Re: Application of Ellen F. Emery
5925 Nassau Point Road
Cutchogue,New York 11935
Members of the Board of Town Trustees:
If the Board will recall, at the hearing held on September 21, 2011 concerning Ellen
Emery's application regarding the restoration of the bluff located on her property at 5925 Nassau
Point Road, Cutchogue,New York, I was requested to submit detailed plans concerning my
proposed work on the bluff.
When I inspected the bluff on the Emery property in the Spring of 2011, it was and still
is, in some portions, in terrible shape because it is overgrown with invasive species such as wild
grapes,honeysuckle and bittersweet. These species are choking out the native species on the
bluff. My plan is to remove these non-native, invasive species. Because the bluff is fairly steep
and the soil is primarily a sand and clay mixture, it makes walking on the bluff face difficult to
do the necessary work, so I needed the stairs and existing platform as a work station.
I am enclosing detailed drawings of plans to stabilize the bluff. In all of the drawings,
per the Board's request at the hearing, it is assumed that I have relocated the existing fence by
moving it landward six or seven feet so that it is basically in line with the original fence that
previously existed for many years on the property.
I am hopeful that the attached drawings will explain what I was trying to convey to the
Trustees at the hearing.
r -
It is my understanding that the Board requested me to do the following: (a)remove the
grass turf five to seven feet landward from the top of the bluff to the point where the fence would
be relocated; (b)reduce the size of the existing platform by approximately 50 percent to 32
square feet in its present location; and(c) remove the flooring on the platform and replace it with
untreated lumber.
There are several factors I need to bring to the attention of the Board concerning this
property. From the top of the bluff going landward or westward,the Emery property slopes
away from the top of the bluff. I bring this to the Board's attention because there is always a
concern that fertilizing along the top of the bluff will leach over the bluff and eventually find
these chemicals in the Bay. I have carefully examined the soil on this bluff as well as the
existing vegetation and can assure the Board there has been no leaching at the present time. This
is verified by merely examining the vegetation currently growing on the bluff.
The terracing system I intend to construct will have an additional benefit of trapping any
materials accidentally spilled on the top of the bluff. Further, at the bottom of the bluff,there is a
10-foot±,non-turf buffer on which there is a well-established stand of beach grass growing
primarily in sand.
DRAWING A is the first drawing I am submitting,which shows the present status of the
area on the top of the bluff from a landward point of view. Accompanying this drawing are
photographs labeled A-1 and A-2.
To remove the existing turf back five to seven feet to the relocated fence and create a
non-turf buffer would, in my professional opinion,be a colossal mistake. Every property
situation is somewhat different and unique. The present turf buffer with an established root
system that is preventing erosion has existed in the same location for many years. To show this,
I am attaching photographs (A-1)taken of this area on February 27, 1996. It is obvious from
looking at the photograph at the bottom of the page that the distance from the flagpole (which
has never changed location)to the top of the bluff at the point of inflection is virtually in the
same place as shown on the copy of the photograph(A-2)taken by the Board of Trustees some
16 years later at their inspection on September 14, 2011.
The owner, Ellen Emery, informs me that her father planted Zoysia Grass plugs all along
the top of the bluff in the 1970's solely for the purpose of preventing erosion. What is interesting
in reviewing these photographs and physically inspecting the property is the proof that this
Zoysia has prevented erosion and that the grass turf is growing seaward over the edge of the
bluff from the point of inflection downward.
The existing turf in this area consists primarily of Emerald Zoysia,with some Fescue and
Rye,which in the rear yard of this property has worked extremely well. These grasses,
especially the Zoysia due to its creeping stolens and short rhizomes,have developed over the
years into a thick mat which in effect has prevented any erosion on the top of the bluff. In fact,
the root structure in some of the areas that I tested is as much as 10 to 12 inches in depth. It is
further noted that the Zoysia Grass is used in many areas as a ground cover to prevent erosion.
Therefore, it is my recommendation not to remove this turf grass buffer on the Emery property
2
r
because it has proved to be very effective to prevent erosion and will continue to do so if not
significantly disturbed.
To create a non-turf buffer in this area would expose the land to the elements, and no
matter what you tried to grow in this area, you could not prevent erosion at the top of the bluff.
In my opinion, the top of the bluff would erode in time whereas it has remained stationary for a
very long time with the present turf buffer.
As I previously stated, every property is different when you consider the variables, such
as: Types of soil, sun, and wind conditions. This grass turf buffer on the top of the bluff on the
Emery property is very healthy and should remain.
