TO: South Burlington Development Review Board
FROM: Marla Keene, Development Review Planner
SUBJECT: SP‐20‐016 and SP‐20‐017 362 & 430 Meadowland Drive
DATE: April 7, 2020 Development Review Board meeting
Don Stewart has submitted sketch plan application #SD‐20‐15 to amend a previously approved plan for an
airport complex. The amendment consists of constructing a 17,200 sf two‐story addition to an existing 39,200
sf one‐story existing hangar/office building, reconfiguring the adjacent parking area, and related site
improvements, 1150 Airport Drive.
The Board reviewed the sketch plan application on May 5, 2020 and continued the meeting to May 19, 2020 for
the purpose of taking additional testimony pertaining to the location of parking and front setback coverage.
The applicant has submitted two alternative site configurations, included in the packet for the Board. Members
are directed to the May 5, 2020 packet for originally submitted application materials.
This project is located south of the existing airport terminal driveway and north of the Heritage Aviation
building reviewed by the Board at a sketch plan level on 4/21/2020. An aerial image is provided below.

Based on the aerial image, there are three elements of the Project area to which Staff wishes to draw the
Board’s attention.
1. Including the parking spaces south of the existing building, there are approximately 110 parking spaces
currently available. The small building located to the south of the subject building is a sewer pump
station located inside the Airport’s security fence and not occupied. The parking spaces south of the
existing building are not within the applicant’s designated project area and are not anticipated to
change. They are, to Staff’s knowledge, available for use by this building.
2. There is a substantial amount of existing mature landscaping in the front setback.
3. Though there may be informal cut‐through traffic today, the curb cut the applicant is proposing to use
to the north is blocked by existing parking spaces and is not currently shared by the subject building.
This application is subject to planned unit development standards and site plan review standards. The purpose
of requiring PUD review is
…to encourage innovation of design and layout, encourage more efficient use of land for
development, promote shared parking opportunities, provide coordinated access to and from
commercial developments via public roadways, and maintain service levels on public roadways with
a minimum of publicly financed roadway improvements (6.05A).

As emphasized by members at the May 5 hearing, the Board’s responsibility is to review the proposed use and
site configuration, and in the case of a PUD, the proposed building, for compliance with the regulations,
regardless of tenant.
There were two topics which the Board considered warranted further discussion, that pertaining to parking ,
and that pertaining to front setback coverage. Staff has also included a brief discussion of landscaping as it
pertains to these two topics.
14.06B(2) Parking
(a) Parking shall be located to the rear or sides of buildings. Any side of a building facing a public
street shall be considered a front side of a building for the purposes of this subsection.
(b) The Development Review Board may approve parking between a public street and one or more
buildings if the Board finds that one or more of the following criteria are met. The Board shall approve
only the minimum necessary to overcome the conditions below.
(i) The parking area is necessary to meet minimum requirements of the Americans with
Disabilities Act;
(ii) The parking area will serve a single or two‐family home;
(iii) The lot has unique site conditions, such as a utility easement or unstable soils, that allow
for parking, but not a building, to be located adjacent to the public street;
(iv) The lot contains one or more existing buildings that are to be re‐used and parking needs
cannot be accommodated to the rear and sides of the existing building(s);
(v) The principal use of the lot is for public recreation; or
(vi) The lot is located within the Mixed Industrial‐Commercial Zoning District… (n/a)
(vii) The lot is located within the Mixed Industrial‐Commercial or Industrial & Open Space
Zoning Districts… (n/a)
(c) Where more than one building exists or is proposed on a lot, the total width of all parking areas
located to the side of building(s) at the building line shall not exceed one half of the width of all
building(s) located at the building line. Parking approved pursuant to 14.06(B)(2)(b) shall be exempt
from this subsection.
(d) For through lots, parking shall be located to the side of the building(s) or to the front of the
building adjacent to the public street with the lowest average daily volume of traffic. Where a lot abuts
an Interstate or its interchanges, parking shall be located to the side of the building(s) or to the front
adjacent to the Interstate. Parking areas adjacent to the Interstate shall be screened with sufficient
landscaping to screen the parking from view of the Interstate.
The airport PUD generally consists of one lot. The Board has historically required applicants for the airport PUD
to submit a parking needs analysis to demonstrate adequacy of parking. As recently as April 7, 2020 at a sketch
plan meeting pertaining to the proposed airport hotel, the airport has stated that the existing parking garage is
at approximately 90% capacity on peak days, and nearer to 60% capacity on normal days. Though parking
minimums no longer apply to this use, the Board is still responsible for determining whether proposed parking
is adequate (14.06B(1)). As noted above, there are approximately 110 parking spaces around the existing
building. The applicant is proposing to impact approximately 81 of those parking spaces, to a greater or lesser
degree depending on location.
On May 5, the Board directed the applicant to consider an alternative front parking configuration that better

