RE: Site Plan Review- 800 Garden Avenue- New Mixed Use Apartment Development
In an effort to provide tactical construction impact mitigation, the following plan describes not
only the major components of the project but mitigation measures that will be in place to
minimize the projects impacts on the environment and community as a whole.
Construction Dates:
The project will be built in 3 phases.
Phase I Construction: 2024-2025; Lease-up: 2026-2027
Phase II Construction: 2029-2030; Lease-up: 2031-2032
Phase III Construction: 2034-2035; Lease-up: 2036-2037
Construction hours and Days of Operation:
The project will be under construction Monday through Friday with some minor activities on
Saturdays to avoid delays and complications.
The construction gate will open at 6:00am and the equipment on site will be turned on at
7:00am. The workforce will arrive onsite between 6:00 and 7:00am, with a rollout starting at
7:00am.
The construction gate will close at 6:00ppm and all equipment will be stopped and shut down
by 5:00pm.
The site will always have security fencing in place and the site will be locked during non-
construction hours. Construction access will be controlled, and all visitors must report to the
construction office and must have appropriate safety protection to walk onsite.
Hauling and Transportation Routes:
Most common commuting will be done via i-405 and N. Southport Drive, major trucking and
hauling will likely follow either:
North 8th St/Houser Way- I-405
N. Southport Drive/Garden Ave- I-405
The total travel time to I-405 in either direction is less than 5 minutes.
Mitigation and Control of Impacts on the Surrounding Community:
May 12, 2022
The site will be watered during times when dust reaches a level that is disturbing to the
surrounding areas in the morning and in the late afternoon or as needed to reduce transient
dust from escaping the site and lingering to surrounding areas.
The perimeter of the site will have filter fabric fence installed to gather and hold all debris,
spoils and dirty water from leaving the site without being controlled.
Soil and landscaping material that are collected and/or gathered in amounts exceeding 2 cubic
yards will be covered with visqueen and sandbags to minimize erosion.
During heavy hauling and site delivery times, licensed and independently contracted road crews
and flagging companies will be used to control traffic flow to and from the site. Each activity
that requires traffic flow control will be applied for to the governing authorities and a site
control and access plan will be approved. At times when traffic is heightened during certain
activities, the local law enforcement agency may be contracted to ensure safety of the
community.
The site will have crushed rock and tire gravel at the construction entrance to minimize the
impact on Garden Ave. all dirt and debris that is tracked on to Garden Ave will be swept up by
street sweeping on a regular basis.
The site will have times where noise will exceed common day practices on typical adjacent
properties, but the activities that will affect the community with noise pollution the most will
be controlled based on the times that the work will be taking place and the amount of work
being done at any one time.
The items will be properly placarded, and Material Safety Data Sheets will be on site for each
item. Secured and Safe lockers and/or storage bins will always be used with a properly
developed perimeter to ensure the safety of the items on the site.
Types of Measures that May be Required:
Physical Impacts:
o Traffic detours, temp sidewalks, construction coordination meetings
Environmental impacts:
o Pressure washing sidewalks and driveways
