Part 1: Introduction
History of Application:
In January 2004, a local development firm purchased 6.69 Acres (the Haden Place
Property). An R-2 single-family detached development plan was submitted to Albemarle
County for review. In January 2005, Wendell Gibson, Inc. (the applicant) purchased the
property from the local developer. Mr. Gibson is a local residential builder who lives in
Western Albemarle County and has been building in the Crozet Growth area for several
years. After a pre-application conference and several additional meetings with
Community Development Staff, Mr. Gibson was advised that a pre-application submittal
to the Planning Commission would not be required and that County Staff could support a
rezoning application to Neighborhood Model District. ZMA 2005-0007 was submitted
on May 31, 2005 proposing a 40-unit Neighborhood Model District for the property.
During the application review, several questions arose regarding: the requirement of
off site road improvements, the requirement for onsite private road frontage, the Crozet
Master Plan guidelines for affordable housing and density provisions, and the treatment
of the existing 1882 house. A Planning commission work session was held on September
13,2005 and addressed these topics. Additionally, the Planning Commission
recommended that the proposed layout should address the integration with Ballard Fields
development, being built on the adjoining property to the south. The ZMA application
was resubmitted on January 18, 2006 following the recommendations from the
September 13 work session. In February of 2006, Mr. Gibson was notified that the
Crozet Master Plan interpretation of allowable densities had been revised to reflect net
acreage (interpreted as 80% of gross) and the current application (dated October 2,2006)
is based on a net acreage of 5.35 acres.
Page 1 of 22
Regional Justification:
In the Application Plan, sheet A-4 shows the relationship of the property to regional
facilities and services in the area. As Haden Place is located near the center of the Crozet
Growth Area, the following distances to and from regional facilities, services, and
districts are of note:
1. Crozet Elementary School:
2. Brownsville Elementary School:
3. Future Elementary School site:
4. Henley Middle School:
5. Western Albemarle High School:
6. Crozet Volunteer Fire Department:
7. Western Albemarle Rescue Squad:
8. Jefferson Madison Regional Library:
9. U.S. Post Office
10. Downtown Crozet Business District:
11. Western Park (Old Trail):
12. Claudius Crozet Park:
13. Future Eastern Park:
14. Rt. 240 Industrial/Commercial Center:
15. Old Trail Commercial Center:
16. Route 250 Commercial Center:

1.6 miles
While all of the above services, facilities, and districts serve the entire regional
population of Western Albemarle County, the quality and quantity of the services and
necessary infrastructure is directly dependant on the travel distances required. For
example, residents at Haden Place could walk to school, work, the post office, a park,
shops, or a restaurant.
Existing Site Conditions:
The existing site is 6.69-acres. There is 460 feet of existing road frontage on Haden Lane
and 575 feet of existing road frontage on Killdeer Lane. There is 30 feet of fall from the
high point (northwest corner) of the property to the low point (southeast corner) of the
property. A poorly defined ridge runs from Northwest to Southeast and divides the site
into two drainage areas of approximately 6.1 acres and 0.6 acres. The typical slope of the
land is about 4%. There are 5 areas, totaling 4,970 square feet (more or less), on the site
with slopes greater than 25%. Three quarters of these "steep slopes" are within an
existing wooded area at the southwest corner of the site. Approximately 18 % of the site,
lying in the southwest corner along Killdeer Lane, is wooded and contains the steepest
topography. The existing trees in this area are mixed hardwoods with trunk diameters of
6-18" on average. The remainder of the site is open with a groundcover of fescue. There
is an existing vacated homesite on the east side of the property. The homesite includes a
Page 2 of 22
residence, 4 outbuildings, a well and cistern, driveway, walkway, and approximately 6-8
hardwood trees, and 3-4 dogwood and ornamental trees.
The Proposed development plan incorporates the existing topography and site conditions
in the following manner:
1. The grade change from Killdeer Lane to Haden Lane is incorporated into the
building sections through the site. Village Homes proposed on Killdeer Lane
will have drive under garages. And structures on the East side of Haden Place
will have basement garages as well. This allows front porches and entrances
on Killdeer Lane, Haden Place, and Haden Lane to be oriented on a pedestrian
scale to the street.
2. The existing swale at the southwest comer is proposed to be incorporated into
an onsite stonnwater management facility for the site. Proposed grading will
allow over 95% of the proposed residential roof drainage and all of the
interior vehicular travel way and parking drainage to flow to this facility.
Frontage improvements including stonn drainage is proposed along Haden
Lane that would allow all additional runoff to flow to Powell's Creek.
3. The existing wooded area and steep slopes in the southwest comer are
incorporated into a 0.29-acre tree preservation area of dense hardwoods. This
tree preservation area is over 50 feet deep. While the application plan does not
preserve the 6-8 mature hardwoods near the existing house, the plan proposes
the planting of 9 street trees on Haden Lane, 13 on Killdeer Lane, 16 on
Haden Place, and 23 on the connector road, for a total of over 60 street trees.
Along with the ornamental plantings in the open space and on the lots, the
proposed tree canopy will greatly exceed the existing canopy.
Neighborhood Model Principles, pursuant to Section 20A.3:
Pedestrian Orientation: The Application Plan provides 2,700 linear feet of
sidewalks, lined with street trees and no driveway crossings. The pocket park
provides a walking destination and link to the Ballard Fields and Old Trail
neighborhoods. The private road easement at Haden Place is designed as an
urban streetscape and community green rather than a parking lot and cul-de-sac.
Neighborhood Friendly Streets and Paths: All travelway widths meet
minimum requirements to discourage speeding traffic. Chicanes are designed to
delineate on street parking while maintaining narrow widths. Street trees are
provided in the landscape strip where practical. Alleys provide rear loaded
utilities, parking, trash service, and private space; all of which encourage public
space along the streetscape in front.
