If a column or other obstruction is adjacent to a parking space and
would interfere with car door openings, then the minimum stall width
of that space shall be increased by one foot. The inner face of the
column or other obstruction shall form the actual boundary of the
space when measuring the width or length of the spaces.
C.
Each standard-size angled parking space shall be a parallelogram having minimum dimensions in accordance with the table contained in Subsection A above. An angled parking space is one in which the acute angle formed by the intersection of the long side of the space and the curb is between 45° and 75°. The width of an angled parking space is measured parallel to the curb or travel lane along the short side of the parallelogram, and the length of the space is measured along the side of the parallelogram from the curb to the travel lane.
D.
Each small-car automobile parking space shall have minimum dimensions in accordance with the table contained in Subsection A above. Small-car spaces may be provided for up to 10% of all required spaces for nonresidential uses. Small-car space shall be limited to parallel or perpendicular parking angles.
[Amended 5-7-2008 by Bill No. 2008-01]
E.

nor exceed 24 feet in width for two-way traffic, except that ten-foot-wide
driveways are permissible for two-way traffic when:
[Amended 5-7-2008 by Bill No. 2008-01]
C.
Driveways through Resource Protection Zone (RPZ), wetland or other
conservation areas should be designed as narrow and as close to grade
as feasible, with minimal or no shoulder or curbing, and with canopy
closure to allow for continuous wildlife migratory corridor. Protective
bollards and signage shall be provided to alert drivers to the wildlife
crossing area. Stormwater runoff shall be treated prior to entering
the conservation area.
[Added 5-7-2008 by Bill No. 2008-01]
A.
No structure shall be erected, substantially altered or its use changed
unless permanent off-street parking and loading spaces have been provided
and maintained in accordance with the provisions of this section.
B.
Parking and loading requirements based on floor area shall be determined
by the total gross floor areas of the use, excluding incidental storage
and mechanical areas. "Incidental storage" is storage that is subordinate
and nonessential to the main use.
[Amended 5-7-2008 by Bill No. 2008-01]
C.
Parking and loading requirements per seat shall be determined by
the number of individual seats, except as otherwise required. For
purposes of bench-type seating, 20 inches shall be the equivalent
of one seat.
D.
Parking requirements may be provided in attached or detached garages,
in off-street parking lots or on parking pads on the lots. No more
than 75% of the total number of garage spaces provided for single-family
attached or multifamily dwellings units may be counted towards the
minimum requirements of Figure XX-1.[1] Multifamily dwelling unit garage spaces can be exempted
form the 75% limitation so long as the use specifically prohibits
the use of garage for storage.
[Amended 7-8-1997 by Ord. No. 97-83; 5-7-2008 by Bill No. 2008-01; 9-21-2021 by Bill No. 2021-02]

Editor's Note: Figure XX-1, Table of Off-Street Parking Requirements, is included as an attachment to this chapter.
E.
Unless no other practicable alternative is available, parking areas
shall be designed so that, without resorting to extraordinary movements,
vehicles may exit such areas without backing onto a public street.
This requirement does not apply to parking areas consisting of driveways
along a local street that serve one or two dwelling units.
F.
Access must be provided and shall be designed so that sanitation,
emergency and other public service vehicles can serve such developments
without the necessity of backing unreasonable distances or making
other dangerous or hazardous turning movements.
G.
Every parking area shall be designed so that vehicles cannot extend
beyond the perimeter of such area onto adjacent properties or public
rights-of-way. Such areas shall also be designed so that vehicles
do not extend over sidewalks or tend to bump against or damage any
wall, vegetation or other obstruction.
H.
Circulation areas shall be designed so that vehicles can proceed
safely without posing a danger to pedestrians or other vehicles and
without interfering with parking areas.
I.
Any lighting used to illuminate off-street parking areas shall be
arranged so as to reflect away from any adjoining residential zone
or uses and any public or private right-of-way.
K.
All parking areas shall be drained so as to dispose of all surface
water within the parking area without carrying said water accumulation
over a public sidewalk of a public travelway.
L.
Permanent stormwater retention shall be provided for all off-street
parking areas as required in the County's Stormwater Management Ordinance.[2] Bioretention areas are encouraged and shall be considered
to meet landscaping requirements. If a stormwater management pond
is proposed, it shall be integrated into the overall development and
serve as a visual amenity to the site.
[Amended 5-7-2008 by Bill No. 2008-01]
M.
