General Provisions
1. All erosion control measures shown on the plans must be installed prior to commencement of grading
operations and be maintained until all areas altered on the site have been restored.
If silt fence is used, the bottom flap must be buried and the maximum allowable spacing between
posts is 4-foot on center. All posts must be either 2" x 2" pine, hardwood, or steel fence posts. Ifhay
bales are used, all bales must be staked in place and reinforced on the downstream side with snow
fence. The silt fence must be orange in color, which will be more evident and easier to locate for
removal at the completion of the project.
2. All areas altered because of construction must be restored with seed and disced mulch, sod, wood
fiber blanket, or be hard surfaced within two weeks from the completion of construction or no later
than October 1, 2007.
3. Upon completion of construction and restoration of areas disturbed, the permit applicant is
responsible for the removal of all erosion control measures installed throughout the site.
4. Street sweeping must be undertaken and completed on an as-needed basis.
5. At the entryway onto the site, a rock filter dike being a minimum of2 feet in height and having
maximum side slopes of 4: 1 must be constructed. This rock filter dike will enable construction traffic
to enter the site and also provide an erosion control facility.
6. The District must be notified in writing a minimum of 48 hours prior to commencement of
construction. Upon receipt of this notification, a field inspection of the project site by the District's
engineer will be undertaken to ensure that all erosion control measures have been properly installed.
Construction cannot commence until this field inspection has been completed.
7. Upon completion of the project, the permit applicant is required to complete and submit the middle
portion of the attached permit, indicating that the project has been completed. Upon receipt of this
application, a field inspection of the site by the District's engineering advisor will be undertaken to
ensure that all areas have been properly restored and that all erosion control measures throughout the
project site have been removed.
8. The Riley-Purgatory-BluffCreek Watershed District (RPBCWD), its officers, employees and agents
review, comment upon, and approve plans and specifications prepared by permit applicants and their
consultants for the limited administrative purpose of determining whether there is reasonable
assurance that the proposed project will comply with the regulations and criteria of the RPBCWD and
other state and federal agencies. The determination of the RPBCWD that issuance of this permit is
appropriate was made in reliance on the information provided by the applicant.
