The :UR combination district classification is intended to identify those properties inside the sphere of influence of a city as adopted by LAFCOM and a city-adopted urban limit, such as the city of Napa's RUL, whose continued or future urbanization, subject to Section 18.100.030, is contingent upon annexation to the city, as indicated in Napa County general plan policies.

(Ord. 1082 § 3, 1995: Ord. 883 § 1 (part), 1988: Ord. 762 § 1 (part), 1984: prior code § 12398)

B.

Residential care facilities that require the issuance of a use permit prior to commencing operations and all child day care centers shall be permitted upon the granting of a use permit if the principal zoning district with which the :UR zoning district is combined authorizes the establishment of a child day care center or residential care facility, providing a use permit is first secured;

C.

Except as otherwise provided in subsection (A) or (B) of this section, or in Section 18.100.030, additional development shall not be permitted. In all such cases, annexation to an incorporated city shall be required.

18.100.030 - Nonresidential development—Conditions and standards.

A.

Notwithstanding subsection (C) of Section 18.100.020, nonresidential development in the county shall be permitted even though the parcel is included within the :UR zoning district in the following circumstances:

1.

In the case of development which requires the issuance of a use permit, if the approving officer or body, in addition to making the findings required by Section 18.124.070, finds that:

a.

The proposed development is consistent with the general plan and zoning policies of the city that would be applicable were the same development proposed to be located within the city; and

b.

A reasonable annexation request has been made and denied within one year of the use permit application being filed; and

c.

No reasonable use of the property exists should the uses that require the issuance of a use permit in the primary zone continue to be prohibited.

2.

(Reserved.)

3.

In the case of telecommunication facilities, if the commission has made all the findings required under Section 18.124.070 and subsection (A)(1)(a) and (b) of Section 18.100.030 and has issued a use permit for the proposed facility.

B.

For purposes of subsection (A) of this section, a reasonable annexation request shall be deemed to have been made if a complete application to annex the property has been filed with LAFCO or the city and rejected by either entity within one year prior to the date of the application. However, in such a case the development standards imposed as a condition of the permit shall be substantially the same as those required by the city for similar types of development.

C.

No development application shall be deemed complete and accepted for filing by the county until the applicant has provided evidence to the county that an informational copy of the same application has been filed with the city and the city has determined that were the application for a similar development in the city, the application would be considered complete.

D.

If, within sixty days of an application for a use permit being deemed complete by the county and accepted for filing, the city requests that conditions be attached to the issuance of the use permit, the county will ensure that conditions substantially similar to those recommended by the city are imposed unless the county standards are more restrictive than the conditions recommended by the city.

The purpose and intent of these regulations is to protect the public health, safety, and community welfare and to otherwise protect the scenic quality of the county both for visitors to the county as well as for its residents by ensuring that future improvements are compatible with existing land forms, particularly county ridgelines and that views of the county's many unique geologic features and the existing landscape fabric of the county's hillside areas are protected and preserved. These regulations are consistent with the goals and policies of the Napa County general plan, particularly as specified in the land use, open space and conservation, circulation and the scenic highways elements. Furthermore, it is intended that these regulations accomplish the following:

A.

Provide hillside development standards to minimize the impact of man-made structures and grading on views of existing landforms, unique geologic features, existing landscape features and open space as seen from designated public roads within the county;

B.

Protect and preserve views of major and minor ridgelines from designated public roads;

C.

Create a development review process that maximizes administrative, staff level approval of projects which meet administrative standards, while also providing a vehicle for review by the zoning administrator or planning commission of those projects that do not meet the administrative standards;

D.

Minimize cut and fill, earthmoving, grading operations and other such man-made effects on the natural terrain to ensure that finished slopes are compatible with existing land character; and

E.

Promote architecture and designs that are compatible with hillside terrain and minimize visual impacts.

Editor's note— Ord. No. 1334, § 3, adopted January 19, 2010, repealed former Ch. 18.107, in its entirety, which pertained to residential density bonus and incentives. Section 4 of said ordinance enacted provisions designated as a new Ch. 18.107 to read as herein set out. See also the Code Comparative Table and Disposition Table.

18.107.010 - Purpose.

This chapter is intended to produce affordable housing, to provide incentives for the production of affordable housing, and to achieve the following additional goals:

A.

2008 General Plan Update and 2009 Housing Element Update: To implement the goals, objectives, policies, and programs of the county's 2008 General Plan Update and 2009 Housing Element Update related to affordable housing and the affordable housing fund established pursuant to Section 18.107.020.

B.

Development Impacts: To mitigate the impacts of market rate residential development and nonresidential development on the need for affordable housing in Napa County through the imposition of affordable housing requirements as included in this ordinance.

C.

Compliance with State Law: To comply with the provisions of Chapter 4.3 (commencing with Section 65915) of Division 1 of Title 7 of the California Government Code, which mandate the adoption of a county ordinance specifying how compliance with that chapter will be implemented.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.020 - Housing fund—Established.

A.

There is established in Napa County an affordable housing fund (the "housing fund") for the purpose of receiving and disbursing certain monies to address the housing needs of extremely low, very low, low, and moderate income households. Separate accounts within such housing fund may be created from time to time to avoid commingling if required by law or as deemed appropriate to further the purposes of the housing fund.

B.

The board of supervisors may, at its sole discretion, establish by resolution an affordable housing fund board which shall be advisory to the board and to the housing director. The specific functions of the housing board shall be as prescribed by the board of supervisors.

C.

All housing fees collected pursuant to this Chapter 18.107 shall be deposited into the housing fund.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.030 - Housing fund—Administration.

A.

The housing fund shall be administered by the housing director, who shall have the authority to implement the purposes of the housing fund consistent with this chapter, and to prescribe procedures for said purposes, subject to approval by the board.

B.

The housing director shall develop criteria for use of housing fund monies, which shall be subject to board approval. The criteria shall ensure that housing fund monies are used to assist the county in meeting its affordable housing goals, to implement the policies, objectives, and programs set forth in the housing element of the Napa County general plan, as they may be modified from time to time, and to mitigate the impact of new nonresidential development and residential projects on the need for affordable housing in the county.

C.

Concurrently with the development of the county budget, the housing director shall annually present a report to the board that includes a description of monies deposited into the housing fund and their source, the activities undertaken with the housing fund during the reporting period, the relation of housing fund expenditures to housing element policies, objectives, and programs, and to criteria adopted pursuant to subsection (B) above, and recommendations for future expenditures of monies from the housing fund to implement the housing element and ensure that housing fund expenditures remain reasonably related to the source of any housing fees deposited into the housing fund. The housing director shall also report on housing fund activities as part of the annual report required by Government Code Section 65400.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.040 - Housing fund—Use of funds.

A.

