Prior to filing a formal application, the applicant is encouraged
to meet with the Planning Administrator (who shall invite representatives
of other departments to be present) to discuss the concepts and issues
related to the proposed subdivision. The applicant should bring the
following to the introductory meeting:
A. Any professional representatives which are engaged to work on the
project.
B. Written documentation regarding the project.
C. A sketch plan depicting the project. It is helpful if the sketch plan includes as many of the items listed in §
640-27 below as possible.
D. A willingness to candidly discuss the project with planning staff
in a nonbinding manner to ascertain the goals, objectives, opportunities,
and limitations of both the City and the applicant.
Prior to filing a formal application, the applicant may, at
his or her option, submit a sketch plan for a more technical interdepartmental
review by City staff. This review is not binding on the Planning Commission
but allows the applicant to work out many of the technical issues
which typically accompany a subdivision plan. The review takes approximately
15 to 30 days, depending on the issues at hand and ability to communicate.
To engage this review, the applicant shall submit the following:
A. A brief narrative of the project, which includes a request for a
preapplication review of the plans under this section.
B. A contact list of professionals working on the project (if hired),
the owner, and the applicant submitting the project.
C. A list of waivers the project will likely need for approval.
D. The fee established by resolution of the City Council from time to
time. This amount will be subsequently deducted from the filing fee
required for the formal application.
E. A sketch plan. The sketch plan shall include at least the following:
(1) The title: "Sketch Plan of (name of subdivision)."
(2) Date, scale, North point, and if appropriate, a legend to explain
any graphic representations or symbols on the plan.
(3) The names of the owner of record and the applicant.
(4) The name of the draftsman (this need not be a design professional).
(5) The outer lines of the subdivision in a heavy shaded line.
(6) The names, location, alignment, and width of existing streets and
easements.
(7) Lines and names of proposed streets and easements in a general manner.
(8) The following information for each lot within the subdivision boundaries:
(a)
Approximate boundary lines.
(b)
Approximate dimensions, including area and frontage.
(c)
A numerical designation for each lot, preferably in sequential
order.
(9) The topography in a general manner.
(10)
A rough sketch of the proposed drainage system in a general
manner.
(11)
Identification of any existing or proposed public areas.
(12)
The approximate size and location of new and existing utilities.
(13)
Any additional items required for a formal proposal which may
be helpful in the staff's review of the plan.
(14)
Any other information the applicant feels would be helpful in
the review.
Neither the introductory meeting nor the preapplication review have standing as part of the formal review process. Approval of plans under this Article requires action by the Altoona City Planning Commission, which is specifically and deliberately absent from the processes described in §
640-26 and §
640-27. The purpose of these processes is to familiarize the staff and work out technical kinks in the proposal before it enters into the formal review process. No comments made by staff during these processes are binding on the Planning Commission for its review; however, staff is hereby required to act expeditiously and in good faith in its representations to the applicant. The applicant is not required to engage in the introductory discussion or preapplication review.
Any person wishing to obtain approval of a subdivision shall
submit a package meeting the following requirements to the City of
Altoona:
A. Two completed and executed original application forms.
B. A project narrative which describes the project.
C. A list of waivers being requested by the applicant, along with an
explanation as to why the applicant feels each waiver request is appropriate.
D. A copy of the recorded deed for each property included in the proposal.
If applicable, this shall include copies of all documents indicating
any easements, rights-of-way, restrictions, covenants, trusts, or
other encumbrances on the land.
E. A list of all owners of land abutting the proposal and directly across
any streets, watercourses, or railroads. For corner properties, this
shall include the land diagonally across the intersection as well.
F. Three copies of any studies that may be required by the applicable
section of this chapter or other controlling law or regulation.
G. The appropriate filing fees as established by resolution of the City
Council from time to time. Fees are due at approval.
H. If the submittal requires review by the Blair County Planning Commission,
the package shall also include the appropriate filing fee for that
review.
I. A list of all plans being submitted, with the title of the plan,
sheet number, and date on a letter-size sheet of paper.
J. Seven prints of the plan package described in Subsection
K(5) below.
K. All plans submitted shall conform to the following requirements:
(1) The sheet size shall not exceed 24 inches by 36 inches but shall
be at least 8 1/2 inches by 11 inches.
(2) The different types of plans shall be on separate sheets of paper,
all of the same size.
