NOTES:
| |
|
*
|
Building height is measured as defined in § 410-132.
|
|
**
|
Only applies to the existing number of units. Any additional
units shall meet the requirement for a new lot.
|
|
***
|
Maximum front yard setbacks apply within the Commercial Downtown Zone, as prescribed in § 410-44.2.
|
|
****
|
Minimum side yard setback requirement when directly abutting
residential zoning districts only; minimum side yard setback of 10
feet applies when abutting commercial or industrial zoning districts
or properties with established commercial or industrial use. Minimum
side yard setback of zero feet applies for contiguous parcels under
the same ownership.
|
A.
In no instance shall the distance between an existing primary building
on a separate lot in the same zoning district as the subject lot and
a newly constructed building on the subject lot be less than twice
the side yard setback for the subject lot.
[Added 9-21-2006 by Ch. No. 2825]
Newly created buildable lots must conform to
the following requirements for lot width: No part of the lot that
lies between the street line and the minimum required rear yard setback
for the district in which the lot is located shall be narrower in
width than the lot's frontage.
[Added 10-6-2011 by Ch. No. 2981]
The maximum front yard setback within the CD District is 40
feet. Design of the front yard setback shall preclude parking spaces
and travel lanes and shall be dedicated exclusively for pedestrian
and/or bicycle activity.