Monies deposited in the housing fund, along with any interest earnings on such monies, shall be used to increase, improve, and preserve the supply of housing and shelter serving Napa County's workforce and affordable to moderate, low, very low, and extremely low income households, including payment of those reasonable administrative costs described in subsection (B) below. Monies deposited in the housing fund may be utilized for, but are not limited to, the following purposes: new construction of affordable units; acquisition of land for the development of affordable housing; conversion of market rate units to affordable units; preservation of existing affordable units; rehabilitation of affordable units at risk of loss; promotion of affordable workforce housing such that Napa County workers can find suitable housing near their place of employment; subsidies for operating costs, including operating costs of emergency shelters, transitional housing, and farmworker housing, to maintain the existing supply of affordable units and shelters or to provide additional affordable units and shelters, where such shelters serve the County's workforce; subsidies for affordable housing in Affordable Housing (:AH) Combination Districts as further described in Chapter 18.82; provision of infrastructure, utilities, and other improvements so long as they are necessary for the construction of affordable units; and housing support services, such as fair housing services. Monies deposited in the housing fund may be used within incorporated cities located in Napa County consistent with the criteria established pursuant to subsection (B) of Section 18.107.030. Deed restrictions shall be recorded against parcels receiving housing funds and shall be effective for a minimum of forty years with respect to each affordable unit.

B.

Monies deposited in the housing fund may be used to cover reasonable administrative expenses not reimbursed through processing fees, including but not limited to reasonable staff, consultant, and legal expenses related to: 1) the establishment and/or administration of the housing fund; 2) the provision of housing fund assistance; and 3) the monitoring of compliance with conditions of such housing fund assistance. Monies may also be used to cover reasonable expenses for calculating, collecting, and accounting for fees paid into the housing fund. No portion of the housing fund may be diverted to other purposes by way of loan or otherwise.

C.

Expenditures by the housing director from the housing fund shall be controlled, authorized and paid in accordance with general county budgetary policies. Execution of contracts related to the use or administration of housing fund monies shall be in accordance with standard board policy.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.050 - Nonresidential developments—Housing fees and exemptions.

A.

Housing fees for nonresidential developments shall be established by resolution of the board of supervisors. Such fees shall not exceed the cost of mitigating the impact of nonresidential developments on the need for affordable housing in the county. The fees shall be established per gross square foot of nonresidential space and shall be based on at least the following nonresidential land use categories: office, retail, warehouse, industrial, and hotel. The board may also from time to time adopt by resolution a standardized list showing the specific uses within each nonresidential land use category and showing uses exempt from payment of housing fees.

B.

The board may periodically review the housing fees for nonresidential developments and adjust the housing fees by resolution. The housing fees shall be reviewed and, if appropriate, revised, at the time of each housing element update. The housing director and planning director shall jointly prepare a recommendation to the board for such fee revision.

C.

The following nonresidential developments are exempt from the payment of housing fees pursuant to this chapter:

1.

That portion of any nonresidential development located on property owned or leased by the county, the state of California, the United States of America, or any of its agencies, with the exception of such property not used exclusively for public purposes; or

2.

Any nonresidential development to the extent it has received a vested right to proceed without a housing fee pursuant to state law or is subject to a development agreement effective prior to July 1, 2009; or

3.

Any nonresidential development operated by a nonprofit organization to provide food storage, meal service and/or temporary shelter to the homeless; or

4.

Any nonresidential development involving no more than one total employee; or

5.

Any nonresidential development otherwise determined to be exempt pursuant to board resolution.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.060 - Nonresidential developments—-Housing fee requirement.

A.

No building permit shall be issued for any nonresidential development not otherwise exempt pursuant to subsection (C) of Section 18.107.050 until a housing fee is paid to the county. Where a building permit is not required, no discretionary county permit shall be issued for any nonresidential development not otherwise exempt pursuant to subsection (C) of Section 18.107.050 until a housing fee is paid to the county. Payment of the housing fee shall be made a condition of approval of each discretionary permit approved for a nonresidential development unless the project is exempt pursuant to subsection (C) of Section 18.107.050.

B.

The housing fee for nonresidential developments that include additions, new construction of gross square feet of nonresidential space, or the conversion of a residential use to a nonresidential use shall be calculated as follows:

Housing fee = (gross square feet of new nonresidential space) X (applicable fee by type of use)

The housing fee for the conversion of one nonresidential use to another nonresidential use shall be calculated as follows:

Housing fee = (housing fee for new use) - (housing fee for prior use) [not less than zero]

If the nonresidential development is in whole or part a replacement for nonresidential square footage demolished within one year prior to the filing of the application for the nonresidential development, the housing fee shall be calculated as follows:

Housing fee = (housing fee for addition or new construction of gross square feet) - (housing fee for gross square feet demolished) [not less than zero]

C.

As an alternative to payment of the housing fee set forth in subsection (A) above, an applicant for a nonresidential development may submit a request to mitigate the affordable housing impacts of such development through the construction of affordable units, either on-site or off-site, through the dedication of land, or through other means. The planning commission may approve or conditionally approve such an alternative if the planning commission determines, based on substantial evidence, that such alternative compliance will provide as much or more affordable housing at the same or lower income levels, is consistent with the county general plan and housing element, and will otherwise provide greater public benefit than would payment of the housing fee. Any affordable units constructed on-site or off-site shall comply with the provisions contained in Sections 18.107.110 through 18.107.140, as applicable.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.070 - Nonresidential developments—Application and fee setting procedures.

A.

An application for a building permit (or for a discretionary county permit if no building permit is required), for a nonresidential development shall not be deemed complete unless the application contains either: (1) a request for exemption pursuant to subsection (C) of Section 18.107.050 or an equivalency proposal as permitted by subsection (C) of Section 18.107.060, along with supporting information, or (2) all of the following: (a) a statement of the number of gross square feet contained in any addition, new construction of gross square feet, conversion of a residential use to a nonresidential use, or conversion of one nonresidential use to another nonresidential use, together with documentation sufficient to support the statement; (b) the intended use or uses for the nonresidential development by gross square feet; and (c) the gross square feet of any prior nonresidential use or any demolished nonresidential use. The amount of the housing fee shall be based upon the fee schedule in effect at the time of issuance of the permit for the nonresidential development.

B.

The planning director, with the concurrence of the housing director, shall determine the appropriate nonresidential land use category, shall calculate the amount of the housing fee based upon the adopted fee schedule, and shall so inform the building official or designee, who shall collect the required fee and deposit it into the housing fund. In the case of large, mixed-use nonresidential developments involving the simultaneous construction of different structures and/or different nonresidential uses, the planning director may utilize the fee schedule to create one mixed fee per square foot to be collected for all building permits in the project. In that case, the mixed fee shall be designed to approximate the revenue which would have been collected had the fee schedule been applied to each individual use in the project.

C.

The land use category for a nonresidential development shall be determined by the planning director based on an individualized determination only if:

1.

The adopted fee schedule so specifies; or

2.

The planning director determines that insufficient generalized information is available to permit a determination that the use falls within one of the specified use categories.

Any application for a nonresidential project where an individualized fee determination is required pursuant to this section shall be accompanied by information sufficient to enable the planning director to make a determination of employee density. The planning director's determination of employee density shall be based on: data concerning anticipated employee density for the project submitted by the applicant; employment surveys or other research on similar uses submitted by the applicant or independently researched by the planning director; or any other data or information the planning director determines relevant. Based on the evidence submitted, the planning director shall determine the most similar use category, or shall establish a mixed fee, as appropriate.