The southeasterly portion of the bluff on the Emery property is an entirely different
situation. Up to +15 feet northerly of the southerly property line,the top of the bluff is seriously
eroded because it had caved in and was undermined due to the storms in the early 1990's. The
result was that the southeast corner of the Emery property was undermined and the easterly
portion of the bluff in this area caved, leaving a sheer four-foot drop. The point I am making is
that this failure is not the result of the grass turf on the top of the bluff as the erosion did not
occur from the top, but it is a result of the undermining of the adjacent property as well as the
southeast corner of the Emery property. You have two different situations to control erosion on
the Emery property.
What I propose to do is to enhance and stabilize the top of the bluff as shown on
DRAWINGS B and C. These drawings (not to scale) are illustrations of the work I intend to
accomplish. Where there is Zoysia grass turf seaward at the point of inflection and no erosion, I
intend to slice this turf into sufficiently wide strips,roll it back approximately 24 inches, and
while the turf is rolled back,to tuck under it a permanent turf reinforcement mat, i.e. V. Max
C350. (I am enclosing as Attachment 1 some literature for your review.) After tucking this
reinforcement mat underneath the cut sod, I will overlay the sod on top of the reinforcement mat
and continue the reinforcement mat down approximately another two or three feet, depending on
the conditions. In this extended area of the mat, I intend to verify there are no voids underneath
the mat. If there are any voids, I will pack in good soil underneath, and plant beach grass plugs
throughout this exposed area of the mat. When this is completed, I would anchor down the mat
to enable the root structure of the grasses to stabilize. In that way,there would be no slippage of
the mat and plant growth would be promoted. The details of my proposed work are shown on
DRAWINGS B and C.
As I explained,the southeasterly bluff area has seriously eroded. I intend to do this work
first after obtaining the necessary permit. The details of what I am proposing to do are shown on
DRAWINGS C and D. This involves building a retaining wall which will be anchored into the
existing bluff area. All of the work will be done by hand so there will be a minimum amount of
damage to the bluff area.
Lastly, I intend to install a four-inch kick plate at the bottom of the fence when it is being
relocated so it will act as a stop to any possible runoff going over the bluff. As I have stated
3
1
previously, in good conscience I cannot remove this very healthy and hearty turf buffer as it
presently exists because it has, in fact,prevented any erosion over the top of the bluff.
DRAWING E is what the bluff will look like when it is completed with the terracing
system and the plants that I propose.
At the hearing,the Board required that I reduce the size of the existing platform to 32
square feet and remove the present platform flooring as the Board did not like the treated lumber
that I used.
It should be noted that this platform was approved by the New York State Department of
Environmental Conservation in 1973,when it granted a permit to Costello Construction
Company to construct an 8-foot by 12-foot platform; apparently only an 8-foot by 8-foot
platform was actually constructed. When I inspected this platform in April of 2011, it was sturdy
and functional. The work that I did was mainly cosmetic repair as the platform was in good
condition, and I did not want to disturb the bluff, so the repairs were only made where required.
Since some of the flooring showed wear, and since I was doing the installation of the stairs,the
owner decided to replace the floor for appearance purposes. When I removed the existing
flooring and inspected the understructure, I found the floor joists were solid and did not need any
repair or work. The three posts landward were basically at ground level on the bluff and were in
good condition. I left them in place as they in fact were helping prevent erosion. With the fascia
board on the landward portion, it acted as a terrace. The three seaward posts were satisfactory,
but since I was doing the work on the stairs, it was little or no effort to replace the southerly post
in the same spot next to the stairs. Although serviceable,the northerly post had shrunk a little. I
could have easily put a shim plate at the top, but since I was working in the area I decided to
replace it,which I did by hand with a post hole digger, installing a new post in that location. The
middle post I did not touch, not only because it was solid but it made firm contact with the deck
and I did not want to disturb the bluff any more than I had to. The way the platform was
previously constructed, I had to remove the railing to replace the floor, so I added a fascia board
to attach the new railing to it. It also should be pointed out to the Board that it makes absolutely
no sense to destroy this perfectly serviceable existing deck. In addition,while the work is done,
it runs the risk of doing damage and causing further bluff erosion in this area. For that reason
alone,there will be no work done on this platform until the Spring, when I will be able to shore
up any damage and install the terracing system to prevent any erosion.
