III. Program/Project Updates
Natural Resources Inventory: The City is in the process of performing a natural
resources inventory throughout the City. The inventory has maps showing the
location of natural and non-native communities and are being provided in
electronic and paper format as part of this study.
The April 28, 2003 Environmental Commission meeting will be a joint meeting
with the Open Space and Recreation Commission and the Planning Commission.
At this meeting a presentation identifying the results of the natural resources
inventory will be given by Short, Elliott, Hendrickson Inc.
The DNR would like the City to sign a licensing agreement allowing release of
the endangered species data to the public. Currently the City is incorporating the
data received from the DNR. The data will be specific but users will need to know
how to present it to the public. Baker further explained the agreement to others at
the meeting.
NPDES Phase II: The federal government has mandated Cities with a
population greater than 10,000 to comply with the NPDES Phase II permit.
Golden Valley is in good shape regarding the requirements by the government.
The City's permit has 44 Best Management Practices (BMPs) that it must adhere

to. The City Council has approved the permit application and Lundstrom plans to
submit it to the Minnesota Pollution Control Agency by March 28, 2003.
Lundstrom will supply a copy of the permit to all members of the Commission.
BCWMC Second Generation Plan: Under the same laws as the NPDES Phase II
permit, the BCWMC is required to submit a new water management plan. This
second generation plan focuses on quality water issues. This will be discussed at
the next BCWMC meeting scheduled for April 17, 2003 at noon in the City Hall
Council Conference room. Baker indicated he would attend.
Boone Avenue North and Trunk Highway 55 Project: The City is in the
preliminary design process for the reconstruction of the intersection at Boone
Avenue North and TH 55. The reconstruction is needed as a result of the
General Mills headquarters expansion. General Mills has added additional office
space to its corporate office which will increase traffic levels at this intersection.
Council has also authorized staff to purchase the property at 710 Boone Avenue
North. Seventy percent of this site is wetland. The City is considering
construction of a flood levy in the vicinity of this property. The levy would provide
ponding space and a lift station to alleviate the flooding of the two gas stations
and the intersection of Boone Avenue North and TH 55.
Golden Valley has an agreement with General Mills and the City's consultant,
WSB & Associates Inc. to do a water resource study of the intersection and
surrounding area. The City could receive the land that was proposed for the
Bassett Creek Nature preserve and part of the agreement with General Mills.
This would allow the City to restore the creek back to its original flow. This may
allow General Mills to develop its land near Betty Crocker Drive and General
Mills Boulevard.
Preliminary investigations have been started by WSB. WSB will present its
findings to the Commission in the fall. Oliver will provide the Commission with the
scope of work from WSB.
Wirth Beach: See item number IV.
Proposed Developments: None.
IV. Wirth Lake
A project in the BCWMC CIP included dredging subwatershed FR -5 detention
pond (see attachment), located at TH 55, to improve the water quality of Wirth
Lake. The Minneapolis Park Board is in the feasibility stages of this project.
Lundstrom discussed the project with a representative from the Park Board. He
Minutes of the Golden Valley Environmental Commission

