Golden Valley Surface Water Management Plan Overview
December 2007
The City of Golden Valley's Surface Water Management Plan (SWMP) is a local water management plan
prepared in accordance with Minnesota Statute 103B.235 and Minnesota Rules 8410. The purpose of this
SWMP includes those purposes given in Minnesota Statute 103B.201 for metropolitan water management
programs. According to statute, the purposes of these water management programs are to:
. Protect, preserve, and use natural surface and groundwater sto~age and retention systems;
. Minimize public capital expenditures needed to correct flooding and water quality problems;
. Identify and plan for means to effectively protect and improve surface and groundwater quality;
. Establish more uniform local policies and official controls for surface and groundwater
management;
. Prevent erosion of soil into surface water systems;
. Promote groundwater recharge;
. Protect and enhance fish and wildlife habitat and water recreational facilities; and
. Secure the other benefits associated with proper management of surface and ground water.
In short, the purpose of this Plan is to provide a complete and intensive guide and reference for managing
water resources within the City of Golden Valley. The plan will assist the City with policy decisions, water
resource management, implementation priorities, regulatory program references, and capital
improvement budgeting for water resource issues. This plan will replace the 1999 "City of Golden Valley
Surface Water Management Plan" prepared by HR Green & Associates.
This plan will meet the requirements of Minnesota Statutes 103B.235, Minnesota Rules Chapter 8410,
and the watershed organizations with jurisdiction in the City including the Bassett Creek Watershed
Management Commission and Minnehaha Creek Watershed District.
.
Regulatory History and Background
Besides the purposes and requirements outlined in state statutes and rules, this SWMP reflects numerous
other water resource-related state and federal mandates that the City must meet. As state and federal
laws have changed over the years, the role of the City in water resource management has also changed.
The following paragraphs provide the background and history of some of these mandates (references:
"Minnesota Environment," Minnesota Pollution Control Agency (MPCA), Volume 7, Number I-Summer
2007, the MPCA's website www.pca.state.mn.us. and the City of Plymouth's July I August 2007 edition of
"Environmental Extra").
In 1945, the Minnesota state legislature authorized a new state Water Pollution Control Commission,
because too many communities were dumping raw sewage into lakes and rivers. One of the Commission's
jobs was to encourage communities to build wastewater treatment plants to stop the flow of raw sewage ..
into rivers and lakes.

.
Three years later, in 1948, the United States (U.S.) Congress enacted the Federal Water Pollution Control
Act (FWPCA), in response to the threat that polluted water posed to the public health and welfare.
In 1967, the Minnesota Legislature created the Minnesota Pollution Control Agency, in response to oil
spills and other major environmental incidents. Its mission was to protect the air, land and waters of the
state.
Five years later, in 1972, the U.S. Congress enacted amendments to the FWPCA to address the growing
public awareness and concern for controlling water pollution. This act became known as the Clean Water
Act (CWA).
Amendments to the CW A in 1977 addressed "point source" facilities, such as municipal sewage plants and
industrial facilities. The National Pollutant Discharge Elimination System (NPDES) became the program
for regulation of point source pollution. As a "delegated permitting authority," the MPCA issues combined
State Disposal System (SDS) and NPDES stormwater permits.
In 1987, the Minnesota legislature enacted laws to control polluted runoff, broadening attention from
"point" source to "nonpoint" source pollution, which is the movement of pollutants from land to water,
typically in stormwater or snowmelt runoff from streets, lawns, construction sites, farms, etc. Also in
1987, state regulatory authority for this program was delegated from the U.S. Environmental Protection
Agency (EP A) to the MPCA.
In 1987, an amendment to the federal Clean Water Act required implementation of a two-phase
comprehensive national program to address stormwater runoff.
In 1990, the EP A promulgated regulations establishing the Phase I Stormwater Program. The Phase I
federal regulations required two general categories of stormwater discharges to be covered under a
NPDES stormwater permit: 11 regulated categories of industrial activity including construction activity
that disturbs five or more acres ofland, and municipal separate storm sewer systems (MS4S) serving
populations of 100,000 or more (including Minneapolis and St. Paul).
In 1994 and 1995, the MPCA promulgated rules to establish the Phase I Stormwater Program at the
state level. Under Phase I, Minneapolis and St. Paul obtained individual permits and designed and
implemented stormwater programs.
In 1999, the Phase II federal regulations were promulgated, which expanded the scope of the NPDES
Stormwater Program to include smaller MS4s in urbanized areas, construction activities that disturb
between one and five acres ofland, and smaller municipally owned industrial activities. The MPCA then
promulgated rules related to the Phase II federal regulations to fulfill federal NPDES delegation
responsibilities. The rules establish the NPDES stormWater permit requirements for regulated MS4s,
construction, and industrial activities.
In 2003, Phase II of the NPDES program began. Phase II is a broader program that includes smaller
construction sites, municipally owned or operated industrial activity, and many more municipalities
(MS4s). Regulated parties under the Phase II program must develop stormwater pollution prevention
plans to address their stormwater discharges, and determine the appropriate pollution prevention
practices or "best management practices" to minimize pollution for their specific site. Each of the three
permit types-construction, industrial, MS4-has distinct requirements and some regulated parties may
require more than one permit.
In 2003, the MPCA issued a General Permit for municipalities with populations over 10,000 (MS4
permit), including Golden Valley. The permit requires cities to comply with six "minimum control
measures," which include public education, public outreach, illicit discharge detection and elimination,
Golden VaHey SWMP Overview

