1. Why does the CRV fee exist?

The beverage container recycling program began in California in 1987 as a way to assure the return for recycling of a greater percentage of the beverage containers sold in the state. It is estimated that more than 300 billion aluminum,  glass, and plastic beverage containers have been recycled since.

2. Are there beverages are excluded from the CRV program?

Any product sold in a container that is not aluminum, glass, plastic, or bimetal is excluded from CRV. These include:

• Milk
• Medical food
• Infant formula
• Vegetable juice in containers 16 ounces or greater in volume
• 100 percent fruit juice in containers 46 ounces or greater in volume
• Distilled spirits
• Wine, or wine from which alcohol has been removed, in whole or in part, whether or not sparkling or carbonated.

3. What is a recycling center?

A recycling center is an operation certified by the Department to accept empty beverage containers and pay CRV to consumers. Recycling centers are operated by independent businesses, not the State of California.

4. How much do recycling centers pay per pound for cans and bottles?

Currently, state certified recycling centers pay a minimum of $1.65 CRV for aluminum cans; $1.31 CRV for clear PET plastic bottles; $0.58 CRV for HDPE plastic bottles (similar to the large water jugs); and $0.10 CRV for glass bottles. These CRV per pound rates are periodically adjusted, with new rates taking effect January 1 and July 1.

5. Can recycling centers pay less than the refund value for redeemed containers?

Yes, if the material is contaminated. Operators of certified recycling centers must inspect each load of containers to determine whether it is eligible for CRV. Recycling centers have the option to refuse to accept containers which, in their opinion, are excessively contaminated with dirt, moisture, or other foreign substances.

1. What is the California Voting Rights Act (CVRA)?

In 2001, the state legislature approved the California Voting Rights Act (CVRA), modifying burden of proof requirements contained in the federal Voting Rights Act of 1965 to make it easier for plaintiffs to challenge at-large voting systems. Federal protected classes include members of the same race, color, national origin, religion, sex/gender, age (over 40), and disability. The CVRA prohibits an agency from using at-large elections if it impairs the ability of a protected class to elect candidates of its choice or otherwise influence the outcome of an election. The CVRA includes the imposition of district-based elections by a court as a remedy to violations of the Act, and requires the government agency to pay all legal and court fees of a plaintiff that prevails in the courts.

2. What is racially polarized voting?

A violation of the CVRA is established if it is shown that racially polarized voting occurred in City Council elections or in the election of candidates for other offices by the voters. Racially polarized voting occurs when there is a difference in the choice of candidates that are preferred by voters in a protected class versus the choice of candidates preferred by voters in the rest of the electorate.

3. What are district-based elections?

Since incorporation in 1989, the City has used an “at-large” election system in which voters elect each of the five City Council Members to provide city-wide representation. A district-based election system is one in which the city is divided into geographic districts where voters in each district select one Council Member who resides in that district to represent them.

4. Will the change to a district-based election system affect my vote?

Yes.  Instead of voting for all five members of the City Council, voters will vote for the one member only.

5. Why is the city moving to district-based elections?

In a letter received January 13, 2022, Mr. Kevin Shenkman, counsel representing the Southwest Voter Registration Education Project (SVREP), alleged that the City’s at-large elections system violates the CVRA because it results in racially polarized voting that dilutes the impact of Latino voters. The letter demands that Diamond Bar voluntarily change its at-large system for electing City Council members to a district-based system to avoid litigation.

To succeed in the courts, a plaintiff must only show that racially polarized voting has occurred. To date, there is no established CVRA case law in which a public agency defendant has successfully prevailed on the merits. Thus, the majority of cities facing the threat of CVRA litigation have voluntarily transitioned to district-based elections citing the cost of legal defense and potential liability for significant attorney’s fees and settlement costs that have reached into the millions of dollars if the City’s legal defense is unsuccessful.

On February 17, 2022, the Diamond Bar City Council adopted a resolution stating its intent to voluntarily transition to district-based elections.

