Protecting. Preserving. Promoting.

The Miami Conservancy

District protects

communities in

Southwest Ohio from

ooding, preserves the

quality and quantity of

water, and promotes

the enjoyment of our

waterways.

The Miami Conservancy Districts Annual Report to the Miami Valley 2010

Miami Conservancy District levees have

withstood every storm event since their

construction nearly 90 years ago. But an

extensive engineering analysis has revealed a

potential vulnerability with the oundation o

the levees.

MCD is doing the engineering analysis to

comply with the Federal Emergency Management

Agencys (FEMA) eort to update ood

insurance rate maps nationwide. For levees to

be shown on the new maps as oering protection,

the levees must protect to the 100-year ood

(a storm event that has a 1-percent chance o

occurring in any given year).

There are eight dierent requirements that each

levee section must pass, says Kurt Rinehart,

MCD chie engineer. Ater extensive studies in

Butler and Warren counties where FEMA began

the process locally, MCD levees have exceeded

most o the standards. One area o concern is

oundation stability or underseepage.

Underseepage is water that seeps through a

dam or levee oundation. Water owing under

pressure through the oundation soils can cause

soil particles to move, creating voids in the

oundation which in turn allow more water to

ow. This situation is called piping because the

ow creates a pipe in the oundation and can

lead to instability and potential levee ailure.

Science was not advanced enough to know

about the eects o underseepage when the

MCD dams and levees were built. MCD has

addressed underseepage at three o its fve dams

and expects to fnish capital improvements at

Englewood and Lockington dams by next year.

Were working to determine how many miles

o levee will need improvements, says Janet

Bly, MCD general manager. The analysis is

under way in Butler, Warren, and Miami counties

but hasnt yet begun in Montgomery County.

Since the oundations all have similar geology,

its likely there could be problem areas in

each county.

Unortunately, i a levee section doesnt meet

every single requirement, FEMA will deaccredit

that levee section. This means cities will have

to enorce oodplain regulations regarding

development, and many homeowners will be

required to purchase ood insurance. Flood

insurance is available to virtually everyone but

currently is optional. (More inormation on

ood insurance)

Its important to note that i a levee section is

deaccredited, that doesnt mean the levee will

ail, Bly says. The probability o a storm

large enough to put this kind o pressure on the

levees remains small, and the risk o piping is

even smaller. Plus, there are ood-fghting steps

that can be taken to urther reduce the risk o

levee ailure. And remember, these levees have

withstood every storm since 1922.

The process

More than 18 miles o levee have been evaluated

in Butler and Warren counties, and another

7.5 miles o levee in Miami County are under

review. FEMA provides only a two-year window

to complete the extensive review and submit

the report including detailed data, drawings and

analyses or each levee section.

Protecting

Dam Safety Initiative

2

In 1999, MCD began a multi-year Dam Saety

Initiative (DSI) capital improvement plan to ensurethe integrity o the dams or uture generations.

The schedule was aggressive and the costs

were conservative.

The plans called or addressing underseepage

water that seeps through a dams oundation

and can lead to dam ailureat all fve dams by

constructing projects along the downstream toes

o the dams.

The plans also included modiying the crest at three

dams by constructing impermeable cut-o walls to

prevent stored ood waters rom seeping through

the embankments. In addition, major repairswould be made to concrete at the dams. Concrete

oodwalls and revetment would be replaced at

several locations.

By the end o 2009, MCD had:

nAddressed underseepage at three o the fve dams

(Germantown, Taylorsville and Human) using

combinations o relie wells, weighted toe berms

and toe drains.

nCompleted relie well projects at the other

two dams (Englewood and Lockington) along with

a weighted toe berm and toe drain project

at Lockington Dam.

nCompleted crest walls at Human, Taylorsville

and Englewood dams. MCD completed crest

remediation projects at Germantown and

Lockington dams beore the DSI in 1970 and 1993,

respectively.

nRepaired concrete revetment and oodwalls

in Troy, Dayton, and Hamilton.

nCompleted concrete inspection at Lockington

Dam.