Interconnected Streets and Transportation Networks: The Application Plan is
unique in that it will allow vehicular and pedestrian egress from the site in 4
different directions (five if the Jarman Hill connection is approved). The pocket
park also provides and additional pedestrian connection to Summerford Lane and
Page 3 of 22
a future dedication could provide additional connectivity and realignments
through the pocket park.
Parks and Open Space as Amenities: Conceptual calculations show that the
area required for a water quality bio-filter is 5,300 square feet. The graded area in
the pocket park is approximately 26,000 square feet and the tree conservation area
is approximately 13,000 square feet. This provides unique opportunity to provide
stonnwater management that is blended in a landscaped passive park setting
adjacent to a substantial stand of existing hardwoods. A footpath, benches, and a
picnic pavilion will be provided to further enhance this open space as an amenity.
The "green" at Haden Place creates a vehicular turnaround that functions
differently from the traditional cul-de-sac. The paved area measures 90 feet by 92
feet with an 18 foot deep parking bay on one end. A 2,800 square foot landscaped
green is located in the center of the paved area. The result is a narrow, one-way
travel isle with lawn area that is shared by the community.
The 10,600 square foot open space "buffer" along the northern perimeter of the
site provides screening from existing adjoining residences, greater building
setbacks for the 4-unit townhomes, and community area for playground
equipment, gardens, and I or lawn space.
Neighborhood Centers: The 1.04 acre pocket park provides a neighborhood
center (on a residential and pedestrian scale) for Haden Place, Ballard Fields, and
the existing residences on Haden Lane and Killdeer Lane. The Green on Haden
Place provides a similar neighborhood center for the residents on Haden Place.
Buildings and spaces of human scale: Twenty of the proposed 34 residences are
single-family detached homes with front widths of32 feet or less. The remaining
14 proposed units are designed as 3 blocks oftownhomes separated by a
pedestrian oriented streetscape. The largest building footprints on the Application
Plan are 2 five-residence townhouse building of approximately 4,500 Square feet.
These buildings, along with the green space on Haden Lane and the pocket park
across the connector road create a neighborhood design that focuses on the
neighbors rather than the through traffic and vehicular access.
Relegated Parking: All off street parking for Haden Place is relegated to the rear
alleys. Some on street parallel parking is provided for guests on all streets. In
addition rear-loaded surface parking is located to provide minimal visual impact
from nearby public and private streets.
Mixture of Uses and Use Types: Earlier versions of the Application Plan
provided for a greater flexibility of commercial uses allowed on the first floor of
the proposed townhomes. As the zoning regulations in Albemarle County are not
consistent with allowing these uses as they were previously proposed, the current
Application Plan allows for home occupations and daycare facilities (wi 1-5
Page 4 of 22
children) as By-Right uses. While the Crozet Master Plan suggests comer stores
as a By-Right use in this location, the Application Plan does not allow for this
(other than that which would be allowed under the home occupation regulations).
Mixture of Housing Types and Affordability: The Crozet Master Plan suggests
Cottages, Houses, LivelW ork units, Accessory units, and Inns as proposed types
of housing in the CT3 areas. The Application Plan provides Cottages, Houses,
and Townhomes (which could function as LivelWork units using home
occupation guidelines). As discussed at a worksession with the Albemarle
County Planning Commission in September of2005, detached cottages are
proposed in lieu of Accessory units to provide a unique opportunity for
affordability in a detached "for sale" residence.
The applicant has met with County Staff on several occasions to discuss the
design of affordable housing in Haden Place. The village homes on Haden Lane
and Killdeer Lane will likely be the most expensive product in Haden Place and
the Cottages will be the least expensive. Six for-sale affordable dwelling units
shall be made available within Haden Place as provided in Proffer 4.
Redevelopment: This existing R-2 property is uniquely located near the center of
the Crozet Growth Area in an existing neighborhood with frontage on two
existing streets. The site is located within ~ mile of approximately 6 other
development plans that are currently being built or reviewed. The Application
Plan provides a piece of the connectivity that would assist pedestrian, bicycle, and
vehicular flow between Haden Lane, Killdeer Lane, Ballard Fields, Jarman Hill,
and downtown Crozet.
Site planning that respects terrain: The lowest point on the site is proposed to
serve as an on site stormwater management facility with outfall into an adjacent
off site stonnwater drainage system. Blocks B, D, E, G and are proposed as
residential blocks having buildings with basement garages. This allows the fronts
of all buildings to have finish floor elevations above street level. Existing critical
slopes and wooded areas in the southwest comer of the property are proposed to
be disturbed to allow needed road improvements to Killdeer Lane. 500 square
feet of critical slopes in the northeast comer of the site are proposed to be
disturbed to allow needed road improvements to Haden Lane. 400 square feet of
critical slopes in the northeast comer are proposed to be disturbed to allow one
house site on Haden Lane. 3,000 square feet of critical slopes are proposed to be
undisturbed.
Clear Boundaries with the rural areas: All adjoining properties are zoned R-6
and R-2. The nearest boundary with the rural areas, as described in the Albemarle
County Comprehensive Plan, is approximately 0.75 miles.
Page 5 of22
Infrastructure:
Transportation:
The proposed plan would provide an East I West connection between
Haden Lane and Killdeer Lane. Haden Lane and Killdeer Lane
provide connections between Jarman's Gap Road and Old Trail Drive,
and Old Trail Drive and Jarman's Gap Road provide connections
between Crozet Avenue and U.S. 250. Mr. Gibson proposes to
provide full frontage improvements along his property frontage on
both Killdeer Land and Haden Lane and any improvements on
Killdeer Lane and Haden Lane as required by the Department of
Transportation to accommodate additional traffic generated by the
Haden Place rezoning application. Mr. Gibson has further agreed that
no vehicular connections shall be made between Haden Lane and
Killdeer Lane until such time that sight distance improvements are
made at the intersection of Jarman's Gap Road and Killdeer Lane.
