Design landscaped areas in accordance with Presidential Executive Order 13148 of April 2000, with a goal to reduce fertilizers, pesticides, and water use.  The intent is to achieve a base-wide ratio of 20 percent maximum non-native plants and 80 percent minimum locally or regionally native plants.   Do not use plants deemed invasive by the project state or region's Exotic Pest Plant Council, State Department of Agriculture or local chapter of the American Society of Landscape Architects as a threat to ecosystems or agriculture.  Select only plant species which require little or no supplemental irrigation after the initial establishment period.  Only nursery-grown plants are acceptable.  Cover non-paved site areas disturbed by construction operations with plant material or inorganic mulch.  Stabilized soil, decomposed granite, and organic mulch are not acceptable as ground covers.  Provide landscape architectural work in accordance with UFC 3-201-02, Landscape Architecture.  For projects with planting or irrigation areas, utilize the design services of a Landscape Architect licensed in the state of the project.  The Landscape Architect of Record must visit the site at least once prior to design, twice during construction, and quarterly during the Establishment Period, including the Establishment Period start and completion.  The Landscape Architect of Record must attend the kickoff partnering meeting and CDWs.  Courtyards and plazas are to be designed by the Landscape Architect.  For the CDW, provide a Site Analysis Plan to demonstrate the design thought process.  It is the Contractor's responsibility to coordinate between disciplines including architecture, civil engineering, electrical engineering, mechanical engineering, fire protection, and landscape architecture.  Coordinate location of utilities, structures, and equipment. For projects in dry climates (arid and semi-arid), eliminate or minimize the use of turf, except when needed for active or passive recreation.

The Landscape Architect-of-Record is required to submit 5 sample boards of landscape materials.  Sample boards to include but not limited to colors, finishes, textures of hardscape paving, walls, signs, monument piers, inorganic mulches, organic mulches, and other site improvements.  Include cut sheets of proposed plant material.

Preserve existing trees to the greatest extent possible.  Identify preserved trees on the plans with tree species, caliper and dripline.  Tag trees to be saved with plastic or vinyl tape tied to the tree caliper.  Protect existing trees by fencing planting areas to remain from compaction and other damage with a barrier of metal poles a maximum 8 feet (2.4 meter) on center with plastic netting to a minimum of 10 feet (3.0 meter) radius from outside of the tree's trunk.  Where tree drip lines are greater than 10 feet (3.0 meter) from the tree's trunk, locate barrier fencing at the drip line of the tree.  Install signs on each Tree Protection Zone fence indicating that the barrier is not allowed to be taken down or moved without the participation of a Certified Arborist.  Ensure that the details and specifications clearly state that none of the following activities occur within the tree protection barricade: driving, parking, storing materials, dumping waste, concrete washout, adding fill soil, trenching, removing soil, grubbing, or other disturbance to the tree or the associated roots.  Do not allow debris from tree or stump removal operations to fall on or otherwise damage plants that are not scheduled for removal.  Do not remove plastic tape and barrier fencing until planting operations are ready to begin and or instructed by the Contracting Officer.  Replace existing trees to remain or to be transplanted that are unhealthy, that die, or have 20 percent or more of their crowns that die during the establishment period with healthy plants of the same species or variety during the appropriate planting season.  During the landscape establishment period, replace trees, turf, shrubs, and ground cover that are damaged or destroyed during construction operations by the Contractor at no additional cost to the Government.  At the direction of the Contracting Officer, remove the existing tree and stump and replace it with trees of the same genus and species equal to the total caliper of the existing tree.  Provide replacement trees that are 4 inch (100 mm) minimum caliper. Replace shrubs with 5 gallon (18.9 liter) size container, ground cover with flat containers planted at 8 inches (200 mm) on center, and turf with sod, all of the same genus and species.

G205005 1.2 UTILITIES

Do not place trees within 10 feet (3 meter) of above or below-grade utility line or structure.  Within roadway sightlines, height of mature shrubs is limited to 3 feet (1 m) and trees must be limbed up a minimum of 6 feet (2 m) so their mature growth does not obstruct views from vehicle intersections or points of vehicle ingress or egress.  Coordinate utilities between the Landscape Architect and appropriate disciplines.

G205005 1.3 RECYCLING

Green waste:  Contact the Public Works Department for potential green waste collection and hauling by the Government.  Separate green waste not collected by the Government from construction debris and deliver to the base's or local landfill's green waste recycling area.  Quantify and report diverted waste to the Contracting Officer.

G205005 1.4 PLANTING

For dry climates (arid and semi-arid) only: Plant a minimum of 40 percent of the landscaped areas with shrubs and groundcover so that at 50 percent plant maturity, they form mass plantings.  Utilize a minimum ratio of 60 percent 5 gallon (18.9 liter) shrubs or groundcover and 40 percent 1 gallon (3.79 liter) shrubs or groundcover.  The remaining 60 percent of the landscape area may be inorganic mulch, planted or a combination thereof.  For inorganic mulch, provide 3 inch (76 mm) depth of 3/4-inch (19 mm) and smaller rock, and for larger than 3/4-inch (19 mm) size, assure complete ground surface coverage.  Provide plant material calculation summary matrix on planting plan.

For other climate zones:  Plant the majority of shrubs at major entrances to buildings and at other important planting zones that are specific to each site.  The overall design intent is to plant mostly trees and turf, with shrubs and ground covers used sparingly, to reduce maintenance costs while still providing for functional planting requirements (e.g., soil stabilization, energy conservation, force protection, and aesthetics).  Provide a minimum size 3 gallon (11.4 liter) container for shrubs and 1 gallon (3.79 liter) container for ground covers.
