805230J\WSP 1
The 1995 Water Supply Plan, as mandated by Chapter 186 of the 1993 Minnesota legislative
session laws, was developed to meet the intent of the Minnesota Department of Natural
Resources (DNR) and Metropolitan Council guidelines (attached as Appendix A) for water
emergency and conservation plans. This plan provided the Joint Water Commission (JWC) and
its customers guidance for water system emergencies and a conservation plan for the JWC's
water system.
The Metropolitan Council requires communities with municipal water supplies in the
metropolitan area to periodically submit updates to their Comprehensive Plans, which include
the Water Supply Plans. The purpose of this update to the 1995 Water Supply Plan is to fulfill
the conservation planning requirements of the DNR, and to meet the Comprehensive Plan
requirements of the Metropolitan Council.
The Water Supply Plan Update is divided into four parts. The first part includes analysis of the
current status of the water system, water demand, and supplies. The second part outlines
emergency planning for public water supplies. The third part contains the water conservation
plan. The fourth part itemizes the plan elements required by Chapter 186 in the metropolitan
area.

PART 1. WATER SUPPLY SYSTEM DESCRIPTION AND EVALUATION
DNR Water Appropriation Permit Number: Not Applicable
Name of Water Supplier: Joint Water Commission
Address: 7800 Golden Valley Road, Golden Valley, MN 55427 -4588
Contact Person: Jeannine Clancy, Public Works Director, City of Golden Valley, (612) 593-
8000
Population of Service Area: 66,064
Total Number of Service Connections: 20,091
The cities of Crystal, Golden Valley, and New Hope share a water system, operated by the Joint
Water Commission (JWC). The system serves a population of 66,000. The JWC purchases
treated water from the City of Minneapolis, supplied through two metered connections from the
Minneapolis system. The JWC system provides 3.5 million gallons of elevated storage and 28.0
million gallons of ground storage, which is pumped into the system by booster stations located
in Crystal and Golden Valley. A map of the JWC water system is included as Figure 1 -1.
A. ANALYSIS OF WATER DEMAND
A.1. Summary of Historic Water Use
Table 1 -1 presents historic water service data from 1988 through 1998 including population, the
number of service connections and water use data for each individual city, and totals for the
JWC. The data was obtained from City pumping and water billing records. There is no water
sales data available before 1988.
As shown in Table 1 -1, the population, volume of water sold and the number of service
connections have shown relatively little variability over the last eleven years. In fact, population
for the JWC has been decreased over the last five years. Significant variations in water use
over the last ten years are mainly due to variations in climate. Water use in 1988 and 1989 was
significantly higher than any other years due to severely dry weather. Water use was notably
lower in 1993 due to higher than normal summer precipitation. Excluding 1988, 1989 and
1993, water use has not varied by more than twelve percent in any of the three communities, or
the JWC as a whole. Water purchased from Minneapolis has not vaned by more than eight
percent over the same period.
A.2. Per Capita Water Use
Per capita water use and per capita residential water use is summarized in Table 1 -2. Per capita
water use is determined by dividing the total water usage, including residential, commercial and
industrial users, per day by the total service area population, and is typically expressed as
gallons per capita per day (GPCD). Total per capita water use has averaged 109 GPCD over
the last eleven years. Data on residential water use was provided for 1991 through 1998. The
residential per capita water consumption rate is calculated by dividing the average residential
daily water consumption by the total number of residents. It has averaged 78 GPCD during this
period. These levels of water consumption fall within the range normally expected for
residential water use.
805230) \WSP 3
A.3. Water Demand by Customer Category
Past annual water sales data provided by JWC member cities were broken down into several
customer categories including residential, commercial and industrial. The water sales records
for each city, as well as totals for the JWC are shown in Tables 1 -3, 1 -4, 1 -5, and 1 -6. Data
showing water sales by customer categories for the individual cities was available for 1993
through 1998. The available data indicates that residential water use has been the largest
demand category in the JWC, averaging 93 percent of total water use in Crystal, 65 percent in
Golden Valley and 78 percent in New Hope. Commercial and industrial water use combined
has averaged 7 percent of total water use in Crystal, 35 percent in Golden Valley and 22
percent in New Hope. Total water use for the JWC has averaged 75 percent residential, 22
percent commercial and three percent industrial.
As in all water systems, some of the water produced is never purchased by water system
customers. The difference between the water produced and the water sold is referred to as
unaccounted -for water use. It can result from many factors including unidentified leaks in th
distribution system, watermain breaks, periodic fire hydrant flushing, unmetered hockey rink
flooding, tank drainage for maintenance purposes, unauthorized use, unmetered services, and
inaccurate meters. Unaccounted -for water use below 10 percent can be usually explained by
normal system leakage and meter inaccuracies and is considered acceptable.
Unaccounted -for water use for the JWC is estimated by comparing the average annual water
purchased from the City of Minneapolis with the average annual metered consumption of the
JWC customers and is shown in Table 1 -7. The unaccounted -for water use has ranged from
zero to five percent of the total water purchased from Minneapolis, which is below the national
average of seven percent. The JWC splits the unaccounted -for water among the three cities
based on water use.
The JWC has seen inconsistencies in the water loss data between 1988 and 1998. In 1989 the
volume of water purchased from Minneapolis was actually lower than the volume of water billed
to the customers and resulted in a negative value for the unaccounted -for water use. Extremely
low values for unaccounted -for water were also measured in 1988 and 1993. These
inconsistencies are likely due to inaccurate water meters. Crystal, Golden Valley and New
Hope are currently replacing customer water meters to more accurately measure water use and
improve the measurement of unaccounted -for water use. The JWC should also work with the
City of Minneapolis to have the meters at their systems' interconnections calibrated regularly.
A.4. Large Volume Customers
High volume users are defined as water customers that use more than five percent of the total
water consumption. There are currently no high volume water consumers in the JWC water
service area.
A.5. Seasonal and Peak Water Demands
Table 1 -8 presents seasonal water demands from 1988 through 1998. Demands from January
and July of each year were used as estimates of winter and summer water use, respectively.
As shown in the table, summer use has averaged 150 percent of winter use. High summer
water use is due to a seasonal increase in non - essential water uses such as lawn and garden
watering and recreational uses. Monthly water use data is included in Appendix B. Monthly
demands separated by customer category are not available.
805230J\WSP 4
Peak day demands, and peak day to average day ratios are listed in Table 1 -9. The record peak
demand was 25.95 MGD and occurred on June 13, 1988. Peak day to average day ratios have
ranged from 1.49 to 2.71 and have averaged 2.18.
�., AaA
B.1. Water Treatment Plant Capacity
The JWC currently purchases treated potable water from the City of Minneapolis and does not
have a water treatment plant. As the supplier of the treated water, it is Minneapolis'
responsibility to deliver water to the JWC that meets Primary Drinking Water Standards.
Current water treatment in the Minneapolis water treatment plant consists of lime softening,
filtration, fluoridation, and chlorination.
B.2. Storage Capacity
The JWC water system operates as one pressure zone. Storage in the system is provided by
five ground storage reservoirs and three elevated water tanks. The locations of the reservoirs,
storage tanks and interconnections are shown in Figure 1 -1. The Golden Valley ground
reservoir system consists of two 4.5 million- gallon (MG) tanks. The reservoirs typically receive
water from the City of Minneapolis during the night between 11 p.m. and 6 a.m. Water from the
reservoirs is then pumped into the distribution system by five vertical turbine pumps, each with a
rated capacity of 4,000 gallons per minute (gpm). The Crystal ground reservoir system consists
of two 4.5 -MG tanks and one 10 -MG tank located just north of the Crystal Utility Department.
Similarly, Minneapolis water typically fills the reservoirs between 11 p.m. and 6 a.m. There are
five vertical turbine pumps in the booster station; each rated at 4,500 gpm.
The JWC water system has three elevated water tanks, one in Golden Valley and two in New
Hope. These tanks offer a total of 3.5 million - gallon storage capacity for the system and are
used to store water during the low demand period and release water during high demand
periods, fire events, or emergency situations.
With an interruption of the Minneapolis water supply, there is a maximum of 31.5 million gallons
of water reserve in the five ground reservoirs and three elevated water tanks, assuming all the
reservoirs and elevated water tanks are full when the supply is interrupted. This water reserve
could continue to support the average day demand of the entire system for over four days. To