Design Traffic Volumes for Haden Place are as follows:
14 SFD Village Homes @ 10 tripsl day
6 SFD Cottage Homes @ 8 tripsl day
14 SF A Townhomes @ 6 trips I day
Total ADT
= 140 trips
= 48 trips
= 84 trips
= 272 trips
The design traffic volume for the existing 16 lots on Haden Lane is
160 trips per day and the design traffic volume for the existing 8 lots
on Killdeer lane is 80 trips per day.
Stonnwater Management:
The property lies within the Lickinghole Creek Regional Facility's
drainage basin, which manages peak flow from the IO-year frequency
stonn. In addition to providing a prorated fee to this facility, a conceptual
onsite facility has been incorporated in the application plan. The proposed
onsite facility outfalls into an existing stormwater pipe system, and some
additional onsite detention is anticipated in order to comply with the
Albemarle County Water Protection Ordinance.
Two off site easements have been recorded to provide additional drainage
east to Powell's Creek. Approximately ~ acre of the site will drain
Page 6 of 22
through this easement. A small water quality facility is proposed in
conjunction with this system.
Conceptual Water Quality Management computations show a required
removal efficiency rate of 84% for an impervious area of 106,000 Square
Feet. The Application Plan proposes an area of 9-10,000 square feet to
filter runoff from the site.
Water and Sewer:
Page 7 of 22
Public water and sewer are available in the Crozet Growth area. A 12"
waterline is available onsite at Haden Place. An Existing fire hydrant is
located onsite on Haden Lane. An existing fire hydrant is located on
Killdeer Lane across from the site. It is anticipated with the Application
Plan that a new waterline will follow the connector road, teeing into both
existing lines and a hydrant will be located near the entrance of Haden
Place.
An 8" sanitary sewer line is located on Haden Lane and is available to
serve future hookups at Haden Place. An additional 8" sanitary line is
available on Killdeer lane. It is anticipated with the Application Plan that
a new sanitary sewer line, serving all proposed residences, will follow the
proposed alley and connect to the existing line on Haden Lane.

Part 2: The Code of Development
The narrative herein, including referenced tables and figures from the "HADEN PLACE
ZMA 2005-0007 Application Plan" with current revision date of February 5,2007
establish the Code of Development for the property and meet the requirements of Section
20A of the Zoning Ordinance. Proffers are provided as a separate document. The
Application Plan is a graphic depiction of the zoning district and the fOllowing
descriptions are to be provided as shown on this Plan. Where any discrepancy occurs
between this written Code and The Application Plan, this written Code shall take
precedence. In the event a conflict ever exists between this written Code and the
requirements of any applicable state or local ordinances, the state or local ordinances
shall take precedence.
Illustrative Plan:
The Illustrative Plan is a representation of the general fonn and massing of Haden Place.
Development of Haden Place shall be in general accord with the Illustrative Plan.
Significant features of the Illustrative Plan include:
1. Lower density detached residential development along the perimeter of
the district adjacent to existing residences,
2. Higher density attached residential development (with home
occupational uses) internal to the district,
3. Functional open space (with integrated tree preservation and
stormwater management) located between the development and
Summerford Lane to the south,
4. Rear-accessed parking (via private alleys) for all residential units.
5. And a mixture of at least 3 (three) types of residential units in the
district.
Page 8 of 22
General Development Plan:
The General Development Plan includes sheets A5.1 through A 7 of the Application Plan.
The Development of Haden Place as a district shall be in general accord with the graphic
representations of the General Development Plan. In addition to the infonnation
provided herein, the requirements of Section 20A.50fthe Albemarle County Zoning
Ordinance are provided on Sheets A5.! through A6.5, including the following
1. Permitted Uses By-Right,
2. Maximum allowable density,
3. Maximum allowable lot coverage (footprint of building I area oflot),
4. Maximum allowable height of structures,
5. Minimum allowable lot sizes,
6. Minimum allowable yard setbacks,
7. Location and requirements of Built- To Lines,
The Code of Development requirements shown on these sheets are not subject to the
"general accord" standard that applies to the physical layout of the improvements on the
Plan, pursuant to Section 8.5.5.3.
In addition, the General Development Plan proposes street sections for determining the
location and widths of the following: travel lanes, alleyways, parking lanes, parking bays,
landscape isle, medians, islands, rights-of-way, and access easements. It is anticipated
that final locations and dimensions of these elements of the street sections will be
determined with the approval of Road Plans, Utility Plans, and the Final Plat for the
development.
Where any commercial use is proposed, the commercial use shall be accessory to the
permitted residential use and shall be regulated by Section 5.2.2.1 of the Zoning
Ordinance. The intent of this provision is to allow limited, neighborhood-scale home
occupation ventures that would not alter the human scale of the residential district.
On street parallel parking shall be provided for each block in Haden Place, as permitted
by VDOT and the County Engineer.
The intent of the open space delineated in Block J of the General Development Plan is to
provide a substantial tree preservation of the existed wooded area on the site, onsite
stonnwater management for the development of Haden Place, and a pocket park that
integrates the development of Haden Place with the Ballard Fields townhomes across
Summerford Lane. The open space shall be designed to maximize pedestrian
accessibility and use through plantings and hardscaping. As future interconnectivity with
adjoining parcels is still being considered by County Planners; at the request of
Albemarle County, the open space area shown as Block J shall be dedicated for public
purpose and made available for vehicular and/or pedestrian connections to the adjoining
Ballard Fields Subdivision and/or for realignment of Killdeer Lane.

Land Use:
Residential Density (Section 20A.7)
Haden Place lies within Neighborhood 6 as identified on the Crozet Master Plan. The
site, along with the existing neighborhoods on Haden Lane and Killdeer Lane are further
identified as Neighborhood Village I Edge (CT3) from the Crozet Land Use and Place
Types Table. Residential uses recommended in the CT3 category include: Cottages,
Houses, Accessory Units and Live Work Units. The "Master Matrix" Crozet Place Types
and Design Guidelines recommended density is 3.5-4.5 units per acre with up to 6.5 units
per acre if accessory apartments are added for 50% of the residential stock.