D.

An applicant may appeal the planning director's fee determination to the board of supervisors according to the provisions of Chapter 2.88 of the Napa County Code.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.080 - Residential projects—Basic inclusionary requirement.

A.

To mitigate the impacts of market rate residential projects on the need for affordable housing in Napa County, a portion of all new dwelling units in a residential ownership project shall be made available at an affordable sales price to moderate income households whose annual household income does not exceed one hundred twenty percent of median income, as follows:

Single-family detached-twenty percent

Attached single-family and common interest projects-seventeen percent

B.

For residential rental projects, housing fees shall be paid as specified in Section 18.107.090 to mitigate the project's impact on the need for affordable housing in the county, unless an equivalency proposal is approved pursuant to Section 18.107.100 or rental is approved pursuant to Section 18.107.110.

C.

Affordable units shall be comparable in number of bedrooms, exterior appearance and overall quality of construction to market rate units in the same residential project. Affordable units shall be dispersed throughout the

residential project, or, subject to the approval of the planning director, may be clustered within the residential project when this furthers affordable housing opportunities.

D.

The following residential projects are exempt from the affordable housing requirements in this Section 18.107.080 and in Section 18.107.090:

1.

Farmworker housing units of twelve hundred square feet or less; or

2.

Any residential project that is deed-restricted to be one hundred percent affordable to extremely low, very low, low income, or moderate income households, except for managers' units, and which meets the requirements of Section 18.107.140; or

3.

Multi-family or single room occupancy residential projects, which propose that at least twenty percent of the total units be available at affordable rent or affordable sales prices to very low or low income households; and

4.

Any density bonus units, as required by Government Code Section 65915.

E.

Compliance with this chapter shall be made a condition of approval of each permit approved for a residential development unless the project is exempt pursuant to subsection (D) above.

(Ord. No. 1334, § 3, 1-19-2010)

(Ord. No. 1386, § 2, 12-10-2013; Ord. No. 1491, § 16, 6-4-2024)

18.107.090 - Residential projects—Housing fees.

A.

Housing fees for residential projects shall be established by resolution of the board of supervisors. Such fees shall not exceed the cost of mitigating the impact of market rate residential projects on the need for affordable housing in the county. The fees shall be established per gross square foot of residential floor area for the market rate units in a residential development.

B.

The board may periodically review the housing fees for residential projects and adjust the housing fees by resolution. The housing fees shall be reviewed and, if appropriate, revised at the time of each housing element update. The housing director and planning director shall jointly prepare a recommendation to the board for such fee revision.

C.

An applicant for any residential ownership project with four or fewer dwelling units may elect to either build one affordable unit or pay a housing fee for each dwelling unit.

D.

Housing fees shall be paid for residential projects in the following circumstances:

1.

For any residential rental project, a housing fee shall be paid upon issuance of a building permit for each dwelling unit in the residential rental project, unless an equivalency proposal is approved pursuant to Section 18.107.100 or rental is approved pursuant to Section 18.107.110.

2.

For any residential ownership project with four or fewer dwelling units where the applicant has elected to pay housing fees, a housing fee shall be paid upon issuance of a building permit for each dwelling unit in the residential ownership project.

3.

For any residential ownership project with five or more dwelling units where the calculations in subsection (A) of Section 18.107.080 above result in a fractional dwelling unit, a housing fee shall be paid upon issuance of each building permit for those "extra" market rate dwelling units for which an affordable unit was not constructed (based on the floor area of each such "extra" market rate unit), unless the applicant elects to construct an additional affordable unit on-site, or performs an equivalent action approved pursuant to Section 18.107.100.

E.

The amount of any housing fee payable under this section shall be based upon the fee schedule in effect at the time of issuance of the building permit for the dwelling unit to which the fee relates. The planning director, with the concurrence of the housing director, shall calculate the amount of any housing fee based upon the adopted fee schedule, and shall so inform the building official or designee, who shall collect the required fee and deposit it into the housing fund. The applicant may appeal the planning director's fee determination to the board of supervisors according to the provisions of Chapter 2.88 of the Napa County Code.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.100 - Residential projects—Equivalency proposals permitted.

As an alternative to the construction of on-site affordable units required by Section 18.107.080, or to the payment of housing fees pursuant to Section 18.107.090, an applicant for a residential project may submit a request to mitigate the affordable housing impacts of such project through the construction of affordable units off-site, through the dedication of land for affordable housing, or through other means. The planning commission may approve or conditionally approve such an alternative if the planning commission determines, based on substantial evidence, that such alternative compliance will provide as much or more affordable housing at the same or lower income levels, is consistent with the county general plan and housing element, and will otherwise provide greater public benefit than would provision of the affordable housing on-site.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.110 - Residential projects—Rental permitted if consistent with Costa-Hawkins Act.

A.

As an alternative to providing affordable ownership units on-site as required by Section 18.107.080, or paying housing fees pursuant to Section 18.107.090, an applicant may propose to provide twelve percent of the dwelling units in the residential project as rental dwelling units affordable to low income households. To ensure compliance with the Costa-Hawkins Act (Chapter 2.7 of Title 5 of Part 4 of Division 3 of the Civil Code), the county may only approve such a proposal if the applicant agrees in a rent regulatory agreement with the county to limit rents in consideration for a direct financial contribution or a form of assistance specified in Chapter 4.3 (commencing with Section 65915) of Division 1 of Title 7 of the Government Code.

B.

The rent regulatory agreement with the county shall include provisions for sale of affordable units and relocation benefits for tenants of the affordable units if the owner of the residential project later determines to offer any affordable units in the residential project for sale. If dwelling units in the residential project are sold, the applicant shall provide as many ownership affordable units at an affordable sales price as required by Section 18.107.080. At the time of sale, resale restrictions, deeds of trust and/or other documents acceptable to the planning director shall be recorded against the affordable ownership dwelling units for a minimum term of forty years, as required by Section 18.107.140.

C.

For each rental affordable unit provided pursuant to this section, the owner may be required to pay to the county an annual monitoring fee for the term of required affordability that does not exceed the county's costs to monitor the affordable unit, if such a fee is adopted by resolution of the board of supervisors.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.120 - Residential projects—County incentives.

A.

Residential projects that include the construction of affordable units in conformance with Sections 18.107.080, 18.107.100, or 18.107.110 are eligible for the following county incentives:

1.

Application fees for building permits shall be waived for the affordable units.

2.

Subject to the approval of the planning director, the square footage of the affordable units and interior features in affordable units need not be the same as those in market rate units in the same residential project, so long as they are of good quality and are consistent with contemporary standards for new housing.

3.

In a residential project which contains single-family detached homes, affordable units may be attached dwelling units.

4.

The county shall expedite permit processing.

B.

If an applicant requests a state density bonus or state incentives pursuant to Sections 18.107.070 and 18.107.080, the incentives listed in this section may be provided only if each is individually requested as a state incentive pursuant to Section 18.107.070.

C.

Each of these incentives is a regulatory incentive that results in identifiable, financially sufficient, and actual cost reductions and is a form of assistance specified in Chapter 4.3 (commencing with Section 65915) of Division 1 of Title 7 of the Government Code.

