19.166.010 - Purpose

This Chapter establishes regulations for dedications and improvements.

19.166.020 - Dedication Requirements

The subdivider, as a condition of approval of a Tentative Map, shall dedicate, or make an irrevocable offer of dedication, of all parcels of land within the subdivision that are needed for streets and alleys, including access rights and abutter's rights, drainage, public open space, trails, scenic easements, public utility easements and other public easements, in accordance with the Subdivision Map Act, the goals and policies of the adopted General Plan and adopted standards. All dedications to the City for public purposes

shall be made in fee title unless otherwise determined by the City Council; at the City's discretion, a grant of an easement may be accepted for open space, scenic easements, trails, parks, public utility easements or other interests as may be determined by the City Council. All dedications and grants in fee of easements shall be free of liens and encumbrances except those which the City finds would not conflict with the intended use. The City may accept an irrevocable offer of dedication in place of dedication when appropriate.

A.

Waiver of Direct Access Rights. Dedications or offers of dedications of streets may include a waiver of direct access rights to any such street from any property shown on the Final Map as abutting the street. If the dedication is accepted, any provision for waiver of direct access rights shall become effective in accordance with its provisions.

B.

Reservations. Subject to and in accordance with applicable provisions of law, including the Subdivision Map Act, the subdivider, as a condition of approval of a Tentative Map, may be required to dedicate areas of real property for parks, recreational facilities, fire stations, libraries or other public uses.

C.

School Site Reservations. Subject to and in accordance with applicable provisions of law, including the Subdivision Map Act, the subdivider, as a condition of approval of a Tentative Map, may be required to dedicate real property for the construction of an elementary school to assure the residents of the subdivision adequate public school service.

19.166.030 - Improvement Regulations

A.

The following are improvement requirements for Parcel Maps for detached single-family projects:

1.

Parcel Maps which subdivide lots for the development of those lots for single-family residences shall provide the following:

a.

One point of paved access to an existing paved road and interior street paving shall be required as a condition of Final Map approval for Parcel Map projects when any of the resulting parcels are less than 2.5 gross acres in size.

b.

Paved access to an existing paved road and interior street paving shall not be required as a condition of Final Map approval for Parcel Map projects when all of the resulting parcels are equal to or greater than 2.5 gross acres in size, or the Planning Commission finds that given the particular location and circumstances

of the project such paving would be unreasonable based on the following standards: the primary public access road is unpaved for a distance greater than 1,000 feet; or such access road is farther than 1,000 feet from a paved public road, and such public access road is not identified on the City's Capital Improvement Program for paving. In all such cases the developer shall comply with (i), (ii), (iii) or (iv) below, as approved by the City Engineer:

i.

An in-lieu fee as approved by the City Engineer is paid to the City prior to map recordation to cover the particular development's fair share obligation for paving the access road; or

ii.

The owner of the property being developed executes an agreement with the City not to protest the formation of an assessment district created for the purpose of constructing paved roads; or

iii.

The property being developed is within the boundaries of an assessment district created for the purpose of paving and maintaining the local roads, which will provide direct access to the site being developed; or

iv.

The improvements have been deferred in accordance with Subsection 19.166.030.D.

2.

Parcel Maps which subdivide the land into parcels larger than the range of minimum lot sizes permitted in the land use district shall be required to install improvements as a condition of Final Map approval, except where the improvements have been deferred in accordance with Section 19.166.030.D.

B.

The following are improvement requirements for the following parcel maps. Street improvements for commercial, industrial and/or multi-family developments, or Parcel Maps which are used as a financing vehicle for new development or described in paragraph 2 above, may be deferred and/or phased by the approval authority on a case-by-case basis subject to the criteria below. Improvements for such projects shall be required when a building permit is issued unless a deferral agreement is approved and recorded against the property which guarantees performance at the time determined necessary by the City Engineer.

C.

Parcel Maps which are used as a financing vehicle shall be defined for purposes of this Section as a Parcel Map which is processed in conjunction with or subsequent to another type of land use approval (e.g., subdivision, site plan review, Conditional Use Permit, Specific Plan) under which improvements are required to be installed.

D.

The approval authority may grant approval for a deferral of improvements or a partial deferral of improvements with good cause. The approving authority shall direct that a deferral agreement be executed in such cases. The approval authority may grant approval of deferral of improvements only when a finding can be made that the parcel or subject property is in reasonable proximity to existing improvements and infrastructure and that the necessary improvements to serve development of the property can or will be feasibly provided.

E.

Improvement Agreement. Prior to submitting a Final Map for approval, the subdivider shall execute an improvement agreement, in a form approved by the City Engineer and City Attorney, specifying the time by which the required improvements will be completed. The improvement agreement shall be reviewed by the City Council and, if approved, executed by the City Manager. The improvement agreement shall be secured as provided for in Subsection 19.166.030.G (Improvement Security) of this Chapter.

F.

Improvement Agreement; Time Extensions. The completion date specified in the improvement agreement, or as specified in paragraph (E) above, may be extended by the City Council for subdivisions of five or more parcels and by the City Engineer for subdivisions of four or fewer parcels upon a written request by the subdivider. The request for said time extensions, along with the appropriate application, materials and fees, shall be submitted at least 30 days prior to the expiration of the improvement agreement or the time specified in paragraph (E) above.

A bond or bonds by one or more duly authorized corporate sureties.

2.

A deposit, either with the local agency or a responsible escrow agent or trust company, of money or negotiable bonds of the kind approved for securing deposits of public monies.

3.

An irrevocable instrument of credit from one or more financial institutions subject to regulation by the state or federal government pledging that the funds necessary to carry out the agreements are on deposit, guaranteed for payment, and constitute a trust fund which is not subject to levy or attachment by any creditor of the depositor until released by the City.
