C&D Diversion Report 

The City's Construction and Demolition (C&D) ordinance requires all applicable construction, renovation and demolition projects to divert at least 50% of C&D waste from the landfill through recycling, reuse and/or waste reduction. C&D waste material include metal, glass, brick, concrete, asphalt, pipe, gypsum, wallboard, lumber, rocks, soil, trees etc. 

The City of Davis has adopted Tier 1 of the California Green Building Standards Code (CALGreen), which encompasses a number of measures intended to conserve resources and reduce greenhouse gas emissions. Through CalGreen, the City requires applicable projects to divert at least 65% of all construction and demolition (C&D) debris to recycling or salvage.  C&D debris includes metal, brick, concrete, asphalt, pipe, gypsum, wallboard, lumber, etc. C&D debris does NOT include excavated soil and land clearing debris: trees, stumps, rocks and associated vegetation and soils resulting primarily from land clearing.

Does my project fall under the the CalGreen diversion requirements?

Residential projects that are required to follow the CalGreen diversion requirements include:

  • All new residential construction projects All residential demolition projects
  • All additions and alterations.

Applicable residential projects must:

  • Divert 65% of their C&D debris.
  • Submit a C&D Diversion Plan to the City showing how the project will meet diversion requirements.

Non-residential projects that are required to follow the CalGreen diversion requirements include:

  • All new construction projects
  • All demolition projects
  • All additions and alterations.

Applicable non-residential projects must:

  • Divert 65% of their C&D debris.
  • Divert 100% of their excavated soil and land clearing debris.
  • Submit a C&D Diversion Plan to the City showing how the project will meet diversion requirements.

If your project falls under the CalGreen diversion requirements, you are required to submit a Construction & Demolition Diversion Plan (C&D Diversion Plan).

What is a C&D Diversion Plan?

If your project falls under the CalGreen diversion requirements, you must fill c-and-d-material-lumberout and return a C&D Diversion Plan to the Community Development and Sustainability Department showing how you will divert 50% of the waste generated from your project. C&D Diversion Plan forms can be obtained from the Community Development and Sustainability Department when applying for a building or demolition permit, or can be downloaded online.

C&D Diversion Plan must be submitted before a building permit will be issued.

If it is determined that the C&D Diversion Plan is incomplete it will be returned to the applicant. The applicant will be required to submit additional information before the building or demolition permit is issued. A single plan may be used for multiple building permits where construction activities are occurring concurrently by the same applicant. Separate C&D Diversion Plans must be submitted for each batch of building permits requested. Separate calculations, plans and reports are required for the construction portion and demolition portion of projects.

For all projects where the waste hauler is Davis Waste Removal, only the C&D Diversion Plan must be submitted—no additional forms will be required. Davis Waste Removal (DWR) will haul all C&D waste to the sorting facility at the Yolo County Central Landfill and will provide all appropriate information directly to the City.

What if I want to self-haul?

DWR is the City’s franchise waste hauler. If you choose not to use DWR c-and-d-material-concreteto haul your C&D materials, then you are responsible for hauling your own materials. This means that you or your employees are solely responsible for the collection and transport of your waste. Per City Code, you cannot hire anyone or any other entity besides DWR to haul your waste. This restriction does not limit your ability to sell or donate separated C&D materials (such as wood, door knobs, scrap metal, etc.) for reuse or recycling, as long as the entity accepting your material does not require you to pay a monetary or non-monetary consideration for the collection, transportation, transfer, or processing of your materials (City Municipal Code 32.01.030).

If you decide to self-haul C&D waste instead of using DWR, you are required to submit proof of compliance to the Community Development and Sustainability Department before final inspection.

Proof of compliance includes:

  1. C&D Diversion Report Form.
  2. Receipts from the vendor/facility which collected or received each material showing the actual weight of that material (recyclables and trash).*
  3. Weight slips/count of material salvaged or reused in current project.*
  4. Any additional information needed to support a good faith effort determination.

*Each receipt/weight slip must clearly state the project title and date. If the receipt provides information for multiple projects, the project titles and the amounts of material for each project must be clearly identified.

These must be submitted along with a C&D Diversion Report Form to the Community Development Department BEFORE your final inspection in order to get your permit signed off. Failure to do so may result in fines.

How does the City determine if a project has complied with the C&D diversion requirements?

c-and-d-material-circular-sawFor all projects where Davis Waste Removal is the waste hauler, 50% compliance is automatically assumed.

On “self haul” projects the Public Works Department will review the C&D Diversion Report Form to determine whether the applicant has complied with the diversion requirement, as follows:

  1. Full Compliance: The project has met the diversion requirement.
  2. Good Faith Effort to Comply: The project did not meet the diversion requirement, but the applicant has made a good faith effort to comply.
  3. Non-Compliance: The project did not meet the diversion requirement and the applicant has not made a good faith effort to comply. A $1,000 penalty for non-compliance may be assessed.

How can I reuse and/or recycle C&D materials from my project?

If you decide to self-haul, there are several ways to get your diversion credit.

The Yolo County Central Landfill has a sorting facility that will take mixed C&D debris, sort it and guarantee a 50% recycling rate. Taking C&D debris to the sorting facility may be the easiest way for self-haulers to meet diversion requirements. Information about the C&D sorting facility at the landfill can be found on the Yolo County Central Landfill website. Click here for a list of items accepted as mixed C&D debris at the Yolo landfill C&D sorting facility.

Materials can also be sorted out by type and recycled or reused to get diversion credit. Below is a listing of some common materials and how to re-use or recycle them:

The Yolo County Central Landfill accepts reusable building materials for free. All donations are subject to inspection and may be rejected for donation. Example of acceptable items include: Lumber (Clean Wood 2”x4”s and 4”x4”s), Doors and Screens, Windows (Double Paned, Vinyl), Flooring (including tile and hardwood), Lighting Fixtures, Lamps and Fans Bricks and Pavers (no dirt, no sod, no rocks or soil), Cabinetry and Countertops (doors/drawers must be in tact), Tools, and Hardware (including plumbing fixtures). The landfill may refuse any donation at their discretion. Bring reusable items to the scale house at the landfill during normal operating hours. Reusable items will be sent to the Big Blue Recycling Barn Thrift Store at the landfill. See YoloCounty.org/Landfill for details.

Unwanted construction materials can be listed in the “free section” of the Davis Enterprise. Another free listing is CALMAX (California Materials Exchange). This service helps businesses find markets for materials they have traditionally discarded. Call CALMAX at 1-877-520-9703 or visit the CALMAX webpage.

The City of Davis Recyclopedia lists over 250 different items and how to reuse and recycle them locally.

Are there any exemptions from the C&D diversion requirement?

There are specific exemptions from the C&D ordinance for construction and demolition work that is done in conjunction with an emergency or a building/structure deemed substandard by the California Building Code through the Chief Building Official. Exemptions are also allowed for projects contaminated by hazardous substances or waste (as defined by state or federal law).
