1.0 PROJECT DETAILS 1.1 Introduction and Description of Facilities: The site is located on a parcel known as Block 152.01, Lot 1445.01 as described on the Township of West Orange Tax Map #79. The project site has frontage on Eagle Rock Avenue, Township of West Orange, within the B-2, General Business Zone with an IHO-1 Inclusionary Housing Overlay. The site is bordered to the north by a large, wooded area, to the east by a mixed-use commercial complex and to the west by residential homes. The previously constructed and developed site includes a +/- 28,000 sf principal building, a +/- 1,700 sf accessory structure and shed. Additionally, the site currently has a large concrete pad with a canopy which is utilized for the added tenant, Remarkable Foods, Inc. The proposed drainage improvements are designed to be preventative as the existing grade sheets overland flow toward the existing and proposed concrete pads. The proposed improvements for the site include two rectangular concrete pads, +/-550 sf and +/-1,000sf. Each of the proposed pads will have an accompanying canopy fitted with roof drains at the corners. Under post-development conditions, the stormwater management facilities will include perforated pipes within stone trenches along the perimeter of the pads for stormwater collection from both overland sheet flow and the canopy roof drains. The perforated pipes are proposed to aid in diverting runoff away from the pads and follow existing drainage patterns. This manual consists of three parts. The first part includes the introduction, project description and a list of project contacts. The second part provides the operation and maintenance instructions for the facilities and equipment. The third part (Appendix) provides information regarding the inspection and maintenance activities. 1.2 Project Contacts: Municipal Engineer: 25 Lakeside Avenue West Orange, NJ 07052 Phone: (973) 325-4165 Attn: Zayibeth Carballo Director/Superintendent of Public Works 25 Lakeside Avenue West Orange, NJ 07052 Phone: (973) 325-4153 Attn: Louis Reynolds Site Design Engineer: Bohler Engineering NJ, LLC 30 Garber Square Ridgewood, NJ 07450 Phone: (551) 307-1400 Attn: Benjamin S.

Without proper routine inspection and maintenance, the basins may lose some or all of their capability to function to their full capacity. Lack of adequate maintenance at these facilities could lead to system failures. Regularly scheduled maintenance inspections of the stormwater facilities should be performed at least four (4) times each year. The primary purpose of these inspections is to ascertain the operational condition and safety of the facilities, particularly the condition of embankments, outlet structures, sedimentation 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 these facilities should be separated into two (2) basic types: Functional Maintenance and Aesthetic Maintenance. Functional Maintenance is further broken down into two (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 2.1.1. Preventative Maintenance Procedures: The purpose of Preventative Maintenance is to maximize the effectiveness of the stormwater management aspects of the basins so that they remain operational and safe and to minimize the need for potential emergency or extensive corrective maintenance. These procedures are as follows: a) Weed Growth: Weeds associated with detention

they remain operational and safe and to minimize the need for potential emergency or extensive corrective maintenance. These procedures are as follows: a) Weed Growth: Weeds associated with detention basins typically fall into three (3) categories: submergent, floating and emergent. All three (3) are typically found, to some

b) Maintenance of Adjacent Areas: c) Removal and Disposal of Trash/Debris and Sediment:

b) Structural Repairs: c) Embankment and Slope Repairs: d) Weed Harvesting: e) Extermination of Mosquitoes: f) Erosion Repair:

g) Elimination of Trees, Brush, Roots and Animal Burrows: h) Snow and Ice Removal: a) Graffiti Removal: b) Grass Trimming/Landscape Maintenance:

Sediment Control Plans using the same mix and seeding rates. Stabilization of bare or damaged areas shall be done in a timely fashion so as to avoid exposing the soil to erosion. If season prevents the re-establishment of turf cover, exposed areas should be stabilized with straw or salt hay mulch as described in the Soil Erosion and Sediment Control Plans until permanent seeding can be done. Seeding can be done between March 15% and June 15'° and between September 15" and December 1*, only if adequate water is provided The shrubs around the basins should also be maintained in order to promote a neat appearance and healthy, vigorous growth. All shrubs should be allowed to grow together in masses as shown on the plans and not pruned into individual plants. The planting beds should be mulched with hardwood mulch every two (2) years in order to provide a suitable growing medium for the shrubbery and to retain moisture around the root zones. Pruning of shrubs should also be done on a regular basis to maintain the shape and appearance of the shrub masses. The height of the shrubs may vary according to the plants natural growth habits, but should not exceed 6-feet. Pruning should be done as necessary throughout the year to remove dead branches and to control new growth. Any pruning, other than the removal of dead branches, should be done in either late winter/early spring or after the shrub has flowered in the spring. In the event that a shrub should experience more than 2/3 die back, it should be replaced in kind as soon as possible in either the spring or fall planting season. The replacement shrub should be the same species as the original and installed at the size and condition as specified on the original landscape plans. If, for any reason, a substitution of species or size must be made, it shall be subject to the approval of the project Landscape Architect. The trees surrounding the basin areas shall be maintained regularly to ensure good health and exhibit an attractive appearance. Their maintenance should include fertilization twice annually, with one application in the spring and another in early fall. The trees shall be pruned in the late winter or early spring. However, dead branches should be removed as soon as they are noticed. Care should be taken to avoid cutting off the central leader of a tree if one is present. If a tree is severely damaged
