ADJOURNMENT: STAFF REPORT AGENDA 5. 1 TIGARD DESIGN REVIEW BOARD January 25 , 1977 - 5 : 30 P.M. Tigard City Hall 12420 S .W. Main Street - Tigard, Oregon DOCKET: SDR 2-77 REQUEST: A request for site plan and architectural review of a proposed 2, 000 sq. ft . undercoating facility . LOCATION: 15150 S .W. 72nd (Wash . Co . Tax Map 2S1 12D, Tax Lot 100) . APPLICANT: Terminal Service Company/Sabre Construction I . BASIC FACTS : 1 . The site is designated "General Industrial" on the Tigard Community Plan and zoned M-3, Light Industrial . 2 . 18 .58 .080(2) stated "A minimum of the front 20 feet shall be landscaped. " 3 . Outside storage is considered a conditional use "requiring sight-obscuring fencing and landscaping where necessary to reduce noise or glare or maintain the property in a character in keeping with the surrounding area . " II . FINDINGS : 1 . The applicant is requesting to build a 40 x 50 ' building to be used as an undercoating facility for Convoy Company . 2 . The site is bordered by S .W. 72nd on the west and I-5 on the east . 3 . S .W. 72nd is currently in deteriorating condition and in need of improvement. 4 . The site has two existing buildings and is completely paved to the fence lines . There is no landscaping on the site except for a partial row of arborvitae against the fence on S .W. 72nd. Because the 14 .5 acre lot is used as a distribution point for cars and trucks it presents an unsightly view from S .W. 72nd and I-5 . 5 . The site is on a slope making it difficult to screen effectively . In order for any impact to be made on the site large islands of evergreen plantings would be needed on the site as well as evergreen trees along the I-5 fence line. Site inspection has shown that it would be a major project to introduce island plantings that would have a good change of survival . However , it is feasible to screen the view from I-5 by evergreen trees along the fence . Because removing the concrete along `4�w' the fence would impose an undue hardship on the applicant , staff has contacted the Oregon State Highway Department , STAFF REPORT AGENDA 5 . 1 TIGARD DESIGN REVIEW BOARD January 25 , 1977 0W Page 2 which has verbally given their approval to a row of evergreen trees along their side of Convoy 's fence as an alternative if they can review the plans . 6 . The applicant is proposing to plant photinia along the S .W. 72nd fence line . Photinia is exceptionally hardy and superior to arborvitae in this type of situation. III . STAFF RECOMMENDATIONS : 1 . A non-remonstrance agreement for a local improvement district of S .W. 72nd be filed with the City Recorder . 2 . A row of evergreen trees (the type, size and location to be approved by staff) be planted along the east fence line . ;k RECOMMENDED STREET TREES ,,,,he following trees are satisfactory in most circumstances , however the list is not complete so other varieties and species will be considered.
