Construction Waste Management Plan (CWMP)

Construction Waste Management Plan (CWMP)


California’s Green Building Standards Code (CALGreen) requires the diversion of at least 65 percent of the construction waste generated during most “new construction” projects (CALGreen Sections 4.408 and 5.408). 

As part of our commitment to complying with the CALGreen requirements, the City of Lakeport requires that all applicants submit a Construction & Demolition Waste Management Plan for each project that will generate waste or unused materials at its conclusion. The Purpose is to comply with State Law by diverting a minimum of 65% of non-hazardous debris from landfills. Per the current CAL Green Code, at least 65% of construction and demolition (C&D) materials must be diverted away from the landfill by either recycling or reusing materials.

SthYXVIRE7Jeparate CDWMP’s must be completed for demolition and construction at the same site, if separate permits are required.

Your CDWMP will identify the applicable material types and the actions that will be taken to divert construction and demolition debris from landfills.

NOTICE: Applicant (Contractors and sub-contractors) shall comply with the project’s CDWMP. It is the Applicant’s responsibility to collect all receipts from the facilities that recycle their materials AND all project waste/landfill disposal receipts. When working with the City Approved Facilities, C & S Solutions, Lakeport Disposal and Quackenbush, one cumulative project receipt is acceptable. However, it is the Applicant’s responsibility to confirm that the bins are collected.

C&D Management Options

There are several management options to choose from that will aid in recycling or salvaging 65% of material generated at a jobsite.
1.       Deconstruct all or part of a demolition and reuse the materials.
2.       Use one bin for all materials and take it to a mixed waste facility that diverts 65% or more of mixed C & D loads.
3.       Put each type of material in a separate bin and take it to a facility that diverts each material.
4.       Disposal, which does not provide any diversion credit and may be the same cost as the diversion alternatives listed.

Many facilities that process mixed waste are also disposal facilities so be sure to tell them you want it diverted. Often the price is the same. If you choose to use a debris box company to haul your material, you will have to tell the debris box company where you want the material taken or they may take it for disposal. Be sure to get receipts for all materials diverted and disposed.


Before issuance of a building, grading, or demolition permit for a covered project, a CDWMP must be approved by the City.
1.       The applicant must complete, sign and submit to the City the attached CDWMP application (PART 1).
2.       The City’s staff will review the submitted CDWMP. If the Chief Building Official determines that the CDWMP is complete and indicates that at least 65% of the C&D debris will be diverted, the CDWMP will be approved and a copy returned to the applicant.
3.       Prior to the final building inspection for the project, a Debris Recycling Report (PART 2) must be filled out and submitted to the building division. The report must include the approved CDWMP for the project, actual receipts and weight tags (summaries or invoices are not acceptable) from all disposal and recycling facilities and/or vendors that received each type of material showing if the material was land filled or diverted. Receipts should contain the date, job address or permit number, material type, disposition of material (reused, recycled, or landfilled), and the weight of the material.
4.       The Chief Building Official will review the Debris Recycling Report (PART 2) and determine whether the applicant has complied with the diversion requirement. If it is determined that the applicant has complied with the diversion requirement, the copy will be attached to the permit file, and the permit be finaled.

CalRecycle has created a very helpful website that includes a lot of great information and resources related to Construction and Debris Recycling. We encourage anyone responsible for preparing a CDWMP to check it out along with CalRecycle's Frequently Asked Questions page. The FAQ page includes questions frequently asked by stake holders involved in the C&D diversion process (e.g. cities, counties, contractors, recyclers, etc).
