B. The landscape plan does not include the landscape layout requirements:
Tree Spacing ................................................................................. Not Specified
• No driveway conflicts; Prefer that the trunk of trees shall be 8-10 feet
minimum from the nearest driveway edge.
C. Interior Parking Lot Landscaping – The development does include interior parking lots.
1. At least 5% of the interior area of parking lots with more than 30 parking spaces
is devoted to landscape planting areas. The parking lot is measured at
approximatively 22,808 square feet and a planting bed measuring approximately
6,600 square feet separates the parking lot from the main entrance. The planting
area is approximately 34% of the interior of the parking lot area.
2. The planting area includes 7 shade trees satisfying the minimum required tree
planting requirements for interior parking lots.
D. Perimeter Parking Lot Landscaping – The development does not include perimeter
parking lots.
E. Screening – Screening is not required by City code.
Special Landscape Considerations:
A. 5th Street – The development is along 5th Street which has been completed with previous
phases of the Inwood development.
a. The applicant has marked the existing 5th street boulevard trees to remain which
meets the required 5th Street landscaping elements.
Findings:
1. Not all code required trees have been provided.
2. Landscape plans do not meet the minimum composition requirements.
a. Too many ornamental species have been proposed. Some of the ornamental species
should be exchanged for deciduous or evergreen species as they fit site conditions
and to meet the minimum composition requirements.
3. Landscape plans do not meet the landscape layout requirements.
a. The Boulevard Linden proposed by the entrance drive is located too close to the
driveway edge. See attached figure.
b. Only two (2) trees are proposed along Island Trail (measured at approximately 270
lineal feet of frontage) and does not fulfill street frontage requirements of one tree
every 50 feet. Provide additional trees along Island Trail street frontage to make the
streetscape cohesive with the rest of the Inwood development along Island Trail.