date, storage has been adequate to meet all demands.
Elevated water tanks have a daily mission of storing water when the system demand is low and
releasing water back to the system when the demand exceeds the pumping capacity. Ground
storage reservoirs do not have this function because water in ground reservoirs must be
pumped for use. The role of elevated water tanks becomes particularly important during the
maximum day when the peak domestic demand and the fire demand must be provided
simultaneously.
805230J\WSP 5
C. SOURCE OF WATER SUPPLY
The JWC currently purchases treated potable water from the City of Minneapolis and has no
wells or surface water intakes. The JWC water system receives all of its water through metered
interconnections with the Minneapolis system. The City of Minneapolis takes water from the
Mississippi River at a structure located in the City of Fridley. From there, the water is conveyed
to water treatment facilities where it is treated to potable standards. It is distributed to the
Minneapolis service area and surrounding suburbs including Crystal, Golden Valley, and New
Hope.
The adequacy of the source of water supply to meet future system demand is discussed in the
next section.
D. ADEQUACY OF SYSTEM TO SUPPLY DEMAND
D.I. Historic Water Level
The JWC currently purchases treated water from the City of Minneapolis and has no production
wells or surface water intakes. Historic water level data is not applicable to JWC water system.
The DNR and the Metropolitan Council should refer to the City of Minneapolis Water Supply
Plan for this information.
D.2. Adequacy of the Resource to Sustain Current and Projected Demands
The JWC currently purchases treated water from the City of Minneapolis, which uses surface
water from the Mississippi River as its raw water source. The JWC does not have any data to
determine the adequacy of the Mississippi River to sustain current and projected demands. The
DNR and the Metropolitan Council should refer to the City of Minneapolis Water Supply Plan for
this information.
D.3. Adequacy of the Existing Water System to Sustain Current and Projected Demands
In order to evaluate the existing system's ability to meet future water demands, water use
projections for each city, and for the JWC as a whole were computed. Projections are based on
growth projections, Metropolitan Council's population projections and water use trends observed
over the past ten years.
D.3.1. Projected Growth
The Cities of Crystal, Golden Valley, and New Hope are among the first tier suburbs of the
Minneapolis area. During the 1950's and 1960's, population in these Cities exploded rapidly
due to the post -war housing boom. By 1970, the development in the Cities essentially grew to
saturation. Since then, population has declined, attributable to shrinking household or family
size, caused, most likely, by children growing up and leaving home. There are only a very few
vacant parcels scattered throughout the planning area that are suitable for development. It is
anticipated that the development of remaining vacant land will not significantly impact the Cities'
population unless a major redevelopment should occur.
805230J \W S P 6
The Metropolitan Council's population projection does not take into account the population
increase due to large scale redevelopment, such as the Crystal Municipal Airport
redevelopment. As stated in the Crystal Comprehensive Plan, when the State Legislature
eventually recognizes the importance of redevelopment, tax increment financing will be
resurrected or a new tool will be created in its place to provide for the locally determined
replacement of obsolete land uses. When that time arrives, the City of Crystal intends to
facilitate the redevelopment of the airport site.
In the City of Golden Valley, several redevelopment projects have been planned. Due to the
size of the redevelopment sites, these projects are not expected to have a significant impact on
the City's population and water consumption rate.
The City of New Hope currently has no redevelopment plans. Although there are some
undeveloped lots scattered around the City which are zoned for industrial, commercial, and
residential development, these developments are small scale and their population increase
have been included in the population projection by Metropolitan Council.
D.3.2. Projected Demand
The water use projections are based on the following assumptions:
• Population will stabilize based on the Metropolitan Council's population projections;
• Per capita consumption will be reduced as the result of water conservation to 104 gpcd
by 2010. It will be reduced to 100 gpcd by 2020;
• Maximum day to average day water demand is assumed to be 2.40 and will decrease to
2.0 by the year 2020;
• The ratio of peak hourly water demand to maximum daily water demand will be no
greater than 2.0.
While per capita use in 1988 and 1989 reached over 130 gpcd due to the drought conditions,
the average per capita water use over the last eleven years has averaged 109 gpcd. Excluding
data from 1988 and 1989 and 1993, which was an exceptionally low demand year, per capita
water use averages 104 gpcd. The JWC has seen per capita water use range between 93 and
106 gpcd over the last seven years.
Because Crystal, Golden Valley and New Hope have ordinances which have called for
restriction in water use only when the City of Minneapolis has restricted water use, the data from
the past ten years reflects unrestricted water demands. There were very few water conservation
policies in place in 1988 and 1989, which resulted in unrestricted water use. It is unlikely that
demands in the Metropolitan area will reach these levels in the future, as cities have begun to
implement water conservation plans to avoid high water demand situations similar to 1988 and
1989. Assuming that effective water conservation policies are adopted by Minneapolis, Crystal,
Golden Valley and New Hope, per capita water use can be reduced from 108 gpcd in 2000 to
104 gpcd in 2010 and to 100 gpcd by 2020.
Peak day demands from 1988 through 1997 were used to develop peak day to average day
ratios for future years. The ratios have averaged 2.18 and have ranged from 1.49 in 1993 to
2.71 in 1988. Peak day demands in the JWC have all occurred during the summer. Because
the JWC water use shows great seasonal variability (shown in Table 1 -8), reducing seasonal use
and the corresponding peak day demands will be a target of the JWC conservation plan.
Projected peak day to average day ratios are projected to be 2.4 in 2000 and can be reduced to
2.0 by 2020.
805230J \W S P 7
Tables 1 -10, 1 -11, and 1 -12 present the projected water demand in the Crystal, Golden Valley
and New Hope for the next twenty years. Table 1 -13 presents the aggregate total water use
projections for the JWC.
To check the adequacy of the existing system to meet the projected demands, the storage and
pumping capacity were analyzed. Table 1 -14 provides a summary of the capacity of the water
supply components of the water system. As shown in Table 1 -13, average demand is expected
to be 7.28 MGD and projected maximum day demand is expected to reach 17.47 MGD in the
year 2000. The year 2000 demand projections were used to evaluate the existing system's
storage and pumping capacity to meet demands because they are greater than the projections
for future years.
D.3.3. Storage
The existing storage must be able to meet peak domestic demand and the fire demand
simultaneously. Because Minneapolis provides water to the JWC between 11 p.m. and 6 a.m.,
the JWC must supply all demand from storage during off - delivery times.
The Insurance Services Office (ISO) recommends that the JWC be able to supply a 3,500 gpm
fire flow for three hours (0.63 MG). Therefore, a maximum day demand with a fire condition
requires 18.1 MG of water. The JWC's total storage capacity of 31.5 MG is sufficient to meet the
maximum day plus fire flow condition.
D.3.4. Pumping Capacity
In addition to having sufficient storage capacity, there must also be sufficient pumping capacity
to meet the peak hour demand. Although peak hour data was not available, the peak hour
demand was estimated using a peak hour to maximum day ratio of 2.0. This is a value
commonly used for design purposes. Using 2.0 times the maximum day demand of 17.47
results in a required pumping capacity of 34.94 MGD. The JWC's firm pumping capacity of 49
MGD is more than adequate to meet peak hour pumping capacity requirements, even with fire
flow requirements taken into consideration. Therefore, the existing pumping capacities are
adequate to meet the projected demand.
D.4. Plans to Expand or Modify the System
Since the current water system is adequate to provide both storage and firm pumping capacities
during maximum day demand through 2020, the JWC has no current plans and does not
anticipate any future plans to expand or modify the system. Repair and replacement of worn
equipment will take place on a regular schedule and on an as- needed basis.
805230) \W5P 8
E. SUMMARY OF DATA
The service population and the water use have both remained relatively stable over the last
seven years, following the high water use associated with the drought in 1988 and 1989. A
significant increase in water demand in summer months over that in winter months, has been
observed indicating that much of the excess water use is due to seasonal lawn and garden
watering and recreational uses. Per capita water use falls within the range normally expected
for residential water use.
Population is expected to increase only slightly over the next twenty years as development in
Crystal, Golden Valley and New Hope has reached near capacity. The implementation of an
effective conservation plan is anticipated to reduce average per capita water use by eight
percent and reduce the peak day volume by over 3.0 MGD by 2020.
Based on the demand projections for 2000 through 2020, the existing water supply is adequate
to meet the water demands through 2020.

