SECTION 5.18- LANDSCAPE STANDARDS AND STREET TREES
Sufficient landscaping shall be provided as part of the subdivision
design. It shall be conceived in a total pattern throughout the site
integrating the various elements of the site design, preserving and enhancing
the particular identity of the site, and eventually creating a pleasing site
5.18.02 Landscaping Plan
For major subdivisions the developer shall provide a landscape plan
prepared by a state licensed landscape architect or other qualified
professional. The Commission retains the right to require a plan from a
licensed landscape architect. The plan should emphasize the retention of
existing vegetation and native plantings.
5.18.03 Site Grading
To the maximum extent practicable site grading shall be minimized and existing
topography and natural vegetation shall be retained.
5.18.04 Topsoil Preservation
Topsoil moved during the course of construction shall be redistributed on all
regraded surfaces so as to provide at least (4) four inches of even cover to all
disturbed areas of the development and shall be stabilized by seeding or
planting. The developer is requested to use the publication, Connecticut
Guidelines for Soil Erosion and Sediment Control (latest edition), as
amended from time to time, as a tool in adhering to this section.
If four (4) inches of topsoil did not originally exist on the site the developer
shall retain all topsoil on site and may be required to bring in additional top
soil. Topsoil shall not be removed from open space or forested of any topsoil
from the site the developer shall notify the Zoning Enforcement Officer.
5.18.05 Removal of Debris
All stumps and other tree parts, litter, brush, weeds, excess or scrap building
materials or other debris shall be disposed of in accordance with the law. No
tree stumps or portions of tree trunks or limbs shall be buried anywhere in the
development. No building materials shall be buried anywhere in the
development. All dead or dying trees, standing or fallen, shall be removed
from the site except in open space/conservation areas where some dead or dying
non hazardous tress may be left for wildlife habitat. If trees and limbs are
reduced to chips, they may be used as mulch in landscaped areas or for soil
stabilization, subject to approval by the Zoning Enforcement Officer. (Amended
5.18.06 Protection of Existing Plantings
Maximum effort should be made to save fine specimens and clusters of native
trees. No material or temporary soil deposits shall be placed within four (4)
feet of shrubs or under the dripline of trees designated on the landscape plan
to be retained. Protective barriers or tree wells shall be installed
around each plant and/or group of plants that are to remain on the site.
Protective barriers should be outside of the dripline. Barriers shall not
be supported by the plants they are protecting but shall be
self-supporting. They shall be a minimum of three (3) feet high and
constructed of a durable material that will last until construction is
completed. Snow fences and silt fences are acceptable methods of
protecting trees during the construction process are available from the
Environmental Planner/Planning and Zoning Department.
5.18.07 Slope Plantings
Landscaping of all cuts and fills and/or terraces shall be sufficient to
prevent erosion, and all roadway slopes steeper than one (1) foot vertically to
three (3) feet horizontally shall be planted with ground cover appropriate for
the purpose and for soil conditions, water availability, and environment.
Buffering shall provide a year-round visual screen in order to minimize adverse
impacts. It shall include but not be limited to fencing, evergreens, berms,
rocks, boulders, mounds, or combinations thereof to achieve the same objectives.
When required. Every development shall provide sufficient buffering
when topographical or other barriers do not provide reasonable screening and
when the Commission determines that there is a need (1) to shield neighboring
properties from any adverse external effects of a development; or (2) to shield
the development from negative impacts of adjacent uses such as streets,
railroads or changes in land use. In high density developments, when
building design and setting do not provide privacy, the Commission may require
landscaping, fences, or walls to screen dwelling units for privacy.
Buffers shall be measured from side and rear property lines, excluding
- Amount Required
- Where more intensive land uses abut
less-intensive uses, a buffer strip (fifteen (15) feet) in width shall be
- Parking lots, garbage collection and utility areas, and loading
and unloading areas should be screened around their perimeters by a buffer strip
a minimum of (five (5) feet) wide.
- Where residential subdivisions abut
higher-order streets (collectors or arterials), adjacent lots shall front on
lower-order streets (local), and a landscaped buffer area shall be provided
along the property line abutting the higher order street. The buffer strip shall
be a minimum of fifteen (15) feet wide or wider where necessary for the
health and safety of the residents. It shall include both trees and shrubs.
Design. Arrangement of plantings in buffers shall provide maximum
protection to adjacent properties and avoid damage to existing plant material.
Possible arrangements including planting in parallel, serpentine, or broken
rows. If planted berms are used, the minimum top width shall be four (4) feet,
and the maximum side slope shall be 2:1.
- Planting specifications.
Plant materials should be sufficiently large and planted in such a fashion that
a year-round screen at least eight (8) feet in height shall be produced within
three (3) growing seasons. All plantings shall be installed according to
accepted horticultural standards.
5.18.09 Shading and Ornamental Trees
The developer is encouraged to retain significant trees along the street and
in the front yards; where no trees exist the developer shall plant on both sides
of the street shade trees with a minimum of two and one half (2.5) to three (3)
inch caliper spaced one (1) for every fifty (50) feet maximum of street
frontage. Trees shall be selected and planted in order to adhere to the
- on the property and a minimum of 5 feet from the front
- 10 feet from hydrants utility poles and street lights;
feet from driveways;
- minimum of 5 feet from underground utilities;
- 25 feet
between small trees
- 35 feet between medium trees; and
- 50 feet between large trees.
Small and medium non-ornamental trees of suitable species and
size may be substituted for shade trees subject to the approval of the Director
The developer shall be responsible for taking adequate legal
safeguards to insure that the developer retains the right to enter upon any lot
within the subdivision to complete all required trees planting and all other
In major subdivisions the developer shall provide for a
separate landscape bond and all trees shall be planted prior to the final
release of the performance or landscape bond.
5.18.10 Boulevard and Center Island Landscaping
On any thoroughfare requiring a center island, such as a boulevard, a landscape
plan of such island shall be submitted as part of the overall landscape
plan. Plantings and landscaping requiring a minimum amount of maintenance
and that are salt tolerant shall be proposed for center islands and shall
conform to restrictions specified for sight distance. An acceptable fabric
landscape weed barrier shall be used on all such center islands.
5.18.11 Maintenance of Buffers, Shade and Ornamental Trees
Trees and other plantings shall be maintained by the developer until the
final release of the bond. Trees shall be watered regularly and in a
manner appropriate for the specific plant species through the first growing
season, and dead and dying plants shall be replaced by the developer during the
next planting season. During construction no temporary buildings,
structures, storage of materials, or parking of equipment shall be permitted
under the drip line of any tree or within any buffer area. Buffer areas shall be
maintained, protected and kept free of all debris, rubbish, weeds, and tall
