Expiration of a Stormwater Management Permit. All stormwater management permits shall expire 12 months or a maximum of 60 months when issued in conjunction with approval of a subdivision and land development plan, from the date of issuance unless an extension of time is approved. An extension of an unexpired stormwater management permit shall be issued by the Code Enforcement Officer following the submission of a written request if, in the opinion of the Code Enforcement Officer, the subject property or affected surrounding area has not been altered in a manner which requires alteration to the stormwater management plan. The refusal of an extension of time shall cite the reasons for such refusal. A stormwater management permit shall not expire while a request for an extension is pending. (Ord. 96-11, 6/26/1996, §308) §26-129. Financial Security. 1. The Code Enforcement Officer shall, prior to issuing a stormwater management permit, require financial security to be posted for the stormwater detention and/or retention basin and other drainage facilities which may adversely affect adjacent properties, streets or other public improvements in accordance with provisions outlined by subsection (2), below. 2. Financial Security. A. When required, the developer shall deposit with the Township financial security authorized by the Municipalities Planning Code and acceptable to the Board of Supervisors, in an amount equal to 110% of the estimated cost of the required improvements at a time 90 days following the date scheduled for completion of the respected improvements by the development. (1) The following requirements shall apply to any surety bond required by this Chapter: 26-21 Home Back Next WATER (2) (a) The bond shall be obtained from a surety incorporated in the United States and authorized to do business in the Commonwealth of Pennsylvania. (b) The surety shall have a current A. M. Best’s rating of no less than “A” and an underwriting capacity as stated in Best’s equal to or greater than the amount of the bond written by that surety, or in the alternative be listed on the current United States Department of the Treasury’s Annual List of “Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies” as published in the Federal Register and have an underwriting capacity in said list equal to or greater than the amount of the bond written by that surety. The following requirements shall apply to any letter of credit required by this Chapter: (a) The letter of credit shall be issued by a Federal or Commonwealth chartered lending institution have an office located within 30 miles of the boundaries of Jackson Township at which a draft on site can be presented during regular business hours. (b) The letter of credit shall have an expiration date of no earlier than 90 days after the required completion date of any improvements. The township, at its discretion, may accept a letter of credit having an earlier expiration date, provided the letter of credit states that it will automatically be renewed for a period of at least 1 year from any present or future expiration date unless the Township receives notice in writing from the issuer at least 60 days prior to the expiration date that the issuer elects to not further extend the letter of credit, and that if such notices is given the Township may draw on the letter of credit up to the amount of its unused balance on or before the relevant expiration date.

For major earth disturbance activities, the amount of financial security required by the Township shall be based upon an estimate of the cost of the improvements, submitted by the developer and prepared by a professional engineer licensed as such in this Commonwealth and certified by such engineer to be a fair and reasonable estimate of such cost. The Township, upon the recommendation of the Township Engineer, may refuse to accept such estimate for good cause shown. If the developer and the Township are unable to agree upon an estimate, then the estimate shall be recalculated and recertified by another professional engineer licensed as such in this Commonwealth and chosen mutually by the Township and the developer. The estimate certified by the third engineer shall be presumed fair and reasonable and shall be the final estimate. In the event that a third engineer is so chosen, fees for the services of said engineer shall be paid equally by the Township and the developer. C. For minor earth disturbance activities, the amount of financial security required by the Township may be based on a bona fide bid from a reputable contractor. If the developer and the Township are unable to agree on the estimate, then a second bona fide bid from a reputable contractor shall be obtained at the developer's expense and the amount of financial security shall be the greater of the two bids. D. Annually the Township may adjust the amount of required financial security by redetermining the estimated cost for completion of the uncompleted improvements as of the expiration of the 90th day after either the date scheduled for completion of a rescheduled date of completion. Subsequent to said adjustment, the Township may require the developer to post additional security in order to insure that the financial security equals 110% of the estimated cost of the Township completing the improvements at a time 90 days following the date scheduled for completion or alternatively reduce the required security so that it equals such amount. Any additional security shall be posted by the developer within 30 days after being notified of the same. E. As the work of installing the required improvements proceeds, the party posting the