ENGINEER’S REPORT
for
HAYWARD GEOLOGIC HAZARD ABATEMENT DISTRICT
PARCEL GROUP 3 DEVELOPMENT ANNEXATION
HAYWARD, ALAMEDA COUNTY, CALIFORNIA
for the
ESTABLISHMENT OF AN ASSESSMENT LIMIT
I. INTRODUCTION
The Hayward City Council formed the Hayward Geologic Hazard Abatement District (“GHAD” or “District”) on March 1, 2016 (Resolution No. 16-030), under the authority of the California Public Resources Code, Division 17, Section 26500 et seq. The GHAD Board of Directors approved the annexation of the Parcel Group 3 Development (“GHAD Annexation Area”) into the GHAD on August XX, 2025, with the approval of Resolution No. XX-XX. The members of the Hayward City Council act as the Board of Directors of the GHAD.
II. BACKGROUND
The Hayward GHAD Board of Directors approved the Plan of Control for the Parcel Group 3 Development Annexation (“Plan of Control”) with the approval of Resolution No. XX-XX on August XX, 202 5. The Plan of Control describes the GHAD’s responsibilities to permanently monitor and maintain GHAD improvements within the GHAD Annexation Area. This Engineer’s Report describes the establishment of an assessment level to fund GHAD activities necessary or incidental to geologic hazard mitigation, abatement, and control.
III. GEOLOGIC HAZARD ABATEMENT DISTRICT BOUNDARIES
The boundaries for the GHAD Annexation Area are shown in the legal description and plat attached hereto as Exhibit A.
IV. SERVICE LEVELS

3. Engagement of technical professionals to perform the monitoring duties as described in the Plan of Control.
4. Performance of GHAD maintenance activities in accordance with the Plan of Control. These maintenance activities include:
• Surface Drainage Improvements : The GHAD maintain s surface drainage improvements, including drainage ditches, to manage stormwater runoff and prevent flooding or erosion.
• Functional Aspects of Water Quality Flow Control Basins and Stormwater Facilities: The GHAD handles functional maintenance, repair, and replacement of water quality flow control basins and stormwater facilities, including retention detention ponds, to manage runoff and minimize flood risks.
• Storm Drainage System: The GHAD maintain s the storm drainage system to support proper function and reduce geologic hazard risks.
• Retaining Walls: The GHAD maintain s retaining walls and drain outlets to preserve structural integrity.
• Geotechnical Monitoring Instruments (if any): The GHAD monitor s and maintain s geotechnical instruments used to track soil movement and other geotechnical factors. • Keyway Subdrains and Outlets: The GHAD maintains keyway subdrains and outlets to prevent blockages and sustain proper slope drainage.
• Geologic Hazard Abatement: The GHAD monitor s and mitigate s geologic hazards, including slope stability and erosion control.
5. Preparation of annual GHAD budgets for approval by the GHAD Board of Directors.
V. DESCRIPTION OF THE IMPROVEMENTS MAINTAINED BY
THE GHAD
The GHAD -maintained improvements are described in the Plan of Control. In general, these improvements include drainage systems, including concrete-lined ditches in developed areas and open space; open-space storm drain inlets and outlets; subdrains and outlets; and selected retaining walls.
VI. ASSESSMENT METHOD
The improvements and GHAD responsibilities described in Section V are distributed within the GHAD Annexation Area. The improvements described in this document will confer the following special benefits to the assessed parcels.
1. Protection from slope instability.
2. Protection from erosion due to uncontrolled surface water.
3. Protection of water quality.
Hayward Geologic Hazard Abatement District Parcel Group 3 Development Annexation 15577.000.001 Engineer’s Report
Page | 5 November 11, 2025
The GHAD assessment is distributed among all residential and commercial/educational property owners within the GHAD Annexation Area. The improvements and responsibilities listed in Section IV provide specific benefits to the properties within the GHAD Annexation Area and the improvements are constructed for the benefit of those assessed and not the general public.
The GHAD Annexation Area consists of 214,693 planned square feet of habitable structures which include a childhood center, elementary school, and two residential complexes which include 176 units . The total area of habitable space within the GHAD Annexation Area was considered in light of the annual GHAD Annexation Area budget in developing the annual assessment limit.
