Portola Valley Municipal Code Ch. 17.52 Improvements

The subdivider shall improve, or agree in writing to improve, all public or private streets, highways, pathways, trails and easements, and to install other improvements required by this title as are necessary for the general use of lot owners in the subdivision, local neighborhood traffic, and drainage needs.

(Ord. 1967-71 § 1 (7660.01), 1967)

The subdivider shall submit a complete set of plans, profiles, cross sections, and specifications for improvements, on acceptable reproducible material, to the town engineer for check and approval. If approved, the town engineer shall certify his approval on the face of such tracings and/or other reproducible material, and the subdivider shall, at his own expense, furnish the town six complete sets of prints. One set shall be kept as a part of the permanent records of the town. Tracings and other reproducible material shall be returned to the subdivider.

(Ord. 1967-71 § 1 (7660.02), 1967)

No improvement work shall be commenced until improvement plans and specifications have been approved by the council on recommendation of the town engineer or other representatives of the town authorized by the council. Improvements shall be installed in accordance with the approved plans and specifications to permanent line and grade to the satisfaction of the town engineer. All work shall be done under the supervision of the town engineer and shall be subject to such inspection as he or she deems necessary to protect the interests of the town. In the case of trails, all work and improvements shall be supervised by the trails coordinator designated by the town and shall be subject to such inspection as he or she deems necessary to protect the interests of the town. Trails and paths shall be constructed prior to acceptance of roads and utilities. In no case shall improvements be less substantial than required by the standard specifications of the town, adopted by the council and in effect at the time the tentative map was approved by the planning commission. All improvements shall conform with the standards of this title and all grading shall conform to the requirements of the site development ordinance.

(Ord. 1997-303 § 8, 1997: Ord. 1979-168 § 6, 1979: Ord. 1967-71 § 1 (7660.03), 1967)

The town engineer, his authorized representative or other representative of the town authorized by the council, shall have the right to enter upon the site of the improvements for the purpose of inspecting the same and shall be furnished with samples of materials as he may require for making tests to determine the acceptability of such materials. Prior to beginning work, the subdivider shall deposit with the town the amount equal to the estimated actual cost for the inspection of the work and the cost of checking of materials for the improvements during the entire period of construction. If all improvements are not complete when the final map is presented to the council, the subdivider shall give evidence that he has deposited with the town a sum in the amount estimated by the town engineer as being sufficient to cover the costs of such inspection, tests and other engineering costs. If the amount so deposited exceeds the actual cost to the town, the subdivider shall be reimbursed for the balance remaining. If the actual cost exceeds the deposited amount, the town engineer shall stop all construction until the subdivider shall present a receipt for a deposit with the town of an additional sum as estimated by the town engineer.

(Ord. 1967-71 § 1 (7660.04), 1967)

The minimum improvements which the subdivider shall make, or agree to make, at the cost of the subdivider, prior to acceptance and approval of the final map by the town, shall be:

A. Grading, curbs, and gutters or berms where required by the town engineer, paving, drainage and drainage structures necessary for the proper use and drainage of streets, highways and pathways and for the drainage of public property and prevention or control of erosion of public properties for the public safety;

B. Essential grading and drainage, taking into consideration the drainage pattern of adjacent improved or unimproved property and treating upstream areas as though fully improved;

C. Street name signs, traffic warning signs, required painted traffic lines and crosswalks;

D. Pedestrian paths and trails as required;

E. Fire hydrants with gated or comparable connections and appurtenances, in proper locations, and in sufficient numbers to provide adequate fire protection; such facilities shall be in conformance with the standards of the Woodside fire protection district;

F. A water system with mains of sufficient size and having a sufficient number of outlets to furnish an adequate water supply for all lots in the subdivision and to provide adequate fire protection;

G. Sanitary sewer facilities and connections for each lot if required in the approval of the tentative map;

H. Street plantings;

I. All telephone, telegraph, light and power wires and cables, and all communication wires and cables shall be placed underground, except as noted in Section 17.48.010.

(Ord. 1967-71 § 1 (7660.2), 1967)

Provisions for service connections from utility lines and sanitary sewers shall normally be made available for each lot in such manner as will obviate the necessity for disturbing the street pavement, paved curb and gutter and culverts, when service connections are made.

(Ord. 1967-71 § 1 (7660.4), 1967)

The subdivider shall guarantee the work in providing the above facilities and shall make or agree to make necessary repairs or modifications for damage resulting from storms, erosion or landslide and to correct errors in design or construction for a period of a minimum of one year after the date of completion described in Section 17.52.080.

(Ord. 1967-71 § 1 (7660.6), 1967)

A complete improvement plan "as-built" shall be filed with the town engineer upon completion of the required improvements. The "as-built" plans shall be in the form of original or duplicate tracings on cloth or equivalent materials at a scale acceptable to the town engineer, on twenty-four-inch by thirty-six-inch sheets with two-inch left margin. Upon receipt and acceptance of the "as-built" plans, the town engineer shall recommend formal acceptance by the council when he is satisfied that the improvements have been installed in complete conformance with this title and the standard specifications of the town.

(Ord. 1967-71 § 1 (7660.8), 1967)
