RE: PLUS review PLUS 2005-06-15; La Grange
Dear Mr. Prusak
Thank you for meeting with State agency planners on August 3, 2005 to
discuss the proposed plans for the LaGrange project to be located on the
north side of Route 40, west of Old Route 896.
According to the information received, you are seeking approval for 232
residential units, 82,600 square foot of commercial, and a 135,000 sq. foot
elementary/middle school on 236 acres.
Please note that changes to the plan, other than those suggested in this
letter, could result in additional comments from the State. Additionally,
these comments reflect only issues that are the responsibility of the
agencies represented at the meeting. The developers will also need to
comply with any Federal, State and local regulations regarding this
property. We also note that as New Castle County is the governing authority
over this land, the developers will need to comply with any and all
regulations/restrictions set forth by the County.
Executive Summary
The following section includes some site specific highlights from the
agency comments found in this letter. This summary is provided for your
convenience and reference. The full text of this letter represents the
official state response to this project. Our office notes that the
applicants are responsible for reading and responding to this letter and
all comments contained within it in their entirety.

State Strategies/Project Location
* The developer has conducted an archaeological survey to determine more
specifically where the prehistoric archaeological sites are and if there
are concentrations of Revolutionary War material. This is highly
commendable. The DHCA needs a copy of the report when it is finished so that
they can better determine the actual site areas affected and preserved.
* The DHCA also needs to see where the 18th-century road trace and
19th-century feeder canal still exist and what can be preserved of those.
Any Revolutionary War site is likely to be highly ephemeral, since the
British troops were encamped for only a night or two in this area. Even
slight remains could be highly significant, however, because they have no
archaeologically tested military encampments in this state and they would
be associated with the only Revolutionary War battle to take place on
Delaware¹s soil. Prehistoric sites in the woods may be unplowed and have
very high integrity, which enhances the significance of such sites.
Street Design and Transportation
* DelDOT will require a TIS for this development.
* DelDOT encourages the developer to look for, and to the extent possible
provide for, access to the north.
* A side path for bicycle and pedestrian use should be provided along the
site frontage on Route 40.
* A bicycle and pedestrian path should be provided between the proposed
residential development and the proposed school.
* DelDOT anticipates requiring that some of the 5 entrances on Route 40 be
consolidated.
* It is recommended that the proposed cul-de-sac be eliminated in favor of
a loop tying into the proposed collector road at the first internal
intersection Natural and Cultural Resources
* It should also be noted that this parcel is bounded by headwater or near
headwater riparian wetlands associated with the Muddy Run Creek which
eventually drain to the water quality impaired Christina River subwatershed
of the Delaware Bay. In recognition of this concern, the DNREC strongly
recommends that the applicant preserve the existing riparian buffer (where
it still exists). Otherwise as

mentioned previously - a 100-foot buffer width is considered the minimum
acceptable distance from all wetlands and water bodies (including ditches).
* Because there is strong evidence that federally regulated wetlands exist
on site, a wetland delineation, in accordance with the methodology
established by the Corps of Engineers Wetlands Delineation Manual,
(Technical Report Y-87-1) should be conducted.
* Given the environmentally sensitive nature of this watershed, the
Department believes that the applicant should devote more effort to the
implementation of innovative efforts or BMPs to reduce impervious cover.
* The DNREC Water Supply Section has determined that the southeastern
corner of the proposed development falls within an area of excellent
groundwater recharge (see following map and attached map). The proposed
school area impacts the excellent recharge area.
* A review of the DNREC database has revealed that there may be suitable
habitat for the federally listed bog turtle (Glyptemys muhlenbergii) within
the proposed project area. Because the bog turtle is a federally listed
species, protected under the Endangered Species Act, its presence can
affect the scope of work. To ensure that the project will not impact bog
turtles or their habitat, Phase I surveys for bog turtle habitat should be
conducted.
The following are a complete list of comments received by State agencies:
Office of State Planning Coordination Contact: Herb Inden 739-3090
This project is located in Levels 1, 2 and 3 areas of the 2004 State
Strategies for Policies and Spending. For Levels 1 and 2 areas, State
policies support development activities that conform to the character of
the area and comply with State and local regulations. However, we
acknowledge the significant concerns raised by the State Historic
Preservation Office (SHPO), and ask that the developer work with SHPO in
this regard. A large portion of the back area is in a Level 3 area. The
cautionary note about Level 3, is, that these are areas where growth is
anticipated by local, county, and state plans in the longer term future, or
are areas that may have environmental or other constraints to development.
State investments may have other priorities in the near term future and
thus may not support development activities currently.
As for other issues, we encourage the use of our Better Models for
Development in Delaware book for design considerations. We also note that
the inclusion of a school site is welcome and understand that the idea of
linking this site with the Astro Middle school is being considered which we
highly encourage.

