subdivisions to the Arden Hills City Code to read as follows:
Chapter 15: Erosion and Sediment Control
Section 1500 — Purpose and Scope
1500.01 Purpose. The purpose of this regulation is to control or eliminate soil erosion and
sedimentation within the City of Arden Hills. The regulation establishes standards and specifications

specified period of time that authorizes the land disturbance activity contingent on the
implementation and completion of the Erosion and Sediment Control Plan.
Subd. 3 Permit Denial. If the PWD determines that the Erosion and Sediment Control
Plan does not meet the requirements of this article, the PWD shall not issue a permit for the
land disturbance activity. The Erosion and Sediment Control Plan must be resubmitted for
1500-7
City of Arden Hills Chapter 15 Erosion and Sediment Control Ordinance
approval before the land disturbance activity begins. No land use and building permits shall
be issued until the Permittee has an approved Erosion and Sediment Control Plan.
1520.03 Escrow Requirement. After approval of an Erosion and Sediment Control Plan, the PWD
may require the Permittee to escrow a sum of money sufficient to ensure the installation, completion,

PWD. In reviewing such application, the PWD may require additional reports and data.
Section 1530 — Implementation and Maintenance
1530.01 Implementation and Maintenance of Plan. All storm water pollution controls noted on the
approved Erosion and Sediment Control Plan shall be installed before commencing the land
disturbing activity and shall not be removed without PWD approval or approval of a Certificate of
Completion. Noncompliance with the Erosion and Sediment Control Plan shall constitute grounds
for an order from the PWD to halt all construction.
1530.02 Implementation. The plan implementation shall incorporate the following:
Subd. 1 Existing vegetation shall be retained whenever feasible.
Subd. 2 Land shall be disturbed in increments of workable size such that adequate erosion
and sediment control can be provided and maintained as construction progresses. The area
exposed shall be stabilized in conformance with best management practices and with the
maintenance requirements in the NPDES General Construction Permit. Soil stabilization
measures should be selected to be appropriate for the time of year, site conditions, and
estimated duration of use.
Subd. 3 The location of areas not to be disturbed shall be identified with flags, stakes,
signs, silt fence, etc. before construction begins.
Subd. 4 Down -gradient sediment controls shall be in place before up -gradient land
disturbing activity begins.
Subd. 5 All storm drains, inlets and outfalls shall be protected until all sources of potential
discharge are stabilized.
Subd. 6 Temporary stockpiles shall have effective sediment control and can not be placed
in surface waters or storm water conveyance systems.

all stormwater pollution controls and soil stabilization measures in conformance with best
management practices and with the maintenance requirements in the NPDES General Construction

all damages caused by flooding of the site or surrounding area due to in -place erosion or sediment
control.
