- Flood Level Determination
- Ultimate development of the tributary watershed shall be assumed.
- Design criteria shall be the 2, 10, and 100-year storms. When using
SCS methodologies for event modeling, the Type II storm distribution
shall be used. The 100-year 10-day snowmelt event shall also be
modeled.
- Flood levels shall be either determined or approved by the District
Engineer.
- Many depressions within the District are landlocked. That is, they have
no surface water outlet. Because there is no surface outlet, runoff
collecting in these depressions is removed only by seepage and
evaporation. Under these circumstances, a detailed flood level analysis
should include the effects of seepage and evaporation. Analysis of this
type can be very complex.
In order to determine appropriate flood levels for these depressions, a
simpler method of analysis was devised. With this method, the
approximate 100-year flood level is determined using the annual runoff
volumes shown in the following table:

a wetland per the WCA and WCA Rules.
- Replacement wetlands shall be located within the District, unless the District
finds the need for exception.
- The District may find that an out of District replacement may have a higher
value than one completed within the District. State banking described in
WCA Rules Chapter 8420.0730 though 8420.0740 can be used by the
applicant provided that replacement locations adhere to requirements stated
elsewhere in these rules.
- Decisions regarding sequencing, replacement plans, and banking shall
particularly favor preservation, restoration, and creation of wetlands in high
priority areas as identified by the District and the WCA Rules part 8420.0350.
High priority areas in the District include but are not exclusive to the following
areas:
- Areas defined as high priority by the District Water Management Plan.
- Minor watersheds having less than 50 percent of original wetlands,
diminished wetlands, eliminated wetlands, and areas once occupied by
wetlands.
- Additional high priority areas defined by the local water management
plans where preservation, enhancement, restoration, and establishment
of wetlands would have high public value by providing benefits for water
quality, flood water retention, public recreation, commercial use, and
other public uses.

Wetland impacts require the following procedures:
|
|
|
- Exemption and no-loss determinations. Exemption and no-loss
determinations under Minnesota Rules parts 8420.0210 and 8420.0220 shall
be made by the LGU. The LGU shall seek the advice of the technical
evaluation panel on questions of wetland delineation and type. The LGU's
decision is final unless appealed within thirty (30) days of its decision.
- Sequencing and replacement plan decisions. Sequencing and replacement
plan decisions under Minnesota Rule part 8420.0520 - .0550 shall be made
following the same procedures as for District permit review plus the additional
notice and time requirements of part 8420.0230. If the amount of wetland to
be drained, ditched, dredged, excavated, or filled is less than one-tenth of an
acre, the sequencing determination under the WCA Rules part 8420.0520
shall be made by the District.
- Monitoring. The District shall assure that the replacement plan monitoring
and enforcement requirements of the WCA Rules part 8420.0600 - .0630 are
fulfilled.
- Storage volume. The alteration shall not reduce the existing storage volume
in the immediate watershed. Storage volume will be determined as stated
elsewhere in these Rules.
- Recording. The applicant is to provide all copies needed for proper
distribution and recording at the time application is made.
- The alteration shall meet all other requirements of these Rules.
- Any requirements or conditions the District deems necessary to ensure the
procedures of this section are carried out.

- Wetland impact shall be replaced as required by the WCA Rules.
- The applicant shall post a cash surety or letter of credit equivalent to
150 percent of the estimated construction cost of the replacement wetland, to
be determined by the permit applicant and approved by the District Engineer.

- Replacement wetlands will require monitoring and annual reporting for
5 years after completion with possible extensions defined in the WCA Rules