Stormwater management facilities, such as ponds and bioretention
areas, are permitted within building setbacks, provided that they
are designed as attractive, landscaped amenities. Designs that rely
on chain link fencing to ensure safety, rather than sloop contouring
and vegetation, are not permitted within setbacks.
[Added 5-7-2008 by Bill No. 2008-01]
N.
The percentage of coverage of parking areas and driveways shall not
exceed 40% of the total required front yard or side street side yard,
excluding single-family attached residential uses.
[Amended 5-7-2008 by Bill No. 2008-01; 9-21-2021 by Bill No. 2021-02]
O.
The total coverage of parking areas and driveways, in all zones except
for residential use in the RC, RC(D), and AC, shall use the following
mitigation options individually or in combination:
[Added 5-7-2008 by Bill No. 2008-01]
(1)
Industry standard pervious pavement installed to manufacturer's
specifications;
(3)
On-site pocket park(s), integrated into commercial, industrial
and institutional parking areas, on an equal square-foot-basis ratio
(minimum 2,500 square feet each).
(4)
All stormwater runoff is filtered through bioretention facilities;
(5)
Structural green roof provided on an equal square-foot basis
subject to a standard stormwater management triennial maintenance
agreement; and/or
(6)
Structured parking.
P.
If structured parking is entirely underground, the applicant shall
be relieved from providing the required off-street parking landscaping
and can locate the underground structure within any part of the setback
and yard areas.
[Added 5-7-2008 by Bill No. 2008-01[4]]
Q.
Off-street parking facilities shall, whenever possible, be located
within the required rear and side yards of any commercial, office/residential
or industrial zone.
R.
Commercial, institutional, marine, recreation, services and industrial
uses shall provide a minimum of three parking spaces.
S.
The Board of Appeals may authorize a variance to reduce the number of parking spaces required, if the requirements of § 297-412 are satisfied. In no case shall the Board grant a variance of more than 10% of the number of required parking spaces.
T.
Residential parking areas shall not serve as general circulation
for more than 150 dwelling units per access to a public road.
[Added 5-7-2008 by Bill No. 2008-01]
U.
Pedestrian circulation systems within parking areas shall be clearly
delineated by the use of pavement markings or changes in surface materials
and be constructed of pervious materials.
[Added 5-7-2008 by Bill No. 2008-01]
A.
Parking areas that include lanes for drive-in windows or contain
parking areas that are required to have more than 10 parking spaces
and that are used regularly at least five days per week shall be graded
and surfaced with asphalt, porous asphalt, concrete, porous concrete,
brick or concrete pavers, or other suitable material that will provide
equivalent protection against potholes, erosion and dust.
[Amended 5-7-2008 by Bill No. 2008-01]
B.
Parking areas that are not provided with the type of surface specified in Subsection A shall be graded and surfaced with crushed stone, gravel, structural grass pavers, concrete honeycomb pavers, or other suitable material to provide a surface that is stable and will help to reduce dust and erosion. The perimeter of such parking areas shall be defined by bricks, stones, railroad ties or other similar devices. In addition, whenever such a parking area abuts a paved street, the driveway leading from such street to such area (or, if there is no driveway, the portion of the parking areas that opens onto such streets) shall be paved as provided in Subsection A for a distance of 15 feet back from the edge of the paved street. This subsection shall not apply to single-family or two-family residences that are required to have only one or two parking spaces.
[Amended 5-7-2008 by Bill No. 2008-01]
D.
Parking areas shall be properly maintained in all respects. Parking
area surfaces shall be kept in good condition and functioning properly
in the case of porous paving (free from potholes, cleaned regularly,
etc.), and parking space lines or markings shall be kept clearly visible
and distinct.
[Amended 5-7-2008 by Bill No. 2008-01]
[Amended 7-25-2005 by Bill No. 2005-01]
A.
Where a parking area provides spaces collectively for several uses located on the same or different parcels, the parking spaces required shall equal the sum of the requirements for the various uses computed separately; and the required space for one use may not be credited to another use except as provided in Subsection B.
B.
The required space for one use may be credited to another use.
(1)
Two methods may be used to determine shared parking:
(a)
Parking Occupancy Rate Table: When any land and/or buildings
are contiguous to one another and are used for two or more purposes,
the number of parking spaces shall be computed by multiplying the
minimum required parking spaces by the appropriate percentage as shown
on the following parking chart[1] for each time period shown. Then the resulting total number
of spaces required for each use during each time period is totaled.