The Engineer hereby finds that the planned structures within the GHAD Annexation Area receive approximately equal special benefit from the work and improvements within the GHAD based on the percentage of habitable square footage within each of the structures . As a result, the GHAD assessment for the GHAD Annexation Area is distributed among all owners of parcels as follows:
PRODUCT TYPE SQUARE FOOTAGE PERCENTAGE OF
TOTAL ASSESSMENT
Childhood Center 10,994 5.1%
Elementary School 35,460 16.5%
Residential – Building 1 84,829 39.5%
Residential – Building 2 83,460 38.9%
TOTAL 214,693 100%
A financial analysis was performed to provide a framework for an operating budget for the on-going abatement, mitigation, prevention and control of geologic hazards within the GHAD Annexation Area. In preparation of the budget, several factors were considered including:
1. Site geology
2. Remedial grading
3. Proximity of geologic hazards to proposed structures
4. Improvements and structures
5. Site access considerations
6. Elements requiring routine maintenance, including:
• Surface drainage facilities
• Graded slopes
• Retaining walls
VII. ASSESSMENT – BUDGET
The purpose of this Engineer’s Report is to establish the assessment level and the apportionment of the assessment within the GHAD Annexation Area as required under Proposition 218. The annual budget in each subsequent fiscal year will apprise the GHAD Board of Directors of the estimated budget for the upcoming year.
Based on the estimated expenses for on -going operations, and allowing for larger (approximately $200,000) geologic events at 20-year intervals and accumulation of a target reserve of $ 510,000 by FY 2075/76 in FY 2025/26 dollars, a budget was prepared for the Hayward Geologic Hazard Abatement District Parcel Group 3 Development Annexation 15577.000.001 Engineer’s Report
Page | 6 November 11, 2025
purpose of estimating initial assessment levels (Exhibit B). For the purposes of establishing an assessment limit, it was anticipated that the target reserve w ould accumulate over a 50 -year period; however, the target reserve may accumulate at a slower or more rapid rate than estimated depending on the GHAD’s actual expenses and revenues.
The Engineer recommends an annual assessment limit for the GHAD Annexation Area of $0.25472 per square foot of habitable space (Fiscal Year 2025/26 dollars). The proposed initial assessment level will be automatically adjusted annually on December 30 to reflect the percentage change in the San Francisco -Oakland-San Jose Consumers Price Index for All Urban Consumers. The assessments are to be levied in conjunction with the issuance of a certificate of occupancy for each of the structures.
While the assumptions and estimated expenses listed in Exhibit B were used to determine the assessment levels for the GHAD Annexation Area, they do not represent the actual budget for any one year of the GHAD’s operation, since assessment of the individual structures will be based on the issuance of building permits, which may occur over a number of years. In addition, the Engineer anticipates that the projected expense amounts will be reached over time and that these amounts will be inflation-adjusted in the year that the expenses occur.
Pursuant to the schedule set forth in Section 6.4 of the Plan of Control for the Parcel Group 3 Development, the GHAD reserve at the time of transfer must have a minimum of $114,910. In addition, all four planned structures shall be subject to the levy of the GHAD assessment. The minimum reserve amount represents the estimated total assessments that will be collected from within the Parcel Group 3 Development during the period the Owner is responsible for all GHAD activities. The reserve amount requirement may be satisfied by including remaining cash and receivables from the Alameda County Tax Collector during the period that the Owner of the Parcel Group 3 Development is responsible for performing the GHAD activities. Additional funds may be required of the developer in order to satisfy the above-stated minimum reserve requirement and shall be provided to the Hayward GHAD prior to its acceptance of the monitoring and maintenance responsibilities within the Parcel Group 3 Development.
VIII. OWNER RESPONSIBILITIES
La Vista Hayward, L.P. , (“Owner”) is responsible for managing and maintaining the GHAD Annexation Area until the GHAD accepts responsibility for the GHAD Improvements as set forth in the Plan of Control . In addition, the Owner is responsible for funding any necessary GHAD functions or business undertaken for the GHAD Annexation Area that the GHAD Officers or Board of Directors determine are necessary before the GHAD accepts the GHAD Improvements. If the Owner fails to fund all or a portion of these costs, the costs shall be covered by the funds generated by and for the GHAD Annexation Area (i.e., t hrough the assessment) and the Owner shall be required to reimburse the GHAD for such costs before the GHAD can accept monitoring and maintenance responsibilities for the GHAD Improvements.
The GHAD may utilize funds generated by or for the GHAD Annexation Area to conduct any necessary GHAD functions or business for the GHAD Annexation Area required before the GHAD accepts the GHAD improvements. Such functions and business can include periodic reporting to the GHAD Board of Directors and work performed by GHAD Officers to verify the GHAD is implemented in accordance with the Plan of Control and GHAD Law.
