From: Judy Hn|nt Deputy Clerk/Finance Director
Re: 2010 Preliminary Budget Adjustments
The proposed 201O General Fund Revenue budget ix$4,17O,4D6. The proposed 2010 General Fund
Expenditure Budget is$4,162,833. There isa surplus of$16,453|n revenues over expenditures inthe
proposed budget.
The general levy and debt service levy that was approved at the September 8, 2009 Council Meeting and
certified to the County and sent in for approval to the State of Minnesota is $3,778,596 for the general
levy and $S0I,080 for the debt service levy. Total proposed levy amount ix$4,J80,590. The levy
amount results in an estimated 17% increase in levy over 2009 and a 23.3% estimated in tax rate over
2009. The dollar amount of increase per year is estimated to be between $55.19 for a $100,000 home
tn$437.52 for o$760,U00home. For a home valued at$200,0O0tn$ZSO,000 results inanestimated
$110.88tn$138.40 increase in tax per year.
For every $1OO,00O decrease 'in levy, the tax will decrease $Z3 to$29 for a residential home valued at
$200,000 to $250,000. if Council desires to have a zero dollar increase in tax, the levy will need to be
reduced by approximately $472,000.

2010 Preliminary Budget Adjustments
Page 2
There are several areas of the expenditure budget that could be adjusted to achieve a reduction in the
tax levy without having a major impact on City operations or capital purchases.
The hire date of the new Finance Director could be delayed by 2 to 4 months. The current budget
reflects a new Finance Director for 8 months in 2010. If the position is filled by a person that is already
in a Finance Director position or is hired from within, the person should have the basic knowledge
needed for the position; therefore, 2 to 4 months of training should be sufficient. The savings would be
$17,290 for 2 months or $34,580 for 4 months.
A decrease in the amount we transfer out for street reconstruction, storm sewer replacement /renewal,
and capital purchases could be reduced without affecting the improvements or purchases outlined in
the draft GP. Suggested possible reductions are:
Transfer to Street Reconstruction Fund - decrease transfer $185,000
Transfer to Storm Sewer Renewal /Replacement Fund- decrease transfer $50,000
Transfer to Budgeted Projects:
Decrease Sealcoat -we have funds remaining from 2009 $120,000
Decrease PD Vehicles -we have funds remaining from 2009 $9,500
Decrease PW Vehicles -we have funds remaining from 2009 $10,000
Decrease Computers -we have fund remaining from 2009 $3,500
Total possible adjustments to transfers out $378,000
FYI —Council has the option of reallocating the unallocated funds in the Budgeted Projects Fund to make
up for the reduction in transfers from the General Fund to the Budgeted Projects Fund, i.e. you could
reduce the transfer $9,500 for PD vehicles and then reallocate $9,500 from the Budgeted Projects Fund
unallocated to the PD vehicles. As of August 31, 2009 there is approximately $100,000 in unallocated
funds with the Budgeted Projects Fund.
Total budget adjustments to achieve -0- tax increase:
Revenues /Expenditure Surplus $16,450
Adjustments due to new information- Revenues $5,000
Adjustments due to new information - Expenditures $36,100
Expenditure adjustment for new hire in finance $34,580
Expenditure adjustment for transfers out 5378,000
Total adjustments to achieve -0- tax increase $47 0,,130
I have not received any additional information from Washington County on taxable values.
Attached is a tax impact worksheet indicating the tax impact of the proposed 2010 total levy that was
submitted to the County in September and a tax impact worksheet indicating the tax impact if the
suggested budget adjustments of $470,130 are implemented and the tax levy is reduced by the amount
of the adjustments.
There will also be adjustments to the expenditure budgets forthe Utility Funds for the change in rates
for employee health, life and dental insurance and to adjust for the MCES billing amount received from
Met Council for 2010. Utility Fund revenue budgets for customer collections will also be adjusted to
reflect these changes.

