(5) Scheduling the site's activities to lessen their impact on erosion and sediment creation, so as to minimize the
amount of exposed soil.
(6) Control storm water runoff as follows:
a. All exposed soil areas with a continuous positive slope within 2001ineal feet of a surface water, must have
temporary erosion protection or permanent cover for the exposed soil azeas, according to the following table of
slopes and time frames �
Type of Slo�e Time'�`
Steeperthan 3:1 7 days
10:1 to 3:1 14 days
Flatterthan 10:1 21 days
� Maximum time an area can remain open when the azea is not actively being worked.
These areas include pond side slopes, and any exposed soil azeas with a positive slope to a storm water
conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch
or other natural or man made systems that discharge to a surface water.
b. Install erosion and sediment controls at locations specified in the storm water management plan. Nlinimum
requirements include silt fences, rock check dams, or other equivalent control measures along slopes. Silt fences
are required along channel edges to reduce sediment reaching channel. Siit fences, rock check dams, etc. must
be regulazly inspected and maintained.
a The work shall conform to the current version of the MPCA's publication, 'Protecting Water Quality in
Urban Areas;' and the current requirements found in the same agency's NPDES/SDS permits for storm water
associated witb construction activities.
(7) Silt fence shall be required to hold ali sheet flow runoff generated at an individual site, untii it can either
infiltrate or seep through silt fence's pores.
(8) Temporary soil stockpiles must have silt fence or other effective sediment controls, and cannot be placed in
surface waters, including storm water conveyances such as curb and gutter systems, or conduits and ditches.
(9) Temporary rock construction entrances are required wherever vehicles enter and exit a site.
(10) Streets must be cleaned and swept whenever tracking of sediments occurs and before sites aze left idle for
weekends and holidays. A regular sweeping schedule shall be established.
(11) Water (impacted by the construction activity) removed from the site by pumping must be treated by
temporary sedimentation basins, geotextile filters, grit chambers, sand filters, up-flow chambers,
hydro-cyclones, swirl concentrators or other appropriate controls. Such water shali not be discharged in a
manner that causes erosion or flooding of the site, receiving channels, adjacent property or a wetland.
(12) All storm drain inlets must be protected during construction until control measures aze in place with either
silt fence or an equivalent.
D y- a�7
(c) Stornz Water Runoff Rate Control Storm water runoff rate control is required for sites larger than one quarter
of an acre which go through the City's Site Plan Review process. Storm water discharge into public storm
sewers shall be controlled, in accordance with the Department of Public Works Policy. Required information to
be submitted as part of the Storm Water Pollution Control Plan is available in a handout from the Department of
Public Works. Peak storm water discharge rates from the site for all storms up to and including the critical
100-year frequency will not exceed:
Q=1.64xA

above the critical 100-yr flood elevation and at least 4 feet above normal groundwater elevation.
(e) Temporary Sediment Basins For common drainage locations that serve an area with 10 or more acres
disturbed at one time, a temporary (or permanent) sediment basin must be provided prior to the runoff leaving
the construction site or entering surface waters. In addition to this requirement, the applicant is encouraged to
install temparary sediment basins where appropriate in azeas with steep slopes or highly erodible soils even if
less than 10 acres drains to one area. The basins must be designed and constructed in accordance with the
current version of the MPCA's General Permit to Dischazge Storm Water Associated with Construction Activity

INI7IATING PROBLEM, ISSUE.OPPOflTUNITV (WHO. WHAT, WHEN, WHEFE, WH`n�
The City of Saint Paul was issued a storm water dischazge permit from the Minnesota Pollution Control Agency (MPCA) on December i,
2000. Under the conditions of this permit, the City is required to adopt a storm water management ordinance. The City is also required to
adopt this ordinance through the local water management planning process. The storm water management ordinance must include measures
to control sediment and erosion during construcGon as well as long term storcn water management for the site. The Department of Public
Works and the Department of License, Inspections and Environmental ProtecGon will jointly enforce this ordinance.

Item 45 - 3/24/04
The draft ordinance is a good first step. In order to enhance its effectiveness, I have a
few suggestions.
- Much of the ordinance repeats the NPDES construction site permit requirements and
does not provide additional wntrols. The effectiveness of the ordinance could be
improved if the minimum site area were reduced or if it applied equafly to
redevelopment (where there is existing impervious areas) as wetl as new development.
- Consider in�rporating an incentive program to promote stormwater management
retrofits. Tax incentinves, reduce stormwater utility fees, and cost-share grants are just
a few options. The Expo Elementary school project partially funded by a St. Paul STAR
grant (in partnership with the Capitol Region Watershed District) is a fine example of
how incentives can work to promote retrofits.
- Standards are the key to any successful stormwater program. Further, practices that
retain/infiltrate/filter runoff on-site are going to have the most dramatic ben�ts.
Accordingly, consider a combination of standards that promote practices that focus on
water quality and volume reduction, such as Table 1.1 from the Vermont Stormwater
Manual (attached).
- There are a number of good model ordinances out there. Dane County, WI has a
great ordinance that can provide additional ideas. See attached.
- Funding is obviously a critical component of any stormwater program. How wilf the
St. Paul program be funded and how will it be implemented?
