Tree and Vegetation Protection Plan: After consulting with the Grounds
Manager to identify the trees and vegetation to be protected within the general
construction area, the DP shall develop a comprehensive "Tree and Vegetation
Protection Plan" for inclusion in the project documents. This plan shall have
detailed drawings of each tree barricade and shall be included in the 50%, 100%,
and Bid set editions of the project documents. This plan shall be in accordance
with the latest edition of the pamphlet titled "Tree Protection During Construction"
by Duane Durgee and published by the Florida Department of Agriculture and
Consumer Services. (This pamphlet recognizes the damage that can occur to
trees through soil compaction and mechanical injury and prescribes measures
that can be taken to ensure protection.) A reprint of this pamphlet is included in
these Standards as Appendix A. An additional reference is the latest edition of
“Trees and Development, A Technical Guide to Preservation of Trees During
Land Development” by Nelda Matheny and James R. Clark, published by the
International Society of Arboriculture.
d. Trenching and Tunneling: Tunneling is encouraged if path is unavoidably near
large trees. All new underground utility lines including irrigation must be clearly
shown with existing tree canopies in the 50%, 100%, and Bid-set documents.
e. Inclusion of CONTRACTOR Requirements in Project Documents: The DP
shall include the below-listed “CONTRACTOR Requirements” (Items B.1-B.6) as
standard verbiage.
B. CONTRACTOR REQUIREMENTS:
1. TREE AND VEGETATION PROTECTION PLAN: Trees and other vegetation within
the general construction area (including construction parking areas) shall be
protected.
If the DP has not designed a tree protection plan, then the
CONTRACTOR shall develop and implement a plan to protect the trees and
vegetation in accordance with the latest edition of the pamphlet titled “Tree Protection
During Construction” by Duane Durgee and published by the Florida Department of
Agriculture & Consumer Services. Prior to commencing construction, the PROJECT
COORDINATOR, in consultation with the DP and the PCSB Grounds Manager shall
review and approve the CONTRACTOR-developed plan.
2. Tree barricade construction shall be completed before any other site preparation or
vehicle entry, other than perimeter fence construction. After completion of tree
barricade construction and prior to any additional site preparation the DP and the
PCSB Grounds Manager shall inspect the tree barricades for compliance with the
approved plan.
3. Areas within tree barricades are to be mulched with four inches of hardwood tree
chips after barricade construction and kept free of any foreign material including
trash, construction debris, building materials or vehicles. Any normal maintenance of
shrubs or groundcovers within the construction area is the responsibility of the
CONTRACTOR. Any tree care work within the construction area is the responsibility
of the CONTRACTOR. Under no circumstances shall any wires or ropes be attached
to trees for electrical service or any other reason.
4. REPLACEMENT OF TREES AND VEGETATION: Any vegetation, including trees
and shrubs, damaged or destroyed shall be replaced or mitigated by the Constructor

with like species or another species approved by the PCSB Grounds Manager. In the
case of trees, mitigation shall occur on site whenever possible, elsewhere on campus
if necessary due to space considerations. Mitigation trees shall be Florida Nursery
Grade Number One or better and shall be a minimum of eight feet in height. The
CONTRACTOR shall be held liable for the difference in value between the
replacement tree and the original tree (value set in accordance with the International
Society of Arboriculture’s latest edition of “Guide for Plant Appraisal”, “Replacement
Cost Method,” edited by the Council of Tree and Landscape Appraisers, published by
the International Society of Arboriculture). That difference shall be subtracted from
the contract amount to be paid the CONTRACTOR.
5. WARRANTY POLICY:
a. All protected/existing landscaping within the work area and any new landscaping
alive and in healthy condition shall be warranted one (1) year from date of
replacement, corresponding with the length of the Contract for Landscape
Maintenance as defined in the DP’s Specifications
b. The CONTRACTOR shall be responsible for notification, in writing, of the owner
30 days prior to the end of the warranty period. The owner has the option to do
an end of warranty inspection at that time. Failure of the CONTRACTOR to
notify owner of end of warranty shall cause the warranty period to extend, until
such time as the CONTRACTOR gives the owner 30 days end of warranty
notice.
6. MAINTENANCE: The CONTRACTOR shall fully maintain all landscaping until the
substantial completion punch list is completed and a final completion inspection is
performed with no unfinished items.
3.02
LAWNS AND GRASSES:
A. ESTABLISHING NEW GRASSED AREAS: Normal procedure shall be to use sodding for
new-grassed areas. Seeding should only be considered in large areas with low public
visibility, and shall have approval from PCSB Grounds Manager; make special provision
for control of soil erosion. Sod shall be sand grown; mud-grown sod is not acceptable.
B. RESODDING/RESEEDING: Any area of vegetation that is damaged during construction
shall be restored to its original state within 72 hours of the completion of the
associated construction work. Grassed areas shall be resod. Under no circumstances
is sod to be placed against tree trunks. Mulch rings or beds are to be maintained or built if
necessary around trees. Special care shall be taken before and after the restoration to
ensure the area is not subject to erosion. Reseeding shall only be allowed in special
cases with each individual case approved by the Owner, in consultation with the PCSB
Grounds Manager. CONTRACTOR shall be responsible for watering all replacement
vegetation until project area is turned over to PCSB Grounds Manager
C. TOPSOIL AND GRADING: Topsoil shall be suitable for ornamental plant growth and free
from hard clods, stiff clay, hardpan, gravel, subsoil, brush, large roots, refuse or other
material and of reasonably uniform quality. Finish Grading of all lawn and planting area
shall be to a smooth, even, and uniform plane with no abrupt change of surface. The soil
