uses and PD projects. Standard single-family development is exempt. Chapter 926 generally addresses landscaping issues as follows: •Timing No C.O. is to be issued for a project until landscaping requirements are satisfied. •Quality/Quantity 1. Plant materials are to conform to the Standards for Florida No. 1 or better. 2. At least 50% of the plant material is to be drought tolerant. 3. Specie diversity is required, and certain nuisance species are prohibited. 4. Minimum at -planting sizes are specified for trees (canopy), understory trees, shrubs, and vines. Credits are given on a graduated scale (by size) for preserving existing trees. 5. Standards for buffer types (A, B, C, D) and opaque features are given: requirements vary by buffer type and buffer strip depth. Note: the various zoning district regulations (Chapter 911) and specific land use criteria (Chapter 971) dictate under what circumstances and where various buffer types and opaque features are required to be installed. 6. Irrigation requirements and standards are specified, •Location 1. Landscaping strips with various material quantities are required to be located: a. Between parking areas and abutting road right-of-way b. Between parking areas and abutting properties C. Interior to parking areas d. Within non -vehicular open space areas 2. For traffic safety at intersections, sight distance requirements are specified. •Maintenance 1. Project owners are required to maintain project landscaping in accordance with the project's approved landscape/site plan. .. The pending ordinance (see attachment #2) reviewed by the Board of County Commissioners on July 23, 1997 is now being applied to new projects. The pending ordinance does not overhaul Chapter 926, but generally clarifies existing requirements and strengthens certain landscaping installation and maintenance standards. The pending ordinance makes various modifications to the Chapter 926 requirements, as follows: 1. Tree Size Requirements Allows palms to count as canopy trees only if clustered (e.g. 3 sabal palms = 1 canopy tree), or is a type of palm with a large canopy (e.g. canary island date palm). Reason: Combined "volume" of palm heads needed to equate to mature crown of canopy tree (15' diameter "sphere"). Codifies existing policy and matches SR 60 standard. Codifies the minimum tree sizes required in the Wabasso and SR 60 corridor plans. Reason: Brings LDRs into line with some of the adopted corridor plan requirements: applies within designated Wabasso and SR 60 corridors only. 3 September 8, 1997 b�JJ1K 2 PAGE 4812