739- The Division of Historic and Cultural Affairs is not in favor of this
development, despite its location in the growth area for New Castle County.
The whole parcel of La Grange (N-576) is listed in the National Register of
Historic Places. The buildings, agricultural landscape, archaeological
sites, and road and canal traces are all important elements of our history.
The parcel is adjacent to the Aikens Tavern Historic District (N-3875). The
development will have adverse effects on the La Grange property through
destruction of some areas and through the change in setting and visual and
noise intrusions in other areas. Aiken¹s Tavern Historic District will also
be somewhat affected by visual and noise intrusions but to a lesser degree,
since the current development plans buffer the district by siting the
school on the far side of the La Grange buildings. The remainder of the
development is visually blocked from the district by the wooded area being
maintained around the new housing.
The developer has conducted an archaeological survey to determine more
specifically where the prehistoric archaeological sites are and if there are
concentrations of Revolutionary War material. This is highly commendable.
The DHCA needs a copy of the report when it is finished so that they can
better determine the actual site areas affected and preserved. They also
need to see where the 18th-century road trace and 19th century feeder canal
still exist and what can be preserved of those. Any Revolutionary War site
is likely to be highly ephemeral, since the British troops were encamped
for only a night or two in this area. Even slight remains could be highly
significant, however, because they have no archaeologically tested military
encampments in this state and they would be associated with the only
Revolutionary War battle to take place on Delaware¹s soil. Prehistoric
sites in the woods may be unplowed and have very high integrity, which
enhances the significance of such sites.
The entrance road into the housing development crosses a wetland. This may
require an Army Corps of Engineers permit. If it does, the developer will be
required to consult with this office about the project¹s effects on historic
properties under Section 106 of the National Historic Preservation Act of
1966 (as amended). There may be additional survey or documentation work
required, depending on the area of jurisdiction determined by the Corps.
The DHCA will be happy to help the developer understand and meet the
requirements of this process.
The buildings will be preserved as part of the school district¹s separate
parcel. They will need to develop a use and maintenance plan, and the DHCA
will be happy to give the school district technical advice on that. They
can call Joan Larrivee or Robin Bodo at 302-739-5685 for assistance.

1) The proposed development exceeds both DelDOT and New Castle County
traffic volume warrants for a traffic impact study (TIS). Accordingly,
DelDOT will require a TIS for this development. Because these studies
typically take 6 to 12 months from their initial scoping meeting to the
completion of DelDOT¹s review, they recommend that the developer have their
traffic engineer contact Mr. Todd Sammons of our Development Coordination
Section as soon as possible to obtain a scope for this study. Mr. Sammons
may be reached at (302) 760-2134.
2) DelDOT, in cooperation with New Castle County and WILMAPCO, has been
engaged for some years in an ongoing study of the Route 40 Corridor between
US Route 13 and Glasgow. Based on that study, we offer the following
comments:
a) A frequent problem in the Route 40 Corridor has been a lack of
connections between properties fronting on Route 40 and the adjacent
properties to the north and south. Route 40 is an arterial highway, which
means that its primary function is to serve through traffic. However,
without those connections, much of its capacity must be used for local trips
because the fronting properties have no other access. DelDOT recognizes that
Muddy Run and the developed lots in the Pencader Corporate Center are
obstacles, but they encourage the developer to look for, and to the extent
possible provide for, access to the north.
b) A side path for bicycle and pedestrian use should be provided along the
site frontage on Route 40.
c) A bicycle and pedestrian path should be provided between the proposed
residential development and the proposed school.
d) More information regarding the Route 40 Corridor Study, including a
typical section for the side path mentioned in item b above, is available
from the manager of that study, Mr. Mark Tudor. He may be reached at (302)
760-2275.
3) There are five access points proposed along Route 40. Preliminarily,
this number seems excessive. DelDOT anticipates requiring that some of these
entrances be consolidated.
4) Because the proposed school would adjoin the proposed Astro Middle
School, it is recommended that the feasibility of a pedestrian connection
between the two school sites be investigated.
PLUS 2005-06-15

