Bused on actual need determined by rational analysis and calculation, we have found the project space demand to be as follows: Phase 1 1 & 11 I - 111 L - lV This actual need determined by rational analysis and calculation is pre- dicated upon maximum occupancy of restaurants, meeting rooms, and ball- rooms at the same time as the office building, commercial and retail areas are undergoing maximum usage. Maximum occupancy is anticipated to occur three to five days a year with the "probable maximum occupancy" (with 150 unoccupied stalls at peak hour) occurring five to ten days a year. The following report outlines your needs for the contemplated phases of development. Please call if you have any questions. Sincerely, RICHARD F. ROTI S ASSOCIATES, INC. Richard F.

The information would be compiled to allow a compre- hensive and planned program for parking requirements to satis- fy the needs of the people who shop, work, conduct business and seek entertainment in the area. Floor areas were gathered to determine projected parking needs for the proposed phased development. Based upon these needs balanced supply /demand locations were determined and provided in the Architect's layouts. METHODOLOGY Most zoning ordinances relate peak parking accumulation and to- tal daily parkers with gross floor area. This study and subse- quent recommendations are based on a calculated demand taking into consideration that unit factors decrease as project size and multi -land use increases. The parking demand generated was derived by applying generation factors to proposed floor areas. The parking generation factors used are those which have been determined in similar develop- ments. Adjustments were made for on -site business generation and persons /vehicle for various land uses. The parking space demand for each land use in each phase of development was calculated on the basis of floor area, excepting public assembly area which is based on persons utilizing given • areas, using the parking generation factors shown in Table 11 . The application of these factors to the various buildings and areas of the proposed project results in a total demand for parking spaces regardless of time of day. Tabulation of this data in Table V indicating parking space demand by hour of day results in a peak hour demand while simultaneously showing space utilization. Thus, the parking space demand analysis is based upon that,. demand which is created during the peak period of an average weekday, or restated, it is the. maximum peak accumulation of parked vehicles on the maximum demand weekday. • N m tn 200' 790.82' RELOCATED PARKING STRUCTURE n SERVICE STATION 1 50' 949.43' SOUTHCENTER PARKWAY P H A S E I, II & III S I T E P.L A N No Scale • FIGURE 1 0 302.38' NORTH 302.42' 50' 200' RELOCATED in SERVICE' STATION The planned development listed in Table I is illus- trated in Figures 1 and 2.

The development will contain a mix of retail and commercial space as listed in Table 1 . Floor area and land use data contained in this report were obtained from Burke, Kober, Nicholais, :Archuleta, Architects, Los Angeles, California. The complex will contain, as major generators of parking demand, an office building with banking and brokerage tenants, retail areas and to a lesser extent, a 308 room hotel with ancillary activities. PARKING DEMAND Parking needs depend on type and intensity of land use and the social and economic characteristics of the land users. Existing and planned travel modes affect, or will affect parking needs. Where the automobile is the dominant mode of tra- vel, parking demand reaches maximum peaks in rela- tionship to per capita auto ownership. Automobile ownership in the state of Washington, as an example, increased by 6.9% in 1972 over 1971, as compared to a national average increase of 3.9 %. This trend, primarily the result of expanding population and multiple car ownership, is expected to continue in the years ahead. Under such conditions, where inad- equate or minimum public transportation exists or customer acceptance of same is limited, adequate parking inventories are essential to the success of a commercial center founded and based on commerce. Good public transportation can reduce parking require- ments by as much as 10 percent. Hotel parking demands are dictated by proximity to "airport and rental car station, determining the customer drive -in /fly-in ratio, and the nature of hotel, i.e., the number and size of ancillary func- tions.

A pre- ponderance of customers on multiple purpose trips and office employees result in lower than normal park- ing requirements. Restaurants and theatres in commercial centers need little daytime parking and utilize vacant spaces during evening off - peaks, when other commercial devel- - opments are closed. PARKING DEMAND FACTORS The parking demand generated by each land use was derived by applying generation factors to the classi- fied floor area tabulations. The parking generation factors used were those which have been determined in similar metropolitan areas in the western U.S. Ad- justments were made as a result of information gained from City agencies and observations. From the infor- mation thus obtained, final minor adjustments were . made to some of the factors and a master list of short term and long term parking generation factors was produced. Using these factors, parking space demand was calculated for the subject Maguire Partnership Development, using floor areas as a basis for parking generation. The projected parking space demand for each land use within the project area was calculated using the parking generation factors shown in Table 1I . The application of these factors to the various land use categories results in a total demand for parking space. If this parking demand exceeds the total avail- able supply of parking spaces, then it is this excess that determines the need for additional parking faci- lities. a.