(3) Contact prints shall be dark line on light background.
(4) The title block shall appear in the same location on all sheets.

applicable.
All plans submitted shall depict the proposal, which shall conform
to the following basic layout standards for subdividing the land.
A. Placement of buildings:
(1) Buildings, landscaping, and screening shall be placed so that they
conceal the less desirable elements generally installed with construction
(items such as air-conditioning units, parking areas, garages, and
garbage storage are typical of such elements) so that they are not
visible from adjacent lots and streets.
(2) Building areas shall be laid out so that any scenic site features
and views are preserved, both into and out of the site.
(3) Building layout shall promote a sense of neighborhood yet allow individual
privacy for each landowner.
(4) Buildings sited in such a manner that they may block public scenic
views through the site shall be laid out and designed so as to complement
the viewshed into which they are placed. Attempts shall be made to
preserve a portion of the viewshed, whenever practical.
(5) Building sites shall be laid out with consideration given to the
provision of adequate solar access and air circulation. New development
shall be accomplished such that excessive winds are neither created
nor exacerbated.
(6) Building sites shall be laid out and graded so as to provide positive
drainage away from proposed buildings.
(7) Building placement shall not hinder the effective and efficient response
of emergency personnel in a fire or medical emergency.
(8) Buildings shall not be sited or designed to create a public nuisance
or a traffic hazard once constructed.
B. Placement of lot lines.
(1) Lots shall be laid out so as to provide buildable areas, accessible
driveways, and usable yards and open space areas, with the minimum
possible disturbance to the site.
(2) Lots shall be laid out with consideration given to views and privacy.
(3) Lots shall meet the minimum requirements of Chapter
800, Zoning. Where this is not possible or not desired, the lot shall be conspicuously labeled "unbuildable" and appropriate legal instruments restricting construction on the lot shall be executed with the City as party.
(4) Lots shall abut on public streets (including new streets intended
to be public).
(5) Lots should be laid out to avoid driveway access from roadways with
three or more lanes. Twin one-way pairs shall be considered as one
roadway for purposes of this standard.
(6) Lot shape shall be rectangular wherever practical. Where not practical,
other shapes may be proposed so long as side lot lines intersect the
street right-of-way line at no more than 45° from perpendicular
or radial and maintain the intersecting angle until such side line
intersects a projected line running parallel to and 20 feet away from
the street right-of-way line.
C. Layout of blocks.
(1) Block length shall be a minimum of 300 feet and no longer than 800
feet.
(2) Blocks in residential areas shall be of sufficient depth to allow
for two house lots between avenues.
(3) Alleys are neither required nor prohibited.
(4) Block layout shall be designed giving neighborhood stability and
nonautomotive traffic primacy above automotive traffic and parking.
All subdivision proposals shall provide for the following environmental
mitigation measures as well as any additional requirements of the
state and federal governments.
A. Grading and soil removal.
(1) It is the intent of this subsection to protect life and property
by preventing rock and soil slippage, loss and degradation of natural
drainageways, increased soil erosion and sedimentation, and other
soil and water management issues.
(2) Grading shall be limited to the minimum area necessary to provide
for buildings, roads, parking areas, utilities, and other facilities
shown on the subdivision plan.
(3) A soil erosion and sedimentation plan shall be prepared in accordance with Chapter
580 and Chapter
620.
(4) Where required by the National Pollution Discharge Elimination System
or state regulations, a permit shall be secured prior to the commencement
of any grading or earthmoving activities for the following:
(a)
Development of sites between five and 25 acres in size which
are not located within a special protection watershed and which are
not ineligible for other reasons specified in the Pennsylvania Department
of Environmental Protection regulations. In this case, General Permit
PAG-2 may be used once obtained from the Blair County Conservation
District.
(b)
Development of sites in excess of 25 acres in size that are
not divided into parcels shall obtain individual NPDES permits. Individual
NPDES permits are also required for smaller sites that are located
in special protection watersheds or are otherwise ineligible for the
general permit. Processing of individual NPDES permits has been delegated
to the Blair County Conservation District.
(5) The applicant is responsible for protecting adjacent and downstream
properties from any damage which occurs as a result of earth disturbance
on the development site. Such protection shall include cleaning up
and restoring to their predamage condition any adjacent or downstream
properties adversely affected by silt, debris, flooding, or other
damage resulting from the earth disturbance activity.
