NOTICE OF PUBLIC HEARING
The following is intended to amend Section 22 of the Code of Ordinance in the Town of Jamestown. A public hearing to solicit public input is scheduled on Tuesday December 6, 2005 at 7:00 p.m. in the large conference room of the Jamestown Philomenian Library, 26 North Road.
AN ORDINANCE AMENDING CHAPTER 22 OF THE CODE OF ORDINANCES OF THE
TOWN OF JAMESTOWN
THE TOWN OF JAMESTOWN HEREBY ORDAINS AS FOLLOWS:
Section 1. Article V of Chapter 22 of the Jamestown Code of Ordinances is hereby amended by adding the following new Division thereto
Division 3. Post Construction Stormwater Control Sec. 22-256. Purpose.
Unmitigated storm water from areas altered by development may pose public health and safety threats. Potential contaminants in storm water runoff may include suspended solids, nitrogen, phosphorus, hydrocarbons, heavy metals, pathogenic organisms (bacteria and viruses), and road salts.
This ordinance establishes the administrative mechanisms necessary for The Town of Jamestown to ensure proper storm water management. The ordinance is written to work in conjunction with current state regulations.
Sec. 22-257. Applicability.
This ordinance shall apply to any major or minor subdivision, land development project, or other development occurring within the Town of Jamestown involving an area or areas of disturbance which total one acre or more. No person shall engage in such development activities without receiving approval of the a Stormwater Management Plan for the development.
Section 22-258. Technical Standards
All applicants must develop and submit a proposed Storm Water Management Plan which must address storm water management for the development which meets all the requirements of this ordinance. All such storm water management shall be consistent with the Rhode Island Stormwater Design and Installation Standards Manual and the Rhode Island Soil Erosion and Sediment Control Handbook, as amended. The stormwater management plan must include a description of proposed best management practices (BMPs), detailed site plans, and a written narrative, that when implemented, provides protection of receiving waters by reducing pollutant loadings and other negative impacts associated with changes in land use as described below. Structural BMPs are described as structural stormwater devices that temporarily detain and treat stormwater runoff in order to reduce pollutant loadings. Typical BMPs include wet ponds, extended detention ponds, infiltration trenches, created wetlands, grassed swales and the like.
A. Performance Standards
Storm Water Management Plans must incorporate best management practices for water quality control, which in combination are demonstrated to reduce the average annual total suspended solids in post development runoff by eighty percent (80%). Development in drinking water supply watersheds or watersheds where impaired waters as defined by the State’s 303(d) list exist may be held to higher standards.
B. Disallowed Storm Water Best Management Practices
The placement of structural BMPs and other storm water structures within a floodplain shall be avoided. If there is no alternative, the applicant must show what effects, if any, the tail waters created by the floodplain will have on the outflow and effective storage capacity of the detention facility.
C. Facilitation of Maintenance
Facilities that require maintenance shall be designed to minimize the need for regular maintenance, facilitate required maintenance, and ensure accessibility of components that require maintenance. At a minimum, all Storm Water Management Plans must incorporate structural BMPs with appropriate maintenance design in accordance with the Rhode Island Stormwater Design and Installation Standards Manual, as amended; or the Rhode Island Soil Erosion and Sediment Control Handbook, as amended.
Sec. 22-259. Maintenance Requirements for Best Management Practices
A. Routine Maintenance and Repair Procedures
Preventative maintenance procedures are required to maintain the intended operation and safe condition of the structural BMPs by greatly reducing the occurrence of problems and malfunctions. To be effective, preventative maintenance shall be performed on a regular basis and include such routine procedures as training of staff, periodic inspections, grass cutting elimination of mosquito breeding habitats, and pond maintenance. Disposal of sediment and debris must occur on a regular basis (unless otherwise specified within an approved plan), at suitable disposal sites or recycling sites and comply with applicable local, state and federal regulations.
Corrective maintenance procedures are required to correct a problem or malfunction at a storm water management facility and to restore the facility's intended operation and safe condition. Based upon the severity of the problem, corrective maintenance must be performed on an as-needed or emergency basis and include such procedures as structural repairs, removal of debris, sediment and trash removal which threaten discharge capacity, erosion repair, snow and ice removal, fence repair, mosquito extermination, and restoration of vegetated and nonvegetated linings.
B. General Maintenance Standards for Storm Water Best Management Practices.
Maintenance design and maintenance procedures for all structural BMPs shall be in accordance Rhode Island Stormwater Design and Installation Standards Manual, as amended; or the Rhode Island Soil Erosion and Sediment Control Handbook, as amended. Storm Water Management Plans shall demonstrate appropriate maintenance design and procedures for each proposed best management practice.
A maintenance schedule for each type of structural BMP must be included in the Storm Water Management Plan. These schedules shall list the frequency and type of maintenance operations necessary along with the legally responsible party’s name, address, and telephone number. If the storm water drainage system is to be deeded to the local municipality the applicant must obtain a letter from the municipality acknowledging maintenance responsibility and intent of ownership.
Sec. 22-260. Storm Water Management Plans A. Calculations
In addition to the information required for Storm Water Management Plans the following information must also be included with the application, where applicable.
1. The area of each subwatershed as identified on final site plans.
2. The area of impervious surfaces (including all roads, driveways, rooftops, sidewalks, etc.) for each subwatershed as identified in the Rhode Island Stormwater Design and Installation Standards Manual, as amended.
3. Weighted curve numbers, (CN) as determined by the SCS TR-55 method, for each subwatershed as identified in the Rhode Island Stormwater Design and Installation Standards Manual, as amended.
4. Invert elevations for all applicable structural BMPs. In addition, the elevations for permanent and/or flood pool stages, including peak discharge rates for each stage, within all stormwater basins are required.
5. The total volume capacity for structural BMPs (e.g., infiltration basin, detention basins, wet ponds, etc.). Volumes must be segregated into permanent and flood pool stage volumes where applicable. Furthermore, the volumes of all sediment storage (basins, forebays, etc.) areas must also be shown.
6. The water quality volume must also be calculated for each subwatershed. All relevant variables such as curve numbers and time of concentration, along with the supporting computations and worksheets must be included.
B. Narrative Description
As part of the Storm Water Management Plan, the applicant shall include a discussion of the protection of environmental resource functions and values. The following outline is provided as guidance for preparing a narrative description for the Storm Water Management Plan. Depending on the size and scope of the proposed project, the amount of information required by the permitting agency may vary, therefore, it is advised to consult the appropriate permitting agency for specific requirements.
1. Site description – general topography, soil types, current vegetative composition and relative abundance, existing infrastructure, and/or adjacent properties, identification of major resources (e.g., wetlands, groundwater, surface waters, etc.), name of receiving water(s), potential water quality and/or hydrologic impacts on resources.