Final underseepage projectsThe geology at Lockington Dam is more complex

than at the other our dams. The dams oundation

sits on ractured limestone bedrock. The unique

geology required more testingand creativity

to determine a solution to control the underseepage.

While relie wells and weighted toe berms have

been installed to help address the problem, grouting

o our large areas in the oundation east and west

o the spillway also is necessary. Grouting is

expected to start in 2010.

At Englewood Dam, MCD installed additional

relie wells in 2009. A weighted toe berm and toedrains will complete the underseepage control.

Concrete repairs needed at the dams

As part o the DSI, MCD completed a thorough

inspection o the concrete at Lockington Dam. In

2009, MCD hired a contractor to dewater the dams

east conduit to inspect the concrete.

The dams concrete was visually inspected or

cracking and spalling (surace pieces alling o),

and the entire surace was mapped. In addition,

workers drilled into the concrete, taking samples tobe analyzed at a lab.

MCD last inspected the concrete in the 1970s and

subsequently perormed repairs to the concrete.

The 2009 inspection showed a good news/bad

news scenario.

The concrete below the waterline is in excellent

shape, says Kurt Rinehart, MCD chie engineer,

but there are problems above the waterlinea

result o reezing and thawing over the years.

Despite needing repair, there is no immediate

threat to the dam. The deterioration, however, will

continue i not repaired. Repairs to LockingtonDam concrete will be more extensive than in the

past, with some repair work as deep as 2 eet into

the spillway walls. The total estimated cost or

repairs to Lockington Dam concrete is about

$10 million.

Given that the concrete at the dams is about 90

years old, it has held up very well, Rinehart says,

but like bridges and roads and other concrete

structures, repairs are necessary and can be

expensive.

Although MCD hasnt inspected the concrete at the

other our dams, it anticipates similar fndings ateach. MCD will add the concrete repair projects at

the dams to its list o capital improvement projects

that will be needed in the coming years.

Floodwall exercisePractice makes perfect

It would take a massive stormeven larger than

the 1913 oodor the river in downtown Dayton

to rise high enough to ow through the open

levee at RiverScape. Still, MCD prepares or

all possibilities.

Thats why sta members rom MCD, the City o

Dayton and Five Rivers MetroParks installed a

oodwall at the RiverScape plaza last all as part oa ood protection exercise.

When RiverScape was developed, a portion o the

levee was removed, says Kurt Rinehart, MCD chie

engineer. The oodwall provides protection or

that section o the levee should the water ever get

that high. Every ew years, we work with the City

o Dayton and MetroParks to practice installing

the oodwall to keep everyone current on the

procedure.

To install the oodwall, caps are removed rom the

plaza oor area and posts put into the openings.

A backhoe is used to install sections o aluminum

stoplogs. The main oodwall is about 3 or 4 eet

high and about 160 eet wide with another smaller

openingabout 30 eet widewest o the plaza.

The installation takes about three hours.

2009 high water

eventsWhen it comes to high-water events, 2009 wassignifcant not because o the size o the events but

or the lack o it.

Consider this:

nFor the frst time in 16 years, there were no high

water events big enough to cause all fve dams to

store water simultaneously, according to MCD

records.

nIn all, there were 13 storage eventswhen the

pool elevation exceeds the top o the dam outlet

conduitsabout a third less than the 19 events we

average each year.

nNone o the 13 storage events had more than

two dams storing oodwaters at any one time.

nHuman Dam did not have any storage events

in 2009the frst time thats happened in 19 years.

The largest event o 2009 took place February 8-

12, resulting in total peak storage o 10,955 acre-

eet (3.6 billion gallons). The high water event was

triggered by melting snow on February 8 and 9,

ollowed by 0.7 to 1.2 inches o rain alling within

the Great Miami River Watershed on February 10,

11, and 12. The heaviest rainall occurred northo Dayton in Darke, Miami, Logan, and Shelby

counties.

From a fnancial standpoint the lack o high-

water events was benefcial in that we didnt have

a lot o costs in overtime, says Janet Bly, MCD

general manager. In this economy, every little bit

o savings helps.

