3107 Oakes Avenue,Short Plat,Fill Grade,Height variance
Dear Mr.Johnston
We appreciated meeting with you on 12-20-05 and subsequent occasions to discuss the above
referenced application. What began in mid November 05 as a building height variance has since
expanded. As you are aware this site,located in the NE quadrant of Georgia and Oakes Avenue,is
in a depression and has experienced flooding on at least 2 occasions in the past.The flooding on
both occasions was severe enough to disrupt traffic on Oakes Avenue for prolonged periods of
time.Based on those present at the time it appears the runoff came from the Cranberry Lake area.
From the DRG and associated site visits came the following points:
❑ Your proposal includes filling the depression to accommodate 2 building sites,which
would be accessed from the unopened alley way bordering the south line of the parcel.
❑ The site is bordered on the south by relatively steep banks approximately 30 feet high.
❑ To avert future storm drainage runoff from entering the site you have recommended
constructing street improvements in the form of curb gutter,sidewalk and storm drainage
along the frontages of Oakes,Georgia and W 2nd.
❑ You have submitted a critical area report in January of 2006.The report did not identify the
presence of wetlands.
Staff has the following recommended conditions:
I. It is imperative that the WSDOT culvert,crossing Oakes be maintained,your
proposal must include measures to maintain this conveyance system.
2. The depression extends to the south of the site considered in this application.As a
result the fill material associated with this development cannot extend south of the
alley way without the consent of the adjoining owner[s].
3. A slope stability and hydro-geology report must be submitted by a geo-technical
engineer addressing the drainage/slope concerns.The report must specifically
address the effects of a catastrophic failure of the Cranberry Lake system.Based on
this report staff will evaluate the merits of the suggested street improvements
related to drainage.
4. Issues related to emergency services access and other municipal services will be
addressed during civil plan review.
Please contact us at your earliest convenience, if you have any questions.