complied with the requirements above, specifically that parking between a building and a street shall only be
approved to the minimum degree necessary to overcome the allowable exemptions. Staff considers the
relevant exemptions to be (i) The parking area is necessary to meet ADA requirements, and (iv) the lot contains
one or more existing buildings that are to be re‐used and parking needs cannot be accommodated to the rear
and sides of the existing building. Staff considers the other exemptions to be not applicable but has included
them to round out the Board’s understanding of the intent of the exemptions.
The applicant has provided two conceptual sketches showing a revised front parking configuration. In both, the
applicant has slightly modified the parking lot to the southwest of the building and it appears they have
standardized its dimensions to comply with Table 13‐2. These modifications have resulted in three (3) fewer
parking spaces in this area compared to existing conditions, and an increase in non‐conforming parking area
along the rear of the parking lot of about 1,300 sf.
In the first concept, the applicant has expanded parking in the lot west of the building by about 1,400 sf. this
expansion is due to the addition of six spaces north of the lot. They have also removed three spaces along the
rear of the lot totaling about 600 sf. Based on previously provided concepts, Staff expects this area would be
replaced by landscaping. This concept results in approximately 7 fewer parking space west of the building than
under existing conditions.
In the second concept, the applicant has expanded parking in the lot west of the building by about 2,600 sf.
This expansion is due to an increase in green space along the building from 10‐ft to 15‐ft, and the addition of six
spaces to the north of the lot. Compared to the previously presented alternative, the applicant has generally
retained the existing parking configuration while standardizing the dimensions to comply with Table 13‐2. This
concept results in approximately 4 fewer parking space west of the building than under existing conditions.
With the exception of the six additional parking spaces to the north, discussed below, Staff considers either
configuration, if completed in a manner which complies with the requirements of 13.01 to screen all parking
areas from the street by fencing, walls or vegetation measuring three (3) feet in height, may not significantly
alter the appearance of the site from the street and therefore the Board may wish to consider them as
allowable under the exemptions in 14.06B(2) above.
1. Staff recommends the Board provide feedback to the applicant that either of these configurations
(excepting the six spaces to the north) would be acceptable.
Staff considers the six additional parking spaces to the north along the proposed connection to the adjacent
curb cut represent a significant expansion of the existing nonconformity. Staff considers there two important
factors leading to this conclusion.
First, as noted above, the applicant is proposing a new connection to this existing curb cut. The LDR
generally encourages shared access between properties. Since the proposed connection is to an existing
curb cut, Staff considers this is not necessarily an undesirable connection, but because this is a new
connection, it should not be considered as an existing condition warranting consideration under 14.06B(2).
Second, 14.06B(2) states that the Board shall approve only the minimum parking between the street and
building necessary to overcome the conditions of 14.06B(2). The purpose of requiring PUD review in the
airport industrial district includes the promotion of shared parking opportunities. As the airport has
testified, there is ample parking available on the airport PUD, and therefore less emphasis should be placed
on retaining the exact number of existing spaces.
2. Staff recommend the Board provide feedback to the applicant that these six spaces are unlikely to be
allowed.

3.06H Front Setbacks for Non‐Residential Uses. In the case of nonresidential uses, not more than thirty
percent (30%) of the area of the required front setback shall be used for driveways and parking and the
balance shall be suitably landscaped and maintained in good appearance. Design approaches that that use
landscaping elements in the front setback which enhance stormwater infiltration or management are
encouraged. No portion of the required front setback shall be used for storage or for any other purpose
except as provided in this section. In addition, a continuous strip fifteen (15) feet in width traversed only by
driveways and sidewalks shall be maintained between the street right‐of‐way line and the balance of the lot,
which strip should be landscaped and maintained in good appearance. This provision shall apply also to yards
that abut a right‐of‐way designated for a future street.
On May 5, the Board discussed whether they would consider this standard applicable to the airport PUD as a
whole or to the project site. Upon further research, Staff wishes to call the Board’s attention to section 6.05B
pertaining to multiple structures and uses within airport and industrial districts.
Multiple structures, multiple uses within structures, and multiple uses on a subject site may be
allowed, if the Development Review Board determines that the subject site has sufficient frontage,
lot size, and lot depth. Area and frontage requirements may be met by the consolidation of
contiguous lots under separate ownership. Construction of a new public street may serve as the
minimum frontage requirements. Where multiple structures are proposed, maximum lot coverage
shall be the normal maximum for the applicable districts.
3. Because area and frontage requirements may be met by consolidating continuous lots in these districts,
and taking into consideration the improved parking configuration, Staff recommends the Board consider
front setback coverage for the airport PUD as a whole, rather than on a site by site basis.
Landscaping
There are a number of mature trees located within the front setback, which the applicant has identified on
their provided plans. Trees that were planted as part of an approved landscaping plan must be replaced if
removed. The applicant’s first configuration appears to allow preservation of all of these trees, while the first
configuration impacts three of them.
4. Staff recommends if the Board considers all other factors equal that they express a preference for the
first configuration because of it’s inherent tree preservation.
RECOMMENDATION
Staff recommends the Board discuss the project with the applicant and conclude the meeting.
