[Ord. 158, 12/20/1994, § 401]
1. Purpose. A sketch plan is an optional submission. It is offered to
give the applicant an opportunity to consult early and informally
in the plan preparation phase with the Township and Bucks County Planning
Commission. The purpose of this submission is to allow the Township
and the applicant opportunity to discuss lot layout, street layout,
location of buildings, arrangement and location of open space, etc.,
before detailed engineering is done. The Township may comment on not
only whether the sketch plan meets the objectives of Township ordinances
but, also if they feel it is consistent with sound planning and design
principles. It is not intended in any way to replace the preliminary
plan, but rather to give the applicant guidance in preparing the much
more detailed preliminary plan. Recommendations and comments made
by the Township in response to sketch plan submission shall in no
way be regarded as an official approval, nor shall such action grant
any legal rights to the applicant or immunity from full compliance
with requirements and procedures set forth for preliminary and final
plans.
2. Data furnished in a sketch plan shall be at the discretion of the
subdivider but is suggested to include the following:

1. Purpose. The traffic impact study will enable East Rockhill Township
to assess the impact of the proposed development on the transportation
system, highways, public transportation and pedestrian/bicycle trails
in the Township. The purpose of the impact study is to ensure that
proposed developments do not adversely affect the transportation network
and to identify any traffic problems associated with access between
the site and the existing transportation network as well as to recommend
necessary improvements that will mitigate deficient traffic operations.
The study's purpose is also to delineate solutions to potential problems
and to present improvements to be incorporated into the proposed development.
The study shall assist in the protection of air quality, conservation
of energy and encouragement of public transportation use.
2. The traffic impact study shall be prepared by a qualified traffic
engineer and/or transportation planner with previous traffic study
experience. Procedures and standards for the traffic impact study
are set forth herein. The applicant may provide funds to the Township,
which may hire a traffic engineer of its choice to conduct the study,
if deemed appropriate by the Township.
3. Applicability.
A. A traffic impact study shall be submitted for all residential subdivisions
or land developments of 25 or more residential lots and/or dwelling
units; all commercial, office, industrial, institutional or other
nonresidential uses requiring subdivision or land development approval;
all rezoning requests; and/or any other project when deemed necessary
by the Board of Supervisors.
B. The East Rockhill Township Board of Supervisors, at its discretion,
may require any other subdivision or land development application
to be accompanied by a traffic impact study; provided, however, that
the Supervisors notify the applicant within 60 days following the
Planning Commission's first meeting to consider the proposal. Such
notification shall specify the reason for the requirement, citing
the proposal's particular location or existing problems or type of
use (e.g., generation of heavy truck traffic).