informed Lundstrom that the project is based on funding from the Legislative
Committee for Minnesota Resources (LCMR). This project is presently on hold
pending the State budget cuts.
Kuentz distributed Table 6, Lake Improvement Options for the Wirth Lake
Watershed. Golden Valley contributes approximately 5% to these costs and the
rest is funded through LCMR grants, MnDOT and the Minneapolis Park Board.
Kuentz explained that the FR05 detention pond is located between the park trail
and Wirth Parkway. The water control structure kept the pond level higher than
the lake.
Recently Kuentz noticed that the structure is failing and there is no longer a pond
at this location; it is more of a direct flow into the lake. Sediment is collecting and
the pond is no longer functioning as a settling area. Kuentz believes the structure
should be repaired. Oliver explained that the facility is fully under the
responsibility of the maintenance of the Minneapolis Park Board. Kuentz will
contact Tim Brown at the Board.
V. Bassett Creek Park Pond
The area north of Duluth Street and west of Highway 100 has been surveyed.
The Bassett Creek Park Pond gets significant settlement of sediment. This reach
of Bassett Creek and this pond were identified in the Golden Valley CIP.
Lundstrom distributed a project schedule. Bonestroo, Rosene, Anderlik &
Associates are the City's consultant. Staff will meet with MnDOT in early May.
The Commission will review the preliminary report and design. A neighborhood
meeting will be held later in May. Commission members, Baker and Hill, would
like to attend the neighborhood meeting to hear what the neighbors have to say
about the project. Staff will get back to the Commission next month about
attending neighborhood meetings.
VI. Other Business
Restoring Streams in Cities: At the February meeting, the Commission had
asked the City to purchase a resource book called Restoring Streams in Cities.
Lundstrom has bought the book and it is available to be checked out through
him.
Golden Valley Budget Cuts: Baker asked about the SunPost newspaper article
regarding the City's budget cuts totaling nearly $600,000. Oliver explained the
measures taken by management.
One option is to fold the Environmental Commission under with the Planning
Commission. Members opposed this option. Baker will contact the Mayor and he
Minutes of the Golden Valley Environmental Commission
March 24, 2003
Page 4
suggested that all Commission members contact the City Council members to
discuss this matter. Baker recommended the Commission meet every other
month to save dollars.
Flood Damage Reduction Study: Giese asked about the status of the flood
damage reduction study. Oliver advised that the floodproofing was approved by
the BCWMC on March 20, 2003, and is included in their CIP. The City Council
will hear this matter on April 1.
Attendance of Commission members at City Council Meetings: The Commission
would like members to attend the Golden Valley City Council meetings to make
its present known and to get familiar with how the Council operates. The
following assignments were made:
April 1, 2003 Giese

Natural Resource Inventory
Executive Summary
In 2002, Short Elliott Hendrickson (SEH) completed a natural resources inventory
throughout the City of Golden Valley. The City of Golden Valley was the lead
implementing agency with collaborating partners that included the Minnesota
Department of Natural Resources (MNDNR) and the Hennepin Conservation District
(HCD). Funding was provided through a MNDNR Metro Greenways Planning Grant
with an equal match provided by the City of Golden Valley. The project was
administered by the Public Works Department of the City of Golden Valley (hereafter
referred as the City).
The primary objectives of the Natural Resources Inventory were threefold. First, to
provide the City and metropolitan area with completed mapping of the Minnesota Land
Cover Classification System (MLCCS). The MLCCS is a land cover classification system
developed by the MNDNR. Large areas of the Twin Cities Metro have been, or are in the
process of being, mapped using the MLCCS. Mapping of the City using MLCCS was the
major objective and requirement of the MNDNR Metro Greenways Planning Grant. The
second objective was to identify other important natural resources and resource
management needs within the City. The third major objective was to provide the City
with a natural resources management database that can serve as a source for future
management efforts. The completed MLCCS is one of several tools to be used for long-
term natural resources management and planning.
The results and data collected during the study are presented as natural resource
management units (RMU's). The RMUs are specific geographic areas identified by the
City. Each RMU has a park or open space as a point of reference and are identified
accordingly. Fourteen RMUs were determined and are shown in Figure 1. Natural
resources were identified and assessed, and management opportunities addressed within
each RMU. The following is a list of the RMUs included in this report in the order they
are presented:
1)
Medley Park
2)
Wesley Park
3)
Brookview Park
4)
Westwood Lake
5)
Laurel Avenue Greenbelt
6)
Hampshire Park
7)

