The regulations included in this article shall apply to all
uses in all districts.
The following standards shall apply to all grading and disturbance
of land with slopes of 15% or greater. If any of the delineated steep
slope areas include soils or geological features which indicate possible
instability, the additional standards contained in the Allegheny County
SALDO, § 780-510A, shall apply.
A.
Slopes between 25% and 40%. No more than 30% of slope areas with
existing grades between 25% and 40% shall be stripped of vegetation
or disturbed though grading. Grading and clearing for roads on these
slopes shall be limited to that necessary to accommodate the cartway
and shoulders or berms. Wherever possible, roads should follow the
contours of the land.
B.
Slopes between 15% and 40% located within "greenprint" areas, as
defined in Allegheny Places. No development.
C.
Slopes exceeding 40%. No development or disturbance shall be allowed
on slopes exceeding 40%. Limited disturbance for utilities may be
allowed where no reasonable alternative location exists.
No impervious surfaces, including asphalt or concrete paved
areas for parking, access driveways, pedestrian access walkways and
rock-lined stormwater detention facilities, shall exceed 85% of the
lot area or site area of the lot or parcel upon which said improvements
are installed. Wherever there are conflicting standards in any specific
zoning district requirements or express standards and criteria for
uses allowed by conditional use approval, the zoning district or conditional
use standards shall apply.
For single-family development on an individual lot, provide
street trees in accordance with the following standards:
A.
Street trees shall be provided along the entire length of the street
right-of-way on both sides of the street if the street lies within
the development.
B.
Street trees in residential subdivisions shall be located within
five feet of the right-of-way and in nonresidential developments between
the right-of-way and the building line. An easement shall be granted
to the Borough for the purpose of maintaining the trees, and a restrictive
covenant shall be placed in the deed for the property, prohibiting
removal of the trees by the property owner.[1]
C.
Street trees shall be located so as not to interfere with the maintenance
of utilities, required sight distances and visibility of street and
traffic signs.
D.
The species chosen shall be appropriate to the location. Factors
such as microclimate, soils, habit of growth, salt, air pollution
and disease tolerance, proximity of sidewalks and overhead utility
lines, and social conditions (likelihood of soil compaction, vandalism,
damage to by dogs, deer, etc.) shall be considered. Tree species shall
be selected that do not have root structures that may damage adjacent
sidewalks or utilities.
E.
Street trees shall have the following minimum calipers at the time
of planting:
(1)
"Large trees," defined as those trees whose height will ultimately
exceed 40 feet, shall have a minimum caliper of 2.5 inches to 3.0
inches DBH.
(2)
"Medium trees," defined as those trees with an ultimate height of
25 to 40 feet, shall have a minimum caliper of 2.0 inches to 2.5 inches
DBH.
(3)
"Small trees," being those trees whose ultimate height will not exceed
25 feet, shall have a minimum caliper of 1.5 inches to 2.0 inches
DBH.
F.
Street trees shall be spaced with regard to the ultimate spread of
the fully developed canopy. Spacing requirements are as follows:
G.
Tree grates and/or permanent fencing maybe required, protecting new
street trees in areas of dense development or high use.
H.
Mature trees, woodlands or other significant vegetation which remains
undisturbed adjacent to the street right-of-way may be used in place
of or in conjunction with the requirements of this section.
I.
Pervious pavement shall be utilized where necessary to provide water
infiltration to support tree growth.
A.
No fence, wall or other obstruction, whether open or solid, decorative
or otherwise, shall be erected in any public right-of-way except by
special exception.
B.
Fence or wall erected in the required front yard setback areas shall
be no taller than four feet in height and be at least 50% open.
C.
No fence or wall or other obstruction shall be over six feet in height
if erected within any rear or side yard area in any zoning district.
D.
Any fence in any district shall have its most finished or decorative
side facing the adjacent lot or street, with all posts being on the

after the adoption of this chapter shall be provided with off-street
parking spaces as set forth in this chapter.
B.
The provisions of this section, except where there is a change of
use, shall not apply to any existing building or structure.
C.
Whenever a building or structure constructed before the effective
date of this section is changed or enlarged in floor area, number
of employees, number of housing units, seating capacity or otherwise
to create a need for an increase in the number of parking spaces,
additional parking spaces shall be provided on the basis of the enlargement
or change. If a building or structure existing prior to the effective
date of this section is enlarged to the extent of 50% or more in floor
area or number of housing units, it shall then and thereafter comply
with the full parking requirements set forth herein.
D.
Off-street parking facilities in existence on the effective date
of this section and located on the same lot as the building or use
served shall not hereafter be reduced below the requirements for a
similar new building or use under the provisions of this section.
E.
The following regulations shall govern the location of off-street
parking spaces and areas:
(1)
Parking spaces for all detached residential uses shall be located
on the same lot as the use which they are intended to serve. Each
required off-street parking space shall have direct access to a public
right-of-way.

along any building facade adjacent to a parking area or drive aisle.
(2)
Internal streets. All off-street developments with greater than 200
parking spaces shall include an internal street system to facilitate
pedestrian and vehicular circulation, creating an interconnected circulation
network.
I.
Common shared parking lots. Common shared parking lots are preferred
and encouraged. The required off-street parking spaces for two or
more uses may be provided collectively on one lot if the total number
of spaces is not less than the sum of the spaces required for each
use individually.
(1)
The developer shall provide a parking and access easement agreement
between the owners and operators of the facilities generating the
need for common shared parking lots.
(2)
Any modification to the required number of parking spaces shall be
supported by a parking needs analysis documenting anticipated parking
needs based on the combined utilization of all facilities on site
simultaneously or demonstrating that the hours or days of peak parking
needed for the uses are so different that a lower total will adequately
provide for all uses served by the facility. The parking needs analysis
shall be prepared by a person or firm trained or certified to perform
such studies.
J.
When two or more uses are located within the same building or structure,
off-street parking spaces equal in number to the sum of the separate
requirements for each use shall be provided.
K.
All off-street parking lots required by this section shall be used
only for the parking of vehicles of occupants, patrons, visitors,
