MEMORANDUM
. City of Sorin{!field
DATE: March 13, 2009
TO: Lissa Davis, Urban Planner
FROM: Clayton McEachern, Civil Engineer
SUBJECT: ZON2009-00009, Cobarubbia Vacant Lot at 59lh and Aster Development Issues
Meeting-Public Works Engineering Comments
The subject application involves a proposed Duplex or Triplex on an existing vacant lot. The
applicant has submitted prelinIinary plan documents for staff review.
Applicant's Questions Regarding Public Works:
1. What are the steps necessary to get the locally significant wetland classi~cation mapping
boundary error corrected to the edge (drip line) of the forested wetlands (4.3-177 BA.)?
The wetlands delineation may be appealed by obtaining a study, prepared by a licensed
professional acceptable to Oregon Department of State Lands, that shows a new boundary
and/or change of status from significant to insignificant. This study would be submitted to the
Oregon Department of State Lands.
This area is part of a contiguous forest area that provides drainage and stabilization for the slope
above.
2. What are the steps necessary to get a variance to the City ordinances that classifies some
wetlands as locally significant (4.3-177 B.1.a) that would allow the construction of triplex
to the wetland.
The change in status from significant to insignificant would require preparation and submittal of
documents per the Oregon Freshwater Wetlands Assessment methodology that shows this area
is not significant.
3. If a variance to the locally significant classification is not possible, will a variance to the
development setback (4.3 177 J.2) permit construction of a triplex?
If the variance were to be granted (by the planning department) it does not appear that the
maximum variance allowed would make construction of the triplex feasible.

4. If construction of a triplex is prohibited because of the area of impact, what variance, if
any, would be required to permit construction of a duplex.
Without a specific site plan it is difficult to give a specific answer on a conforming use or
building footprint. However, assuming such a variance is possible and granted, public works
would have the following concerns for any building constructed on a hydric soil:
A. Adequate drainage under the building be provided to maintain a healthy living
environment for the inhabitants .
B. The foundation be designed in such a way as to provide adequate support for the
building and any accessory structures
And, still assuming a variance is granted that allows for the desired construction, the lot would
require the following improvements:
The street would require 2/3 street improvements such as curb and gutter, sidewalk and possible
street lights. The site currently has a sewer line available in 59th St and a large (36") storm drain
crosses the site west to east that impacts ilic northern portion of the lot.
