CONSTRUCTION MITIGATION DESCRIPTION
Wizards of the Coast Child Care Center Feb. 8, 2000
• Construction is proposed to start by approximately April 24, 2000 and to be completed
by approximately August 24, 2000.
• Construction is expected to occur during typical weekday business hours. Occasional
construction on weekend days may 0ccl.1r, but is not expected at this time.
• Hauling and transportation routes will primarily access the site from the west, via
Raymond Avenue S.W., into the backside of the site. Access from the east, via Lind
Avenue S.W. will be discouraged, although some may occur given the curb cuts along
the east property line are the primary entries to the office campus.
• After existing vegetation is cleared from underlying soils, during excavation for new
retaining wall footings, and while importing and placing soil needed to raise grades for
new outdoor play areas, the affected areas of the site will be sprinkled with water to
minimize fugitive dust. Dust resulting from exposed sails will be minimized by employing
temporary ground cover, or temporary stabilization measures such as seeding, mulching
or matting, per the General Contractor's preference.
• Traffic and transportation impacts are not expected to be noticeable, given the small
scale of the project. The various trades arriving at the site in the morning and leaving at
the end of the day will create all of the traffic impacts. Trades will be staggered
according to their scheduling during construction - not all trades will be on site at any
one time. Since the interior tenant improvement build -out is less than 4,000 square feet,
only a few workers in any one trade will be on site at one time. The greatest traffic
impact will be from trucks bringing imported soils to the site. These trucks will be routed
into the site from the west and all necessary filling will occur within 3 — 4 days.
• The only potential erosion will occur during the limited time that soils are exposed and,
given the context, will only occur over the surface of the existing parking lot, towards the
existing catch basins. In order to limit the transportation of sediment, the areas of the
site to be excavated and filled will be completely surrounded by a straw bale barrier. In
addition, the appropriate catch basins in the vicinity will be outfitted with storm drain inlet
protection such as a filter fabric fence, a concrete block and gravel filter, a gravel and
wire mesh filter, or a straw bale barrier, per the General Contractor's preference.
• Noise impacts are only expected to affect people working in spaces adjacent to the
tenant improvement, within the Wizards of the Coast office campus, and are not
expected to impact adjacent sites.
• Occasional cor istruction on weekend days may occur, but is not planned for at this time.
• Construction -related traffic will be directed to access the project from the back of the
site, via Raymond Avenue S.W.