August 23, 2005
5) It is recommended that the proposed cul-de-sac be eliminated in favor of
a loop tying into the proposed collector road at the first internal
intersection. DelDOT understands that cul-de-sacs are necessary in some
instances to make efficient use of the land where there are environmental
constraints. However, they are not conducive to good traffic flow or a
sense of community. Where possible they should be eliminated.
6) The response to Item 39 on the PLUS form indicates that the developer
would be willing to discuss a street connection to the Allan P. Brown, Jr.
property (Tax Parcel 11-025.00-010). DelDOT appreciates the developer¹s
willingness in this regard and recommend that the feasibility and utility
of such a connection be explored. The plan accompanying the PLUS form shows
a connection to lands of the Alfred Congo Estate (Tax Parcel
11-021.00-003). DelDOT supports that connection too.
7) The developer¹s site engineer should contact the Subdivision Manager for
New Castle County, Mr. John Schneider, regarding their requirements for
access. Mr. Schneider may be reached at (302) 760-2263.

Green Infrastructure
Portions or all of the lands associated with this proposal are within the
Livable Delaware Green Infrastructure area established under Governor
Minner's Executive Order #61 that represents a network of ecologically
important natural resource lands of special state conservation interest.
Green infrastructure is defined as Delaware¹s natural life support system
of parks and preserves, woodlands and wildlife areas, wetlands and
waterways, productive agricultural and forest land, greenways, cultural,
historic and recreational sites and other natural areas all with
conservation value. Preserving Delaware¹s Green Infrastructure network will
support and enhance biodiversity and functional ecosystems, protect native
plant and animal species, improve air and water quality, prevent flooding,
lessen the disruption to natural landscapes, provide opportunities for
profitable farming and forestry enterprises, limit invasive species, and
foster ecotourism.
Voluntary stewardship by private landowners is essential to green
infrastructure conservation in Delaware, since approximately 80 percent of
the State¹s land base is in private hands. It is in that spirit of
stewardship that the Department appeals to the landowner and development
team to protect sensitive resources through an appropriate site design.

