INTRODUCTION
The 2016 Cedar and Dixon Counties (CDC) Multi-Jurisdictional Hazard Mitigation Plan (HMP) is an
update to the plan that was adopted by CDC and the Lewis and Clark Natural Resources District (NRD) in
October 2010. This HMP includes two primary sections: the Regional Hazard Mitigation Plan and the
Participant (i.e. County, Municipality, and School District) Sections. Participant Sections include similar
information to that provided in the Regional section, but also specific information for the communities,
including the following elements:

Cedar and Dixon Counties Multi-Jurisdictional Hazard Mitigation Plan ♦ March 2016
LOCATION AND GEOGRAPHY
The Lewis and Clark NRD is located in northeast Nebraska, covering 1,467 square miles, and includes 20
communities a number of which are unincorporated. The NRD serves a total population of 16,572
throughout portions of Cedar, Dixon, and Knox Counties.
Figure LCN.1: Map of the Lewis and Clark NRD

CLIMATE
For the NRD area, normal high temperatures for the month of July is in the mid-80s and normal low
temperatures for the month of January is in the lower teens. On average, the NRD gets around 28-30 inches
of rain and 31-33 inches of snowfall per year. The following table compares these climate indicators in
Cedar, Dixon and Knox County with those of the entire state. Climate data are helpful in determining if
certain events are higher or lower than normal. For example, if the high temperatures in the month of July
are running well into the 90s, then this indicates extreme heat events, which could impact vulnerable
populations such as the very young and the elderly if cooling areas are not provided.

*Precipitation includes all rain and melted snow and ice.
TRANSPORTATION
The major transportation corridors in the NRD include U.S. Highways 20 and 81, and Nebraska Highways
12, 57, 84, and 9. Highways 12 and 57 were noted as being of greatest concern. Several chemicals are
known to be transported regularly across the NRD including carbon dioxide, chlorine, lime, ferric chloride
and sodium chlorite. The Nebraska Northeastern Railroad Company has a rail line that travels through
southeastern portion of the NRD service area. Transportation information is important to hazard mitigation
plans because it suggests possible evacuation corridors in the community, as well as areas more at risk to
transportation incidents.
DEMOGRAPHICS
It is estsimated that the Lewis and Clark NRD serves a population of 16,572 over three counties. However,
the NRD does not collect information on age, or other demographics of their population, nor does the U.S.
Census Bureau recognize the NRD. As a result, there is no additional population data for the NRD as a
whole. For information regarding population data in Cedar and Dixon Counties, please refer to the specific
jurisdiction participant sections or to Section Three: Demographics and Asset Inventory.
NRD PROJECTS AND PARTNERSHIPS
Cedar Knox Rural Water Project
The Cedar Knox Rural Water Project was started in 1977 mainly due to the water quality in northern Cedar
and Knox counties. Grounad water was high in sulfates and hardness. Additionally, some areas also had
quantity problems. A suitable ground water source within the service area could not be located. So the
Lewis and Clark Lake is the wtaer source for the project, and a surface water treatment plant was purchased
from the then bankrupt Devils Nest Development.
Work on the distribution system and refurbishing of the treatment plan began in 1981, and the first water
went out to the customers later that same year. The project now serves over 750 servcies concections, four
villages, three housing subdivisions, Gavin’s Point Dam offices and campgrounds, Lakeview Golf Course,
and Lewis and Clark State Recreation Area. A map of the service area is on the next page.

NSWCP and NRD Cost Share
The NRD has an agreement with the Nebraska Department of Natural Resources to administer the Nebraska
Soil and Water Conservation Program (NSWCP) within the area. An annual appropriation of over $100,000
is available through the program for conservation practices within the district. The program provides
reimbursement costs for the installation of the following practices listed below. In addition, the NRD has
its own cost share program of between 50 and 65 percent to supplement the state program.

Flood Prevent and Control
The NRD has been active in providing flood control structures and has had three Resources Development
Fund Control projects financed in the past by the Department of Natural Resources. These projects are:
Antelope Creek (1986), Aowa Creek (1980), and Powder Creek (2003). In addition, the District has helped
counties finance road structures to replace high maintenance bridges with flood controlling dams. Payment
of up to 50 percent of the cost is provided if 75 percent of the drainage above the site is under proper land
treatment.
The Aowa Creek PL-566 Watershed project is complete with 50 grad stabilization and flood control dams.
The project is 55,000 acres in size and with the assistance of the Dixon County Board has already provided
benefits to the communities of Newcastle and Ponca. The Antelope Creek Project, now the Chalkrock
Wildlife Management Area, controls drainage of 11,500 acres besides providing recreation on land donated
by area farmers for flood control.
FUTURE DEVELOPMENT TRENDS
The NRD anticipates an addition for the main office in Hartington in 2015. Additional water users will be
added to the Cedar Knox Rural Water Project as well.
PARCEL IMPROVEMENTS AND VALUATIONS
Please refer to Section Three: Demographics and Asset Inventory for parcel improvements, valuation, and
discussion across the planning area.
CRITICAL INFRASTRUCTURE/KEY RESOURCES