As an R-2 district (existing zoning), 13 residential units are allowed on the site (20
utilizing bonus factors). The Crozet Master Plan recommends up to 24.1 residential units
(using 5.35 net acres) ifno accessory apartments are provided; and by incorporating
"accessory apartments", up to 34.8 residential units are recommended.
The Application Plan shows a total of 34 "for sale" residential units for Haden Place.
In requesting that 34 residential units (or 5.0 units per acre) be allowed in Haden Place,
the applicant shall provide three housing types, as follows:
14 SFD Village Homes (see supporting photographs in Part 3 of Code):
The larger residential units (typically 2,000 square feet and more) are placed along Haden
Lane and Killdeer Lane to provide consistency with the existing residential development
along these streets. The setbacks proposed in the Application Plan are actually greater
than the existing R-2 setbacks along these streets. While the side setbacks between these
homes are consistent with R-2 setbacks, there are no homes proposed adjacent to the
southern boundary and the homes adjacent to the northern boundary are shown with 20 ft
setbacks from the northern property line, which is twice that required in an R-2 district.
The single-family home footprints shown are variations of the Ashland, Bedford, and
Chatham models built in Wayland's Grant and Parkside Village. These vemacnlar-style
homes have deep front porches that wrap around on comer lots. The 8 homes on Haden
Lane have rear-loaded garages, which along with landscaping are oriented to screen the
rear of the interior townhomes and parking from the street. The six homes which front on
Killdeer lane have rear loaded, basement garages with additional room to park on aprons
behind the garages. The architectural style, colors, walkways and plantings of these
homes are consistent with Crozet's period of historic significance (c. 1870 to c. 1950).
6 SFD Cottages (see supporting photographs in Part 3 of Code):
The single-family cottages (typically less than 2,000 square feet) provide a new and
uniqne hOusing product for Albemarle County. The cottages and their lots are designed to
provide for-sale detached housing alternatives at a lower price-point in the growth area.
Page 10 of22
The architectural style, materials, colors, and landscaping of the cottages will blend with
the Townhomes and Village homes of Haden Place.
14 SFA Townhomes:
The 14 townhomes are intended to direct mass, density, height, fonn, streetscape, and
activity to the center of the site without overwhelming the plan. Two of the buildings
allow for 5 attached units while the third building allows for 4 attached units. The effect
of this massing is to prohibit "row-housing" that is not in character with the surrounding
neighborhood of Haden Lane and Killdeer Lane and to provide a greater ability to match
the architectural style of the surrounding neighborhood. While the Application Plan
stipulates the residential character of the street elevation, it is the intent of the Application
to provide the ability for first floor neighborhood scale workspace to be incorporated into
the design as home occupations. Of unique importance to the design of Haden Place is
the 90- ft separation of the Build-To Lines and the parallel parking and substantial tree
canopy between the buildings. At the northern property line, the 10,600 square foot
"open space buffer", along with the rear alley and driveways, effectively creates a 50-ft
setback for the 4-unit towuhomes at the top of Haden Place. Along with screening, this
creates a rear setback, which is 2 Y2 times that required in an R-2 district.
Open Space and Amenities: (Section 20A.9)
Three primary open spaces are provided, as shown on sheet Al of the Application Plan,
which integrate with the planned development and the surrounding community:
The I-~ acre passive pocket park, identified as Block J on the Application Plan, which
has an integrated stonowater management area, a picnic pavilion, sized to serve the needs
of the Haden Place residents, and blends the planned development with the higher density
Ballard Fields townhomes to the South. An approximately 20-ft strip of Ballard Fields
''Open Space" lies between this proposed park and Summerford Lane to the South. With
pennission from the adjacent landowner, this additional land will be incorporated into the
pocket park design. The pocket park will contain a tree preservation area, an oversized
biofilter with plantings, footpaths, sitting areas and similar features that will help it
become a pedestrian link to and from Old Trail, Haden Place, and downtown Croze!. As
the exact location of future interparceJ connections have not yet been detennined,
provisions for future dedications for connectivity at the request of the Albemarle County
Board of Supervisors have been made in the proffers and also noted on the Application
Plan.
On the Application Plan at the top of Haden Place is an approximately 110ft. by 90 ft.
"square" that is framed by the cottages and four of the townhomes. In the center of the
square is a "green" of approximately 60 ft diameter. While the larger park serves a more
public use to the local community, the square will serve as common open space to the
residents on Haden Place. The area might serve as a garden, a play area, a sitting area, or
some combination of these.
Page 11 of22
The 10,600 square lOOt "Open Space Buffer" at the North eud of the site creates a privacy
screen between existing neighbors to the North and the rear of the 4-unit townhomes as
shown on the Application Plan. Along with screening, this area might also serve as a
place to walk a dog, play, or garden. Adjacent to the 4-unit townhomes, in Blocks L and
M are located a playground area and a garden lot to serve the needs of the Haden Place
residents. The final design features of the playground, garden area, green, and pavilion
area will be detennined at the time of final site planning for Haden Place.
The pedestrian connectivity with Old Trail and downtown Crozet is further enhanced, as
there is another 1.5-acre park 800 feet south on Swnmerford Lane in Ballard Fields along
the way to Old Trail's Western Park, which is ~ mile south of Haden Place.
Historic Resources:
The existing c. 1882 vernacular-style farmhouse has been identified as historic (50 years
or older). Unfortunately, the house has been left vacant and has not been maintained for
many years. Original interior fixtures and detail have been removed and the overall
structure is in very poor condition. Renovation of the structure is not an option for the
applicant. While several of the existing trees around the homesite will need to be
removed to accommodate the proposed plan, the potential exists to preserve 3 or 4 of the
existing oak trees. The ability to preserve these trees is dependent on final road and
utility plans for Haden Lane. In addition, street trees, sidewalks, walkways, and front
yard landscaping are proposed throughout the site. Documentation of the historic
resources, in accordance with the Department of Historic Resources Reconnaissance
level survey standards will be provided as an addendum to this Code of Development, as
proffered.
