The purpose of this chapter is to establish and define the improvements which will be required under agreement to be constructed by the subdivider as conditions for final plat approval, to delineate those areas within the city which will require a specific degree of improvement to be accomplished, and to outline the procedures and responsibilities of the subdivider and the appropriate public officials and agencies covered with the administering, planning, designing, constructing and financing of public facilities, and to further establish procedures for assuring compliance with these requirements.

All required periphery and access streets shall be constructed or improved in accordance with the comprehensive plan. (Ord. 255 § 3, 1982)

12.12.070 Erosion and sedimentation plan.

In the event that any developer shall intend to denude or recontour any land proposed to be subdivided, by means of grading, excavation or the removal of or destruction of the natural topsoil, trees, or other vegetative covering thereof, a plan for erosion and sedimentation control shall be submitted to the city manager for approval prior to any recontouring or denudation being done unless there has been prior determination by the platting authority that such a plan is not necessary. Such plans shall contain adequate measures for control of erosion and siltation, where necessary, using the guidelines and policies contained herein. These plans shall be reviewed by the city manager and, if approved, shall be followed as the plans indicate. If the measures required to control erosion and siltation construction are necessary, such construction shall be a part of the street improvement agreement. The following control measures should be used for an effective erosion and sediment control plan:

A. The smallest practical area of land should be exposed at any one time during development.

B. When land is exposed during development, the exposure should be kept to the shortest practical period of time.

C. Sediment basins (debris basins, desilting basins or silt traps) should be installed and maintained to remove sediment from runoff waters from land undergoing development.

D. Provisions should be made to effectively accommodate the increased runoff caused by changed soil and surface conditions during and after development.

E. Groundcover should be replaced as soon as practical in the development.

F. The development plan should be fitted to the topography and soil conditions so as to create the least erosion potential.

G. Wherever feasible, natural vegetation should be retained and protected.

H. All slopes within a subdivision resulting from cut and fill operations shall not exceed a maximum slope of 50 percent unless a lesser slope is deemed necessary by the city manager due to soil conditions. If slopes of greater than 50 percent are desired, such slopes will be supported by a retaining structure approved by the city. (Ord. 255 § 3, 1982)

12.12.075 Guarantee of completion.

Prior to final approval and recording of any subdivision requiring public improvements, the subdivider shall enter into a street improvement agreement with the city. (Ord. 255 § 3, 1982)

12.12.080 Variances authorized.

The city council may grant a variance from the provisions of these regulations. The city council shall only grant variances that it deems necessary, or which it finds desirable from the standpoint of public interest. In making its findings, as required in this section, the city council shall take into account the nature of the proposed use of the land and the existing use of land in the vicinity, the number of persons to reside or work in the proposed subdivision, and the probable effect of the proposed subdivision upon conditions in the vicinity. No variance shall be granted unless the city council finds the following contained in subsections (A), (B) and (C) of this section:

A. That there are such circumstances or conditions affecting said property that the strict application of the provisions of this chapter would clearly be impractical, unreasonable or undesirable to the general public. In such cases, the subdivider shall first state his reasons in writing to the specific provision or requirement involved and submit them to the city council. The subdivider bears the burden of proof.

B. That the granting of the specific variance will not be detrimental to the public welfare or injurious to other property in the area in which said property is situated.

C. That the granting of the specific variance will not have the effect of nullifying the intent and purpose of this title or the comprehensive plan.

D. The city council shall include its findings and the specific reasons for its action and shall also record its reasons and actions in its minutes. (Ord. 596 § 3, 2002; Ord. 255 § 3, 1982)
