B. The specific purpose of the Clean Water and Storm Protection fee established pursuant to this chapter is to derive fee revenue, which shall only be used for the acquisition, construction, reconstruction, maintenance, and operation of the storm drainage system of the City or related green infrastructure or other activities required by the City’s NPDES permits, to repay principal and interest on any bonds which may hereafter be issued for said purposes, to repay loans or advances which may hereafter be made for said purposes, and for any other purpose set forth in Section 3.38.160.
C. The Clean Water and Storm Protection fee is imposed pursuant to Articles XIII C and D of the California Constitution, Government Code Sections 38900 - 38901 and 53755 - 53756, and Health and Safety Code Section 5471 - 5473.11.
D. Proceeds from the Clean Water and Storm Protection fee will be deposited in the “environmental management/clean creeks fund” created by Section 3.36.170 of Chapter 3.36 of the Municipal Code (Storm Drainage Service Charge) as the “storm drainage service charge fund” and subsequently renamed, and may be comingled with the revenues of the City’s storm drainage service charge because they are authorized to be used for the same purposes.

3.38.030 Determination and imposition of fee for fiscal year 2019-20.¶
For purposes specified in Section 3.38.010, the Clean Water and Storm Protection fees established pursuant to this chapter are hereby prescribed and imposed, and shall be paid to and collected by the City, for services and facilities furnished by the City in connection with its storm drainage system to or for each parcel which is benefited directly or indirectly by said storm drainage system or any part thereof, or from which any storm water is conveyed or discharged directly or indirectly into the storm drainage system. Said fee is imposed annually and will be assessed and collected as follows:
A. Single-Family Residential Class
| Category | Parcel Size (acres) | Annual Fee per Parcel |
|---|---|---|
| Small | Under 0.13 | $36.58 |
| Medium | 0.13 to 0.22 | $44.42 |
| Large | 0.23 to 0.40 | $55.58 |
| Extra Large | Over 0.40 | $106.42 |
| Condominium 1 | Na | $36.58 |
| Condominium 2+ | Na | $11.99 |
B. Non-Single-Family Residential Class
| Category 1 | Annual Fee per 0.10 Acre of Parcel Size 2 |
|---|---|
| Multi-Family | $30.88 |
| Commercial/ |
$40.38 |
| Office | $30.88 |
| Church/ |
$26.13 |
| School with play field | $19.00 |
| Park | $7.13 |
| Vacant (developed) | $2.38 |
Rate Structure Notes:
The Rate Category for any Non-Single-Family parcel shall be assigned by the description of the land use of the parcel. For Non-Single-Family land uses that do not fit the descriptions in Table 5 of the Fee Report (for example, mixed use parcels), the rate with the nearest percent impervious area shown in Table 5 of the Fee Report shall be assigned to a parcel.
Non-Single-family fees are calculated in 0.1-acre increments. For example, an office parcel is charged at $30.88 for each tenth of an acre or portion thereof.
C. Non-single-family parcels and condominium parcels that comply with the version of Provision C.3 (New Development and Redevelopment Requirements) of the City’s NPDES permit that is applicable at the time of building permit issuance shall have their fees reduced by 25% in recognition of the reduced impact on the City’s storm drainage system inherent in C.3 compliance, as documented in the Fee Report (Low Impact Development Rate Adjustment). Other single-family residential parcels do not qualify for this rate reduction. C.3 compliance will be determined on a case-by-case basis by the Director of Public Works, who may also establish procedures to verify and validate such compliance on a periodic basis.
D. For non-single-family residential parcels that have both improvements and significant open space areas (described in the Fee Report as “hybrid parcels”), the chargeable acreage shall be adjusted downward in recognition that the open space areas do not increase the need for the fee.
E. Open space and agricultural parcels are not subject to the Clean Water and Storm Protection fees.
(Ord. 19-2183, 2019)
3.38.040 Annual review of fee.¶
Commencing with Fiscal Year 2020-21, the City Council shall, by resolution, annually determine the Clean Water and Storm Protection Fee in accordance with the following:
A. In no event shall the rate for any category of property be increased beyond the rate approved by a majority vote of property owners subject to the Clean Water and Storm Protection fee. Commencing in Fiscal Year 2020-21, the amount of the Clean Water and Storm Protection Fee may be increased by an amount equal to the change in the Consumer Price Index for all Urban Consumers for the area including Santa Clara County (the “CPI”), including all items as published by the U.S. Bureau of Labor Statistics as of December of each succeeding year, not to exceed a maximum increase of three percent (3%) in any single year. Adjustments will only occur if actual additional costs are incurred.
B. The Clean Water and Storm Protection fee shall not be deemed to be increased in the event the actual fee upon a parcel in any given year is higher due to a change in use of the subject parcel or an increase in the amount of the impervious area of the subject parcel.
C. In any year in which the City Council does not change the Clean Water and Storm Protection fee rate, pursuant to the voter-approved CPI allowable annual increase, the previously adopted fee shall continue in full force and effect for the next fiscal year.
D. The City Council shall not be required to enact a CPI increase each year. 3.38.040.A.

C. The City Clerk shall cause notice of the filing of said report and of a time and place of hearing thereon to be published, prior to the date for hearing, in a newspaper of general circulation printed and published within the City. The publication of said notice shall be once a week for two consecutive weeks.

The period of notice commences upon the first day publication and terminates at the end of the fourteenth day.
D. At the time stated in the above-mentioned notice, the City Council shall hear and consider all objections or protests, if any, to the report referred to in said notice, and may continue the hearing from time to time. If the Council finds that protest is made by owners of a majority of separate parcels of property described in the report, then the report shall not be adopted, and fees shall be collected separately from the tax roll and shall not constitute a lien against any parcel or parcels.
E. Upon the conclusion of the hearing, the City Council may adopt, revise, change, reduce, or modify any fee or overrule any or all objections and shall make its determination upon each fee as described in said report, which determination shall be final.

The Finance Director shall thereupon cause said fees to be placed on the property tax roll and collected by the County for the City, as hereinafter provided. The County’s tax collector shall enter the amounts of the fees against the respective parcels as they appear on the current assessment roll. If the property is not described on the roll, the County’s tax collector may enter the description thereon, together with the amounts of the fees as shown in the report.
G. The amount of the fees shall constitute a lien against the parcel against which the fee has been imposed as of noon on the first Monday in March immediately preceding the date of the levy.
H. The tax collector shall include the amount of the fees on bills for taxes levied against the respective parcels. Thereafter the amount of the fees shall be collected at the same time and in the same manner and by the same persons as, together with and not separately from, the general taxes for the City, and shall be delinquent at the same time and thereafter be subject to the same delinquency penalties.
I. All laws applicable to the levy, collection and enforcement of general taxes of the City including, but not limited to, those pertaining to matters of delinquency, collection, cancellation, refund and redemption, are applicable to such fees.
J. The tax collector may, at the tax collector’s discretion, issue separate bills for such fees and separate receipts for collection on account of such fees.
K. If any parcels receiving benefit from the storm drainage system are omitted from the abovementioned report or said tax roll, either because the fee therefor shall not have yet been ascertained by the City as of the date of said report, or for any other reason, the Clean Water and Storm Protection fee for such parcels shall be collected in the manner provided elsewhere in this chapter. If the fee for any parcels, as shown on said report for the forthcoming fiscal year, should be less than what should be the fee therefor under the provisions of this chapter, the balance of such fee shall be collected in the manner provided elsewhere in this chapter. If, however, the fee for any parcels shown in the report and collected on the tax roll should exceed the correct fee for such parcels for the fiscal year, the Finance Director shall refund the excess amount so collected.
