This chapter shall be known and may be cited as the "The City of Lancaster Stormwater Management (SWM) Ordinance."
The Lancaster City Council finds that:
A. 
Inadequate management of accelerated stormwater runoff resulting from development throughout a watershed increases flood flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of existing streams and storm sewers, greatly increases the cost of public facilities to convey and manage stormwater, undermines floodplain management and flood reduction efforts in upstream and downstream communities, reduces groundwater recharge, and threatens public health and safety.
B. 
A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated erosion, is fundamental to the public health, safety, welfare, and the protection of the people of the City of Lancaster and all the people of the commonwealth, their resources, and the environment.
C. 
Stormwater is an important water resource, which provides groundwater recharge for water supplies and base flow for healthy streams, which also protects and maintains surface water quality.
D. 
The use of green infrastructure and low-impact development (LID) are intended to address the root cause of water quality impairment by using systems and practices which use or mimic natural processes to: 1) infiltrate and recharge, 2) evapotranspire, and/or 3) harvest and use precipitation near where it falls to earth. Green infrastructure practices and LID contribute to the restoration or maintenance of predevelopment hydrology.
E. 
Federal and state regulations require certain cities to implement a program of stormwater controls. These cities are required to obtain a permit for stormwater discharges from their Municipal Separate Storm Sewer Systems (MS4) under the National Pollutant Discharge Elimination System (NPDES).
F. 
Riparian forest buffers enhance water quality by filtering pollutants in runoff, providing light control and temperature moderation, processing pollutants, increasing infiltration and providing channel and shoreline stability thus decreasing erosion (DEP Riparian Forest Buffer Guidance, November 27, 2010).
G. 
Much of the City is served by a combined sewer system that collects and transports both domestic sewage and rainwater that flows from impervious surfaces such as roofs, streets, and parking lots. The City's Advanced Wastewater Treatment Facility is normally able to manage and clean the volume of wastewater flowing through the combined sewer system; however, during intense rainstorms and other wet weather events, the system becomes overwhelmed causing untreated combined sewage to overflow into the Conestoga River. These events are referred to as combined sewer overflows.
The purpose of this chapter is to promote health, safety, and welfare within the City of Lancaster by minimizing the damages described in § 260-102 of this chapter through provisions designed to:
A. 
Manage accelerated runoff and erosion and sedimentation problems at their source by regulating activities that cause these problems.
B. 
Utilize and preserve the existing natural drainage systems.
C. 
Encourage recharge of groundwater where appropriate and prevent degradation of groundwater quality.
D. 
Maintain existing flows and quality of streams, watercourses and water conveyance facilities in the City of Lancaster and the commonwealth.
E. 
Preserve and restore the flood-carrying capacity of streams and associated floodplains.
F. 
Provide proper operation and maintenance of all stormwater management best management practices (SWM BMPs) that are implemented within the City.
G. 
Provide performance standards and design criteria for watershed-wide stormwater management and planning.
H. 
Meet or exceed, in light of unique local conditions, legal water quality requirements under state law, including regulations at 25 Pa. Code Chapter 93 to protect, maintain, reclaim, and restore the existing and designated uses of the waters of the commonwealth.
I. 
Prevent scour and erosion of stream banks and streambeds.
J. 
Provide standards to meet NPDES permit requirements.
K. 
Help preserve and protect exceptional natural resources, and conserve and restore natural resource systems.
L. 
Promote stormwater management practices that emphasize infiltration, evaporation, and transpiration.
M. 
Reduce combined sewer overflows.
A.

Any work undertaken or use established pursuant to such permit or other authorization is unlawful and shall be enforced in accordance with Article IX, Enforcement and Penalties. No action may be taken by a board, agency or employee of the City purporting to validate such a violation.
Except as specifically provided by the Pennsylvania Storm Water Management Act, Act of October 4, 1978, P.L. 864, No. 167, as amended, 32 P.S. § 680.1 et seq., the making of any administrative decision by the City of Lancaster or any of its officials or employees shall not constitute a representation, guarantee or warranty of any kind by the City of Lancaster of the practicability or safety of any proposed structure or use with respect to damage from erosion, sedimentation, stormwater runoff, flood, or any other matter, and shall create no liability upon or give rise to any cause of action against the City of Lancaster and its officials and employees. The City of Lancaster, by enacting and amending this chapter, does not waive or limit any immunity granted to the City of Lancaster and its officials and employees by the Governmental Immunity Act, 42 Pa.C.S.A. § 8541 et seq., and does not assume any liabilities or obligations.
Notwithstanding any provision(s) of this chapter, including exemptions, any landowner or any person engaged in the alteration or development of land which may affect stormwater runoff characteristics shall implement such measures as are reasonably necessary to prevent injury to health, safety, or other property. Such measures also shall include actions as are required to manage the rate, volume, direction, and quality of resulting stormwater runoff in a manner which otherwise adequately protects health, safety and welfare.
A. 
A financial security (bond, restricted escrow or letter of credit) for stormwater-related improvements shall be supplied by the applicant in conjunction with any subdivision/land development approval, or in conjunction with the SWM site plan approval if no subdivision/land development plan is required, except very small projects, as defined in this chapter, shall be exempt from this requirement.
B. 
The applicant shall provide a financial security to the City of Lancaster for the timely installation and proper construction of all SWM facilities except for very small projects, as defined herein, including E&S BMPS, as required by the approved SWM site plan and this chapter and, as applicable, in accordance with the provisions of Sections 509, 510, and 511 of the MPC.[1]
[1]
Editor's Note: See 53 P.S. §§ 10509, 10510, and 10511.
C. 
As the work of installing the required SWM facilities proceeds, the party posting the financial security may request the City of Lancaster to release or authorize the release, from time to time, such portions of the financial security necessary for payment to the contractor or contractors performing the work. Any such requests shall be in writing addressed to the City of Lancaster, and the City of Lancaster shall have 45 days from receipt of such request within which to allow the Director to certify, in writing, to the City of Lancaster that such portion of the work upon the SWM facilities has been completed in accordance with the approved SWM site plan. Upon such certification the City of Lancaster shall authorize release by the bonding company or lending institution of an amount as estimated by the Director fairly representing the value of the SWM facilities completed. The City of Lancaster may, prior to final release at the time of completion and certification by its Director, require retention of not more than 15% of the estimated cost of the aforesaid SWM facilities for 18 months.
D. 
In the event that any SWM facilities which may be required have not been installed as provided in the approved SWM site plan, the City of Lancaster is hereby granted the power to enforce any corporate bond, or other security by appropriate legal and equitable remedies. If proceeds of such bond or other security are insufficient to pay the cost of installing or making repairs or corrections to all the SWM facilities covered by said security, the City of Lancaster may, at its option, install part of such SWM facilities and may institute appropriate legal or equitable action to recover the monies necessary to complete the remainder of the SWM facilities. All of the proceeds, whether resulting from the security or from any legal or equitable action brought against the applicant, or both, shall be used solely for the installation of the SWM facilities covered by such security, and not for any other City purpose.