Four (4) percent public transit reduction incorporated for this project. c. Hotel ratios vary considerably based on drive -in /fly -in or walk -in type. Assumptions for Tukwila, Washington hotel are for drive -in domination. Thus 10% reduction allowed based on 10% fly -in combined with primarily night hour operation for high demand calculations. Average demand is predicated upon 70% drive -in and 40% for low parking demand. d. Some danger exists in utilizing studies older than two years in view of rising per capita auto ownership. Referenced values have been adjusted to account for the state of Washington in- crease per Department of Transportation, Federal Highway Administration 1972 auto registration report.

General office calculated parking demand at 3.5 spaces /1000 s.f. G.F.A.; 8% short term, 92% long term with 15% oversell on long term spaces requires 553 long term spaces and 57 short term spaces for a total of 610 spaces. Banking and Financial: 18,900 s.f. of financial and miscellaneous lease area is provided in conjunction with the office building. By practical demand and rational analysis, the bank area of 6500 s.f. will experience 50% walk -in and 50% drive -in traffic due to on -site generation. The norm of 7.0 spaces /1000 s.f. of floor area is thus reduced to 4.5 spaces /1000 s.f. of floor area requiring twenty -nine spaces. Other financial consisting of 6400 s.f. experiencing same demand and generation also requires twenty-nine spaces. Core commercial and lease area around motor court are contemplated as small shops, travel, etc. Travel area (1600 s.f.) at 2.5 spaces/ 1000 s.f. of floor area requires four spaces. Adjustment for on -site generation reduces requirement below actual need. Two employee plus one visitor space is considered minimum. The balance - 4400 s.f..of core commercial classified as potential bank area at 4.5 spaces /1000 s.f. requires twenty spaces. PHASE II PARKING DEMAND Other Commercial: Intended use of 12,7 s.f. commercial area at 3.5 spaces /1000 s.f. G.F.A. with 30% on-site and 70% drive -in genera- tion requires 31 spaces. - Retail: The proposed 75,000 s.f. of retail space will encounter a reduced parking demand due to multiple purpose trips and generation from the adjacent commercial and hotel facilities. Actual need of 5.0 spaces /1000 s.f. with 73% drive-in and 27% on -site daytime • generation requires 273 spaces. Restaurants: Three restaurants at 5,000 s.f. each, 70% efficiency, at 1 /person /25 s.f. = 840 persons. Parking demand calculated at 60% walk- in /40% drive- inlfor luncheon crowd at 1.65 persons /car 'requires 102 spaces. Dinner trade 90% drive- in /10% walk-in with 2.653 persons /car requires 143 spaces. Source: Valet Parking Company. Theatre: 1100 seats, of primarily night -time generation, with 10% walk -in and maximum vehicle occupancy of 2.9 persons /car requires 341 spaces for 100% demand. Commercial: At 3.5/1000 s.f. G.F.A., with 30% on-site and 70% drive - in generation calculated demand is twenty -five spaces for Health Club type operation. PHASE tit PARKING DEMAND Commercial: 2100 s.f. calculated for practical demand as per previous commercial area requires 5.145 spaces. Hotel: In terms of parking demand, the third most significant faci- lity within the proposed development will be the hotel. The propor- tioning of drive -in /walk -in clientele is a determining factor in the amount of parking space required. Since motor hotels cater to the driving public and usually offer free parking, they exhibit a high ratio of cars to rooms. Conversely, a facility such'as the Washington Plaza Tower in Seattle, located in the business district, is more attractive to the non-driving business man. A high drive -in demand of 85% of total rooms combined with a room demand of 1.7 rooms per car results in a peak hour space demand of 150 spaces. Ballroom: 500 seats. Luncheon - 80% drive -in at 2.2 persons/ vehicle (182). Dinner - 95% drive-in at 2.85 persons /vehicle (167). Coffee Shop: 110 seats. Breakfast - 20% drive-in at 1.5 persons/ vehicle; lunch - 40% drive -in at 2.2 persons /vehicle; evening - 50% drive -in at 2.2 persons /vehicle. Cocktail Lounge: 125 seats. 20% drive -in at 1.8 persons /vehicle. Specialty Restaurant: 180 seats. Lunch - 50% drive-in at 2.2 persons/ vehicle; dinner - 80% drive -in at 2.65 persons /vehicle. Dining Room: 150 seats. Lunch - 50% drive -in at 2.2 persons /vehicle; dinner - 60% drive -in at 2.65 persons /vehicle. Meeting Rooms: 4000s.f. 90% efficiency, 1 person /25 s.f., 85% drive -in, 1.65 persons /vehicle at luncheon, 2.4 persons /vehicle in evening, requires 102 spaces at maximum occupancy. The "pro- bable maximum occupancy" can be expected to be 82 space demand (80 %) and "high normal occupancy" to be 51 spaces (50 %). PHASE IV PARKING DEMAND Office Buildings: Two towers of 200,000 G.F.A. each @ 3.5 spaces/. 1000 G.F.A. each; 8% short term parkers and 92% long term with fifteen percent oversell on long term requires the following: 200,000 G.F.A. @ 3.5 700 spaces less short term spaces 56 644 less 15% oversell 747 Add short term spaces + 56 603 x 2 towers Spaces Required 1206 spaces Retail: 30,000 s.f. retail area @'5.5 spaces /1000 s.f. with 75% drive -in and 25% on -site generation requires 116 spaces. Ice rink: Little data exists for ice rink parking requirements. A :survey of needs with Ice Capades established demand figures aho:m in Table V.