August 23, 2005
Soils
Based on the New Castle County soil survey, wetland associated (hydric)
soils such as Fallsington and Mixed-alluvial were mapped on subject parcel.
Fallsington and Mixed alluvial soils are poorly-drained wetland associated
(hydric) soils that have severe limitations for development.
Wetlands
Statewide Wetland Mapping Project (SWMP) maps indicate the presence of
palustrine forested riparian wetlands along the Muddy Run Creek; isolated
palustrine forested and palustrine emergent wetlands were scattered
throughout the western portion of the parcel. These wetlands provide water
quality benefits, attenuate flooding and provide important habitat for
plants and wildlife. Vegetated buffers of no less than 100 feet should be
employed from the edge of the wetland complex. The developer should note
that both DNREC and Army Corps of Engineers discourage allowing lot lines to
contain wetlands to minimize potential cumulative impacts resulting from
unauthorized and/or illegal activities and disturbances that can be caused
by homeowners.
It should also be noted that this parcel is bounded by headwater or near
headwater riparian wetlands associated with the Muddy Run Creek which
eventually drain to the water quality impaired Christina River subwatershed
of the Delaware Bay. Headwater riparian wetlands are important for the
protection of water quality and the maintenance/integrity of the ecological
functions throughout the length of the stream, including the floodplain
system and/or water bodies further downstream. Since such streams are a
major avenue for nutrient-laden stormwater and sediment runoff, their
protection deserves the highest priority. In recognition of this concern,
the Department strongly recommends that the applicant preserve the existing
riparian buffer (where it still exists). Otherwise as mentioned previously
- a 100-foot buffer width is considered the minimum acceptable distance
from all wetlands and water bodies (including ditches). In cases where
natural buffer vegetation has been removed or reduced by past development
or farming activities, the developer is encouraged to restore/establish to
said buffer width or greater with native herbaceous and/or woody
vegetation.
Wetland Permitting Information
Impacts to palustrine wetlands are regulated by the Army Corps of Engineers
through Section 404 of the Clean Water Act. In addition, individual 404
permits and certain Nationwide Permits from the Army Corps of Engineers
also require 401 Water Quality Certification from the DNREC Wetland and
Subaqueous Land Section and Coastal Zone Federal Consistency Certification
from the DNREC Division of Soil and Water
PLUS 2005-06-15
Page 8 of 18
August 23, 2005
Conservation, Delaware Coastal Programs Section. Each of these
certifications represents a separate permitting process.
Because there is strong evidence that federally regulated wetlands exist on
site, a wetland delineation, in accordance with the methodology established
by the Corps of Engineers Wetlands Delineation Manual, (Technical Report
Y-87-1) should be conducted. Once complete, this delineation should be
verified Corps of Engineers through the Jurisdictional Determination
process.
To find out more about permitting requirements, the applicant is encouraged
to attend a Joint Permit Process Meeting. These meetings are held monthly
and are attended by federal and state resource agencies responsible for
wetland permitting. Contact Denise Rawding at (302) 739-4691 to schedule a
meeting.
Impervious Cover
Given the environmentally sensitive nature of this watershed, the
Department believes that the applicant should devote more effort to the
implementation of innovative efforts or BMPs to reduce impervious cover.
The Department believes that the amount of imperviousness generated by this
project (estimated average more than 50%) is excessive and should be
reduced. Reducing the amount of impervious surfaces by planting more trees
and/or the use of pervious paving surfaces (³pavers²) in lieu of asphalt or
concrete, are examples of ways to reduce such impacts. Research has
consistently shown that once a watershed exceeds a threshold of 10 percent
imperviousness, water and habitat quality irreversibly decline.
TMDLs
Total Maximum Daily Loads (TMDLs) for enterococci have been developed for
the Muddy River tributary a headwater tributary to the Christina River
watershed. A TMDL is the maximum level of pollution allowed for a given
pollutant below which a ³water quality limited water body² can assimilate
and still meet water quality standards to the extent necessary to support
use goals such as, swimming, fishing, drinking water and shell fish
harvesting. Based on the prescribed TMDL for bacteria in the vicinity of
this project, post-development discharge of enterococci must be reduced by
80 percent. Nutrient TMDLs have been prescribed for Delaware¹s portion of
the Christina River subwatershed capping nutrients, specifically
phosphorous at its current loading levels. Given the current land use on
the site, any development will lead to increased levels of nutrient
loading, thus, we highly recommend that all best management and site-design
practices be used which are geared towards reducing land disturbance near
waters or wetlands and reducing nutrient inputs to the ground and surfaces
waters.
PLUS 2005-06-15
Page 9 of 18
August 23, 2005
The applicant is encouraged to use BMPs such as buffers, pervious paving
materials, and greater upland forest cover preservation efforts to mitigate
the likely increases or impacts from bacteria and nutrient-laden surface
runoff following the development of this parcel.
Water Resource Protection Areas
The DNREC Water Supply Section has determined that the southeastern corner
of the proposed development falls within an area of excellent groundwater
recharge (see following map and attached map). The proposed school area
impacts the excellent recharge area.
According to the State law that created the Source Water Protection
Program, county and municipal governments with more than 2,000 residents
will be required to enact ordinances to protect Water Resource Protection
Areas. Municipalities with fewer than 2,000 residents are encouraged to
enact such ordinances. The following language has been excerpted from the
Source Water Protection Guidance Manual for Local Governments, Supplement 1
- Ground-Water Recharge Design Methodology. While the local ordinances may
not yet be in place, the developer may find the language useful in
modifying the site plan to protect water resources.
Water Resource Protection Areas (WRPAs) are defined as (1) surface water
areas such as floodplains, limestone aquifers, and reservoir watersheds, (2)
wellhead areas, or (3) excellent recharge areas. The purpose of an
impervious cover threshold is to minimize loss of recharge and protect the
quality and quantity of ground and surface water supplies in WRPAs.
New development in WRPAs may exceed the 20% impervious cover threshold, but
be no more than 50% impervious, provided the applicant submits an
environmental assessment report recommending a climatic water budget and
facilities to augment recharge. The environmental assessment must document
that post-development recharge will be no less than predevelopment recharge
when computed on an annual basis.
Commonly, the applicant offsets the loss of recharge due to impervious
cover by constructing recharge basins that convey relatively pure rooftop
runoff for infiltration to ground water.
The Department recommends the following (ranked in order of preference):
1) Preserve WRPAs as open space and parks by acquisition or conservation
easement.
2) Limit impervious cover of new development to 20% by right within WRPAs.
3) Allow impervious cover of new development to exceed 20% within WRPAs
(but no more than 50% impervious) provided the applicant develops recharge
facilities that directly infiltrate rooftop runoff.
PLUS 2005-06-15
Page 10 of 18
August 23, 2005
4) Allow impervious cover of new development to exceed 20% within WRPAs
(but no more than 50% impervious) provided the applicant develops recharge
facilities that infiltrate stormwater runoff from forested and/or grassed
surfaces with pretreatment.