PART II. EMERGENCY PLAN FOR PUBLIC WATER SYSTEM
INTRODUCTION
The purpose of the Emergency (contingency) Plan is to increase emergency preparedness and
to provide the Joint Water Commission (JWC) with a course of action to follow during conditions
that require a curtailment of water service. Potential situations that could reduce water service
include natural disasters such as drought, flood or tornado, contamination of the Mississippi
River, or operational difficulties with JWC or Minneapolis treatment or distribution systems. The
Emergency Plan for the public water system should be incorporated into an overall Emergency
Plan for each of the member Cities, which would also include the areas of electrical power,
police, and fire departments. The plan should also be closely coordinated with the City of
Minneapolis.
A. EMERGENCY TELEPHONE LIST
In the event of an emergency condition, it is critical that the appropriate individuals and agencies
are contacted. Emergency Telephone Lists, Table II -1 and II -2, have been created which list all
city staff, including representatives from Minneapolis, and various agency contacts that would
need to be contacted in the event of a water related emergency. The telephone lists should be
posted conspicuously at all key locations within the water supply and distribution system.
Table II -3 presents the individuals from the JWC member cities and the City of Minneapolis who
are part of the Emergency Event Evaluation Team. The table lists their emergency
assignments, and which agencies they are responsible for contacting in the event of an
emergency. During an emergency condition, all available members of the Emergency Event
Evaluation Team will evaluate the condition, contact the appropriate agencies and determine
the best response to the emergency condition.
All of these tables should be reviewed and updated yearly by the JWC.
Joint Water Commission and member city staff receiving phone calls from outside need to be
trained to collect all necessary information when an individual contacts the JWC to report an
emergency condition. In addition, the JWC should have an emergency response form that is
available to staff and operators. This form would ensure that all critical information is reported.
Some items to be considered in the emergency form include the following:
1. Name, phone number, and address of individual reporting the emergency.
2. City staff member who took down the information, date and time emergency was
reported.
3. Where is the emergency site; address or approximate location
4. A brief description of the emergency.
5. Any conditions at site of which emergency staff should be aware?
6. Who else has been contacted regarding this emergency condition? Are these
individuals taking any type of action (such as calling other communities or
agencies)?
7. Is there currently any emergency personnel on site?
18
Rnsinn.nwsp
8. Any other critical information?
Table II -5 lists items that need to be considered in the emergency form
B. CURRENT WATER SOURCES AND SERVICE AREA
The cities of Crystal, Golden Valley, and New Hope share a water system, operated by the Joint
Water Commission (JWC). The system serves a population of 66,000. The JWC purchases
treated water from the City of Minneapolis, supplied through two metered connections with the
Minneapolis system. The JWC system provides 3.5 million gallons of elevated storage and 28.0
million gallons of ground storage, which is pumped into the system by booster stations located
in Crystal and Golden Valley. A map of the JWC water system is included as Figure 1 -1.
C. PROCEDURE FOR AUGMENTING WATER SUPPLIES
Potential sources of water that can be used to augment or replace existing sources have been
examined and are presented below.
C.1. Interconnect with Adjacent Communities
As discussed in Part I, the JWC receives their water from the Minneapolis Water Works. There
are two separate connections, a 36 -inch connection in Crystal and a 48 -inch connection in
Golden Valley. The JWC has no interconnections with any adjacent communities other than the
Minneapolis connections. Although the contract with Minneapolis limits the JWC from
contracting for water from other suppliers, they are currently investigating an interconnection
with Saint Louis Park. The interconnection with Saint Louis Park is listed in the Capital
Improvements Plan for 2000.
To minimize the effect of a possible interruption of water supply due to a spill in the Mississippi
River, the Joint Water Commission is considering installation of a 16 -inch diameter emergency
interconnection with the City of St. Louis Park. St. Louis Park does not have adequate water
supply capacity to meet both their own maximum day needs and the JWC's maximum day
needs. On a maximum day condition, St. Louis Park could be able to provide the Joint Water
Commission with up to 3 MGD with their current system. However, St. Louis Park should be
able to provide the Joint Water Commission's average day demand if the water emergency
should occur during a normal demand period.
Based on conversations with surrounding communities, the Cities of Brooklyn Park, and
Plymouth are also interested in interconnections with the JWC system. Both of these water
systems have sufficient excess capacity during average demand conditions and Brooklyn Park
has excess capacity during maximum day conditions.
CA.a. Name of interconnecting water systems that supply water to your system
As mentioned above, the City of Minneapolis is the JWC's sole source of supply. There are
currently no other communities interconnected with the JWC. An emergency interconnection
with St. Louis Park is planned for 2000.
CA.b. Water which you provide to interconnected systems
The JWC does not provide water to any other water systems. With the installation of an
emergency interconnection with Saint Louis Park, the JWC will have the ability to provide water
to Saint Louis Park during an emergency condition.
19
An5 ?3nJ \WSP
CA.c. Private Water Sources
Connecting to private wells requires that the private well owner have sufficient extra capacity to
provide water to the JWC. Two companies, General Mills and Honeywell, have wells with
sufficient capacity that could be used by the JWC.
General Mills Wells
General Mills has two different locations in Golden Valley, the Main Campus and the James
Ford Bell Technical Center. Both locations were contacted for this study. General Mills is
interested in connecting to the JWC system as a potential reserve supplier.
The Main Campus has four wells; two 1,000 gpm wells for domestic supply (one is a backup),
and two 800 gpm wells for cooling (one is a backup). According to General Mills, only 1,000
gpm could be used by the JWC on a continuous basis. This water is becoming available
because the Minnesota Department of Natural Resources is requiring that General Mills
eliminate their once - through cooling process by the year 2000. At that time, General Mills plans
on having modified their cooling system to a closed loop system which will allow 1000 gpm to be
available for use by the JWC.
The James Ford Bell (JFB) Technical Center has three wells with a combined capacity of more
than 3,000 gpm. Of the three wells, there is one well for domestic supply, one for cooling, and
one for backup. The JFB Technical Center is also changing their cooling process so that the
cooling well is no longer required. The cooling well would be able to provide approximately
1,000 gpm.
There is a 12 -inch connection between the General Mills Main Campus and the JWC
distribution system in Golden Valley. This connection is valved -off and is only set up for flow
from JWC to General Mills. The General Mills water system uses chlorination and fluoridation
for their potable water. The Generals Mills water supply is suitable as an emergency water
source but would not be suitable for normal daily use without water treatment. This is due to the
fact that the JWC customers are used to treated water (including softening) from Minneapolis
and it is likely that well water would not be acceptable to the JWC customers during normal
operation.
The JWC is considering a 16 -inch connection to General Mills' James Ford Bell Research
Center but does not have any current plans to go ahead with the interconnection.
Honeywell Wells
Honeywell has two wells with a total capacity of 2,000 gpm in their Golden Valley headquarters.
These wells are used for industrial processing, once - through air conditioning, and domestic
usage. Due to the limited well capacity there is no excess capacity available for use by the
JWC. An interconnection with Honeywell would only be available for use during a severe
emergency because of the limited well capacity. Therefore the limited benefits of the
interconnection may not offset the costs of the interconnection.
20
sus ?,in. m.s p
C.2. Conjunctive Use of Surface and Groundwaters
The JWC currently relies on surface water from the Mississippi River that has been treated and
conveyed to the JWC by the City of Minneapolis. The interconnection with St. Louis Park would
provide the JWC with a groundwater source that could be used in the event of an emergency, or
if the Mississippi River or Minneapolis system were unavailable to the JWC. Currently there are
no plans to use the St. Louis Park connection for anything other than an emergency source of
supply. The JWC does not plan on using the St. Louis Park connection for normal operating, in
part because of the water quality differences between the Minneapolis and St. Louis Park
waters and because the current contract with Minneapolis prevents the JWC from contracting
with other systems for water supply. Blending the two would likely result in water quality
complaints which would be acceptable only during emergency conditions.
C.3. Alternative Sources of Water
Currently, there are no alternative sources of water available for the JWC. The JWC
understands the risk that elimination of the Mississippi River poses to the water supply. The
JWC is currently working on a study with Barr Engineering to evaluate options for an alternative
water source that would supply the system in the event the Mississippi River, or the Minneapolis
system is not available as a water source.
The JWC has discussed both drought conditions and river water contamination as different
water shortage situations. In the event of a drought, it is likely that the Mississippi River would
be maintained as a viable source through river controls upstream of the Twin Cities. The JWC
would initiate demand reduction measures to reduce river withdrawals in this case.
Contamination of the Mississippi River presents a different emergency situation. In this case, it
would be favorable to have interconnections with water suppliers that provide water from an
alternate source. In pursuing interconnections with the City of St. Louis Park and General Mills,
the JWC is not only increasing their potential water supply, but is varying the source. While
mixing groundwater and surface water can produce water that is aesthetically unpleasant, this
would be an acceptable practice in an emergency situation.
In the ultimate situation, the Department of Public Safety - Emergency Management Division
would be contacted for community disaster assistance. It is likely that, at this stage, the National
Guard would either supply water by truck or provide portable water treatment plants.
The JWC plans to further develop emergency strategies as part of the contract negotiations with
Minneapolis.
D. DEMAND REDUCTION MEASURES
D.1. Demand Reduction Potential
Minnesota Statutes 103G.261 establishes priorities for water allocation during periods of limited
water supply. These definitions of the are included in Part II.E. Based on the priorities
described in Part II.E., much of the water use in the JWC is considered first priority or typically
residential water use. Commercial and industrial users that consume less than 10,000 gallons
per day are considered second priority users. The JWC has no 3rd, or 4th priority water use.
Commercial and industrial users who use more than 10,000 gallons per day are considered fifth
priority users. Sixth priority includes non - essential water uses such as lawn sprinkling, vehicle
washing, and golf course and park irrigation.
21
8n.92mjwsP
Limited data is available to allocate water use by statutory priority but estimates were made
using 1994 water use data to produce the following table.