(6) The top and bottom edges of cut-and-fill slopes shall be set back
from property lines a minimum of two feet plus 20% of the height of
the slope. This setback need not exceed 10 feet.
(7) Topsoil stripped from the site in preparation for earthmoving activities
shall be stockpiled and replaced on the site over all regraded nondeveloped
areas at a minimum depth of six inches.
(8) Fill areas shall be prepared by removing organic material such as
vegetation or rubbish and any other material which is determined to
prevent proper compaction and stability.
(9) Proposed grading activities shall be accomplished so that post-development stormwater flows cause no additional harm to abutting properties and streets. The stormwater management provisions of Chapter
620 apply.
(10)
Maximum gradient of graded slopes shall be no greater than two
horizontal feet to one vertical foot, except as follows:
(a)
Where the height of a proposed slope will not exceed 10 feet,
then a maximum gradient of 1:1 may be permitted where soil conditions
permit and where doing so will help preserve existing vegetation or
other significant natural features.
(b)
Where a retaining wall, designed and sealed by a registered
professional engineer, is constructed to support the face of the slope.
(11)
Excavation adjacent to any building foundation walls, footings,
or structures shall not extend beyond the angle of repose or natural
slope of the soil under the nearest point of same unless the footings,
foundations, or structures have been sufficiently underpinned or otherwise
protected against settlement.
B. Steep slopes. The following shall apply to all grading and disturbance
on land with slopes of 25% or greater.
(1) For slopes between 25% and 40%, no more than 30% of the slope area
shall be stripped of vegetation or disturbed through grading. Grading
and clearing for roads on these slopes shall be limited to that necessary
to accommodate the improvements required by this chapter. Wherever
possible, roads should follow the contours of the land.
(2) No development or disturbance shall be allowed on slopes exceeding
40%. Limited disturbance for utilities may be allowed where no reasonable
alternative location exists.
C. Significant natural areas and features.
(1) Where a proposed subdivision includes an identified natural area
or feature such as endangered species or wetlands, the applicant shall
demonstrate compliance with all applicable state and federal requirements.
(2) All healthy trees with trunks equal to or exceeding 24 inches in
diameter, or any tree which may be noteworthy because of its species,
age, uniqueness, rarity, or status as a landmark due to historical
or other cultural association, shall be preserved, unless removal
is deemed necessary by these criteria:
(a)
The health of the tree is such that it is dead, dying, or diseased
beyond remedy.
(b)
The tree endangers the public or adjoining property.
(c)
Site constraints make preserving the tree impossible.
(3) Large trees removed pursuant to Subsection
C(2) above shall be replaced with a minimum of three trees with a minimum caliper of three inches. Tree placement shall be in such a manner so as to complement the site and ensure the long-term health of the trees planted.
D. Water quality.
(1) All buildable lots within the subdivision shall be supplied public sewage facilities. The applicant must document application for a sewage facilities planning module prior to approval under Chapter
580. Approval from the Department of Environmental Protection must be obtained prior to the issuance of a building permit. A note stating that such approval must be obtained prior to the issuance of a building permit must appear on the plan.
(2) The applicant shall provide public access to any watercourses located
within the project area. This may be done by street, sidewalk, walkway,
or bikeway.
(3) The applicant is responsible for compliance with any state or federal
requirements that may apply to the project when the project is located
within 50 feet of a waterway or regulatory wetland.
E. Air quality. Design of the subdivision should promote alternative
modes of transportation to reduce automotive dependency. Transit-oriented
design is encouraged to promote air quality.
F. Noise. Subdivisions located in areas which are subject to high levels
of noise may install soundproofing measures to mitigate the noise.
In all cases, a notation shall be made on the plan that the project
is subject to high levels of noise.
It is the intent of the City that all newly proposed subdivisions
provide for the basic transportation needs of an urban area as well
as mitigate the effects of these provisions. These standards herein
ensure safe and convenient access to and from the site by pedestrians,
cyclists, mass transit, and the automobile.
A. General access. New subdivisions must have adequate access. To provide
for adequate access, the proponent shall ensure the following:
(1) All traffic shall be provided access to the public street system.
(2) Proposed connections to the existing street system shall be approved
by the jurisdiction owning the street at the point of connection.