A detailed sediment and stormwater plan will be required prior to any land
disturbing activity taking place on the site. The plan review and approval
as well as construction inspection for the commercial and residential
portions of the site will be coordinated through New Castle County Dept. of
Land Use. Contact New Castle County Dept. of Land Use at (302) 395-5470 for
details regarding submittal requirements and fees. The school site, if it
will be a public school on land owned by the State of Delaware, will be
reviewed by the DNREC Sediment and Stormwater Program. Contact Elaine Webb
with DNREC Sediment and Stormwater Program at (302) 739-9921.
A Notice of Intent (NOI) for Stormwater Discharges Associated with
Construction Activity must be submitted to DNREC Division of Soil and Water
Conservation along with the $195 NOI fee prior to plan approval.
Applying practices to mimic the pre development hydrology on the site,
promote recharge, maximize the use of existing natural features on the site,
and limit the reliance on structural stormwater components, such as
maintaining open spaces, should be considered in the overall design of the
project as a stormwater management technique.
Each stormwater management facility should have an adequate outlet for
release of stormwater. Any drainage conveyed onto this site from neighboring
properties must be adequately conveyed through the site to the discharge
point without interruption. The stream crossings downstream of the site at
Route 896BR and Route 896 should be investigated for adequacy in conveying
the flows from the developed site. The proposed locations for stormwater
facilities have not been provided on the plan; however, please be aware
that given some of the soil types found on the site, high water table may
be encountered as well as soils that are not conducive to infiltration.
Forests
According to the application there are 119.7 acres of forest on this
property and 25.4 acres is going to be removed. In reality, the amount of
forest that will be removed is probably higher once this site is built out
and homes, driveways, sidewalks, roadways, and stormwater management ponds
are constructed. Future landowner activities (construction of playgrounds,
sheds, swimming pools, etc.) also result in further clearing. Forest
fragmentation caused by the current site plan greatly diminishes the value
of this forest to a host of plant and animal species whether they are rare
or not. Larger, connected areas of forest are more beneficial to wildlife
than small, fragmented areas like those currently in the site plan. Forest
fragmentation separates wildlife populations, increases road mortality, and
increases ³edge effects² that leave many forest dwelling species vulnerable
to predation and allows the infiltration of invasive species. In addition,
when forested areas are cleared, displaced wildlife must disperse into
surrounding areas which often results in human/animal conflicts, including
interactions on the roadways.

Rare Species
A review of the DNREC database has revealed that there may be suitable
habitat for the federally listed bog turtle (Glyptemys muhlenbergii) within
the proposed project area. Because the bog turtle is a federally listed
species, protected under the Endangered Species Act, its presence can
affect the scope of work. To ensure that the project will not impact bog
turtles or their habitat, Phase I surveys for bog turtle habitat should be
conducted. If potential bog turtle habitat is found during Phase I surveys,
you are required to either:
1) Completely avoid all direct and indirect project impacts to the wetland,
in consultation with the U.S. Fish and Wildlife Service and Delaware
Division of Fish and Wildlife;
OR
2) Have surveys conducted to determine if bog turtles are present. In
accordance with Delaware¹s bog turtle site survey procedures, surveys must
be conducted by a State approved bog turtle surveyor between April 15 and
June 15.
Phase I surveys can be conducted any time of year when snow cover is not
present. If potential habitat is found, however, please note there is a time
of year restriction during which Phase II surveys for bog turtles must be
conducted. A Delaware approved bog turtle surveyor must be used to conduct
the surveys. Please contact Holly Niederriter (302-653-2880) to obtain a
list of contacts to conduct Phase I and, if necessary, Phase II surveys.
Recreation
It is recommended that sidewalks be built fronting at least one side of
residential streets and stub streets. A complete system of sidewalks will:
1) fulfill the recreation need for walking and biking facilities, 2)
provide opportunities for neighbors to interact in the community, and 3)
facilitate safe, convenient off-road access to neighboring communities,
parks, public mass transit stops, schools, stores, work, etc. It is also
recommended that a pedestrian crossing over Muddy Run be constructed to
connect the proposed community to the Astro Middle School location.
New Castle County is working to link community open spaces for greenway
conservation corridors. Consideration should be given to protecting the
community open space along Muddy Run with a conservation easement or
donation of land. For more information on easements, please contact the
Office of Nature Preserves at 739-9235. For information on Greenways please