To estimate the first priority domestic demand, residential water use from 1994 was used. The
annual residential water use was divided by 365 days to get the estimated average day
domestic use of 5.197 MGD. The non - essential water use included in this estimate should be
compensated for by the domestic use that occurs in the other customer categories. Combined
commercial and industrial uses were split among second and fifth priority categories. Sixth
priority water use which represents lawn sprinkling and unaccounted -for water use was
determined based on the difference between the total water pumped and the cumulative
demand of 1st through 5th priority water use. These are close estimates considering monthly or
seasonal data by customer category was not available.
Water use in the JWC increases by fifty percent during the summer months. High summer water
use and peak day demands are mostly a result of sixth priority water use, such as lawn and
garden watering, vehicle washing and other recreational uses. The best potential for short -term
reductions in demand is associated with reducing these non - essential summer uses. This can
be accomplished through limiting or banning sprinkling and vehicle washing. Options for long-
term reductions in demand are presented in Part III (Conservation Plan).
Most of the industrial users have minimal potential for short -term demand reduction. A reduction
in short -term demand at the industrial plants would typically affect the plant process. The best
potential for reduction in industrial use is through long -term reductions by increasing water
efficiencies at the industrial plants.
D.2. Short -Term Demand Reduction Procedures
In the event that a short -term demand reduction is deemed necessary, the JWC's Emergency
Event Evaluation Team would meet and decide what measures to take. Following is a list of
potential reduction measures.
22
805930.AW S P
Stage 1 : Voluntary Reduction Measures: Contact the media including local television,
radio stations and newspapers and issue a notice to the member Cities that there is
an imminent water shortage and request a voluntary water reduction from residents.
Voluntary reduction measures would include odd /even sprinkling during the
summer, or during the winter it would include minimizing bath use, reducing shower
length, and other measures to reduce interior water use, mainly among domestic
users. The impacts of voluntary reductions in water use are difficult to determine,
as data from conservation and non - conservation periods are not available. The
amount saved will likely be minimal in the first years of use before public education
efforts are realized. An average reduction in per capita use of 1 gallon per day
would reduce demand by 0.07 MGD (one - percent of total daily demand).
Stage 2: Mandatory Sprinkling Bans: Implement a total sprinkling ban in an extreme
emergency. The sprinkling ban ordinance makes violation of the sprinkling ban a
petty misdemeanor. Customers that violate the sprinkling ban can be written a
citation by a City police officer. People that do not pay their citations can be held in
contempt of court. Theoretically, the sprinkling ban should nearly eliminate sixth
priority use which was estimated as 0.37 MGD (or five - percent of the total daily
water demand) based on 1994 water use data.
Stage 3: Mandatory Water Allocation Restrictions: Based on the length and severity of
the emergency conditions, water use should be decreased based on the priorities
defined in Part II. E. Based on 1994 water use data, elimination of sixth priority uses
will reduce water demand by 0.37 MGD (five - percent of total water demand).
Second and fifth priority uses account for 25- percent of the total water use.
Reductions in second and fifth priority uses of ten - percent combined with
elimination of sixth priority water uses would reduce total daily demand to 6.85
MGD, a reduction of almost eight percent.
The following procedure for water allocation is recommended by Minnesota Statute 103G.261.
First Priority Domestic water supply, excluding industrial and commercial uses of
municipal water supply, and use for power production that meets contingency
requirements. According to MN Rules 6115.0630, Subp. 9, domestic use is defined as
use for general household purposes for human needs such as cooking, cleaning,
drinking, washing, and waste disposal, and for on -farm livestock watering excluding
commercial livestock operations which use more than 10,000 gallons per day.
Second Priority Water uses involving consumption of less than 10,000 gallons per day.
Third Priority Agricultural irrigation and processing of agricultural products.
Fourth Priority Power production in excess of the use provided for in the contingency
plan under first priority.
Fifth Priority Uses, other than agricultural irrigation, processing of agricultural products,
and power production.
Sixth Priority Non - essential uses. These uses are defined by Minnesota Statutes
103G.291 as lawn sprinkling, vehicle washing, golf course and park irrigation, and other
non- essential uses.
23
sns93n msp
Allocation procedures should distribute water equitably within each water use priority and
customer category. Non - essential uses of water are the lowest use priority and will be the first
water use subject to allocation restrictions. Quick responses to restrict non - essential uses of
water during periods of limited supplies will help protect domestic and economic uses of water.
Water used for human needs at hospitals, nursing homes, and similar types of facilities should
be designated as high priority to be maintained in an emergency. Local water allocation will
need to address water used for other human needs at other types of facilities such as hotels,
office buildings, and manufacturing plants. Domestic use must have priority over economic
needs.
The JWC plans to inform all water customers of their water allocation priority classification, and
provide them with information on potential demand reduction procedures.
F. TRIGGERS FOR IMPLEMENTING PLAN COMPONENTS
An important part of reducing short -term demand is establishing triggers for implementing the
various water reduction measures. However, the JWC is somewhat limited in its ability to
implement demand reduction procedures due to restrictive language in their water supply
contract with the City of Minneapolis, which is currently under negotiation. The result of their
current negotiations will have a major impact on how the JWC operates in the future, including
what demand reduction measures can be implemented. The JWC may also develop some of its
own supply capabilities to meet peak demands, or provide emergency supply if the Minneapolis
supply is not available. Once the Minneapolis contract issues are resolved, the JWC can
update their Emergency Plan as it relates to water emergencies, backup supplies, emergency
procedures, demand reduction regulations and enforcement.
To establish triggers, the existing water sources were examined. The JWC is dependent on its
storage reservoirs, pumping capacity, the connections with the Minneapolis distribution system
and the Mississippi River source to meet the water demand of its customers. During an
emergency condition, the JWC could get water from the City of Minneapolis, the proposed
interconnect with Saint Louis Park, private wells, or under an extreme emergency, by bringing in
portable water treatment plants to treat water from one of the local lakes or by bringing in bottled
water. The JWC is also currently studying other alternative water sources to supplement supply
and provide water if the Mississippi River was unavailable as a water source, and is purchasing
a generator to supply emergency power to the pumping facilities in Golden Valley.
The critical components of the JWC system are the total storage volume, operation of the
ground storage pumping facilities and the availability of water from Minneapolis. Triggers for
implementing short -term reduction measures are designed to reflect restrictions in these supply
components due to high demand periods, equipment failure, or limited water source capacity.
The triggers shown in Table II -4 are guidelines to be considered by the Emergency Evaluation
Team in the event of an emergency condition that warrants a short-term reduction in demand.
These triggers should be reviewed following contract negotiations with Minneapolis.
The combined storage of 31.5 MG can provide more than four times the current average day
demand of 6.66 MGD. During periods of limited supply from Minneapolis the system would have
adequate storage to supply average day demand for four days, assuming the storage tanks
were operating at full capacity, and that the pumping facilities were in service. Triggers are set
to ask for voluntary water use reductions when storage falls below 12 MG. Mandatory
reductions in non - essential uses will be implemented when demands cause storage to fall below
8 MG. Second and fifth priority water use will be constrained when demands cause storage to
remain below 7 MG (one day of storage).
24
tins ?3n.imsp
The total storage volume includes 28 MG of ground storage, and 3.5 MG of elevated storage.
Reductions in firm pumping capacity due to power outages, or equipment failure would limit the
system's ability to provide water, especially under peak day demands. Triggers have been
established that reflect both situations. Water demands will approach firm pumping capacities
under periods of high demands, and under average demands with reductions in pumping
capacity.
The JWC and the City of Minneapolis will need to coordinate closely in the event of a water
supply shortage. Through the current contract negotiation with the City of Minneapolis, the JWC
should determine the volume of water that would be available to the JWC system in an
emergency situation. This information should be incorporated into the JWC's triggers and
emergency plan. In the event of an long -term water shortage, such as contamination of the
Mississippi River, the JWC would rely on the future interconnect with Saint Louis Park, or a
connection to an alternative supply, which is currently being studied.
G. ENFORCEMENT
A critical factor in an effective reduction in short -term demand is enforcement. Police, City staff,
and concerned citizens can provide monitoring to ensure that all residents are complying.
Implementation of the demand reduction measures listed in the previous section is currently
limited by the contract with the City of Minneapolis. As part of the contract negotiation, the JWC
will clarify issues related to their ability to declare water emergencies independent of the City of
Minneapolis. The JWC recognizes that it should adopt uniform regulations, enforcement
procedures and penalties for non - compliance in all of its member cities. The cities should also
coordinate with the City of Minneapolis to adopt similar regulations, but should plan to maintain
the ability to include provisions specific to operation of the JWC system.
Currently, Crystal and New Hope both have ordinances for controlling short -term water demand.
Following is the portion of the New Hope City Code that relates to short-term water demand:
5.08 Water Sprinkling Ban
5.081 Purpose. The City Council has determined that in certain drought
conditions it may become necessary for the protection of the health,
welfare and safety of the citizens of New Hope to conserve the water
supply of the City by imposing a water sprinkling ban on all residential,
commercial and industrial lawn and garden vegetation. Also, New Hope's
contract with the City of Minneapolis for the purchase of water requires
the imposition of a water sprinkling ban at the direction of the City of
Minneapolis. The purpose of this section is to set forth the nature and
extent of the regulations controlling any sprinkling ban imposed by the
Council.
5.082 Resolution Imposing Ban. All water sprinkling bans shall be imposed by
adoption of a resolution at any regular or special meeting of the New
Hope City Council. The resolution shall set forth the duration of the ban,
whether the ban shall be partial or absolute, if a partial ban, whether it
shall apply to lawns and boulevards only or also to gardens, new sod
and /or new tree saplings, the days or schedule when sprinkling will be
permitted under a partial ban, and any other regulations that the City
Council deems reasonable and appropriate. Said ban shall become
effective immediately upon the adoption of said resolution.
25
sn52in.imsp
5.083 Notice of Ban. The resolution imposing the sprinkling ban shall be
published once in the official newspaper of the City, and conspicuously
posted in four places throughout the City. Any deficiencies in this notice
requirement shall invalidate the ban.
5.084 Enforcement. A violation of this section shall be a petty misdemeanor.
However, a first offense shall not result in the issuance of a ticket. The
owner, any occupant of legal age or party responsible for water billing
shall be first issued a warning ticket upon the first violation of the water
sprinkling ban. A warning letter mailed to the occupant of the property or
the individual responsible for the water billing at the violating property
shall satisfy the warning notice requirement of this section. Each act of
violation and each day a violation occurs or continues constitutes a
separate offense.
Following is the portion of the Crystal City Code that relates to short -term water demand:
715.29 Restrictions against sprinkling; other limitations of water use Water
customers and consumers are governed by the applicable regulations
promulgated by the City of Minneapolis as to the limitations in the time and
manner of using water and such other applicable regulations promulgated by
the JWC affecting the preservation, regulations and protection of the water
supply. If the City Council determined that a shortage of water supply
threatens the City, the council may by resolution limit the times and hours
during which water may be used for anything other than in home use during
the period covered by the resolution. A daily penalty will be charged for this
violation as provided in Appendix IV. Charges will be added to that person's
next utility bill.
The City of Golden Valley does not have any ordinances regulating water use. Based on the
water supply contract with Minneapolis, during water supply shortages they implement water
restrictions in accordance with Minneapolis' water restrictions. As stated earlier, the JWC plans
to standardize water use regulations and enforcement procedures and penalties among all of
the communities after renegotiating the water supply contract with the City of Minneapolis.
H. WATER SUPPLY PROTECTION
H.I. Analysis of Previous Supply Problems
The JWC has not had any previous problems supplying the demand of its customers. Sprinkling
bans have been implemented in the past to comply with the JWC's agreement to implement a
ban when Minneapolis does.
H.2. Wellhead Protection
Since the JWC does not use groundwater as a water source, they will not be required by the
Minnesota Department of Health to submit a Wellhead Protection Plan (WHP).
26
so.s2in.imsP
H.3. Resource Monitoring
The JWC obtains its water from the City of Minneapolis. Minneapolis uses the Mississippi River
for its water source. The JWC does not have any information on water levels and withdrawals. It
is recommended that the DNR and the Metropolitan Council refer to the Minneapolis Water
Supply Plan for this information.