(Ord. No. 1334, § 3, 1-19-2010)

(Ord. No. 1495, § 45, 9-24-2024)

18.107.130 - Residential projects—Application and review procedures.

A.

An application for a discretionary approval or for a building permit, if no discretionary approval is required, for a residential project shall include an affordable housing plan if the residential project includes on-site affordable housing required by Section 18.107.080, an equivalency proposal as permitted by Section 18.107.100, or a rental proposal as permitted by Section 18.107.110. The affordable housing plan shall include a site plan depicting the number and location of all affordable units, phasing of affordable units in relation to market rate units, and such other information as may be required by the planning director.

B.

Any affordable housing plan shall be considered by, and acted upon, by the approval body with authority to approve the residential project. Before approving the affordable housing plan, the approval body shall find that the affordable housing plan conforms to the requirements of this Chapter 18.107. The planning commission may approve an equivalency proposal pursuant to Section 18.107.100 or rental pursuant to Section 18.107.110 if the affordable housing plan conforms to the requirements of this chapter. An applicant may appeal decisions made by the planning commission pursuant to this subsection (B) of Section 18.107.130 to the board of supervisors according to the provisions of Chapter 2.88 of the Napa County Code.

C.

If an affordable housing plan is approved, applicants shall enter into an affordable housing or rent regulatory agreement with the county, in a form acceptable to the planning director and county counsel. Such agreements shall be legally binding agreements between the applicant and the county to ensure that the requirements of this chapter are satisfied. The executed agreements shall be recorded against the residential project prior to final or parcel map approval, or, where a map is not being processed, prior to issuance of building permits for the residential project. The agreements shall be binding on all future owners and successors in interest.

D.

Unless otherwise permitted pursuant to the terms of a recorded affordable housing or rent regulatory agreement, all required affordable units shall be constructed prior to or concurrently with the construction of market rate units. No temporary or permanent certificate of occupancy for any new market rate unit in a residential project shall be issued until permanent certificates of occupancy have been issued for the affordable units required by Section

18.107.080 or the applicant has satisfactorily performed one of the equivalent actions set forth in Sections 18.107.90 through 18.107.110. Release of utilities shall not be authorized for any residential project until notification is received from the planning director that all requirements of this chapter have been met.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.140 - Residential projects—Continued affordability

A.

Prior to the issuance of certificates of occupancy for affordable units, rent regulatory agreements, resale restrictions, deeds of trust, and/or other documents, as appropriate, all of which must be acceptable to the housing director and county counsel and consistent with the requirements of this chapter, shall be recorded against parcels having such affordable units and shall ensure that each affordable unit remains affordable to the same income level for a minimum of forty years. Any rent regulatory agreement shall include the applicant's agreement to limit rents in consideration for a direct financial contribution or a form of assistance specified in Chapter 4.3 (commencing with Section 65915) of Division 1 of Title 7 of the Government Code.

B.

At the time of resale of any owner-occupied affordable unit, resale restrictions, deeds of trust and/or other documents acceptable to the housing director shall be recorded against such affordable unit for a new minimum term of forty years.

C.

No household shall be permitted to occupy an affordable unit, or to purchase an affordable unit for owneroccupancy, unless the county or its designee has approved the household's eligibility. If the county or its designee maintains a list of eligible households, households selected to occupy affordable units shall be selected first from that list to the extent provided in the affordable housing agreement, rent regulatory agreement, or resale restrictions.

D.

For each owner-occupied affordable unit provided pursuant to this chapter, the owner may be required to pay to the county an administrative transfer fee to defray the costs to the county of any change of ownership during the term of required affordability, if such a fee is adopted by resolution of the board of supervisors.

Editor's note— Ord. No. 1495, § 47, adopted September 24, 2024, repealed § 18.107.160, which pertained to Affordable Housing and Incentives.

18.107.170 - State incentives for affordable housing—Application procedures and development standards.

The purpose of this section and Section 18.107.180 is to implement state density bonus law (Government Code Section 65915 et seq.).

A.

An applicant for a "housing development" as defined in state density bonus law shall be eligible for a density bonus and other regulatory benefits that are provided by state density bonus law when the applicant seeks and agrees to provide housing as specified in Government Code Section 65915, or in Government Code Section 65195.5, or successor provisions. The density bonus calculations shall be made in accordance with state density bonus law.

B.

All requests for density bonuses, incentives, parking reductions, and waivers shall be submitted concurrently with the application for the first discretionary permit or other permit required for the housing development and shall be processed concurrently with such application. In accordance with state law, neither the granting of an incentive, nor the granting of a density bonus, shall be interpreted, in and of itself, to require a general plan amendment, zoning change, or other discretionary approval or the waiver of the provisions of a county ordinance unrelated to development standards.

C.

An applicant's request for any density bonuses, incentives, parking reductions, and/or waivers permitted by state density bonus law shall include the required fee and the following minimum information:

1.

For a requested density bonus:

a.

Summary table showing the maximum number of dwelling units permitted by the zoning and general plan excluding any density bonus units, proposed target units by income level, proposed bonus percentage, number of density bonus units proposed, total number of dwelling units proposed on the site, and resulting density in units per acre.

b.

Subparagraph of Government Code Section 65915(b)(1) under which the housing development qualifies for a density bonus and reasonable documentation demonstrating that the housing development is eligible for a bonus under that subparagraph.

c.

Where the housing development is seeking an additional bonus, the subparagraph of Government Code Section 65915(v)(1) under which the housing development qualifies for an additional density bonus and reasonable documentation demonstrating that the housing development is eligible for the additional bonus under that subparagraph.

d.

A tentative map or preliminary site plan, drawn to scale, showing the number and location of all proposed units, designating the location of proposed target units and density bonus units.

e.

The zoning and general plan designations and assessor's parcel number(s) of the housing development site.

f.

A description of all dwelling units existing on the site in the five-year period preceding the date of submittal of the application and identification of any units rented in the five-year period; subject to any form of rent control through a public entity's valid exercise of its police power; or subject to a recorded covenant ordinance, or law restricting rents to levels affordable to households of lower or very low income.

g.

If dwelling units on the site are currently rented, income and household size of all residents of currently occupied units, if known. If any dwelling units on the site were rented in the five-year period but are not currently rented, the income and household size of residents occupying the dwelling units when the site contained the maximum number of dwelling units, if known.

h.

The phasing of the construction of the target units in relation to the nonrestricted units in the housing development.

i.

A marketing plan for the target units, as well as an explanation of the methods to be used to verify tenant and/or buyer incomes and to maintain affordability of the target units. The density bonus housing plan shall specify a financing mechanism for ongoing administration and monitoring of the target units.

j.

If a density bonus is requested for a land donation, the location of the land to be dedicated, proof of site control, and reasonable documentation that each of the requirements included in Government Code Section 65915 (g) can be met.

2.

Requested incentives or concessions as defined in state density bonus law. The number of incentives that may be requested shall be based upon the number the applicant is entitled to under state density bonus law. The application shall include the following minimum information, shown on a site plan (if appropriate):

a.

Explanation of the number of incentives the housing development is entitled to.

b.

The county's usual regulation and each requested regulatory incentive or concession.

c.

Except where mixed-use zoning is proposed as a concession or incentive, reasonable documentation to show that any requested incentive will result in identifiable and actual cost reductions to provide for affordable housing costs or rents.

d.

If approval of mixed-use zoning is proposed, reasonable documentation that nonresidential land uses will reduce the costs of the housing development, that the nonresidential land uses are compatible with the housing development and the existing or planned development in the area where the proposed housing development will be located, and that mixed-use zoning will provide for affordable housing costs and rents.

3.

Requested waivers. For each waiver requested, the applicant shall show on a site plan and in a table, the county's required development standard and the requested development standard.

4.

Parking reductions. The application shall include a table showing parking required by the zoning regulations, parking proposed under Government Code Section 65915(p), and reasonable documentation that the project is eligible for the requested parking reduction.

5.

Density bonus or incentive for a child care facility in a housing development. The application shall include reasonable documentation that all of the requirements included in Government Code Section 65915(h) can be met.

6.

Density bonus or incentive for a condominium conversion. The application shall include reasonable documentation that all of the requirements included in Government Code Section 65915.5 can be met.

7.

Commercial density bonus. Evidence that the project qualifies for a commercial density bonus under the provisions of Government Code Section 65915.7, including but not limited to inclusion of a partnered housing agreement.

D.

Density bonus calculations.

1.

In determining the total number of units to be granted, each component of any density calculation, including base density and bonus density, resulting in fractional units shall be separately rounded up to the next whole number. When calculating the number of target units needed to qualify for a given density bonus, any fractions of affordable target units shall be rounded up to the next whole number.

2.

Except where a housing development is eligible for an additional bonus pursuant to Government Code Section 65915(v), each housing development is entitled to only one density bonus. If a housing development qualifies for a density bonus under more than one category, the applicant shall identify the category under which the density bonus is requested to be granted.

In determining the number of target units required to qualify a housing development for a density bonus pursuant to state density bonus law, units added by a density bonus are not included in the calculations. Any on-site units that satisfy the county's inclusionary housing requirements in this Chapter 18.107 and are required to be constructed concurrently with the housing development may qualify the housing development for a density bonus if those units meet the requirements of state density bonus law. Payment of fees or in lieu of providing target units under this Chapter 18.107 does not qualify a housing development for a density bonus.

4.

The applicant may elect to accept a lesser percentage of density bonus than the housing development is entitled to, or no density bonus, but no reduction will be permitted in the percentages of target units required by state density bonus law. Regardless of the number of target units, no housing development shall be entitled to a density bonus greater than what is authorized under state density bonus law.

5.

Nothing in this chapter requires the provision of direct financial incentives from the county for the housing development, including, but not limited to, the provision of financial subsidies, publicly owned land, fee waivers, or waiver of dedication requirements. The county, at its sole discretion, may choose to provide such direct financial incentives.

E.

Development standards.

1.

Target units shall be comparable in exterior appearance and overall quality of construction to market rate units in the same housing development. Interior finishes and amenities may differ from those provided in the market rate units, but neither the workmanship nor the products may be of substandard or inferior quality as determined by the county.

2.

To comply with fair housing laws, the target units shall contain the same proportional mix of bedroom sizes as the market-rate units. In mixed-income buildings, the occupants of the target units shall have the same access to the common entrances and to the common areas, parking, and amenities of the project as the occupants of the market-rate housing units, and the target units shall be located throughout the building and not isolated on one floor or to an area on a specific floor.

18.107.180 - State incentives for affordable housing—Review procedures and affordable housing agreements.

All requests for density bonuses, incentives, parking reductions, and waivers shall be considered and acted upon by the approval body with authority to approve the residential project, with right of appeal to the board of supervisors, if applicable.

A.

To ensure that an application conforms with the provisions of state density bonus law, the staff report presented to the decision-making body shall state whether the application conforms to the requirements of state density bonus law, as applicable:

1.

A finding that the residential project is eligible for the density bonus and any incentives, parking reductions or waivers requested, and includes any affordable housing required to replace units rented or formerly rented to very low- and low-income households as required by California Government Code Sections 65915(c)(3) and 66300.5 et seq.

2.

A finding that if an incentive is requested, reasonable documentation has been presented showing that any requested incentive will result in identifiable and actual cost reductions to provide for affordable housing or costs or rents; except that, if a mixed-use development is requested, the application must instead meet all of the requirements of Government Code Section 65915(k)(2).

3.

If the density bonus is based all or in part on donation of land, a finding that all the requirements included in Government Code Section 65915(g) have been met.

4.

If the density bonus or incentive is based all or in part on the inclusion of a child care facility or condominium conversion, a finding that all the requirements included in Government Code Section 65915(h) or 65915.5, as applicable, have been met.

5.

If a parking reduction is requested, a finding that the housing development is eligible for any requested parking reductions under Government Code Section 65915(p).

6.

If a waiver is requested, a finding that the development standards for which the waiver is requested would have the effect of physically precluding the construction of the residential project with the density bonus and incentives permitted.

7.

If a commercial development bonus is requested, a finding that the development is eligible for the bonus under Government Code Section 65915.7.

B.

If the housing development is eligible for the incentives requested, the decision-making body may deny an application for an incentive only if it makes one of the following written findings, supported by substantial evidence:

The incentive does not result in identifiable and actual cost reductions, consistent with Government Code Section 65915(k), to provide for affordable sales prices or affordable rents; or

2.

The incentive would have a specific, adverse impact upon public health or safety or the physical environment or on real property listed in the California Register of Historic Resources, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the residential project unaffordable to low and moderate income households. For the purpose of this subsection, "specific adverse impact" means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the residential project was deemed complete; or

3.

The incentive is contrary to state or federal law.

C.

If the housing development is eligible for the waivers requested, the decision-making body may deny a request for a waiver only if it makes one of the following written findings, supported by substantial evidence:

1.

The waiver would have a specific, adverse impact upon public health or safety or the physical environment, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the residential project unaffordable to low and moderate income households. For the purpose of this subsection, "specific adverse impact" means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the residential project was deemed complete; or

2.

The waiver would have an adverse impact on real property listed in the California Register of Historic Resources; or

3.

The waiver is contrary to state or federal law.

D.

If the housing development is eligible for a child care bonus, the decision-making body may deny an application for a density bonus or incentive that is based on the provision of child care only if it makes a written finding, based on substantial evidence, that the county already has adequate child care facilities.

E.

If any density bonus, incentive, parking reduction, or waiver is approved pursuant to state density bonus law, the applicant shall enter into an affordable housing agreement with the county, in a form acceptable to the planning director and county counsel, to be executed by the county administrator or designee, to ensure compliance with state density bonus law. The affordable housing agreement shall be a legally binding agreement between the applicant and the county to ensure that the requirements of this chapter are satisfied and may be combined with the affordable housing agreement required in Section 18.107.130. The executed affordable housing agreement

shall be recorded against the residential project prior to final or parcel map approval, or, where a map is not being processed, prior to issuance of building permits for the residential project. The affordable housing agreement shall be binding on all future owners and successors in interest.

