the centerline, from the flowline of JFK Parkway. Compliance with the standard would eliminate four parking spaces (two on each side of the drive aisle) in this parking lot. Therefore, a total of ten parking spaces would be eliminated by meeting the standard. The primary reason for this parking setback distance is to not have a condition that would cause entering vehicles to back into the arterial street, thus creating a potentially hazardous condition. This variance request analyzes the probability that this situation would occur during the peak hours. The analysis was conducted for Z both the morning and afternoon peak hours. The parking maneuver is ¢ accomplished in a relatively short time period, requiring not more W than a few seconds. It is the unparking maneuvers, requiring W Z backing, which takes time to accomplish. For analysis purposes, it Zwas assumed that an unparking maneuver takes 30 seconds to W accomplish, although experience would indicate that most take less ZZ time. Therefore, the following is considered to conservative. From a the site plan, there is 50 feet between the first parking space and the flowline of JFK Parkway. Given Fort Collins Engineering Ir n Department staff comments regarding a previous variance letter (dated Z 12/22/05), the site plan will be changed to eliminate two of the a parking spaces along the south side of the access driveway. This F would result in a parking setback of 70 feet from the flowline of JFK ca Parkway. This is enough space to store three ingressing vehicles U without spilling into JFK Parkway. The analysis assumed that the afourth vehicle would spill out into the right southbound lane of JFK ¢ Parkway. This only impacts the parked vehicles along the access I— driveway. The parked vehicles in the lot to the north are not impacted unless five or more vehicles enter at the same time, which is the same as if the standard was met. Therefore, these four parking spaces were not considered in this calculation. Therefore, a total of four parking spaces are impacted. Appendix B contains the calculation sheets for the following analyses. There are 120 - 30 second windows (unparking maneuver time) in each hour. Given the number of available parking spaces and the number of exits from the site (both driveways), the probability of any of the eight subject spaces having a parked vehicle that will execute an unparking maneuver is 0.0083 in the morning peak hour in any given window and 0.0250 in the afternoon peak hour in any given window. There will be 55 and 50 entering vehicles in the respective peak hours. Since it is not likely that the entering vehicles will enter the access driveway evenly spaced over the entire peak hour, a peak hour factor of 0.50 was used in this analysis. This has the effect of doubling the number of entering vehicles in the peak hour. The probability that four vehicles will enter within any 30 second window is 0.6682 in the morning peak hour and 0.3845 in the afternoon peak hour. The probability that four vehicles will enter in the same 30 second window that an unparking maneuver would occur is 0.0055 in the morning peak hour and 0.0096 in the afternoon peak hour. The potential conflict would occur 1 percent of the time in the either peak hour using the conservative input values described above. Therefore, it is expected that this conflict may occur in 0.67 = 1 of the available 120 windows in the morning peak hour and 1.15 = 1 of the available 120 windows in the afternoon peak hour. If the standard is met, the number of on -site parking spaces will be reduced, which has the effect of increasing the probability that an unparking maneuver will occur from any given parking space. By meeting the standard, the fifth entering vehicle in the same window will spill into JFK Parkway. The probability of the one subject parking space having a parked vehicle that will execute an unparking maneuver is 0.0083 in either peak hour. The number of entering vehicles remains constant. The probability that five vehicles will enter within any 30 second window is 0.5902 in the morning peak hour and 0.2948 in the afternoon peak hour. The probability that five vehicles will enter in the same 30 second window that an unparking maneuver would occur is 0.0049 in the morning peak hour and 0.0024 in the afternoon peak hour. Under this circumstance, it is expected that a conflict would occur one time in the morning peak hour and 0-1 times in the afternoon peak hour. This is only not significantly different than that which would occur with the requested variance. From this analysis, it is concluded that the parking setback of 70 feet, shown on the site plan, is not detrimental to the public health, welfare and safety. It is respectfully requested that this variance be granted. Please contact me with questions or if you require additional information regarding this variance request. Thank you. Since ly, Matthew J.