PART III. WATER CONSERVATION PLAN
INTRODUCTION
The purpose of the water conservation plan is to provide the water utility with a procedure for
optimizing available water resources. Short-term water demand reductions can be
accomplished by implementing the emergency procedures presented in Part 11. Long -term water
conservation is an important part in managing available water resources. The member cities of
the JWC intend to establish identical water conservation programs to decrease water
consumption over the long term.
A. ROLE OF CONSERVATION
An effective conservation program will increase efficient water use, decrease water demand,
and determine and address water loss and waste problems. By reducing the total water use and
increasing the efficiency of water use, a water utility can often postpone development of new
water facilities, and decrease operations costs such as energy (pumping) and chemical costs.
B. WATER CONSERVATION POTENTIAL
Each of the JWC's customer categories has been analyzed to determine the best potential for
water conservation. Using the information from water use data presented in Section I., it was
determined that water use has averaged around 75 percent residential, 22 percent commercial,
and three percent industrial. Seasonal water use data indicates that summertime use increases
to 150 percent of average winter use. The excess seasonal use will be a target of the JWC
conservation plan.
The residential customer category was selected as having the most potential for water
conservation because of the total water volume used and the potential for reducing peak use.
Commercial customers were selected as the customer category with the second highest
potential for water conservation.
Another potential area for water conservation is unaccounted -for water use. Watermain leaks,
unmetered connections and fire department use all contribute to unaccounted for water. The
total potential for unaccounted -for water use conservation is dependent on where the water is
going. For example, there typically is little potential to reduce fire department use. Although the
average volume of unaccounted -for water has been low, discrepancies exist in the data. There
are years when more water was sold then introduced into the system. Planned meter
replacements and regular calibration and maintenance programs will improve measurement of
water use and help identify if there is water loss problem. The JWC plans to annually review the
water billing versus water supplied information to monitor unaccounted for water use, which has
not been accurately measured in the past.
By the adoption of this plan, the JWC will set the following goal to reduce residential per capita
water use. The City's ten -year goal will be to reduce residential per capita use 5.3 percent, from
75 gpcd to 71 gpcd. This will be accomplished through a customer education program,
conservation ordinances, conservation- oriented water rates, a meter replacement program and
efforts to increase the number of low -flow fixtures.
31
805230J\wsP
C. WATER CONSERVATION PROGRAMS
As previously mentioned, water conservation can be accomplished through short-term or long-
term methods. The short-term methods were presented in Part II and will not be reiterated here.
Long -term conservation is accomplished by improving water use efficiencies. Specific elements
that should be considered in a long -term water conservation plan are:
1.
Metering
2.
Water Audits, Leak Detection, and Repair
3.
Conservation - Oriented Water Rates
4.
Regulation
5.
Education and Information Programs
6.
Retrofitting Programs
7.
Pressure Reduction
These seven items are discussed as they relate to the JWC.
C.1. Metering
All JWC customers are metered. City utility personnel go door -to -door to record meter readings
from remote totalizers. The billing staff then records the meter reading into a billing software
program. The billing staff reviews the meter readings for unusual readings as they enter the
data.
The City of Crystal checks meters during winter months when utility work has slowed down. The
City determines a route and then utility staff go door -to -door checking as many meters as they
can. Crystal also checks meters when customers request that they be checked or when the
meter readings indicate, as determined by the utility staff or by computer software, that the
meter may be inaccurate.
The City of Golden Valley checks meters when customers request that they be checked or
when the meter readings indicate, as determined by the utility staff or by computer software,
that the meter may be inaccurate. Golden Valley changed out all residential meters between
1982 and 1985. The City is planning to conduct an accuracy analysis of residential meters by
checking a sample of 100 meters.
The City of New Hope checks meters when customers request that they be checked or when
the meter readings indicate, as determined by the utility staff or by computer software, that the
meter may be inaccurate.
All three member cities have meter replacement programs underway, or planned for 2000. After
the meter replacement, the cities will be using the same metering system, using radio read
meters and common billing software. The JWC intends that the new metering system will
improve metering accuracy and efficiency, and will help to track water losses. The system will
have the capability to detect water use violations when water bans are implemented. Once the
program is completed, a program for maintenance and calibration will be established. The JWC
intends for the program to be identical in all three member cities. The JWC should also calibrate
their pump station meters and confirm that they are within the meters' rated accuracy.
32
80593O.AW S P
C.2. Water Audits, Leak Detection and Repair
Unaccounted -for water loss is the difference between water purchased from Minneapolis and
water sold to the JWC customers. Unaccounted -for water use in the JWC system has averaged
around 2.5% for the last ten years, excluding 1989 when negative unaccounted -for water use
was recorded. Given the history of low water loss in the system, the JWC does not plan to
implement a leak detection program. However, if unaccounted -for water use increases after the
meters have been replaced and calibrated, the JWC may consider implementing a leak
detection program.
The American Water Works Association (AWWA) has published two books related to leaks and
unaccounted -for water, which the City should consider purchasing. The titles of the two books
are "Leaks in Water Distribution Systems" and "Water Audits and Leak Detection ". These books
would be helpful if the member cities decide to conduct a leak detection program.
C.3. Conservation- Oriented Water Rates
Each of the three member cities bill the customers in their respective cities. The water rates vary
from city to city, but each city uses a uniform rate structure. All three cities bill their customers
quarterly for water use.
Following are summaries of the water rate structures for each member city:
C.3.1. City of Crystal Water Rates
Crystal has two basic charges, a quarterly service charge based on meter size and the water
use charge. The quarterly service charge is based on meter size and is designed to cover the
cost of meter maintenance, system maintenance, meter reading, and billing and collection of
accounts. The quarterly service charge is $15.90 for meters less than 1 -inch diameter (these
are mostly residential customers). Senior citizens get a discounted quarterly service charge of
$12.40 for meters less than 1 -inch diameter.
The water use charge is based on the volume of water consumed, and is designed to cover the
cost of water purchase, pumping (including chemical costs), system maintenance, and capital
expenditures (replacement of the system). The City charges $1.29 per 100 cubic feet (1998
rate). The City reviews water rates every year and will adopt a conservation- oriented rate
structure similar to Golden Valley and New Hope as part of the JWC conservation program.
C.3.2. City of Golden Valley Water Rates
Golden Valley charges its customers based on water use. There is a minimum quarterly fee of
$15.00 for water meter sizes up to and including 1 -inch diameter. This quarterly fee includes up
to 10,000 gallons of water use. Quarterly water use over 10,000 gallons is charged at a rate of
$1.70 per 1,000 gallons (1998 rate). The water rate is based on the volume of water consumed,
and is designed to cover all costs associated with operating and maintaining the water system.
The City reviews water rates every year and will adopt a conservation- oriented rate structure
similar to Crystal and New Hope as part of the JWC conservation program.
33
ansgimmisp
C.3.3. City of New Hope Water Rates
New Hope charges its customers based on water use. There is a minimum quarterly fee of
$5.70 for water meter sizes up to and including 1 -inch diameter. This quarterly fee includes up
to 1,000 gallons of water use. Quarterly water use over 1,000 gallons is charged at a rate of
$1.57 per 1,000 gallons (1998 rates). The water rate is based on the volume of water
consumed, and is designed to cover all costs associated with operating and maintaining the
water system. The City reviews water rates every year and will adopt a conservation- oriented
rate structure similar to Crystal and Golden Valley as part of the JWC conservation program.
Water conservation can be achieved through conservation - oriented water rates. The uniform
rates used by the member cities have some effect on water use because all water use is
charged to the customer at a uniform rate. This is better than a decreasing block rate where the
more water that is used, the less that is charged or a flat rate where each customer is charged a
certain rate independent of water use.
Stronger incentives to conserve water include increasing block rates, where the more water
used, the higher the cost per 1,000 gallons, and seasonal rates or surcharges which increase
the cost for water over a base amount during high water use months such as May through
September.
Another option is to bill customers monthly. This is especially important during summer months
when a monthly bill will remind customers of the costs of lawn watering. Switching to monthly
billing would have additional costs associated with it. The member cities should determine if the
benefits from monthly billing would compensate for the additional costs associated with monthly
billing.
The three cities plan to establish conservation- oriented rate structures as part of the JWC water
conservation program. The rate structures will contain incentives for water efficiency, and will
likely contain a consistent base rate in all three cities. Water use rates above the common base
rate will vary among the cities depending on each city's operating and Capital Improvement
budget.
C.4. Regulation
The Energy Policy Act of 1992 stipulates water efficiencies for almost all household water using
fixtures (including toilets, showerheads, and faucets) manufactured after January 1994. Federal
and state plumbing codes have changed so that all new homes and retrofits to existing homes
are required to comply with the new water efficiency requirements. This legislation will have a
positive effect on long -term water demand.
The Cities of Crystal and New Hope both have ordinances for controlling short -term water
demand.
34
sns2mimsP
Following is the portion of the New Hope City Code that relates to short -term water demand:
5.08 Water Sprinkling Ban
5.081 Purpose. The City Council has determined that in certain drought conditions it
may become necessary for the protection of the health, welfare and safety of the
citizens of New Hope to conserve the water supply of the City by imposing a
water sprinkling ban on all residential, commercial and industrial lawn and garden
vegetation. Also, New Hope's contract with the City of Minneapolis for the
purchase of water requires the imposition of a water sprinkling ban at the
direction of the City of Minneapolis. The purpose of this section is to set forth the
nature and extent of the regulations controlling any sprinkling ban imposed by the
Council.
5.082 Resolution Imposing Ban. All water sprinkling bans shall be imposed by adoption
of a resolution at any regular or special meeting of the New Hope City Council.
The resolution shall set forth the duration of the ban, whether the ban shall be
partial or absolute, if a partial ban, whether it shall apply to lawns and boulevards
only or also to gardens, new sod and /or new tree saplings, the days or schedule
when sprinkling will be permitted under a partial ban, and any other regulations
that the City Council deems reasonable and appropriate. Said ban shall become
effective immediately upon the adoption of said resolution.
5.083 Notice of Ban. The resolution imposing the sprinkling ban shall be published
once in the official newspaper of the City, and conspicuously posted in four
places throughout the City. Any deficiencies in this notice requirement shall
invalidate the ban.
5.084 Enforcement. A violation of this section shall be a petty misdemeanor.
However, a first offense shall not result in the issuance of a ticket. The owner,
any occupant of legal age or party responsible for water billing shall be first
issued a warning ticket upon the first violation of the water sprinkling ban. A
warning letter mailed to the occupant of the property or the individual responsible
for the water billing at the violating property shall satisfy the warning notice
requirement of this section. Each act of violation and each day a violation occurs
or continues constitutes a separate offense.
Following is the portion of the Crystal City Code that relates to short-term water demand:
715.29 Restrictions against sprinkling, other limitations of water use. Water customers
and consumers are governed by the applicable regulations promulgated by the
City of Minneapolis as to the limitations in the time and manner of using water
and such other applicable regulations promulgated by the JWC affecting the
preservation, regulations and protection of the water supply. If the City Council
determined that a shortage of water supply threatens the City, the council may by
resolution limit the times and hours during which water may be used for anything
other than in home use during the period covered by the resolution. A daily
penalty will be charged for this violation as provided in Appendix IV. Charges will
be added to that person's next utility bill.
The City of Golden Valley does not have any ordinances regulating water use but, based on
their agreement with Minneapolis, during water supply shortages, they implement water
restrictions in accordance with Minneapolis water restrictions.
35
£405 ?30.1 \WSP
The JWC is currently required to follow the water use regulation and enforcement policies of the
City of Minneapolis, but intends to establish freedom to declare water emergencies and enact
water use regulations through its current contract negotiation with Minneapolis. The goal of the
JWC is to develop a uniform water restriction ordinance for Crystal, Golden Valley and New
Hope and that is coordinated with the City of Minneapolis. As part of the conservation program,
metering capabilities will be improved. Radio -read meters will allow for real time monitoring of
water use and can help detect non - compliant water use during water restrictions.
C.S. Education and Information Program
The member cities of the JWC do not currently have programs to educate their customers about
water use and water conservation. The JWC understands that a public education program will
enhance any of the conservation methods described in this section and plans to coordinate the
education effort among the communities. Once the JWC conservation program is started, city
websites, informational television announcements, brochures, and consumer confidence reports
will be used to provide educational messages related to water conservation and will inform the
public of water emergencies and water use restrictions.
The on -going education program will inform customers of how to increase water efficiency
during everyday use. Education programs can get residents to reduce shower duration, turn off
water while brushing their teeth, and run dishwashers and clothes washers only when they are
full. The program will also encourage residents to invest in low -flow fixtures as a means to
reduce water use. The American Water Works Association (AWWA), and the Department of
Natural Resources have several brochures, bill stuffers and mailers available to educate the
public on water conservation. Examples of various publications available from AWWA have
been included and can be found in a pocket at the end of this report.
Peak water use in the summer months is attributed to lawn and garden sprinkling. An education
program can inform people about how to water efficiently. Educational pamphlets regarding
landscape water use, such as those provided free of charge from the University of Minnesota
Extension Service, can provide residents with the information to change their landscape
watering habits. An example has been provided in Appendix B.
As part of the education program, customers will be informed of their water use priority
described in Section II.E. The JWC intends to establish a "Low Water Alert Test Day" similar to
tornado awareness day, which would institute a mock water shortage.
C.6. Retrofitting Programs
As covered in Part C.4., the Energy Policy Act has changed the efficiency of various water
fixtures manufactured after January 1994. The replacement of existing fixtures will occur
gradually over the years as customers, of their own free will, replace old, low- efficiency fixtures.
AWWA has estimated that 'Based on the combination of fixtures of different ages now in use,
the average 2.63 person household uses about 121 gallons /day for toilets, showerheads and
faucets. This will probably drop to about 55 gallons /day by the year 2026 as the pre -1994
generation of fixtures is replaced by the post -1994 stock."
80F;? 0.nwSP

