As such, they shall have, in addition to trees, landscaping or a combination of landscaping with walls or fences to provide screening. 5. Walls and Fences must be coordinated with the building architecture of the project. 6. Shrubs used for screening shall be 18" tall, or taller, at installation, to be maintained at 36" tall at maturity. 7. Ground Cover and/or Sod shall make up the balance of the buffer landscape, as required for ease of maintenance and erosion control. PART 3.01 3 ‒ EXECUTION PRE-CONSTRUCTION A. REQUIREMENTS: 1. In the SITE ANALYSIS PHASE before site planning begins, the tree survey, evaluation, and tree preservation determination have to happen in the earliest site analysis phases before site planning begins then the following items can happen in a timely manner: a. Surveying: The following items shall be written into the Surveyor’s scope of work: 1). Surveying activities shall avoid removal of landscaping, trees and other vegetative growth in order to establish site lines. When necessary, any such vegetative removal shall be coordinated with the PROJECT COORDINATOR and the PCSB Grounds Manager. b. Consultation with the PCSB Grounds Manager and DP: During the design process, the DP shall consult with PCSB Grounds Manager to identify trees and other vegetation within the general construction area (including constructionparking areas) that shall require protection during construction. This shall also seek to identify any listed endangered or threatened flora/fauna on the site. When encountering any listed species follow procedures and seek consultation with the appropriate agencies as identified in the Florida Game and Fresh Water Fish Commission’s Wildlife Methodology Guidelines.

DIVISION 2 Issue Date: 6.09.2014 Revision Date: SECTION 02900 — LANDSCAPING c. 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 PCSB 02900 – 6 of 8 DIVISION 2 Ӏ SECTION 02900 POLK COUNTY SCHOOL BOARD DESIGN AND CONSTRUCTION STANDARDS These Standards are for guidance only. DIVISION 2 Issue Date: 6.09.2014 Revision Date: SECTION 02900 — LANDSCAPING 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 PCSB 02900 – 7 of 8 DIVISION 2 Ӏ SECTION 02900 POLK COUNTY SCHOOL BOARD DESIGN AND CONSTRUCTION STANDARDS These Standards are for guidance only. DIVISION 2 Issue Date: 6.09.2014 Revision Date: SECTION 02900 — LANDSCAPING surface for re-sodding shall be loosened to a minimum depth of two inches except near trees where roots are at the surface. 1. For Athletic Fields only top soil shall consist of a 90/10 ratio, 90% sand and 10% organic fill. END OF SECTION PCSB 02900 – 8 of 8 DIVISION 2 Ӏ SECTION 02900