Preserving

The Miami Conservancy District worked with

DUMP campaign organizers to promote six DUMP

events in the last hal o 2009. Together, the events

collected nearly 120,400 pills, more than 7,850

inhalers and other materials. MCD also worked

with the City o Miamisburg on a prescription take-

back program that collected more than 22,600 pills.

The events were part o an overall eort by MCD to

raise awareness o pharmaceuticals in our streams

and aquiers, and the need to dispose o unwanted

medications without polluting our water supplies.

The United States Geological Survey says watersamples rom across the country and locally are

showing traces o drugs in our rivers, streams,

groundwater and untreated drinking water sources.

All o the prescriptions collected are disposed

o saely and responsibly without impact

to the environment. The DUMP events are

sponsored by MCD and Help Out Ohio, a

local non-proft organization. Check out upcoming

DUMP events in your area.

Water 21st century gold, some say. The Great

Miami River Watershed and its buried valley

aquier are rich with it, yet many people hardly

notice. But thats beginning to change.

In April o 2009, the Dayton Development

Coalition launched its H2Open or Business

campaign eaturing the abundance o good

quality water to attract new, conservation-minded

businesses to the region.

The campaign began with a news conerence hosted

at the Miami Conservancy District (MCD) and an

ad in the Wall Street Journal.

A group o local government, education and

business leadersincluding MCD sta

continues to meet to coordinate eorts that

promote the Dayton Region as water-rich both

in quantity and expertise.

Take-back program keeps drugs out of water supply

DUMP unused medicationsOne in 10 high school seniors admits to abusing

prescription painkillers, oten ound in parents

or grandparents medicine cabinets. Properly

disposing o unwanted medications can be tricky.

They shouldnt be ushed because trace amounts

are being ound in our rivers and streams.

Throwing them in the trash isnt a good option

either. But there is another way. Residents can

take advantage o the Dispose o Unwanted

Medications Properly (DUMP) events.

Already the group has landed the 2010 national

conerence o the Water Innovations Alliance to be

held in Dayton in May. The Alliance is an industry

association ocused on developing and promoting

cutting-edge water technologies and the problems

they solve. The Alliances previous conerence

was held in Chicago in 2009 with more than

300 attendees.

While wein the Dayton Regionhave an

abundant water supply, we dont take it or granted,

says Jim Letwich, president and CEO o the

Dayton Development Coalition. Several local

counties partner with the Miami Conservancy

District to study and report on the sustainability

o this vital resource.

In the uture when local decision makers need to

know how decisionssuch as a new pumping well

might aect the aquier, theyll have a new tool

to help them. MCD has completed contour maps

between Middletown and south o Miamisburg.

It gives us a snapshota picture in time o water

stored, the direction its moving and the speed or

ow, says Mike Ekberg, MCD water resources

manager. We can then compare these baseline

results to uture snapshots to see what changes

have occurred.

The results also can be used as a model to show

eects o certain projects on the aquier.

MCD by the numbers

Sometimes the goal o cleaning up our waterways

can seem overwhelming. How can one person, one

event, one program really make a dierence?

You might be surprised.

MCD successes by the numbers in 2009

120,000 The number o pounds o nitrogen/phosphorus that will be removed over 15 years rom

our waterways through 45 new Water Quality CreditTrading projects unded in 2009.

30, 65, 6 The number o citizen, students andteachers trained as volunteer Miami Valley Stream

Team monitors in 2009. These volunteers monitor

the quality o area streams and waterways.

288 and 945 The number o private-wellowners who took advantage o ree nitrate testing

in the Test Your Well program in 2009, and the total

participants since Test Your Well began in 2007.

Project helps map aquifers futureLets say a business wants to drill three new

pumping wells, Ekberg says, using this baseline

inormation, we can model how it will aect

the aquier.

MCD previously completed map contouring

projects rom New Baltimore (south o Hamilton)

to Middletown. Over time, MCD plans to complete

map contouring along the Great Miami River

throughout the watershed. The next project will

ocus on the area between Miamisburg and Dayton.