(3) Where a proposed street must continue into an adjoining municipality,
the proponent shall coordinate the street design to maintain traffic
safety.
(4) Streets shall provide convenient connections and not adversely affect
the quality of life in the neighborhood.
(5) Residential streets shall be designed to minimize through traffic,
discourage excessive speeds, and provide privacy in residential areas.
B. Classifications and levels of service.
(1) Streets shall be classified as either residential or nonresidential
and shall be further classified as arterial, collector, feeder, or
local, as defined herein.
(2) The classification of each street shall be based upon the projection
of traffic volumes 10 years after the completion of the final phase
of the proposal. Traffic volumes shall be calculated in accordance
with trip generation rates published in the Trip Generation Manual
published by the Institute of Transportation Engineers (or an alternate
source acceptable to the Commission), and shall consider all traffic
likely to use that street.
(3) Each street shall be designed for its entire length to meet the standards
for its classification.
(4) Proposed streets shall be designed to function at Level of Service
B or higher. Existing streets shall not fall below Level of Service
D, unless the existing condition is worse.
(5) Private streets shall not be allowed, except in cases where a homeowners'
association is established and agreements executed placing full responsibility
for street installation, maintenance, replacement, and liability with
the homeowners' association.
C. Traffic impact study.
(1) A traffic impact study shall be required for a subdivision which
will generate more than 100 peak hour trips when fully developed.
The Commission may also require a study to assess the impacts of smaller
projects if traffic congestion or safety concerns already exist.
(2) The traffic study shall be conducted in accordance with the recommended
practice "Traffic Access and Impact Studies for Site Development,"
published by the Institute of Transportation Engineers (or an alternate
source acceptable to the Commission).
(3) The scope of the study, study area, and methodology shall be approved
by the Commission before the study is initiated. A preapplication
conference should be scheduled for this purpose.
(4) The study shall be performed by or under the supervision of a professional
engineer with training in traffic and transportation engineering studies
and experience in the preparation of traffic studies.
(5) The traffic study must yield the following results:
(a)
Demonstrate that the levels of service required in Subsection
B above will be met by the proposed subdivision and that the street layout will function safely and efficiently.
(b)
Describe any measures which have been incorporated into the
development plan in order to achieve the required conditions. Such
measures may include, but are not limited to, the following:
[1]
Traffic reduction efforts such as clustering of buildings, transit-friendly
development, or a location which would allow easy access of pedestrians
and bicyclists to other land uses thereby reducing reliance on the
automobile.
[2]
Phasing of construction to coincide with the completion of transportation
improvements programmed by the public sector.
[3]
Construction of on-site transportation improvements.
[4]
Construction of off-site transportation improvements.

(a)
All dead-end streets over 50 feet in length shall be provided
with a turnaround on the closed end.
(b)
Turnarounds shall be centered on the approaching street or offset
to the left of the approaching street.
(c)
A turnaround shall end in a cul-de-sac with a paved cartway
of 12 feet, with a minimum outer radius of 70 feet, surrounding a
landscaped island, except in the following cases:
[1]
A teardrop-style cul-de-sac may be used in an area where longer
vehicles are expected to make up a significant proportion of the traffic
volume. If used, the engineer shall demonstrate that the pavement
width(s) and radii used will serve the traffic and neighborhood well.
[2]
On residential streets serving fewer than five units, a hammerhead
may be installed if insufficient space exists for a cul-de-sac. The
legs of the hammerhead shall extend at least 50 feet, and the width
shall be consistent with that of the approaching street.
[3]
Temporary turnarounds shall be installed at the ends of streets
which are to be extended within 10 years. Temporary turnarounds shall
be designed to the minimum standard necessary to handle projected
traffic flow while the temporary treatment is in place. A cul-de-sac,
bumpout, hammerhead, "T" or "Y" may be used in these cases.
(d)
Dead-end streets shall be posted with a "no outlet" sign, or
approved equivalent, at the entrance to the street.

For all streets except arterial roads, the curb radii at an
intersection shall be 25 feet. For any intersection involving arterial
roads, the curb radii shall be 50 feet.
(i)
Intersections on arterials shall not cut across the medial strip
unless the intersection is signalized.
(6) Traffic calming.
(a)
Traffic-calming measures may be required to mitigate the effect
of subdivisions that could create a cut-through for traffic, allow
traffic at moderate to high rates of speed, or create hazardous conditions
for pedestrian traffic.