CADOCUME-1 \dsomers\LOCALS-1\Temp\EXECUT-1.DOC
In summary, the City's Natural Resources Inventory results reflect a fully developed city
with established parks, open space, trails, and greenways. Most of the natural areas are
mixed woodlands, forests, open water, or wetlands. Nuisance vegetation composition
varies considerably, and ranges from severe infestations of European buckthorn and
purple loosestrife in Wirth Park, to minor infestations of these species in the parks and
open spaces in the remainder of the City. Ecological restoration needs are greatest in the
vegetative communities that are infested with buckthorn and purple loosestrife.
Restoration opportunities are limited in other areas. Existing trails and greenways are
extensive and well planned. Potential trail and greenway opportunities are scattered
within each RMU. Rare, threatened, or endangered species are limited by pre-existing
development, but known occurrences are scattered throughout the City.
The results and database of the MLCCS have been developed into a Geographic
Information System (GIS) database for application and development of management
objectives for natural resources by the City. The GIS database will be combined with the
MNDNR and HCD efforts in the other Metro areas where the MLCCS has been
completed.
The Natural Resources Inventory for the City was completed in spring 2003.

Re: Scope of Services
General Mills/Golf Course Wetland and Floodplain Enhancement Plan
WSB Project No. 1473-00
Dear Ms. Clancy:
As requested, please find outlined below a Scope of Services and cost estimate to develop a
wetland and floodplain enhancement plan within the General Mills and Golf Course sites for
the TH55/ Boone Avenue Improvement Project. The purpose of the work would be to
identify jurisdictional wetlands within the Study area, develop a plan to enhance existing
wetlands, create new wetlands, restore the meander characteristics of Bassett Creek in the
reach north of Betty Crocker Drive, provide additional floodplain storage in the area, and
obtain permits for this work. This project will also provide wetland credits to be deposited
into a wetland bank to be used by the City, General Mills, or Golf Course.
Task I — Collect and Review Background Information. As part of this task, background
information will be collected from various sources. This information will include reviewing
the topography, modeling information, drainage area information, soil survey information,
the National Wetland Inventory, DNR Public Waters Maps, and existing wetland delineation
information.
Task 2A —Develop Preliminary Wetland/Upland Location Map. A map that identifies the
wetland/upland locations will be completed. The purpose of this task will be to better define
wetland areas and use this information to develop concept plans. This task will utilize
historic aerial photo review for the area, soils and NWI mapping information, and a field
visit to develop the preliminary wetland location information. No stakes will be placed
around the wetlands nor will wetland edges be surveyed as part of this task. This will be
completed for the following areas as shown on the attached map:
• Area 1: General Mills property bounded by Betty Crocker Drive, General Mills
Boulevard, the 394 ramp, and the General Mills parking lot.
• Area 2: The Golf Course property.
• Area 3: Wetland in the northeast corner of 7`h Avenue and Boone Avenue.
4150 Olson • Area 4: General Mills property west of General Mills Boulevard, north of Betty
Memorial Highway Crocker Drive, and east of 169.
Suite 300
Task 2B — Complete Functions and Values Assessment of the Wetlands. As partof this
r polis task, the Minnesota Routine Assessment Method (MnRAM) will be completed for the