financial security may request the Township to release or authorize the release from time to time, such portions of the financial security necessary for the payment to the contractor or contractors performing the work. Any such request shall be in writing addressed to the Board of Supervisors and the Board of Supervisors shall request the Township Engineer to certify, in writing, to the Board of Supervisors that such portion of the work has been completed in accordance with the approved application. Upon such certification, the Board of Supervisors shall authorize release from the required financial security of an amount as estimated by the Township Engineer as representing the value of the work completed. The value of the work completed shall be determined by subtracting 110% of the estimated cost 26-23 Home Back Next WATER of the completion of the remaining uncompleted work from the total amount of security deposited. 3. When the developer has completed all of the improvements as shown on the approved application, the developer shall notify the Board of Supervisors, in writing, by certified or registered mail, of the completion of the aforesaid improvements, enclosing therewith certification by the engineer responsible for the design of the improvements that they have been installed as designed and shall send copies of the notice and certification to the Township Engineer. The Board of Supervisors shall direct and authorize the Township Engineer to inspect all of the aforesaid improvements. The Township Engineer shall thereupon file a report, in writing, with the Board of Supervisors and shall promptly mail a copy of the same to the developer. The report shall be made and mailed within 30 days after receipt by the Township Engineer of the aforesaid authorization from the Board of Supervisors, said report shall be detailed and shall indicate approval or rejection of said improvements, either in whole or in part, and if said improvements or any portion thereof shall not be approved or shall be rejected by the Township Engineer, said report shall contain a statement of the reasons for such nonapproval or rejection. The Board of Supervisors shall notify the developer of the Engineer's report, in writing, of its action with relation thereto. 4. If any portion of the said improvements shall not be approved or shall be rejected by the Board of supervisors, the developer shall proceed to complete the same and, upon completion, the same procedure of notification, as outlined herein, shall be followed. 5. Nothing herein, however, shall be construed in limitation of the developer's right to contest or question by legal proceedings or otherwise any determination of the Board of Supervisors or the Township Engineer. (Ord. 96-11, 6/26/1996, §309; and as amended by Ord. 02-11, 11/21/2002) §26-130. Liability Insurance. If, in the opinion of the Board of Supervisors based upon a report of the Township Engineer, the nature of the work is such that it may create a hazard to human life or endanger adjoining property or streets, then the Board of Supervisors shall, before issuing the permit, require that the applicant file a certificate of insurance showing that there exists insurance against claims for damage, including damage to the Township of Jackson by surface water flow which has been altered on the site. The liability insurance shall be to the amount prescribed by the Township in accordance with the nature of risks involved and include the Township as an additional insured.

Stormwater management facilities located within or affecting the floodplain of any watercourse shall also be subject to the requirements of the Jackson Township Floodplain regulations, as amended, or any future ordinances, regulating construction and development within areas of the Township subject to flooding. 4. Stormwater runoff from a project site shall flow directly into a natural watercourse or into an existing storm sewer system. If neither of these is available, the applicant shall obtain an easement from the downstream landowner to allow the runoff discharge from the 10 year storm to be piped to a natural watercourse or existing storm sewer system. Where the downstream owner will not grant such an easement, the runoff from the applicant's site shall flow onto the adjacent property in a manner similar to the runoff characteristics of the predevelopment flow. Where such an easement is granted, the 25 through 100 year discharge from the basin shall flow 26-29 Home Back Next WATER onto the adjacent property in a manner similar to the runoff characteristics of the predevelopment flow. 5. Stormwater management facilities shall be provided so that the peak rates of runoff for stormwater originating on the project site must meet the following conditions, for all watersheds (as defined by subsection (10)) within the site: A. The 2 year and 10 year postdevelopment peak flow must be less than or equal to 50% of the calculated 2 year and 10 year predevelopment peak flow, respectively, except where: (1) The permit application is filed as a minor land disturbance activity. (2) The proposed activity involves a residential subdivision of five or less single-family lots, providing that no new streets are involved. Where the application meets one of the above exceptions, the 2 year and 10 year postdevelopment peak flow must be less than or equal to the calculated 2 year and 10 year predevelopment peak flow, respectively. B. 6. The 25, 50 and 100 year postdevelopment peak flows must be less than or equal to the corresponding calculated 25, 50 and 100 year predevelopment peak flows. Stormwater management facilities shall be supplemented by BMPs as outlined in the Jackson Township BMP Design Standards, §26-147, except where: A. The permit application is filed as a minor land disturbance activity. B. The proposed activity involves a residential subdivision of five or less single-family lots, providing that no new streets are involved. Required storage volume shall be provided to minimize the impacts to water quality of receiving waters. 