It is our opinion that the future expansion of the Village Green Retirement Campus, as currently proposed, will have a parking supply sufficient to meet the future peak parking demand of the campus. Included within this letter is our understanding of your development plans; a summary of your existing on -campus parking supply and demand, a forecast for your future on -campus parking demand, and our conclusions - PROPOSED CAMPUS EXPANSION Village Green Retirement Campus is located at 35419 1' Avenue South. Federal Way, Washington. Attachment A includes a vicinity map highlighting the campus location. A site layout illustrating the existing and proposed locations of the senior living units are included in Attachment B. The campus has two accesses. a primary access off 1" Avenue S and a secondary access off SW 350' Street. Village Green Retirement Campus has been in operation since 1997 and the existing campus includes a total of 153 residences comprised of 85 independent living apartments, 52 assisted living apartments, and 16 cottages/ duplexes. Currently 87-percent of the available dwelling units are occupied. The site includes a mix of one and two bedroom units. Residents are not restricted from having their own vehicle on -site. Village Green Retirement Campus has received land use approvals to expand their site to include Phase 11, composed of 165 independent and assisted living apartments, and Phase I[[, composed of 40 cottages/ duplexes. Phase III, also known as Cottages West and referenced as such in Attachment B. is currently under construction and is proposed to be complete in 2009. During construction, construction vehicles have been directed to only use the SW 356`h Street/ 2"d Avenue SW site access. It is our understanding that Village Green Retirement Campus has currently entered into a Process IV review with the City of Federal Way to extend the land use approvals granted in the hearing examiner decision dated April 23, 2002 for the development of Cottages West d Villa a Green Phase U. RECEIVED NOV CITY QFWE i Ay foF +( TS1 Transportation Solutions, Inc. Ms. Heidi Swartz November 5, 2008 Page 2 of 3 For this evaluation, the cottages/ duplexes of Cottages I (see Attachment B) will not be included in the evaluation of the future parking conditions of the future site. Each residence of Cottages I includes a one or two car garage with available parking space on each unit's drive apron. The cottages/ duplexes will have enough space on their lots to provide parking for their residents and accommodate daily visitors as well - EXISTING ON -CAMPUS PARKING TSI confirmed that the existing campus includes 103 total parking spaces as shown in Attachment C. Between 11:00 AM and 2:00 PM from Wednesday, October 1, to Friday, October 3, TSI documented the existing peak hour parking demand at the existing Village Green Campus. This time period was identified by Village Green staff as the typical peak observed parking period at the existing campus. TSI confirmed the three hour peak period based on the existing program schedule. The following table summarizes the results of the existing peak parking demand study, which is included as Attachment D. EXISTING ON -CAMPUS PARKING SUPPLY AND PEAK PARKING DEMAND Start Parking Sugly Peak Parking Demand Time ACC. Non-Acc. Total Acc.' Non-Acc Total 11:00 AM 11 92 103 8 71 79 12:00 PM 11 92 103 7 65 72 1:00 PM 11 92 103 7 62 69 1. Does not include the available parking supply associated with Cottages. 2 Accessible parking spaces supplied or occupied 3. Non -accessible parking spaces supplied or occupied Based on the existing on -campus parking supply, the peak hour parking demand occurs between 11:00 AM and 12:00 PM with 77-percent of the on -campus parking spaces occupied. As stated previously, 87-percent of the existing on -campus units, excluding those associated with the Cottages I, are occupied by residents. Thus, the peak parking demand ratio of on -campus parked vehicles to the number of occupied residential units, excluding the cottages/ duplexes, is 0.66 (peak parking demand of 79 vehicles - 119 existing occupied units). This parking ratio accounts fort ose residents, visitors, and staff who are parked on the retirement campus. FUTURE ON -CAMPUS PARKING Similar to the existing conditions, the parking area for the resident and visitor vehicles associated with the 40 cottage/ duplex units of Cottages West are assumed to be adequately accommodated by the garages and drive aprons of each cottage/ duplex_ Thus, only the 165 independent and assisted living apartments associated with Village Green Phase If factor into forecasts of parking demand at the future campus. The existing peak parking demand ratio of on -campus parked vehicles to the number of occupied residential units, excluding Cottages West, was applied to the total amount of senior residential units of the future Village Green Retirement Campus to forecast the site's future peak hour parking demand. There are 302 total units associated with senior residences of the existing campus and Village Green Phase [I. It is assumed that all of the 302 units will be occupied in the future with the EXIIT S PAGE&--N� TS1 Transportation Solutions, Inc. Ms_ Heidi Swartz November 5, 2008 Page 3 of 3 proposed site expansion. Applying the 0.66 ratio of parked vehicles to occupied units to the 302 future occupied units results in the peak parking demand of 200 vehicles for the future site. It is understood that currently there are 120 parking spaces proposed to be added to the development site. The current locations of the additional parking spaces are illustrated in Attachment E_ The total amount of parking currently proposed for the future Village Green Retirement Campus is 223 parking spaces. CONCLUSIONS The following primary conclusions can be drawn from this letter: • The existing Village Green Retirement Campus includes 153 total units comprised of 85 independent living apartments, 52 assisted living apartments, and 16 cottages/ duplexes. The parking associated with the existing cottages/ duplexes can be accommodated at each cottage/ duplex lot_ • Of the existing independent living and assisted living apartments, 87-percent are occupied and there are 103 marked vehicles parking spaces serving the existing site's residents, visitors, and staff_ • The peak parking demand ratio for the existing campus is 0.66 vehicles per occupied dwelling unit. • The proposed campus expansion includes the addition of 165 independent and assisted living apartments (Phase II) and 40 cottage/ duplex units (Phase [IV Cottages West). The parking associated with the new cottages/ duplexes can be accommodated on each cottage/ duplex lot. • The proposed campus is forecast to generate a peak parking demand of approximately 200 vehicles. This is based on the peak parking ratio (0.66 vehicles per occupied dwelling unit) multiplied by the total number of independent living and assisted living apartments (302 units). It is TSI's opinion that when Village Green Retirement Campus Phase II and Phase III are fully developed, the future on -campus parking supply of 223 parking spaces will accommodate the campus' future peak parking demand, 200 vehicles. We trust that the information presented within this letter will assist you in your future decisions, regarding parking, at the future Village Green Retirement Campus_ Should you have any questions please feel free to contact us at your convenience.
