On behalf of Hadid Aspen Holdings, our letter is to requlult consideration of the attached language as an amendment to the text of the City of Aspen Land Use Regulations under the provisions of Article 7, Division 2. The request has to do with allowing consideration of II reduction in the dimensional requirement.s for parking "'paces by Special Review if certain conditione are met. In support of this amendment we are forwarding the relevant information r"'quired under Section 6-202 as well a8 information frolD.

Nationally, oompact parking ill a range of 25' to 40\ of total spaces provided is considered acoeptable if the spaces are 8 feet wide by 16 feet long hi 7 feet high: if the width i. reduced to 7 1/2 feet. the publication states that the percentage should be no higher than 25\. For local U8e, we are 8uggesting that the low end of the range, or 25%, should be used as the maximum to be considered for B' x 16' spaces and that no more than 20\ should be considered if the width is reduced to 7 1/2 feet. In addition, we at'e ,"uggesting sevet'al other conditione that would prohibit a reduction in the size of the spaces if the parking ill exterior, iB imediately adjacent to a public lItreet or alley, is unpaved or is not totally free of any obstructions.

If the small stall is 7-1/2 feet wide (vs. 8 feet), then maximum percentage should be 25 percent. Small car stall dimensions range from 7'-6" to 8'-0" in width and 15'-0" to 16'-6" in length. Facilities such as the Ritz with anticipated low daily turnover rates (less than three to five turnovers per stall per day) could JUstl1'y the smaller dimensions (reference #2). Small car stalls should be of consistent size and should be at least one foot narrower than a large car stall, i.e. if the large car stalls will be 8-1/2 feet wide, the small car stalls should oe 7- 1/2 feet wide (reference #2). Small car stalls should be located and sized so that they always fill before the entire facility. Otherwise, large cars will be forced to use small car stalls (reference #2). I trust this provides the reference information you need to provide to Jay Hammond for the City's review. Please call if you bave any questions. 1. 2. 3. 4. Sincerely, ~;:~~~ David D.

Washington, D.C, 20005 ii The criteria that a stall be 7.5 feet wide and ap- proximately 16 feet long should be adequate to accommodate all c.ars classified as Class 8 or smaller. As a maller of fact, some of the cars in Class 9 could fit into the stalls without causing too much of a problem, even though the average for this group (1982 dimensions) is 16,88 feet in length and 6.04 feet in width. The proportion of spaces to downsize in a given facility depends on the following factors: . Local zoning requirements or other regula- tions. · The type of customer the garage or lot will serve: . Employee/commuter facilities can usually pro- vide 50 to 75 percent of the total capacity as small spaces, especially if the downsized stall is 8 feet wide. If the width is 7.5 feet, the maximum number of small spaces should. be 50 percent, . Facilities serving the general public and/or shoppers should limit the proportion of small spaces to a range of 251040 percent of capac- ity with 8.0-foot stalls or 25 percent if the stall width is 7,5 feet wide, . Small stalls should have, a standard size with- in each parking facilily. whether the stan- dard is 7.5 or 8,0. or another dimension. Only that width along with the "full-size" auto di- mension should be used. Locating and Identifying Smaller Stalls In the location of smaller-car spaces. two points should be kept in mind: · Small-car spaces should be neither more nor less convenient than large-car spaces. · The parking layout should be easy to under- stand. That is, corn pact spaces should be well' marked and quickly distinguished from stan- dard spaces. Small-car spaces should not be "sprinkled" here and there in such a way that the custorner parking a large car is deceived by the size of an empty space, finding it too small for his use, Public acceptance of the small-car parking concept depends upon the customer being able to trust the size of a park- ing space. Small spaces may be located on either the right or the left side of an aisle. or an entire bay can be devoted to small spaces. The designer should strive for consistency in locating small spaces so that the repeat parker knows where to look. Two methods are commonly employed to iden- tify small stalls: . Signs only. . Color-coded stall lines, as well as signs, Many operators find that signs alone are ade- quate. It may also be useful to paint a line at the entry to the smaller stall, (This extra line would paral- lelthe aisle and mark the point beyond which the car should not extend.) The use of such addi- tional lines can also help educate customers in getting a "feel" for the size of their automobiles: if a car protrudes beyond the markings, it is not small. Even if a moderate amount of space misuse oc- curs-large cars using small spaces or vice ver- sa-it should not cause any real problems. Based on the growing number of small cars, the chances are slight that several full-size cars will arrive simultaneously and park in adjacent stalls. ~ '\ ---.

