DEB GARROSS, ASSISTANT CITY PLANNER
DISTRIBUTION OF FLOOD PLAIN MANAGEMENT
ORDINANCE
AUGUST 20, 1990
The purpose of this item is to present the
Citr Council with draft Ordinance 90-04 which
is l.ntended to amend the City of Prior Lake
Flood Plain Ordinance. The Planning
commission held a public hearing to consider
Ordinance 90-04 on August 2, 1990 and
recommends approval. The document contains
twentr-two pages. It is the intent to
distrl.bute the document on August 20, to allow
the Council an opportunity to review the
Ordinance. At this point, it is the intention
of staff to place the Flood Plain Ordinance on
the consent agenda for the first meeting in
September. If there are any questions
pertaining to the Ordinance, please contact
Deb Garross prior to August 27, 1990. Staff
will schedule the Flood Plain Management
Ordinance as a discussion item if so desired
by the City Council.
On February 15, 1989, the Department of
Natural Resources, Division of Waters Staff
met with Horst Graser to discuss the City's
Flood plain Management Ordinance. staff was
notified that the existing Flood Plain
Ordinance is minimally non-compliant with the
National Flood Insurance Program requirements
which were recently modified. The areas that
were in need of amendment concerned
definitions and the addition of a section
pertaining to travel trailers and travel
vehicles. DNR staff informed the City via a
letter dated March 16, 1989, that the existing
Flood Plain Ordinance must be amended to be
compliant with FEMA standards.
The existing Flood Plain Ordinance was adopted
by the City Council on September 5, 1978. The
DNR recommended that staff utilize a prototype
ordinance for reference in order to amend and
4629 Dakota St. S.E., Prior Lake, Minnesota 55372 / Ph. (612) 447-4230 / Fax (612) 4474245
ACTION REQUIRED:
bring into compliance, the Flood Plain
Ordinance for the City of Prior Lake. Staff
has taken several months to prepare the
attached draft of Ordinance 90-04. The draft
has been reviewed by the Department of Natural
Resources and is compliant with revised FEMA
standards. Please note that the ordinance
does not follow a ~rototype. Rather, staff
has written the ordl.nance to reflect the needs
and procedures implemented by the City of
Prior Lake.
The Ordinance reflects current practice of the
City of Prior Lake in reviewing site plans and
construction activity within the flood plain.
One change that is proposed concerns the
Administrative Review Process located on page
12. staff proposes to submit all building
permit and grading and filling permits
proposed within the Flood Plain District to
the DNR for review and comment prior to
issuance of a permit for construction or
filling activit~. The concurrent review
procedure is d1fferent from the existing
ordinance however, DNR review is necessary for
all Shoreland District activities and is
currentlr required as part of the excavating
and filll.ng permit process.
The Planning Commission recommends approval of
attached Flood Plain Management Ordinance
90-04. The DNR has reviewed the document and
has stated that it meets FEMA requirements.
staff feels that it is important to amend the
ordinance in a timely manner in order to
insure continued participation with the
National Flood Insurance Program.
No action is required at this time.

Dear Ms. Garross:
CONDITIONAL STATE APPROVAL OF DRAFT FLOODPLAIN ORDINANCE
The Department of Natural Resources has completed its review of the draft
ordinance the City of Prior lake is considering for adoption. The ordinance was
entitled Flood Plain Management Ordinance. Ord. 90-04.
Our review determined that the ordinance was not yet totally compl iant with
"Statewide Standards and Criteria for Management of Floodplain Areas of
Minnesota," Minnesota Regulations, Parts 6120.5000 to 6120.6200. Please take
appropriate steps to revise the draft ordinance consistent with the following
1 isted items:
1. In Section 1.1 Statutory Authorization, fill in the blank listing the
zoning enabling statute for municipalities (462).
2. In Section 3 Definitions, include in the definition for structure
"factories, sheds, detached garages, cabins, manufactured homes, travel
trailers/vehicles not meeting the exemption criteria specified in
Section 8.3 of the ordinance and other similar items' from Section 2.826
of the model ordinance.
We anticipate that you agree to make these amendments to the draft ordinance
prior to holding the public hearing. Consequently, on behalf of the
Commissioner of Natural Resources, I hereby conditionally certify state approval
of the above cited draft ordinance in accordance with Minnesota Statutes,
Section 104.04.
This approval is valid upon receipt of three (3) certified, signed copies of the
formally adopted ordinance (including the necessary revisions cited above) by
Area Hydrologist Patrick lynch located at the following address:
DNR-Division of Waters
1200 Warner Road
St. Paul, MN 55106