$103,750Funds awarded to three communitiespartnering with MCD to implement projects that

protect the regions drinking water. The projects

include innovative practices that prevent runo

by allowing precipitation to infltrate, easing

ooding on streets and sidewalks, and removing

contaminants rom storm water. Another project

involves developing a model to determine the

source water protection area or a citys well feld.

I you ride the Great Miami River Recreation Trail,you knowby seeing all the people you passthat

the trails are popular. But have you ever wondered

just how much use they really get? We have.

There can be a lot at stake with accurate trail

counts. Thats why MCD invested in three trail

counters in 2009 and will be adding two more

in 2010.

Trail counts:

nHelp identiy the months and days o theweek when trail use is highest, allowing MCDto increase trail maintenance during high-use

times and reduce maintenance during lower-useperiods.

nProvide statistics to ODOT to justiy detoursaround state construction projects rather than justclosing the trails or the duration o a project.nIdentiy where the highest and lowest use is,helping to determine i additional or improvedaccess is needed.

nAllow MCD to provide frm numbers abouttrail use to city councils and administrators,helping them understand the impact trails havein their community.

nHelp identiy hour-o-day use trends(commuter versus recreational use).

nHelp bolster grant applications when askingor unds to expand a trail.

Trail counters

Youre being watched well at least counted

Great Miami River Recreation TrailMCD recently provided trail count data to the

City o Dayton to strengthen its Bike Friendly

Community Application to the League o American

Bicyclists, says Hans Landeeld, Recreation

Trail Manager.

MCD installed three counters in May 2009two

in Montgomery County in Dayton and West

Carrollton and one in Warren County in Franklin.

From June through November 2009, more than

25,000 people were counted at the three locations.

The two remaining counters will be placed in

Moraine to provide additional data on trail usage.

Great Miami River Recreation Trail constructionMCD supports the eorts o communities and park

districts to construct and maintain recreation trails

on MCD property. MCD reviews the plans or each

project to ensure it doesnt aect the operation or

maintenance o the ood protection system.

Major gaps are closing rapidly, especially in the

north, on this 90-mile trail, Landeeld says.

PiquaThe City o Piqua partnered with the Miami

County Park District to complete a 2.75-mile trail

extension. The new trail section travels south rom

Lock Nine Park. About 25 percent o the new trail

section is on land owned by MCD.

Concord Township (Miami County)The Miami County Park District completed a 1.8-

mile trail extension north rom Eldean Road. About

1 mile o this extension is on land owned by MCD.

MiddletownThe City o Middletown completed a new 1.9-mile

addition to the trail. Middletown has obtained a

$490,600 Energy Efciency & Conservation Block

Grant rom the Department o Energy to build an

additional 1.8 miles o trail.

You wouldnt ride yourbike without a helmet. Youwouldnt run through anintersection without look-ing both ways rst. So whywould you ever considerkayaking on a river without alife vest or a safety map? Wehope you wouldnt.

Thats why for the past sever-al years MCD has sponsored

the Play It Safe! campaignand free river safety maps.The maps are available forthe Great Miami, Mad andStillwater rivers. Each mapfeatures information aboutriver hazards, how to staysafe on the river, and accesspoints to the river.

When people think o the Great Miami River

Recreation Trail, they oten associate it with ftness

and transportation. But as 160 participants in the

summer River Rides learned, the ride is only hal

the unexploring the charming cities along the

trail can be even better.

Our experience in Troy was eye opening, said Jim

Elking. The downtown area is very interesting,

architecturally and (has a) variety o businesses.

The materials we were given made us aware o so

many things in Troy that we did not know existed.

MCD sponsored the two River Ridesa south ride

eaturing the cities o Miamisburg and Franklin

and a north ride in Troy. The rides were part o theDrive Less, Live More campaign which encourages

drivers to take the bus, bike, walk or carpool

whenever possible.