6. What is the timeline to move to district-based elections?

In 2016, the legislature amended Elections Code section 10010 to create a limited “safe harbor” timeline for agencies to transition from at-large to district elections. The amendment prevents a CVRA lawsuit from being filed if the agency adopts a Resolution of Intent to transition to district-based elections within 45 days of receiving a letter from a potential plaintiff. The agency then has 90 days to complete legal proceedings to make the transition. If all required actions are completed within the timeline, the agency’s potential liability for plaintiff’s attorney’s fees is capped at $30,000.

To transition to a district-based system, the City Council must adopt an ordinance requiring City Council members to be elected by district or by district with an elected mayor pursuant to Government Code section 34886. Per Government Code section 34886, the ordinance does not need to be submitted to the voters for approval, but must include a declaration that the change in election procedures is being made to further the purposes of the CVRA. Prior to the adoption of the ordinance, the City Council must establish district boundaries and determine which of the new districts will be subject to the first district elections. To do so, a minimum of five public hearings must be scheduled, as follows:

• A minimum of two public hearings at which the public can provide input on district boundaries before draft district maps are prepared. These public hearings are currently scheduled for March 1, 2022 and March 15, 2022.
• A minimum of two public hearings to consider draft district maps.  The public hearings are currently scheduled for April 5, 2022 and April 19, 2022.
• A public hearing to adopt the district map and establish the sequence of elections. In addition to the preferences expressed by residents of the districts, the maps must include consideration of natural geographic boundaries, communities of interest, and the “one person, one vote” standard, which requires all districts to be as nearly equal in population as possible. Federal case law prohibits districts from being drawn with race as a predominate factor. This public hearing is currently scheduled for May 3, 2022.

7. Why is this happening so fast? Can we slow down the process?

The “safe harbor” provisions of the Elections Code set strict, defined timelines. The City cannot deviate from the 90-day safe harbor timeline explained in the previous question without exposure to litigation and potentially significant costs.

3. When and why do I need a building permit?

If you are planning renovations or new construction in or around your property, chances are you will need to obtain a building permit. Taking out a permit before commencing your construction project not only keeps you in compliance with City law, but also protects you and your investment - be it a home or a business. For more information, contact the Building and Safety Division.

4. What are the rules for storage on my property?

The Neighborhood Improvement Officers enforce all City Municipal Codes applicable in the community, including the provision against the open storage of junk. This code states that front and side yards shall be kept and maintained free and clear of:

• Appliances
• Camper Shells
• Construction and automotive materials or parts
• Discarded or Broken Materials
• Equipment
• Furniture
• Inoperative Motor Vehicles
• Junk
• Trash, Refuse, and Debris

If a property is found not in compliance with the code, a notice of violation is sent to the owner allowing a certain number of days to correct the violation. If a violation is not corrected within the time allowed, the owner may be fined. Any debris that is found, which is associated with the code violation, may be removed by a contractor at the property owner's expense. Failure to pay the fine will result in a lien being placed against the property. For more information, call 909-839-7030 or submit a request. 

5. How long may holiday lights be displayed?

The City's Municipal Code states that exterior holiday lights and decorations must be removed within 30 days of installation, and no later than mid January. Besides contributing to blight, keeping holiday lights installed for an extended period of time creates the potential for a fire hazard because of their temporary-use nature. Homeowners found not to be in compliance will be issued a courtesy notice to correct violation within 10 days. Failing to remove the lights within the allotted time frame can result in a $100 fine.

6. Is there a regulation against storing inoperative motor vehicles?

Yes. All vehicles that are being repaired, dismantled, or incapable of operating are considered "inoperable" and must be stored out of public view, such as in the garage, when possible. It is considered a violation of the City Code if the vehicle or its parts become a hazard to the public health and safety. To report, contact the Neighborhood Improvement Division at 909-839-7030.

7. I want to build an Accessory Dwelling Unit (ADU) on my property. What are the requirements and process?

A JADU is created within the walls of a single-family residence and may share central systems and restrooms with the primary residence, and must contain a basic kitchen. JADUs are allowed up to 500 square feet. Refer to the Development Code Section 22.42.120 for additional ADU requirements - https://library.municode.com/ca/diamond_bar/codes/code_of_ordinances?nodeId=CICO_TIT22DECO_ARTIIISIPLGEDEST_CH22.42STSPLAUS_S22.42.110REACUSST.