Architectural and Landscape Standards:
The following Architectural and Lanscape guidelines will be applied to the buildings and
lots of Haden Place:
General Architectural Style:
The architectural style of Haden Place shall match the predominant style of the
Crozet residences from the late 19th and early 20th century. This "vernacular" Virginia
style is most evident in the shape and ornamentation of the late 19th century Victorian
homes and the eave and porch details of the early 20th century craftsman style homes.
Page 12 of22
Form, Massing and Proportion:
1. All residences in Blocks A and B shall have a fonnal porch facing the
adjoining street.
2. Haden Lane, Killdeer Lane, and Haden Place shall have a minimum of three
different house elevations built on each street front. This requirement is to
prevent the overuse of one architectural element on each of these streets.
3. To the greatest extent possible, garage doors shall not be visible from public
or private streets.
4. All first floors shall have 9' ceiling heights.
Materials and Color:
1. Vinyl siding is not pennitted in Haden Place. Masonry, wood, and
composites of wood and masonry are permitted as an exterior facrade

TREE PRESERVATION
& PROTECTION
@
Definition
Protection of desirable trees from mechanical and other injury during land disturbing and
construction activity.
Purpose
To ensure the survival of desirable trees where they will be effective for erosion and
sediment control, watershed protection, landscape beautification, dust and pollution control,
noise reduction, shade and other environmental benefits while the land is being converted
from forest to urban-type uses.
Conditions Where Practice Applies
Tree-inhabited areas subject to land disturbing activities.

Plannin~ Considerations
New development often takes place on tracts of forested land. In fact, building sites are
often selected because of the presence of mature trees. However, unless sufficient care is
taken and planning done in the interval between buying the property and completing
construction, much of this resource is likely to be destroyed. The property owner is
ultimately responsible for protecting as many trees as possible, with their understory and
ground cover. This responsibility is usually exercised by agents-the planners, designers and
contractors. It takes 20 to 30 years for newly planted trees to provide the benefits for which
we value trees so highly. Trees perform the following functions on a site:
1. Assist in stabilizing the soil and preventing erosion.
2. Help to decrease stormwater runoff through canopy interception and root
zone absorption.
3. Moderate temperature changes and provide shade.
4. Moderate the effects of sun and wind.
5. Provide buffers and screens against noise.
6. Filter pollutants from the air.
7. Help to remove carbon dioxide from the air and release oxygen.
8. Provide a haven for animals and birds, which help to control insect
populations.
9. Conserve and increase property values.
10. Provide psychological and aesthetic counterpoints to the man-made urban
setting.
Stresses of Construction
Trees may appear to be inanimate objects, but they are living organisms that are constantly
involved in the process of respiration, food processing, and growth. Construction activities
expose trees to a variety of stresses resulting in injury ranging from superficial wounds to
death. An understanding of these stresses is helpful in planning for tree protection.
1. Surface Impacts: Natural and man-related forces exerted on the tree above the
ground can cause significant damage to trees.
a. Wind damage - Removal of some trees from groups will expose those
remaining to greater wind velocities. Trees tend to develop anchorage where
III - 394
1992
3.38
it is most needed. Isolated trees develop anchorage rather equally all around,
with stronger root development on the side of the prevailing winds. The more
a tree is protected from the wind, the less secure is its anchorage. The result
of improper thinning is often wind-thrown trees. Selective removal in favor
of a single tall tree may also create a lightning hazard.
b. Excessive pruning - Unprotected trees are often "topped" or carelessly pruned
to prevent interference with utility wires or buildings. If too many branches
are cut, the tree may not be able to sustain itself. If the pruning is done
without considering the growth habit, the tree may lose all visual appeal. If
the branches are not pruned correctly, decay may set in.
c. Trunk damage - Tree trunks are often nicked or scarred by trucks and
construction equipment. Such superficial wounds provide access to insects
and disease.
2. Root Zone Impacts: Disturbing and delicate relationship between soil, roots, and the
rest of the tree can damage or kill a tree. The roots of an existing tree are
established in an area where essential materials (water, oxygen, and nutrients) are
present. The mass of the root system is the correct size to balance the intake of
water from the soil with the transpiration of water from the leaves.
a. Raising the grade as little as 6 inches can retard the normal exchange of air
and gases. Roots may suffocate due to lack of oxygen, or be damaged by
toxic gases and chemicals released by soil bacteria.
b. Raising the grade may also elevate the water table. This can cause drowning
of the deeper roots.
c. Lowering the grade is not usually as damaging as raising it. However, even
shallow cuts of 6 to 8 inches will remove most of the topsoil, removing some
feeder roots and exposing the rest to drying and freezing.
d. Deep cuts may sever a large portion of the root system, depriving the tree of
water and increasing the chance of wind-throw.
e. Lowering the grade may lower the water table, inducing drought. This is a
problem in large roadway cuts or underdrain installations.
f. Trenching or excavating through a tree's root zone can eliminate as much as
40 percent of the root system. Trees suffering such damage usually die within
2 to 5 years.
g. Compaction of the soil within the drip line (even a few feet beyond the drip
line) of a tree by equipment operation, materials storage, or paving can block
off air and water from roots.
III - 395
1992
3.38
h.
Construction chemicals or refuse disposed of in the soil can change soil
chemistry or be toxic to trees. Most damage. to trees from construction
activities is due to the invisible root zone stresses.
Design Criteria
No formal design is required. However, in planning for the development of a wooded site
where some trees will be preserved, a number of criteria must be considered.
Selecting Trees to be Retained
The proper development of a wooded site requires completion of a plan for tree
preservation before clearing and construction begins. Trees should be identified by species,
and located on a topographical map, either as stands or as individuals, depending on the
density and value of the trees. Base decisions on which trees to save on the following
considerations:
1. Life expectancy and present age: Preference should be given to trees with a
long life span, such as white oak, beech, and maple. Long-lived specimens.
that are past their prime may succumb to the stresses of construction, so
smaller, younger trees of desirable species are preferred; they are more
resilient and will last longer. However, if the cost of preservation is greater
than the cost of replacement with a specimen of the same age and size,
replacement may be preferred.
