The project consists of a mixed-use retail, office and residential facility that consists of 11 "blocks" / buildings which are interconnected through pedestrian walk -ways and includes a rooftop park. The following report provides a preliminary Waste Management Plan for servicing this 50 -acre site based on a preliminary estimate of waste generation, a conceptual program for waste handling systems, and equipment and space program for the new Vallco Town Center in Cupertino, Ca. 1.2 INTENT OF THIS DOCUMENT This Preliminary Waste Management Plan document is intended to provide the City of Cupertino Planning, Public Works, and Environmental Programs with an understanding of the preliminary loading, estimated size allocations, and different service strategies intended for the waste management of the Vallco Town Center site. The applicant met on July 31, 2018 with Public Works, Environmental Programs, and Recology to review these materials to supplement the SB 35 Planning Application. A finalized Waste Management Plan indicating actual sizes, generation rates, equipment, and final systems will be submitted for review at the time of building permits. The preliminary and final solid waste and recycling planning shall follow all applicable California State and local Cupertino Municipal Codes and goals for recycling, including state Assembly Bills AB341, AB939 and AB 1826, and City of Cupertino Municipal Codes 6.24 and 9.16. 1.3 EXECUTIVE SUMMARY Given the nature of the Project site, the proposed uses, and the square footage of Project programs outlined in the SB 35 Planning Application drawings, wastes will be generated from residences, commercial retail tenants, offices, facility maintenance, plazas / garden / park area, parking, and general street / walk -ways. These wastes will be collected and transported vertically in building cores through a combination of trash chutes and / or service elevators to storage rooms in the basement based on the type of waste collected. From these locations, they will be collected by the operations personnel and transported horizontally to one of two Central Waste Terminals (CWT). It is from these locations that the City's contracted third -party hauler as well as additional private haulers will remove the waste and transport it to the appropriate off-site facility. 1.4 EXPECTED WASTE STREAMS The principle waste streams which volume is significant enough to justify larger compactor -container equipment include the following: 1. General Trash 2. Organic Wastes 3. Commingled Recyclables (single -stream plastics, glass, metals/cans, clean paper) 4. Cardboard Page 1 3 Preliminary Waste Management Plan Vallco Town Center Cupertino, California 22 August 2018 In addition, specialty waste streams that will be staged for pick-up in carts, dumpster bins, secured cage/room, hazardous or flammable cabinets, etc. These include: 1. E -Waste - print cartridges, computers, electronic cords, phones, etc. 2. Donatable Materials - clothing, household items, furniture, non-perishable food, etc. 3. Recyclable Hazardous Waste - batteries (particularly lithium based which are increasingly mandated for separation from landfill), light bulbs, cooking oil, etc. 4. Non -Recyclable Hazardous Waste - paints, aerosols cans, chemicals, hazardous oils, bio- medical / sharps (needles) waste, etc. 1.5 PRELIMINARY WASTE MANAGEMENT STRATEGY 1.4.1 Overview - Central Waste Terminals (CWT) The overall principle strategy is to efficiently collect waste streams from disparate locations across the project site vertically into easily accessible centralized locations per block in back -of house basement storage rooms and then horizontally transport the materials to a small number of centralized pick-up locations for waste haulers. There are multiple reasons for this, including reducing hauler costs, efficiencies generated by utilizing larger collection / staging equipment and areas, establishing central soiled dock locations resulting in better hygienic control (including centralized trash can / cart washing), reducing truck transport to / from and on-site, etc. Two (2) centralized locations have been identified for establishing "Central Waste Terminals" (CWT), one at the East -side of Wolfe Road that handles Blocks 7 - 11, and one on the West -side of Wolfe Road that handles Blocks 1 - 6.

Each program (residential, office, and retail) will be separated in the below -grade staging areas within the building core areas and located adjacent to loading zones. Retail and roof -top / public areas will be transported by hand down service elevators and will share centralized compactor -containers and staging areas.

Page 1 5 Preliminary Waste Management Plan 1.4.2 Residential Waste Strategy Vallco Town Center Cupertino, California 22 August 2018 Residences will utilize a system of vertical chutes in trash rooms located on each floor that are connected to bin / cart receiving at the basement level, or connected to a Pneumatic Waste System (PWS) for the principle waste streams of (1) General Trash, (2) Commingled Recyclables (plastics, cans, mixed paper), and (3) Organic Wastes. The PWS is an automated and sealed system with intake doors to compactor containers at each Central Waste Terminal. At the bottom of each inlet pipe are valve rooms where wastes are temporarily held - the system is not under continuous pressure. Once substantial waste has been collected in the valve chamber, or on a scheduled run, the waste bags are pneumatically sent direct to the respective compactor container for each waste type.

There will be additional specialty wastes, including glass, cardboard, non -hazardous recyclables, and hazardous wastes, are collected in smaller bins in the PWS intake rooms on each floor and taken manually to collection rooms at the basement level by environmental / janitorial services. Finally, there will be specific trash rooms on basement level accessible specifically by residents for bulk and specialty wastes. The specialty wastes are put into towable collection carts for semi - automated transport by tug to staging area under each CWT, and then manually taken to staging rooms/areas on both the Basement Level and First Floor soiled dock.

For wastes staged in basement trash rooms, a Tug system will take towable carts from the Trash Rooms to staging area under each CWT, and then manually taken to staging rooms/areas on both the Basement Level and First Floor soiled dock. Principle waste types, including (1) General Trash, (2) Commingled Recyclables, (3) Organics, and (4) Cardboard will be taken to compactor containers at each respective CWT and put into hopper for compaction. 1.6 WASTE GENERATION ESTIMATE See Tables 1 and 2 for the estimated volumes of general trash, recyclables, hazardous and other specialty wastes that will be generated from residents and commercial facilities of retail and offices. The provided estimate is utilized as basis for waste area design and equipment/system planning. Actual waste diversion to landfill can increase/decrease based on the goals and effectiveness to carry out recycling programs by facility management and individual tenants and residents. Total expected waste volume to be generated is estimated to be 1,714 cubic yards per week. Of this volume it is estimated for system planning that 1,089 cubic yards to be diverted on site from general landfill trash through recycling streams.
