[Ord. No. 659 §1, 5-2-2011]
The purpose of this portion of the Strafford Zoning Ordinance is to ensure a minimum level of open space, bufferyard and green area as an integral part of new development.
[Ord. No. 659 §1, 5-2-2011]
A. 
The objectives that this landscaping, screening and open space ordinance intends to accomplish:
1. 
Landscaping would enhance the environmental and visual character of the community.
2. 
Green space requirements preserve and stabilize the area's ecological balance by establishing a healthier environment.
3. 
Green areas help to mitigate the negative effects of air and noise pollution by using plants as buffers.
4. 
Bufferyard requirements are designed to ameliorate nuisances between certain adjacent zoning districts or land uses. Bufferyard functions to eliminate or minimize large changes in scale and potential nuisances such as dirt, litter, noise, glare of lights, unsightly buildings, parking areas or signs.
5. 
Landscaping should be an integral part of a development — not an afterthought. This Chapter is designed to promote high quality developments, protect property values and public investment in our community.
[Ord. No. 659 §1, 5-2-2011]

If the provisions of this Chapter conflict with other ordinances or regulations, the more stringent limitation or requirement shall govern or prevail to the extent of the conflict.
[Ord. No. 659 §1, 5-2-2011]
Approval for a building permit, preliminary plat or minor subdivision plat application is handled according to the procedures outlined in Article IV, Permits and Final Plat Approval. Each type of application requires the submittal of appropriate site plans or construction plans.
[Ord. No. 659 §1, 5-2-2011]
A. 
The following information is required on site plans for staff to review for compliance with this Chapter.
1. 
Location, general type, and quality of existing vegetation, including specimen trees;
2.

[Ord. No. 659 §1, 5-2-2011]
Each development is required to address all three (3) areas in the landscaping plan as it pertains to the particular site. The landscaping plan must include plantings and green space along all street rights-of-way, between lots with adjacent parking lots and also within the interior of the parking areas as the requirements apply to the individual site. The text diagrams below explain the options that the application has for the site. Exemptions from these requirements are addressed in this Article, Section 400.615.
[Ord. No. 659 §1, 5-2-2011]
A. 
The landscaped street buffer serves two (2) primary purposes: when a parking lot is located adjacent to a public right-of-way, a strip of landscaping may shield views of parked cars to passing motorists and pedestrians, and it establishes coordination among architecturally diverse buildings which creates a pleasing, harmonious appearance along the roadway.
B. 
The site plans for any development, other than those exempt in Section 400.615, must show a landscaped street buffer along all public rights-of-way. The applicant may chose among five (5) options illustrated below, choosing one (1) or a combination of several to meet the particular site constraints of the development.
Option 1: A minimum buffer of ten (10) feet in width, planted with a minimum of one (1) shade tree and seven (7) shrubs per fifty (50) linear feet of street frontage.
400_0001a.tif
Street frontage
Option 2: Earth berms, at least two and one-half (2.5) feet higher than the finished elevation of the parking lot, planted with a minimum of one (1) shade tree and three (3) shrubs per fifty (50) linear feet of street frontage, with no set dimension.
400_0001b.tif
105' street frontage
Option 3: A six (6) foot landscaped street buffer with three (3) feet of fall that includes a minimum of one (1) shade tree and three (3) shrubs per fifty (50) feet of linear street frontage.
400_0002a.tif
6' landscaped strip
Option 4: A three (3) foot high wall made of brick, stone, or finished concrete along with a four (4) foot buffer area including one (1) shade tree per fifty (50) feet of linear street frontage.
400_0002b.tif
Landscaped strip
Option 5: A landscaped buffer area with existing woodlands maintained in a twenty-five (25) foot strip along the street frontage.
400_0003.tif
[Ord. No. 659 §1, 5-2-2011]
A. 
The parking lot landscaping requirements serves several purposes: it provides necessary green space to give relief to expansive parking areas with nothing but asphalt, and trees provide shade and serve as windbreaks. Planting islands assist with vehicular circulation.
B. 
The site plan for any development, other than those exempt in Section 400.615., must show interior parking lot landscaping. A sliding scale to determine the amount of green area per lot has been included in order for the applicant to include these landscaping requirements as an integral part of the site development.
Total Area of Parking Lot (excluding building and interior planting islands)
Percent of Total Area of Lot For Interior Planting Areas (including the street frontage buffer, perimeter strip and other travel lanes)
3,000 — 49,999 square feet
5%
50,000 — 149,000 square feet
8%
150,000 square feet or larger
10%
C. 
