The certification statement(s) shall become part of the SWPPP for the land development activity.
D. 
A copy of the SWPPP shall be retained at the site of the land development activity during construction from the date of initiation of construction activities to the date of final stabilization.
A. 
Technical standards. For the purpose of this chapter, the following documents shall serve as the official guides and specifications for stormwater management design. Stormwater management practices that are designed and constructed in accordance with these technical documents shall be presumed to meet the standards imposed by this chapter:
(1) 
The New York State Stormwater Management Design Manual (New York State Department of Environmental Conservation, most current version or its successor, hereafter referred to as the "Design Manual").
(2) 
New York Standards and Specifications for Erosion and Sediment Control (Empire State Chapter of the Soil and Water Conservation Society, 2004, most current version or its successor, hereafter referred to as the "Erosion Control Manual").
B. 
Equivalence to technical standards. Where stormwater management practices are not in accordance with technical standards, the applicant or developer must demonstrate through equivalence to the technical standards set forth in Subsection A of this § 140-12 and the SWPPP shall be prepared by a licensed professional engineer, landscape architect, or certified erosion control specialist.
C. 
Water quality standards. 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.
The following principles shall apply to all land development activities within the Town of Cazenovia and to the preparation of the submissions required under this chapter:
A. 
The selection of stormwater management, erosion, and sediment control measures shall be based on an assessment of the probable frequency of climatic and other events likely to contribute to erosion, and on an evaluation of the risks, costs, and benefits involved.
B. 
Properties adjacent to the site of a land disturbance shall be protected from sediment deposition. This may be accomplished by preserving a well-vegetated buffer strip around the lower perimeter of a land disturbance, by installing perimeter controls such as sediment barriers, filters, dikes, or sediment basins, or by a combination of such measures. Vegetated buffer strips may be used alone only where runoff in sheet flow is expected. Buffer strips should be at least 20 feet in width. If, at any time, it is found that a vegetated buffer strip alone is ineffective in preventing sediment movement onto adjacent property, additional perimeter controls must be provided.
C. 
Development shall reflect the topography and soils of the site so as to create the least potential for erosion. Areas of steep slopes where high cuts and fills may be required shall be avoided wherever possible, and natural contours shall be followed as closely as possible.
D. 
Natural vegetation shall be retained and protected wherever possible. A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation and related structures shall be installed as soon as practical, or within the time limit specified in the permit. Permanent vegetation shall not be considered established until a groundcover is achieved which, in the opinion of the Stormwater Management Officer, or designated agent, is mature enough to control soil erosion satisfactorily and to survive severe weather conditions.
E. 
Permanent or temporary soil stabilization must be applied to denuded areas within 15 days after final grade is reached on any portion of the site. Soil stabilization must also be applied within 15 days to denuded areas which may not be at final grade but will remain dormant or undisturbed for more than 60 days. Soil stabilization refers to measures which protect soil from the erosive forces of raindrop impact and flowing water. Applicable practices include vegetative establishment, mulching, and the early application of gravel base on areas to be paved.
F. 
Sediment basins, debris basins, silt traps, sediment barriers, filters, or other measures intended to trap sediment on-site shall be installed and maintained to remove sediment from runoff waters before any upslope land disturbance takes place.
G. 
All on-site stormwater conveyance channels and detention systems shall be designed and constructed to withstand the expected critical velocity of flow from a ten-year frequency storm without erosion. Stabilization adequate to prevent erosion must also be provided at the outlets of all pipes and paved channels.
H. 
All existing stormwater inlets shall be protected so that sediment-laden water will not enter the stormwater collection system without first being filtered or otherwise treated to remove sediment.
I. 
Construction vehicles should be kept out of watercourses to the greatest extent possible. Where in-channel work is necessary, precautions must be taken to stabilize the work area during construction to minimize erosion. This may include blocking of the flow and transporting water around the work area. The channel (including the bed and banks) must be restabilized immediately after in-channel work is completed. Where a live or wet watercourse must be crossed by construction vehicles regularly during construction, a temporary stream crossing must be provided.
J. 
Wherever construction vehicle access routes intersect paved public roads, provisions must be made to minimize the transport of sediment by runoff or vehicle tracking onto the paved surface. Where sediment is transported onto public road surfaces, the roads shall be cleaned thoroughly at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and transported to a sediment control area. Street washing shall be allowed only after sediment is removed in this manner.
K. 
All temporary erosion and sediment control measures shall be disposed of within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed, unless authorized by the Stormwater Management Officer. Trapped sediment and other disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation.
L. 
All temporary and permanent erosion and sediment control practices must be maintained and repaired as needed to assure continued performance of their intended function.
M. 
All land development activities exceeding one acre in developed area, or stream crossings, may also be regulated by NYSDEC permits. Contact NYSDEC to confirm applicability of NYSDEC permits.
A. 
Maintenance and inspection during construction.
(1) 
The applicant or developer of the land development activity or his or her representative shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the applicant or developer to achieve compliance with the conditions of this chapter. Sediment shall be removed from sediment traps or sediment ponds whenever their design capacity has been reduced by 50%.
(2) 
For land development activities as defined in this chapter and meeting Condition A, B or C in § 140-9B, the applicant shall have a qualified professional (i.e., prime construction contractor, registered professional engineer, registered landscape architect, or certified erosion control specialist) conduct site inspections and document, in writing, the effectiveness of all erosion and sediment control practices every seven days and within 24 hours of any storm event producing 0.5 inch of rainfall or more. Inspection reports shall be maintained in a site logbook.
(3) 
The applicant or developer or his or her representative shall be on site at all times when construction or grading activity takes place and shall inspect and document the effectiveness of all erosion and sediment control practices.
B. 
Maintenance easement(s). Prior to the issuance of any approval that has a stormwater management facility as one of the requirements, the applicant or developer must execute a maintenance easement that shall be binding on all subsequent landowners served by the stormwater management facility. The easement shall provide for access to the facility at reasonable times for periodic inspection by the Town of Cazenovia to ensure that the facility is maintained in proper working condition to meet design standards and any other provisions established by this chapter. The easement shall be recorded by the grantor in the office of the County Clerk after approval by the counsel for the Town of Cazenovia. Preparation and recording or said easement shall be the sole cost and expense of the applicant/developer.
C. 
Maintenance after construction. The owner or operator of permanent stormwater management practices installed in accordance with this chapter shall ensure they are operated and maintained to achieve the goals of this chapter. Proper operation and maintenance also includes, as a minimum, the following:
(1) 
A preventive/corrective maintenance program for all critical facilities and systems of treatment and control (or related appurtenances) which are installed or used by the owner or operator to achieve the goals of this chapter.
(2) 
Written procedures for operation and maintenance and training new maintenance personnel.
(3) 
Discharges from the SMPs shall not exceed design criteria or cause or contribute to water quality standard violations in accordance with § 140-12.
D. 
Maintenance agreements. The Town of Cazenovia shall approve a formal maintenance agreement for stormwater management facilities binding on all subsequent landowners and recorded in the office of the County Clerk as a deed restriction on the property prior to final plan approval. The maintenance agreement shall be in a form satisfactory to the Town Board. The Town of Cazenovia, in lieu of a maintenance agreement, at its sole discretion, may accept dedication of any existing or future stormwater management facility, provided such facility meets all the requirements of this chapter and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance.