The wood I used on the flooring was a treated wood known as Weather Shield ProWood
Micro Pressure Treated Lumber which I purchased at Home Depot. (Attachment 2 is some
literature for the Board to review.) I chose this particular lumber because, after doing quite a bit
of research and considering the expense involved when I replaced the stairs, I wanted to use a
product that was safe,would last and would protect against termites, carpenter ants,bees and
decay. This product is certified as an environmentally preferred product. It has been proven to
have no eco-toxins or other environmental impacts.
I remember at the hearing that some of the Board members said this material was not
allowed by Code. I was troubled by this comment as the manufacturer had assured me the
product was environmentally safe. After reading the Code, I can find no prohibition for this type
4
of material on the bluff on the Emery's property. I believe the Board was referencing those
sections in the Code where it states that pretreated lumber, especially CCA and ACQ, are
prohibited, but when I read the Code I saw that it applies only to pretreated lumber to be used in
water-operation areas such as bulkheads,retaining walls, revetments, gabions, docks and jetties.
What I am trying to say is that the platform on the Emery property is not in any of these areas
and I don't believe under the Code is prohibitive. Also,the material is an environmentally safe
product.
I am hopeful that the Board, in reviewing the details of what I propose as shown on the
drawings,will approve same. I have extensive experience in restoring bluffs along Long Island
Sound and Gardiner's Bay, as well as along creeks in the Town of Southold. From my
experience, I can assure the Board that my proposal will stand the test of time. If approved by
the Trustees,the work will be done in the Spring of 2012 because it is too late now to plant any
type of vegetation or to disturb the bluff and have any chance of regrowth. Further,the existing
dormant vegetation and vines and brambles that exist should be able to hold everything in place
until the Spring.

Saves Trees
Using pressure-treated wood extends the wood resource.In North America,using pressure-treated wood saves millions of trees each year.
Less Energy Consumption
Comparing total energy costs of other building materials—the costs to acquire the raw material,transport it,process it into a useful product
and then actually use it—wood outshines its competitors. For example,steel wall studs require almost nine times more energy to produce than
wood studs.
Forest Growth
The U.S.has far more trees today than it did in the 1920s—even though the population has increased by 143%.Since 1940,we have been
growing more wood than we've been harvesting in America(today,growth exceeds harvest by 37%).
Earth-Friendly
Wood is renewable,sustainable,recyclable and durable.Steel,concrete and plastic,on the other hand,are made from non-renewable
resources.
Life-cycle Analysis Shows Advantages
Environmentalists use life-cycle analysis to measure the environmental impact of a product.The life-cycle analysis of pressure-treated wood
shows that it's environmentally superior because it uses renewable resources and recycled material,requires little energy to produce and
distribute,and produces little waste.
No Environmental Impacts from Copper
The copper in wood products treated with the MicroPro preservative system bonds readily to organic matter in the soil.Result:the copper
becomes biologically inactive,thus causing no eco-toxic or other environmental impacts.
Reduced Air Emissions
The solution containing the preservative formula is four times more concentrated than the industry standard.As a result,fewer trucks are
required for transport.Fewer trucks,combined with the absence of monoethanolamine(MEA)in the production process,result in a reduction
of air pollutants from tailpipe emissions and associated impacts,including:soot,nitrous oxide,volatile organic compounds(VOC's),
particulate matter,and reduced impacts of acid rain,smog,and oceanic acidification.
Reduced Greenhouse Gas Emissions
The absence of MEA in the production process,combined with the reduced use of fuel and fewer trucks,means that using the MicroPro
preservative in lieu of standard wood treatment formulations reduces an estimated 20,000 tons or more of greenhouse gas emissions each
year(this is equivalent to the annual emissions of approximately 2,200 SUV's).
Recyclable
Once taken out of service,treated lumber can be reused as landscaping,garden edging,steps or many other popular outdoor projects.

ProWood Micro CA treated wood utilizes a proven technique where copper is milled into sub-micron sized particles.These copper particles
are then suspended,instead of dissolved,in the wood preservative solution used during the pressure treatment process.
Using micronized copper eliminates the need for a solvent,which is required for ACQ and Copper Azole.This results in key benefits to the
consumer:better performance,better corrosion properties and a fresh,more natural appearance.
How do I know if my treated wood is properly treated for my intended end use?
First,you will want to look for a lumber end tag. Each piece of Universal Forest Products'treated wood contains a tag with information
regarding the preservative used,the appropriate end use(i.e.above ground or ground contact),the quality standard and safe handling
information.
