Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
INTRODUCTION
Pursuant to the provisions of the Benefit Assessment Act of 1982, being Chapter 6.4 of the California Government Code, commencing with Section 54703 (hereafter referred to as the “1982 Act”), and in compliance with the substantive and procedural requirements of the California State Constitution Article XIIID (hereafter referred to as the “California Constitution”), the City Council of the City of Santa Clarita, County of Los Angeles, State of California (hereafter referred to as “City”), propose to form and levy special benefit assessments for the district to be designated as:
Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
(hereafter referred to as “D BAA”), which includes all lots and parcels of land within Tract No. 82126 that will receive special benefit from the drainage improvements installed and maintenance in connection with the development of these residential subdivisions within the City limits of Santa Clarita. This Engineer’s Report (hereafter referred to as “Report”) has been prepared in connection with the formation of said District and the levy and collection of annual assessments related thereto commencing in fiscal year 2024-2025, as required pursuant to Section 54716 of the 1982 Act.
The City Council pro poses to form the District, and levy and collect annual ass essments on the County tax roll to provide ongoing funding for the costs and expenses required to service and maintain drainage improvements and appurtenant facilities that are necessary and essent ial requirements for the development of the properties within the District to cause the protection of those properties and the surrounding ecological environment from flooding. The improvements to be provided by the District and the assessments described herein are made pursuant to the 1982 Act and the substantive and procedural provisions of the California Constitution.
The formation of this District and the assessments described herein will provide a funding source for the continued operation and maintena nce of the drainage improvements that are directly associated with the development of properties within the District and for the special benefit of those properties.
The budgets and assessments described in this Report are based on the planned improvement s and development requirements associated with Tract No. 82126 . The budgets described herein, represent an estimate of the direct expenditures, incidental expenses, and fund balances that will be necessary to ensure proper maintenance, servicing and funding needs to support the drainage improvements that provide special benefit to properties within the District.
The word “parcel,” for the purposes of this Report, refers to an individual property assigned its own Assessor’s Parcel Number (APN) by the Los Angeles County Assessor’s Office. The Los Angeles County Auditor-Controller uses APNs and specific Fund Numbers to identify properties to be assessed on the tax roll for the special benefit assessments.
As part of this District formation, the City shall conduct a property owner protest ballot proceeding for the proposed levy of a new assessment pursuant to the provisions of the California Constitution, Article XIIID Section 4. In conjunction with this ballot proceeding, the City Council will conduct a public hearing to consider public testimonies, comments and written protests regarding the formation of the District and levy of assessments. Upon conclusion of the public hearing, property owner protest ballots received will be opened and tabulated to dete rmine whether majority protest exists (ballots shall be weighted based on the calculated proportional assessment amount for each benefiting parcel), and by resolution the City Council will confirm the results of the ballot tabulation. If majority protest exists, proceedings for the formation of the District and the levy of the proposed assessments shall be abandoned. If tabulation of the ballots indicates that majority protest does not exist for the proposed assessments and the assessment range formula presented and described herein, the City Council may approve the Report (as submitted or amended), order the formation of the District, and approve the levy and collection of assessments. In such case, the assessments for fiscal Engineer’s Report
City of Santa Clarita
Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
year 2024-2025 shall be submitted to the Los Angeles County Auditor-Controller for inclusion on the property tax roll for each parcel.
Each subsequent fiscal year, a Report shall be prepared and presented to the City Council describing any changes to the improvements, the proposed services, the annual budget and assessments for that fiscal year, and the City Council shall hold a noticed public hearing regarding these matters prior to approving and ordering the proposed levy of assessments.
This Report consists of five (5) parts.
Part I
Plans and Specifications: A description of the District boundaries and the proposed improvements associated with the District. The District is being formed with a single benefit zone encompassing all properties within the territory identified as Drainage Benefit Assessment Area No. 2023-1 (Tract No. 82126).
Part II
Method of Apportionment: A discussion of benefits the improvements and services provide to properties within the District and the method of calculating each property’s proportional special benefit and annual assessment. This section also identifies and outlines an Assessment Rang e Formula that provides for an annual adjustment to the maximum assessment rate that establishes limits on future assessments, but also provides for reasonable cost adjustments due to inflation without the added expense of additional property owner protest ballot proceedings.
