panels, and low-sloped roof applications, shall not be permitted.
F.
Variation in the architecture standards required in each district
may be granted by the Board of Commissioners by conditional use where
it is demonstrated that:
A.
Intent. Landscape and open space shall serve to: benefit environmental
well-being, including ecological and natural systems connectivity,
heat-island control, stormwater management and runoff; reduce visual
impacts of development on abutting properties and surrounding neighborhoods;
provide amenable exterior spaces for human use, including naturalistic
or formally defined outdoor rooms and sequences; and, support the
intentions of architectural and urban design character, massing and
spatial sequence.
C.
Landscape buffers shall, in the opinion of the Director of Building and Planning, provide a visual screen, as outlined in Chapter 135, Subdivision and Land Development, § 135-5.2D(4). Pedestrian access through the buffer shall not be limited.
[Amended 5-18-2022 by Ord. No. 4244]
D.
Landscape buffers shall be as required in the underlying district.
Additionally the following regulations apply:
(1)
Where required, landscape buffers shall be used for no other purpose than planting and screening, with the exception of pedestrian pathways, and shall conform to the landscape buffer requirements in Chapter 135, Subdivision and Land Development.
[Amended 5-18-2022 by Ord. No. 4244]
(2)
Access through buffer areas.
(a)
There shall be no more than one vehicular entrance and one vehicular
exit from each lot to any street.
(b)
A pedestrian accessway up to six feet in width may be provided
through a buffer area to improve connectivity.
(c)
Additional entrances and exits in the buffer area may be permitted
when authorized as a conditional use.
B.
Lighting of building and open spaces shall be compatible with streetlighting
of abutting streets. Outdoor lighting shall be designed, installed
and operated to prevent glare and excessive brightness from view on
abutting and nearby properties.
C.
Height of lighting sources for walkways, driveways and surface parking
areas shall not exceed 12 feet above surrounding/finished grade, unless
it can be demonstrated that taller lighting would not increase light
spillage or glare onto adjacent properties.
D.
Lighting sources for parking garage rooftop decks shall be shielded
to protect adjacent streets and properties from light glare. Interior
light sources within footprints along the perimeter of garages shall
not be visible from surrounding streets and properties.
A.
No tennis court or other hard-surfaced area designed or intended
to be used for sporting or other physical recreation activities shall
be constructed in any required setback.
B.
Artificial turf playing fields are regulated as follows:
(1)
They shall not be constructed in any required setbacks, except
an artificial turf field may be permitted in a front setback of a
primary road.
(2)
They shall not be considered as impervious surface if the artificial
field is designed to be permeable and the applicant can demonstrate
that the stormwater runoff coefficient of the artificial playing surface
is less than or equal to grass and the drainage system is maintained
to continue this runoff coefficient in the opinion of the Township
Engineer.
A.
Narrow lot development. In any residential subdivision made under the provisions of Chapter 135 of the Code of the Township of Lower Merion or with respect to any presently existing residentially zoned lot, the Board of Commissioners may authorize the creation of narrow lots as a conditional use subject to the following regulations:
(1)
The minimum lot width of the lot at the building line shall
be the minimum lot width required at the street line for lots in the
zoning district in which the lot is located. Minimum lot width shall
be measured parallel to the street at the point of the proposed building
closest to the street and shall extend the full depth of the building,
plus an additional 25 feet.
(2)
An applicant shall not be permitted to increase the number of
conforming lots permitted in a subdivision through the use of narrow
lots.
(3)
Every narrow lot shall include at least 20 continuous feet along
the street line, and such connection to the street shall extend at
no less than that width to the point at which the narrow lot reaches
the lot width required by the zoning district in which the lot is
located. The area between the street line and the point at which the
narrow lot reaches the required lot width shall be capable of providing
driveway and utility access to the lot (i.e., shall not be blocked
by natural barriers, such as lakes, or slopes in excess of 25%) and
shall not be excessively irregular in shape.
(4)
In calculating the lot area of a narrow lot, the area between
the street line and a line drawn radial to the point where the lot
attains the minimum lot width required in its zoning district shall
not be included in applying the requirements of this chapter, except
those requirements relating to impervious surfaces.
(5)
The Board of Commissioners has the right to designate which
of the required setbacks shall be the front setback for narrow lots.
(6)
In all cases, any narrow lot approved by conditional use shall
connect to the adjacent sanitary sewer, when and if it is installed.
B.
Impervious surface and expansion.
