The design of Phase I will provide adequate circulation for both automobiles and pedestrians. Each townhouse unit contains an attached 2 -car garage. There is no space designed as part of Phase I to include guest parking; all guest parking is included as part of Phase IL There is no parking allowed in the shared garage access area to maintain garage access for residents, and there is no on- street parking allowed on the 20 -foot wide private street serving Phase I of Osterly Park Townhomes or the public right -of -way of S. 144 Street. In order to maintain adequate vehicle circulation and emergency vehicle access, staff recommends a condition of approval to require a minimum of two guest parking spaces be added to Phase L These spaces can be added to the south side of the site, and shall be removed at such time as the private access drive is extended as part of Phase IL The addition of the guest parking spaces and the rear yard landscaping may require revisions to the lot or tract layout as shown in the preliminary subdivision survey. Staff recommends the design of these spaces and any necessary changes to the survey be reviewed as part of the Public Works constriction permit for Phase I. Plans have been reviewed by the Public Works, Fire, Building, and Planning departments to ensure adequate utilities are included to serve the development proposed as part of Phase I. Sewer, water, and storm drainage infrastructure is adequate to serve Phase I, and is designed so that it can be extended into Phase II of the project. An original condition of approval of the preliminary subdivision was: `Buildings will be required to meet fire flow requirements per the International Fire Code." The previous subdivision approval required that the water line be looped from the main located off 34 Ave S. Per the applicant, installation of the looped water line as part of Phase I will be prohibitively expensive. The Fire and Public Works Departments requested the applicant obtain a written statement from Water District 125 to ensure that the design of the water line proposed for Phase I will meet adequate fire flow requirements for the sprinklered townhome units. Attachment B is a letter from Mark Parsons of Water District 125, which states there is adequate fire flow for the first 8 units without a looped water line; Phase II of the project will require the water line to be looped, consistent with the originally approved utility design. 5. All phases shall be recorded irithiii the fire -near life of the preliinhiar plat, wiles all exterisiori iN granted. Constriction of Phase I is expected to commence in Spring /Summer of 2012. All phases shall be recorded within five years unless the applicant applies and receives approval for an extension. CONCLUSIONS PHASING PLAN 1. The phasing plan includes all land for the entire development project to constrict 31 townhomes, with associated recreation space, access, utilities, landscaping, and frontage improvements along 34 Ave S. In case Phase II does not occur, staff recommends a condition of approval to require legal access to the remaining area of tax parcel 004000 -0094 be provided through an easement, or alternatively, by combining the remaining area of tax parcel 004000 -0094 with tax parcel 004000- JR Page 1s of IS 03 1x'2012 H: Design Review Osterh- Townhomes Major Modification_L12 -005 PL12 -1111 1_12 -005 LOS- 1179_PL12 -1111 Osterh- Major Modification SRdoc 21