Any changes of the subject draft ordinance prior to adoption (other than those
cited above) must be approved by this agency prior to adoption before they can
be considered valid. Also be advised that any future amendments of this
ordinance or change in the designation of flood prone areas requires prior
approval of the Commissioner.
Note that you are required to send copies of hearing notices and final decisions
relating to variances and conditional use permits relating to this ordinance to
the Department. Please send these directly to Area Hydrologist Patrick Lynch
and rely on him for assistance in administering your ordinance.
Since your administration of a floodplain zoning ordinance is a pre-requisite of
your eligibility in the National Flood Insurance Program, a certified copy of
the adopted ordinance will be sent by this office to the Federal Emergency
Management Agency.
Your cooperation and initiative in providing for the reduction in flood damage
through the administration of this ordinance is greatly appreciated.
Sincerely,
RH/BA:fw

CITY OF
PRIOR LAKE
Dear Mayor Andren:
COM~'1UNITY ASSESSMENT VISIT, NATIONAL FLOOD INSURANCE PROGRAM
Thank you for allowing Horst Graser of your staff to meet with both Mike Mueller
and Bill Zachmann from the DNR-Division of Waters on February 15, 1989, to
discuss flood plain management in Prior Lake. The meeting was conducted by our
staff on behalf of the Federal Emergency f1anagement Agency (FEMA) in
consideration of your community's continued participation in the National Flood
Insurance Program (NFIP).
During the course of the meeting, several topics were discussed, 2 of which
require follow-up action by the city, as described below.
1. The city's ordinance is minimally non-compliant with the NFIP requirements
due to recent modifications to the regulations. Floodplain controls must
be updated or amended by August 15, 1989. We are supplying Mr. Graser with
two model ordinances which may be appropriatE for Prior Lake's needs. We
note that the city is in the unique position of not having a traditional
floodway (that portion of the floodplain that carries the major volume and
velocity of a flood) since only lake level flooding is possible. For this
reason, both of the enclosed model ordinances may require further
refinements based on the city's land use planning goals. The
"One-District/One-Map" format treats the entire floodplain area as a
"Floodwayll, and while allowing open space uses, recreational uses, marinas
and accessory structures among others, habitable structures are prohibited.
The IIThree-District/One-Mapll format is less restrictive, wherein new
residential uses would be allowea providing certain conditions and
performance criteria are met. Area Hydrologist Mike Mueller is available
to assist the city and review any proposed floodplain ordinance drafts.
Since state law requires the DNR to approve locally proposed floodplain
controls 30 days prior to the previously noted adoption due date, please
make sure to supply Mr. Mueller with any draft ordinances prior to July 15,
1989.

2. As a result of the recent outlet control structure installation on Prior
Lake, it is possible the 100-year base-flood elevation of 9091 above mean
sea level may be too high. We encourage the city to consider the benefits
of requesting a "Letter of Nap Revision" (L<>>1R) from FEMA. The LOMR
request could utilize local topographic information and data generated by
the engineering studies to install the control structure to possibly lower
the base flood elevation for a specific subdivision or concentrated area.
An approach that would better address the whole map is the Limited Map
Maintenance Program (LMMP) wherein FEMA would utilize any new data
generated since the original Flood Insurance Study to revise the extent
and elevation of the base flood. This process is much lengthier and we are
currently keeping a list of potential LMMP communities that we will submit
to FEMA later this year. In either case, more accurate flood elevation
data could benefit the community by reducing flood insurance premiums for
affected homeowners. Pages 22 and 23 of the enclosed "Questions and
Answers about the National Flood Insurance Program" provide information
about the LOMR process.
In closing, the city is commended for doing a fine job of floOdplain management
and ordinance implementation. Should you have any questions relating to routine
floodplain management they should continue to be directed to Mike Mueller at
296-7523. If you or your staff have any questions regarding this assessment
please contact Mr. Zachmann at 296-9224.

