Landscape and Buffer Planting and Maintenance Specifications

Landscape and Buffer Planting and Maintenance Specifications Jefferson Parish, Louisiana Administered by the Jefferson Parish Planning Department Effective August 19, 2017 1. Purpose The Landscape and Buffer Planting and Maintenance Specifications provide standards for the planting and maintenance of required landscaping with the intent to ensure the long-term vitality of landscaping on sites for which site plan review is required by the applicable development regulations. Long-term vitality of plant materials also will reduce replacement costs for property owners. 2. Tree Class There are three (3) classes of trees: A. Class A Trees (1) Overstory Trees. Diameter-at-breast-height (DBH) in excess of twenty-five (25) inches and height in excess of 50 feet at maturity. (2) Mid-Story/Mid-Canopy Trees. Typical diameter-at-breast-height (DBH) of ten (10) to twenty-five (25) inches and height of thirty (30) to fifty (50) feet at maturity. B. Class B Trees Typical diameter-at-breast-height (DBH) of less than or equal to fifteen (15) inches and height of less than or equal to thirty (30) feet at maturity. C. Class C Trees 3.

Seasonal Installation Because some landscaping elements may require specific seasonal planting, a property owner or the applicant may petition for deferred planting as allowed by the Planning Director. Deferred planting may be allowed only to accommodate construction during the months of June through August when weather conditions would create stress on plant materials or hardship with installation. If granted, deferred planting would allow the issuance of a certificate of completeness or occupancy, conditioned on the timely installation of required landscaping at the earliest appropriate time. 6. Irrigation A. Maintenance of installed irrigation systems Irrigation systems must be constantly maintained to eliminate waste of water due to seasonal change, loss of heads, broken pipes, or misadjusted nozzles. B. Manual watering If no permanent, in-ground irrigation is installed, the property owner is responsible for the provision of adequate water to required plant materials.