wetlands reviewed in Task 2A. This assessment will allow the City and General Mills to
make m
pla g decisions about these wetlands and design a wetland enhancement project to
meet the needs of the City, General Mills, and the Golf Course.
Task 2C — Develop Preliminary Concept Plans and Report for the Wetland
Enhancement/Floodplain Storage Project. From the information gathered in the previous
tasks, preliminary concept plans will be developed that will incorporate the creation of
floodplain storage, creation of new wetland, and enhancement of existing wetland areas. It
is anticipated that up to three meetings will be held with General Mill's staff to obtain input
and make certain the plan that is developed will meet the needs of the company to a
maximum reasonable extent. This concept plan will be summarized in a draft report that
will be mZies.
available for review with City Staff, General Mills, other local landowners, and
ew
reviaBased on input from these parties, the concept plan will be finalized.
Task 3 — Complete Formal Wetland Delineation. Once the concept plan is finalized, a
delineation of the jurisdictional wetlands will be completed for those areas that have been
determined to require delineation. This delineation will be in conformance with the US
Corps of Engineers Wetland Delineation Manual (1987). Depending on the options selected
from Task 2, the following areas or portions of the areas could be included for delineation:
Area 1: General Mills property bounded by Betty Crocker Drive, General Mills
Boulevard, the 394 ramp, and the General Mills parking lot.
Area 2: The Golf Course property.
Area 3: Wetland in the northeast corner of 7th Avenue and Boone Avenue.
Informatio from the City and General Mills has indicated that the wetland delineation north
of Betty Crocker Drive has been completed and is accurate; therefore, no additional
delineation is proposed in this area.
This task will include delineating the site(s), surveying the site(s), and developing a Wetland
Delineation Report to be used for permitting purposes. One meeting is included with this
task to review the formal wetland delineation with the appropriate permitting agencies. A
cost estimate for delineation of each area has been developed and is included on the attached
table.
Task 4 — D velop Final Design for a Wetland Enhancement/Creation and Floodplain
Storage Pr 9ject. As part of this task, the information obtained in the previous tasks will be
reviewed aid a final plan for wetland enhancement, wetland creation, and floodplain storage
project wil be developed. This plan will consider the potential to enhance the existing
wetlands, t e amount of floodplain storage needed for the TH55/ Boone Avenue
Improvement Project, and the potential to create additional wetlands in the area. This plan
will also be designed to in conformance with the Wetland Conservation Act and regulations
of the US Corps of Engineers to provide wetland credits to the City. Excess wetland credits
created by the project could be used by the City, General Mills, or the Golf Course for

mitigation of future projects that impact wetlands. This task includes two meetings with
City Staff to review the plans.
Task 5 — Complete Final Report. The information developed from the previous tasks will
be compiled into a report. This report will outline the background information collected, the
results of the functions and values assessments, results of the wetland delineation, review the
concept plans and discuss the plan for the enhancement and creation of wetlands within the
site as well as outline the plans to provide additional floodplain storage. This report will be
prepared and reviewed with the City Staff.
Task 6 — Develop and Submit Permit Applications for Wetland Enhancement Design.
This task includes developing and submitting the appropriate permit applications for the
wetland creation and enhancement project for review and approval. It is anticipated that this
plan will need to be approved/reviewed by the City of Golden Valley as the LGU for WCA,
the US Corps of Engineers, the DNR, and the Bassett Creek Watershed Management
Organization. This application will include a wetland banking application for excess
wetland credits anticipated to be created by the project. This task anticipates up to four
meetings with the agencies and associated follow up.
Cost Estimate and Timeline
The cost estimate to complete this work is $52,265. An itemized estimate is attached for
your review. The preliminary wetland review can be completed in April/May, concept plan
development in June, wetland delineation in July, and report preparation and permit
application submittal by the end of the summer.

STORM WATER POLLUTION PREVENTION PLAN
INTRODUCTION
The City of Golden Valley is included in a group of communities with populations greater
than 10,000 that are federally required to obtain a Municipal Separate Storm Sewer
System (MS4) permit for managing non -point source storm water. Non -point source
storm water is generally the overland flow of storm water that does not originate from a
single pipe, otherwise know as point -source storm water.
The Phase II National Pollution and Discharge Elimination System (NPDES) permitting
process requires cities such as Golden Valley to file a Phase II NPDES permit with the
Minnesota Pollution Control Agency (MPCA) which addresses how the City will regulate
and improve storm water discharges. The permit must include a Storm Water Pollution
Prevention Plan (SWPPP) addressing all the requirements of the permit.
The Public Works Department has managed the permit application process. Several
Department Heads and Managers assisted staff with the permit process. Staff attended
several seminars and meetings collecting information related to the Phase II program.
The City also joined a consortium of Cities coordinated through the League of
Minnesota Cities (LMC) and attended the workshops sponsored by the LMC.
The framework for developing the City's NPDES Phase II permit application and plan is
the City's existing Comprehensive Surface Water Management Plan (SWMP), adopted
in August 1999. The purpose of the Golden Valley Surface Water Management Plan is
to provide a complete and intensive guide and reference for managing surface water
resources within the City of Golden Valley. The plan assists the City with policy
decisions, water resource management, implementation priorities, regulatory program
references, and capital improvement budgeting for water resource issues.
Golden Valley's NPDES Phase II plan addresses the six Minimum Control Measures
(MCMs) outlined in the permit requirements. Many of the Best Management Practices
(BMP), required in the NPDES permit, have already been developed in accordance with
the City's Surface Water Management Plan. The six Minimum Control Measures of the
permit are:
1. Public Outreach and Education
2. Public Participation/Involvement
3. Illicit Discharge Detection and Elimination
4. Construction Site Runoff Control
5. Post Construction Runoff Control
6. Pollution Prevention/Good Housekeeping