(1)
In the interest of public health, safety and welfare, the provisions
of this section and the impervious surface regulations, in general,
are intended:
(a)
To minimize stormwater runoff, street flooding and stream bank
and soil erosion caused by the conversion of undeveloped, porous surfaces
to impermeable ground cover.
(b)
To maximize groundwater recharge and maintain the base flow
of streams and watercourses, thereby ensuring both the quantity and
quality of groundwaters and surface waters.
(c)
To protect the Township from development which may cause a subsequent
expenditure for public works and disaster relief affecting the well-being
of the Township and its residents.
(d)
To protect the residents from property damage and personal injury
due to runoff, flooding and erosion attributable to nearby development.
(e)
To regulate erosion and sedimentation impacts and the alteration
of natural drainage patterns, aggravating flooding both in the immediate
area and in downstream areas.
(f)
To relate the intensity of development to the ability of the
natural and man-made environment to support it.
(2)
Total impervious surface shall not exceed that shown in the
underlying districts. Relief from maximum impervious surface requirements
may only be sought according to the regulations in this section.
(3)
The impervious surface on any lot in an LDR or MDR1 District
used exclusively as a dwelling may exceed the maximum permitted in
the underlying zoning district by an additional 5% of the lot area
or 1,500 square feet, whichever is less, provided that all of the
following requirements are met:
(a)
The additional 5% impervious surface shall not be permitted
on any lot where a new principal building has been constructed within
the prior 10 years, or where, during that same period, an addition
has been added to the principal building following the removal of
more than 75% of its building area.
(b)
100% of the direct volume of stormwater runoff from all impervious
surface exceeding what is permitted in the underlying zoning district
shall be recharged for a 100-year storm event.
(c)
The design and location of the recharge system shall be approved
by the Township Engineer. The Township Engineer may require that a
percolation test be submitted with the permit application showing
rates sufficient to empty the system within 24 hours. Construction
may not disturb steep slopes, woodlands or any area within the dripline
of trees greater than 15 inches dbh. Disturbance of trees between
six inches and 15 inches dbh is prohibited if an alternative location
for the recharge system is feasible. Every tree greater than six inches
dbh that is removed shall be replaced on the lot in accordance with Table 7.5.1, Tree Replacement, and the replacement trees shall be selected from the list of recommended trees set forth in § A177-1, or comparable tree approved by the Township Arborist. If the lot cannot accommodate all of the additional trees, the excess trees shall be planted on publicly owned land after receiving approval from the public entity having ownership.
(d)
The expansion shall only be permitted if site conditions allow
for on-site recharge.
(e)
A covenant running with the land shall be recorded requiring
the property owner to maintain the recharge basin at all times so
that it will operate as designed.
(f)
The property owner shall provide to the Township a certification
from a qualified engineer every five years that the stormwater management
system required by this section has been inspected and is functioning
as designed. If there is evidence the system is not functioning as
designed, the Township can require this inspection and certification
prior to the expiration of the five-year period.
[Added 12-2-2020 by Ord.
No. 4202]
(5)
The impervious surface within special districts may exceed the maximum permitted, subject to the regulations in Article VI, Special Districts.
(6)
For the purpose of determining the amount of impervious surface on a lot served by a common driveway with a length greater than 100 feet, the total impervious surface of that common driveway shall be allocated evenly among the lots served, unless it is otherwise allocated in a recorded covenant approved by the Township and binding on the properties affected, in which case such recorded allocation shall control. Shared driveways less than 100 feet in length shall not count towards impervious coverage for the portion that is shared and shall not be greater than the maximum permitted driveway width in Article VIII.
(7)
The following shall not be considered as impervious surface,
except in the IC3 and IE3 Districts:
(a)
Wood decks less than 200 square feet if constructed with a space
between each plank and if the deck is constructed over a pervious
surface. Once the deck exceeds 200 square feet, one-half of the entire
deck area shall be considered impervious surface.
(b)
Pathways six feet or less in width that employ a porous paving
system and which are not intended for automobile use.
A.
All outdoor storage, electrical, plumbing, mechanical, communications
equipment and appurtenant enclosures, trash dumpsters and loading
areas shall be located in compliance with required setbacks for buildings,
shall be located behind the line of the facade, and screened from
view from any frontage and from any abutting residential property,
except across an alley. These shall not be allowed as encroachments
on any setback, except for those existing at the effective date of
this Code.
(1)
Transformers shall comply with these requirements unless regulated
by the Public Utility Commission (PUC) and required by the authority
having jurisdiction under the PUC to be located closer to the street
than the front facade of the building. If a transformer is located
closer to the street as described above, the transformer shall be
screened from view from the street with plantings and/or structural
elements approved by the Township.