(b)
Such traffic-calming measures shall be appropriate to the situation
and shall be the minimum necessary to mitigate the effects of vehicular
traffic on the neighborhood.
(c)
Measures to be considered for cut-through traffic include traffic
circles, intersection tables, one-way flows, bump-outs, and on-street
parking.
(d)
Measures to be considered for traffic moving at moderate to
high speed include speed humps, intersection tables, on-street parking,
and traffic circles (both at intersections and mid-block), and median
islands.
(e)
Measures to be considered for pedestrian hazards include refuge
islands, sidewalks, intersection tables, crossing flags, signals,
and bump-outs.
(f)
The above listings are not to be considered exhaustive; if an
unlisted measure is deemed appropriate, it may be substituted.
(g)
All traffic-calming measures shall be installed in accordance
with traffic-calming device standards promulgated by the Pennsylvania
Department of Transportation.
(7) Curbs.
(a)
Vertical or sloped curbs shall be required along both sides
of all streets, along both sides of all median strips, and along the
full perimeter of all cul-de-sac islands. Curbs shall be granite or
concrete; asphalt curbs are not acceptable.
(b)
A maximum of one fourteen-foot curb cut shall be provided each
lot in the subdivision. As Altoona is an urban setting, on-street
parking, neighborhood parking or alley access are preferred over driveway
cuts.
(c)
Curbing shall be vertical for a distance of two feet on both
sides of all catch basins. Where a swale system is used, drainage
cuts in the curbing shall consist of sloped curb.
(8) Shoulders and embankments.
(a)
The area between the curbing and the sidewalk (or right-of-way
line, where no sidewalk is required) shall be constructed so as to
support a vehicle should one leave the pavement area or need to pull
to the far right to park safely.
[1]
The area between the curb and the sidewalk shall be prepared
with a twelve-inch gravel base and a three-inch surface mixture of
2/3 gravel and 1/3 loam.
[2]
This area shall be graded with a horizontal pitch of 3/8 inch
per foot.
[3]
This area shall be seeded with a fine-bladed lawn grass.
[4]
The plan should make attempts to keep two feet closest to the
curb free of all obstacles, especially in areas where sloped curb
is used.
(b)
Embankments shall be graded so as to blend in with existing
topography. Newly created embankments shall be stabilized with vegetation
to prevent erosion or movement.
(c)
Retaining walls in the street right-of-way shall be avoided
in residential areas unless such an installation is the only practical
way to install the roadway. When used, retaining walls shall be designed
to complement the residential nature of the proposal.
(9) Lights and traffic control devices.
(a)
Streetlighting shall be required for all subdivisions, as follows:
[1]
In residential areas (except arterials), lighting shall be provided
at every intersection.
[2]
In nonresidential areas (except arterials), lighting shall be
provided so as to light up the entire street right-of-way independently
of any other lighting that may be present. Intersection lighting shall
be wired separately so that the City may lower the mid-block lighting
during nonbusiness hours.
[3]
For arterials, lighting shall be placed in the median at sufficient
distance so as to provide light to the entire street. Lighting at
signalized intersections may be placed on the shoulders.
(b)
The placement and design of light standards shall provide adequate
lighting to the street right-of-way without posing a hazard to drivers
or a nuisance to abutting properties.
(c)
Streetlighting units shall be no higher than 20 feet above grade
and shall be designed to direct light downward onto the street.
(d)
Street name signs shall be provided at all new intersections
and shall be of the standard size and placed for maximum visibility.
(e)
Traffic control signs and other control devices shall be provided
by the applicant as needed. The applicant shall use the Manual on
Uniform Traffic Control Devices for Streets and Highways, Millennial
Edition, for guidance; however, the use of signs shall be minimized.
(10)
Street trees.
(a)
Trees shall be required along both sides of all roadways and
spaced not more than 50 feet apart. The goal is to provide a complete
canopy over the street right-of-way.
(b)
Trees shall be located no closer than two feet to the curb.
(c)
Trees to be planted shall have a minimum diameter of two inches
at a point four feet above the ground. All stock shall be nursery-grown,
balled, and burlapped.
(d)
In order to protect against the potential for all of the street
trees in any neighborhood to be lost to disease or insects, no more
than 1/3 of the trees planted shall be of the same species.