7. Runoff calculations for the pre- and postdevelopment comparison shall consider five different storm frequencies. (2, 10, 25, 50 and 100 year storm events.) 8. When plan applications are submitted in sections, and if temporary facilities are required for construction of a section, such facilities shall be included in the submitted plans. In the event temporary measures cannot adequately handle the stormwater runoff, the main outfall line shall be included as part of the construction of the proposed section. 9. Consideration shall be given to the relationship of the subject property to the drainage pattern of the watershed. 26-30 Home Back Next (26, PART 1) 10. Stormwater shall not be transferred from one watershed to another, unless (i) the watersheds are subwatersheds of a common watershed which join together within the perimeter of the property; or (ii) the effect of the transfer does not alter the peak discharge onto adjacent lands. 11. Stormwater runoff shall not be concentrated to, nor shall natural drainage water be diverted to, an adjacent property, nor may runoff or natural drainage be altered as to overload or further overload existing drainage structures on other private or public lands, unless adequate provisions to mitigate the effects are approved by the Township and affected owners. 12. The design plan shall minimize the disturbance and creation of steeper slopes and retaining walls. (1) No cut or fill slope shall be created that is steeper than a 2:1 slope (2 foot horizontal run to 1 foot of rise or fall). Slopes that exceed a 2:1 ratio will not be accepted unless the plan includes a report from a professional engineer that soil and subsoil conditions are such to allow a steeper slope prescribed in the statement. The report shall include construction specifications for the safe creation of these areas. The report is subject to approval by the Township engineer. (2) No retaining wall or other structure intended to hold an earth embankment from slipping shall exceed a height of 4 feet above grade on the exposed side. Where the structure exceeds 4 feet, the structure shall be designed by professional engineer. The structure shall be designed to withstand soil pressures from behind and to prevent overturning. The structure shall include provisions to remove groundwater from behind the structure, as well as a drainage system to prevent the collection of runoff. The structure shall include provisions to prevent accidental falls and shall be located a minimum of 5 feet from any property line or street right-of-way (3) All slopes, including manmade slopes, shall be maintained to be structurally sound and free from erosion or degradation.

This method is recommended and preferred for design of conveyance and retention facilities when drainage areas are greater than 1.5 square miles. C. Any other method must be approved by the Township. Criteria and assumptions to be used in the determination of stormwater runoff and design of stormwater management facilities are as follows: A. Runoff coefficients shall be based on the land use coefficients listed in Appendices No. 3 and 4 of this Part and in conjunction with the criteria outlined by §26-143(3) of this Part. B. Times of concentration shall be based on the following design parameters: (1) Overland Flow. The maximum length for each reach of overland flow before concentrated swale and/or sheet flow develops is 300 feet. The monograph in Appendix No. 5 shall be used for determination of the times of concentration. (2) Concentrated Flows. At points where overland flows concentrate in field depressions, swales, gutters, curbs or pipe collection systems, the time of concentration between these design points shall be based upon Manning's Equation and/or acceptable engineering design standards as determined by the Township Engineer. C. If the Rational Method is used, the Rainfall Intensity Duration-Frequency Chart for Region No. 1, as shown in the PennDOT Design Manual, Part 2, as amended. D. If the Soil-Cover-Complex Method is used, stormwater runoff shall be based on the following 24 hour storm events (as provided by the Pennsylvania Department of Transportation, Rainfall, Intensity - Duration Charts): [Ord. 02-11] Storm Event Inches of Rainfall 2 years 2.5 10 years 3.3 25 years 3.7 26-32 Home Back Next (26, PART 1) E. 3. Storm Event Inches of Rainfall 50 years 4.3 100 years 5.0 Use of all criteria, assumptions, references, calculation methods and/or computer modeling are subject to the approval of the Township. For the purpose of determining pre- and postdevelopment runoff coefficients, the following criteria shall be used: A. Predevelopment runoff coefficients for all areas within the site boundaries shall be based on a good grass cover unless portions of the site contain wooded areas. When the site contains wooded areas, runoff coefficients shall be based on forest/woodland cover. B. Offsite land use conditions used to determine storm flows for the pre- and postdevelopment comparison shall be based on existing land uses assuming summer or good conditions. C. Offsite land use conditions used to determine storm flows for collection and conveyance facilities shall be based on existing land uses assuming winter or poor conditions.

