17.28.010 General.

A. Standards.

1. The subdivider shall design and construct all required improvements on-site and off-site in accordance with standard engineering specifications and standard details and other approved standards as provided by this chapter and as adopted by the city. Subject to the Subdivision Map Act, the city engineer may authorize an exception to the construction standards in this chapter.

2. A decision or interpretation of the city engineer regarding the specifications, details or design of improvements is final.

3. No final map may be presented to the council or parcel map to the city engineer for approval until the subdivider either completes the required improvements or enters into an improvement agreement with the city agreeing to do the work.

B. Energy Conservation.

1. The design of a subdivision for which a tentative map is required, excluding a conversion, shall provide to the extent feasible, for future passive or natural heating or cooling opportunities in the subdivision. Examples of such energy conservation opportunities in subdivision design include design of lot size and configuration to permit orientation of a structure in an east-west alignment for southern exposure or to take advantage of shade or prevailing breezes. (Government Code Section 66473.1.)

2. “Feasible” means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social and technological factors.

3. Compliance with this provision shall not result in reducing allowable densities or the percentage of a lot which may be occupied by a building or structure. [Ord. 962 § 2 (Exh. A), 1989.]

17.28.020 Improvements required.

A. General.

1. All improvements required as tentative map conditions of approval or by city ordinance or resolution, together with the required improvements set forth below, are required of all subdivisions.

2. The requirements for construction of on-site and off-site improvements for a subdivision of four or fewer parcels shall be noted on the parcel or final map, waiver of parcel map, or the subdivision improvement agreement recorded before or concurrently with the map.

B. Frontage Improvements. The frontage of each lot shall be improved to its ultimate adopted geometric section, including but not limited to street structural section, curbs, sidewalks, driveway approaches and transitions as determined by the city engineer.

C. Storm Drainage. Stormwater runoff from the subdivision shall be collected and conveyed by an approved storm drain system. The storm drain system shall be designed for ultimate development of the watershed. The storm drain system shall provide for the protection of abutting and off-site properties that would be adversely affected by any increase in runoff attributed to the development. Off-site storm drain improvements may be required to satisfy this requirement. (Government Code Section 66411.)

D. Sanitary Sewers. Each unit or lot within the subdivision shall be served by an approved sanitary sewer system with a minimum eight-inch diameter main line.

E. Water Supply. Each unit or lot within the subdivision shall be served by an approved domestic water system.

F. Utilities. Each unit or lot within the subdivision shall be served by gas (if required), electric, telephone and cablevision facilities. (Government Code Sections 66473.2, 66473.3.)


G. Underground Utilities.

1. All existing and proposed utilities within the subdivision and along frontage streets shall be placed underground except those facilities exempted by the Public Utilities Commission regulations. Undergrounding is required for overhead lines on either side of peripheral streets.

2. The subdivider is responsible for complying with the requirements of this chapter and shall make the necessary arrangements with each utility company for installation of the facilities.

3. The planning commission may grant an exception to the undergrounding requirements as provided in this subsection if topographical soil or other conditions make underground installation of the facilities unreasonable.

H. Access. Every lot or parcel created shall have access to a public or private street improved to city standards. Private streets are not normally permitted. The subdivider shall submit a development plan showing the alignment, width, grade, and material specifications of a proposed private street, the topography and means of access to each lot, and the drainage and sewerage of the lots served by the private street. Construction of the private street, as approved by the city engineer, shall be completed before the completion of the construction or occupancy of the lots. The subdivider shall demonstrate and provide a feasible method for the maintenance of private streets.

Reserve strips, or nonaccess at the end of streets or at the boundaries of subdivision, shall be dedicated unconditionally to the city when required by the city.

I. Other Improvements – Monuments.

1. Other improvements such as street lights, fire hydrants, signs, street trees and shrubs, monuments, and smoke detectors, or fees in lieu of any of the foregoing, are required as determined by the city engineer in accord with this title and city standards and specifications.

2. At the time of making the survey for the final or parcel map, the engineer or surveyor shall set sufficient durable monuments to conform with (a) the standards described in Business and Professions Code Section 8771, and (b) the city standards, so that another engineer or surveyor may easily retrace the survey.

3. Interior monuments need not be set at the time the map is recorded if the engineer or surveyor certifies on the map that the monuments will be set by a specified date and if the subdivider provides security to guarantee the cost.

4. Within five days after the final setting of all monuments, the engineer or surveyor shall give written notice to the subdivider and to the city engineer. (Government Code Sections 66495 through 66498.)

J. Off-Site Improvements. If the subdivider is required to construct off-site improvements on land in which neither the subdivider nor the city has sufficient title or interest to allow construction: (Government Code Section 66462.5.)

