IMPROVEMENTS

Sections:

17.30.010 Improvement standards and approval.

In addition to other requirements, all improvements shall conform to the requirements of this chapter and any other improvement standards or specifications adopted by the city, and shall be installed in accordance with the following procedures:

A. Improvement work shall not be commenced until plans have been checked for adequacy and approved by the city. To the extent necessary for evaluation of the proposal, the plans may be required before approval of the tentative plan of a subdivision or partition. All plans shall be prepared in accordance with requirements of the city.

B. Improvement work shall not be commenced until the city has been notified and if work has been discontinued for any reason, it shall not be resumed until the city has been notified.

C. All required improvements shall be constructed under the inspection, and to the satisfaction, of the city. The city may require changes in typical section and details if unusual conditions arise during construction to warrant such changes.

D. All underground utilities and storm drains installed in streets shall be constructed prior to the surfacing of such streets. Stubs for service connections for all underground utilities and sanitary sewers shall be placed to such length as will obviate the necessity for disturbing the street improvements when service connections are made.

E. A map showing all public improvements as built shall be filed with the city recorder upon completion of the improvements. [Ord. 291 § 1, 2006; Ord. 215 § 49, 1994.]

The cost of such railroad crossing improvement including, but not limited to, the construction of signals, and other protective devices required by the public utilities commissioner, shall, except for that portion payable by the railroad company, be borne by the subdivider or partitioner.

F. Underground Utilities. All utilities shall be installed underground.

G. Street Lighting. Street lighting of an approved type shall be installed on all streets at locations approved by the city.

H. Street Name Signs. All streets shall be legibly marked with street name signs, not less than two in number at each intersection, according to specifications furnished by the public works superintendent.

I. Street Trees. Street trees shall be required by the city. The number, kind and location shall be determined by the planning commission in accordance with solar access provisions.

J. Improvement of Easements. Whenever the safety of adjoining property may demand, any easement for drainage or flood control purposes shall be improved in a manner approved by the city.

K. Off-Site Street Repair. Damage to public streets related to the development of the subdivision or minor partition, as determined by the public works superintendent, shall be repaired.

L. Water Quality Measures. Facilities such as storm water detention areas, bioswales, drywells, ditches, ponds, manmade wetlands, and similar water quality measures shall be incorporated into the development to meet federal or state storm water quality standards. [Ord. 291 § 1, 2006; Ord. 273 § 10, 2003; Ord. 215 § 50, 1994.]

17.30.030 Monuments.

A. All monuments shall be set according to the provisions of ORS 92.060. In making the survey for the subdivision or partition, the surveyor shall set sufficient permanent monuments prior to recording so that the survey or any part thereof may be retraced according to Oregon Revised Statutes.

B. Interior boundary and lot monuments for the subdivision or partition shall be marked by a registered land surveyor in accordance with ORS 92.060 and referenced in the plat. If the monuments are in place at the time the subdivision or partition is recorded, no performance bond is necessary. If monumentation is delayed beyond the date on which the subdivision is recorded, a bond must be posted to assure that the monuments will be set by a certain date, in accordance with ORS 92.065. The city shall determine the length of time and estimated amount of bond or cash deposit to guarantee payment of the cost of setting the interior monuments in the subdivision or partition. [Ord. 291 § 1, 2006; Ord. 215 § 51, 1994.]

17.30.040 Survey requirements.

A. The survey and plat of the subdivision or partition shall be made by a registered professional land surveyor, in accordance with ORS chapter 92 and other applicable state statutes.

B. The plat of the subdivision or partition shall be of such scale that all survey and mathematical information, and all other details, may be clearly and legibly shown thereon.

C. The survey for the plat of the subdivision or partition shall be of such accuracy that the linear error of closure shall not exceed one foot in 10,000 feet.

D. All dimensions to be in feet and decimals of a foot, to the nearest one one-hundredth of a foot.

E. In addition to showing bearing in degree, minutes and seconds of a degree and distances in feet and hundredths of a foot, the following curve information shall be shown on the subdivision or partition plat either on the face of the map or in a separate table:

1. Arc length;

2. Chord length;

3. Chord bearing;

4. Radius; and

5. Central angle.

F. The surveyor submitting any subdivision, condominium or partition plat that is within one-half mile of an established geodetic control monument, that has been approved by the National Geodetic Survey or has been approved by and filed with the county surveyor shall by field survey according to Federal Geodetic Control Committee guidelines for third order class II, show the measured angles and distances from the geodetic control monument to the initial point of a subdivision or condominium or to a monumented boundary corner of a partition. If there is an azimuth mark for the geodetic control monument or if there is another geodetic control monument that is intervisible to the primary geodetic control monument, the bearing shall be based, if practicable, on the bearings between the geodetic control monument and the azimuth mark or the intervisible geodetic control monument.

G. Notwithstanding the provisions of subsection F of this section, the county surveyor may waive the requirement of a distance and bearing to a geodetic control monument if the subdivision or condominium, or partition thereof, has previously furnished the required information. [Ord. 291 § 1, 2006; Ord. 215 § 52, 1994.]
