(3) Parking Areas
(a) Perimeter Parking Lot Landscaping
Landscaping shall be provided between parking areas and all public streets.
The minimum landscaping required for this purpose shall be based on the
measured linear footage of parking including vehicular circulation routes that
extends along the length of the property line (excluding driveways) adjacent to
the public or private right-of-way. To determine the minimum quantity of
landscaping the following guidelines apply:
(i) One large or medium tree species per fifty (50) linear feet (75 % of the
these trees are to be of a large tree species); and
(ii) One small tree species per twenty (20) linear feet; and
(iii) One five (5) gallon container size large shrub per four (4) linear feet.
(iv) Trees provided in this section may be credited toward the street yard
tree requirement.
(v) The specific location where trees and shrubs are planted along the
perimeter shall be determined by the Landscape Architect preparing the
site plan. The spacing requirements between trees in the City of Round
Rock Tree Technical Manual: Standards and Specifications shall not
prohibit the grouping of small tree species twelve feet (12') apart;
medium tree species twenty feet (20') apart; and large tree species
thirty feet (30') apart for the purpose of meeting the requirements of
this section.
(vi) An eight -foot wide linear landscaped area unencumbered by easements
shall be provided between all parking areas and public streets to meet
the requirements of this section. However, this area may be reduced if
the site is determined to be entitled to the Alternative Compliance
provisions of §11.501(5).
(vii) If the planting of large or medium trees can not be achieved due to the
presence of an overhead electric line, then such trees may be placed in
landscape islands within the first row of parking adjacent to the public
street. Such islands shall have a minimum width of ten feet (10') from
back of curb to back of curb.
(b) Interior Parking Lot Landscaping
(i)
A landscaped end island with a minimum width of ten (10) feet from
back of curb to back of curb shall be provided at the terminus of each
parking bay. All end islands shall be landscaped with a minimum of one
large tree. The spacing requirements between trees in the City of
Round Rock Tree Technical Manual: Standards and Specifications shall
not apply to end island trees.
(ii) A median island with a minimum width of ten (10) feet, from back of
curb to back of curb, shall be sited between every six (6) single parking
bays and along primary internal and external access drives. Median
intervals may be expanded in order to preserve existing trees, provided
an alternative median location has been approved by the Zoning
Administrator.
(iii) Landscaping within a median shall consist of medium trees. Spacing
between trees shall not exceed forty (40) feet on center.

Item Summary:
The City of Round Rock has two sets of provisions that regulate landscaping: The Landscape Section of the Zoning
Ordinance and the Tree Technical Manual of the Tree Protection Ordinance. These regulations are independent of
each other and strive to implement different goals. In general, the intent of the Landscape Section is to encourage a
creative, aesthetically pleasing design; increase development quality; and mitigate the impacts of development on
neighboring properties. In contrast, the Tree Technical Manual aims to maximize long term tree growth. Since these
two sets of provisions were adopted years apart from each other, some unintended conflicts exist. The City received
several comments in the development survey citing the need to resolve these conflicts. The purpose of this
amendment is to reconcile the competing provisions of the Landscape Section. As a result, obtaining an approval for
a landscape plan should become a quicker and easier process.
Strategic Plan Relevance:
Identified as an objective in Goal 4.