Part III
District Budget: An estimate of the annual costs to operate, maintain and service drainage improvements related to the properties within the District. This budget includes an estimate of anticipated direct maintenance costs an d incidental expenses including, but not limited to administration expenses and the collection of appropriate fund balances to establish an initial maximum assessment to be approved by the property owners of record. The special benefit maximum assessment p roposed for this District is based on an estimate of the annual maintenance and operational expenses at full build out of the improvements. The proposed assessments for the first fiscal year ( 2024- 2025), and each subsequent year shall be based on the estim ated net annual cost of operating, maintaining and servicing the District improvements for that fiscal year. The proposed maximum assessment (Rate per Equivalent Benefit Unit) identified in the budget of this Report establishes the initial maximum assessme nt rate for the District in fiscal year 2024-2025 and shall be adjusted annually by the Assessment Range Formula described in the method of apportionment.
Part IV
District Diagram: A Diagram showing the exterior boundaries of the District is provided in this Report and includes all parcels that will receive special benefits from the improvements. Parcel identification, the lines and dimensions of each lot, parcel and subdivision of land within the District, are inclusive of all parcels as shown on the Los Angeles County Assessor's Parcel Maps as they existed at the time this report was prepared and includes all subsequent subdivisions, lot line adjustments or parcel changes therein. Reference is hereby made to the Los Angeles County Assessor’s maps for a detailed description of the lines and dimensions of each lot and parcel of land within the District.
Part V
Assessment Roll: A listing of the proposed assessment amount to be presented to the property owners of record during the protest ballot proceedings required pursuant to the provisions of the California Constitution. The proposed assessment amount for each parcel is based on the parcel’s proportional special benefit as outlined in the method of apportionment and the proposed initial maximum assessment rate.

Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
PART I — PLANS AND SPECIFICATIONS
PROPERTIES WITHIN THE DISTRICT
Drainage Benefit Assessment District No. 2023-1, will consist of five (5) previously built residential properties along with Tract No. 82126 slated for three hundred seventy-one (371) residential properties (196 Single Family Residential Units and 175 Townhomes/Condominiums) with associated private streets, storm drain, utilities, and landscaping.
The purpose of the District is to ensure the ongoing maintenance, operation, and servicing of drainage improveme nts installed in connection with development of properties within the District. This District will provide the financial mechanism (annual assessments) by which the ongoing operation and maintenance of these improvements will be funded.
The District structure, proposed improvements, method of apportionment and assessments described in this Report are based on current development and improvement plans including all estimated direct expenditures, incidental expenses, and reserves associated with the maintenance and servicing of the improvements.
The District is located within the boundaries of the City of Santa Clarita, generally situated along Bouquet Canyon Road.
FUNDING AUTHORIZED BY THE 1982 ACT
As generally defined by the Benefit Assessment Act of 1982 and applicable to this District, the City may impose a benefit assessment to finance the maintenance and operation costs of the following services:
1) Drainage; and
2) Flood Control.
In addition to imposing a benefit assessment for the annual maintenance an d operation of the District improvements, the City may also authorize an assessment or utilize existing assessment revenues to finance the installation, construction or replacement of drainage and flood control facilities. While such activities are permitted under the 1982 Act, the budget and assessments for this District only provide for normal maintenance and operation of the improvements. Since most major rehabilitation/construction projects result from unforeseen damages, the extent and cost of such projects are not easily predicted and to accumulate funds as part of the normal annual assessments is not practical. If such funding becomes necessary, the City may present a new or increased assessment to the property owners to support such projects.
IMPROVEMENTS AND SERVICES
The purpose of this District is to fund the activities necessary to maintain and service the corresponding drainage improvements required of properties within the District. The maintenance and operation of these improvements may include but are not limited to all materials, equipment, labor, and incidental expenses deemed necessary to keep these improvements in satisfactory condition , as well as the collection of assessment installments for periodic service activities, repair or rehabilitation of various improvements and facilities (not capital improvements expenditures or replacement of the drainage infrastructure).
Commented [KK1]: Will have Sikand confirm one more time Engineer’s Report

Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
Detailed maps and descriptions of the location and extent of the improvements to be maintained by the District are on file with the Environmental Service s Division and by reference are made part of this Report. These plans and specifications may be amended or modified from time to time to reflect future property development within the District or necessary changes to the planned developments currently approved by the City. The net annual cost to provide and maintain the improvements determined to be of special benefit shall be allocated to each property in proportion to the special benefits received from those various improveme nts. The District improvements and services are generally described as follows.