 Once you have plans ready, you may submit through the Planning inquiry form. No additional forms are required at this stage. Please allow a few days for the Planning and Building and Safety Divisions to review for completeness. Once authorization is received, a planner will instruct you on the next steps for formal building plan check submittal to the Building and Safety Division. There is a 15-working day turnaround once accepted by the Building and Safety Division. Every subsequent submittal is 10 working days. When all comments/corrections have been addressed, your permit will be issued for the ADU.

8. Are short-term rentals allowed?

Short-term rentals, such as those listed on Airbnb and similar sites, are prohibited in all residential zones within Diamond Bar.  The Diamond Bar Municipal Code defines a hotel or motel as “facilities with guest rooms or suites, provided with or without kitchen facilities, rented to the general public for transient lodging (less than 30 days).” By definition, a residence being rented to a tenant for fewer than 30 days is, therefore, classified as a hotel/motel, and is not a permissible use in residential zones pursuant to the City’s land use table. For more information, refer to Sec. 22.08.030. and Sec. 22.80.020. of the Diamond Bar Municipal Code.

9. What is the Diamond Bar Zoning Map, and how can I see a copy?

The Diamond Bar Zoning Map designates existing land use classifications for each parcel located within the city. In addition to land use types (residential, commercial, and open space/conservation), the map also indicates the density of housing development allowed such as Low Medium Density Residential (RLM), Medium High Density Residential (RMH), and High Density Residential (RH). The Zoning Map is available online as part of the City’s GIS mapping database.

1. What is a Housing Element?

State law[1] requires each city to adopt a comprehensive, long-term General Plan for its physical development. General Plans include several “elements” that address various topics. The Diamond Bar General Plan[2] was comprehensively updated in 2019 and includes the following elements:

• Land Use and Economic Development
• Community Character and Place Making
• Circulation
• Resource Conservation
• Public Facilities and Services
• Public Safety
• Community Health and Sustainability
• Housing[3]

While most portions of General Plans typically have a time horizon of 20-25 years, State law requires that the Housing Element be updated in 8-year “cycles.” The City is currently preparing a Housing Element update for the 2021 to 2029 planning period, which is referred to as the “6th Housing Element cycle” in reference to the six required updates that have occurred since the comprehensive revision to State Housing Element law in 1980.

------------------------------------

[1] California Government Code Sec. 65300 et seq.

[2] http://www.diamondbargp.com/

[3] The Housing Element was last updated in 2014 and was not part of the 2019 General Plan update

2. What is Housing Element “certification” and why is it important?

The State Legislature has delegated to the California Department of Housing and Community Development (“HCD”) the authority to review Housing Elements and issue findings regarding the elements’ compliance with the law.[1] When HCD issues a letter finding that the Housing Element is in substantial compliance with State law it is referred to as “certification” of the Housing Element.

Housing Element certification is important for two main reasons:

• Local control. The General Plan and its various elements provide the foundation for the City’s land use plans and development regulations, and the Housing Element is part of the General Plan. If the City were challenged in court on a planning or zoning matter and the General Plan were found by the court to be invalid, the court could order changes to City land use plans or regulations and assume control over City land use decisions. HCD certification establishes a “rebuttable presumption of validity”[2] that the Housing Element complies with State law, which would support the City’s legal defense. Recent laws also allow for courts to impose fines on a jurisdiction if it fails to adopt a Housing Element in compliance with State law.[3]
• Eligibility for grant funds. Some State grant funds are contingent upon Housing Element certification. Grants can help to cover the cost of some projects that would otherwise rely on the City’s General Fund.

3. What are the most important issues that must be addressed in the Housing Element?

The major issues that must be addressed in the Housing Element are: 1) how City policies, plans and regulations help to meet the region’s housing needs for persons and families of all income levels; and 2) how City land use regulations accommodate the special housing needs of those with disabilities or other difficulties.

