Editor's note— Ord. 2000-332, § 1, adopted in 2000, enacted provisions to be incorporated as chapter 8.10. Inasmuch as chapter 8.10 already exists, said provisions have been redesignated as chapter 8.09, §§ 8.09.010—8.09.120, at the discretion of the editor.
8.09.010 - Findings and purpose¶
A. The town council finds that the state of California through its California Waste Management Act of 1989, Assembly Bill 939 (AB 939), requires that each local jurisdiction in the state divert fifty percent of solid waste from landfill by December 31, 2000, through source reduction, recycling, and composting activities.
B. The town council finds that the California Green Building Standards Code (CALGreen) includes new provisions effective January 1, 2017 that increase the required diversion rate to sixty-five percent.
C. The town council finds that with Assembly Bill 341 (AB 341) the state of California made a legislative declaration in regard to AB 939 that it is the policy goal of the state that not less than seventy-five percent of solid waste generated be source reduced, recycled, or composted by the year 2020.
D. The town council finds that every city and county in California could face fines up to ten thousand dollars a day for not meeting the above-mandated goal.
E. The town council finds and determines that the town is committed to protecting the public health, safety, welfare and environment.
F. In order to meet these goals, it is necessary that the town promote the reduction of solid waste and reduce the stream of solid waste going to landfills.
G. Debris from demolition and construction of buildings represents a significant portion of the volume presently going to landfill(s) from Portola Valley and much of said debris is particularly suitable for recycling.
H. The town council finds that reuse and recycling of certain portions of construction and demolition debris is essential to further the town's efforts to reduce solid waste, to comply with AB 939 mandates and the 2016 California Green Building Standards Code, and to work toward AB 341 mandates.
I. The town council finds that, except in unusual circumstances, it is feasible to divert an average of at least seventy-five percent of all construction and demolition debris from construction, demolition and renovation covered projects.
J. The town council recognizes that requiring construction and demolition debris to be recycled and reused may in some respects add modestly to the cost of demolition and in other respects may make possible some cost recovery and cost reduction.
K. It is necessary in order to protect the public's health, safety and welfare, that the following regulations be adopted.

(Ord. 2017-415, § 2, 2017; Ord. 2000-332 § 1 (part), 2000; Ord. 2002-340 § 1 (part), 2002)
8.09.030 - Deconstruction and salvage and recovery.¶
Every covered project shall be made available for deconstruction, salvage, and recovery prior to demolition. It shall be the responsibility of the applicant to recover the maximum feasible amount of salvageable designated recyclable and reusable materials prior to demolition. In order to provide sufficient time for deconstruction and salvage and recovery to be undertaken, no demolition may commence until a period of five working days has elapsed from the date of issuance of the demolition permit. Recovered and salvaged designated recyclable and reusable material from the covered project shall qualify to be counted in meeting the diversion requirements of this chapter. Recovered or salvaged designated recyclable and reusable materials may be given away or sold on the premises, or may be removed to reuse warehouse facilities for storage or sale.
(Ord. 2000-332 § 1 (part), 2000)
8.09.040 - Diversion requirements.¶
It is required that at least seventy-five percent of the waste tonnage of construction and demolition debris generated from every covered project shall be diverted from landfill by using recycling, salvage for reuse and diversion programs:
Notwithstanding, should town staff determine that more than twenty-five percent of project debris primarily consists of non-recyclable material and that the applicant has made a good faith attempt to meet, but cannot meet the seventy-five percent diversion requirement, town staff may grant an exception from the diversion requirements for the non-recyclable material only as long as all of the recyclable material is one hundred percent diverted.
In those cases where town staff has determined that the applicant has made a good faith effort to recycle or reuse the material and no recycling or reuse market may be found for that certain material, then alternative daily cover (ADC) may be considered as bona fide diversion for the materials for which there is no recycling or reuse market.
The town believes in the highest and best use of materials that are recycled. Therefore, ADC alone shall not count towards reaching the required diversion percentage.
(Ord. 2017-415, § 3, 2017; Ord. 2000-332 § 1 (part), 2000; Ord. 2001-335 § 1 (part), 2001; Ord. 2002-340 § 2 (part), 2002)
8.09.050 - Information required before issuance of demolition and/or building permit.¶
Every applicant shall submit a properly completed waste management plan, in a form as prescribed by the WMP compliance official to the WMP compliance official, as a portion of the building or demolition permit process and shall be in conformance with items 1. through 8., below. The completed WMP shall be updated as necessary and shall be available during construction for examination by the enforcing agency indicate all of the following:
Identify the construction and demolition waste materials to be diverted from disposal by efficient usage, recycling, reuse on the project or salvage for future reuse or sale.
Calculate the estimated volume or weight of construction and demolition waste materials, by material type, to be generated;
Identify the maximum volume or weight of such materials that can feasibly be diverted via reuse or recycling;
Identify the estimated volume or weight of construction and demolition debris that will be land filled;
Specify if construction and demolition waste materials will be sorted on-site (source-separated) or bulk mixed (single stream);
Identify the vendor that the applicant proposes to use to haul the materials, the facility to which the materials will be hauled, and the facility's requirement for diversion of the materials; and
Identify construction methods employed to reduce the amount of construction and demolition waste generated.
Calculate the total diversion rate of all materials at the end of the project.