Subject: OPH Emerald Ash Borer Management Plan
Attachments: OPHEAB09.doc
Eric -
I have updated the proposed OPH EAB Management Plan to include info.
from various workshops /update sessions I've attended in the past few months, website updates
and the draft EAB Management Plan for the state of MN. I have also included the number of
ash trees planted in the city parks. I have estimated costs for removing 5% of the ash each
year in anticipation of EAB arriving in the area. I also have included estimated costs for
injecting individual ash trees. There is not much info. on disposal or utilization yet,
other than chipping for mulch and energy generation. As EAB becomes more widespread, there
may be opportunities for partnering with neighboring communities on some management work.
Cost -Share Grant opportunities have just been announced by the MN Dept. of Agric.. I have
requested an RFP and application form for a Planning and Preparedness Grant. Not sure yet if
OPH will qualify, since the city already has a boulevard tree inventory and has a good start
on a management plan, but I'll take a look at the RFP and application when I receive it. Let
me know if you have any questions regarding the management plan.

City of Oak Park Heights
Emerald Ash Borer Management Plan
To: City Administrator
City Council
From: Katharine D. Widin, P1r.D.
Plant IIealth Associates, Inc.
Forestry Consultant
1016/09
Purpose:
By implementing the provisions in this management plan, the City will take a
proactive and informed approach to management of the ernerald ash borer (EAB) and
help prepare city staff, council, commissions, and residents for the time when it is
confirmed in Washington County. The expected loss of ash trees in the City due to this
insect will have an economic impact on both the city and its residents. It will also have
an effect on property values, quality of life and the environment. The goal is to buffer
these impacts by implementing current management strategies and options regarding what
is known about this pest and its management in other states. Taking a proactive approach
will enable the City to address public and private needs in an efficient and effective
manner.
Introduction:
Emerald ash borer (EAB) is a non - native insect pest introduced to North America
in the 1990's from Asia, probably in wooden shipping; materials. It was identified in
Michigan in 2002. It has killed millions of ash trees in the state of Michigan and has now
spread to the states of Indiana, Ohio, Maryland, Virginia, West Virginia, Illinois,
Missouri, Pennsylvania, New York, Wisconsin, Minnesota, and Kentucky, as well as the
Canadian provinces of Ontario and Quebec. All species of ash appear to be susceptible.
In Minnesota, green ash is the species most commonly planted in urban and suburban
landscapes and it also occurs naturally in native woodlands. White ash is occasionally
planted and occurs naturally in native woodlands. Black ash is a species primarily found
in wet areas, such as black ash swamps in northern Minnesota. Site and soil moisture
factors do not seem to make much difference in terms of a tree's susceptibility to EAB.
Current evidence from Michigan and Ohio show that once EAB becomes established it
takes about five years to infest and kill the majority of the ash trees in a community.
EAB can fly only a few miles on it's own and natural spread is about 4 miles per
year. It can spread much faster by the movement of infested ash wood such as bark - intact
fogs and firewood or in living, infested ash trees.

