and/or to improve the water quality of specific water resources in the City,
especially those waters listed as impaired. Cooperate with the watershed districts in
efforts to complete the required TAifDL studies on impaired waters within
Ma lewood.
3 Provide an appropriate level of storm water treatment upstream of lakes and
wetlands, depending on the wetland's fllllctions, values and management
classification.
4 Use regional storm water treatment structures to enhance water quality by removing
sediment and nutrients from nmoff.
desi ns will meet the national urban nmoff ro ram URP removal standards.
5 All projects using storm water treatment structures shall include a detailed City-
approved maintenance plan that meets City and watershed district standards and
criteria.
6 Design storm water facility inlets to prevent debris from entering the conveyance
system and impeding the flow path. Encourage using BMPs (raingardens, treatment
structures, NURP ponds, etc.) and other detention facilities on all improvement and
reconstruction ro.ects, whenever ractical.
7 Design outlet control structures, wherever practical, that restricts both high and low
flows, to maximize sedimentation and nutrient removal.
8 Continue implementation of the City's education program that includes items about
preserving and improving water quality. Encourage residents and landowners to
practice environmentally friendly lawn care and housekeeping practices, and to use
native lantin or naturallandsca es rather than tur lawns, where a ro riate.

however, builders and developers will be required to reduce peak nmoff rates to the
pre-development 2-year, 10-year, and 1 OO-year recurrence event by using regional
detention facilities, rain ardens, or other on-site detention facilities.
2 Encourage the use of infiltration to reduce nmoffvolumes where practical. All
hydrologic modeling shall be based on ultimate development of the affected
and \vhere not detrrrnental to grolll1chvater sn) )lies
3 The City encourages the pretreatment of storm water. In addition, the City
encourages the use of treatment ponds and infiltration methods for storing storm
water to reduce nmoffrates and volume and to improve the water quality of area
lakes and wetlands.
4 Storm water management improvements shall be designed based on the critical
storm event for, and the ultimate develo ment of, the draina e area.
S Proj ects that affect the storm water system shall have a protected emergency
overflow structure (i.e. swale, spillway) into pond outlet structures to safely convey
excess flows from storms lar er than the 100- ear (1 ercent) event.
6 Maplewood will require minimum building floor elevations to bejIl accordance
with Ci , atershed district. and FEJ'vfA eulations.
7 Maintain existing intercommunity drainage patterns and solve any intercommllllity
drainage issues through cooperation and collaboration with the adjoining city and
the a ro riate watershed district.

Manual" (2001), the Minnesota Pollution Control Agency's "Protecting Water
Quality in Urb an Areas " (2000), and/or the Minnesota Pollution ControlAgency's
2005 Stormwater Manual.
4 Effective energy dissipation devices should be provided at all conveyance system
discharge points to prevent bank, channel, or shoreline erosion. Design of stream
bank stabilization and streambed control measures should consider unique or
special site conditions, energy dissipation potential, adverse effects, preservation of
natural processes and aesthetics, in addition to standard engineering and economic
criteria.