EXECUTIVE SUMMARY
The Storm Water Pollution Plan (SWPPP) was developed by the City of Golden Valley
to enhance the integrity of surface water through management of the storm water runoff
within the City. The SWPPP is designed to minimize the discharge of pollutants into the
City's storm water system, to protect and enhance water quality, and to satisfy the
appropriate requirements of the Clean Water Act of 1984. The Goal of the SWPPP is to
prevent unwanted discharges into the City's storm sewer system to the maximum extent
practicable.
The Process
Before beginning selection of Best Management Practices (BMPs) and Measurable
Goals for each Minimum Control Measure required by the permit, City staff undertook a
self-assessment of Golden Valley's storm water system including an evaluation of our
City's conditions, needs, and practices. The objective of this process was to provide a
knowledge base upon which to structure the SWPPP in order to meet the Permit's
Maximum Extent Practicable standard.
The self-assessment was guided by materials included in the League of Minnesota
Cities NPDES Phase II MS4 Guide Plan. This self-assessment process had two major
components:
1. A workshop session organized as part of the LMC Guide Plan project included a
self-assessment component led by Pat Collins of AMEC Earth & Environmental.
This workshop included:
discussion of physical and socio-political watershed and organizational
conditions and issues that should guide the selection of BMPs and
Measurable Goals.
review of two examples of Cities with different characteristics to demonstrate
how local conditions should shape the selection of BMPs and Measurable
Goals.
a series of exercises in which our City staff considered the local conditions for
our community and how they should guide our selection of BMPs and
Measurable Goals.
2. Staff completed NPDES Phase II Program Assessment Questionnaire that was
included in the LMC Guide Plan notebook. This was a twelve -page document
with a comprehensive list of questions that staff used to guide them through a
self-assessment activity, including consideration of a wide range of stormwater
approaches.
The results of this process include:
a set of understandings among City staff regarding storm water management
written notes regarding stormwater management
completed Storm water Program Assessment Questionnaire

This assessment represents our knowledge of Golden Valley's storm water system and
the conditions that shape it. City staff has used the results of this self-assessment
process to guide our selection of BMPs and Measurable Goals that make up the
SWPPP for our Permit Application.
Based on this self-assessment process, the City evaluated many factors in order to
meet the maximum extent practicable standard set forth in the permit. These factors
include sources of pollutants, potentially polluting activities being conducted in the
watershed, sensitivity of receiving waters, uses of receiving waters and other issues of
specific local concern.
In addition to the self-assessment process discussed above, the City considered non -
storm water discharges to determine whether they should be identified as significant
contributors of pollutants to our storm water system. If any of these discharges were
considered significant, they were incorporated into the permit. The City of Golden Valley
did not find any of the additional referenced non -storm water discharges listed above to
be significant contributors of pollutants to the storm water system
Funding Mechanism
The City of Golden Valley established a Storm Water Utility Fee in 1992. The City's
Storm Water Utility revenue is generated by fees according to land use. The Storm
Water Utility Fee is the primary funding source for all storm water improvements related
to the City's Surface Water Management Plan, Pavement Management Program and
NPDES Phase II requirements. The following is a breakdown of the 2003 Storm Water
Utility Fee revenue source:
