Editor's Note: This local law also repealed former Ch. 228, Stormwater Management, adopted 9-11-2006 by L.L. No. 10-2006.
This chapter shall be known as the "Stormwater Management and Erosion and Sediment Control Law."
The Town Board of the Town of Ithaca finds the following:
A. 
Land development activities and increases in site impervious cover permanently alter the hydrologic responses of local watersheds and increase stormwater runoff rates and volumes, which in turn increase flooding, stream channel erosion and sediment transport and deposition, and decrease groundwater recharge.
B. 
Stormwater runoff from developed areas contributes significant quantities of waterborne pollutants to surface and groundwater sources, degrading water bodies, affecting public and private water supplies, recreational uses, and threatening fish and other aquatic life.
C. 
The clearing and loss of vegetation, and the grading of the soil for development purposes, particularly on moderate to steep slopes, can increase soil erosion, leading to siltation of water bodies, decreasing their capacity to hold and transport water, and degrading terrestrial and aquatic habitats.
D. 
Impervious surfaces and regraded land surfaces associated with development reduce the infiltration of rainfall into the soil and the recharge of groundwater resources.
E. 
Improper design, construction, and implementation of stormwater and erosion control facilities and practices can also increase stormwater runoff rates and volumes, leading to increased flooding, stream channel erosion, sediment transport and deposition and overall degradation to water bodies.
F. 
Substantial economic losses can result from these adverse impacts to the community waters.
G. 
The southern end of Cayuga Lake, which includes that portion in the Town of Ithaca, and which ultimately receives drainage water from land area in the Town, has been placed on the New York State 2004 Section 303(d) List of Impaired Waters. This list identifies sediment/silt and phosphorus as the major sources contributing to this impairment.
H. 
Stormwater runoff, soil erosion, and nonpoint source pollution can be controlled and minimized through the regulation of stormwater runoff quantity and quality from new land development and redevelopment activities, through the use of both structural and nonstructural practices.
I. 
It is in the public interest, and will minimize threats to the environment and to public health and safety, to regulate stormwater runoff from land development activities within the Town of Ithaca as provided in this chapter in order to control and minimize increases in stormwater runoff rates and volumes, to provide for the recharge of groundwater resources, and to control and minimize soil erosion, stream channel erosion, and nonpoint source pollution associated with land development activities.
J. 
Town regulation of land development activities by means of establishing performance standards governing stormwater management and site design will act to mitigate the adverse effects associated with stormwater runoff, erosion and sedimentation from development.
The purpose of this chapter is to establish minimum stormwater management requirements and controls to protect, maintain and enhance the health, safety, and general welfare of the citizens of the Town and its natural environment, to protect and preserve the property of the Town and of its residents, and to address the findings stated above in § 228-2, by achieving the following objectives:
A. 
Meet the requirements of minimum measures 4 and 5 of the New York State Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Municipal Separate Stormwater Sewer Systems (MS4s), Permit No. GP-02-02, as it may be amended from time to time, which permit applies to the Town.
B. 
Require land development activities to conform to the substantive requirements of the New York State SPDES General Permit for Construction Activities Permit No. GP-02-01, as it may be amended from time to time.
C. 
Control and reduce stormwater runoff rates and volumes, in order to reduce or minimize flooding, stream channel erosion, property damage, and to maintain the integrity of stream channels and aquatic habitats.
D. 
Control and minimize soil erosion from land development activities and prevent the transport of sediment to receiving water bodies.
E. 
Facilitate removal of pollutants in stormwater runoff so as not to degrade ground and surface water quality.
F. 
Protect the biological, ecological, and other beneficial functions of water bodies, such as streams, wetlands, lakes and reservoirs, from the adverse impacts of stormwater runoff.
G. 
Encourage groundwater recharge so as to maintain stream base flows, aquatic life, and adequate water supplies.
H. 
Establish provisions for the long-term responsibility for and maintenance of stormwater control facilities and practices to ensure that they continue to function as designed, are maintained, and pose no threat to public safety.
I. 
Establish provisions to ensure there are adequate funding mechanisms, including financial security or surety, for the proper review, inspection and long-term maintenance of stormwater facilities and practices implemented pursuant to this chapter.
J. 
Establish provisions for the Town to recover all costs and expenses incurred by the Town for any repairs it makes to stormwater management practices.
K. 
Establish administrative procedures for the submission, review, approval or disapproval of stormwater management plans, and for the inspection of approved active development projects, and long-term oversight of the stormwater control facilities and practices.
This chapter is adopted pursuant to the laws of the State of New York, including § 130, Subdivision 15, of the Town Law, § 10, Subdivision 1(ii)(a)(9-a), (11) and (12) of the Municipal Home Rule Law, and § 10, Subdivision 2 of the Municipal Home Rule Law.

A. 
The Town Board designates the Town Engineer as the Stormwater Management Officer for the purposes of this chapter.
B. 
The Planning Department will receive all stormwater pollution prevention plans that are subject to review and approval by the Town of Ithaca Planning Board or Zoning Board of Appeals, and forward such plans to the Town Engineer for review and a determination of whether the SWPPP complies with the requirements of this chapter.
C. 
Applicants for all land development activities not subject to review and approval by the Town of Ithaca Planning Board or Zoning Board of Appeals shall be required to submit any required SWPPP or erosion and sedimentation control plan to the Stormwater Management Officer, or his or her designee, who shall have responsibility for reviewing and approving the plan if it is determined to comply with the requirements of this chapter.
D. 
Nothing in this chapter supersedes an applicant's obligation to obtain permit coverage from the New York State Department of Environmental Conservation, as described in the SPDES General Permit for Stormwater Discharges from Construction Activity (GP-02-01). For activities that require full or basic SWPPPs, the applicant must also submit a notice of intent and SWPPP to the New York State Department of Environmental Conservation. The applicant shall also send a copy of the notice of intent and notice of termination to the Town.
A. 
Technical standards.
(1) 
All full and basic SWPPPs and simple erosion and sedimentation control plans shall contain appropriate stormwater management practices that are designed and constructed in accordance with the standards set forth in the Design Manual and Erosion Control Manual.
(2) 
The use and implementation of stormwater credits. The New York State Department of Environmental Conservation has identified nonstructural stormwater management practices which qualify as stormwater credits that can reduce the water quality treatment volume and the water quantity/stream channel protection volume required for projects requiring a full SWPPP. Such nonstructural stormwater management practices are described in the DEC document entitled "The Use and Implementation of Stormwater Credits." The Town encourages the use of such nonstructural stormwater management practices to minimize reliance on structural stormwater management measures, and the Town will allow the applicant to utilize stormwater credits if the following requirements are met:
(a) 
These practices must be reviewed and approved by the Town of Ithaca before the credit can be taken.
(b) 
These practices must be implemented as described in "The Use and Implementation of Stormwater Credits" document, as it may be revised from time to time, or as described in any successor document issued by DEC.
B. 
Better site design requirements for full SWPPPs. For projects requiring a full SWPPP, stormwater management objectives must also incorporate nonstructural stormwater management practices into the project design as specified below. The New York State Department of Environmental Conservation has identified a set of "better site design practices" (several of which overlap with the stormwater credits above), which can reduce the impacts of a project, and also often reduce costs. Many of these practices will result in smaller required stormwater treatment and storage volumes.
(1) 
Projects requiring a full SWPPP must apply a minimum of two of these techniques/practices.
(2) 
If the applicant contends that the minimum number of practices cannot be incorporated into the project design due to site limitations, the applicant must explain and justify such limitations to the satisfaction of the Board responsible for project review and approval.
C. 
Water quality standards. All land development activities must comply with New York State water quality standards, whether or not a project is subject to this chapter. These standards are enforceable by the New York State Department of Environmental Conservation and include the following prohibitions:
(1) 
Any land development activity shall not cause an increase in turbidity that will result in substantial visible contrast to natural conditions in surface waters of the State of New York.
(2) 
Any land development activity shall not cause a flow alteration that will impair surface waters of the State of New York for their best usages.
D. 
General standards.
(1) 
Developers and landowners must avoid and minimize disturbance of wetlands, stream corridors, and surface waters to the maximum extent practicable at the project site, and obtain the relevant state or federal permits if a disturbance will take place. Land development activities shall not discharge untreated stormwater directly into a natural wetland or water body without adequate treatment, nor modify natural wetlands for stormwater impoundment. To the extent possible, a buffer must be maintained between land development activities (including the placement of silt fencing) and wetland boundaries, stream banks, or lake or pond shorelines.
(2) 
The groundwater recharge capacity of an area being developed shall, to the maximum extent possible, be maintained where site conditions permit. The use of structural and nonstructural methods, reduction of impervious surfaces, and use of permeable pavement, where appropriate, are encouraged.
(3) 
Notwithstanding Subsection D(2) above, stormwater discharges from land uses or activities with higher potential pollutant loadings, known as "hotspots," shall not infiltrate into groundwater unless sufficient water quality treatment is provided to avoid potential water supply contamination.
(4) 
Redevelopment projects often make more efficient use of the land, and may reduce overall impacts to natural areas. Alternatives to the technical standards required by this chapter may be appropriate for certain redevelopment projects. The Design Manual describes alternative methods and sizing requirements for redevelopment projects. For those projects that the Stormwater Management Officer determines meet the definition of a redevelopment project and for which he or she determines flexibility of standards is appropriate, the applicant may use such alternative standards.
E. 
Equivalence to technical standards. Where stormwater management practices are not in accordance with the technical standards set forth in § 228-9A above, the applicant or developer must demonstrate equivalence to such technical standards, and any SWPPP must be prepared by a qualified licensed professional and approved by both the Town and New York State Department of Environmental Conservation.
A. 
Plan requirements. No application for approval of a land development activity shall be reviewed or considered until any required SWPPP or erosion and sedimentation control plan, prepared in accordance with the specifications of this chapter, is submitted to the Town of Ithaca and deemed acceptable by the Stormwater Management Officer, or his or her designee.
B.

The Town shall present the landowner with a bill for all costs and expenses incurred by the Town in connection with the remedial measures. If the landowner shall fail to pay such costs and expenses within 10 days after the demand for same, or within 30 days of the final decision on any administrative or judicial contest the landowner may pursue, then such unpaid costs, expenses and interest at the per annum rate of 9% incurred from the date of the remedial measures shall constitute a lien upon the land on which the stormwater management practices are located. A legal action or proceeding may be brought to collect such costs, expenses, interest, and recoverable attorney's fees, or to foreclose such lien. As an alternative to the maintenance of any such action, the Town may file a certificate with the Tompkins County Department of Assessment stating the costs and expenses incurred and interest accruing as aforesaid, together with a statement identifying the property and landowner. The Tompkins County Department of Assessment shall, in the preparation of the next assessment roll, assess such unpaid costs, expenses and interest upon such property. Such amount shall be included as a special ad valorem levy (administered as a move tax) against such property, shall constitute a lien, and shall be collected and enforced in the same manner, by the same proceedings, at the same time, and under the same penalties as are provided by law for collection and enforcement of real property taxes in the Town of Ithaca. The assessment of such costs, expenses and interest shall be effective even if the property would otherwise be exempt from real estate taxation.