The most common approach is to achieve design efficiency by tandem parking and inclusion of compact and sub - standard stalls. This procedure attempts to follow the principle that parking space design efficiency is achieved by utilizing the lowest number of square feet per stall possible while maintaining acceptable parking flow and operational characteristics. Since parking facilities are purchased in terms of square feet per stall, the lowest cost per stall is theoretically obtained with the design requiring the least number of square feet per stall. The number of square feet per stall - generally a product of city code requirements has historically been greater in suburban and rural areas than in urban centers. Low demand for land encourages excessive use of space for parking purposes. On the other hand scarcity and high cost of land for parking creates pressures dictating more efficient area usage. High construction costs for subterranean or elevated parking facilities encourages attempts to achieve higher degrees of design efficiency. Most city parking requirements were established during periods of low motor vehicle density, on a non - technical base, and are wasteful of space. There is, however, a growing awareness that optimum space usage, with proper parking (self-park) and vehi- cular flow, can be achieved, through establishment of practical parking design standards. The move toward realistic land and structure space utilization for passenger car parking was ini- tiated by the City of Los Angeles in February, 1972 following .publication of "A Parking Standards Report" in 1971. THE PARKING STALL The width of parking stall is the principal factor involved in parking design. Two considerations are involved - the door opening dimension (level of convenience) and the frequency of door movements. In this manner the width of stall is predicated upon the convenience provided, the user of the stall and consi- deration.for the frequency of stall turnover. Using a uniform bay dimension of 55.40''and adjusting staZZ width to accommodate the specific type of user, i.e., the short or Zong -term parker, efficient Land and improvement usage is achieved. Parking stalls with high turnover, i.e., for shoppers, banking patrons and other uses with a high frequency of door opening movements, require wider than average stall widths. Parking spaces with low turnover, the all -day parker for example, where the door openings generally occur once in the morning and once again in the evening, can be relegated to minimum or near minimum stall widths. Recommendations for practical stall width levels of convenience follow: TABLE VI A full size vehicle at the maximum width of 80" parked in a 9'-0" stall allows 28" clearance for the door opening movement. Subtracting the door thickness of 5}" results in 22/" for the parking patron movement. An 8'-8" stall allows 24" for the parking patron to enter or leave the car. These clearances are predicated upon two full size vehicles parked in adjacent stalls. Seldom is this the case. The natural averaging system occurring with sub - compacts, compacts, intermediates, standard and luxury cars will invariably allow greater door opening dimension than full size car design calculations indicate. With properly dimensioned parking bay (4-2) the most favorable self -park design efficiency is achieved in the 50 - 70 degree angle of park range. 12 Minimum Comfortable Generous Extravagant Attendant Park 8' -0" Self -park - long term 8' -0" 8' -4" 8' -6" 8' -8" Self -park - short term 8' -4" _ 8' -8" 9' -0" Over 9' -0" Compact stalls 7'-4" 7' -6" 7' -9" 8' -O" PARKING DESIGN STANDARDS Increasing land values and construction costs in recent years have emphasized the need for efficient parking solutions.