There is no record of previous dam failure with the NRD. A dam failure, particularly of a high hazard dam,
has the potential for significant losses due to flooding including economic impacts, loss of life, crop loss,
and business and housing damages.
All dams are inspected on a regular basis and after area flash flood events. If problems are found during an
inspection, the proper course of action is taken to ensure the structural integrity of the dam is preserved. In
the event that dam failure is imminent for a high hazard dam, the Emergency Action Plan (EAP) for the
dam governs the course of action.
Implemented mitigation projects:
 Dams are inspected regularly and maintained
 County emergency operations plans are available
 EAPs available for high hazard dams
Identified mitigation projects:
 Continue regular dam maintenance and inspections
Drought
Drought was identified as a top concern for the NRD. During the summer of 2012, an exceptional drought
formed for a large portion of the state, including areas across the NRD. The local planning team indicated
that this drought showed areas of concern, and that in general a drought would bring water conflicts due to
shortages of groundwater supply. At this time, the water supply is sufficient, but if a long, exceptional
drought was to form, it would create issues across the NRD. The NRD is currently working on an Integrated
Water Management Plan with the Department of Resources.
 Partnering with DNR on an Integrated Water Management Plan
 Expand water storage capacity / Emergency water supplies
 Drought monitoring plan and procedures
 Groundwater / Irrigation / Water conservation management plan and practices

Flooding
Flooding can have significant impacts on NRD recreational and watershed structures as well as causing
stream bank erosion. It can also impact the rural water project in Cedar and Knox counties. None of the
NRD facilities have sustained damage from flooding.
The flood of 2011 on the Missouri River and the resulting releases from Gavins Point Dam caused panic
among residents close to the river. This lead to widespread sandbagging operations in areas that were
ultimately not affected by the flood. The 2011 flood did erode some bank areas and caused some seasonal
cabins and outbuildings to fall into the river. Additionally, flood waters flooded some crop land and caused
it to be unproductive for a couple of years following the flood. The Missouri River was closed to all boat
traffic from Memorial Day through Labor Day causing economic loss and a reduction in those who frequent
the area on weekends for recreation, fishing on the river, and camping in the campgrounds.
 County emergency operations plans are in place
 Aowa Creek Watershed Project was completed in 2004, which provides effective flood control off
81 percent of the drainage area above Ponca
 Stream bank stabilization, grade control measures, and channel improvements
 Flood-prone property acquisition
Severe Winter Storms
The NRD is primarily concerned with this hazard restricting access to the rural water facilities as well as
power outages. Brief power outages have occurred in the past and blizzards and heavy snow events have
impacted the ability to access rural water facilities.
 Back-up power generators are available for rural water project including one for Booster #2 and a
portable unit is available
 Installation of windbreaks/living snow fences
 Obtain or replace back-up power generators for critical facilities
Tornados
Tornados have impacted the NRD in the past and the local planning team especially noted the Coleridge
tornado as an example. The direct impacts that have occurred from these tornados include a loss of
windbreaks and farmsteads. It was stated that the toilet facilities at Buckskin Hills and the dam risers in
Dixon County have been damaged by tornados in the past.
 Data is regularly backed-up at the NRD
 Back-up power generators are available for rural water project including one for Booster #2 and a
portable unit is available
 Construct a safe room
 Improve emergency communications
14
Grass/Wildfire
Wildfire is a hazard of concern identified by the NRD. Excessive vegetative growth along bluff areas in
Cedar County has been identified as an area of concern were it to catch fire and spread. Several fire districts
are located across the NRD that would respond to a wildfire were it to occur. The local planning team did
not identify any previous significant wildfire events that impacted the area.
 Fire districts available for wildfire fighting
 County emergency operations plans are available
 Hazardous fuel reduction to reduce fire intensity, improves fire suppression effectiveness, etc.
 Complete a wildfire protection plan
 Fire prevention program
GOVERNANCE
The Lewis and Clark NRD is governed locally by a group of 11 elected Board of Directors and entrusted
with a broad range of responsibilities to protect and enhance Nebraska’s many natural resources. The NRD
serves both incorporated and unincorporated areas within their jurisdiction and have the capability to
financially and administratively assist villages, cities, and counties with mitigation actions, most commonly
flood control and drainage improvements.

CAPABILITY ASSESSMENT
The capability assessment consisted of two main components: a Capability Assessment Survey completed
by the jurisdiction and a review of local existing policies, regulations, plans, and the programs. The survey
is used to gather information regarding the jurisdiction’s planning and regulatory capability; administrative
and technical capability; fiscal capability; and educational and outreach capability.
The NRD does have the authority to levy taxes for specific purposes and to issue general obligation bonds
to finance certain projects. The NRD also regularly engages in public education and information programs
related to hazard mitigation in the area. Also, the NRD routinely works with other counties, cities, and
villages within their jurisdictional boundaries.
