(Ord. No. 2010-265, § 3, 1-27-2010)
17.48.030 - Installation of improvements. ¶
Subdivision improvements required as conditions of approval of a tentative map in compliance with this chapter (See Section 17.46.010(B)) shall be installed as provided by this section.
A.
Timing of Improvements. Required improvements shall be constructed or otherwise installed only after the approval of improvement plans as provided by Section 17.48.020, and before the approval of a parcel or final map in compliance with Sections 17.42.140 or 17.42.230, except where:
1.
Improvements are deferred in compliance with Section 17.48.040; or
2.
Improvements are required as conditions on the approval of a subdivision of four or fewer lots, in which case construction of the improvements shall be required:
a.
Only when a permit for development of an affected parcel is issued by the department, or
b.
At the time the construction of the improvements is required in compliance with an agreement between the subdivider and the city, as set forth in Section 17.48.040, or
c.
At the time set forth in a condition of approval, when the review authority finds that fulfillment of the construction requirements by that time is necessary for public health and safety, or because the required construction is a necessary prerequisite to the orderly development of the surrounding area.
B.
Inspection of Improvements. The construction and installation of required subdivision improvements shall occur as follows.
1.
Supervision. Before starting any work, the contractor engaged by the subdivider shall designate in writing an authorized representative who shall have the authority to represent and act for the contractor in contacts with the city. The designated representative shall be present at the work site at all times while work is in progress. At times when work is suspended, arrangements acceptable to the city engineer shall be made for any emergency work that may be required.
2.
Inspection Procedures.
a.
Inspections Required. The city engineer shall make any inspections as he or she deems necessary to ensure that all construction complies with the approved improvement plans. Where required by the city engineer, the developer shall enter into an agreement with the city to pay the full cost of any contract inspection services determined to be necessary by the city engineer.
b.
Access to Site and Materials. The city engineer shall have access to the work site at all times during construction, and shall be furnished with every reasonable facility for verifying that the materials and workmanship are in accordance with the approved improvement plans.
c.
Authority for Approval. The work done and all materials furnished shall be subject to the inspection and approval of the city engineer. The inspection of the work or materials shall not relieve the contractor of any obligations to fulfill the work as prescribed.
d.
Improper Work or Materials. Work or materials not meeting the requirements of the approved plans and specifications may be rejected, regardless of whether the work or materials were previously inspected by the city engineer. In the event that the city engineer determines that subdivision improvements are not being constructed as required by the approved plans and specifications, he or she shall order the work stopped and shall inform the contractor of the reasons for stopping work and the corrective measures necessary to resume work. Any work done after issuance of a stop work order shall be a violation of this title.
3.
Notification. The subdivider shall notify the city engineer upon the completion of each stage of construction as outlined in this chapter, and shall not proceed with further construction until authorized by the city engineer.
(Ord. No. 2010-265, § 3, 1-27-2010)

There shall be no partial acceptance of any improvements.
