Exceptions & meaning →

17.20.080 - Improvements required.

A. The subdivider, person, firm, corporation, partnership or association shall improve, or agree to improve, as provided in this title, all streets, highways, alleys, ways or easements in the subdivision as a condition precedent to acceptance thereof and approval of the final map. All pipelines, electrical conduit and other underground facilities shall be installed prior to street paving. All utilities, curbs, gutters and pavement shall be installed on such existing major and secondary streets and other streets as may be designated by the city council within ninety days after the issuance of the initial permit from the department of development services for all or a part of a subdivision. Such improvements shall be installed at lines and grades and in accordance with the standard specifications approved by the city council. Failure to comply with any of the above requirements shall be a ground for the city council or the city administrator to order cessation of all building construction. Final approval, excepting for a temporary approval of no more than three models for tract office and subdivision sales purposes, will not be granted for any building until all improvements have been installed and accepted by the city.

B. Improvements shall include:

  1. Grading, drainage and drainage structures necessary to proper use and to the public safety;

  2. Curbs and gutters;

  3. Sidewalks of a width and quality as the planning commission may consider suitable for the local neighborhood use;

  4. Pavement of a width and quality suitable for local neighborhood traffic;

  5. Adequate domestic water supply and the transfer and conveyance to the city of all right, title and interest in and to the overlying water rights of the property. Where the land has traditionally received irrigation water service, the owner or developer shall transfer to the city clear and unencumbered title to shares of stock in the company traditionally serving the land. The shares to be transferred shall be the number which by custom and common usage are required for the proper irrigation of the land. The intent and purpose of requiring the transfer of water stock where available are so that water for use in the city domestic water system will be available as the land develops. It is recognized that Lytle Creek Water and Improvement Company and Citizens Land and Water Company have been sold to the West San Bernardino County Water District and that no stock of these companies remains in existence. Due to the absence of any stock in these companies this paragraph shall not apply to any land traditionally served irrigation water by either of these two companies or by the city;

  6. Sanitary sewer facilities and connections for each lot in such manner as will obviate the necessity for disturbing the street pavement, gutter, curb and sidewalk when service connections are made;

  7. Services from public utilities where provided;

  8. All trees shall be planted as required by the department of development services in locations selected by said department and the reasonable cost of the trees and planting thereof shall be paid by the subdivider;

  9. Street lights;

  10. Permanent subdivision survey monuments;

  11. In addition to the aforesaid minimum improvements, the planning commission shall recommend and the city council shall require such additional improvements and facilities or such modifications in the standards of minimum improvements as special conditions may cause the planning commission to make a special finding of need;

  12. All water lines are to be laid pursuant to plans and specifications of the city;

  13. Utility lines, including but not limited to electric, communications, street lighting and cable television, shall be required to be placed underground. All existing utility lines, including, but not limited to, electric, communications, street lighting and cable television located on, across or adjacent to the property being developed shall be placed underground. The subdivider is responsible for complying with the requirements of this section, and he/she shall make the necessary arrangements with the utility companies for the installation of such facilities. For the purpose of this section, appurtenances and associated equipment such as, but not limited to, surface-mounted transformers, pedestal-mounted terminal boxes and meter cabinets, and concealed ducts in an underground system may be placed above ground.

C. If such improvement work is not completed satisfactorily before the final map is approved, the owner or owners of the subdivision shall, prior to approval of the final map, enter as contractor into an agreement with the city council whereby, in consideration of the acceptance by the city council of the streets and easements offered for dedication, to complete the work within the time specified in the agreement. To assure the city that this work will be completed, a bond shall be furnished guaranteeing the faithful performance of the work in the sum equal to the cost as estimated by the city engineer. Ninety percent of this bond may be furnished by a qualified surety company, except in cases where a cash deposit is required by the city council. Ten percent of the bond amount must be cash or a letter of credit payable upon demand of the city. This money may be used as directed by the city administrator or a person designated by him/her to pay the cost of maintaining barricades, correcting street hazards or repairing any street irrigation line or other utility causing a hazard, nuisance or inconvenience to the public.

D. Prior to final approval of a subdivision map by the city council, the owner shall submit a construction schedule showing the beginning date of construction of each item to be built in the public right-of-way, together with the estimated time required for completion. Any unauthorized delay or variation from this schedule shall be cause for the city council to authorize using the cash bond deposited by the owner to correct any condition causing public inconvenience.