FIGURE 5 8' -6" LONG -TERM STALLS The Consultants Outlook PROPOSED PARKING STANDARDS FIGURE 6 8' -8" SHORT -TERM STALLS Parking Consultants and published data have varied widely in opinions as to what stall, aisle'and bay dimensions constitute reasonable and workable design standards, particularly prior to 1970. The majority have, in recent years, evolved to standards patterned by George Devlin of National Garages by employing efficient design standards. Today, Devlin and Rich out of De- troit, Walker from Kalamazoo, Young in Dallas, Boldon, Lins- cott and Roti on the West Coast and other consultants across, the country vary only slightly from each other. Others, how- ever, maintain comfortable parking can be achieved only with much greater dimensions. The fact remains that recovery of parking investments are most frequently subsidized by the generator it serves. Design eff- iciency becomes paramount and is accomplished thru use of eff- icient design standards. 4 ^ -, ". , �.• u. 64 63 62 61 60 59 58 57 w 5 5 5 I- 5 • 5 3 51 a 50 m • CD 49 . d 48 47 46 45 44 43 42 41 40 El Segued** + 30 32} 35 37f 40 42+ 45 47f 50 52f 55 57} 60 62} 65 67k 70 72} 75 77+ 80 82} 85 87+ 90 PARKING ANGLE DEGREES FIGURE 7 dards RICHARD F.

There is, however, a grow- ing awareness amongst municipalities and the private sector that optimum land and improve- ment usage can be obtained with realistic parking standards based on type of parking stall user (i.e., short or long term parker), the level of convenience provided the parking patron and the ratio of small to full size cars currently in use and projected for the near future. Optimum design standards are seldom encoun- tered amongst City standards. Santa Monica, Burbank and Santa Barbara on the West Coast, are several cities with realistic approaches to land and improvement investments. Other cities, through recognition of short and long term parking usage, have adopted dual stall width standards, i.e., a narrower stall width requirement for the long -term parker. Small car production, sales and registrations are also increasingly being recognized by many cities in code changes. Illustrated in Figure "A" is the 8' -6" Parking Design Standards long -term design curve related to City of Pasadena long-term parking standards. Note that parking bay requirements, i.e., wall-to -wall dimensions, for the City standards are excessive by approximately 3'-0" for 45° angle of park, 4' -4" for 60 3'-0" for 70 and no penalty .for 90° angle of park. in such cases, City Standards encourage use of 90° angle of park, whereas, proper design standards would result in preferred angle park facilities in the 50 - 70 degree range at no premium to parking investments. 1.

Reporting to Automotive News, an automotive trade jour- nal, Brooks claimed the Wankel will boom the small -car market for the same reasons that the smooth and powerful V -8 caused the larger -car market to reach sales heights. "Largely for lack of a suitable engine, many small cars made by Crosley, Hudson, Kaiser, Nash, Studebaker and Willys faded away in this country," Brooks said. "The original Falcon -Chevy II- Valiant small cars introduced in 1960 -62 have also faded away as they were replaced with cars a size larger so that the superior V -8 engines - demanded by the public could be squeezed under the hood." Brooks noted that the small Corvair died for reasons other than normal market forces. "The Vega and Pinto are the latest iri the long history of attempts by U.S. auto makers to satisfy the small - car market. But the consumer tolerates, at best, the roughness and poor performance of these four - cylinder cars in exchange for much lower prices." This has meant reduced profits to the " February " Automotive News 2/5/73