Explanation of 1988 Changes in the
Sample Floodplain Zoning Ordinance
for a
3 - District, Two - Map.
Local Government Unit
( Section l:/No Changes
\,---~
Section 2: Primary change was to definitions in Section 2.8. It was felt that
adding definitions of Conditional Use and variance would make the ordinance more
understandable (the definitions provided are consistent with the proposed
definitions to be provided in the consolidated planning and zoning statute under
considerations). These two definitions are optional.
A definition of "Basement" was added to essentially deal with enclosed, below
grade areas such as crawl spaces or non-residential below grade enclosed areas.
If these types of below grade spaces are allowed for new construction/additions,
then this definition must be added along with the standards contained in
Sections 5.42 and 5.43.
Section 3: The compliance language was moved to Section 3.0 and expanded to
warn against the more common mistakes and oversights that are made by local
building code officials. This language is not mandatory but strongly
recolmlended.
Section 4.0: The format of this section was revised to more clearly state which
uses are permitted or conditionally permitted and the applicable development
standards for each. This new format is recolmlended but not required. Other
changes to this section include:
-Provisions for .regulating rnve1.-tra""ers and travel vehicles consistent
with FEMA1s new standards (also see Section 9.3). rf-the cOlmlunity allows
travel vehicles not meeting the exemptions in Section 9.31, then the
language in Sections 4.37, 5.56 and 9.3 or something similar IdfI be
in~luded in their ordinance.
-Section 4.0, and specifically 4.38, was amended to ~nd a max1mum
~yea~o~U~e1ght for agricultural levees that protected crops only.
-Section 4.44 was amended to require a long-term site and ultimate
development plan for uses':-requ;,.ing storage fot: significant volumes of
materials in the floodway. This language is recommended for communities
having to deal with long-term dredge spoil operation, sand and gravel
businesses, etc.
-Section 4.45 was amended to clarify which accessory structures can be
wet-flood, in lieu of dry flood proofing. ~a community's existing
ordinance presently a'1cws wet-floodproofed accessory structures (see
language in Sections 4.33 and 5.12 of 1978, 3-District Sample Ordinance),
the language now provided in 4.45 ~ be included in the ordinance.
*Similar changes apply to other lecal government units with variations on this
ordinance type.

NOTICE OF PUBLIC HEARING
TO REVISE THE PRIOR LAKE FLOOD PLAIN ORDINANCE
You are hereby notified that the Planning commission will hold a
Public Hearing in the Prior Lake City Council Chambers at 4629
Dakota street S.E., on Thursday, August 2, 1990 at 8:00 p.m.
The pur~ose of the hearing is to consider proposed amendments to
the Pr10r Lake Flood Plain Ordinance. The existing Flood Plain
Ordinance has been in effect since September 5, 1978. The City
of Prior Lake participates in a Federal program known as The
National Flood Insurance Program. This program allows property
owners to purchase federally backed flood insurance to protect
themselves from future flood losses.
In return for this insurance protection, Prior Lake enforces
flood plain management measures to reduce flood risks to homes
and new development. The Flood Plain Ordinance affects the Lakes
of Upper and Lower Prior Lakes, Spring Lake and Pike Lake. The
City of Prior Lake has been contacted by the Department of
Natural Resources and advised that the current ordinance must be
updated in order to continue participation with the NFIP
Program.
The primary changes from the existin9 to the proposed Flood Plain
Management Ordinance include the add1tion of several definitions:
new provisions regulating the placement of travel trailers and
travel vehicles within the flood plain; changes to height
requirements for agricultural levees: storage requirements for
materials within the floodway; and flood proofing standards for
accessory structures.
A copy of the existing and pro~osed Flood Plain Ordinances are on
file with the Prior Lake Plannl.ng Department and are available
for review and or purchase from City Hall. You may obtain a copy
of either ordinance or find out more about Flood Plain
Management by contacting Deb Garross or Horst Graser at 447-4230.
If you desire to be heard in reference to this matter, you should
attend this hearing. The Planning Commission will accept oral
and or written comments. If you have questions regarding this
matter" contact the Prior Lake Planning Department at 447-4230.

