Since it is the vehicle projection itself that impacts the available width of the drive aisle, not the stall projection, there is a margin of error provided by using the stall projection. The aisle width increases approximately two feet when compared to the actual projection of the 85th percentile design vehicle. f) The field test that was performed to evaluate the parking geometrics for this project indicated satisfactory maneuverability was achieved at these aisle widths for a GMC suburban. Modification #4: We respectfully request approval of a modification of the stall width for short-term, angled parking from 9'0" to 8'8". We feel this request is justified based upon the following: a) The industry standard width for short-term parking is 8'6". Approximately 44% of the stalls will be 9'0" wide. Another 17% will be 8'10" wide. About 2% of the stalls are oversized for handicap parking and the remaining 37% of the stalls will be at least 8'8" wide. Therefore, 63% of the stalls are 8'10" or wider. By way of comparison, the Old Town parking structure in Fort Collins has 8'4" wide stalls. b) Because it is easier to maneuver into an angled parking stall, field studies by Walker indicate that the vehicle will be positioned more closely to the center of the stall than for 90-degree parking. Therefore, angle -parking stalls can be narrower than 90-degree parking stalls. c) Double line stripes will be used for the parking stall striping to assist parkers with aligning their vehicles in the center of the stall. d) The field test that was performed to evaluate the parking geometrics for this project indicated satisfactory maneuverability was achieved at an 8'6" stall width for a GMC suburban. With approval of an 8'8" by 17'0" stall for 75-degree parking and an 18'3" drive aisle, the required parking module will then be 557'. The attached drawings illustrate that these dimensions are achieved in our design. REMARKS The granting of the requested modifications will not impair the public good nor impair the intent and purposes of the Land Use Code which is to provide parking facilities that are safe, functional, and easy to use. Walker has designed over 3000 parking structures across the United States that safely and functionally meets the needs of millions of people as attested by the owners and customers of those facilities. Since this project addresses an important community need for parking in the Civic Center complex, which is an important element of the city's Comprehensive Plan for this area of the city, we believe that it is in the public interest to grant the modifications requested herein. Therefore, we respectfully request your favorable approval of these modifications. We remain available to answer any further questions that you may have. c:1windowsWesktopWkg-dim2 (2).doc MEMORANDUM WALKER Page 4 of 5 4 PARKING CONSULTANTS November 16, 1998 Parking Stall/Aisle Dimensions d) The stall width and door opening clearance are more important issues for short term parking than stall length. We are meeting the Land Use Code requirement for a 9-foot stall width for 84 percent of the 90-degree stalls. e) The parking industry standards for 90-degree, short-term parking consist of an 8'6" stall width by 17-feet long with a 24-foot drive aisle in a 58-foot parking module. We are providing a 9'0" by 18'0" stall with a 24-foot drive aisle (60-foot parking module) for 90-degree parking. Angle Parking Layout The Civic Center Parking Structure also includes 75-degree angle parking with one way traffic in the two west parking modules. One-way traffic is utilized in order to avoid internal traffic conflicts at the end crossover aisles, thereby minimizing the accident potential, and increasing the ease of use and safety of the facility for both pedestrians and vehicles. Also, because a narrower drive aisle of 18'3" is utilized with angle parking, we are able to create a pedestrian safe zone consisting of a 3-foot wide walkway at the front of the angled stalls, without exceeding typical spans required for precast concrete structural systems. For 75-degree angle, short-term parking, the Land Use Code specifies a 9'0" by 19'0" stall with a 24-foot drive aisle. When the footprint of the stall is rotated to the 75-degree angle, the stall projects into the drive aisle approximately 21'5". Therefore, the LUC requires a 66'10" parking module for 75-degree parking versus the 57- foot module provided. Modification #2: We respectfully request approval of a modification to the Land Use Code for a 17-foot stall length in lieu of the 19-foot stall length for short-term, angled parking. We feel this request is justifiable based upon the following: a) Approximately 90% of the vehicles on the road today are less than 17-feet long. b) The parking stall lines will be painted 2 feet shorter than the actual stall length to encourage patrons to pull farther into the stall. c) The industry standard indicates the parking dimensions should be based upon the size of the 85" percentile vehicle, which is 6'6" wide by 16'6" long in Fort Collins. Modification #3: We respectfully request approval of a modification of the drive aisle width from 24 feet