Public Township Council Meeting — Packet

DRAFT PROPOSED REVISIONS – OCTOBER 2011 c. The following linear development projects are exempt from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements at subsection 25- 29.4f. and g.: 1. The construction of an underground utility line provided that the disturbed areas are revegetated upon completion; 2. The construction of an aboveground utility line provided that the existing conditions are maintained to the maximum extent practicable; and 3. The construction of a public pedestrian access, such as a sidewalk or trail with a maximum width of fourteen (14) feet, provided that the access is made of permeable material. d. A waiver from strict compliance from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements at subsection 25-29.4f. and g. may be obtained for the enlargement of an existing public roadway or railroad; or the construction or enlargement of a public pedestrian access, provided that the following conditions are met: 1. The applicant demonstrates that there is a public need for the project that cannot be accomplished by any other means; 2. The applicant demonstrates through an alternatives analysis, that through the use of nonstructural and structural stormwater management strategies and measures, the option selected complies with the requirements of subsections 25-29.4f. and g. to the maximum extent practicable; 3. The applicant demonstrates that, in order to meet the requirements at subsection 25- 29.4f. and g., existing structures currently in use, such as homes and buildings would need to be condemned; and 4. The applicant demonstrates that it does not own or have other rights to areas, including the potential to obtain through condemnation lands not falling under paragraph d,3. above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate for requirements of subsection 25-29.4f. and g. that were not achievable on-site. e. Nonstructural Stormwater Management Strategies. 1. To the maximum extent practicable, the standards in subsections 25-29.4f. and g. shall be

were not achievable on-site. e. Nonstructural Stormwater Management Strategies. 1. To the maximum extent practicable, the standards in subsections 25-29.4f. and g. shall be met by incorporating nonstructural stormwater management strategies at subsection 25-29.4e. into the design. The applicant shall identify the nonstructural measures incorporated into the design of the project. If the applicant contends that it is not feasible for engineering, environmental, or safety reasons to incorporate any nonstructural stormwater management measures identified in subsection 25-29.4e,2. below into the design of a particular project, the applicant shall identify the strategy considered and provide a basis for the contention. 2. Nonstructural stormwater management measures incorporated into site design shall: (a) Protect areas that provide water quality benefits or areas particularly susceptible to erosion and sediment loss; (b) Minimize impervious surfaces and break up or disconnect the flow of runoff over impervious surfaces; (c) Maximize the protection of natural drainage features and vegetation; (d) Minimize the decrease in the "time of concentration" from preconstruction to post- construction. "Time of concentration" is defined as the time it takes for runoff to 162
