This section should refer to compliance with §
250-33 and the stormwater ordinance requirements.
A. The owner shall construct stormwater drainage facilities, including
curbs, catch basins and inlets, storm sewers, culverts, road ditches,
open channels, swales, concrete headwalls, low-flow channels, erosion
protection, detention and retention basins and other structures in
order to prevent erosion, flooding and other hazards to life and property.
All such facilities are to be of adequate size and grade to hydraulically
accommodate maximum potential volumes of flow, and size, type and
installation of all storm drains and sewers shall be constructed in
accordance with the approved plans.
B. Calculations of drainage areas, rainfall intensity based on design
of storm frequencies and co-efficiency of rainfall runoff shall be
in accordance with the provisions of the Hatfield Township Stormwater
Management and Grading Ordinance, as amended, and shall be submitted to the Township Engineer
for his review and approval or disapproval.
[Amended 12-19-2012 by Ord. No. 640]
C. All storm drainage facilities shall be constructed of reinforced
concrete pipe unless alternate construction is approved by the Hatfield
Township Commissioners considering the advice of the Township Engineer.
All required planting shall be done in accordance with §
250-38 of this chapter and the following:
A. All landscape improvements shall be installed and be maintained by
accepted practices as recognized by the American Society of Landscape
Architects and/or American Association of Nurseryman's Standards.
Planting and maintenance of vegetation shall include, but not be limited
to, provision for mulch, guy wires and stakes, fertilization, watering,
insect control, disease control and pruning.
B. The applicant shall make arrangements acceptable to the Township
that all landscape improvements installed in accordance with this
chapter shall be maintained in a healthy and/or sound condition, or
otherwise be replaced by equivalent improvements, for a period of
at least 18 months following their installation, except as otherwise
required by this chapter.
C. The applicant shall make arrangements acceptable to the Township
for the property's long-term landscape maintenance. The applicant
shall provide the names, addresses, and telephone numbers of those
persons or organizations which will be assuming such responsibilities.
In the event that any improvements which may be required have
not been installed as provided in this chapter or in accord with the
approved final plat, the Board of Commissioners is hereby granted
the power to enforce any corporate bond or other security by appropriate
legal and equitable remedies. If the proceeds of such bond or other
security are insufficient to pay the cost of installing or making
repairs or corrections to all the improvements covered by said security,
the Board of Commissioners may, at its option, install part of such
improvements in all or part of the subdivision or land development
and may institute appropriate legal or equitable action to recover
the moneys necessary to complete the remainder of the improvements.
All of the proceeds, whether resulting from the security or from any
legal or equitable action brought against the developer, or both,
shall be used solely for the installation of the improvements covered
by such security, and not for any other Township purpose.