2. Health and disease susceptibility: Check for scarring caused by fire or
lightning, insect or disease damage, and rotted or broken trunks or limbs.
Pest- and pollution-resistant trees are preferred.
3. Structure: Check for structural defects that indicate weakness or reduce the
aesthetic value of a tree: trees growing from old stumps, large trees with
overhanging limbs that endanger property, trees with brittle wood (such as
silver maple), misshapen trunks or crowns, and small crowns at the top of tall
trunks. Open grown trees often have better form than those grown in the
woods. Trees with strong tap or fibrous root systems are preferred to trees
with weak rooting habits.
4. Cleanliness: Some trees such as elm and black locust are notoriously "dirty",
dropping twigs, bark, fruit, or plant exudates. A clean tree is worth more than
a dirty one. Trees which seed prolifically or sucker profusely are generally
less desirable in urban areas. Thornless varieties are preferred.
5. Aesthetic values: Handsome bark and leaves, neat growth habit, fine fall
color, and attractive flowers and fruit are desirable characteristics. Trees that
III - 396
1992
3.38
provide interest during several seasons of the year enhance the value of the
site.
6. Comfort: Trees help relieve the heat of summer and buffer strong winds
throughout the year. Summer temperatures may be 10 degrees cooler under
hardwoods than under conifers. Deciduous trees drop their leaves in winter,
allowing the sun to warm buildings and soil. Evergreens are more effective
wind buffers.
7. Wildlife: Preference should be given to trees that provide food, cover, and
nesting sites for birds and game.
8. Adaptability to the proposed development:
a. Consider the mature height and spread of trees; they may interfere
with proposed structures and overhead utilities. Roots may interfere
with walls, walks, driveways, patios, and other paved surfaces; or water
lines, septic tanks, and underground drainage.
b. Trees must be appropriate to the proposed use of the development;
select trees which are pollution-tolerant for high-traffic and industrial
areas, screen and buffer trees for noise or objectionable views, salt-
tolerant species for areas exposed to deicing salts or ocean spray.
c. Consider location of landfills. Gases generated in them can travel long
distances underground, to injure distant trees. Choose species tolerant
of anaerobic soil conditions.
d. Determine the effect of proposed grading on the water table. Grading
should not take place within the drip line of any tree to be saved.
9. Survival needs of the tree: Chosen trees must have enough room to develop
naturally. They will be subject to injury from increased exposure to sunlight,
heat radiated from buildings and pavement, and wind. It is best to retain
groups of trees rather than individuals. As trees mature, they can be thinned
gradually.
10. Relationship to other trees: Individual species should be evaluated in relation
to other species on the site. A species with low value when growing among
hardwoods will increase in value if it is the only species present. Trees
standing alone generally have higher landscape value than those in a wooded
situation. However, tree groups are much more effective in preventing
erosion and excess stormwater runoff.
III - 397
1992
3.38
Site Planning for Tree Prote.ction
1. If lot size allows, select trees to be saved before siting the building. No tree should
be destroyed or altered until the design of buildings and utility systems is final.
2. Critical areas, such as flood plains, steep slopes, and wetlands, should be left in their
natural condition or only partially developed as open space.
3. Locate roadways to cause the least damage to valuable stands. Follow original
contours, where feasible, to minimize cuts and fills.
4. Minimize trenching by locating several utilities in the same trench. Excavations for
basements and utilities should be kept away from the drip line of trees.
5. Construction material storage areas and worker parking should be noted on the site
plan, and located where they will not cause compaction over roots.
6. When retaining existing trees in parking areas, leave enough ground ungraded
beyond the drip line of the tree to allow for its survival.
7. Locate erosion and sediment control measures at the limits of clearing and not in
wooded areas, to prevent deposition of sediment within the drip line of trees being
preserved. Sediment basins should be constructed in the natural terrain, if possible,
rather than in locations where extensive grading and tree removal will be required.
Specifications
1. Groups of trees and individual trees selected for retention shall be accurately located
on the plan and designated as "tree(s) to be saved." Individual specimens that are
not part of a tree group shall also have their species and diameter noted on the plan.
2. At a minimum, the limits of clearing shall be located outside the drip line of any tree
to be retained and, in no case, closer than 5 feet to the trunk of any tree (Plate 3.38-
1).
3. Markin~: Prior to construction and before the preconstruction conference, individual
trees and stands of trees to be retained within the limits of clearing shall be marked
at a height visible to equipment operators. According to the Virginia Department
of Forestry, a diagonal slash of brightly colored paint approximately 8 to 10 inches
in length is a common practice in areas where an accidental or purposeful alteration
of the proper markings is a concern. In most situations, such as an area which is
supposed to receive formal landscaping, a surveyor's ribbon or a similar material
applied at a reasonable height encircling the tree will suffice.

4. Pre-Construction Conference: During any preconstruction conference, tree
preservation and protection measures should be reviewed with the contractor as they
apply to that specific project.
5. Equipment Operation and Stor~ie: Heavy equipment, vehicular traffic, or stockpiles
of any construction materials (including topsoil) shall not be permitted within the
drip line of any tree to be retained. Trees being removed shall not be felled, pushed
or pulled into trees being retained. Equipment operators shall not clean any part of
their equipment by slamming it against tbe trunks of trees to be retained.
6. Fires: Fires sball not be permitted within 100 feet from the drip line of any trees to
be retained. Fires shall be limited in size to prevent adverse effects on trees, and
kept under surveillance.
7. Storaie and Di&posal of Toxic Materials: No toxic materials shall be stored closer
than 100 feet to the drip line of any trees to be retained. Paint, acid, nails, gypsum
board, wire, chemicals, fuels, and lubricants shall not be disposed of in such a way
as to injure vegetation.