The diagram in Subsection (D) illustrates what areas of the vehicle accommodation area are considered when determining the total area of the parking lot. The square footage of all areas within the parking lot's perimeter are counted, including the planting islands required, curbed areas, corner lots, parking spaces and all interior driveways and aisles except those with no parking spaces located on either side. Landscaped areas outside the parking lot may not be used to meet the interior-planting requirement. The total amount of green space for the interior lot is determined by figuring five percent (5%), eight percent (8%), or ten percent (10%) of the total parking lot area as explained above.
D. 
Planting islands are required as a part of the green space percentage in the interior parking lot area. The diagram below illustrates the parking island dimensions. The dimensions of a parking island must be nine (9) feet by nineteen (19) feet, the same as a parking space, and must be curbed to protect the landscaping and trees. One (1) parking island is required for every fifteen (15) parking spaces determined for that use group from Article XVII. If thirteen (13) or more spaces remain, a parking island is required. The planting island must be evenly spaced among the parking spaces in the lot and serve as vehicular circulating whenever possible. In parking lots over one hundred fifty thousand (150,000) square feet, the number of parking islands can be reduced but the total square footage of green space must remain according to the requirements.
400_0004.tif
E. 
Trees are required to be planted in the interior parking area to offer shading from the heat and sun. One (1) tree per planting island is required for the interior parking area with the balance planted in grass or other vegetation. These trees must be planted within the island and a four (4) foot clearance should be left for car doors to open from the adjacent parking space.
F. 
Plant materials at vehicular entrances should be located so as to maintain safe sight distances and protect from vehicular lubricants or fuels.
[Ord. No. 659 §1, 5-2-2011]
A. 
Perimeter landscaping requirements define parking areas and prevent two (2) adjacent lots from becoming one (1) large expanse of paving. The diagram below illustrates this concept. At minimum, a five (5) foot landscaped strip is required along the side and rear lot lines of a development. One (1) tree and three (3) shrubs are required per fifty (50) linear feet of the perimeter. This perimeter-landscaping strip would not be in addition to the landscaped street frontage buffer required in Section 400.640.
400_0005.tif
B. 
The perimeter-landscaping requirement does not preclude the need for vehicular access to be provided between lots.
C. 
The five (5) foot perimeter strip is required for each development regardless if one is already in place from an adjacent, developed lot.
D. 
No pavement may extend within five (5) feet of the property line on any lot unless it is included with an ingress/egress location.
[Ord. No. 659 §1, 5-2-2011]
A. 
Standards have been established for installation of all plant materials within the City of Strafford. These requirements must be followed in order to receive approval of the site work and final occupancy or approval of the development. The City Administrator or other person designated by him has the authority to deny the issuance of a final occupancy permit until landscaping is installed according to the requirements of this Chapter and to the satisfaction of the site inspector.
B. 
Temporary occupancy permits may be issued by the Building Inspector for weather-related delays in the completion of a project. The builder must request a final inspection and make every attempt to finish the project and provide a time frame for completion that both parties must agree upon.
[Ord. No. 659 §1, 5-2-2011]
A. 
Trees shall not be placed where they interfere with site drainage or where they shall require frequent pruning in order to avoid interference with overhead power lines. A minimum of seventy-five percent (75%) of all required trees shall be shade trees.
B. 
Immediately upon planting, trees shall be a minimum of eight (8) feet tall and shall have a minimum caliper (widest width of trunk) of two (2) inches.
C. 
When more than ten (10) trees are to be planted to meet the requirements of this Chapter, a mix of species shall be provided. The number of species to be planted shall vary according to the overall number of trees required to be planted. The minimum number of species to be planted is listed in the table below. Species shall be planted in proportion to the required mix. This species mix shall not apply to areas of vegetation required to be preserved by law.
Required Species Mix Required Number of Trees
Minimum Number of Species
11 — 20
2
21 — 30
3
31 — 40
4
41+
5
D. 
Hedges, where required, shall form a solid continuous visual screen of at least three (3) feet in height immediately upon planting and shall be spaced eighteen (18) inches on center. Hedge plantings shall be maintained so as not to exceed a height of six (6) feet.
[Ord. No. 659 §1, 5-2-2011]
A. 
All interior landscaped areas not dedicated to trees or to preservation of existing vegetation shall be landscaped with grass, ground cover, shrubs, or other appropriate landscape treatment. Gravel or other pavement shall not be considered appropriate landscape treatment.
B. 
Safe sight distances at intersections and points of access must be maintained.
C. 
