Resolution 13 -
May _, 2013
Commissioner introduced the following resolution and moved its adoption:
RESOLUTION ACCEPTING EMERGENCY WATER SUPPLY PRELIMINARY DESIGN
AND FEASIBILITY STUDY; DIRECTING STAFF TO PROCEED WITH
IMPLEMENTATION
WHEREAS, the Joint Water Commission (JWC) is a joint powers entity
authorized by Minnesota Statute 471.59 consisting of the cities of Crystal, Golden
Valley, and New Hope, initiated in 1963; and,
WHEREAS, based on this agreement, the three cities built their water distribution
systems to be interconnected without reference to city boundaries; and,
WHEREAS, the JWC has an ongoing long-term water purchase agreement with
the City of Minneapolis water utility and intends to continue that relationship; and,
WHEREAS, the JWC continues to have concerns regarding the reliability of the
Mississippi River as the sole water supply source for the City of Minneapolis and its
customers; and,
WHEREAS, in 2009 the JWC and, separately, each of the three member cities,
adopted a Water Supply, Emergency and Conservation Plan to comply with Minnesota
Statute 473.859, and said statute requires the JWC and the three member cities to
identify and develop an emergency source of water supply; and,
WHEREAS, the JWC has identified groundwater from the Prairie du
Chien/Jordan aquifer to be a viable alternative water supply on an emergency basis;
and,
WHEREAS, legislation was passed during the 2004 legislative session
authorizing the JWC to drill wells to meet the needs of the three member cities on a
case-by-case basis; and
WHEREAS, at the direction of the three City Councils at the May 7, 2012
Tri -Council meeting, the Emergency Water Supply Preliminary Design and Feasibility
Study was prepared; and,
WHEREAS, the study sets forth recommendations for siting of wells, cost
implications and alternatives for implementation of an emergency water supply.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of
(Golden Valley, Crystal or New Hope), Minnesota:
1. That the Joint Water Commission develop a Capital Improvement Program to
implement an emergency water supply.
2, That the Joint Water Commission retain engineering and other professional and
contractor services to implement and construct an emergency water supply.
Adopted by the City Council of the City of (Golden Valley, New Hope or Crystal),
Hennepin County, Minnesota, this — , day of May, 2013.

From: MN Department of Natural Resources m iito:dnr.0 ates.mndnr. ov

To: Tracy, Bert
Subject: Community Water Suppliers Drought Response
www.mndnr.gov
The Department of Natural Resources is contacting Minnesota's community public
water suppliers in follow-up to last fall's communication about drought response actions.
Dry, hot conditions in both 2011 and 2012 have posed challenges to many public and
private water supplies. Much-needed winter precipitation has helped alleviate drought
intensity across most of the state, but additional spring rain is needed to provide
recharge to our aquatic systems.
As of April 30th, the U. S. Drought Monitor displayed that in Minnesota:
91 % of the state is Abnormally Dry or worse
46% is experiencing Moderate Drought or worse
15% remains in Severe Drought
In preparation for unknown weather patterns in 2013, the DNR encourages water
suppliers to do the following three things:
�. Review the state's Drought Plan Matrix (on the DNR website; a link to the site is
embedded below)
2. Implement the drought response measures in your public water supply plan, if
you have one, and the applicable steps in the Drought Plan Matrix for water
suppliers
3. Promote water conservation to your customers and clients
1. Review Minnesota's Drought Plan Matrix
Minnesota has a statewide Drought Plan that provides a framework for responding to
droughts. It is an important resource for all public water suppliers. It outlines five
drought phases, which correlate to the U.S. Drought Monitor. It identifies the actions
public water suppliers must take as each drought phase is reached.
At this point, 91 % of Minnesota is experiencing some level of drought, with notable
portions of the state in the moderate and severe categories. All public water suppliers
should be aware of their planned drought response, and the majority should begin
implementing specified actions contained in the Drought Plan.
2. Implement Drought Contingency Measures and Prepare Communications to
Users
If you serve over 1,000 people, you should have a Water Supply Plan that includes
sections related to your drought preparedness, drought response and water
conservation programs. Now is the time to review those sections and implement the
planned actions. If you do not have a Plan, you can still ask your customers/clients to
reduce their use of water and you can implement at least basic conservation measures.
91 % of Minnesota is in at least the Drought Watch Phase. That means public water
suppliers need to be providing conservation information to their customers and
requesting them to implement voluntary measures to reduce water use. Please work on
preparing these communications and sharing them with your customers throughout the
coming months.
Just over 15% of the state is at the Drought Warning Phase. In accordance with the
Plan, suppliers implement the water use restrictions covered in their water supply plans,
and implement water use reduction actions with a goal of reducing water use to 50%
above January levels.
3. Promote Conservation
Water conservation will reduce the demand placed upon groundwater and surface
water resources, and on municipal water supply systems. DNR encourages you to
actively communicate with your customers on the importance and benefits of water
conservation.
Spring is an excellent time of the year to affect the summertime practices of your
customers and to guide them to the benefits of conservation. Given the severity of the
fall drought in both 2011 and 2012, communities all recognize the value of protecting
water supplies for the long-term. Additionally, communities may undertake water audits
and leak detection, which often leads to significant reductions in water loss as well as
cost savings.
Drought highlights the challenges we face as water supplies are stressed and recent
increased media and public attention has been focused on water resources, all across
the state. The need for clean and robust supplies exists at all times, and underscores
the need for planning for long -tern sustainable water supplies for all communities and
homes.
More Information and Contact Resources
Visit the DNR website to find the latest information and fact sheets on the drought.
Additionally, please direct specific questions to:
Princesa VanBuren Hansen, Water Use Specialist, princesa.hansen(?_state.mn.us,
651-259-5731
Greg Spoden, State Climatologist, re o .s oder state.mn.us. 651-296-4214
The DNR seeks to maintain an open partnership with you in providing safe, reliable
drinking water sources to the citizens of our state. When facing the challenges posed by
a drought, we must work together to ensure the public understands the implications of
their individual actions and how everyone can take steps to ensure we are prepared to
adapt in case dry weather patterns persist. We appreciate your participation and
engagement in achieving these goals.