DRAINAGE MAINTENANCE
The proposed services involve the maintenance and operation of three (3) Continuous Deflection Separation (CDS) systems along with four (4) Filterra units, two (2) infiltration basins, two (2) biofiltration basins and one (1) In let with Diversion Weir as identified in the “Preliminary Cost Estimate provided by Sikand Engineering.”
The project will discharge into storm drainpipes that drain Bouquet Creek, which is lined, and from there discharged to the Santa Clara River. The CDS will treat runoff from portions of the Bouquet Canyon Development where it joins the existing road on the north as well as the easterly side of existing Bouquet Canyon Road and is designed to remove trash, debris and coarse sediment from incoming flows . The Filterra units are designed to capture and immobilizes pollutants. The infiltration basins will have vegetated depression to store runoff and will be located adjacent to Bouquet Creek, adjacent to Bouquet Canyon Road , and northerly of Bouquet Creek on the east side of the project . The biofiltration basins will provide water quality treatment for the Pollutants of Concern and will be located near the intersection of Pam Court and existing Riverglen Drive and at the southeasterly co rner of the project where the realignment of Bouquet Canyon Road begins.

(Bouquet Canyon - Tract No. 82126)
Part II — METHOD OF APPORTIONMENT
The 1982 Act permits the establishment of assessment districts by agencies for the purpose of providing for the maintenance, operation and servicing of drainage and flood control improvements as well as streets, roads , and appurtenant facilities. The 1982 Act further requires that the cost of these improvements be levied according to benefit rather than assessed value:
“The amount of the assessment imposed on any parcel of property shall be related to the benefit to the parcel which will be derived from the provision of the service.” Furthermore:
“The annual aggregate amount of the assessment shall not exceed the estimated annual cost of providing the service, except that the legislative body may, by resolution, determine that the estimated cost of work authorized … is greater than can be conveniently raised from a single annual assessment and order that the estimated cost shall be raised by an assessment levied and collected in installments…. The revenue derived from the assessment shall not be used to pay the cost of any service other than the service for which the assessment was levied.
The method of apportionment described in this Report for allocation of special benefit assessments reflects the composition of parcels within the District and the improvements and services provided, to fairly apportion the costs based on the special benefits to each parcel.
BENEFIT ANALYSIS
The ongoing maintenance and servicing of the District improvements is an integral part of the use and preservation of the properties within the District and as such confer a particular and distinct special benefit to those parcels. The proper maintenance of the improvements and appurtenant facilities allows individual parcels to be developed and used to their fullest extent by ensuring adequate drainage and proper control of excess water during periods of rain, which is essential to preservation and protection of private property. In reviewing the USMP and Environmental Impact Report (EIR) prepared in connection with the development of properties in Bouquet Canyon Tract No. 82126 (which contains all parcels within the District) it was determined that improvements to be maintained are necessary to provide drainage and control of excess water during periods of rain for properties within the District . That analysis indicated that the drainage and flow of excess water during periods of rain from surrounding proper ties will not be addressed by the proposed District improvements and these improvements are only necessary to mitigate water run -off from the properties in the District. Therefore, it has been determined that these drainage improvements and the maintenance and servicing of such improvements is entirely a special benefit to properties in the District and there is no quantifiable general benefit to properties or the public at large.
ASSESSMENT METHODOLOGY
All costs associated with the improvements and services shall be fairly distributed among the parcels based upon the special benefit received by each parcel. Additionally, in compliance with the California Constitution Article XIIID Section 4, each parcel’s assessment may not exceed the reasonable cost of the proportional special benefit conferred to that parcel. The method of apportionment established for this District and described herein, reflects the proportional special benefit each property receives from the improvements and services based on the actual or proposed land use of that parcel as compared to other properties within the District. The benefit formula used to determine the assessment obligation for each parcel is based upon both the type of improvements that benefit that particular parcel as well as the proposed land use of each property as compared to other parcels that benefit from those specific improvements.
Engineer’s Report
City of Santa Clarita
Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
Upon review of the improvements and the proposed development of properties within the District it has been determined that all properties receive similar special benefits from each of the improvements and services to be funded by annual assessments and a single zone of benefit is appropriate for the allocation of the assessments and proportional special benefit.
