A site Isoils investigation was performed on October 3,2000, at 33562 Osprey Drive. A copy of
the excavation and foundation requirements for Ambfeside Meadows Subdivision, 1 stAddition. was
made available and has been reviewed.
Approximately 24" of expansive clay material was encountered during the field inspection. The site
is to be excavated through the expansive material to the non-expansive decomposed ash or
sandstone material. The site cuts are to be sloped to a common low paint so water will not collect. )
underneath the proposed foundation. A maximum of 4" of crushed rock should be installed with
tracked excavation equipment to protect the site during inclimate weather. In areas where
additional crushed rock is required to attain grade the rock shall be placed with tracked excavation
equipment and compacted with a vibratory plate or roller,
The foundation drainage system per the City of Springfield's specifications are adequate for this
site and may be instal/ed later in the project without jeopardizing soil stability. No special footing
or stemwall reinforcement is required by site conditions 'on this project. Refer to the approved
construCtion documents not reviewed by Mortier Engineering for foundation reinforcement
placement.
On October 12. 2000. a compaction inspection was performed afterfiJl placement. The compacted
surface of the 3/4" minus crushed rock is adequate to support a conventional wood framed
residence with a standard foundation per the 2000 State of Oregon One and Two Family Dwelling
Specialty Code as adopted per the local jurisdiction, The compaction of the gravel surface is
greater than 95% of a standard proctor per A TM 0698-91. See attached data sheet.