Fixture replacement could be accelerated if the JWC were to start a rebate program for
replacing old fixtures with new low flow fixtures. Customers would receive a cash rebate or
credit to their account for bringing in an old fixture and a receipt for a new low flow fixture. High
use fixtures such as toilets and showerheads are often targeted in rebate programs. These type
of programs are more effective in older communities which have more high flow fixtures. Since
the JWC has a significant percentage of homes built before 1980, the JWC should conduct a
study to determine if the water savings that could be accomplished through a rebate program
would be worthwhile. Table III -1 shows the potential water savings associated with various
fixture replacement.

Rebate programs are intended to postpone the drilling of new wells or construction or expansion
of treatment plants by reducing the total demand. The cost of the rebate program can then be
spread out over the postponement time. Since there is no future construction planned
throughout the JWC water system for treatment plants or new wells, a rebate program would
probably not be very cost - effective. Encouraging customers to replace fixtures on their own
through education is probably more cost - effective than a rebate program.
C.7. Pressure Reduction
By decreasing the system pressure in a water system, the flow rate (gallons per minute) is
decreased. The Ten States Standards recommends that the normal operating pressure in the
distribution system be approximately 60 psi and not less than 35 psi, and that during fire flow
conditions, all points in the system maintain a minimum pressure of 20 psi. According to the
CYBERNET computer model of the JWC water system, the water system normal operating
pressures range between 45 and 85 pounds per square inch (psi). This indicates that the JWC
is currently operating somewhat above the Ten States Standards' recommended pressures.
Reduction in pressure throughout the system would need to be accomplished by reducing the
water level in the towers. This is not acceptable from a fire - fighting standpoint because
reducing the water levels in the towers would reduce the volume of water available for fighting a
fire.
The only feasible means of reducing pressure to customers is through pressure reducing valves
(PRV). Currently the member cities do not have any plans to install PRV's on the customers'
service lines where pressure levels are high.

PART IV. ITEMS FOR METROPOLITAN AREA PUBLIC SUPPLIERS
A. DESCRIPTION OF THE MUNICIPAL SYSTEM
Parts I.A through I.D and Part 11.13 fulfill the requirements of this section.
B. WATER UTILITY OPERATIONS
B.1. Policies
It is the policy of the JWC to provide high quality water at affordable rates, while assuring that
water supply is adequate to meet the demand of its customers. The water conservation
measures developed through the JWC conservation program will be applied to assure that
water use does not create a long -term negative impact on the Mississippi River.
B.2. Objectives
The objectives of current water utility operations, such as repair of watermain breaks and leaks,
and initiation of a conservation plan are to protect and wisely use the JWC's water resources.
B.3. Standards
Criteria that will be used in system operation for storage expansion, pumping addition, etc., are
developed in Parts I through III. Triggers for implementing short -term demand reduction
measures are based on the storage volumes and pumping capacities of the JWC system, and
water availability from the Minneapolis system. These are discussed in Part II. F. The adequacy
of the existing system (including storage) and associated criteria are discussed in Part I.D.3.
C. CONSERVATION PROGRAM
Parts III.A through D fulfill the requirements of this section.
D. EMERGENCY PREPAREDNESS /CONTINGENCY PLAN
Part II.A and Parts II.0 through H fulfill the requirements of this section.
E. COORDINATION OF PLANNING EFFORTS WITH OTHER SUPPLIERS AND PUBLIC
AGENCIES
E.1. Inter- Community Sharing
As discussed in Section II.C.1, the JWC currently has no interconnections with any adjacent
communities other than the Minneapolis interconnections, which provide all of the JWC's water
supply. The JWC is considering installation of an emergency interconnection to the St. Louis
Park water system, and has also talked with General Mills about the possibility of an
interconnection.
39
805230JAW S P
E.2. Joint Pursuit of Alternative Sources and Protection of Existing Sources
The JWC receives their water from the City of Minneapolis. The City of Minneapolis draws its
raw water supply from the Mississippi River. Should an oil spill or chemical spill occur upstream
of Minneapolis' raw water intake, Minneapolis would likely have to shut down its intake until the
spill passes. Minneapolis has storage facilities equivalent to approximately one day of average
day demand. Therefore, if the raw water intake would have to be shut down for longer than 24
hours, the City of Minneapolis and the JWC would essentially be without water for the remaining
duration of the shut down. Protection of the water supply source by the Joint Powers Water
Commission alone, the Mississippi River, is not feasible because a chemical spill could occur
anywhere for miles upstream of the Minneapolis raw water intake.
To minimize the effect of a possible interruption of water supply due to a spill in the Mississippi
River, the JWC is considering construction of a 16 -inch diameter emergency interconnection
with the City of St. Louis Park. St. Louis Park does not have adequate water supply capacity to
meet both their own maximum day needs and the JWC's maximum day needs, but on a
maximum day condition, St. Louis Park would be able to provide the JWC with 3 MGD.
However, St. Louis Park should be able to provide the JWC's average day demand if the water
emergency should occur during a normal demand period.
The JWC is also considering connecting to more than one adjacent water system. Both
Plymouth and Brooklyn Park have sufficient excess capacity during average demand conditions
and Brooklyn Park has excess capacity during maximum day conditions. The Cities of Brooklyn
Park, Plymouth, and St. Louis Park have all expressed interest in having emergency
connections with the JWC.
The JWC is also currently studying alternative water sources that could be used in the event of
a water emergency.
F. PROBLEMS AND POTENTIAL SOLUTIONS
The elements contained in Part I.D fulfill the requirements of this section.
The JWC does not use groundwater wells as their source of water supply. Therefore, the JWC
will not be required to prepare a Wellhead Protection Plan.
H. IMPLEMENTATION PROGRAM
H.1 Official Controls
As discussed in Part III.C.4, the Cities of Crystal and New Hope both have ordinances for
controlling short-term water demand. Refer to Part III.C.4 for these ordinances.
The City of Golden Valley does not have any ordinances regulating water use but, based on
their agreement with Minneapolis, during water supply shortages they implement water
restrictions in accordance with Minneapolis water restrictions. The JWC plans to adopt common
water regulations following the current water use agreement negotiations with the City of
Minneapolis.
40
8n99in.nwsP
H.2 Capital Improvement Program (CIP)
A copy of the JWC's Five Year Capital Improvements Program (CIP) has been included in
Appendix D. In general, the five year CIP includes inspection, routine repair and replacement of
old and wom equipment, and the upgrading of some equipment. The interconnection with St.
Louis Park scheduled for 2000 is the largest improvement listed in the CIP.
H.3 Impact on the Local Comprehensive Plan
The adoption of the Water Supply Plan will have minimal impact on each member City's
Comprehensive Plan. Since the conservation plan will reduce water use, the volume of water
withdrawn from the Mississippi River (via Minneapolis) will be reduced. Future growth of the
member cities should not be affected by this plan.