Parking layo..., efficiency depends on selection of stall arid parldng baydim~nsions that will provide a desired degree of service and economy while using a given site to its best advan- tage. The objective should be to maximize the number of vehicles that can be parked within a given area, subject to predetermined operational constraints, Ninety-degreeparking stalls with aisles parallel, to the long dimensions of the site, and &o-degree interlocking parking stalls with one-way aisles, usually require the least amount of space per stall. Angled parking stalls may provide greater ease in parking than 9O-degree stalls, and may derive some advantage in the fact that drivers are able to see and anticipate empty parking stalls more easily, Angle parking is often used where site dimensions will not allow sufficient parking bay width for 90-degree stalls. If adequate aisle width is provided, 9O-degree stalls can be as convenient and safe as angle parking. At parking angles of less than 9O-degrees, access aisles are normally one- way. Sometimes this is desirable; but one-way aisle systems may also cause drivers to travel further within the parking facility, increasing circulation time and the opportunity for conflict with pedestri- ans and other vehicles, The two-way aisles of a 9O-degree parking layout provide room to pass a standing or w.aiting vehicle. Other advantages o~ a two-way aisle system include better sight distance at aisle intersections and fewer aisles, hence shorter travel distance to locate an available park- ing space. Accommodating the Small Car The passenger automobile population in the United States is comprised of 55 pern,"! I~r;g'" r><< i}Pd 45 p~rcent small cars. However, with specific areas and generators, the vehicle size mix can vary dramatically from the 1980 nation!!l average, Some researchers predict by as early as 1985, small cars will represent 75 percent of the automobile popu- lation, From most estimates, it appears that the auto- mobile population will continue to increase but with a mix of predominantly small cars, approach- ing characteristics of the European auto population that is almost exclusively composed of small cars, EX<il:!ptions to~ trend can occur in locales where there is h av .Jse of6 ht trucks and/or recrea- Ilc)n,.1 vc.tu('IC1!I tc)r )C'rc,onitl tranS'),>rldl,u ..urrC.,I;- ), . thc' vc-hl( Ic' "11(1 rnl'l(tun~ (tin, Vitry gr~cHly between different types of generators, different communities. and different regions. There have been no comprehensive studies that indicate conclusively that parkers generated by medical or educational institutions drive small automobiles in greater proportions that other segments of the driving public, However, many in the parking indus- try tend to believe that work-trip commuters generally drive smaller cars, Alternative Approaches. Experience has shown local surveys provide the most reliable base for an assessment of small car usage, Continued demand for small cars may tend to equalize small car distri- butions between various locales and sections of the country. This emphasizes the importance of the local survey to determine automobile size distribu- tion and as a basis on which to justify requests for zoning variances concerning the size of stall that must be provided, In order to take advantage of the reduced park- ing area requirement for the smaller car, several approaches are available to the designer/develop- er, 1. The parking facility can be designed to provide a parking module that will park the larger cars in the existing vehicle population at an angle of 60 to 65 degrees. This layout will faci6tate conver- sion to 75 to 90 degree (using smaller parking stalls) small car parking in the future. 2, A new parking facility can be planned to incorporate two' different sizes of parking stalls catering respectively to large and small cars. (Some communities have zoning regulations that specify the maximum amount of small car stalls that can be provided,) 3, Or. the entire facility can be built with slightly reduced standards using only one stall size, Alternative #1 could be appropriate in situations where a fairly high proportion of full-size (large) cars must be accommodated today, In situations where it is known that the parking clientele will have a predominant number of small cars, consid- eration could be given to using two different size parking stalls as proposed in Alternative #2, Where a high proportion of the users will be commuting employees who tend to drive a higher proportion 47 ,-, of small cars and exhibit low parking turnover characteristics, providing up to