This document is a Scope of Work for an urban forestry planting project by the City of Miami, funded through the Inflation Reduction Act Urban and Community Forestry Expansion Grant. The project involves purchasing and installing 644 trees across various size categories, including large (172 trees), medium (427 trees), small (35 trees), and palm (10 trees) varieties. The trees will be planted based on the Southwest Streetscape Master Plan, with specific requirements for tree quality, including Florida Grade #1 standards, single leader configuration, and precise caliper and height specifications. Tree species include Live Oak, Mahogany, Wild Tamarind, Green Buttonwood, Crape Myrtle, and various native Florida trees. The contract includes an 18-month maintenance period during which the contractor must water, fertilize, and replace any trees that do not survive, with monthly inspections and time-stamped photo documentation required.

The project has detailed specifications for planting, including soil composition (50% muck, 50% coarse silica sand), use of soil moist polymers, and Eucalyptus mulch. The contractor is responsible for protecting utilities, properly staking trees, and ensuring correct planting techniques. Invoicing requires proof of payment and lien releases from subcontractors. The total project value is not explicitly stated, but the comprehensive nature of the specifications suggests a significant urban forestry investment. Root deflectors may be installed at the discretion of the City Engineer or Project Manager, and there are provisions for potential tree relocation. The contractor bears the cost of replacements and must guarantee the trees' survival for the full 18-month period, with final acceptance contingent on the trees' health and growth.
