C. In case of conflict between the codes referenced in this chapter and other development codes adopted by the City, the code that, in the opinion of the Community Development Director, is more restrictive or more protective of public safety shall prevail. (Ord. 2453 § 1, 2007).

The Building Official may require the collection of an investigation fee, in addition to the permit fee, in an amount equal to the permit fee required by this code.

15.05.300 Public right-of-way – Private encroachment.

It shall be unlawful for any person, firm, or corporation to erect, construct, or maintain any building, fence, structure, or thing encroaching upon, under, or over any land that is part of the public right-of-way, except as permitted under Chapter 32 of the IBC or subsections A and B of this section.

Neither the City nor the franchise agencies are required to replace or restore any encroachments that are damaged or removed; however, the City or franchise holder must repair, to the satisfaction of the City Engineer, any damaged area within the public right-of-way or easement.

C. The planting or maintenance of trees and other plants within the public right-of-way does not require a permit; provided, that such planting or maintenance conforms with all other applicable codes and standards. Trees and other plants with invasive roots shall not be allowed on or within 10 feet of the public rights-of-way and public easements where the invasive roots of such trees or plants may damage public facilities. The Community and Economic Development Department may compile a list of acceptable trees and other plants that have noninvasive roots and that are generally compatible with the function of the public right-of-way or easement. Where plants with invasive roots damage the storm lines, sanitary sewer lines, water lines, or any other underground facility, the owner of such plantings is required to remove them, and is held liable for all repair and replacement costs for City-owned facilities.

Project improvement valuation will accumulate over a consecutive three-year period.

Exceptions:

a. When the nearest point of connection to the distribution system is an overhead facility on a utility pole and is greater than 100 feet away from the single-family dwelling, the property will be exempt from requiring undergrounding of power and other wireline services.