III - 399
b. Board Fence _ Board fencing consisting of 4-inch square posts set securely in
the ground and protruding at least 4 feet above the ground shall be placed at
the limits of clearing with a minimum of two horizontal boards between posts.
If it is not practical to erect a fence at the drip line, construct a triangular
fence nearer the trunk. The limits of clearing will still be located at the drip
line, since the root zone within the drip line will still require protection.
1992 3.38
8. Fencing and Armoring (Plate 3.38-2): Any device may be used which will effectively
protect the roots, trunk and tops of trees retained on the site. However, trees to be
retained within 40 feet of a proposed building or excavation shall be protected by
fencing. Personnel must be instructed to honor protective devices. The devices
described are suggested only, and are not intended to exclude the use of other
devices which will protect the trees to be retained.
a. Snow Fence _ Standard 40-inch high snow fence shall be placed at the limits
of clearing on standard steel posts set 6 feet apart.
c. Cord Fence _ Posts with a minimum size of 2 inches square or 2 inches in
diameter set securely in the ground and protruding at least 4 feet above the
ground shall be placed at the limits of clearing with two rows of cord 1/4-inch
or thicker at least 2 feet apart running between posts with strips of colored
surveyor's flagging tied securely to the string at intervals no greater than 3
feet.
d. Plastic Fencing - 40-inch high "international orange" plastic (polyethylene) web
fencing secured to conventional metal 'T' or "V" posts driven to a minimum
depth of 18 inches on 6-foot minimum centers shall be installed at the limits
of clearing. The fence should have the following minimum physical qualities:
Tensile yield:
Average 2,000 lbs. per 4-foot width (ASTM D638)
Ultimate
tensile yield:
Average 2,900 lbs. per 4-foot width (ASTM D638)
Elongation
at break (%):
Greater than 1000% (ASTM D638)
Chemical
resistance:
Inert to most chemicals and acids
e. Earth Berms - Temporary earth berms shall be constructed according to
specifications for a TEMPORARY DIVERSION DIKE (Std. & Spec. 3.9)
with the base of the berm on the tree side located along the limits of clearing.
Earth berms may not be used for this purpose if their presence will conflict
with drainage patterns.

f.
Additional Trees - Additional trees may be left standing as protection
between the trunks of the trees to be retained and the limits of clearing.
However, in order for this alternative to be used, the trunks of the trees in the
buffer must be no more than 6 feet apart to prevent passage of equipment
and material through the buffer. These additional trees shall be reexamined
prior to the completion of construction and either be given sufficient
treatment to ensure survival or be removed.
g.
Trunk Armorin~ - As a last resort, a tree trunk can be armored with burlap
wrapping and 2-inch studs wired vertically no more than 2 inches apart to a
height of 5 feet encircling the trunk. If this alternative is used, the root zone
within the drip line will still require protection. Nothing should ever be
nailed to a tree.
Fencing and armoring devices shall be in place before any excavation or grading is
begun, shall be kept in good repair for the duration of construction activities, and
shall be the last items removed during the final cleanup after the completion of the
project.
9. Raisin~ the ~rade: When the ground level must be raised around an existing tree or
tree group, the following considerations shall be made and steps taken to adequately
care for the affected tree.
a. A well may be created around the tree(s) slightly beyond the drip line to
retain the natural soil in the area of the feeder roots (Plate 3.38-3).

b.
In the case of an individual tree, when the above alternative is not practical
or desirable, the following method is recommended to ensure survival of the
tree (Plate 3.38-4).
1) Before making the fill, remove the green vegetation, sod, leaf litter,
and other organic matter from beneath the tree or trees to a distance
of 3 feet beyond the drip line and loosen the surface soil to a depth of
approximately 3 inches without damaging the roots.
2) Apply fertilizer in the root area of the tree to be retained. Fertilizer
formulations and application rates and methods shall conform to the
guidelines provided in Table 3.38-A.
3) The dry well shall be constructed so as to allow for tree trunk diameter
growth. A space of at least 1 foot between the tree trunk and the well
wall is adequate for large, old, slow-growing trees. Clearance for
younger trees shall be at least 2 feet.
4) The well shall be high enough to bring the top just above the level of
the proposed fill. The well wall shall taper slightly away from the tree
trunk at a rate of 1 inch per foot of wall height.
5) The well wall shall be constructed of large stones, brick, building tile,
concrete blocks, or cinder blocks with care being taken to ensure that
ample openings are left through the wall of the well to allow for free
movement of air and water. Mortar shall only be used near the top of
the well and only above the porous fill.
6) Drain lines composed of 4-inch, high-quality drain tiles shall begin at
the lowest point inside the well and extend outward from the tree
trunk in a wheel-and-spoke pattern with the trunk as the hub. These
radial drain lines shall slope away from the well at a rate of 1/8 inch
per foot. The circumferential line of tiles should be located beneath
the drip line of the tree. Vertical tiles or pipes shall be placed over
the intersections of the two tile systems if a fill of more than 2 feet is
contemplated. These vertical tiles shall be held in place with stone fill.
Tile joints shall be tight. A few radial tiles shall extend beyond each
intersection and shall slope sharply downward to ensure good drainage.
7) Tar paper or its approved equivalent shall be placed over the tile
and/ or pipe joints to prevent clogging, and large stone shall be placed
around and over drain tiles and/or pipes for protection.

8)
A layer of 2- to 6-inches of stone shall be placed over the entire area
under the tree from the well outward at least as far as the drip line.
For fills up to 2-feet deep, a layer of stone 8- to 12-inches thick should
be adequate. A thicker layer of this stone, not to exceed 30 inches,
will be needed for deeper fills.
9)
A layer of 3j4-inch to 1-inch stone covered by straw, fiber-glass mat or
a manufactured filter fabric shall be used to prevent soil from clogging
the space between stones. Cinders shall not be used as fill material.
10)
Filling shall be completed with porous soil such as topsoil until the
desired grade is reached. This soil shall be suitable to sustain specified
vegetation.