In some cases,building code regulations mandate the use of treated wood that meets certain standards.The International Code Council
(ICC)develops model building codes for use nationwide.ProWood'Micro CA has been evaluated by the ICC-ES to be code compliant with
the details listed under the ESR-1980 Re ort and the ESR-2240 Report.In the case of treated wood the ICC relies primarily on the American
Wood-Preservers'Assoc.(AWPA)to determine appropriate standards of treatment for specific preservatives in specific end uses.They also
offer their own ICC Evaluation Service as a way to determine if a product is suitable.Quality control measures are laid out to ensure the
treated wood that is produced meets the quality standards In addition to in-house quality checking,manufacturers are also required to
subscribe to an independent inspection agency who verifies for customers that the wood was treated in accordance with the applicable
standards.Manufacturers who are in good standing with the 3rd party inspection agency will carry that agency's quality mark on the lumber
end tag.
For an independent viewpoint on how to tell if your wood is properly treated,view the USDA's Forest Products Laboratory TechLine on new
wood treatments.
What ingredients make up ProWood Micro CA?
ProWood Micro CA is a waterborne system that is copper based.Together,the compounds of copper and azole(for CA)provide protection
from a broad spectrum of fungi and termites,preventing rot and decay.Laboratory and field studies have proven that micronized copper
products provide protection against fungal decay and termites in both above ground and ground contact applications.
How does ProWood Micro CA differ from ACQ?
ProWood Micro CA uses"micronized"copper particles that bond permanently to wood cells.ProWood Micro CA causes less corrosion in
fasteners and gives wood a lighter,fresher appearance after treatment than ACQ.
Is special handling required?
Our Safe Handling Information Sheets outline specific handling tips.
The single most important precaution is DO NOT BURN TREATED WOOD When pressure-treated wood is burned,the preservative
chemicals concentrate in the ash and can be inhaled.Wear gloves when handling treated lumber.And always wear safety goggles and a
dust mask when sawing or cutting treated lumber just as you would with untreated lumber
How safe is treated wood?
ProWood Micro CA pressure treated wood is very safe when used in the appropriate applications as directed.The preservative infected into
lumber reacts with the wood substance to form an insoluble complex.It won't evaporate or vaporize.ProWood Micro CA treated wood is
clean,odorless,non-staining,safe to work with and handle Its built-in protection is non-irritating to for dermal contact with children,adults,
animals and plants.The minute amounts of preservative released during a treated wood structure's serviceable lifetime have been carefully
studied The conclusion is clear.it is safe for the environment and safe for contact with people andpets.In our opinion,ProWood Micro CA
treated wood—as with any wood product—should not be used where household pets would be likely to chew on or ingest the wood.The
process used to treat ProWood Micro CA is the first to gain Environmentally Preferable Product(EPP)as certified by Scientific Certification
Systems(SCS).Scientific Certification Systems is a third-party certification services and standards development company.According to the
EPA,to be EPP certified means that the product has a reduced impact on human health and the environment when compared to other
products that serve the same purpose.

Osmose,Inc.MicroPro earned Green Approve Product certification from the National Association of Home Builders(NAHB) Research
Center under the National Green Building Standard Program.By using ProWood Micro products,architects,specifiers,homebuilders and
contractors are eligible to receive points toward a budding being certified under the National Green Building Standard.
What is GREENGUARD Children&Schools Certification?
The GREENGUARD Children&Schools Certification is awarded to products that are intended for use in schools,daycares,or other
locations where children spend large amounts of time.The certification shows that a product adheres to the highest standards for chemical
emissions,ensuring public safety,regardless of age.
Do you recommend painting ProWood Micro CA treated wood?
Although ProWood Micro CA provides a surface that is easier for paints to cover,we do not recommend painting it ProWood does not need
protection from the elements,paints and varnishes peel over time and maintenance of a horizontal painted surface is frequent and tedious.
But,if your decorative decisions do call for paint,make sure the wood is dry before application.(Pour some water over the surface If it
beads,wait,if it seeps into the wood,it's ready to paint.)
Can preserved wood be used indoors?
Treated wood may be used indoors for any application except cutting boards and countertops.

b"
Why can I use pressure-treated wood for a picnic table and not a countertop?
Simply because picnic tables are primarily used for serving prepared food while a kitchen countertop is used primarily as a cutting surface for
raw food.
Can treated wood be used in gardening?
Yes Treated timbers used to construct raised vegetable and flowerbeds are increasingly popular and practical.Recent scientific tests prove
there is no significant uptake of preservatives into plants.And treated wood used for tomato stakes,flowerbed edging,planters,retaining
walls,trellises,and compost bins have the added advantage of lifetime durability
Check out our bloc post on this topic.