Except as provided below, all landscape areas at the front line of off-street parking spaces may be protected from encroachment or intrusion of vehicles through the use of wheel stops. Wheel stops shall have a minimum height of six (6) inches above finished grade of the parking area. Wheel stops shall be properly anchored and shall be continuously maintained in good condition by the property owner. Wheel stops shall not be placed in locations of anticipated intense pedestrian traffic.
D. 
Trees and other vegetation shall be planted in soil and climatic conditions which are appropriate for their growth habits. Plants used in the landscape design shall to the greatest extent be:
1. 
Appropriate to the conditions in which they are to be planted;
2. 
Have non-invasive growth habits;
3. 
Encourage low maintenance, high-quality design; and
4. 
Be otherwise consistent with the intent of this Chapter.
E. 
Replacement requirements for vegetation that is required to be planted or preserved by this Chapter shall be replaced with equivalent vegetation if it is not living within one (1) year of issuance of a certificate of occupancy. Preserved trees for which credit was awarded, but which subsequently die, shall be replaced by the requisite number of living trees according to the standard set forth in this Chapter.
[Ord. No. 659 §1, 5-2-2011]
A. 
The City Administrator or a person designated by him has the authority to enforce the requirements of this Chapter. Final occupancy permits and/or final plats will be held for those who fail to complete landscaping requirements. Once approved, the applicant is required to guarantee the plants for one (1) year or the owner must replace them. The property owner will maintain all trees and vegetation.
B. 
Temporary occupancy permits may be given to tenants from November first (1st) to March first (1st) if inclement weather delays completion of a project. These requests must be approved by the City Administrator.
[Ord. No. 659 §1, 5-2-2011]
A. 
An application for alternative landscaping schemes is justified only when one (1) or more of the following conditions apply:
1. 
The sites involve space limitations or unusually shaped parcels.
2. 
Topography, soil, vegetation, or other site conditions are such that full compliance is impossible or impractical.
3. 
Due to a change of use of an existing site, the required bufferyard is larger than can be provided.
4. 
Safety considerations require a change.
B. 
The application shall describe, in a letter to City Hall, which of the requirements set forth in the manual will be met with modifications, which project conditions justify using alternatives, and how the proposed measures equal or exceed normal compliance.
[Ord. No. 659 §1, 5-2-2011]
A. 
The following lists indicate planting which will meet the landscaping requirements of this Chapter. The lists are by no means comprehensive and are intended merely to suggest the types of flora which would be appropriate for screening and shading purposes. Plants were selected for inclusion on these lists according to four (4) principal criteria:
1. 
General suitability for the climate and soil conditions of this area;
2. 
Ease of maintenance;
3. 
Tolerance of City conditions;
4. 
Availability from area nurseries.
When selecting new plantings for a particular site, a developer should first consider the types of plants which are thriving on or near that site. However, if an introduced species has proven highly effective for screening or shading in this area, it too may be a proper selection.

A. 
The Board of Aldermen finds that:
1. 
Bufferyard requirements are designed to ameliorate nuisances between certain adjacent zoning districts or land uses. Bufferyards function to eliminate or minimize large changes in scale and potential nuisances such as dirt, litter, noise, glare of lights, unsightly buildings, parking areas, or signs. The bufferyard is a unit of yard together with the planting, fences, walls and other screening devices required.
2. 
Bufferyards can lesson the visual pollution that may otherwise occur within an urbanized area. Even minimal bufferyards can provide an impression of separation of spaces, and more extensive bufferyards can shield entirely one use from the visual assault of an adjacent use.
3. 
Bufferyards can establish a greater sense of privacy from visual or physical intrusion, the degree of privacy varying with the intensity of the bufferyard.
4. 
The provisions of this Section are necessary to safeguard the public health, safety and welfare.
[Ord. No. 659 §1, 5-2-2011]
A. 
Bufferyard requirements shall apply to all new development and expansion of existing development resulting in an increase of fifty percent (50%) or greater of the gross floor area. The developer shall submit a landscape plan showing compliance with this Section to the City of Strafford along with the building permit.
B. 
A bufferyard required by the Table of Bufferyard Requirements shall be provided by the proposed development when it is located in a zoning district listed in the left hand column of the table and the development abuts a zoning district listed across the top of the table.
C. 
Existing vegetation that otherwise satisfies the requirements of the Section may be retained to the extent practical and feasible. The developer may conduct an existing tree inventory, identifying the location, species, and diameter (at a point six (6) inches above grade) of all existing trees in the bufferyard, and complement the presence of such trees with appropriate shrubs and other vegetation to meet all the requirements of this Section.