Each ride was about 14 miles long. Besides

exploring the recreation trail, riders visited

historical landmarks and businesses in the cities.

Two o my riends joined me or this wet and

gloomy ride, said Andi Miner o the Troy ride

which eatured a ew summer downpours. We

had never ridden this path beore and enjoyed it so

much we returned several times over the summer.

MCDalong with the Miami Valley Regional

Planning Commission, the Greater Dayton RTA

and Five Rivers MetroParkssponsored the third

annualDrive Less, Live More campaign in 2009.

Recreation and paddlesports are among the

most popular and astest growing o all outdoor

activities. According to the Ohio Department oNatural Resources, Ohio saw a 43-percent increase

in canoe and kayak registration rom 2003 to 2009.

About 86,000 kayaks and canoes are now registered

in Ohio.

And MCDs latest hand-carried-boat ramp may help

those numbers climb even higher. MCD completed

construction o a hand-carried-boat ramp just above

the Ohio 73 bridge over the Great Miami River in

the summer o 2009. Previously, the closest hand-

carried-boat ramp was in Germantown.

We built the boat ramp downstream o the Armco

Low Dam so users wont have to portage around thedam, says Hans Landeeld, MCD trail manager.

And we picked a location adjacent to the parking

lot that serves the recreation trail. That parking

lot can now be used by cyclists, walkers, skaters,

kayakers and canoeists.

The boat ramp was built with a $50,000 grant rom

the Ohio Department o Natural Resources Division

o Watercrat and has been open since July.

Underseepage story continued from page 1

Levee accreditation does not guarantee the levee

or its perormance, it simply is an indicator o

compliance with certain FEMA requirements.

Addressing underseepage to meet FEMA

standards could require millions or tens o

millions o dollars in capital improvements.

Even more extensive improvements could be

necessary to meet MCDs Ofcial Plan Flood

standards, which are higher than a 100-year

ood. MCD will calculate the cost o improving

levees once all o the levee systems have

been through the levee accreditation process.

These costs would be added to MCDs capital

improvement needs.

The Miami Conservancy District (MCD) has

been a longtime advocate o robust ood

protection inrastructure to ensure public saety

and economic prosperity. MCD supports the

FEMA Map Modernization program to update

ood maps and accurately identiy ooding risks

across the country. However, MCDlike many

communities nationwideaces challenges in

dealing with the levee accreditation process o

Map Modernization. The process requires that

levees meet rigorous compliance standards to be

accredited by FEMA. New FEMA maps will

show accredited levees as providing protection.

I levees are not accredited the maps will be

published as though the levees did not exist.

Some o the challenges include:

nTight deadlines and unexpected costs to

evaluate the levees and certiy that compliance

standards are met.

nInadequate time and unds to complete

repairs to levees beore the ood insurance

maps are fnalized.

nPotential economic impacts new ood maps

could have on the communities MCD protects.

Levee owners have been given only a two-year

window to complete the extensive evaluation o

their levees. Miami Conservancy District sta

is working hard to assure we meet the two-year

deadline or levee evaluation submittals. FEMA

has not allowed any time or levee repair.

Reducing the risk o ooding is our primary

goal. Preventing oodingby allowing time

or levee repairsseems a better approach

than simply requiring that property owners

purchase insurance.

Some Congressmen agree. Proposed legislation

in both the House o Representatives and

Senate would suspend ood insurance rate

map updates in areas where levees are being

repaired. Another bill in the House would allow

FEMA to temporarily extend the deadline or

reaccreditation i a good aith eort to upgrade

a levee to the accredited level is being made.

Levee Accreditation Process

To even begin the Levee Accreditation process,

levee owners must provide FEMA inormation

(including a Maintenance, Operations and

Inspection manual; maintenance records; and

levee height estimates) that would lead FEMA

ofcials to expect the levee can be accredited.

Below is a brie diagram o the process and

potential outcomes.

nNo changes

nCities must enorce

oodplain regulations

nFlood insurance required

Provisionally Accredited Levee (PAL)

2 years to submit more in-depth

inormation plus geotechnical borings