The following principles shall be applied to the design plan and construction schedule to minimize soil erosion and sedimentation. 4. A. Erosion and sedimentation controls designed in conformance with the Department of Environmental Protection Erosion and Sedimentation Pollution Control Program Manual shall be implemented during the construction and postconstruction periods to prevent soil erosion, sedimentation and other pollutants from entering streams, lakes, etc. B. Whenever feasible, natural vegetation shall be retained and protected. C. The extent of the disturbed area and the duration of its exposure shall be kept to a minimum. Stockpiles to remain in place longer than 20 days shall be seeded. D. It shall be the contractor's responsibility during construction to prevent soil pollution to neighboring property, public streets and streams. Soil dropped from construction equipment and sedimentation shall be immediately removed from roads, public and private property and streams. E. Drainage provisions shall accommodate the stormwater runoff both during and after construction. F. Soil erosion and sedimentation facilities shall be installed prior to any onsite earth disturbance. The maximum swale, gutter or curb velocity of stormwater runoff shall be maintained at levels which result in a stable condition both during and after construction. The following are considered characteristics of a stable condition: 26-38 Home Back Next (26, PART 1) 5. 6. A. It neither aggrades or degrades beyond tolerable limits. B. The channel banks do not erode to the extent that the channel cross section is changed appreciably. C. Sediment bars do not develop. D. Erosion does not occur around culverts and bridges or elsewhere. E. Gullies do not form or enlarge due to the entry of uncontrolled stormwater runoff. Grass lined channels shall be considered stable if the calculated velocity does not exceed the allowable velocities shown below: A. Three feet per second where only sparse vegetation can be established and maintained because of shade or soil condition. B. Four feet per second where normal growing conditions exist and vegetation is to be established by seeding. C. Five feet per second where a dense, vigorous sod can be quickly established or where water can be temporarily diverted during establishment of vegetation. Netting and mulch or other equivalent methods for establishing vegetation shall be used. D. Six feet per second where there exists a well established sod of good quality. Where swale bends occur, the allowable velocities listed above shall be divided by the following factors: A. Swale bends 0 to 30 degrees: 1.50 B. Swale bends 30 to 60 degrees: 1.75 C. Swale bends 60 to 90 degrees: 2.00 D. Swale bends 90 degrees and over: 2.50 (1) These calculated grass-lined channel flows may be exceeded if the designer can provide acceptable supportive design criteria as proof of erosion prevention. (2) Where the velocity of stormwater runoff exceeds the allowable velocity, erosion protection must be provided. (3) The method of erosion protection proposed must be supported by the appropriate design information and/or references. 26-39 Home Back Next WATER 7. Flow velocities from any storm sewer may not result in a deflection or degradation of the receiving channel. 8. Energy dissipators shall be placed at the outlets of all storm sewer pipes, culverts and bridges where flow velocities exceed maximum permitted channel velocities. (Ord. 96-11, 6/26/1996, §406; as amended by Ord. 02-11, 11/21/2002) §26-147. Design Standards; Best Management Practices (BMP). 1. Best management practices (BMPs) shall be implemented in Jackson Township in order to protect the Township's water quality. BMPs shall be applied to all applicable subdivision and land development plans and other activities regulated by this Part. 2. The purpose of these design standards is to provide designers with guidance to meet (BMP) requirements. This field is in its infancy and modifications will be necessary as new methods become available. Innovations are strongly encouraged in order to meet the objectives at a reasonable cost. 3. The strategy employed avoids the use of performance standards related to effluent standards. Instead, it establishes a suggested long-term storage volume to be provided with any proposed land use. Other design methods are available and may be utilized provided documentation is furnished and the Township Supervisors approve the design. Other measures of control, including the use of natural open space, may be substituted for structural measures. The use of non-storage related measures must be carefully evaluated to ensure the water quality goals are being met. 4. General Conditions. A. Minimize onsite impervious area. (1) Preserve natural wooded cover and drainageways onsite. (2) Preserve surfaces such as porous pavement and gravel are considered BMPs. B. Maximize the amount of onsite drainage areas that are directed to BMPs. Minimum accepted areas is 70% of the site. Impervious areas shall be directed to BMPS. C. Minimize directly connected impervious area. Promote natural removal of pollutants using vegetation and soil. Direct impervious area runoff to pervious area. For example: (1) Roof downspouts to lawns. 