• Accommodating Regional Housing Needs. Under State law[1] all cities are required to plan for additional housing to accommodate population growth and address existing housing problems such as overcrowding and high housing cost. State law recognizes that cities generally do not build housing, since that is typically the role of private and non-profit developers and builders. However, cities are required to adopt policies, development regulations and standards to encourage a variety of housing types that are affordable for persons of all income levels, such as rental apartments and accessory dwelling units (“ADUs”). The Regional Housing Needs Assessment (“RHNA”) is the method by which each jurisdiction’s share of new housing needs is determined (see #5 below)
• Housing for Persons with Special Needs. Under State law[2] cities must also ensure that their plans and regulations encourage the provision of housing for persons with special needs including:

• Reasonable accommodation for persons with disabilities

• Transitional housing

• Supportive housing

• Emergency shelters and other facilities serving the homeless

• Large (5+) families

-----

[1] California Government Code Sec. 65583

[2] California Government Code Sec. 65583(a)(5)

4. What is “affordable” housing?

By definition, housing is considered “affordable” when total housing cost, including utilities, is no more than 30% of a family’s gross income. State law describes five income categories, which are based on county median income as shown in Table 1.

Table 1. Household Income Categories
Income Category	% of county median income
Extremely low	Up to 30%
Very low	31-50%
Low	51-80%
Moderate	81-120%
Above moderate	Over 120%
Source: California Government Code Sec. 65584(f)

Affordable housing costs for all jurisdictions in Los Angeles County are determined based on these income categories as shown in Table 2. These incomes, rents and housing prices are based on a 4-person family and are adjusted for different family sizes.

Table 2. Income Categories and Affordable Housing Costs – Los Angeles County
Income Category	Maximum Income	Maximum Affordable Rent	Maximum Affordable Price (est.)
Extremely low	$33,800	$845	*
Very low	$56,300	$1,407	*
Low	$90,100	$2,252	*
Moderate	$92,750	$2,319	$375,000
Above moderate	Over $123,600	Over $3,090	Over $375,000
Assumptions: -Based on a family of 4 and 2020 State income limits -30% of gross income for rent or principal, interest, taxes & insurance plus utility allowance -10% down payment, 3.75% interest, 1.25% taxes & insurance, $300 HOA dues * For-sale affordable housing is typically at the moderate-income level Source: Cal. HCD; JHD Planning LLC

5. What is the “RHNA” why is it important?

Each California city is required to plan for new housing to accommodate a share of regional needs. The Regional Housing Needs Assessment (“RHNA”) is the process established in State law[1] by which housing needs are determined.

Prior to each planning cycle the total new housing need for each region of California is determined by HCD based upon economic and demographic trends, existing housing problems such as overcrowding and overpayment, and additional housing needed to ensure reasonable vacancy rates and replace units lost due to demolition or natural disasters.

Diamond Bar is located within the Southern California Association of Governments (“SCAG”) region, which includes Los Angeles, Orange, Riverside, San Bernardino, Imperial and Ventura counties. The total housing need for the SCAG region is distributed to cities and counties by SCAG based upon objectives and criteria established in State law.[2]

In 2019 HCD determined that the total new housing need for the entire SCAG region in the 6th Housing Element cycle is 1,341,827 units. SCAG is currently finalizing the RHNA plan for the 6th cycle, which must fully allocate the total RHNA to jurisdictions in the SCAG region.[3] SCAG expects to adopt the final RHNA plan by February 2021.

The RHNA also distributes each jurisdiction’s total housing need into four income categories (the extremely-low and very-low categories are combined for RHNA purposes). Diamond Bar’s preliminary 6th cycle RHNA allocation by income category is shown in Table 3.

Table 3. Draft 6th RHNA by Income Category – Diamond Bar

6. Is the RHNA a construction mandate?

The RHNA allocation identifies the amount of additional housing a jurisdiction would need in order to have enough housing at all price levels to fully accommodate its assigned share projected growth over the 8-year planning period. The RHNA is a planning requirement based upon housing need, not a construction quota or mandate. Jurisdictions are not required to build housing or issue permits to achieve their RHNA allocations, but some provisions of State law establish specific requirements when housing production falls short of RHNA allocations. One such requirement is streamlined review and approval of housing development applications that meet specific standards.[1] Other than requirements for streamlined permit processing, there are currently no legal or financial penalties imposed on cities for failing to achieve their RHNA allocations.