In estimating the volume or weight of materials identified in the WMP, the applicant shall use the standardized conversion rates approved by the town for this purpose. Approval of the form as complete and accurate shall be a condition precedent to issuance of any building or demolition permit. If the maximum volume or weight of such materials that can feasibly be diverted via reuse or recycling, as estimated pursuant to item 3. above, is less than the required diversion requirements, applicant must submit information that supports the lower projected diversion rate, or the WMP shall be considered to be incomplete.
(Ord. 2017-415 § 4, 2017; Ord. 2000-332 § 1 (part), 2000; Ord. 2002-340 § 3 (part), 2002)
8.09.060 - Deposit required.¶
As a condition precedent to issuance of any permit for a construction or building for a covered project, the applicant shall post a cash deposit in the amount of fifty dollars for each estimated ton of demolition debris from a covered demolition or renovation project, and one-half percent of total project valuation for new construction projects, but not less than one thousand dollars (the deposit). Soil debris shall be treated in the manner as any other debris, unless the applicant has more than one hundred tons of soil debris in which case the total deposit for the soil debris shall be capped at five thousand dollars. The deposit shall be returned, without interest, in total or pro rated, upon proof to the satisfaction of the WMP compliance official that no less than the required percentages of the waste tonnage of construction and demolition debris generated by the covered project have been diverted from landfills and have been recycled or reused or stored for later reuse or recycling. If a lesser percentage of waste tonnage of construction and demolition debris than required is diverted, a proportionate share of the deposit will be returned. The deposit shall be forfeited entirely or to the pro rated extent that there is a failure to comply with the requirements of this chapter. The town council may, by formal resolution, modify the amount of the required deposit.
(Ord. 2000-332 § 1 (part), 2000; Ord. 2001-335 § 2 (part), 2001; Ord. 2002-340 § 4 (part), 2002)
8.09.070 - Administrative fee.¶
As a condition precedent to issuance of any permit for construction or demolition for a covered project, the applicant shall pay to the town a cash fee sufficient to compensate the town for all expenses incurred in administering the permit. The amount of the fee shall be determined in accordance with the then current fee schedule adopted by resolution of the town council.
(Ord. 2017-415 § 5, 2017; Ord. 2000-332 § 1 (part), 2000)
8.09.080 - On-Site practices.¶
During the term of the covered project, the applicant shall recycle or reuse the required percentages of materials, and keep records of the tonnage or the other measurements approved by the WMP compliance official that can be converted to tonnage. The WMP compliance official will evaluate and monitor each covered project to gauge the percentage of materials recycled, salvaged and recycled or reused from the covered project. The required diversion of a minimum of the required percentages of the designated recyclable and reusable materials shall be measured separately with respect to the demolition segment and the construction segment of a covered project where both construction and demolition are involved. To the maximum extent feasible, each of the seven categories of designated recyclable and reusable materials, as set forth in 8.09.020 [K], shall be separated on-site, and separately transported to a processor, in order to permit maximum diversion. For deconstruction and/or demolition projects, on-site separation shall include salvageable materials (appliances, fixtures, plumbing, etc.,) and dimensional lumber. For all other construction projects on-site separation shall include dimensional lumber, wallboard and cardboard.
(Ord. 2000-332 § 1 (part), 2000)
8.09.090 - Reporting.¶
Within sixty days following the completion of the demolition phase of a covered project, and again within sixty days following the completion of the construction phase of a covered project, the applicant shall, as a condition precedent to final inspection and to issuance of any certificate of occupancy, submit documentation to the WMP compliance official which proves compliance with the requirements of Sections 8.09.030 and 8.09.040. The documentation shall consist of a final completed "Waste Management Plan" showing actual data of waste tonnage, supported by originals or certified photocopies of receipts and weight tags or other records of measurement from recycling companies, deconstruction contractors, and/or landfill and disposal companies. Receipts and weight tags will be used to verify whether materials generated from the site have been or are to be recycled, reused, salvaged or otherwise disposed of. The applicant shall make reasonable efforts to ensure that all designated recyclable and reuse materials salvaged or landfilled are measured and recorded using the most accurate method of measurement available. To the extent practical, all construction and demolition debris shall be weighed by measurement on scales. Such scales shall be in compliance with all regulatory requirements for accuracy and maintenance. For construction and demolition debris for which weighing is not practical due to small size or other considerations, a volumetric measurement shall be used. For conversion of volumetric measurements to weight, the applicant shall use the standardized conversion rates approved by the town for this purpose.
If a covered project involves both demolition and construction, the report and documentation for the demolition project must be submitted and approved by the WMP compliance official before issuance of a building permit for the construction phase of a covered project. In the alternative, the applicant may submit a letter stating that no waste or recyclable materials were generated from the covered project, in which case this statement shall be subject to verification by the WMP compliance official. Any deposit posted pursuant to Section 8.05.050, shall be forfeited if the applicant does not meet the timely reporting requirements of this section.
(Ord. 2000-332 § 1 (part), 2000)
8.09.100 - Violation a public nuisance.¶

(Ord. 2000-332 § 1 (part), 2000)
8.09.110 - Penalties.¶
Each violation of the provisions of this chapter shall constitute a misdemeanor, and shall be punishable by imprisonment in the county jail for not to exceed six months, or by fine not exceeding one thousand dollars, or by both such fine and imprisonment. Each day that a violation continues shall be deemed a new and separate offense.
(Ord. 2000-332 § 1 (part), 2000)