26-40 Home Back Next (26, PART 1) 5. (2) Driveways to lawns. (3) Parking areas to lawns or grassed swales. D. Minimize mixing of offsite and onsite runoff, unless the upstream drainage area is insignificant in size. E. Delay construction of BMPs until all other land disturbing activities are complete to minimize the potential for clogging and maintenance or remedial action. F. Incorporate the site's soil conditions to ensure the maximum life of facility. G. Use water tolerant vegetation (orchard and Bermuda grass, perennial rye, fescue, and Reed Canary grass, in swales with slopes of 2% or less and where swale dikes are utilized). H. Provide a length to width ratio in basins/ponds of at least 2:1 and avoid short circuiting. Maximize the distance between inflow and outflow. I. Provide proper erosion protection at all pipe outlets. J. Utilize underdrains for all ponds. May be used as BMP outlet if properly sized. K. Size BMP outlets to release water at a rate producing approximately a 36 hour drawdown time. Orifices should be sized to accomplish this (minimum 1/2" diameter holes). To prevent clogging around a vertical riser, use a cone of gravel or a noncorrosive fine mesh screen. L. Infiltration trenches provided for stormwater management do not require additional storage volume calculations for BMP. System of Controls. A. The Jackson Township approach to protect water quality is to minimize the impact of pollutants in stormwater runoff through a system of controls. These controls can be at the source, in the lot, at the site or at some regional facility. Examples are listed below: B. Source Controls. Eliminate the opportunity for pollutants to mix with stormwater runoff. (1) Street sweeping. (2) Cover chemical storage areas (3) Dike potential spill areas 26-41 Home Back Next WATER (4) C. D. E. 6. Regular sediment removal from drainage system Lot Controls. Minimize the potential for concentrating pollutants and concentrating stormwater runoff. (1) Minimize directly connected impervious areas. (2) Minimize impervious areas. (3) Utilize grass swales and filter strips. (4) Utilize infiltration trenches, where applicable. (5) Utilize porous pavement. Site Controls. Structural methods required to meet storage volume requirements and water quality objectives. (1) Grass swales. (2) Infiltration basins. (3) Detention ponds. (4) Wetlands. Regional Controls (D.A. > 100 Acres). Offsite structural measures for large projects. (1) Detention ponds. (2) Retention ponds. Design Procedure. A. BMP Storage Volume Calculation. (1) Measure the area of land disturbance activity on the site draining to the discharge point. (2) Compute the impervious area within the area of the land disturbance activity draining to the discharge point. (3) Compute the percentage of impervious area for the area of the land disturbance activity. 26-42 Home Back Next (26, PART 1) (4) Determine the storage requirement using Chart A and the impervious percentage calculated in subsection (6)(A)(6), Step 3, for the type of watershed. (5) Compute the required storage volume by multiplying the storage requirements times the total drainage area to the discharge point. (6) Sample Calculation. Given: 100 acre site in high quality watershed drainage area to discharge point: 80 acres land disturbance area: 10 acres impervious area: 6 acres Step (1) 10 acres Step (2) 6 acres Step (3) (6 10) x 100 = 60% Step (4) from Chart A-1, 750 CF/acre Step (5) 1750 x 80 = 140,000 CF Total BMP Storage Volume = 140,000 CF B. Storage Volume Reduction for Filter Strip and Grass Swale Effectiveness. (1) Filter strips and grass swales are very effective methods of removing pollutants in stormwater runoff. The BMP storage volume can be reduced when properly designed filter strips and grass swales are incorporated into the site layout. The percent reduction is read directly from Chart B using the flow length of the appropriate measure. The maximum reduction allowed for residential/agricultural uses is 80% and the maximum reduction allowed for commercial/industrial uses is 50%. Some other method shall be provided to achieve the total storage volume. (2) Sample Calculation. Given: required storage volume = 140,000 CF commercial development filter strip flow length: 100 feet 26-43 Home Back Next WATER grass swale flow length: 400 feet Storage Volume Reduction from Chart B: filter strip reduction: 25% grass swale reduction: 50% total reduction = 75% use: 50%: maximum % allowed Storage Volume Adjustment 140,000 x .50 = 70,000 CF 7. Design Standards. A. Filter Strip. Vegetative strip across which stormwater sheet flows before entering the stormwater collection system.