F.

For rental projects, the agreement shall require the continued affordability of all rental units that qualified the applicant for the receipt of the density bonus, incentive, waiver, or parking reduction for a minimum of fifty-five years or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program; shall identify the type, size, and location of each target unit; shall specify the eligible occupants; shall specify phasing of the target units in relation to the market-rate units; and shall contain other relevant provisions approved by county counsel. Rents for the lower income density bonus units shall be set at an affordable rent as defined in state density bonus law.

G.

For for-sale projects, the affordable housing agreement shall require that the initial purchasers of those for-sale units that qualified the applicant for the receipt of the density bonus, incentive, waiver, or parking reduction are persons and families of lower or moderate income, as applicable, or if any for-sale unit is not purchased by an income-qualified household within one-hundred eighty days after the issuance of the certificate of occupancy, then the unit(s) must be sold pursuant to a contract that satisfies the requirements of Revenue and Taxation Code Section 402.1(a)(10) to a qualified non-profit housing corporation as defined in state density bonus law. The units shall be offered at an affordable housing cost, as that cost is defined in Health and Safety Code Section 50052.5; and the agreement shall contain other relevant provisions approved by county counsel. The affordable housing agreement shall require the continued affordability of the for-sale units for forty-five years.

H.

Where a density bonus, waiver, or parking reduction is provided for a market-rate senior housing development with no target units, the applicant shall enter into a restrictive covenant with the county, running with the land, in a form approved by county counsel, to be executed by the county administrator or designee, to require the housing development to be operated as "housing for older persons" consistent with state and federal fair housing laws.

I.

Unless otherwise permitted pursuant to the terms of a recorded affordable housing agreement, all required target units shall be constructed prior to or concurrently with the construction of market rate units. No temporary or permanent certificate of occupancy for any new market rate unit in a residential project shall be issued until permanent certificates of occupancy have been issued for the required target units. Release of utilities shall not be authorized for any residential project until notification is received from the planning director that all requirements of this chapter have been met.

(Ord. No. 1495, § 49, 9-24-2024)

18.107.190 - General—No conflict with state law.

If any section of this chapter conflicts with Government Code Section 65915 or other applicable state law, state law shall supersede this chapter.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.200 - General—Refunds.

Whenever an applicant pays the housing fees established by this chapter and thereafter fails to proceed with the development in a timely manner so that the privilege of doing so has elapsed, the county shall refund any fees paid by the applicant if the applicant submits a written request for a refund to the planning director within ninety days of the date when the privilege of proceeding with the development elapsed.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.210 - General—Enforcement.

A.

It shall be a misdemeanor for any person to sell or rent an affordable unit or target unit at a sales price or rent exceeding the maximum sales price or rent allowed by this chapter, or to a household not qualified to purchase or rent an affordable unit or target unit pursuant to this chapter.

B.

The office of county counsel or the district attorney, as appropriate, shall be authorized to enforce the provisions of this chapter and all affordable housing agreements, rent regulatory agreements, resale controls, and all other agreements placed on affordable units or target units hereunder, by civil action and any other proceeding or method permitted by law.

C.

Failure of any official to fulfill the requirements of a provision of this chapter shall not excuse any applicant from fulfilling the remaining requirements of this chapter.

(Ord. No. 1334, § 3, 1-19-2010)

18.107.220 - General—Waiver.

A.

As part of an application for the first approval of a residential project or nonresidential development, an applicant may apply for a reduction, adjustment, or waiver of the requirements of this chapter based upon a showing that applying the requirements of this chapter would result in an unconstitutional taking of property or would result in any other unconstitutional result. The applicant shall set forth in detail the factual and legal basis for the claim, including all supporting technical documentation, and shall bear the burden of presenting the requisite evidence to demonstrate the alleged unconstitutional result. The county may assume each of the following when applicable:

1.

The applicant will benefit from the incentives set forth in the county code; and

2.

The applicant will be obligated to provide the most economical affordable units feasible in terms of financing, construction, design, location and tenure.

B.

The approval authority, based upon legal advice provided by or at the behest of county counsel, may approve a reduction, adjustment, or waiver if the approval authority determines that applying the requirements of this chapter would effectuate an unconstitutional taking of property or otherwise have an unconstitutional application to the property. The reduction, adjustment, or waiver shall be approved only to the extent necessary to avoid an unconstitutional result, after adoption of written findings, and based on legal analysis and the evidence. If a reduction, adjustment, or waiver is granted, any change in the residential project shall invalidate the reduction, adjustment, or waiver, and a new application shall be required for a reduction, adjustment, or waiver pursuant to this section.

(Ord. No. 1334, § 3, 1-19-2010)

Chapter 18.108 - CONSERVATION REGULATIONS

18.108.010 - Purpose.

A.

The purpose and intent of these regulations is to protect the public health, safety and community welfare, and to otherwise preserve the natural resources of the county of Napa. Further, these regulations are intended to ensure the continued long-term viability of county agricultural resources by protecting county lands from excessive soil loss which if unprotected could threaten local water quality and quantity and lead ultimately to loss of economic productivity. These regulations are also intended to provide greater environmental protection for natural environmental resources, particularly agricultural lands, forests, wildlife habitat, and water. These regulations have been developed in general accord with the policies and principles of the general plan, as specified in the agricultural preservation and land use element and the conservation element.

B.

It is furthermore intended that these regulations accomplish the following:

1.

Minimize cut, fill, earthmoving, grading operations and other such man-made effects in the natural terrain;

2.

Minimize soil erosion caused by human modifications to the natural terrain;

3.

Maintain and improve, to the extent feasible, existing water quality by regulating the quantity and quality of runoff entering local watercourses;

4.

Preserve riparian and wetland areas and other natural habitat by controlling development near streams, rivers and wetlands;

5.

Encourage development which minimizes impacts on existing land forms, avoids steep slopes, and preserves existing vegetation and unique geologic features;

6.

Protect drinking water supply reservoirs in sensitive domestic water supply drainages from sediment, turbidity, and pollution through vegetation retention and no-development buffers around municipal reservoirs; and

7.

Reduce the loss of vegetation by increasing protections for vegetation canopy cover, requiring minimum mitigation requirements and prioritizing areas eligible for mitigation.

C.

It is not the intent of these regulations to provide that compliance with these regulations shall provide a defense to a charge of violating Section 5650 of the California Fish and Game Code.

D.

It is also the intent of these regulations to further the intent and purpose of Section 1600 of the California Fish and Game Code.

E.

Napa County has implemented the National Pollution Discharge Elimination System (NPDES) program, which requires the County to ensure that stormwater and erosion control measures are provided for all applicable structural (i.e., nonagricultural) projects. As such, technical aspects of providing erosion control measures for structural projects shall be administered by the planning department via the NPDES program. The remaining applicable requirements of this chapter shall still apply to structural projects. For agricultural projects (which are not covered by the NPDES program), all the requirements of this chapter remain in full effect.