No environmental impact is expected from the above inactive/active LUST
site(s). However, should any underground storage tank or petroleum
contaminated soil be discovered during construction, the Tank Management
Branch must be notified as soon as possible. It is not anticipated that any
construction specifications would be need to be changed due to petroleum
contamination. However, should any unanticipated contamination be
encountered and PVC pipe is being utilized, it will need to be changed to
ductile steel in the contaminated areas.
Solid Waste
Each Delaware household generates approximately 3,600 pounds of solid waste
per year. On average, each new house constructed generates an additional
10,000 pounds of construction waste. Due to Delaware's present rate of
growth and the impact that growth will have on the state's existing
landfill capacity, the applicant is requested to be aware of the impact
this project will have on the State¹s limited landfill resources and, to
the extent possible, take steps to minimize the amount of construction waste
associated with this development.
Air Quality
Once complete, vehicle emissions associated with this project are estimated
to be 17.8 tons (35,609.6 pounds) per year of VOC (volatile organic
compounds), 14.7 tons (29,482.3 pounds) per year of NOx (nitrogen oxides),
10.9 tons (21,752.6 pounds) per year of SO2 (sulfur dioxide), 1.0 ton
(1,936.4 pounds) per year of fine particulates and 1,489.3 tons
(2,978,695.9 pounds) per year of CO2 (carbon dioxide).
Emissions from area sources associated with this project are estimated to
be 7.2 tons (14,363.0 pounds) per year of VOC (volatile organic compounds),
0.8 ton (1,580.4 pounds) per year of NOx (nitrogen oxides), 0.7 ton

A significant method to mitigate this impact would be to require the
builder to construct Energy Star qualified homes. Every percentage of
increased energy efficiency translates into a percent reduction in
pollution. Quoting from their webpage, http://www.energystar.gov/:
³ENERGY STAR qualified homes are independently verified to be at least 30%
more energy efficient than homes built to the 1993 national Model Energy
Code or 15% more efficient than state energy code, whichever is more
rigorous. These savings are based on heating, cooling, and hot water energy
use and are typically achieved through a combination of:
building envelope upgrades,
high performance windows,
controlled air infiltration,
upgraded heating and air conditioning systems,
tight duct systems and
upgraded water-heating equipment.²
The DNREC Energy office is in the process of training builders in making
their structures more energy efficient. The Energy Star Program is excellent
way to save on energy costs and reduce air pollution. We highly recommend
this project development and other residential proposals increase the
energy efficiency of their homes.

The Delaware Department of Agriculture and the Delaware Forest Service have
no objections to the LaGrange application. The site is located on a
designated controlled

development area which is supportive of the Strategies for State Policies
and Spending encouraging responsible development in areas within a Growth
Level 3 Zone. The Delaware Department of Agriculture and the Delaware
Forest Service supports both an environmentally and culturally sensitive
design; one that will preserve the unique historical and environmental
features of this site.
Improved Landscape Design
The Delaware Department of Agriculture Forest Service encourages the
developer to use the ³Right Tree for the Right Place² for any design
considerations. This concept allows for the proper placement of trees to
increase property values in upwards of 25% of appraised value and will
reduce heating and cooling costs on average by 20 to 35 dollars per month.
In addition, a landscape design that encompasses this approach will avoid
future maintenance cost to the property owner and ensure a lasting forest
resource.
Native Landscapes
The Delaware Department of Agriculture and the Delaware Forest Service
encourages the developer to use native trees and shrubs to buffer the
property from the adjacent land use activities near this site. A properly
designed forested buffer can create wildlife habitat corridors and improve
air quality to the area by removing six to eight tons of carbon dioxide
annually and will clean our rivers and creeks of storm-water run-off
pollutants. To learn more about acceptable native trees and how to avoid
plants considered invasive to our local landscapes, please contact the
Delaware Department of Agriculture Plant Industry Section at (302)
698-4500.
New Castle County Unified Development Code Requirements
The Delaware Forest Service encourages the developer to coordinate its
activities with the New Castle County Office of Land Planning in the
development of this parcel. Presently, the Forest Service anticipates the
county identifying the following forestry requirements; forest mitigation
of trees lost during construction, the development of a landscape plan and
a maintenance plan for public open space areas. The Delaware Forest Service
may assist with the development of all of these aspects, please contact our
office with questions regarding these potential requirements.
