CONSTRUCTION MITIGATION DESCRIPTION
FOR
SUMPTER SHORT PLAT
BCE Job No. 20291
The proposed short plat of the Sumpter Property will involve clearing and grading for the construction of
lots, new road improvements, installation of utilities, and other land disturbance activities. The following is
a summary of how these activities are expected to be carried out and managed to minimize impacts and
comply with applicable rules and regulations during this phase of the project:
· Anticipated Construction Schedule: Clearing and grading is likely to begin in 2019 assuming the
entitlements and permits are approved. The bulk of the work should be completed in 2019. Based
on this schedule, we expect that the plat could be ready for recording in late 2019 with home
building to commence after the plat is recorded based on market conditions. Model home
construction may commence prior to recording as allowed by the City of Renton.
· Hours and Days of Operation: The typical hours of operation for construction will be from 7 a.m.
to 6 p.m. during the winter months. During the summer months, construction will begin at 7 a.m.
and may extend to 7 p.m. (pending approval from the City of Renton). The typical work week will
be Monday through Friday. Construction work may also take place on Saturday, as normally
allowed by the City of Renton, especially during the dry season (April to October) in order to
expedite completion of the project during the dry season.
· Proposed Hauling/Transportation Routes: The haul route for importing or exporting materials to
and from the site will be determined after coordination with the City of Renton Inspector prior to the
start of construction. The haul route may include 156th Avenue S.E. to N.E. 4th Street and/or S.E.
142nd Place to SR-169 as determined by materials.
· Measures to be Implemented to Minimize Dust, Traffic and Transportation Impacts, Erosion,
Mud, Noise, and other Noxious Characteristics: All temporary erosion and sedimentation control
measures required by the City of Renton and other agencies will be implemented and maintained
(e.g., rock construction entrance, silt fencing, temporary sediment pond, straw mulching and hydro
seeding). Also, as required by DOE, a Certified Erosion Control Lead will be assigned to the project
and all erosion BMPs will be implemented and maintained as required by the NPDES Permit for
the duration of the project. Watering will be implemented, as necessary, to control dust during the
summer months and all construction equipment will be equipped with appropriate mufflers to
comply with local noise ordinances.
· Any Special Hours Proposed for Construction or Hauling (i.e., weekends, late nights): If it is
determined that additional hours are needed to complete the construction, the contractor will
coordinate with the City of Renton to obtain approval for such extended hours.
· Preliminary Traffic Control Plan: A Preliminary Traffic Control Plan has not been prepared at this
time. Once the haul route(s) has(have) been approved by the City Public Works Department, a
traffic control plan will be prepared in accordance with the City Road Standards and WSDOT
guidelines for the frontage improvement work within the 156th Avenue S.E. right-of-way. Frontage
improvements will be limited to constructing curb, gutter, planter, and sidewalk along 156th Avenue
S.E. where shoulder closures will be implemented.
