Background Discussion

• Revise Section 714.8.7, Required Replacement Caliper Minimums, by changing the minimum caliper replacement tree to allow replacement tree sizes at 3”/4”/4” instead of 3”/5”/7”. 

• Revise Section 715.3.4, Residential Street Trees, to allow:
a. one (1) tree per lot per frontage when proposed lots have less than 100’ of frontage, and
b. lots less than 60 feet of frontage to be planted with smaller maturing canopy trees or understory trees.

• The above revisions have been made on a case by case basis with Planned Development applications through the Specific Approval process.  Staff has been recommending the above revisions based on the following reasons:

? Section 714.8.7. Tree Replacement Alternatives.
The intent of this change is to reduce the size of replacement trees to match inventories that tree nurseries typically produce. The majority of plant nurseries plan to bring to market canopy trees at the average size of 3 inch caliper, with most trees sold in the 2 inch to 4 inch caliper range. This is the size range when the tree is developed for a central leader with evenly spaced branching emitting from this dominant leader. The “Plant List” publication has nurseries listing where at least 2/3 of the live oak nursery listings are for trees less than 5 inch caliper.

Additionally, the 3 and 4 inch caliper sized tree establishes in the landscape in a much shorter period of time than trees ranging in size from 5 inch to 7 inch caliper. It takes about three and one-half months per caliper inch to establish a tree in the landscape. This results in an established 3 inch tree in less than one year versus two years for a seven inch tree. Smaller trees can begin to catch up in growth to the larger trees.

? Section 715.3.4. Residential Street Trees.
A minimum of one tree is recommended to be installed on lots less than one hundred feet in width in order to allow for adequate space for the street tree to accommodate public and private sidewalks, driveways, water lines, electrical transformers, gas lines, street lights and side yard drainage and utilities easements.  Healthy tree canopies will flourish and reduce impacts to the built infrastructure on residential lots. Adequate tree spacing reduces competition with neighboring tree canopies, resulting in fully developed canopies. The canopy that results with the recommended change to spacing is seen as sustainable, resulting in shading of sidewalks and at least partial shading of streets.

For proposed lots less than sixty feet in width, an intermediate sized tree may be used in order to fit within pavement and utilities and be sustainable. This is to tie into The Florida Friendly Landscaping™ principle of Right Plant, Right Place. Section 714.8.5 has language that replacement residential street trees are dependent on lot size. The recommended amendment specifies the size lot which may be planted with smaller, maturing trees.

• Staff recommends approval of the amendments as proposed.
