Facilities Management
2014
1. General Requirements
Before you begin, these base requirements must be met to ensure safety and success in the garden.
1.1 Locate Underground Utilities
All underground utilities must be located within the proposed garden area prior to commencing any
work. You can call Dig Safe (811) to have underground utilities located.
1.2 Locate Water
Make sure that there is an external water source near your proposed garden site. Ask your custodian
about where there is water and how to access it.
1.3 ADA Compatibility
Designs should consider ADA compatibility. Applicable standards are referenced throughout this
document. The full ADA standards can be found at:
http://www.ada.gov/regs2010/2010ADAStandards/2010ADAstandards.htm#pgfId-1006229.
2. Design Requirements
Due to accessibility and maintenance, Facilities Management requires that garden beds built on BPS
property comply with the following design requirements:

2.1 Raised Planter Boxes
The following garden bed types have been approved; any
other bed designs must be specified in the garden
application, to be approved by Facilities Management.

This prefabricated kit can be easily constructed by
volunteers. (Figure 1) http://gardenraisedbeds.com/
 4”x4” (or 6”x6”) garden beds
Figure 1: Mortise and Tenon Garden bed
This sturdy design requires some woodworking skills. It also has an
optional root viewing window. (Figure 2)
http://schoolyards.org/pdf/planter_w_window_specs.pdf
Bed specifications
 Garden beds should use rot resistant or heat treated wood,
but not chemically pressure treated wood.
 Landscape fabric should be used at the base of the beds.
 Beds should have a minimum of 8 inches of clean soil. Root
vegetables and large fruiting plants require at least 16
inches of clean soil.

o Do NOT reuse soil from the site.
o Do not plant into pure compost.
o Make sure soil distributor tests for lead.
2.2 ADA (Americans with Disabilities Act) for Raised Planter Boxes
Work surface height of raised planter boxes
Raised beds with a built-in work surface (i.e. a wide top edge for writing or sitting) should comply with
ADA standards.
 Elementary school – 26 to 30-inches high at the top of the box. (ADA 902.4)
 Middle school/high school – 28 to 34-inches high at the top of the box. (ADA 902.3)
Width of planter boxes
In consideration of reach into garden beds, maximum bed widths should be 48-inches. (ADA 308.3)
Space between planter boxes
In accordance with ADA standards, spaces between planter boxes are considered pathways and must
meet pathway clearance standards. (Section 2.5)

damage, the following easements must be observed.

 Gardens must be 4-ft from underground utilities.
 Overhead lines must be at least 12-ft above gardens.
 Trees and shrubs must be 8-ft from underground utilities, and 16-ft from overhead lines.
2.4 Fences & Gates
Fences are strongly encouraged around large gardens to help
manage students and to discourage undesired or damaging
trespassing. The following fence types have been approved;
any other fence type must be specified in the garden
application, to be approved by Facilities Management.
 Black permafused chain link fence & gates, 4-ft high
Figure 3: Black Permafused Chain Link Fence

 Welded wire mesh fence, 4.5-ft high
http://www.omegafence.com/en/omega.php (Figure 4)
 Permanent tree protection fence
Gate design
 At least one 32” minimum clearance width ADA
pedestrian gate is required. (ADA 404.2)
 Locks should be Sesamee KCR0436 (standardized
Figure 4: Welded Wire Mesh Fence
combination for BPS gardens is 2-0-2-0).

2.5 Pathways
Universal access should be considered in planning all pathways.
Pathway clearance
 The minimum clear path of travel must be 36-inches wide around all planter boxes. (ADA 403.5)

Acceptable pathway materials
All listed pathway materials are acceptable; any other pathway materials must be specified in the
garden application to be approved by Facilities Management.
Smoothest & Most Stable
Roughest & Least Stable
Asphalt
Chip seal
Stone dust*
Pavers
Pavers in stone dust
Engineered wood fiber
Deck
Pavers in mulch
*Stone dust must be compacted and 3-4 inches thick to be compliant.
Stone dust and engineered wood fiber are common pathway materials between garden beds.
3. Component Requirements
3.1 Composting Bin Options
The City of Boston has several resources for compost bins. The following compost bin styles have been
approved; any other designs must be specified in the garden application to be approved by Facilities
Management.
 Plastic compost bins
These bins are very simple to put together, are affordable, and generally work well.
http://www.cityofboston.gov/publicworks/wastereduction/composting.asp
 Welded wire compost bins
These can work well for yard debris, but are not suitable for food scraps because of pests. They allow
students to see the layers of decomposition for a great educational experience, and are easy to build.
http://www.cityofboston.gov/images_documents/welded%20wire%20bin_tcm3-39939.pdf
 Commercially purchased compost tumbler
These are not sold through the city of Boston, but can be very effective, and can help keep out pests.
http://www.woodlanddirect.com/Outdoor/Compost-Tumblers/Tumbling-Composter
 Vermi-compost
This system of using worms for composting is very fast and effective. The students might also enjoy
watching the worms work. It can be used to teach responsibility since the worms will need to be
"fed" periodically with new scraps. The city has one and two bin designs, and there are also
commercially available worm compost bins.

3.2 Tool Sheds
Experience has shown that tool sheds are less likely to be broken into if the contents are visible (most
people won’t steal dirty gardening implements). The following tool sheds have been approved; all other
tool shed designs must be specified in the garden application to be approved by Facilities Management.
 Securall brand LP/oxygen storage cabinets
These storage units have been used as secure, yet visible tool storage in several gardens.
http://www.interstateproducts.com/securall/cabinets/lp_&_oxygen_gas_cylinder_storage.htm
 Commercially purchased tool sheds
Commercial tool shed are acceptable, but risk vandalism or damage.
Tool shed specifications
 Skylights or battery operated lights are the only acceptable means to light the shed. Electrical
wiring is NOT permitted.
 Locks should be Sesamee KCR0436 (standardized combination for BPS gardens is 2-0-2-0).

3.3 Miscellaneous Structures
Custom-built enclosures, trellises, greenhouses, shade structures, arbors, etc. must be specified in the
garden application to be approved by Facilities Management. These structures must be constructed with
durable materials and finished to minimize future maintenance.
4. Plant Requirements
4.1 Plants
Plant lists and planting plans must be submitted with the Garden Application and approved by Facilities
Management. The following criteria are guidelines for developing garden planting plans.
Fruits and vegetables
Perennial plant stocks should be rated hardiness zone 6 or lower. One should consult The Old Farmer’s
Almanac and Green City Growers on best planting times, and for first and last frost:

Fruit trees
Fruit trees are discouraged in favor of shrubs and contained vines for reasons of maintenance. Any fruit
tree planting must first be approved by BPS Facilities Management.
5. Support from BPS
Facilities Management would like to help support gardens in our schools to the best of our ability. For

Contact John McIntosh one week in advance to schedule a yard waste pick up. During peak times, please
contact your custodian to coordinate leaf pickups.
5.2 Garden Materials
Before requesting the following resources please contact your custodian to determine what resources
you already have available at your school.
All schools should have…
All Boston Public Schools should have the following:
