STAFr REPORT
AGENDA ITEIVI: Request for a Waiver from the Land Development Regulations to exceed the
50% Impervious Surface Area limit to allow for an addition to a residence
within the Selva Linkside PUD for a lot located at 1629 Linkside Drive, North.
' SUBIVIITTED BY: Sonya Doerr, AICP, Community Development Director
.. Rick Carper, P.E., Public Works Director
DATE: July 14, 2005
BACKGROUND: The Selva Linkside PUD was approved in 1987, and developed prior to the
City's adoption of the 50% Impervious Surface Area (ISA) limit in November of 2001. Subject
property was originally built to ~58%ISA coverage. Public Works and Planning staff have interpreted
that the 50%ISA limit applies to all new residential development/redevelopment throughout the City,
although the PUD provisions in Division 6 of the Land Development Regulations do not expressely
state that the 50% limit applies to PUDs. (Any new PUD approved after November 2001 has been
required to establish the ISA limit within the PUD documents.)
The property owner wishes to construct a 528 square foot (SF) addition to the rear of the existing
residence, which will result in a net 384 SF increase in impervious area and 65%ISA coverage on this
5000 SF lot. The property owner states a request was made to replace the 749 SF of concrete driveway
with brick pavers, which would have essentially compensated for the requested increase in ISA, but
was denied by her Homeowner's Association.
Section 24-46 (d) permits the Commission to authorize limited Waivers, on a case-by-case basis, from
.. specific provisions of the Land Development Regulations when it is demonstrated that compliance
with such provision would be unreasonable, in conflict with the public interest, or a practical
impossibility. In considering any request for such a Waiver, the Commission may require conditions
as appropriate to ensure that the intent of the Land Development Regulations is enforced.
The intent of the 50% ISA limit is to address stormwater and drainage impacts that may result from
over development of lots, particularly in areas of the City that do not have a master stormwater system
that has been permitted by the City and/or the St. Johns River Water Management District. While the
Selva Linkside subdivision is an older project, it does have an internal master stormwater system that
was permitted by the SJRWMD, and this system continues to function as designed and constructed. In
most cases, strict application of the 50% ISA limit would prohibit the construction of additions to
' residences within the Selva Linkside PUD. This may be unreasonable given that these homes are
rather small (1600 SF heated area). StafF does not consider that the addition of 384 SF of additional
ISA is likely to have adverse impacts to the stormwater system within Selva Linkside or the City at
large.
RECOMMENDATION: Consider approval of a waiver to the 50% ISA limit, allowing for a
maximum ISA of 65% for a lot located at 1629 Linkside Drive, North. However, Staff anticipates that
similar future requests, may come from Selva Linkside residents, but recommends that any such
request should be considered individually.
ATTACHMENTS: None.
