(A) Frontage improvements. The frontage of each lot shall be improved to its ultimate adopted geometric section, including street structural sections, curbs, sidewalks, driveway approaches and transitions.
(B) 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 and shall be capable of collecting and conveying runoff generated by a 100-year flood. The storm drain system shall provide for the protection of abutting and off-site properties that could be adversely affected by any increase in runoff attributed to the development. Off-site storm drain improvements may be required to satisfy this requirement. Internal drainage facilities shall be designed and constructed in conformance with county standards for subdivision improvements.
(C) Sanitary sewers. Each unit or lot within the subdivision shall be served by an approved sanitary sewer system or on-site sewage disposal system, in accordance with the provisions of Chapter 15.07 of this code.
(D) Water supply. Each unit or lot within the subdivision shall be served by an approved domestic water system, in accordance with the provisions of Chapter 15.05 of this code and state law.
(E) Utilities. Each unit or lot within the subdivision shall be served by gas, electric, telephone and cablevision facilities where available.
(F) Underground utilities.
(1) All proposed utilities within the subdivision and along peripheral streets shall be placed underground except those facilities exempted by Public Utilities Commission regulations. Undergrounding of existing utilities shall be required for overhead lines on the development side of peripheral streets. Power transmission of voltage greater than 21 KV shall be exempt from this section.
(2) The developer may request that the undergrounding requirement along peripheral streets be waived by the Planning Commission. The Planning Commission may, at its discretion, accept a fee in lieu of the undergrounding. The amount of the fee shall be determined by the County Engineer and shall be based upon the reasonable estimated cost of that portion of a future undergrounding project attributable to the subdivision. The requirement for undergrounding shall be a condition of approval of the tentative map, except as provided below.
(3) Undergrounding requirements may be waived or modified by the Planning Commission only upon finding:
(a) The subdivision is within an area where existing utilities have not been underground;
(b) Undergrounding of utilities is impractical due to physical constraints, or the surrounding neighborhood is absent of similar improvements; and
(c) Overhead utilities will have no significant visual impact.
(4) If the undergrounding requirements are waived as provided in division (F)(3) above, the in-lieu fee as established by the County Engineer may be made a condition of approval of the tentative map.
(5) In-lieu fees shall be deposited in a special undergrounding account to be used as approved by the Board of Supervisors for future undergrounding of utilities throughout the county.
(6) The provisions of this division are in addition to, and not in substitution for or limitation of, the provisions of Chapter 15.03 of this code.
(G) Fencing. Each unit or lot within the subdivision that is adjacent to property containing a public facility shall have an approved fence adequate to prevent unauthorized access between the properties.
(H) Other improvements. Other improvements including, but not limited to, grading, street lights, fire hydrants, signs, street lines and markings, street trees and shrubs, landscaping, monuments, bicycle facilities and fences, or fees in lieu of any of the foregoing, shall also be required as determined by the County Engineer in accordance with this code, the general plan and county standards and specifications.
(I) Off-site improvements. If as a condition of a tentative map a subdivider is required to construct off-site improvements on land in which neither the subdivider nor the county has sufficient title or interest to allow construction at the time the map is recorded with the county, the county shall, within 120 days of recording the final map, acquire by negotiation or commence condemnation of the land in conformity with Cal. Gov’t Code § 66462.5. If the county fails to meet the 120-day time limit, the condition for the construction shall be waived. Prior to approval of the final map, the county may require the subdivider to enter into an agreement to complete the off-site improvements at the time the county acquires title or 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.