(Ord. 1259 § 1, 2005: Ord. 1219 § 1, 2003: Ord. 991 § 1 (part), 1991: prior code § 12450)

(Ord. No. 1438, § 1, 4-9-2019)

18.108.020 - General provisions.

A.

Applicability. These regulations shall apply to all zoning districts within Napa County and to all uses that may involve earthmoving activity permitted in such districts, with or without use permits, except as may be specifically provided in this chapter. In the event of conflicts among the regulations in this chapter and those elsewhere in this title, the regulations in this chapter shall prevail except where specifically noted otherwise in this chapter.

B.

Relationship to the Review of Tentative Parcel Maps and Subdivision Maps. To the greatest extent feasible, no tentative map, parcel map or final map shall be approved which will create lots which would necessitate approval of exceptions to these regulations pursuant to Section 18.108.040. Where a division of land would require an exception to these regulations, precise building envelopes shall be specified on the tentative maps, parcel maps and final maps, to ensure that the maximum feasible conformance with this chapter can be attained and maintained over time.

C.

Vegetation Retention Requirements. In the AW zoning district, a minimum of seventy percent vegetation canopy cover as configured on the parcel existing on June 16, 2016 shall be maintained as part of any use involving earthdisturbing activity. Two or more contiguous parcels held and maintained under common ownership or legal control at the time the plan is submitted may be considered combined and treated as one holding for purposes of compliance with the vegetation requirements in this section; provided that: (1) the total vegetation proposed for clearing would not be greater than what could be cleared if each contiguous parcel was treated an individual unit; (2) a report prepared by a qualified professional biologist is submitted to the director which concludes that the proposed vegetation clearing would not result in greater impacts to biological resources than what would occur if the combined parcels were treated as individual units; and (3) a perpetual protective easement or a perpetual deed restriction is recorded for each parcel describing the amount of vegetation to be retained on each of the parcels.

D.

Vegetation Removal Mitigation. In the AW zoning district, the removal of any vegetation canopy cover shall be mitigated by permanent replacement or preservation of comparable vegetation canopy cover, on an acreage basis

at a minimum 3:1 ratio unless otherwise set forth below. The location for replacement or preservation may be prioritized as follows:

1.

Replacement or preservation shall first be accomplished on-site on lands with slopes of thirty percent or less and outside of stream and wetland setbacks.

2.

If sufficient vegetation canopy cover cannot be reasonably accomplished under subsection (D)(1) of this section, on-site preservation or replacement may occur on slopes greater than thirty percent and up to fifty percent in areas that result in the highest biological and water quality protections as determined by the director.

3.

If sufficient vegetation canopy cover cannot be reasonably accomplished under subsection (D)(1) or under subsection (D)(2) of this section, off-site replacement or preservation may occur if it is within the same watershed and the habitat is of the same or better quality as determined by the director.

4.

Replacement of vegetation canopy cover may occur within stream setbacks at a minimum 2:1 preservation ratio where a restoration plan prepared by a qualified professional biologist has been approved by the director, and where consistent with Section 18.108.025 (D) as determined by the director.

5.

Alternatively, the removal of any vegetation canopy cover may be mitigated by permanent replacement or preservation of comparable vegetation canopy cover, on an acreage basis at a minimum 2:1 ratio, where the project includes substantial public benefits as determined by the director.

6.

Non-native species shall not be subject to the vegetation canopy cover replacement or preservation requirements under subsection (D) of this section.

E.

Preserved Vegetation Canopy Cover. Preserved vegetation canopy cover shall be enforceably restricted with a perpetual protective easement or perpetual deed restriction preserving and conserving the preserved vegetation canopy cover.

(Ord. 991 § 1 (part), 1991: prior code § 12452)

(Ord. No. 1438, § 2, 4-9-2019)

18.108.025 - General provisions—Intermittent/perennial streams.

18.108.060 - Slope regulations—Prohibited uses.

A.

Uses Prohibited Without an Exemption or an Exception. To minimize the risks associated with project development in areas characterized by steep slopes, high erosion potential, unstable soils, combustible vegetation and other sensitive environmental resource areas as defined by Section 18.08.270 or designated in the conservation element, the recreation and open space element and the safety element of the general plan, no construction, improvement, grading, earthmoving activity or vegetation removal associated with the development or use of land shall take place on those parcels or portions thereof generally having a slope of thirty percent or greater as defined in Section 18.108.060(C) unless exempt under Sections 18.108.050 or 18.108.055 or unless an exception through the use permit process is granted pursuant to Section 18.108.040.

B.

Uses Prohibited Without an Exemption. No structure, improvement, grading, earthmoving activity, vegetation removal or development shall be permitted on a slope greater than fifty percent unless exempt under Section 18.108.050 or 18.108.055 of this chapter.

C.

Slope Determination Methodology. The percent slope for a proposed project is described as the ratio of the vertical distance to the horizontal distance, or the elevation change in feet divided by distance in feet measured perpendicular to the contours. The percent slope of the development area described herein is the natural slope of the existing terrain, not the finished or proposed percent slope resulting from the project.

1.

Structural Development.

a.

The percent slope of the structural development area is measured perpendicular to the contours across the building pad and driveway when the driveway is less than 50 feet in length. The slope determination shall be made by evaluating a plot plan identifying contour intervals of two (2) to five (5) feet, with a scale of 1" = 20' or better.

b.

When a driveway exceeds 50 feet in length, the slope of the structural development area is measured perpendicular to the contours across the foundation and area of ground disturbance around the foundation of the proposed structure. The driveway slope shall be measured separately as identified in subsection (C)(2) of this section.

2.

Road/Access Development. The analysis for slope determination for grading involving a roadway longer than 50 feet shall be determined using the following criteria and shall be based on mapping with a maximum scale of 1" = 50' with contour intervals of five (5) feet or less.

a.

The approximate centerline of the proposed roadway shall be stationed with 0+00 being assigned to the point where grading commences.

b.

Cross sections shall be taken at each station 100 feet apart, i.e., 1+00, 2+00 etc., extending to the outer limits of grading. When the road is less than 200 feet long, then three equally spaced cross sections shall be taken. The axis of each cross section shall be perpendicular to the contours pertinent to the section. These sections shall be drawn to a scale of 1" = 10' horizontal and vertical. An average cross section slope shall be calculated by dividing the difference in elevation of the cut and/or fill catch points by the intervening distance.

c.

The average slope of the project is to be determined by averaging all of the cross sections excluding those measured at less than five percent slope. The average slope shall not exceed thirty percent and no more than three (3) cross sections shall exceed fifty percent.

3.

General Land Clearing. When earth-disturbing activities, land clearing or grading involves 30 acres or less, the slope of contiguous lands (i.e., not separated by streams, roads, or noncleared areas) is measured from a map with a scale of 1" = 100' (maximum) with contour intervals of 20 feet, or at a contour interval acceptable to the director. When earth disturbing activities, grading or removal of vegetation involves greater than 30 acres, a contour interval of two (2) feet in the Napa River Watershed and five (5) feet in other areas shall be applied. If any portion within the contiguous area to be cleared is greater than thirty percent slope, then the following standards apply:

a.