What is the significance of the tags stapled to my lumber?
Universal Forest Products places end tags on all of its pressure-treated products to ensure that our customers know key information about
the product such as the type of warranty,whether it is for use in direct ground contact or only above ground applications,and where
applicable,information needed for acceptance by local budding codes.Many of these tags on our treated wood products even have detailed
information on the safe handling of our pressure-treated products,the same information contained in the Safe Handling Information Sheets.
Are there different types of treated wood for different uses?
Yes.Our tags will always state"above ground only"or"ground contact"so you can be sure you are using the right material for the job.Higher
levels of preservative are available for special purposes such as extensive moisture/earthen contact-e g.,in foundations,pole barns,fresh&
saltwater docks,culverts,etc.For more detail, refer to the End Uses for ProWood page.
Any fastener recommendations when building with ProWood Micro CA?
Use hot-dip galvanized fasteners or other fasteners as required by building codes;otherwise,your treated wood will last longer than the
unprotected fasteners you've used to put it together.In addition,carbon steel fasteners may be used for UC1 and UC2 interior or above
ground,weather protected applications such as sill plates,interior framing and interior trusses.Since ProWood Micro CA is less corrosive
than ACQ,these recommendations are the same as they were with CCA-treated lumber.Fastener manufacturers may also recommend
products that work well with ProWood Micro CA.View the ProWood Micro Advantage-Fasteners page for more information.
Aluminum building products can be placed in direct contact with ProWood Micro CA treated wood products used for interior uses and above
ground exterior applications such as decks,fencing,and landscaping projects Examples of aluminum products include siding,roofing,
gutters,door and window trim,flashing,nails,fasteners and other hardware connectors.Aluminum contact is not recommended when
ProWood Micro CA treated wood products are immersed in water or are subject to frequent and prolonged wetting or other severe exposure
conditions.In such cases,a moisture resistant protective barrier should be placed between the aluminum products and ProWood Micro CA
treated wood.
I cut the end off of my pressure-treated wood,and it looks like it isn't treated in the middle.Do I have a bad piece of treated wood?
No.Most commonly this is heartwood which is naturally decay resistant.This is doesn't indicate if the wood was properly treated,and you do
not need to be concerned.With the exception of some Western species,these end cuts do not require any special treatment. Refer to the
ProWood Micro Warranty and ProWood Micro CA Warranty for details
Brush-on Preservatives for Field Cuts
According to American Wood-Preservers'Standard M4-06,lumber and timber which are used in above ground applications and are of
sapwood species such as southern,red or ponderosa pine,generally do not require treatment to provide a good service life.This category
includes the majority of the treated products Universal Forest Products provides.Other heartwood species,typically found in the Western
U.S.should be field treated when out or drilled. If you are concerned about wood exposed due to cutting or drilling,you can use a brush-
applied preservative
Home centers and lumberyards often carry brush-applied preservative systems based on two different active chemicals:either copper
naphthenate or IPBC(3-iodo 2-propynyl butyl carbamate).These systems should be applied,in accordance with their labels,to any surface
exposed by damage or field fabrication.Users should carefully read and follow the instructions and precautions listed on the preservative
system label when using them.
Is it safe to use pressure treated lumber for animal enclosures such as a bird feeder or fish pond retaining wall?I have heard that
leaching may be a problem.
Outdoor enclosures for animals are an appropriate use for ProWood Micro CA pressure treated lumber when you keep in mind a few factors.
For ponds make sure to choose lumber that is treated to the proper retention of preservative in the wood.The lumber end tag should note the
end use as"Ground Contact/Freshwater Use."A small amount of leaching takes place,and copper that is used in many pressure treated
lumber does have aquatic toxicity.Generally the levels of leaching will only be problematic in situations where there is a large amount of
treated wood compared to the volume of water and where there is a low water flow For more information,the USDA Forest Product Lab
discusses treated wood and environmental impact.
After my project is built,is any special maintenance necessary?
Left unfinished,treated wood ages gracefully,eventually softening to an attractive driftwood gray.On flat surfaces such as decks,however,
leaves and other debris may collect and create unsightly stains.Even if your lumber has the locked-in protection of factory-applied water
repellent,you'll want to follow an annual maintenance program that includes a semitransparent stain or a sealant which contains an ultraviolet
stabilizer.If you stain your project,a quality penetrating latex or oil base stain is recommended.
Does ProWood Micro CA qualify for continuing education learning credits?
