We have inspected the above sites and have found the soils are clayey with several seeps under the proposed house location. To prepare the site for construction, and to protect the house from soil-induced stress, we recommend the following: . 1, Existing seeps are trenched to drain on the downhill side of the house pad site, The trenches should be fonned in a wide "V" approximately 18" deep at the base and 48" wide at the top, They should slope to drain at not less than 2% (1'/4" per ft.) 2, The trenches should be backfilled, and the entire pad site filJed to a depth of 12", using . 3/4" -(0) or 1" -(0) crushed quarry rock. 3. The entire pad should then be rolled, using a fully-loaded rock truck or 12-ton rated roller compactor, making multiple passes until maximum consolidation is reached. 4. A proofing roll will be obselVed by a representative of the engineer's office, and an inspection report will be sent to the City. 5. The perimeter foundations shall be reinforced accOrding to the attached drawing, The garage floor slab shall be reinforced using #4 bars at 24" o,c. each way, at mid depth of slab. The reinforcing shall be tied in place, using "dobies" or other means of ensuring proper placement. 6, . The floor system using post-and-beam should be changed to a joist system with strip footings, or the piers for the post-and-beam be installed as 8" x 12" strip footings, with (1) #4 bar at the centerline of the footing. This will control differential movement in the floor system, ~ '-. TRANSPORTATION CIVIL SURVEYiNG ./ ~~ TI ~-.---j _~~~I , l-'-~':~~'.J' .r;- ~. 4.4 I ", :. ".' .", .......~. ~ 4" .'. "'..' '..

'7-471 ($03) 7.'.06$7 SHEET OF TOTAL P, 83 .' . . 1 MEMORANDUM August 27. 1993 TO: Building Division FROM: Planning Division, Mel Oberst RE: Building Permits for Lots 137, 138 and 139 McKenzie Hills First Add Glen Kotara These lots are in the Hillside Development Overlay District. Pursuant to Section 26,080(1) front. side and rear yard setbacks may be reduced (to zero if necessary) in order to retain trees, protect natural features and minimize activities that adversely affect scenic qualities, slope and soil stability and drainageways. The reductions in setbacks for these lots has been approved by the Director to preserve exiting trees and minimize cuts in the hillside. Dwelling and garage setbacks may be adjusted to avoid uncessary excavation or tree removal. Glen Kotara has submitted survey drawings of the lots and the setbacks needed to achieve the goals of protecting the landscape. If you have any questions please contact me.
