The determination of the city council as to the necessity for construction shall be conclusive.

B. Before the start of construction of a new residence on any lot in the town, the director of public works or the director's designee shall determine the adequacy of any existing system of gutters, curbs or culverts along the street in front of the lot. The director of public works or the director's designee may require as a condition of the improvement of the lot, that the owner or developer (1) install curbs, gutters or culverts sufficient to complete the line of any curbs, gutters or improvements on adjoining real property, or to protect the real property in question, or to satisfy any requirements imposed pursuant to the town's current NPDES permit or green infrastructure plan approved by the city council, or (2) complete or install any related facilities (including, but not limited to, water pipes, water valves, fire hydrants, sewer clean-outs and flap gates, and storm drain inlets) usually required along the street frontage or identified as an opportunity for green infrastructure in the green infrastructure plan approved by the city council.

C. The director of public works or the director's designee shall notify in writing any property owner required to construct or repair frontage improvements under the provisions of subsection A or B of this section. Such notice shall be mailed by U.S. mail to the address of the owner of the property as listed in the records of the San Mateo County Assessor. If there is no response within two weeks from the date of mailing, a second notice shall be mailed by U.S. mail to the same address and to the address (if different) to which water bills for such property are sent, certified mail, return receipt requested.

D. In the event that a property owner fails to respond to the second notice within thirty days from the date of mailing (or such shorter time as set forth in subsection E of this section) or fails to have the required construction, repair or replacement completed by the deadline set forth in the notice(s) (which shall take into account the nature of the work needed, the urgency of the work, and the availability of workers to perform the work), the director of public works or the director's designee shall cause the construction or repair to be done. In such event, the cost thereof, including, but not limited to, all permit and any other administrative fees that would be been charged to the property owner or the owner's representative had the owner caused the construction or repair to be done, shall be assessed against the owner and referred to collection or recoverable in a civil action in any court of competent jurisdiction, and the judgment of the court shall include costs and a reasonable attorney's fee to be fixed by the court.

E. The time periods in subsections C and D of this section may be shortened as necessary by the director of public works or the director's designee if a hazardous condition exists which requires prompt or immediate abatement in order to protect the public health, safety or welfare. Any shortened time period shall be set forth in the notice(s).

F. Except as temporarily necessary to complete construction, repair or replacement required under this section, every owner or occupant of real property in the town shall keep any culvert or gutter located on such property clean and free at all times from all obstructions to the free passage of water.

G. 1. No person shall paint or cause to be affixed address numbers or related symbol, legend or marking upon the streets, gutters or curbs located within the town without the prior written approval of the owner of the property (a) served by the address number or related symbol, legend or marking so painted or affixed, or (b) adjoining the streets, gutters or curbs so painted or marked. Such written approval shall not create nor imply an obligation to pay for work performed unless such obligation is specifically set forth therein, in which case the amount to be paid or donated for the service shall be specifically listed on the written approval.

  1. Persons engaged in the painting of address numbers, symbols, legends or markings for profit or for charity shall, before advertising, soliciting or performing such work, comply with the provisions of all resolutions and ordinances of the town pertaining to such work.

  2. Painted address numbers, symbols, legends or markings shall be painted with black paint, four inches in height, stenciled and centered on a reflective, white painted, rectangular background not to exceed fifteen inches in length by six inches in height.

A. Any public street, or portion thereof, which has been constructed, reconstructed, or paved by town staff, under contract with the town or under permit, shall not be excavated or cut into if it has been overlaid with at least one inch of asphaltic concrete at any time during the five years prior to the request to excavate or cut into or has been overlaid with a slurry seal at any time during the two years prior to the request to excavate or cut into.

B. The city engineer may grant exemptions to the foregoing prohibition in order to facilitate development on adjacent properties, or to provide emergency repairs to subsurface facilities. When granting an exemption, conditions to mitigate the damage to the roadways and to ensure safe and structurally sound excavation shall be imposed by the town which may include surface grinding, sub-base repairs, asphaltic concrete overlays or slurry seals on full width and full block increments. The town reserves the right to specify additional conditions to ensure that the appearance of the work when completed shall not degrade from the appearance of the street on which the work is conducted and the surrounding area. All costs, not limited to plan review, construction inspection, material testing, bonding, and other town expenses incurred in connection therewith, shall be the responsibility of the party receiving the exemption. Receipt of the exemption shall not relieve the recipient from complying with the permit requirements of this chapter.

C. Should excavation work be planned within a public roadway section not covered by subsection A. above, the permittee shall be required to pay the Town a slurry seal in-lieu fee to cover the cost of a full roadway width slurry seal on that portion of the street affected by the permittee's excavation. This fee shall be updated yearly, approved by the city council and included in the schedule of fees and charges as included in the town's annual budget.