to 18' 3" feet for 75-degree parking with one-way traffic, and to 16-feet for 60-degree parking with one-way traffic. We feel this request is justifiable based upon the following: a) The traffic engineering standard for the width of a one-way traffic lane is 12 feet. We believe the Land Use Code requirement of 24-feet was intended for two-way traffic. There appears to be no provision in the Land Use Code for the width of a one-way traffic aisle. b) It is much easier to maneuver into an angled parking stall than a 90-degree stall. Therefore, the drive aisle width required for maneuvering into an angled parking stall can be much less than for 90-degree parking. c) The parking industry standard aisle width required for maneuverability into a 75-degree angle - parking stall is 18 feet, and 14 feet for 60-degree angle parking. By way of comparison, the drive aisle width for the 65-degree angle parking stalls in the Old Town parking structure in Fort Collins is 15'4". d) A Walker study for Schaumburg, Illinois (available on request) indicated that it is statistically highly improbable that two design vehicles or larger will be parked across the drive aisle from each other. Similarly, it is highly improbable that two, large vehicles will be parked on either side of a vacant stall, which would adversely affect the maneuverability into that stall. Because of the random distribution of vehicles smaller than the design vehicle, there is better than a 95% cAwindows1desktopWkg-dim2 (2).doc MEMORANDUM WALKER Page 3 of 5 4& PARKING CONSULTANTS November 16, 1998 Parking Stall/Aisle Dimensions parking stalls and 90-degree parking stalls, as proposed for the new parking structure. Stall widths were varied from 8'6" to 9'0". A bumper -to -bumper parking module width of 57'0" was used for the 75-degree parking and a parking module width of 60'0" was used for the 90-degree parking stalls (a parking module consists of two rows of parking with a drive aisle between). A full-size passenger car and an LTVU were parked on either side of a vacant stall, and a GMC Suburban then maneuvered into the vacant stall. Based upon that test, it was determined that an 8'6" stall was adequate for the 75-degree angle parking, while a 9'0" stall should be used for the 90-degree parking stalls. REQUESTED MODIFICATIONS TO FORT COLLINS LAND USE CODE The Fort Collins Land Use Code specifies parking stall and aisle dimensions for different angles of park (0, 30, 60 and 90-degrees). The stall and aisle dimensions also depend upon whether the parking will be utilized for short- term, high -turnover parking or long-term, employee parking. The parking industry defines short-term parking as duration of less than 3 hours. High turnover consists of 4-5 vehicles utilizing one parking space in a day (12 to 16-hour period). The Civic Center Parking Structure parking layout consists of 90-degree parking and two-way traffic on a 6% sloped ramp at the East side of the structure, with two flat parking modules on the West side consisting of 75- degree parking and one-way traffic (see attached drawings). The parking module provided for 90-degree parking is 60 feet. This dimension provides for a 24-foot drive aisle with an 18-foot stall length on each side of the drive aisle. The stall width for 90-degree parking is 8'10-1/2" minimum between shear walls at the West Side of the sloped ramp (16% of 90-degree stalls), although a stall width of 9'0" is provided for the 90-degree stalls in other areas. The parking module provided for 75-degree parking is 557' in the middle bay adjacent to the pedestrian walkway, and 57'0" in the Far West bay. These parking module dimensions provide for a 20-foot drive aisle in the west bay and an 18'3" drive aisle in the middle bay with respect to the stall projection of 18'8" on each side of the drive aisle. With respect to the actual vehicle projection (the design vehicle is smaller than the stall), a minimum aisle width of 20 feet is provided. The stall width for the 75-degree angle parking varies from 8'8" to 9'0". During the daytime, levels 2, 3, and 4 of the Civic Center parking structure will be designated for long-term, employee parking. Levels 1 will be designated for short-term parking while overflow short-term parking will be available on the roof (level 5). However, in the evening, all of the parking spaces in the structure will be available for short-term parking. 