The following guidelines were prepared by the Minnesota Department of Natural Resources
(DNR)- Division of Waters and Metropolitan Council. The guidelines are intended to offer
assistance to those communities within the Metropolitan Area with municipal water supply
systems in the preparation of their water supply plans, as mandated by Chapter 186 of the 1993
legislative session Iaws.
These guidelines were produced by the DNR and the Council after input was received from a
technical advisory committee of water suppliers, city planners and resource interests. A public
hearing was held by the Council on November 18, 1993 and a statewide review was solicited by
the DNR in Iate 1993.
Communities with municipal water supplies in the Metropolitan Area will need to submit their
water supply plans as an amendment to their local comprehensive plans by January 1, 1996.
These communities will also need to submit the conservation and emergency contingency plan
components of the plan to the DNR within the same time - frame. Guidelines that the
tiietropodtan Council uses in the review of local comprehensive plan amendments are also
avaiiable from the Council (publication No. 640 -94 -066).
Questions on pars I -III of the plan content guidelines can be answerer by Jim Jao_ s of the DN

P-ART U. EMERGENCY PLANNLNG FOR PUBLIC WATER SUPPLEER,-s
Water emergencies can occur as a result of accidental contamination, mechanical problems,
Power failures, drought, and other natural disasters. The purpose of emergency planning is
to develop emergency response procedures and to identify actions needed to improve
emergency preparedness. In the case of a municipality, these procedures should be in
support of, and part of, an all- hazard emergency operations plan. During periods of limited
water supplies public water suppliers are required to allocate water based on the priorities
established in /Minnesota Statutes 103G.261.
First Priority. Domestic water supply, excluding industrial and commercial uses of
municipal water supply, and use for power production that meets contingency requirements.
Second Priority Water uses involving consumption of less than 10,000 gallons per day.
Third Priority. Agricuituial irrigation and processing of agricultural products.
Fourth Priority. Power production in excess of the use provided for in the contingency plan
under first priority.
Fifth Priority. Uses, other than agricultural irrigation, processing of agricultural p
and power production.
Sixth Priority. Non - essential uses. These uses are defined by NLmesom Statutes 103G.291
as lawn sprinkling. vehicle washing, golf course and park irrigation. and other non - essential
uses.
While initial emergencv responses may include actions to augm

IMM
A. Emergency Telephone List. A telephone list of emergency contacts should be
maintained. The list should include key utility and community personnel, contacts in
adjacent communities, and appropriate local, state and federal emergency contacts. In the
case of a municipality, this information should be contained in a notification and warning
standard operating procedure maintained by the warning point for that community.
Responsibilities and services for each contact should be defined.
B. Current Water Sources and Service Area. The Emergency Response Procedures
should include an attachment that provides concise, detailed information an water sources
and service areas. Quick access to this information may be important in an emergency
situation.
Be sure to indicate the daily production capacity for each source and if the water source
is an emergency, interim, permanent, reserve, seasonal, or other type of source. Water
quality data, maintenance information, or other additional data that may be important in
an emergency should also be included.
1. Description of Ground Water Source(s). Include copies of water Well Records for
each well or a summary of well data. Summaries of well data should include:
Unique Well Number, Iocation, year installed, casing diameter, casing depth, screen
length, well depth, water - bearing formation, pump type and capacity (GPNI).
Description of Surface Water Sources. Include the name of the basic or water
zourse, the number. capacity and age of each pump, size of the basin or low flow
characteristics. and relevant intake information.
Service Ana. A mac of the system should be included as an attachment to the plan
so that it is available for use in the event of an =er aencv. Tne map should indicate
-he locations of treatment piants. water sources (pumps /wells) and major supply lines
thar are part of the distribution system.
C. Procedure for Augmenting Water Supplies. Emergency response procedures must list
ail available sources or .pater that can be used to augment or =lac-- existing sources.
Tae foiiowinq section includes suggestions that should be considered as potential alternate
souses.
1. Interconnections with Adjacent Communities. Plans should identify emergency water
supply sources, inciuding existing and potential interconnections with adjacent
communuies. A list of all private high caoaciry wells that could be available in the
dvent of an emergency should be maintained. In the case of a municipality, this
information should be containers in a notification and warning standard operating
procedure maintained by the warning point for that eommuniry. Copies of
cooperative agreements should be maintained.
7
Note: Be sure to include information on any physical or chemical problems that may
limit interconnections to other sources of water. Approvals from the MN Department
of Health are required for interconnections and reuse of water.
a. Name of interconnecting water systems which supply water to your system:
System Capacity (MGD) Emergency or Daily Use
b. W ater which you provide to interconnected systems:
System Capacity (MGD) Emergency or Daily Use
c. Private water sources Capacity (MGD)
2. Conjunctive Use of Surface and Ground Waters. The feasibilit of conjunctive use of
surface and ground water resources should be considered when both resources are
available. The goal is to use surface water as the primary source when water levels
are adequate. 1 'dmizin" use of surface water will protest and conserve ground
water resources for use in an emergency or when surface water supplies are limited.
Conjunctive water use is especially important in areas where greund water resources
are limited. Plans should discuss the feasibility of conjunctive use incivamz anv
- water quaiiry or av aiiabiliry limitations.
3. - Urernative Sources of Water. :mother option char should be considered when
reasibie. is the reuse of treated water from oump -outs for the containment and
removal of contamination. Often this water is created or can be treated to drinkinz
Water quality standards and could be used in an tmergencv or ev used as part or the
ervdav municiDai supply.
D. Demand Reduction Procedures.
1. Demand Reduction Potential. Information on water demand should be used to
_�vaivate the potential for demand reductions from each customer category. Local
projections of demand reduction potential should be matched with app_ rooriate
measures to achieve reduction goals.
?adopt Short-Term, Demand Reduction, Procedures. Develop procedures for
implementing shot -term reductions in water demand. Initial reductions in water use
can be encouraged by requesting voluntary actions from ail water users. Procedures
for progressively stringent reduction measures should be available for use during
critical water deficiencies. List ail short -term demand reduction measures that are
part of the community conservation plan.
M .
E. Procedures for Water Allocation. Procedures must define how water will be allocated
in accordance with statutory water use priorities during periods of limited water supplies.
Allocation procedures should distribute water equitably within each water use priority and
customer category.
NOTE: Domestic use is defined (MN Rules 6115.0630, Subp. 9), as use for general
household purposes for human needs such as cooking, cleaning, drinking, washing, and
waste disposai, and uses for on -farm livestock watering excluding commercial Livestock
operations which use more than 10,004 gallons per day or one million gallons per year.
Water used for human needs at hospitals, nursing homes and similar types of facilities
should be designated as a high priority to be maintained in an emergency. Local
allocation priorities will need to address water used for human needs at other types of
facilities such as hotels, office buildings, and manufacturing plants. The volume of water
and other types of water uses at these facilities must be carefully considered. After
reviewing the data, common sense should dictate local allocation priorities to protect
domestic requirements over certain types of economic needs.
N water uses by residential and other customers are the lowest water use
priority and should be the first water use subject to allocation restrictions. Quick
responses to restrict non - essential uses during periods of limited supplies will help protect
domestic and economic uses of waxer. Educational efforts to improve efficiencies of
non - essential water uses should be part of long -term conservation programs.
F. Esta blish Triggers for implementing Plan Components. : ggering levels must be
defined for implementing emer responses, inciucung surmiv augmentation. demand

l • Analysis of Previous Supply Problems. In this section list historic and existing water
supply problems. Evaivate the types of problems to determine the potential for
similar problems in the future. If possible try to identify sections of the system that
are prone to failure due to age, materials or other problems. This information should
be used to prioritize preventative maintenance for high risk areas of the system and
also to determine the types of materials (pipes, valves, couplings, etc.) to have in
stock to reduce repair time.
2. Wellhead Protection. Water supply protection is an essential part of emergency
planning. All communities should have a wellhead protection plan prepared Ln
accordance with rules adopted by the commissioner of the Minnesota Department of
Health. Information and assistance on developing a wellhead protection program can
be obtained by contacting the Department of Health, Wellhead Protection Program,
Section of Water Supply and Well Management, 925 S.E. Delaware Street,
Minneapolis, MN 55440.
3. Resource ;vionitorinz. Records of water levels and withdrawals should be maintained
for production wells and reservoirs. The DNR also recommends the installation of
observation wells to assess the short -term and Ion, term resource impacts from
-round water withdrawals. To obtain information on observation well specifications
or to obtain a list of existing observation wells in your area contact the Observation
Well Program Manager, DNR - Division of Waters, 500 Lafayette Road, St. Paul,
MDT 55155 -4032 or call (612) 296 -4800.

