LAD No. 39

Benefit Assessment Districts: LAD No. 39

The Landscape Assessment District No. 39 (the “District”) ("LAD No. 39") was originally formed in 1985 to fund landscaping improvements and ongoing maintenance. The District funds the servicing and maintenance of various private properties to mitigate brush fire hazards and enhance the appeal of the entire community. The District also maintains five developer-created mini-parks and trails. While the assessment fee remained locked at its original amount during the past decades, maintenance costs continued to increase. This created a shortfall in funds between District assessments and maintenance costs. The City can no longer continue to subsidize what should be a self-supporting District. As a result, the City is looking to dissolve the current District and is working with CivicMic to determine stakeholder support for the replacement of LAD No. 39 with a new district that will generate enough funds to continue landscaping maintenance and improvements.

What are Benefit Assessment Districts?

Benefit assessment districts, like the LAD No. 39, are a special assessment or charge, collected typically on the property tax bill. They are used by local governmental agencies in California (counties, cities, and special districts) to fund public improvements and services. In other words, the charge only applies to properties receiving a benefit instead of being applied against all properties within a governmental jurisdiction, as is the case with regular property taxes.

What is Special Benefit?

Article XIII D of the California Constitution (commonly referred to as Proposition 218) defines special benefit as "a particular and distinct benefit over and above general benefits conferred on real property located in the district or to the public at large.  General enhancement of property value does not constitute 'special benefit.'"

There are a few helpful aspects worth considering:

  • A public improvement or service confers a benefit.  For example, street lighting is an improvement, not a special benefit.  However, street lighting confers a "safety" benefit to properties nearby and to non-residents driving through.
  • In this case, the safety benefit conferred to properties nearby is a special benefit, but the safety conferred on pass-through drivers is a general benefit.
  • The local agency is required to separate and quantify special and general benefits so that properties nearby the street lighting (in this example) are charged for just the special benefit portion.  The general benefit portion must be paid from other sources and can't be charged against the properties within the assessment district.
  • Note, an improvement or service like street lighting (in this example) can have multiple benefits identified, separated, and quantified.  Also, there are many other improvements and services that can be funded by an assessment district.  We have used a single benefit and improvement to simplify our illustration of this concept.

Why are Benefit Assessment Districts Formed?

Assessment districts ensure that constituents across town are not paying for improvements and services specific to neighborhoods miles away and vice versa.  It serves as a fair and direct mode of taxation, recognizing the variations in the type and levels of public improvements and services provided to each neighborhood.  It also provides a way for constituents to have a direct say in improving their neighborhoods by participating in the governance process and establishing their own neighborhood-specific assessment district.

Revenues collected through an assessment district are strictly limited for the improvements and services for which the assessment district was formed.  Furthermore, a district can't be formed without the participation of the property owners through a ballot procedure.  Meaning, a governmental agency can't establish a district and "tax" a neighborhood on its own.

In many ways, benefit assessment districts can be said to be comparable to a homeowner's association in the way that it funds facilities and work specific to a neighborhood from a direct and additional charge not paid by other neighborhoods in town.  The main differences are that the charge appears on the property tax bill and the work is managed by the local governmental agency.  Note that work can be performed by public employees of the agency and/or outsourced to private contractors and organizations.  Assessment districts can also have citizen advisory committees to help the agency annually establish levels of service, desired improvements and services, the budget, and corresponding rates.

Historical Context

Benefit assessment districts have been around for a long time.  California started using them in the early 1900s to pay for projects specific to small geographical areas.  Since then, the California legislature has enacted many Acts to facilitate the funding of many types of public improvements and services, but all are required to result in a charge that is proportional to the special benefit received by each property.

Where did the idea come from?  According to a California State Legislature Senate Governance & Finance Committee (2011) publication,

The landmark study, Windfalls for Wipeouts by Hagman and Misczynski, traced benefit assessments to a local 13th Century ordinance in England that used assessments to pay for repairs to seawalls.  Residents paid for the seawall repair in proportion to the amount of land protected by the seawall.  In 1691, the tradition of levying benefit assessments reached America: New York City assessments paid for paving streets and building a drainage system. (p. 5)

The Process of Forming or Replacing an Assessment District

The process required to establish benefit assessment districts vary slightly based on the specific and applicable legislative Act and applicability of the Act is dependent on the specific public improvements and services being funded but in general, the process includes:

  • Formal initiation of the formation process by the legislative body (Board of Supervisors, City Council, Board of Directors) based on a petition from the property owners and/or local officials.  We generally expect to see the following Resolutions enacted:
    • Resolution initiating proceedings to form the assessment district and ordering of the preparation of the assessment engineer's report.  The report separates and quantifies special and general benefits and provides a method of assessment with a proportional rate schedule.
    • Resolution of intent to form the assessment district, approving the report in draft form, ordering the mailing of notices and ballots to owners of property subject to the assessment, and setting the location, date, and time of the public hearing for the tabulation of ballots.
    • Resolution confirming the assessments, if results from the tabulation of ballots supports it, and the ordering of charges to be placed on the property tax bills.
  • Preparation of an assessment engineer's report.  The most critical piece of information for a constituent participating in the process.  The report separates and quantifies special and general benefits and provides a method of assessment with a proportional rate schedule showing the assessment charge against each property.
  • Notices and ballots are mailed to owners of property within the boundaries of the assessment district subject to the assessment charge.  Only properties receiving a special benefit will be charged the assessment.
  • A public hearing is held to allow all interested parties to speak to the legislative body about the proposed assessment district, the ballots are tabulated and results are announced.  An assessment district is approved by the property owners if the total assessment amount represented by the ballots received against the assessment does not exceed the total assessment amount represented by the ballots received in favor of the assessment.  In other words, ballots are weighted by the assessment amount assigned to each property.  The greater the assigned amount of the assessment, the greater the say in the results of the tabulation (only returned completed ballots are considered).
  • Assuming successful approval, assessments are added to the secured property tax bills for the term prescribed in the assessment engineer's report and resolutions described above.  Some assessments have a term and others can last in perpetuity.  Most assessments provide for an annual inflation factor to keep up with the ever-increasing costs of maintaining improvements and providing services.

LAD No. 39 and Benefit Assessment Districts

There are many communities in California using assessment districts successfully to fund improvements and services that enhance the lives of many thus improving neighborhoods with one of the most direct forms of self-taxation available.  Participation in the formation of an assessment district and the ongoing process of working with public officials to establish levels of service, budgets, and annual assessment charges by citizen advisory committee members can be very rewarding.  The goal of the CivicMic team is to assist public agencies by providing outreach and opportunities for the public to engage in a collaborative governance process.

  1. As of now where does District 39 stand in the process of voting to continue to have the City of Diamond Bar to maintain doing the maintenance? Will there be another vote to have the tax increased to maintain it? The voting a year ago, I don’t think we all fully understood what the amount increased was going to be.
    Thank you

    1. Hi Jonathan,

      As of now, the City is in the process of dissolving District 39 and establishing a new District (District 39-2022), which will need to be voted on by property owners within the district boundaries early next year. The purpose of the new district will be to generate enough revenue through assessments to sustain these services without the City having to subsidize them. The amounts haven’t been finalized yet. However, once they will be, we will post that information to CivicMic. You will also be able to see the new amounts on our web map when you click on the individual parcels. Here is the link to the web map:

      Hope this helps!