-----

[13] California Government Code Sec. 65913.4 (SB 35 of 2017)

7. What must cities do to comply with the RHNA?

The Housing Element must provide
an evaluation of the city’s capacity for additional housing based on land use
patterns, development regulations, other development constraints (such as
infrastructure availability and environmental conditions) and real estate
market trends. The analysis must be prepared at a parcel-specific level of
detail and identify properties (or “sites”) where additional housing could be
built consistent with City regulations. This evaluation is referred to as the
“sites analysis” and State law requires the analysis to demonstrate that the
city has adequate capacity to fully accommodate its RHNA allocation in each
income category. If the sites analysis does not demonstrate that adequate
capacity exists to fully accommodate the RHNA, the Housing Element must describe
what steps will be taken to increase capacity commensurate with the RHNA –
typically through amendments to land use and zoning regulations that could
facilitate additional housing development. Such amendments typically include
increasing the allowable residential density or allowing housing to be built in
areas that are currently restricted to only non-residential land uses.

Diamond Bar’s new General Plan,
adopted in December 2019, estimates that up to 3,750 new housing units could be
built in the city by 2040, depending on market conditions. It is expected that
much of this growth would occur within the Town Center Mixed Use, Neighborhood
Mixed Use, Transit Oriented Development and Community Core Overlay focus areas,
while most existing residential neighborhoods will experience less growth and
change. While the General Plan identifies potential for significantly more new
housing than the draft 6th RHNA allocation of 2,514 units, the
Housing Element must demonstrate that realistic capacity exists for the amount
of new housing in each income category to be built during the 2021-2029 planning
period based on zoning, site conditions and market trends. This analysis is
expected to be the primary focus of the Housing Element update.

8. Why are cities in high-cost areas expected to have affordable housing? Low-cost housing is not economically feasible here due to high land prices.

State housing laws are based on the premise that every city has an obligation to accommodate a range of housing types for persons at all income levels. Every community is dependent on a variety of low- and moderate-income workers in jobs such as landscaping, building maintenance, child and elder care, medical technicians, personal services, clerical support and retail trade. While the existing housing stock serves the needs of many residents, market rents and prices are higher than some families can afford. In addition, low-wage jobs have increased at a much faster rate than affordable housing is being built.

While cities are not required to build new housing, they must ensure that their land use regulations encourage a full range of housing types. Rental apartments typically provide the majority of affordable housing, but other types of housing such as accessory dwelling units[14] (ADUs) can also help to address this need. Various governmental programs provide funding assistance for affordable housing, but if a city’s development regulations are too restrictive, affordable housing may be infeasible and the housing needs of the local workforce will be shifted to other cities.

-----

[14] “Accessory dwelling unit” means an attached or a detached residential dwelling unit that provides complete independent living facilities for one or more persons and is located on a lot with a proposed or existing primary residence. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single-family or multifamily dwelling is or will be situated.

9. There is very little vacant land suitable for housing development left in Diamond Bar. Why is the RHNA allocation so high?

SCAG’s 6th cycle RHNA allocation for the entire 6-county region is 1,341,827 units compared to 412,137 units in the 5th cycle. There are two main reasons why the 6th RHNA allocation is so much higher than the 5th cycle.

First, the 5th cycle RHNA allocation was established in 2012 while the severe economic effects of the “Great Recession” were discouraging growth. As a result, the 5th RHNA was uncharacteristically low. For comparison, SCAG’s 4th cycle (2006-2013) RHNA allocation was approximately 700,000 housing units.

Second, for the 6th cycle the State made a major modification to the process for determining RHNA allocations. In prior RHNA cycles, total housing need was based only on projected population growth. However, for the 6th RHNA cycle the State added existing need to the total RHNA calculation. Existing need includes households that are currently overcrowded (defined as more than one person per room) or are overpaying for housing (defined as more than 30% of gross income).

The total 6th cycle RHNA allocation for the SCAG region is comprised of the sum of existing need and projected need, as follows:

Existing need: 577,422 units \ Projected need: 764,405 units

Total need: 1,341,827 units

As seen from this breakdown, if existing need were excluded (as was the case in prior RHNA cycles) the total need would be similar to the 4th cycle RHNA.