1. The city may, before approving the parcel or final map, require the subdivider to enter into an agreement to complete the off-site improvements at the time the city acquires title of an interest in the land. The subdivider shall pay the cost of acquiring off-site land or an interest in the land required to construct the off-site improvements; or

2. The city shall, within 120 days of recording the final map, acquire by negotiation or commence condemnation of the land. If the city fails to meet the 120-day time limit, the condition for the construction is waived. [Ord. 962 § 2 (Exh. A), 1989.]

17.28.030 Reimbursement agreements.

If the improvements required to be installed by the subdivider under PMC 17.28.020 contain supplemental size, capacity, number or length for the benefit of property not within the subdivision and are to be dedicated to the public, the subdivider may request that the city enter into a reimbursement agreement. A subdivider requesting a reimbursement agreement shall submit an application to the city in accordance with procedures set forth in Chapter 12.44 PMC. The city may not approve a reimbursement agreement after the date construction begins on the improvements. (Government Code Sections 66485 through 66487, 66475.4.) [Ord. 962 § 2 (Exh. A), 1989.]

17.28.040 Deferred improvement agreements.

A. Minor Subdivisions. If the city engineer considers it necessary, the frontage improvements along existing peripheral streets of a minor subdivision may be deferred. When improvements are deferred, the owner of the real property shall enter into an agreement with the city in a form acceptable to the city engineer and city attorney, for the installation of all frontage improvements at a time in the future as specified by the city. The agreement shall provide that: (Government Code Section 66411.1.)

1. The owner shall begin construction of improvements within 90 days of the receipt of the notice to proceed from the city, or as mutually agreed upon in writing;

2. In the event of a default by the owner, the city is authorized to cause construction to be done and charge the entire cost and expense to the owner, including interest from the date of notice of the cost and expense until paid;

3. The agreement shall be recorded with the county recorder at the expense of the owner and shall constitute notice to all successors and assigns of title to the real property of the obligations set forth therein, and shall also constitute a lien in such amount necessary to fully reimburse the city, including interest as provided above, subject to foreclosure in the event of a default in payment. The obligations under the agreement shall run with the property and constitute a lien against it.

4. In the event of litigation occasioned by default of the owner, the owner agrees to pay all costs involved, including reasonable attorneys’ fees. Those costs shall become a part of the lien against the real property.

The construction of deferred improvements shall conform to this title and all applicable provisions of this code in effect at the time of construction.

B. Remainders. For a designated remainder parcel, the fulfillment of construction requirements for improvements is not required until the city is ready to issue a permit or other grant of approval for development of the remainder parcel or until the construction of the improvements is required under an agreement between the subdivider and the city. In the absence of an agreement, the city may require fulfillment of the construction requirements within a reasonable time following approval of the final map and before the issuance of a permit or other grant of approval for the development of a remainder parcel upon a finding by the city that fulfillment of the construction requirements is necessary for reasons of: (Government Code Section 66424.6.)

1. The public health and safety; or

2. The required construction is a necessary prerequisite to the orderly development of the surrounding area.

If a designated remainder is subsequently sold, the subdivider of owner must obtain a certificate of compliance or conditional certificate of compliance. [Ord. 962 § 2 (Exh. A), 1989.]

2. The subdivider shall complete improvements before final building inspection or the issuance of an occupancy permit for any unit in the subdivision.

3. If the subdivider fails to complete the improvements within the specified time, the city may by resolution of the city council and at its option cause the uncompleted improvements to be completed and the parties executing the performance security shall be firmly bound for the payment of all necessary costs.

B. Minor Subdivisions.

1. The subdivider shall complete improvements in a minor subdivision before final building inspection or the issuance of an occupancy permit for any unit in the subdivision.

2. The completion of improvements for divisions of four or fewer parcels is not required until a permit or other grant of approval for the development of a lot within the subdivision is applied for. However, the city may require completion of the improvements by a specified date when it finds that the completion of the improvements is necessary for public health or safety or for the orderly development of the surrounding area. The city engineer may make this finding. The specified date, when required, shall be stated in the subdivision improvement agreement. (Government Code Section 66411.1.)

C. Extensions.

1. The city council in the case of a major subdivision and the city engineer in the case of a minor subdivision may extend the completion date upon written request by the subdivider and the submittal of adequate evidence to justify the extension. The request shall be made at least 30 days before expiration of the subdivision improvement agreement.

2. The subdivider shall enter into a subdivision improvement agreement extension with the city. For a major subdivision, the agreement shall be prepared and signed by the city engineer, approved as to form by the city attorney, executed by the subdivider and surety and transmitted to the city council for its consideration. If approved by the city council, the mayor shall execute the agreement on behalf of the city. For minor subdivision, the same procedure shall be followed, except that the agreement shall be considered by the city engineer, and if approved, executed by the city engineer on behalf of the city.

3. In passing upon a request for a subdivision improvement agreement extension, the city may require the following:

a. Revision of improvement plans to provide for current design and construction standards when required by the city engineer;

b. Revised improvement construction estimates to reflect current improvement costs as approved by the city engineer;

c. Increase of improvement securities in accordance with revised construction estimates;
