C 2. All limits of clearing and areas of vegetation preservation as prescribed on the plan shall be clearly flagged
in the field and observed during construction.
0 (f)
F W 3. All required sedimentation/erosion control facilities must be constructed and in operation prior to land clearing
I.—
~O and/or other construction to insure that sediment laden water does not enter the natural drainage system. All
erosion and sediment facilities shall be maintained in a satisfactory condition until such time that clearing
J and/or construction is completed and potential for on -site erosion has passed. The implementation,

n z 4. The erosion and sedimentation control depicted on this drawing are intended to be minimum requirements to
0 meet anticipated site conditions. As construction progresses and unexpected or seasonal conditions
U dictate, the permittee shall anticipate that more erosion and sedimentation control facilities will be necessary to
W ensure complete siltation control on the proposed site. During the course of construction, it shall be the
ry Z obligation and responsibility of the permittee to address any new conditions that may be created by his
Q:� 0 activities and to provide additional facilities, over and above minimum requirements, as may be needed to
Ill (f) protect adjacent properties and water quality of the receiving drainage system.

Lv drainage design, size nor location of pipes, restrictors, channels, or retention facilities.
6. During the time period of November 1 through March 31, all project disturbed soil areas greater than
5,000 square feet, that are to be left unworked for more than twelve (12) hours, shall be covered by mulch,
sodding, or plastic covering.
4.; o 7. In any area which has been stripped of vegetation and where no further work is anticipated for a period
o" of 30 days or more, all disturbed areas must be immediately stabilized with mulching, grass planting or other
41
v approved erosion control treatment. applicable to the time of year in question. Grass seeding alone will
Y be acceptable only during the months of April through September inclusive. Seeding may proceed, however,
0 0 3.0 whenever it is in the interest of the permittee, but must be augmented with mulching, netting, or other
a Q treatment approved by the City of Renton, outside the specified time period.