If infiltration trenches are sizes for stormwater management purposes, no additional calculations are required. If the infiltration trench is provided for BMP only, then follow the design procedure in subsection (6)(A), above. (6) Sample Calculation. Given: percolation rate: 1 inch/hr. required storage volume: 1,750 CF trench volume: 1,750 40 = 4,375 CF drawdown: trench depth perc. rate = 36 inches; 1inch/hr. = 36 hrs ok See Appendix 10 for sample detail. D. Infiltration Basin. Shallow excavation or depression for the storage of stormwater for infiltration. (1) Maximum drainage area: 5 acres. (2) Storage Volume: see design procedure. (3) High seasonal water table or bedrock at minimum of 2 feet below bottom elevation. Soil sampling or augering required. (4) Permeability: see §26-147(7)(C)(3). (5) Maximum side slopes: 3:1. See Appendix 10 for sample detail. 26-45 Home Back Next WATER E. Extended Dry Detention Ponds. Modified stormwater detention basin.

Includes swamps, marshes and bogs. Wetlands can be very effective in the removal of pollutants from stormwater runoff. (1) For design criteria refer to most recent Penn DER Design Manual. (2) Inflow must be greater than infiltration rate. (3) Depth Requirements. 25% @ 2 -3 feet deep near the outlet 25% @ 6-12 inches deep 50% @ 6 inches deep near the inflow (4) H. Length to width ratio: 2:1. Water Quality Inlet. For use only with small parking areas with oily wastes. (1) Volume: 200 cu. ft. per impervious acre See Appendix 10 for sample details. 8. Maintenance Considerations. A. Maintenance is an essential part of the successful functioning of a BMP system. B. Responsibility for maintenance of BMP facilities during and after construction shall be in accordance with §26-151 of this Chapter. (Ord. 96-11, 6/26/1996, §407) 26-47 Home Back Next §26-148. Stormwater Management Districts. The Township shall comply with the applicable provisions of the Butler County Stormwater Management Plan upon adoption of said plan. If the provisions of this Part are sufficient to regulate development within the Township in a manner consistent with the Butler County Stormwater Management Plan, this Part shall be deemed to satisfy the requirements of Section 11(b) of Act 167 without the necessity of reenactment. (Ord. 96-11, 6/26/1996, §408) 26-48 Home Back Next (26, PART 1) E. Construction and Maintenance. §26-151. Construction and Maintenance of Stormwater Management Facilities and BMP Facilities. Construction and maintenance are essential parts of the successful functioning of a stormwater management system. The developer and/or landowner shall be solely responsible to institute, construct and complete the stormwater management facilities, erosion and sedimentation control measures, BMP facilities, and any other features approved as part of the permit. The developer and/or landowner shall institute, construct, complete, and maintain all features, facilities, devices and improvements in strict accordance with the provisions of the approved application materials, and the terms of this Part. [Ord. 02-11] A. B. Maintenance during development of a project shall be the responsibility of the developer and/or landowner and shall usually include, but not be limited to: (1) Removal of silt from sediment traps when 35% and sediment basins when 28% of capacity is filled with silt. (2) Periodic maintenance of temporary control facilities such as replacement of straw bale dikes, straw filters, silt fence or similar measures. (3) Establishment or reestablishment of vegetation by seeding and mulching or sodding of scoured areas or areas where vegetation has not successfully been established. (4) Installation of necessary controls to correct unforeseen problems caused by storm events within design frequencies. (5) The contractor or developer shall be responsible for removal of all temporary measures and installation of permanent measures upon completion of the project. Maintenance of Project After Physical Completion. (1) It is the purpose of this Part that the Township shall not become responsible for maintenance and supervision of developed areas. Such responsibility falls upon the party responsible for land development who shall remain personally responsible for those areas of the development which are subject to the requirements of this Part. This responsibility may be retained or assigned to third persons as is deemed most acceptable to the party responsible for land development. In the event that any portion of land development would, but for the existence of areas requiring maintenance subject to this Part, be dedicated to the Township, the contractor or developer may make application to the Township for acceptance by the Township of such portions of the land development. In the event that the Township, by formal action, accepts 26-49 Home Back Next WATER such portions of land development, maintenance and responsibility for such portions shall fall upon the Township. (2) It is the intent of this Part that the purposes of this Part shall be carried out through the exercise of responsibility by private parties, and therefore it is anticipated that control plans shall be developed with the view towards projects which can effectively be contained within the tracts to be owned and maintained by private parties. To foster this purpose, with respect to portions or parts of a project as shown on a plan of a developer or contractor, which portions will not otherwise become part of Township property, such portions shall become the responsibility of the individual property owners on whose property such portions of a project lie including, but not limited to, retention ponds, detention ponds, sediment basins, energy dissipators, or grassed waterways. Persons, including contractors and developers, conveying property of a development to another