This engagement encompasses the preparation and filing of the Engineer's Reports with the City Clerk, as well as the submission of the annual levy to the Riverside County Auditor-Controller for the purposes of assessment collection.

The funds generated through these assessments are dedicated to the installation, construction, and ongoing maintenance of the improvements within each district, ensuring the continued upkeep of the City’s landscape and recreational facilities.

Annual Assessment Process

The City Council is further requested to authorize Webb Municipal Finance, LLC, to prepare and file the required Engineer’s Reports concerning the levy and collection of assessments for the five districts in accordance with Chapter 3, Section 22622 of the Act.

RE: Landscape Maintenance Districts FY 26-27 Annual Administration Services Dear Ms. Hamilton:

Webb Municipal Finance, LLC (WMF) is grateful to have the opportunity to continue to work with the City of Norco (the “City”) providing annual administration of Landscape Maintenance District Nos. 1, 2, 3, 4, and 5 (“LMDs”).

We are confident that our project team has the technical expertise, resources, knowledge, relationships and most importantly, the commitment to complete your administration projects on time and within budget. We will tailor solutions to meet your needs.

Our Scope of Services for the LMDs’ annual administration is as shown below:

Kickoff Meeting: The purpose of this meeting is to coordinate with the City to gain an understanding of the specific goals, components and criteria to meet the City’s needs. To that end, WMF will meet with the City staff to confirm the schedule of events, procedural considerations and discuss the City’s preferred method of communication.

Budget Review and Preparation: WMF will review and prepare a budget for each LMD based on the cost estimates for maintenance of all improvements, landscaping, capital improvements and incidental costs, as well as operating and capital improvement reserves. For the LMDs where costs exceed the maximum allowable assessments, WMF will factor into the budget the necessary cuts to bring the expenses in line with the assessments.

Annual District Engineering and Engineer’s Report Preparation: Prior to the annual public hearing confirming the LMDs assessments, WMF will file the Engineer’s Reports with the City Clerk. The Engineer’s Reports will include the fiscal year’s budget information, the listing of improvements to be maintained by the collection of the special assessments, the benefit spread methodology, a copy of plans and specifications, estimates of the costs, assessment diagrams, and complete listings of parcels to be assessed and their total assessments. The reports will be prepared in accordance with California Code. WMF’s Engineer’s Reports will include a statement of engineer signed by a Professional Engineer verifying the accuracy of the report. The original copy of the Engineer’s Report will be provided to the City.

Preparation of Resolutions: WMF, in coordination with the City Attorney and City Staff, will assist in the preparation of all resolutions and staff reports needed for the annual administration process.

Meeting Attendance: For each item requiring City Council action, WMF will attend all City Council Meetings pertaining to the LMDs. WMF will provide a PowerPoint presentation for City Staff to present at the Council Meetings and be available to answer any questions posed by City Staff, City Council Members, or the public. As requested by City Staff, WMF will be available to attend all Property Owner Meetings regarding the LMDs’ annual assessments and answer questions.

Page 224 of 237 ends

Annual Special Assessment Submittal: WMF will calculate and submit the annual levy for the LMDsto the Riverside County Auditor-Controller. Included with the annual levy submittal is the preparation of direct invoices (handbills) to all public agencies whose properties are determined to receive a direct benefit from the public improvements.

WMF will submit the annual levies for the LMDs in the media format, and configuration acceptable for direct submission to the Riverside County Auditor-Controller’s Office prior to the statutory deadline and shall perform adjustments and corrections to the levies on the property tax rolls as necessary.

District Mapping: WMF will obtain the latest assessor’s parcel maps and secured tax roll information from the Riverside County Assessor’s Office for the parcels within the LMDsto identify parcel changes each year. Each year, WMF will provide updated GIS maps and audit maps for the City’s use.

Annual Special Assessment Calculation: As requested by the City, WMF will audit the assessment calculations which include (but are not limited to) the review of EDU computations, parcel acreage, development status, and the taxability status of each parcel.

Property Owner Letters: WMF will assist City Staff with the preparation of property owner letters for applicable LMDs. WMF will generate a mailing list for each applicable district to include current property owner names and mailing addresses using the latest assessor’s parcel maps and Riverside County Assessor’s data as well as our inhouse GIS platform.

Property Owner Services: WMF will serve as the initial and primary contact to City Staff, property owners, title companies, and other interested parties for inquiries regarding the LMDs administration and annual special assessment installments. A toll-free telephone number, of WMF designation, will appear on the regular property tax bill next to each LMD’s line item to facilitate contact with the public.

Roll Changes and Adjusted Property Tax Bills: If any changes to the secured tax roll necessitate corrections/revisions after the deadline are determined necessary, WMF will research, recalculate and, with City approval, rectify the issue. We notify the City of the assessor’s parcel numbers that were rejected by the County and therefore will not be assessed.

RECOMMENDATION:

Adopt Resolution No. 2026-18 denying Accessory Building Use Permit 2025-04 (Ursu).

SUMMARY:

Resolution No. 2026-18 upholds City Council’s March 4, 2026 approval to appeal Planning Commission’s January 14, 2026 approval and hereby denies Accessory Building Use Permit No. 2025-04.

The Planning Commission considered Accessory Building Use Permit No. 2025-04 on January 14, 2026, for the construction of a 1,000-square-foot large vehicle garage with an additional 392-square-foot shop area, and approved the request.

On January 21, 2026, the City Council appealed the Planning Commission’s determination, citing concerns regarding the justification of the findings required to approve the permit.

On March 4, 2026, the City Council reviewed the project information associated with Accessory Building Use Permit No. 2025-04 and considered all written and oral evidence in the record, including the Planning Commission’s action date January 21, 2026.

Page 2 ends

March 18, 2026
FINDINGS:

A. The requested accessory building use permit is not consistent with the General Plan and zoning requirements of the zone in which the property is located, including the protection of adequate open animal areas on lots where the keeping of large animals is permitted. Further, the property is being used as a business, and not in a manner that is compatible with the general plan and zoning of the zone in which the property is located.

B. The requested accessory building use permit will have an adverse effect on the public convenience or general welfare of persons residing or working in the neighborhood and will adversely affect adjoining land uses, including runoff and drainage impacts and architectural compatibility.

NOW, THEREFORE, the City Council of the City of Norco, hereby resolves as follows:

SECTION 1: The City Council of the City of Norco, California, in session assembled on March 4, 2026, overturned the Planning Commission’s determination approving the aforesaid application for an Accessory Building Use Permit and denies said application.

SECTION 2: EFFECTIVE DATE. This resolution shall become effective upon approval by the City Council of the City of Norco.

SECTION 3: NOTICE IS HEREBY GIVEN that this decision is final. The time within which judicial review must be sought is governed by California Code of Civil Procedure section1094.6.

SECTION 4: This notice triggers the running of the 90-day SOL and should be provided on any "final" administrative hearing decision (i.e., a due process hearing where evidence is taken and decision rendered). A decision is "final" when there are no additional options for appeal at the City level.