SECTION 1: STATUTORY AUTHORIZATION, FINDINGS OF FACT AND PURPOSE
1.1 STATUTORY AUTHORIZATION: The legislature of the state
of Minnesota has, in Minnesota Statutes Chapter 104 and
462 (Zoning Enabling Statute) delegated the
responsibility to local government units to adopt
regulations designed to minimize flood losses.
Therefore, the City Council of Prior Lake, Minnesota
does ordain as follows:
1.2 FINDINGS OF FACT:
(A) The flood hazard areas of Prior Lake, Minnesota,
are subject to periodic inundation which results in
potential loss of life, loss of property, health
and safety hazards, disruption of commerce and
governmental services, extraordinary public
expenditures for flood protection and relief, and
impairment of the tax base, all of which adversely
affect the public health, safety, and general
welfare.
(B) Methods Used to Analyze Flood Hazards. This
Ordinance is based upon a reasonable method of
analyzing flood hazards which is consistent with
the standards established by the Minnesota
Department of Natural Resources.
1.3 STATEMENT OF PURPOSE: It is the purpose of this
Ordinance to promote the public health, safety, and
general welfare and to minimize those losses described
1n Chapter 1.2 by provisions contained herein.

A7.
2.2 ESTABLISHMENT OF OFFICIAL MAP: The Flood Insurance
Rate Map dated September 29, 1978, is hereby adopted by
reference and declared to be a part of this Ordinance.
A Flood Insurance Rate Map has been published for Prior
Lake and the Regulatory Floodway Boundary is shown on
the map. The Flood Insurance Study for the City of
Prior Lake prepared by the Federal Insurance
Administration dated March 1978 is also declared to be a
part of this Ordinance. The Official Flood Ma~ shall be
on file in the Office of the Director of Plannl.ng.
2.3 REGULATORY FLOOD PROTECTION ELEVATION: The Regulatory
Flood Protection Elevation shall be the elevation of the
Regional Flood plus any increases in flood elevation
caused by encroachments on the flood plain that result
from designation of a floodway.
2.4 INTERPRETATION:
(A) In their interpretation and application, the
provisions of this Ordinance shall be held to be
minimum requirements and shall be liberally
construed in favor of the Cit~ of Prior Lake and
shall not be deemed a limitatl.on or repeal of any
other powers granted by State Statutes.
(B) The boundaries of the Flood Plain District shall
be determined by reference to the Flood Insurance
Rate Map. Where interpretation is needed as to the
exact location of the boundaries of the Flood Plain
District, for example where there appears to be a
conflict between a mapped boundary and actual field
conditions and there is a formal appeal of the
decision of the Director of Planning, the Planning
Commission shall make the necessary interpretation.
All decisions will be based on elevations of the
regional (lOO-year) flood profile and other
available technical data.
2
2.5 ABROGATION AND GREATER RESTRICTIONS: It is not
intended by this Ordinance to repeal, abrogate, or
impair any existing easements, covenants, or deed

(A)
(B)
(C)
(D)
No such use shall be expanded, changed, enlarged or
altered in a way which increases its
nonconformity.
Any alteration or addition to a nonconforming
structure or nonconforming use which would result
in increasing the flood damage potential of that
structure or use shall be protected to the
Regulatory Flood Protection Elevation in accordance
with any of the elevation on fill or flood proofing
techniques (i.e., FP-1 through FP-4 flood proofing
classifications) allowable in the State Building
Code, except as further restricted in 10.l(C)
below.
The cost of any structural alterations or additions
to any nonconforming structure over the life of the
