Grading, erosion control practices, sediment control practices,
and waterway crossings shall be adequate to prevent transportation
of sediment from the site. The design and construction guidance in
the City stormwater design manual shall be followed insofar as it
is applicable. Other pollutants shall be controlled as necessary to
prevent potential discharge to waters of the state.

shall not begin until all sediment control devices have been installed
and have been stabilized.
D. Cut and fill slopes shall be no steeper than 2:1, except as approved
by the City to meet other community or environmental objectives.
E. Phasing shall be required on all sites disturbing greater than thirty
(30) acres, with the size of each phase to be established at plan
review.

not tracked onto public streets by construction vehicles or washed
into storm drains.
[Ord. No. 3025, 8-7-2018]

be effectively maintained throughout the duration of any inactivity.
B. Soil stockpiles must be stabilized or covered at the end of each
work day unless otherwise protected from allowing sediment to leave
the site.
C. Techniques shall be employed to prevent the blowing of dust or sediment
from the site.
D. Techniques that divert upland runoff past disturbed slopes shall
be employed.
[Ord. No. 3025, 8-7-2018]
A. Sediment controls shall be provided in the form of settling basins
or sediment traps or tanks and perimeter controls.
B. Where possible, settling basins shall be designed in a manner that
allows adaptation to provide long-term stormwater management.
C. Adjacent properties shall be protected by the use of a vegetated
buffer strip in combination with perimeter controls wherever possible.
[Ord. No. 3025, 8-7-2018]
A. A temporary access road or driveway shall be provided at all sites.
B. Regardless of the amount of land disturbance at a particular site,
it shall be the responsibility of the permit holder or property owner

owner shall remedy the issue within twenty-four (24) hours.
[Ord. No. 3025, 8-7-2018]
A. Concrete Truck Washout. Concrete truck washout shall not discharge
surplus concrete or drum wash water on the site except to a planned
containment system, but in no case in such a manner that allows contact
with stormwaters discharging from the site.
B. Construction Waste. All construction waste material shall be collected,
deposited, and stored in a manner to prevent contact with stormwaters
discharging from the site and shall be disposed of by a licensed solid
waste management contractor. No waste shall be buried on the site.
C. Sanitary Waste. A licensed sanitary waste management contractor shall
collect all sanitary waste from portable units that will be maintained
on a regular basis for any site that cannot provide other means of
sanitary waste disposal.
D. Petroleum Products. All construction equipment and vehicles shall
be monitored for leaks and receive regular preventive maintenance
to ensure proper operation and reduce the risk for leaks or spills.
Petroleum products shall be stored in clearly labeled and tightly
sealed containers or tanks. Any soil contaminated by fuel or oil spills
shall be removed and disposed of properly.
E. Fertilizers. Fertilizers shall only be applied following proper soil
sampling and the recommendations of an approved soils lab. Fertilizers
shall be stored in a covered area or in watertight containers. Partially
used products shall be properly sealed and stored to avoid spills
or leaks.
F. Hazardous Materials. Storage areas for hazardous materials such as
oils, greases, paints, fuels, and chemicals shall be provided with
secondary containment to ensure that spills in these areas do not
reach waters of the state. All hazardous waste materials shall be
disposed of according to state regulation or the manufacturer's recommendations.