party, which property contains any portions of a stormwater management plan, after that plan has been established, shall include a specific deed reference to such grantee's responsibility for the maintenance and care of the portions of such project as are included within said grantee's conveyed property. The deed reference to such portions shall be in the form of a deed restriction imposing responsibilities upon said property owner for the maintenance of the portions of the project maintenance of the project in accordance with the terms of this Part. Such maintenance shall include the following: (a) Liming and fertilizing vegetated channels and other areas according to specifications in the "Penn State Agronomy Guide." (b) Reestablishment of vegetation by seeding and mulching or sodding of scoured areas or areas where vegetation has not been successfully established. (c) Mowing as necessary to maintain adequate strands of grass and to control weeds. Chemical weed control may be used if State and local regulations are met. (d) Removal of silt from all permanent structures which trap silt or sediment in order to keep the material from building up in grass waterways thus reducing their capacity. (e) Regular inspection of the areas in question to assure proper maintenance and care. (f) Removal of silt from all permanent drainage structures, in particular BMPs, in order to maintain the design storage volumes. Regular programs shall be established and maintained. 26-50 Home Back Next (26, PART 1) (3) In order to provide additional notification to successive property owners of the requirements to maintain stormwater management facilities, the developer shall enter into a stormwater management agreement and declaration of easement with the Township, in a form acceptable to the Township Solicitor, which shall be recorded in the Office of the Recorder of Deeds in and for Butler County. The stormwater management agreement and declaration of easement shall be recorded prior to the issuance of a stormwater management permit. (4) The deed restrictions hereinabove mentioned shall also include notice that in the event the individual property owners should fail to comply with the terms of this Part for the maintenance and care of the land in question, the Township of Jackson shall have the authority to carry out those duties hereby imposed upon individual property owners. The Township may, after giving notice to an individual property owner that he is not properly maintaining the areas subject to this Part, and by making demand that such compliance shall be made within 30 days, enter upon said private property and take such actions as may be required to bring the area into compliance with this Part. The Township shall further have the right to file a municipal lien against such property for the cost of maintenance work carried out under this Section. The Township shall, in addition to the filing of a municipal line, have any other remedies provided by law against any property owner who should fail to comply with the terms of this Part. (5) Stormwater management facilities existing on the effective date of this Part on individual lots, which have not been accepted by the Township or for which maintenance responsibility has not been assumed by a private entity such as a homeowner's association, shall be maintained by the individual property owners. Such maintenance shall include at a minimum those items set forth in subsection (B)(2), above. If the Township determines at any time that any permanent stormwater management facility has been eliminated, altered, blocked through the erection of structures or the deposit of materials or improperly maintained, the Township may determine that such condition constitutes a nuisance and shall notify the property owner of corrective measures which are required and provide for a reasonable period of time, not be exceed 30 days, within which the landowner shall take such corrective action. If the property owner does not take the required corrective action, the Township may either perform the work or contract for the performance of the work and bill the property owner for the cost of the work plus a penalty of 10% of the cost of the work. If such bill is not paid by the property owner within 30 days, the Township may file a municipal claim against the property upon which the work was performed in accordance with applicable laws. (6) Where the Board of Supervisors accepts dedication of all or some of the required stormwater management facilities following completion, the 26-51 Home Back Next WATER Board of Supervisors may require the posting of financial security to secure structural integrity of said facilities as well as the functioning of said facilities in accordance with the design and specifications as depicted on the approved stormwater management plan for a term not to exceed 18 months from the date of acceptance of dedication. Said financial security shall be the same type as required with regard to installation of such facilities, and the amount of the financial security shall not exceed 15% of the actual cost of installation of said facilities. (Ord. 96-11, 6/26/1996, §501; as amended by Ord. 02-11, 11/21/2002) §26-152. 1. Permanence of Stormwater Management Facilities. Permanence of Stormwater Management Facilities. No person shall modify, remove, fill, landscape or alter stormwater management facilities and/or BMP facilities which may have been installed on a property unless a stormwater management permit has been obtained to permit such modification, removal, filling, landscaping or alteration. No person shall place any structure, fill, landscaping or vegetation into a stormwater management facility, a BMP facility or within a drainage easement which will limit or alter the functioning of the facility or easement in any manner.