90-Degree Parking Layout The Fort Collins Land Use Code (LUC) specifies a 9-foot wide by 19-foot long stall for short-term parking with a 24-foot wide drive aisle for a 90-degree parking layout. The LUC-required parking module width is then 62 feet versus the 60-foot module provided in our design. Modification #1: We respectfully request a modification to the short-term parking requirements to allow an 18-foot stall length in lieu of a 19-foot stall length for 90-degree parking. The required parking module width would then be 60 feet. We believe this request is justifiable based upon the following: a) Approximately 98% of the passenger cars, light trucks, vans and sport -utility vehicles on the road today are under 18-feet long. b) The parking stall lines will be painted 2 feet shorter than the actual stall length to encourage patrons to pull farther into the stall. c) The industry standard indicates the parking dimensions should be based upon the size of the 85`h percentile vehicle in use in Fort Collins which is 6'6" wide by 16'6" long (requires 8'6" by 16'6" stall). c:1windows1desktopWkg-dim2 (2).doc MEMORANDUM WALKER Page 2 of 5 4 PARKING CONSULTANTS November 16, 1998 Parking Stall/Aisle Dimensions Walker has also tracked sales for light trucks, vans, and utility vehicles since 1987. LTVU's are generally wider than passenger cars. While trucks are a little longer, vans are approximately the same length as passenger cars, and sport utility vehicles (SUV) are shorter than the automobile design vehicle. The design vehicle for light trucks is 66" wide by 16'10" long, or about the size of a Ford F150 pickup truck. The design vehicle for vans is 6'Y by 168". The design vehicle for SUVs is 6'4" by 1610" or about the size of the Toyota Land Cruiser. When the mix of automobiles and light trucks is considered, the design vehicle inches up in width but down in length to 6'3" wide by 167' long, or about the size of a Ford Windstar minivan. The GMC suburban is one of the largest passenger vehicles at 68" wide by 18'3" long. However, compact vehicles (less than 15-feet long) represent approximately 45% of vehicle sales since 1980. Stall Width The stall width is determined by adding half of the required door opening clearance to each side of the design vehicle (Note: Half of the door opening clearance is "borrowed" from the adjacent stall, except when the stall is adjacent to a wall). Parking industry standards indicate that a door opening clearance of approximately 24" is adequate for short-term, high -turnover parking, and a door opening clearance of 20" is adequate for long term, employee parking. Based upon the size of the current composite design vehicle, a stall width of 8'Y is calculated for short-term parking, and a stall width of 7'11" is calculated for long-term parking. Local Vehicle Mix The foregoing analysis assumes that the mix of vehicles in Fort Collins is consistent with the national mix of vehicles on the road. This assumption is not necessarily true. Therefore, Walker performed a field survey on June 25, 1998 of the vehicles in the existing parking lot at the site of the proposed parking structure to determine the mix of compact cars, full size cars, and light trucks at this location. The results are as follows: Compact Vehicles Cars 66 38% LTVU's 14 8% Subtotal 80 46% Full Size Vehicles Cars 29 17% LTVU's 64 37% Subtotal 93 54% Nationally, there are approximately 28% LTVU's registered (see enclosed newspaper article), while in the state of Colorado there are approximately 35% LTVU's registered. Approximately 45% LTVU's were observed utilizing the existing parking lot. Therefore, the number of LTVU's in Fort Collins is well above the national average as well as above the average for the state of Colorado. The amount of compact vehicles is very close to the national average. Therefore, a slight increase in the width of the design vehicle should be made (to 6'6"), with a corresponding increase in the recommended stall width (to 8'6" for short-term parking). Field Test A full-scale field mock-up of the recommended parking geometrics was performed on June 12, 1998 in the parking lot at the City of Fort Collins streets department. Members of the design team and City of Fort Collins parking, transportation, and engineering staff observed the field test.

We request that the City of Fort Collins grant a modification to the parking dimensional standards in the existing Land Use Code for this project based on the design rationale presented herein. BACKGROUND The parking space dimensions are based upon the following publications: 1. Recommended Guidelines for Parking Geometrics, by the Parking Consultants Council of the National Parking Association, Washington, DC, August 1989. 2. Guidelines for Parking Facility Location and Design, by the Institute of Transportation Engineers, Washington, DC, May 1990. 3. The Dimensions of Parking, Third Edition, by the Urban Land Institute and National Parking Association, Washington, DC, 1993. 4. Parking, by Robert A Weant and Herbert S. Levinson, Eno Foundation for Transportation, Westport, Connecticut, 1990. 5. Parking Structure: Planning, Design, Construction, Maintenance and Repair, Second Edition, by Anthony P. Chrest, Mary S. Smith, and Sam Bhuyan, Walker Parking Consultants/Engineers, Inc., 1996. The information contained in the above publications is collectively referred to herein as the parking industry standards. Design Vehicle The parking dimensions in the above publications are based on the design vehicle which is the size of the vehicle representing the 851h percentile largest passenger vehicle in use. Walker Parking Consultants (Walker) has been tracking automobile sales for each car model since 1976. The 85th percentile design vehicle based upon that data (through 1996) is 6'1" wide by 16'8" long, or about the size of a Mercury Sable c:1windows1desktopWkg-dim2 (2).doc FENTRESS BRADBURN ARCHITECTS, LTD.