The time period that generates the highest number of parking spaces
becomes the parking requirement for the shared parking.
[Amended 5-7-2008 by Bill No. 2008-01]
[1]
Editor's Note: The Parking Occupancy Rate Table is included as an attachment to this chapter.
(b)
Local parking study. A parking demand analysis, prepared by
a qualified parking or traffic consultant, may be used to show the
feasibility of shared parking. The analysis shall determine parking
occupancy rates of morning, afternoon and evening peaks on the seven
different days of the week. In the case of new construction or addition
of new uses, the surveys shall observe another circumstance with similar
mixed uses. A combination of similar circumstances may be necessary
to cover all the proposed land uses. The approximate square footages
of the various land uses of the specimen projects shall be compared
to the proposed project to allow the ratios of uses to be rated accordingly.
In the case of an enlargement or substitution of existing uses, the
survey shall document the occupancy rates of the existing parking
facility.
(2)
The shared parking facility must be owned by the same owner
or must be the subject of a shared parking agreement made between
different owners of the properties involved.
(3)
Handicapped parking may not be shared or included in any shared
parking calculations.
A.
If the number of off-street parking spaces required by this chapter
cannot reasonably be provided on the same lot where the principal
use associated with these parking spaces is located, then spaces may
be provided on adjacent or nearby lots in accordance with the provisions
of this section. These off-site spaces are referred to in this section
as "satellite parking spaces."
B.
All such satellite parking spaces (except spaces intended for employee
use) must be located within 400 feet of a public entrance of a principal
building housing the use associated with such parking or within 400
feet of the lot on which the use associated with such parking is located
if the use is not housed within any principal building. Satellite
parking spaces intended for employee use may be located within any
reasonable distance. No more than 25% of the total required spaces
are to be located in satellite parking spaces.
C.
The applicant wishing to take advantage of the provisions of this
section must present satisfactory written evidence of the permission
of the owner or other person in charge of the satellite parking spaces
to use such spaces. The applicant must also sign an acknowledgement
that the continuing validity of the permit depends upon continuing
ability to provide the requisite number of parking spaces.
D.
All satellite parking spaces shall be located in the same zone as
the structures or uses served.
E.
Satellite parking spaces shall be used solely for the parking of
passenger automobiles. No commercial repair work or service of any
kind shall be conducted, and no charge shall be made for parking.
No sign of any kind, other than designating ownership, entrances,
exits and conditions of use, shall be maintained on such satellite
parking areas.
F.
Each entrance and exit to and from such parking area shall be at
least 20 feet distant from any adjacent lot line located in any residential
zone.
G.
The satellite parking areas shall be subject to all requirements
of this chapter concerning surfacing, lighting, drainage, landscaping,
screening and setbacks.
A.
Any increase in the intensity of use of any structure shall mean
the addition of dwelling units, employees, gross floor area, seating
capacity or any other unit of measurement used as a basis for determining
required parking facilities. When the intensity of use of any structure
or site is increased by less than 20%, parking facilities shall be
provided for the increase, but not for any existing deficiency in
such facilities. When the intensity is increased by more than 20%,
including consecutive increases from the date of this chapter, parking
facilities shall be provided for the entire structure or premises.
[Amended 5-7-2008 by Bill No. 2008-01]
B.
When the use of any structure or premises is changed to a different
use, parking facilities shall be provided for the different use.
C.
Notwithstanding any other provisions of this chapter, whenever there exists a lot with one or more structures on it constructed before the effective date of this chapter, a change in use that does not involve any enlargement of a structure is proposed for such lot and the parking requirements of § 297-335 that would be applicable as a result of the proposed change cannot be satisfied on such lot because there is not sufficient area available on the lot that can practicably be used for parking, then the applicant need only comply with the requirements of § 297-335 to the extent that the parking space is practicably available on the lot where the development is located and satellite parking space is reasonably available as provided in § 297-341. However, if satellite parking subsequently becomes reasonably available, then it shall be a continuing condition of the permit authorizing development on such lot that the applicant obtain satellite parking when it does become available.
[Amended 5-7-2008 by Bill No. 2008-01]
A.
Subject to Subsection E, whenever the normal operation of any development requires that goods, merchandise or equipment be routinely delivered to or shipped from that development, an off-street loading and unloading area must be provided in accordance with this section to accommodate the delivery or shipment operations in a safe and convenient manner.
B.
The following table indicates the number and size of spaces which