(e)
Tree grates or fencing may be required to protect new trees
in dense areas or other high-traffic areas.
(f)
Trees shall be planted in the following manner:
[1]
Each tree to be planted shall be placed in a hole dug one foot
wider and one foot deeper than any part of the root ball.
[2]
Soil to be replaced around the root ball is to be a good quality
loam.
[3]
The root ball shall be placed two inches deeper than the surrounding
undisturbed soil to create a depression that holds water.
[4]
Each tree shall be watered immediately after planting to settle
the soil and moisten the roots.
[5]
Trees shall have temporary labels attached so inspectors can
determine compliance with the approved plan.
(g)
The developer is responsible to guarantee all planted trees
live through one complete growing season.
E. Driveways.
(1) All driveways shall enter streets at safe locations. No driveway
shall enter a public street within 50 feet of an intersection.
(2) Shared driveways for up to four houses are permitted. Shared driveways
shall have a minimum width of 10 feet, be set within a twenty-foot
easement, and shall be subject to a maintenance agreement entered
into by the owners of the lots served by the driveway. Shared driveways
shall be permitted only where the physical constraints of the project
do not allow proper individual access points for each individual property.
(3) Reasonable sight distance shall be provided all driveways.
F. Transit facilities. Where a proposed subdivision is to be located
along or within reasonable walking distance of an existing or proposed
transit route, the developer shall provide the bus shelters and provide
any pull-offs for transit vehicles at bus stops, as determined by
the Commission in consultation with the transit authority.
G. Bicycle facilities.
(1) All new streets shall be planned and constructed to safely accommodate
bicycle traffic.
(2) Where a subdivision is to be located along or within 1/2 mile of
an existing bikeway or a bikeway proposed by the city, county, region
or state, the subdivision plan shall include connections to the bicycle
facility in accordance with the Policy on Geometric Design of Highways
and Streets, 1994 edition, published by AASHTO.
(3) Bicycle facilities shall be included within the street right-of-way
where practical. The developer may propose off-street bikeways, provided
these are eight-feet-wide within a sixteen-foot-wide easement providing
full public access to the bikeway. Such facilities shall conform to
standards published in the Policy on Geometric Design of Highways
and Streets, 1994 edition, published by AASHTO.
H. Pedestrian facilities.
(1) Sidewalks which exist within the street right-of-way and run generally
parallel to the street shall meet the following standards:
(a)
Sidewalks shall be provided in every subdivision.
(b)
Sidewalks shall be parallel to the street and located so that
the outer edge of the sidewalk runs coincident with the street right-of-way
line.
(c)
Sidewalks shall be set back at least four feet from the curbline
in residential areas. In commercial areas, with the exception of Business
Route 220, the sidewalk width shall be extended to the curb to accommodate
the commercial activity. Along Business Route 220, the sidewalk shall
be set back from the curbline as in residential areas.
(d)
Sidewalks shall be a minimum of four feet wide. If the sidewalk
is to double for bicycle use, the sidewalk shall be eight feet wide.
(e)
Sidewalks shall be constructed with concrete.
(2) Pathways which exist outside the street right-of-way but are available
for general use shall meet the following standards:
(a)
Pathways shall be installed to connect major use areas, two
portions of the same neighborhood, two dead-end streets, or stream
crossings. Pathways shall also be installed to provide access to public
amenities such as streams, parks, precipices, cemeteries, and so forth.
(b)
A pathway shall be available for both pedestrian and bicycle
use but shall be designed to prevent use by motorized vehicles.
(c)
Pathways shall be at least six feet wide within a twelve-foot
easement providing full public access.
(d)
Pathways shall be constructed of a permanent nonerosive material
conducive to use by pedestrians and bicycles.
(e)
Pathways shall be named and clearly labeled as public ways.
(3) All pedestrian facilities shall provide appropriate wheelchair access
where they intersect the street system. All facilities shall be constructed
in accordance with federal standards for handicapped accessibility.
(4) All pedestrian facilities shall be designed to foster a sense of
neighborhood and promote neighborly interaction without posing danger
to pedestrians and residents of the neighborhood.
I. Common parking. In commercial areas and high-density neighborhoods,
the Commission may require installation of a common parking facility
to help alleviate future parking shortages. This may require a set-aside
of land within the subdivision or a redesign of the street to accommodate
additional on-street parking (i.e., angled parking).