With regard to jurisdictional RHNA allocations, the methodology adopted by SCAG for the 6th cycle places greater emphasis on the proximity of jobs and public transit rather than vacant developable land. As a result, the urbanized areas of Los Angeles and Orange counties are assigned much higher housing need as compared to prior cycles even though they generally have much less vacant land than inland areas.

Diamond Bar’s RHNA allocation in the 5th cycle was 1,146 units; therefore, the draft 6th cycle allocation of 2,514 units is about 2.2 times the prior cycle. By comparison, SCAG’s total 6th RHNA allocation is 3.3 times the 5th cycle total.

Full-service restaurants are exempt if they they have wait staff and/or kitchen staff responsible for escorting diners to their table, taking their order, delivering their food to their table, bringing their bill or helping them process their payment, and clearing their table after they leave. Bins for employees to sort food waste must be labeled, visible, and readily accessible.

4. What are the AB 827 requirements?

Organic waste bins or containers must be visible and easily accessible to employees and customers, they must be labeled, and they must be placed adjacent to each trash can (restroom waste bins are excluded). There is no minimum number of bins required.

9. What can I do about overhanging branches from a neighbor’s tree?

By law, you have the right to trim tree branches that extend into your property line. However, it is good practice to bring up the issue with your neighbor first. Give them a chance to take care of the trimming themselves, and/or offer to do it if they prefer. 

Keep in mind that California has very strict laws regarding tree trimming. Under section 3346 of the California Civil Code, a person may not cut or remove any part of a tree that does not overhang their property. If you cause the tree to die or cause so much damage that its value is destroyed, you may be held financially responsible. Furthermore, certain trees such as the native oak, walnut, sycamore and willow are protected by Diamond Bar ordinance, even if they are on private property. If the pruning is extensive, you need to first obtain a permit. Refer to Chapter 22.38 of Diamond Bar Municipal Code for more information on tree preservation and protection.

1. Do I need a business license? How do I obtain one?

All businesses doing work within city limits, whether or not they have a physical address in the city, are required to have a business license, including out-of-city contractors and gardeners. Home-based businesses in Diamond Bar are also required to have a business license.

Before applying for a business license or signing a lease, please verify that a location of interest is zoned appropriately for your proposed business. For instructions on how to find a property’s zoning designation, refer to Question 2 or contact the Planning Division. Certain businesses will require other approvals such as a Conditional Use Permit (CUP) and/or background checks before a business license can be granted.

You may submit your business license application, along with payment, via mail, online, or in person by making an appointment with the Planning Division.

Once an application is received, a staff member will contact you if additional information is required; otherwise, the business license certificate and receipt will be sent to the email address provided on the application. Please allow a few days for processing.

A CUP is a special permit that allows a business or property owner to engage in a certain type of land use, so long as it complies with specific conditions.  When reviewing a CUP, consideration is given to the location, design, configuration, operational characteristics and potential impacts to determine whether or not the proposed use will pose a detriment to the public health, safety and welfare.  All CUP requests require a public hearing before the Planning Commission, which has the authority to approve or deny such requests. When a CUP is approved, it runs with the land and all conditions placed on the CUP are binding on all successors in interest.

1. What is Report for Reward?

Report for Reward is a City of Diamond Bar program that offers individuals financial incentive of up to $500 for providing information leading to the arrest of a person(s) who damaged property as a result of a realized (or attempted) residential or vehicular burglary within Diamond Bar city limits.

2. When was Report for Reward established?

Report for Reward was established on November 15, 2013 after being approved by the Diamond Bar City Council – by way of Ordinance No. 08(2013) – during its regular meeting of October 1, 2013.

3. Where can I find information about the ordinance related to this reward program?

Ordinance Number 08(2013) is now part of the Diamond Bar City Municipal Code – Chapter 9.02 entitled: “Reward for Crime Information.” The City’s Municipal Code is available for viewing online or in person at Diamond Bar City Hall during its regular business hours of Monday through Thursday 7:30 a.m. to 5:30 p.m., and Friday from 7:30 a.m. to 4:30 p.m.