11)
To prevent clogging of the drain lines, crushed stone shall be placed
inside the dry well over the openings of the radial tiles. Vertical tiles
shall also be filled with crushed rock and may also be covered with a
screen.
12)
To prevent anyone from falling into the dry well and leaves and debris
from accumulating there, the area between the trunk and the well wall
shall either be covered by an iron grate or filled with a 50-50 mixture
of crushed charcoal and sand. (This will also prevent rodent
infestation and mosquito breeding.)
c. Where water drainage through the soil is not a problem, coarse gravel in the
fill may be substituted for the tile. This material has sufficient porosity to
ensure air drainage. Instead of the vertical tiles or pipes in the system, stones,
crushed rock, and gravel may be added so that the upper level of these porous
materials slants toward the surface in the vicinity below the drip line (Plate
3.38-5).
d. Raising the grade on only one side of a tree or group of trees may be
accomplished by constructing only half of one of these systems.
10. Lowerin~ the grade: Trees shall be protected from harmful grade cuts by the
construction of a tree wall (Plate 3.38-6).
a. Following excavation, all tree roots that are exposed and/or damaged shall be
trimmed cleanly, painted with tree paint, and covered with moist peat moss,
burlap, or other suitable material to keep them from drying out.
b. The wall shall be constructed of large stones, brick, building tile, or concrete
block or cinder block in accordance with the detail in Plate 3.38-6.

e. Prune the tree crown, reducing the leaf surface in proportion to the amount
of root loss.
f. Provide drainage through the wall so water will not accumulate behind the

11. Trenchin~ and Tunnellin~:
a. Trenching shall be done as far away from the trunks of trees as possible,
preferably outside the branches or crown spreads of trees, to reduce the
amount of root area damaged, or killed by trenching activities.
b. Wherever possible, trenches should avoid large roots or root concentrations.
This can be. accomplish~d by curving the trench or by tunnelling under large
roots and areas of heavy root concentration.
c. Tunnelling is more expensive initially, but it usually causes less soil
disturbance and physiological impact on the root system (Plate 3.38-7). The
extra cost may offset the potential cost of tree removal and replacement
should the tree die.

Tunnelling is almost always preferred over the trenching method. The tunnel
should be 18 inches or greater below the ground surface and should not be
located under the center of the tree (an off-center tunnel has the least impact
on the roots).
d. Roots shall not be left exposed to the air. They shall be covered with soil as
soon as possible or protected and kept moistened with wet burlap or peat
moss until the trench or tunnel can be filled.
e. The ends of damaged and cut roots shall be cut off smoothly and protected
by painting promptly with a tree-wound dressing.
f. Trenches and tunnels shall be filled as soon as possible. Air spaces in the soil
shall be avoided by careful filling and tamping.
g. Peat moss or other suitable material shall be added to the fill material as an
aid to inducing and developing new root growth.
h. The tree shall be mulched and fertilized to conserve moisture, stimulate new
root growth, and enhance general tree vigor.
i. If a large amount of the root system has been damaged and killed, the crown
leaf surface shall be proportionately reduced to balance the reduced root
system. This may be accomplished by pruning 20 to 30 percent of the crown
foliage. If roots are cut during the winter, pruning shall be accomplished
before the next growing season. If roots are cut during the growing season,
pruning shall be done immediately.
12. Removal and Re.,placement of Dama~ed Trees: Should a tree intended and marked
to be retained be damaged seriously enough that survival and normal growth are not
possible, the tree shall be removed. If replacement is desirable and/or required, the
replacement tree shall be of the same or similar species, 2-inch to 2~-inch
(minimum) caliper balled and burlapped nursery stock. However, today, with the aid
of a "tree spade," the same caliper tree may be required as a replacement.
13. Clean-Up: Clean-up after a construction project can be a critical time for tree
damage. Trees protected throughout the development operation are often destroyed
by carelessness during the final clean-up and landscaping. Fences and barriers shall
be removed last, after everything else is cleaned-up and carried away.
14. Maintenance: In spite of precautions, some damage ~o protected trees may occur.
In such cases, the following maintenance guidelines should be followed:
a. Soil Aeration - If the soil has become compacted over the root zone of any
tree, the ground shall be aerated by punching holes with an iron bar. The bar
shall be driven 1-foot deep and then moved back and forth until the soil is
III - 410
3.38
1992
loosened. This procedure shall be repeated every 18 inches until all of the
compacted soil beneath the crown of the tree has been loosened.
b. Repair of Dama~e
1) Any damage to the crown, trunk, or root system of any tree retained
on the site shall be repaired immediately.
2) Whenever major root or bark damage occurs, remove some foliage to
reduce the demand for water and nutrients. '
3) Damaged roots shall immediately be cut off cleanly inside the exposed
or damaged area. Cut surfaces shall be painted with approved tree
paint, and moist peat moss, burlap, or top-soil shall be spread over the
exposed area.
4) To treat bark damage, carefully cut away all loosened bark back into
the undamaged area, taper the cut at the top and bottom, and provide
drainage at the base of the wound (Plate 3.38-8).
5) All tree limbs damaged during construction or removed for any other
reason shall be cut off above the collar at the preceding branch
junction (Plate 3.38-8).
6) Care for serious injuries shall be prescribed by a forester or a tree
specialist.
c. Fertilization: Broadleaf trees that have been stressed or damaged shall
receive a heavy application of fertilizer to aid their recovery.
1) Trees shall be fertilized in the late fall (after October 1) or the early
spring (from the time frost is out of the ground until May 1). Fall
applications are preferred, as the nutrients will be made available over
a longer period of time.
2) Fertilizer shall be applied to the soil over the feeder roots (see Plate
3.38-9). In no case should it be applied closer than 3 feet to the trunk.
The root system of conifers extends some distance beyond the drip
line. Increase the area to be fertilized by one fourth the area of the
crown.
3) Fertilizer shall be applied using approved fertilization methods and
equipment.