Page 2
construction site stormwater runoff control, post-construction stormwater management, and pollution
prevention/ good housekeeping measures.
Approximately 200 MS4s in Minnesota were mandated by the Phase II federal regulations as requiring
NPDES permit coverage; these include municipalities located within the boundaries of an urbanized area.
In 2006, the MPCA issued a new MS4 General Permit. The new permit identifies a group of 30 selected
MS4s that must complete a Loading Assessment and a Nondegradation Report as part of their MS4 Storm
Water Permits. These MS4s must assess the volume of total suspended solids (soil, sand and silt),
phosphorus and water in storm water runoff and establish a non-degradation plan to keep pollutant
loadings at 1988 levels. The City of Golden Valley is not part of this "group of 30," although many ofthe
neighboring cities are part of this group.
The Clean Water Act (CW A) also requires states to adopt water quality standards to protect the nation's
waters. Water quality standards designate beneficial uses for each waterbody and establish criteria that
must be met within the waterbody to maintain the water quality necessary to support its designated
use(s). Section 303(d) ofthe CWA requires each state to identify and establish priorityrankings for
waters that do not meet the water quality standards. The list of impaired waters, sometimes called the
303(d) list, is updated by the states every two years.
In 2002, the MPCA began identifying surface water resources that are impaired for their identified uses
(swimming, aquatic habitat, etc.). As required by the Clean Water Act, if a water body is included on the
impaired waters list, it triggers an analysis called a total maximum daily load (TMDL) study. The TMDL
analysis determines the impaired water body's capacity to assimilate specific pollutants and still meet
water quality standards. A TMDL also develops an allocation scheme amongstthe various contributors-
point sources, non point sources and natural background-as well as a margin of safety.
The above regulations and requirements have led to following specific requirements for the City of Golden
Valley and other similar cities:
. Preparation of the MS4 General Storm Water Permit Application and Storm Water Pollution
Prevention Program
. Preparation of this Surface Water Management Plan (SWMP)
. Preparation of future updates to the NPDES-MS4 permit and SWMP to address the
requirements of future Total Maximum. Daily Loading analyses.

Implementation
.
Section 5 describes the significant components of the City's SWMP implementation program, including its
NPDES Phase II MS4 permit, operation and maintenance of its stormwater system, capital improvement
projects, studies, education and public involvement, funding, ordinance implementation and official
controls, implementation priorities, and SWMP update and amendment procedures.
The City's current ordinances, official controls and future needs are described in Se.ction 4.6.1 of the
SWMP. Some ofthe City's ordinances and official controls are tied with the City's implementation of its
NPDES Phase II MS4 permit. The City's ordinance implementation is incorporated into Part C (official
controls) of the implementation program tables below.
In order to improve the City's efficacy regarding stormwater management the City will pursue three new
additional controls upon the adoption of this plan as follows:
1. Stormwater management ordinance. This new stormwater ordinance will deal with design
requirements relating to the water quality aspects of ponding and other treatment devices and
methods, along with water quantity requirements such as rate and volume controls. This
ordinance will codify the stormwater design requirements of the BCWMC, Met Council, the City's
NPDES permit, and the City's own policies. The stormwater ordinance will also outline process
and the roles of other agencies. This ordinance will also address illicit discharges and new
connections.
2. Wetland management plan and wetland management ordinance. To fill in gaps in the City's
wetland management program, the City will develop a wetland management plan that
consolidates and updates existing inventories, classifications, and wetland assessments. This plan
will also outline strategies (including buffers) to improve/protect those wetlands. Recognizing .
the mostly developed character of the city, the wetland management plan would provide aready
basis for the City to take advantage of future opportunities arising from re-development, grant

.
.
.
funding, public involvement, or other circumstances. It would also provide the basis for
development of buffer standards.
3. Buffer Ordinance to cover wetlands. lakes and streams. A buffer ordinance based on the wetland
plan and on analysis of buffer utility for lakes and streams would then follow the development of
the wetland plan and ordinance.
The implementation program is summarized in a series .of tables on the following pages of this overview,
and at the end of Section 5 ofthe SWMP. Table 5-1 presents the details ofthe implementation program,
including a project description, cost estimate, potential funding sources, and 'proposed years of
implementation. Table 5-2 summarizes the implementation program year-by-year, listing th~ project
number and estimated costs for every year from 2007-2016.
