SOW_Appendix_3_Landscape_and_Design_Procedures.pdf

General Landscape Theme

Develop the Florida Coastal look with regional plant materials in curvilinear layouts. Include landscaping with all new facilities and use it to enhance and unify existing non-conforming facilities. Sustainability and low maintenance are the dominant goals for a properly designed landscape. In order to achieve these goals it is critical to select the right plant for the right location.

This can be achieved by understanding the level of maintenance a particular site will receive and by visiting the site to analyze its critical functional and aesthetic issues. Once this is accomplished, the designer can create a landscape plan that will reinforce and enhance the semi-tropical character of the area. Creating continuity and reducing the negative visual impact of unsightly features are some of the primary goals of the designer.

Maintenance and Design Procedures

• Conduct a site analysis to record the site’s existing conditions. There may be established plant material that can be saved.

• Determine the site’s ground category located on the Grounds Categories Map on page 13.

• Use only approved planting material as specifi ed on the Landscape Material List located on page

14. Note the plant characteristics and ground categories given on this list indicate the ground category that a plant can be used in. Ground categories are based on the amount of maintenance an area will receive. It is critical that the designer specify the right plant material based on the amount of maintenance that a site will receive.

• Follow the Landscape and Irrigation Specifi cations located on page 27.

•Reduce maintenance by using proper plant materials in confi gurations that reduce or eliminate pruning.

Landscape Theme and Design Procedures

• Review the typical planting examples provided for different grounds categories located on pages 6-11.

• Install an irrigation system for new plant material.

When irrigation cannot be installed, provide a hand-watering schedule to establish planting growth and provide a soil polymer to retain water at the plants root system.

• All rock beds shall be treated with a pre-emergent herbicide and then top-dressed with 10 ml of weed fabric.

• All plant beds and tree rings shall be treated with a pre-emergent herbicide and then top-dressed with 3” cypress mulch. All new trees shall have a tree ring with a minimum of 24” radius. All new trees and palms shall be staked. All existing trees to remain shall have a 6’ radius mulch ring at a depth of 3”.

• Provide an 18” wide mulch area between a building and its foundation planting.

Edging

• Separate and defi ne all planting areas with sod cut edging.

• Provide polyethylene edging at all rock beds.

Landscape Screens

• Where possible use landscaping instead of walls for screening.

• Use large shrubs and trees that are appropriate for each site.

• Use shrubs, vines and trellis structures to screen mechanical equipment.

Open spaces

• Use a minimal plant palette, which provides pedestrians with excellent sight visibility and ties adjacent landscapes together.

• Use plant material to focus and direct pedestrian and vehicular traffi c.

• Use turf for all recreation areas, parade grounds, and open fi elds.

• Create sustainable natural areas using native plant material.

• Use plant material to control erosion problems where steep slopes may occur.

Streetscaping

• Landscaping along streets plays many roles. Landscaping establishes the hierarchy of the roadway by creating a uniform theme. It should focus and direct pedestrian and vehicular traffi c, and enhance security for sensitive facilities.

General Landscape Standards

Roadways (Route of Excellence and Improved/ Semi-improved areas)

• For primary roadways, plant evergreen street trees equally spaced to coordinate with light standards (see improved areas example on page 6). New trees should match existing species and specifi cations to create a uniform appearance.

• Use palms on high-profi le primary streets equally spaced to coordinate with light standards. New palms should match existing species and specifi cations to create a uniform appearance.

• Reduce the density of plantings in the industrial and fl ightline areas.

Parking Areas (Route of Excellence and Improved/ Semi-improved areas)

• Reduce negative visual impact of large parking areas with landscape buffers and parking islands. Evergreen shade trees should be used in parking islands when irrigation is provided. Limestone boulders and red cedar barkstone should be used in small parking islands where irrigation may not be provided.

• Use shrubs in groupings around the perimeter of parking areas to soften and buffer views from the street or facility.

Use evergreen trees or palm clusters to provide shade to the parking area.

• Avoid the use of large trees and shrubs where sight visibility and safety is a concern.

Recreational Trails

• Incorporate formal plantings at high visibility areas along the trail system.

• Use informal groupings of trees, shrubs, and fl owers at rest stops, play areas and intersections.

Facility Landscaping

• The goals of facility landscaping are to provide a soft transition from the horizontal ground plane to the vertical building plane, to highlight building entries and features.

Hide unattractive building features such as utility risers or service areas.

Community (Route of Excellence and Improved areas)

• Use landscaping elements that compliment building architectural features and proportions.

• Limit the use of palms to entries and high-visibility areas by framing desired views.

• Apply three-tiered planting schemes of ground cover, shrubs, and trees using a variety of species in lush combinations to provide seasonal color at building entries and other areas of focus.

• Provide security buffer when necessary (see pages 10-11).

Industrial and Flightline (Improved and Semi-improved areas)

• Minimize the use of deciduous trees and shrubs to prevent leaf buildup along the apron and runway.

• Reduce the quantity of landscaping by grouping landscape elements at entries and high-visibility areas.

• Provide security buffer when necessary (see pages 10-11).

General Offi cers Quarters

• Use landscaping elements that compliment building architectural features and proportions.

• Limit the use of palms to entries and high-visibility areas by framing desired views.

• Apply three-tiered planting schemes of ground cover, shrubs, and trees using a variety of species in lush combinations to provide seasonal color at building entries and other areas of focus.

• Provide security buffer when necessary (see pages 10-11).

Military Family Housing

• Use palms or accent trees on the corners of the front facade.

• Use evergreen shade trees to line the roadways.

• Limit the use of shrubs and ground cover due to limited irrigation.

• Provide irrigation bubblers at trees or a hand-watering schedule to establish growth.

• Lawn areas must be bahia sod due to limited irrigation.

• Provide accent plantings at neighborhood entries and signs

Landscape Design, Route of Excellence Road right of way

• The primary goal is to create scenic roadways and facilities by establishing a landscape theme.

• Use palms equally spaced to coordinate with light standards.

New palms must match existing species and specifi cations to create a uniform appearance.

• Use St. Augustine or Bermuda grass in right of way, match existing conditions.

• Provide excellent sight visibility for pedestrians and vehicular traffi c.

Facility Landscape

• Create a three-tiered planting scheme of trees, shrubs and ground covers.

• Develop the Florida Coastal look using the approved plant list (see Route of Excellence Example).

• Plant evergreen trees between the facility and sidewalk to provide shade, coordinate spacing with lighting standards and existing site conditions.

Route of Excellence Example

Landscape Design, Road Medians

Landscape Theme

• Create a sustainable low maintenance landscape with visual continuity (see median example).

• Develop the Florida Coastal look with regional plant materials in a curvilinear layout.

Landscape Material

• Use red cedar barkstone and limestone boulders along the perimeter of the median.

• Create a curvilinear planting bed in the middle of the median.
