PROJECT DETAILS I. Introduction and Description of Facilities: The purpose of this report is to provide guidelines and information regarding the required maintenance for the proposed stormwater management facilities to be constructed in association with the development of Block 153, Lot 38 located in the Township of West Orange, in Essex County, New Jersey. The Applicant proposes to develop the lot with a 2,525 SF Popeyes fast-food restaurant with a drive-thru and a 1,484 SF Sonic restaurant with a drive-thru. Additional site amenities including, parking, landscaping, lighting, stormwater management facilities, utilities and other site amenities as shown on the accompanying Site Plan drawings. The proposed stormwater management system includes the construction of inlets and underground conveyance pipes. The stormwater management facilities will contribute toward the collection and conveyance of runoff generated by the proposed development. Every stormwater management system, whether at grade or below grade, requires that basic periodic maintenance be performed in order to maintain the proper functioning and operation of the system. This report will outline these procedures, further discuss responsibilities and highlight those responsible for performing said maintenance. The proposed stormwater management facility has been designed to accept stormwater runoff from most of the paved parking areas, drive aisles, and surrounding landscaped and open space areas. These facilities will require periodic inspections and maintenance. The following information can be considered a guideline for the continued maintenance including suggested inspection scheduling as well as performance objectives. II. Project Contacts: The applicant is responsible to maintain a detailed log of all preventative and corrective maintenance actions for the constructed stormwater facilities incorporated into the design, including record of all inspections and copies of all maintenance-related work orders. The applicant is also responsible for maintenance to evaluate the effectiveness of the maintenance plan at least once per year and adjust the plan and deed as needed. The applicant shall retain a copy of this report onsite

III. Proposed Best Management Practices: A. Routine Inspection and maintenance of Stormwater Management Facilities All stormwater management facilities have been designed to control stormwater and reduce flooding and degradation of water quality. Without proper routine inspection and maintenance, the system may lose some or all of its capability to function to its full capacity. Lack of adequate maintenance at these facilities could lead to system failures. A consulting professional engineer should perform regularly scheduled maintenance inspections of the stormwater facilities at least twice each year. In addition to the regular scheduled inspections, inspections shall also occur after any major storm events. Major storm events are defined as storm events exceeding 1” of rainfall. The primary purpose of these inspections is to ascertain the operational condition and safeties of the facilities, particularly the condition of embankments, outlet structure, rip rap and other safety-related aspects. Inspections will also provide information on the effectiveness of regularly scheduled Preventative and Aesthetic Maintenance Procedures, and will help to identify where changes in the extent and scheduling of the procedures are warranted. Finally, the facility inspections should also be used to determine the need for and timing of Corrective Maintenance procedures. Routine maintenance of this facility should be separated into two (2) basic types: Functional Maintenance and Aesthetic Maintenance. Functional Maintenance is further broken down into two Operation & Maintenance Manual 2

unctional Maintenance and Aesthetic Maintenance. Functional Maintenance is further broken down into two Operation & Maintenance Manual 2 October 2022 DEC# 1021-99-025 Last Revised June 2023

(2) categories: Preventative and Corrective. Aesthetic Maintenance, which is necessary to maintain the visual appeal and aesthetic quality of these facilities should be incorporated on the same schedule as the preventative maintenance efforts. Listed below are the Preventative, Corrective and Aesthetic Maintenance Procedures to be performed on a routine basis: 1. Preventative Maintenance Procedures: a) Removal and Disposal of Trash/Debris and Sediment: All stormwater management components expected to receive and/or trap debris and sediment must be inspected for clogging and excessive debris and sediment accumulation at least four times annually as well as after every storm exceeding one inch of rainfall. Such components include the stormwater conveyance network (piping & inlet). These stormwater management components shall be visually inspected for the accumulation of excessive sediment as well as damage in the form of cracking, erosion and rutting. Sediment build up within the stormwater conveyance network shall be removed with the use of flushing. Sediment laden water is to be captured with the use of a pipe plug, or approved equal, prior to the storage bed and simultaneously pumped out with the use of pump with sediment bag. Sediment should be disposed of in accordance with all applicable local, state and federal regulations. Removal of trash and debris will prevent possible damage to trash racks and outlet structure openings and eliminate potential mosquito breeding habitats. Debris and trash must be properly hauled off the site and transferred to an approved disposal site. b) Elimination of Potential Mosquito Breeding Habitats: The most effective mosquito control program is one that eliminates potential breeding habitats. Almost any stagnant pool of water can be attractive to mosquitoes, and may become the source of a large mosquito population. A maintenance program dedicated to eliminating potential breeding areas is preferable to chemical means of controlling mosquitoes. The most important maintenance functions, is removal of all obstructions to natural flow patterns before stagnant water conditions can develop.

2. Corrective Maintenance Procedures: a) Removal of Debris and Sediment: Sediment, debris and trash which threaten the discharge capacity of the system should be removed immediately with the use of light weight equipment to avoid soil compaction and properly disposed. As noted previously, it is recommended that all water be evacuated from the system with a pump before any significant amount of sediment, settled debris or trash is removed from the system. The lack of an available disposal site should not delay the removal of trash, debris and sediment. Temporary disposal sites should be utilized if necessary. b) Structural Repairs: Structural damage to inlet structures, roadways and walls as a result of vandalism, flood events, settlement or other causes must be repaired promptly. The urgency of the repairs will depend upon the nature of the damage and its effects on the safety and operation of the facility. The analysis of structural damage and the design and performance of structural repairs should only be undertaken by the consulting Professional Engineer. c) Snow and Ice Removal: Accumulations of snow and ice can threaten the functioning of the inlets. Provision of the equipment, material and personnel to monitor and remove snow and ice from critical areas will assure the function of the facility during the winter months. 3. Aesthetic Maintenance Procedures a) Graffiti Removal: The timely removal of graffiti will restore the aesthetic quality of the facilities. Removal can be accomplished by paint or other cover, or removal with scrapers, solvents or cleansers. Timely removal is important to discourage further graffiti and other acts of vandalism. b) Grass Trimming/Landscape Maintenance: The lawn areas shall be mowed on a regular basis as necessary to maintain the lawn at a height of 2 to 3-inches (at least once a month during the growing season). These areas shall also be fertilized twice a year, once in the spring and once in the fall. Fertilizer for lawn areas shall be 10-20-10 applied at a rate of 11 lbs. per 1,000 SF or as determined by a soil test. Any bare, dead or damaged lawn areas shall be re-seeded in accordance with the original procedures as outlined in the Soil Operation & Maintenance Manual 4 October 2022 DEC# 1021-99-025