If the total area of any contiguous earthmoving, grading or land clearing is larger than one (1) acre, subareas up to one acre in size in the thirty to fifty percent slope range may be cleared subject to administrative approval by the director. No earthmoving activities, grading or land clearing exceeding one (1) acre shall occur on slopes greater than thirty percent.

b.

If the total contiguous area to of proposed earthmoving, land clearing and/or grading is less than one (1) acre, no more than ⅓ (one third) of the project area to be cleared or graded may exceed thirty percent slope, subject to administrative approval by the director.

Maintenance. The property owner is responsible for insuring that the erosion control measures installed operate properly and are effective in reducing to a minimum erosion and related sedimentation. The property owner shall either personally or have personnel inspect and repair/clean as necessary the erosion control measures installed at least weekly during the period between October 1st and April 1st of each year. Moreover, the property owner shall either be on-site or have personnel on site as required when it is raining to inspect the erosion control measures present and take those actions necessary to keep them functioning properly.

C.

Monitoring. For projects disturbing more than one acre of land or with an average slope greater than fifteen percent, the property owner shall implement, prior to the first winter rains after installation of the planned facilities is commenced, a permanent, on-going program of self-monitoring of ground cover condition, and erosion control facility operation. The ground cover monitoring shall follow the procedures promulgated by the Natural Resources Conservation Service (NRCS) for determining rangeland condition for hydrologic assessment.

For projects involving disturbance of more than forty acres of land or containing areas with slopes greater than thirty percent totaling a quarter acre or more, an Annual Erosion Control Plan Operation Status Report specifying ground cover condition and how the erosion control measures involved are operating shall be provided to the director and, if in a sensitive domestic water supply drainage, the owner/operator(s) of any public-serving drinking water supply reservoir present by September 1st of each year. This report shall specify the proposed management and cultural measures to be used the following year to return or maintain the ground cover in good condition in all

parts of the area disturbed including vineyard avenues and any remedial actions that will be taken to get the other erosion control measures present to operate in such a manner as to minimize erosion and resultant sedimentation.

D.

Failures. The following provisions shall apply where erosion control measures have failed or are in imminent danger of failing.

1.

Property Owner Duties - Temporary Measures. The property owner shall:

a.

Notify the director in writing of the failure or pending failure of any erosion control measures within twenty-four hours of discovery and indicate the temporary measures taken to stabilize the situation; and

2.

Property Owner Duties - Permanent Remedial Measures. The property owner shall:

a.

Submit within ninety-six hours after the discovery of a failure or pending failure:

i.

An engineered plan for the remedial measures necessary to permanently correct the problem and an engineer's estimate of the cost thereof, and

ii.

A plan for cleanup of the damage done with an engineer's estimate for the cost of this work;

b.

Resubmit to the county, within forty-eight hours of the time comments are received from the independent engineer hired by the county to review the temporary measures installed, the plan, and engineer's cost estimates revised plans and estimates;

c.

Pay the county the costs of this review within forty-eight hours of demand;

d.

Post a security in one of the forms specified by subsection (A)(1) through (4) of Section 17.38.030 in the amount equal to one hundred percent of the accepted estimated total cost to do the work required to correct the situation

and cleanup the damage done within forty-eight hours of demand; and

e.

Insure that the revised plan prepared is fully implemented within ninety-six hours of its approval.

The time frames specified in this subsection are maximums. The director may in the case of an immediate threat to public health and/or safety require performance in shorter time periods.

3.

Plan Preparer Duties. The plan preparer shall provide a notice to the county within twenty-four hours of full implementation of the plan prepared to permanently correct the problem certifying that the measures shown have been installed in conformance with said plan and related specifications.

4.

Noncompliance. Failure to adhere to the provisions of subsections (D)(1) and (2) above may be considered a threat to public health and safety. The director may in such instances take immediate action without further notice or hearing to remedy the situation and bill the property owner for the remedial work done. The director shall keep an itemized account of the costs incurred in remedying the situation. The board shall conduct a hearing on the costs in accordance with Sections 1.20.090 through 1.20.130 of this code and shall give the property owner an opportunity to object to the costs prior to recording a lien against the property or pursuing other cost-recovery actions.

Inspection.

1.

Each project requiring an erosion control plan that has not received a final inspection and been found complete by the director shall be inspected by the county or its agent after the first major storm event of each winter until the project has been completed and stable for three years. If it is found that the erosion control program implemented is not functioning properly or is ineffective the property owner shall take such remedial measures as the director deems necessary to reduce erosion and related sedimentation to minimal levels. The full costs of said measures and the related inspections shall be borne by the property owner.

2.

Five percent of projects that have received a final inspection and been found complete by the director shall be spot checked by the director each year to confirm groundcover condition and the proper operation of other erosion control measures. The director, in cooperation with the Napa County Resource Conservation District (RCD) and other county departments and agencies, will develop a remedial program to address any deficiencies that may be identified as the result of these spot checks. The property owner shall implement this program, which may include re-seeding all or some portions of the site or changing agricultural or management practices. The property owner shall pay all costs associated with these spotchecks.

F.

Right of Entry. With the property owner's consent, with a warrant, or in an emergency, the property owner shall give the director full and complete access to and throughout the project area so as to allow:

Inspection of the erosion control and any remedial measures installed there to insure that they are functioning properly;

2.

The making of necessary repairs or corrections to alleviate an erosion control problem or potential erosion control problem; or

3.

The performance of needed maintenance.

Chapter 18.112 - ROAD SETBACKS

18.112.010 - Establishment—Purpose.

The board of supervisors declares that the county, through the planning commission and the board of supervisors, is engaged in developing and updating the master plan of streets and highways within the county for the purpose of assuring ample transportation facilities for the present and future; that the magnitude of the undertaking precludes precise plans being completed in their entirety in time to fully guide all development occurring within the county; that the surveys, hearings, map preparation and requirements of the law governing such matters necessitate such detailed plans being developed progressively; that to conserve the public interest and to assure economies and public safety and welfare it is imperative that necessary rights-of-way for streets and highways within the county be protected against encroachment by permanent physical improvements, the existence of which would make unnecessarily difficult or make impractical the retention or creation of thoroughfares adequate in alignment, dimensions and vision clearance to serve the public needs, safety and welfare; and that to deal effectively with the practical problem thus presented, certain minimum road setbacks are hereby established on a county-wide basis.

Electrical distribution lines on the project site shall be underground. This provision may be waived by the decisionmaking body if the undergrounding is determined to be an undue burden.

3.

Concentrated reflections or glare shall not be directed at occupied structures, recreation areas, roads, highways or airport flight landing or takeoff areas. A detailed analysis of potential glare effects may be required at the time of application, and the applicant may be required to minimize glare effects by installing vegetative screens or berms, and/or by adjusting solar collector position or operation to minimize glare.

D.

Notwithstanding any other processing requirements to the contrary, commercial renewable energy facilities may be collocated on a developed property within those zoning districts permitting such facilities without obtaining a new use permit, provided that either:

1.

The facility is consistent with the terms of the use permit or site plan approval previously granted for the developed property; or

2.

The use permit or site plan approval is being modified to incorporate the facility.