PART M. WATER CONSERVATION PLANS FOR PUBLIC WATER SUPPLDMS
Water conservation programs are intended to reduce demand for water, improve the
efficiency in use and reduce losses and waste of water.
Emergency response procedures must include short-term water conservation measures to
reduce water demands when supplies are limited. Long -term conservation measures are an
important part of water resource management and can also help utility managers satisfy the
ever- increasing demands being placed on water resources. Conservation programs can be
cost effective when compared to the generally higher costs of developing new sources of
supply or expanding wastewater treatment plant capacities.
Water users are required (.NLLN Rules 6115.0770), to employ the best available means and
practices to promote the efficient use of water. Laws of Minnesota 1993, Chapter 186, also
requires public water suppliers to implement demand reduction measures before seeking
approval to constrict new wells or increases in authorized volumes of water. Water
suppliers are encouraged to evaluate conservation as a potential alternative to developing
supplemental water sources to meet peak demands for nonessential water uses.
These guidelines describe the elements that must be considered when developing water
conservation plans for short-term emergency procedures and Ion, term programs to improve
water use efficiencies.
A. Role of Conservation. Puns must describe the role that conservation has in managing
community water demands and supplies. Specific quantifiable conservation Goals should
be defined. along with a description of how the achievement or these Qoais will be
measured and monitored.
B. 'Water Conservation Potential. An assessment of water conservation potential should be
done for each customer category using information on water demand in Part I. Evaluate
seasonal demand data. unaccounted for water, and customer water use to estimate
:conservation potential.
C. 'Water Conservation ?rograms. This section must describe short-tern conservation
measures that are available for use in an emergency, and long-.erm measures to improve
,,; ater use ernciencies. Short-term demand reduction measures must be included in the
ernergencv response procedures and must be in support of', - and part or, a community
ail- Hazard emergency operation plan. Specific elements that should be included in the
plan are:
1. yletering. Conservation plans should provide a schedule and describe procedures for
meter r.ading, testing, recaiibration, and repair.'repiacement of defective meters,
including master meters. Plans to achieve 1009c metering should be stated if the
system is not completely metered.
I1
2. Water Audits, Leak Detection and Repair. The volume of unaccounted -for water
should be determined on a regular basis. Unaccounted -for water is the difference
between the volume of withdrawn minus volume sold. Estimating the volume of
water for certain categories of unaccounted -for water can help define program needs
and priorities for on -going system rehabilitation worm.
Gallons
Meter under - registration
Public ur metered use
Potentially recoverable leakage
Other (include unavoidable leakage)
Total unaccounted -for water
(withdrawals- -water sold)
Plans should provide a historic summary of unaccounted -for water losses and describe
existing programs, policies and procedures to minimiz these Iosses. Plans should
specify whether actions to locate and repair leaks are done on a one -time, periodic, or
regular on -going basis. It is important that these programs have adequate funding for
system rehabilitation, maintenance, and repair.
_ . Conservation - Oriented Water Rates. Plans must include the current rate structure
for all customers and provide information on any proposed rate changes. The basis
fcr current price ievels and rates. inciudina cost of service data. and the imtaact
current rates have on conservation must be discussed. Decihiina block. (the more
water used, the cheaper the rate) and fiat (one fee for an unlimited volume of water)
rates should be resuuc:ured to uniform or increasing block rates. Lnco=ratuia a
seasonal rate str.:cture and the benefits or a monthly b ling cvcle should be
zonsidered. Ln conjunction with other demand ruction measures. it is also
- commended that an emergency rate structure that provides even stronger incentives
70 reduce water use be developed and available for imoiemermrion. if necessary.
Regulation.. Plans should include regulations for short -term reductions in demand
and Iona -term imz7rovements in water efficiencies. Ordinances and other regularions
for snort-term demand reduction should have well defined triggering levels for
L Comes of adopted regulations or proposed restrictions should be
included in the plan. Plans should also establish procedures for enforcement and
include penalties for non- compliance with enacted conservation responses and other
restrictions.
12
Note. Regulations can range from prohibiting certain non - essential water uses,
restricting times when specific uses are allowed, establishing consumption limits,
plumbing code changes requiring water efficient plumbing fixrures/appliances,
requiring permits for special uses such as filling swimming pools, and other types of
measures.
5. Education and Information programs. Plans should describe all past, current and
proposed efforts to promote efficient water use. Be sure to indicate whether
educational efforts are on -going and which efforts were initiated as an emergency or
drought management effort. Specific educational materials and notices should be
available for use during periods of limited water supplies when public awareness for
conservation is high.
Educational and information programs include but are not limited to school
curriculums on water resources, direct mailing of conservation information to
encourage voluntary water - saving habits, residential water audits, retrofitting
incentives, public service announcements and other media campaigns. Communities
can also provide demonstration projects for water conserving plumbing fixtures and
landscaping.
6. Retrofitting Programs. Plans should describe any programs to retrofit inefficient
plumbing fixtures (toilets, showerheads, faucets, a nd aerators). The cost of
establishing a program and the potential savings should be evaluated and discussed.
Possible funding sources from water and wastewater revenues and cooperative
Programs with gas and electric utilities should be pursued for demonstration or Iarger
scale projects.
T is recommended that communities develop a long - test plan to retrofit public
buildings. A plan such as this will help promote educationai erorts as wail as
demonstrate fiscal and environmental resDonsibiiirv.
7. Pressure Reduction. Plans should describe any utiliry policy, plumbing codes or
regulations related to distribution and customer pressure control. Be sure to discuss
the use of pressure control as an emergency resonse procure as well as any
ahvsicai limitations that may restrict the use or control.
icer public review the plan should be. formally adopted by the
D. adoption of Plan. d
communityiwater utility. A schedule for impiementing elements of the plan must be
established. Plans must be reviewed and updated every ten ;years.

1993 Minnesota Laws, Chapter 186, requires that all local units of government in the
seven - county Metropolitan Area prepare an amendment to the local comprehensive plan to
address water supply. The new plan would occur as a major plan amendment in the public
facilities plan section, which addresses the "character location, timing, sequence, function.
use and capacity of existing and future public facilities" (Minn.Stat., §473.859). The focus
of plan review will be on the short - and Iong -term impact of water use on the water sup 1v
of the region. , ,
The following guidelines itemize the plan elements required by Chapter 186 in the
Metropolitan Area. These elements often refer to Pans I -M to make the plans consistent
with the law and with the Metropolitan Land Use Planning Act upon which local
comprehensive plans are based.

conformance with the Minnesota Department of Health wellhead protection rules [.Note:
likely to be adopted by the state in late 19931 will constitute this element. Additional
elements on possible joint community protection efforts would be beneficial. (See also
Part IIG2. )
H. L' IPI -ENIE TATION PROGRA.NI
1. Official Controls. Identify the ordinances and reguiations that will be used to achieve
the objectives and the components of the water supply plan. Include the schedule for
preparation. adoption and administration of controls if they do not currently exist.
2. Capital Improvement Program (CIP). Identify the rive -year capital program that will
be needed to accomplish the elements in the plan and the means by which the funds
will be raised. -
3. Impact on the Local Comprehensive Plan. Identify the impact that the adoption of
this water supply plan has on the rest of the local comprehensive plan, including
implications for future growth of the community. economic impact on the community
and changes to the comprehensive plan that might result.
15
The plan must be prepared by the city according to the sequence outlined in Minn.Stat.,
§473.175, and submitted to the Metropolitan Council and adjacent communities for
review and comment by January 1, 1995. The Council will submit the plan to the county
within which the submitting community exists if the community relies on ground water
for supply and if the county has an adopted ground water plan under 2M
§ 1 O3B.255. The Council will finish its review within 90 days or a munially agreed upon
extension, unless it Ends within 10 days of submittal that the plan is incomplete, at which
time the plan would be returned and the review terminated until a complete plan is
submitted. The community officially adopts the plan after it is returned with comments
by the Council.

Following are some important lawn -
awn care
Practices to be considered before reach-
ing for additional feztilizers and pesti
rides. Limiting unnecessary fertilizers
and pesticides can reduce, or possibly
eliminate, potential water contamination
problems from a turf site.
Improving the soil
Before seeding a lawn. consider adding
some organic matter such as peat moss
or compost to either a sandy soil or a
heavier clay soil. (Add 5 - 20 percent
organic matter: for example, I inch of
organic matter to 5 inches of soil equals
20 percent by volume.) This helps im-
prove water and nutrient retention in a
sandy soil and improve the drainage and
aeration chamcteristtcs of a heavier clay
soil. Smaller quantities should be used
on heavier clay soils. Larger quantities
can be used on lighter sandy soils. Thor -
o u ° -h ly mLt ng the cr: a:'c mar,.--r into th

area for =e gMSS plants. An e.'ttensive
root Svste_M occupying larger soil vol-
u:. makkes the grass more capable of
, ` , t:ZStandfng adverse envu-onmental
conditions azid plant stresses.
It is orien t=Pting to add sand to
beatifer clay soils hopL ^.g to improve their
d ra ' inage and aeration a
on chacterristics.
.�.dding only smaall amounts of sand, such
as an inch or two, usually only makes
the condition worse. To electively use
sand to modify a heavy clay soil, san
must be added in quantities of go to 90
percent by soil volume. Mat is, about 8
to 9 inches of sand for every inch of clay
soil. At these high rates, sand particles
begin contacting each other, thereby
opening up larger soil pore spaces. In
most situations, adding that amount of
sand is not practical., The addition of
organic matter is a better alternative.
Alleviating soil compaction on =Istiag='
sites helps improve the turfgrass root -
zone- Core cultivators that remove small
Plugs of soil .from, the ground and depos-
its them on the lawn are available from
many local rental agencies. Several
passes in different directions across the
lawn not only put holes into the ground,
but begins the process of root zone im-
provement. The small soil corrs can be
left on the surface to decompose natu-
rally over the course of a few weeks.
Severely compacted soils may need two
to three treatments per year for the first
two to three years. Also, the degree of
play and traffic that a lawn area receives
determines future frequency of core
cultivation. Cultivation helps improve the
water infiltration c:maracteristics of soli.
thereby reducing runoff from compacted
sites.

Overwatering
Overwatering can cause a number of
problems for the grass plant Soils that
are too wet. particularly in spring and
fall. can predispose the plant to some
fungal disease problems, especially those
associated with the root system. Keeping
a film of moisture on the grass blade for
long periods of tune encourages the
development of some fungal diseases.

Regular mowing with a sharp mower

covers the soil surface. Continually

Grass clippings are a valuable organic
source of nutrients. especially nitrogen
(M. As they decompose. these nutricnts
become available for use by the grass
plant. In fact, yearly nitrogen applica-
tions may be reduced by one -third to
one -half where grass clippings are re-
turned to the turf area. Mulching mowers
and mulching attachments for existing
mowers can reduce the clipping size,
Increasing the rate at which grass clip-
pings decompose. However, mowing on a
regular basis with a sharp mower blade
usually produces clippings that decom-
pose fasly quickly without further size
reduction.
