1. Protect areas that provide water quality benefits or areas particularly susceptible to erosion and sediment loss. The footprint of the improvements has been minimized to the previously improved and/or disturbed areas. The majority of the existing wooded areas remain undisturbed. Stormwater runoff will be discharged in a similar manner of existing conditions. Riparian zone and wetland disturbance has been minimized to continue providing water quality benefits. 2. Minimize impervious surfaces and break up or disconnect the flow of runoff over impervious surfaces. The overall impervious coverage is reduced by 0.07 AC. As part of the proposed site design, the minimum allowable parking and drive aisle sizes, in accordance with local ordinances, are used in lieu of larger stalls and aisles to reduce the amount of impervious surface in the post-development condition. Additionally, Pervious pavement is proposed in a portion of the parking lot. 3. Maximize the protection of natural drainage features and vegetation. The footprint of the improvements has been minimized to the previously developed area. All of the existing wooded areas remain undisturbed. Stormwater runoff will be discharged in a similar manner of existing conditions. Riparian zone and wetland disturbance has been minimized to continue providing water quality benefits. Soil erosion measures are proposed to be utilized during construction to protect the adjoining riparian zones, wetlands, tributary corridors, and undisturbed vegetation. 4. Minimize the decrease in the "time of concentration" from pre-construction to postconstruction. Pervious pavement has been included within the project’s stormwater design to achieve maximized times of concentration. Unretained stormwater runoff from the remaining portion of the site will flow over the parking lot to the Rahway River as it does in existing conditions. The portions of the site where mill and overlay is proposed has been designed to match existing grade as closely as possible to avoid changing the existing flow paths and times of concentration. 5. Minimize soil compaction. The project is located in Planning Area 1 (PA-1) therefore soil compaction is not required. 6. Provide low-maintenance landscaping that encourages retention and planting of native vegetation and minimizes the use of lawns, fertilizers, and pesticides. A comprehensive

ction is not required. 6. Provide low-maintenance landscaping that encourages retention and planting of native vegetation and minimizes the use of lawns, fertilizers, and pesticides. A comprehensive landscape plan has been incorporated into the design of the proposed improvements which includes low maintenance landscaping. The use of lawn areas has been minimized where applicable and fertilizers and pesticides are to be used sparingly. Native plants, including ground cover, shrubs and trees, are proposed. The native plantings will also require little or no irrigation once they are established. 7. Provide other source controls to prevent or minimize the use or exposure of pollutants from development sites in order to prevent or minimize the release of those pollutants into stormwater runoff. These source controls include, but are not limited to: ▪ Stormwater Management Report for Proposed Retail Store▪ 8 ▪ December 2025 ▪
