SUBJECT: "On Hold" Notice
Forest Terrace Subdivision and Lot Line Adjustment / LUA18-000124 and 125
Dear Ms. Halvorsen:
The Planning Division of the City of Renton accepted the above master application for review on
February 23, 2018. During our review, staff has determined that additional information is
necessary in order to proceed further, therefore the public hearing date tentatively scheduled
for April 17, 2018 is cancelled.
The following four items will need to be submitted before June 18, 2018 so that we may continue
the review of the above subject application:
1. As shown on the preliminary grading plan sheet 5 of 9, portions of the site contain
finished grades that would result in Protected Slopes. Pursuant to RMC 4-4-060M.2
and N.6, slopes created from cuts and fills shall not result in the creation of
permanent slopes 40-percent or greater which are 15-feet in height, i.e. protected
slopes. A revised grading plan that complies with these grading regulations will be
required.
2. The grading plan and site sections sheet 6 of 9 identify the stormwater vault
containing an exposed face of up to 8-feet in height. The applicant will need to
reduce above-grade vault exposure to 6-feet and lower. Additionally, aesthetic
treatment of the exposed face and ground level landscaping will be required.
3. The modified minor arterial street section along Union Ave NE will require a
modification application. The modified minor arterial standard would require a right
of way width of 81’. The paved roadway width required would be 44’ consisting of
2 – 11’ travel lanes, 1 – 12’ travel lane, and 2 – 5’ bike lanes. A 0.5’ curb, 8’ planter,
8’ sidewalk, and 2’ clear at the back of sidewalk are required along each side of the
roadway. A right of way dedication of approximately 10.5’ along the Union Avenue
NE frontage will be required to provide a half street right of way width of 40.5’. The
application form can be found on the City’s CED Forms page by searching for “City
Documents” in the search bar on the City of Renton website. The modification fee
is $262.50.
4. The minimum Horizontal separation between the water line and the 2 storm lines
shall be 10 feet. Please relocate the storm lines to provide the 10-foot separation.
The City will accept a minimum of 7.5 feet of horizontal separation between the
water line and the storm line (outside wall to outside wall) if a city approved
restrained joint pipe system and fittings are provided for the water line in addition
to concrete blocking at the fittings.
The following two items below are advisory and will need attention during the construction
permitting stage of the proposal:
1. The street and water/sewer mains need to be extended to the west edge of the
property line. A blow-off assembly shall be required at the end cap for the water
main and manhole for the sewer main will need to be located within a paved
surface.
2. There is an existing 12” ductile iron dead end water main east of the site in Union
Avenue NE that can deliver a maximum flowrate of 1,240 gallons per minute
(gpm). Reference Project File WTR2702847 in COR Maps for record drawings. The
flow restriction is due to a 300’ section of 8” water main in Union Avenue NE from
NE 25th Street to the north property line of Sierra Heights Elementary School. If
this 300’ section of 8” pipe is replaced with a new 12” pipe, the flowrate of the
existing 12” main in Union Avenue NE from of the development will increase to
approximately 3,000 gpm. The maximum flow rate of the internal water main will
be limited to 1,240 gpm unless the 300’ section of 8” pipe in Union Avenue NE is
replaced with a 12” main as indicated above. Residential buildings that have over
3,600 square feet of gross building areas may have fire flow demand of 1,500 gpm
or more. Please verify with the Renton Regional Fire Authority to determine the
preliminary fire flow demand and size the water main(s) accordingly to provide
adequate flow to the new hydrants.
At this time, your project has been placed “on hold” pending receipt of the requested information.
The City will reschedule the Environmental Review Committee meeting and public hearing upon
accepted resubmittal of above-referenced items. Please contact me at (425) 430-6593 or
mherrera@rentonwa.gov should you have any questions.
Sincerely,
Matt Herrera, AICP
