MEMO TO: PLANNING AND ZONING COMMISSION
FROM: SCOTT WILLIAMS, DEVELOPMENT SERVICES DIRECTOR
MEETING DATE: DECEMBER 19, 2017
SUBJECT: ZONING ORDINANCE AMENDMENTS AM17-04-AMENDMENTS
TO SECTION 52, TREE PRESERVATION AND SECTION 53,
LANDSCAPING REGULATIONS
RECOMMENDATION:
Staff recommends the Planning and Zoning Commission consider the proposed
amendments to Section 52, Tree Preservation and Section 53, Landscaping Regulations
relative to approved trees meeting minimum landscaping requirements, and take any
necessary action.
BACKGROUND:
The approved tree list adopted by the City of Grapevine currently allows ornamental pear
trees ("Callery Pear") as acceptable trees to meet landscaping requirements. Varieties of
ornamental pear trees include "Rancho", "Aristocrat", "Capital', and "Bradford".
Unfortunately, these trees have proven to be short lived, disease prone, and brittle. These
trees often receive the greatest damage during wind and ice storms, and there are
examples throughout the City of these trees in horribly deformed and/or dying condition.
Another problematic tree is the Bald Cypress. These trees not only require tremendous
amounts of water, but also have rampant and destructive root systems, making them a
very poor choice as a general landscaping tree.
Staff recommends removing these trees from the Required Tree List For Required
Landscaping as shown in the attachment. Staff has consulted the Parks Director,who also
recommends this amendment.
