sites where alternate side yard areas apply(see"Yards"table),the following special restrictions also apply:(A)there
must be a driveway located as nearly as practicable to one side of the site;(B)the side is determined in accordance
with the established driveway pattern for the block face in question,if there is such a pattern;and(C)if there is no such
pattern,and if there is an adjacent driveway on one adjoining building site but not the other,the driveway must be on
the side farthest from the adjoining driveway.Exceptions:(i)this paragraph does not prohibit circular driveways
specifically permitted under another ordinance of the City,and(ii)a driveway may be curved or moved away from the
most direct route to the extent reasonably necessary to avoid destroying or seriously injuring a tree.
Note 7.Special Exceptions.The ZBA may issue a special exception for a parking area,garage or driveway(or other maneuvering
area)in another location or with a different design than prescribed by this ordinance,if it finds that:(i)the other location
or design will not unreasonably interfere with available light and air and will not significantly alter access for fire-fighting
and similar needs;(ii)the other location or design will prevent the destruction of a qualified tree;(iii)in the case of the
remodeling of a principal building,the location requested is the same location as an existing parking area,garage or
driveway;or(iv)the location or design requested is necessary for safety considerations.
Note 8.Curb Cuts in PDD-TH1.(i)If a building site abuts both Bellaire Boulevard and another street,then all vehicular access
shall be from the other street,and no more than two curb cuts shall be allowed. However,in the case of the
development of Lots 6,7,8,9 and the east ten feet of Lot 10,Block 1,Kent Place Addition,if Lot 6 is included in the
same building site or in a joint development with the other lots,vehicular access shall be limited to one curb cut on
Mercer Street.(ii)If a building site abuts only Bellaire Boulevard,vehicular access shall be limited to two curb cuts.
Note 9. Curb Cuts in PDD-TH5.(i)If a building site abuts both Academy and Bissonnet,no curb cuts on Bissonnet and no more
than two curb cuts on Academy are permitted.(ii)If a building site abuts only Bissonnet,there may be no more than
two curb cuts.
Note 10.Driveways in PDD-TH7.Cul-de-sac driveways in PDD-TH7 may not exceed 50 feet in length,or 200 feet if a terminus is
provided with dimensions adequate for turning.
Note 11. Curb Cuts in PDD-TH2.(i)If a building site abuts both Kirby Drive and another street,there may be one curb cut on Kirby
Drive and on each other abutting street.(ii)If a building site abuts only Kirby Drive,vehicular access shall be limited to
two curb cuts.
Note 12. Curbs as Wheel Stops.Curbs may be used as wheel stops.Area outside a curb-wheel stop counts toward minimum
parking space dimensions if actually usable as"overhang"and not needed for maneuvering area.
Sec. 70-27. - Curb cuts and driveways; concrete. ..''
(a) Curb cuts, etc. Only one curb cut and only one driveway is allowed along the front street
line of any building site less than 60 feet wide, measured along the front street line.
Agenda Item 3 04-12-2012 Driveways and Curb Cuts
(b) Two or more curb cuts. If there are two or more con cted curb cuts or driveways on a
building site (for example, when there is a circular or semi-circular driveway), the following
apply:
(1) At the front street line, no part of a curb cut or driveway may be closer than two
feet to a side property line. In the street area, no part of the curb cut or driveway may
cross the imaginary extension of a side property line, unless the affected neighboring
owner consents in writing. The building official may make exceptions to these rules
when there is no practical alternative or when necessary to prevent harm to a tree.
(2) Measured along the edge of the main traveled roadway: (p
a. The opening width of the driveway anted urb cu1`�, ,ieet;
b. The inside edges must be at least NA.febt apart; and
c. The width of the "island" area may be covered with hard surface , ; +; ;
and
d. The curb cuts must be located along the front street line. X.-) Q
(3) No driveway may be wider than 14-feet---- \ Q
(4) Within the street area, the edges of each driveway must be perpendicular to the/
edge of the main traveled roadway. 10° Q�
XS
(c) "Open ditch"areas, culverts. If a driveway is connected to a roadway where there is no tk
curb and gutter, there must be a concrete culvert beneath the driveway. The inside diameter
of the culvert must be at least 12 inches, and the length must be at least 14 feet. The public
works director may eliminate or modify the culvert requirement at a specific location, but only
to the extent the specified culvert is not necessary for adequate area drainage.
(d) Reinforcement. All concrete used in constructing driveways shall be reinforced by using,
at a minimum, one of the following:
(1) #3 deformed steel reinforcing bars spaced 12 inches or closer; or
(2) #4 deformed steel reinforcing bars spaced 16 inches or closer.
Sidewalks outside driveway areas may be reinforced by one of these methods or by 6x6x6
wire mesh, at a minimum.
(e) Certain temporary driveway permits. The director is authorized to issue permits for
temporary driveway access to a site, if primary access to the site is interrupted by
construction or another temporary condition. In addition to the requirements of section 8-104
of the zoning ordinance, appended in this Code, such a permit must require:
(1) Barricading or removal of any temporary driveway on a residential street within
24 hours following resumption of primary access to the site; and
(2) Restoration of each area affected by temporary driveway access to its pre-
existing condition, within 14 days following resumption of primary access to the site.
Such a permit may also contain additional restrictions and conditions designed to reduce
impacts on street areas, utilities, nearby land uses or traffic.