Equivalent Benefit Units
To assess benefits equitably it is necessary to relate each property’s proportional special benefits to the special benefits of other properties within the District. The method of apportionment established for most districts formed under the 1982 Benefit Act utilizes a weighted method of apportionment known as an Equivalent Benefit Unit (EBU) methodology that uses a weighted EBU based on an assessment formula that equates the property’s specific development characteristics such as land use and size to that of other properties in the District.
Because this District will ultimately be for residential use, the single-family residential unit or lot is assigned one (1.0) EBU and other property types (land uses) are proportionately weighted (weighted EBU) based on a benefit formula that equates each property’s specific characteristics and special benefits to t hat of the single -family residential unit.
Based on the planned development of properties in Tract No. 82126, the following land use classifications and proportional EBUs are outlined as follows.
Single-Family Residential Property —defined as a fully subdivided residential home site with or without a structure.
For purposes of establishing the proportional special benefits and EBUs for other land uses in this District, the single- family residential land use is designated as the basic unit of assessment and shall be assigned 1.000 EBU per parcel.
Vacant Property —defined as property that has been identified as undeveloped but has reasonable development potential ( few or no development restrictions). When considering the special benefits from the improvements it becomes evident that the proportional special benefits associated with vacant property is less than that of developed properties because the full improvement infrastructure associated with the property has likel y not been installed, but they do benefit from the overall drainage improvements such as the drainage basin. Therefore, the EBUs applied to these properties shall be based on 0.500 EBU per planned residential unit for the property or 1.00 EBU per acre if the number of planned residential units is unknown.
Exempt Property (Parcel) — identifies parcels that for various reasons, it has been determined that the parcel does not and will not receive special benefits from the improvements. This land use classification may include but is not limited to:
➢ Lots or parcels identified as public streets and other roadways (typically not assigned an APN by the County); ➢ Dedicated public easements including open space areas, utility rights -of-way, greenbelts, parkways, or other publicly-owned or utility -owned lan d that serves the community or general public and are not considered or classified as developed public properties; and
➢ Parcels of land that are privately owned but cannot be developed independently from an adjacent property or is part of a shared interest with other properties, such as common areas, sliver parcels, bifurcated lots or properties with very restrictive development potential or use.
Because these properties either provide a public service that is comparable to landscaping or street lighting improvements, or they are dependent on another property or development, these types of parcels have no direct need for such improvements and are considered to receive no special benefits Therefore these parcels shall be exempt from assessment and are assigned 0.0000 EBU. However, these properties shall be reviewed annually by the assessment engineer to confirm the parcel’s use and/or development status has not changed.
Special Case Property — In many districts where multiple land use classifications are involved or the properties being developed are being constructed in phases , there may be one or more properties that the standard land use classifications do not accurately identify the use and special benefits received from the improvements or there may be something about that particular parcel that should be noted for review in subsequent fiscal years.
Engineer’s Report
City of Santa Clarita
Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
The EBUs assigned to Special Case Properties will vary depending on the circumstances and reasons for treating each particular property as a Special Case. The EBU(s) assigned to each such parcel may be based on adjusted acreage, units, planned subdivided lots, or a combination of those factors. The City and/or the assessment engineer tasked with the administration of the District shall annually review each parcel designated as a Special Case Property and based on that review shall make appropriate adjustments to that property’s land use and EBU assignment as warranted.
Proposed Land Use Tract 82126
Property Type Equivalent Benefit Units
Residential 1.00 per Lot/Unit
Vacant Property 0.50 per Planned Lot/Unit
Vacant Property (Unknown Units) 1.00 per Acre
Exempt Parcel 0.00 per Lot/Parcel
Assessment Calculations
The total number of Equivalent Benefit Units (EBUs) is the sum of all individual EBUs applied to parcels that receive special benefit from the improvements. An assessment amount per EBU (Assessment Rate) for the improvements is established by taking the to tal cost of the improvements and dividing that amount by the total number of EBUs of all parcels benefiting from the improvements. This rate is then applied back to each parcel’s individual EBU to determine the parcel’s proportionate benefit and assessment obligation for the improvements.