OPH EA13 Management Plan — 10109 — 2
In April 2009 TAB was found near Victory, Wisconsin, south of LaCrosse, about
one mile from the Minnesota border. LAB was found in St. Paul May 13, 2009. About
70 trees, which were known to be infested, were removed in June 2009. Quarantines
prohibiting the movement of ash trees, logs, bark- intact lumber and firewood have been
enacted for Houston, Ramsey and Hennepin Counties. Removal of infested trees is
considered management only, not eradication. Experts agree that we will not be able to
eradicate this insect, only manage it to slow its spread and the ensuing damage. EAB is
difficult to discover in the early stages of infestation.
Trees can be protected by several types of systemic insecticides; however these would
have to be repeated every 1 -2 years, depending on the material used. Insecticide treatments
should only be used on high value ash, in good condition, which provide important landscape
functions and add to property value. Trees to be treated would most likely be in the growth
category of 10 -20 in. trunk dbh (diameter at breast height). Occasionally, larger specimen ash
would warrant treatment; however, protection of large ash with systemic insecticides has been
more variable in distribution and efficacy than treatments on smaller diameter ash. Infested trees
( <35% canopy symptoms) can also be treated with systemic insecticides with some degree of
success. It is important to understand that insecticide treatment is a management tool. 'I"reatmnent
can save trees longer in the landscape; however, it does not guarantee long -terns survival and
treated trees may still be removed under local, state or federal mandates. Current
recommendations are to only treat ash trees within 15 miles of a known infestation area. At
present, the closest know infestation to Oak Park Heights is in a neighborhood of St. Paul, just
east of the intersection of Hwy. 280 and 1 -94. OPI I is a little farther than 15 miles out from that
infestation area; however, other communities within Washington County are within that 15 mile
radius.
Detection of emerald ash borer in St. Paul has heightened the awareness of this
insect and, hopefully, will mean early detection of EAB in communities in Washington
County. If LAB is managed it can slow the spread of the insect to and through
communities and allow municipalities some time to plan and react. The presence ofthis
insect has not yet been cons armed in Washington County; however, it may already be
present. Therefore, the city should take steps to prepare for an EAB infestation. If
properly owners of public and private lands work together, it may be possible to slow the
spread of EAB, which would give the community more time for the removal and
replacement of ash. Planning for EAB management should begin now.
What Oak Park Heights Can Do:
To slow the spread of EAB it is important to limit the amount of phloem (tissue tinder the
bark through which sugars move) which is available to be utilized by LAB larvae as they
develop in the tree. Based on information and experiences with LAB in other states, the
city has several choices for dealing with the existing ash trees which will be infested and
killed by the emerald ash borer:
Page 11 of 18
01 CAB Maiiagetueut Plan — 10/49 — 3
1. do nothing and remove trees as they die - this option would work for a city
which knows the number and locations of ash within the community and has the funds to
remove all dead /dying trees within I or 2 years (estimate 700 ash (600 blvd., 100 parks)
rr ave. removal cost of $600. = $420,000.)
2. do a structured removal of non - infested trees — this option would prioritize
and spread out removals over a number of years by taking out the ash in poor locations
(under power lanes, restricted rooting areas), ash in poor condition, such as those with
defects, decay, or a lot of upper branch dieback. The draft EAB management plan of the
Minn. DNR suggests removing 5% or more of the existing ash each year to reduce the
amount of susceptible ash within the city. For OPI -1, removal of 5% of 700 trees per year
equals 35 trees a ave. removal cost of $600. = $21,000. Removal of ash trees ahead of
EAB arrival will also require education for residents (newsletter, open meeting, seminar,
etc.).
3, treat all ash with systemic insecticides - the city must know the number
locations of ash within the community to make a decision based on economics since the
treatments would have to be repeated every 1 -2 years, depending upon which method is
chosen. Ash insecticide treatment would cost approx. $9. per diameter in. for trunk
injection, e.g. $180. for a 20 in. diameter tree. lnjection would have to be repeated every
2 years for an unknown period of time.
4. a combination of structured removal of ash trees and insecticide
treatment of selected valuable ash -- the city might decide to treat valuable
ash of good size, form and condition on boulevard rights -of -ways or in parks, The city
might also share the cost of treating high value boulevard trees with adjoining propert
owners, or allow the adjoining property to pay for treatment of boulevard ash if they wish
to keep the tree. Record - keeping would be a challenge for this option.
EAB Management Plan
An EAB Management flan, which is a realistic reflection of the city's resources
for battling EAB, should be adopted by the Parks Commission and City Council. The
basics of most EAB Management Plans are to reduce liability and economic impacts to
the community from trees killed by this insect. Any EAB Management Plan is subject to
periodic revision as new information about EAB becomes available. This plan is also
subject to change should state or federal policies dictate.
Administration:
A staff member in this community, , should be responsible; for
implementing and tracking the provisions of this plan.

Communication: The City Administrator, Dept. Heads, City Council, Parks
Commission, (and any other entities identified by the city), will receive periodic updates
through normal channels. All media relations will follow normal city protocol.
Detection: Education of staff, residents, people who are knowledgeable about trees in the
community and can educate peers, site visits /telephone calls by the Arborist, who is a MN
Forest Pest Hirst Detector. The Arborist will work with the Minn. Dept. of Agric, and the
DNR re: any populations of EAB which are found in the city.
Ordinance: The city should update its ordinance to deal with important insect and
disease pests, other than Dutch elm disease and oak wilt, which can also lead to the
requirement of tree removal. Specifically at this point such a pest would be the emerald
ash borer.
Boulevard Trees and Trees on Public Property Other Than Parks:
I . The City will begin by enacting the policy of excluding the planting; of any new
ash trees on public property and boulevards.
2. The City has an inventory of ash trees on boulevards and other public rights-of-
way, and city property
3. Ash trees which are in poor condition, with poor form, defects, decay and those
frequently pruned severely due to proximity to power lines, should be removed to
reduce the available host material which is of poor quality and /or condition.
4. Ash trees removed should be replaced with trees of a variety of species
representing a variety of plant families (see recommended tree species list).
5. Plantings will occur in the spring and late summer /early fall per the current
planting procedures of the city. The City has a Tree Planting fund.
6. City should decide if they want to treat any existing ash on the boulevard or
on public property with systemic insecticides (See "Insecticide 'Treatment
Options" in the Appendix)
Park Trees:
1. The City will also enact the policy of excluding the planting of any new ash
trees on park land.
2. The Arborist has completed a count of ash trees in active areas of parks
3. The City should remove ash trees in parks which are in poor condition or
which have major structural problems or defects.
4. Ash trees in wooded areas along trails will be removed if they would become
a risk to a trail user or structure once dead from EAB.
5. Specimen ash trees which are removed should be replaced with a different
tree species. If multiple trees in a park are replaced, a variety of tree species,
representing different plant families, should be planted (see recommended
tree species list).
6. Plantings will occur in the spring and late surnmer /early fall per the current
planting procedures of the city. The City has a 'free Planting; fund.

7. In wooded areas of public property, natural regeneration will play a
significant role in reforesting park land. Invasive non - native plants should be
monitored and managed, if necessary, to maintain a native woodland in good
condition.
8. City should decide if they want to treat any existing ash on the boulevard or
on park properly with systemic insecticides (See "Insecticide Treatment
Options" in the Appendix)
Trees on Private Property:
1. The forestry consultant will be available to provide information about FI'AB
identification and management via telephone calls and site visits to residents.
The forestry consultant will also regularly post information re: EAB on the
city website, in the city newsletter, and, occasionally, in articles for local
newspapers.
2. Owners of private property will be responsible for removal of infested ash
trees on their property. Whether this is required by the city as a measure to
reduce the incidence of IAB through sanitation, will depend, in part, upon
what stage the infestation is at in the community and what state /fed.
requirements are enacted which the community will have to comply with.
3. Changes to the current tree ordinance governing diseased trees and possibly
the nuisance ordinance governing the removal of dead /diseased /infested /risk
trees may be necessary. Ordinances should be reviewed and updated
according to what measures the municipality wants to enforce. Whether or not
city requires inspection and removal of infested ash will depend upon age of
the infestation and what state /fed. requirements are in place.
4. When replacing ash trees, property owners should choose a variety of species
from different plant genera and families (See "Recommended 'free List" in the
Appendix)
5. Residents should not move ash firewood from the area where the ash was
removed (Movement of bark - intact ash wood and debris will be regulated by
law once EAB has been found in Washington County and there is a
state /federal quarantine)

OPH EAB Management Plan -- 10/09 — 6
Removal and Processing of Infested Ash Trees
(Once LAB has been detected and there are infested trees in the city)
Once EAB is detected in the community, it will probably be required that infested
trees are processed on site, usually as production of wood chips. Otherwise, bark- intact
ash wood will need to be debarked or otherwise destroyed. Currently, May 1-August 31 is
considered the "active period" for TAB. It is currently recommended by the MN Dept.
of Agric. and MN DNR that no pruning or removal of ash trees take place during the
growing season. Infested trees would instead be left as "trap trees" during the growing
season for EAB egg-laying, then removed and destroyed between October I st and May
1 st to kill overwintering larvae and reduce the emergence of adults the following year.
Ash wood and debris could also be burned, but this would depend on regulations in each
municipality and whether or not burning restrictions are in force.
Options for wood utilization of infested, dead, dying ash trees are limited at the
current time. Production of small diamcter (< 1 inch) wood chips for use as landscape
mulch, and burning wood to generate energy, are two of the most likely options.
Cities should decide if they are going to provide/require the following items
related to removal of trees or• processing of EAB infested wood:
1. Arrange for Pick Up of infested wood on private property
2. Have a Drop Off site within the community for infested wood from private
pr'oper'ty
Note: Funding (State or Federal) for EAB Management:
Sonic state monies ]lave recently been appropriated to the Minn. Dept. of Agric. from the
Outdoor Heritage Fund. These are competitive matching grants for either Incident
Response (jurisdictions where EAB has already been confirmed) and Planning and
Preparedness grants for tree inventories and preparing for EAB management. "There is
not much information available yet regarding any Federal funding. If there are grant
opportunities in the future, these would most likely be competitive, cost -share grants, and
it probably would help a city's chances of being funded if they have an EAB
Management Plan in place. Municipalities and residents should be prepared for having to
take care of most of the cost of removing and replacing trees killed by EAB. Additional
funds for tree removal and planting should be added to future city budgets. Basing
budgetary requirements on current inventories of trees oil public property and rights-of-
way is critical to managing EAB impacts.

I lerms. et al.. 2009 North Centric] 1PJN/1 Center Bulletin)
Insecticides can effectively protect ash trees from EAB. Unnecessary insecticide
applications waste money. If EAB has not been detected within 10 -15 miles, your trees are at low
risk. Be aware of the status of EAB in your location. Current maps of known EAB populations can
be found at www.emeraldash borer. info, Remember, however, that once a county is
quarantined, maps for that county are no longer updated.
Trees that are already infested and showing signs of canopy decline when treatments are
initiated may continue to decline in the first year after treatment, and then begin to show
improvement in the second year due to time lag associated with vascular healing. Trees exhibiting
more than 50 percent canopy decline are unlikely to recover even if treated.
Emamectin benzoate is the only product tested to date that controls EAB for more than
one year with a single application. It also provided a higher level of control than other products
in side -by -side studies.
Soil drenches and injections are most effective when made at the base of the trunk.
Imidacloprid applications made in the spring or the fall have been shown to be equally effective.
Soil injections should be no more than 2 -4 inches deep, to avoid placing the insecticide beneath
feeder roots. To facilitate uptake, systemic trunk and soil insecticides should be applied when the
soil is moist but not saturated or excessively dry.
Research and experience suggest that effectiveness of insecticides has been less
consistent on larger trees. Research has not been conducted on trees larger than 25 -inch DBH.
When treating very large trees under high pest pressure, it may be necessary to consider
combining two treatment strategies.
XytectTM soil treatments are labeled for application at a higher maximum rate than other
imidacloprid formulations, and we recommend that trees larger than 15 -inch DBH be
treated using the highest labeled rate. Merito imidacloprid formulations are not labeled for use at
this higher rate. When treating larger trees with Merito soil treatments, best results
will be obtained with two applications per year.
Imidacloprid formulations for homeowners (Bayer AdvancedTm Tree & Shrub Insect
Control and other generic formulations) can be applied only once per year. Homeowners wishing
to protect trees larger than 15 -inch DBH should consider having their trees professionally treated.
Treatment programs must comply with any label restrictions on the amount of insecticide that can
be applied per acre in a given period.

Cost Estimates for Removal & Re- Planting
Approximate Cost of Re noval (tree and stump grinding) of Ash Tree - 12 in. dbli
(depends on factors e.g. tree condition, location, access, processing needs and 11 of trees in work request)
$600.
Approximate Cost of planting a 2.5 in. caliper deciduous tree; (B&B stock, planting and
I year guarantee)
$450.
The city currently has approximately 600 ash planted in boulevard right-of-ways (this is
approx. 41 % of the boulevard trees listed in a tree inventory completed in 2006) and
100 ash planted on city properly and in parks. Average trunk diameter of these trees is
estimated to be 12 in,
If the city follows the recommendation to remove 5% or more of the total ash population
each year, starting in 2010, estimated costs for ash removal per year would be: $21,000.
Replacement for these 35 trees would be: $15,750.