half of the facility's parking capacity in small car stalls could be feasible, In comparison, facilities intended to serve high parking turnover should incorporate a lesser percent of small car stalls, if any at all, In all situations, the proportion of small car stalls that could be provided depends on the anticipated mix of small and large cars in the vehicle population as determined by available informa~ion for a particular site and generator type. Until small cars in use reach 70 to 75 percent of the total vehicle population, it will be most prudent to provide a lesser number of small car stalls than a survey might indicate as being possible, Again, this is particularly important when planning to use small car stalls in short-term, high-turnover parking situa- tions, As an alternative to a double standard for park- ing stall geometrics, one uniform, slightly smaller stall width could be used throughout a parking facility, as suggested in Alternative #3, The appro- priate stall size should be determined on the basis of the type of parker -Iong- or short-term - and other parking characteristics, as well as the degree of convenience to be provided to the parker. The New York and New Jersey Port Authority, for example, now uses an 8' 4" stall width throughout their parking systems, Even though this stall width is rather tight for the largest cars still found in the vehicle mix, the Port Authority's experience suggests that it is rare when two large cars are parked adjacent to each other and not separated by a small car. Thus there is usually adequate door-opening room for the large cars parked in the spaces. Special Operational Controls. If special size parking stalls are used in con junction with standard size stalls, the critical factor is to obtain full use of the two different stall types by vehicles of the size classification for which the stalls were designed. Two approaches to optimizing usage are possible, 1. Physically separate the small car stalls from parking areas containing large car stalls using lower parking fees and/or signing to attract small car use. 2. Integrate small car stalls within the same general parking area provided for large cars, and depend on .signing and restrictive geometrics to control voluntary use. The first approach is difficult to contr.ol and 48 ~. "'. .~ discouraged for the general public's use by at least two factors. First, a more complex set of parking rates would be necessary and the increments betw.l!,l!n, the rates. would probably be small. Secondly; fragmented parking areas would foster operating problems of revenue security and of diversion from' filled lot. sections. For institutional facilities, however, these objections can often be overcome, since institutions can be more dictatorial in directing staff, employees, and students in where to park, Also the collection of user fees may not present a problem. The second approach is more widely used, but requires several key features to help ensure effec- tive use of both small and large car stalls. The proper use of the small car stalls should be self- enforcing to avoid added operating costs and misuse that detracts from capacity gains or patron service, Small car stalls should be marked differ- ently from Ire car tails. A minimum of one foot in WI th is Sl1~gpdpd' that ic;if a laree (";If dall is 8.5' ~. . ..' . .,: ~ wide, then the small car s . in I . tudies have shown a substantially lower frequency of large cars in small car violations with 7.S1wide small car stalls than with 8,0' stalls for srriall cars. Also, the two different siz~ stalls should be marked differentlv: for f!xamplf!. whitf! ~f2.lr markin~s forlar~p car d;alle::ann )!'Qllnw for <:mall ~~ ~ Prominently posted signs and/or pavement markings are also necessary. Stall end lines, painted parallel to the aisle and connecting the two side lines of a small car stall are helpful in discouraging drivers of large cars from using the smaller parking stalls. Some parking facility operators have found that placing small car stalls in the most conveniently accessible areas of a parking facility assures that they fill and are totally utilized before small cars must begin parking in the larger stalls. However, this may also encourage large cars to attempt using the smaller spaces, Making both small and large car stalls equally convenient (in terms of walking distance) is still another approach, but diffi.cult to effect. Small car stalls should be located and sized (in terms of total arkin ca acit so that the a ways I beforethe entir in facilit. her- WI ,arge cars will be fortedtQ."usesmall car stalls.
