Construction Mitigation Description
The following narrative is provided to describe the proposed construction mitigation
measures that Harbour Homes, LLC “Harbour Homes” and the to be named general contractor
“Contractor” for The Pines will implement throughout the duration of the site development and
infrastructure period as well as during building construction.
Proposed Construction Dates (Site Work): February 2020-February 2021
Harbour Homes anticipates on beginning clearing and site development work in the early spring
of 2020 depending on the timing of approvals. Harbour Homes anticipates roughly a 180 day
schedule to finalize all grading, storm, sewer, water and first lift of asphalt on the site. The goal
will be to have the site completely stabilized by August 1st, 2020 before the fall.
Proposed Construction Dates (Building Construction):
Harbour Homes plans on beginning construction of a model home in January of 2021 and
anticipates starting two homes per month thereafter with an average construction timeline of
seven months to complete.
Hours & Days of Operation
Normal site hours of operation will be in compliance with the allowable working hours in the
City of Renton which are as follows:
For new single-family residences and non-residential construction, the permitted work hours are
7:00am-8:00pm Monday through Friday, 9:00am-8:00pm Saturday, and no work shall be
permitted on Sunday.
Proposed Hauling/Transportation Routes
Maple Highlands is located on the corner of 162nd Avenue SE and 134th St. The Contractor
anticipates utilizing one haul route to and from SR-169 (See attached Exhibit “A” for location).
Heading north on 154th PL, head north on 156th Ave SE, east on SE 2nd PL, then north on 162nd
Ave SE to the site.
Measures to Minimize Impacts
Harbour Homes and the Contractor will make every effort to minimize the impacts from this
project on the surrounding neighbors, the environment and traffic circulation for the
immediate area. The Contractor and Harbour Homes’ contact information will be clearly posted
at the site and the job trailer to ensure communication and immediate responses to any
questions or inquiries from the community.
Dust/Mud/Erosion Impacts- The Contractor will implement and maintain the TESC measures
approved for The Pines project at all times. Measures such has water trucks, street sweepers
and maintaining perimeter erosion fencing help to mitigate impacts. In addition, regular
inspections by the City of Renton and the project’s certified erosion control and sediment lead
(Earth Solutions Northwest), as well as regular meetings between Harbour Homes and the
Contractor to ensure compliance.
Traffic/Transportation Impacts- Harbour Homes and the Contractor will secure all necessary
Right-of-Way use permits including providing traffic control measures to minimize the impact of
the frontage improvements associated with the project. Haul routes and hours will be adhered
o and Harbour Homes is attempting to minimize the amount of import/export needed on the
project through careful design of the finishing grade within the site. Utilizing the on -site
material and repurposing wood chips and top soil from the clearing activities minimize the need
for ongoing truck and trailer loads.
Noise- The Contractor will comply with the allowable working hours in the City of Renton (see
above) to minimize the impact to neighbors during the site construction and building
construction.