Total Balance to Levy / Total EBU = Levy per EBU
Levy per EBU x Parcel EBU = Parcel Levy Amount
ASSESSMENT RANGE FORMULA
Any new or increased assessment requires certain noticing and meeting requirements by law. Prior to the passage of Proposition 218 (California Constitution Articles XIII C and XIII D), legislative changes in the Brown Act defined a “new or increased assessment ” to exclude certain conditions. These conditions included “any assessment that does not exceed an assessment formula or range of assessments previously adopted by the agency or approved by the voters in the area where the assessment is imposed.” This definition and conditions were later confirmed through Senate Bill 919 (Proposition 218 implementing legislation).
The purpose of establishing an Assessment Range Formula is to provide for reasonable increases and inflationary adjustment to annual assessments without requiring costly noticing and mailing procedures . Commencing with fiscal year 2024-2025, the amount of the maximum assessment will increase to adjust for increases in labor and material costs. This increase will be based upon the annual change in the Consumer Price Index, All Urban Consumers, for the Los Angeles-Long Beach-Anaheim Area, as determined by the United States Department of Labor, or its successor, without conducting another mailed ballot election.
Engineer’s Report
City of Santa Clarita
Drainage Benefit Assessment Area No. 2023-1
(Bouquet Canyon - Tract No. 82126)
The Maximum Assessment is adjusted annually and is calculated independent of the annual budget and proposed annual assessment. Any proposed annual assessment (rate per EBU less than or equal to this Maximum Assessment) is not considered an increased assessment, even if the proposed assessment is greater than the assessment applied in the prior fiscal year.
Although the Maximum Assessment will increase each year, the actual assessment may remain unchanged. The Maximum Assessment adjustment is designed to es tablish a reasonable limit on assessments. The Maximum Assessment calculated each year does not require or facilitate an increase to the annual assessment and neither does it restrict assessments to the adjusted maximum amount. If the budget and assessment for the fiscal year do not require an increase, or the increase is less than the adjusted Maximum Assessment, then the required budget and assessment may be applied without additional property owner balloting. If the budget and assessments calculated requ ires an increase greater than the adjusted Maximum Assessment, then the assessment is considered an increased assessment and would be subject to balloting.

Part III — DISTRICT BUDGETS
The Benefit Assessment Act of 1982 (hereinafter “the Act”) provides that the estimated costs of the improvements shall include the total cost of the improvements, including incidentals, which may include reserves to operate the District until funds are transferred to the City.
The Act also provides that the amount of any surp lus, deficit or contribution be included in the estimated cost of improvements. The net amount to be assessed on the lots or parcels within each district is the total cost of maintenance and servicing with adjustments either positive or negative for reserves, surpluses, deficits, and/or contributions.
The budget on the following page outlines the estimated annual costs to be collected and deemed necessary for the operation, maintenance , and servicing of the improvements for the District. The maximum assessment (Rate per Equivalent Benefit Unit) identified in the budget establishes the initial maximum assessment for the District in fiscal year 2023/2024. This assessment rate shall be adjusted annually by the Assessment Range Formula described in the method of apportionment and collectively this assessment rate and inflationary adjustment will be presented to the property owners of record for approval as part of the balloting process for new or increased assessments in accordance with the provisions of the California Constitution, Article XIII D.

(Bouquet Canyon - Tract No. 82126)
Part V — ASSESSMENT ROLL
Parcel identification for each lot or parcel within the District is outlined in the preceding Assessment Diagram and is based on available parcel maps and property data from the Los Angeles County Assessor’s Office at the time this Engineer’s Report was prepared. A listing of the lots and parcels to be assessed within this District as of fiscal year 2023/204, along with the assessment amount for each such lot or parcel is provided below.
If any parcel submitted for collection is identified by the County Auditor -Controller to be an invalid parcel number for the fiscal year, a corrected parcel number and/or new parcel numbers will be identified and resubmitted to the County Auditor-Controller. The assessment amount to be levied and collected for the resubmitted parcel or parcels shall be based on the method of apportionment and assessment rates describ ed in this Report as approved by the City Council. Therefore, if a single parcel is subdivided to multiple parcels, the assessment amount applied to each of the new parcels shall be recalculated and applied according to the approved method of apportionment and assessment rate rather than a proportionate share of the original assessment amount.
The following is a list of the lots and parcels of land (parcels) within the District and the corresponding maximum assessments being set for Fiscal Year 2023/2024 as determined by the assessment rate and method of apportionment described herein:
