This chapter shall be known and may be cited as the Cowlitz County Grading Ordinance. [Ord. 04-135, § 1, 6-22-04.]

16.35.020 Purpose.

This chapter is intended to provide uniform procedures authorizing and regulating excavation, grading and earthwork activities within the unincorporated area of Cowlitz County. While not intended to duplicate other regulations, these regulations are designed to aid in controlling erosion incident to grading activity, and to protect public health, safety and welfare through the adoption and enforcement of provisions designed to:

A. Minimize adverse impacts associated with the excavation and grading of land;

B. Protect water quality from the adverse impacts associated with erosion and sedimentation;

C. Ensure prompt development, restoration, replanting, and effective erosion and sedimentation control of property during and after grading activities;

D. Establish administrative procedures for the issuance of permits, approval of plans, and inspection of grading operations; and

E. Allow for the reasonable development of land in Cowlitz County. [Ord. 04-135, § 2, 6-22-04.]

16.35.030 Authority and administration.

The Director of Building and Planning shall administer, interpret, and enforce this chapter. The Director shall have the authority to issue permits and to perform, or cause to be performed, inspections and take such actions as may be required to enforce the provisions of this chapter. [Ord. 04-135, § 3, 6-22-04.]

16.35.040 Applicability.

Unless exempted under CCC 16.35.050, no person shall perform any grading activity without having first obtained a permit from the Department. Exemption from the permit process shall not relieve any person the requirement for installation of appropriate erosion control measures for their project. No permit or exemption granted pursuant to this chapter shall remove applicant’s obligation to comply in all respects with the applicable provisions of any other federal, state, or local law or regulation. [Ord. 04-135, § 4, 6-22-04.]

If required, assessment and reports shall be completed in compliance with Chapter 19.15 CCC, the Cowlitz County Critical Areas Protection Ordinance. [Ord. 04-135, § 7, 6-22-04.]

16.35.080 Grading standards.

Unless otherwise recommended in the approved soils engineering or engineering geology report, grading shall conform to the following standards. Erosion control measures may be installed as outlined in Appendix A attached to the ordinance codified in this chapter, unless otherwise recommended by a project engineer.

A. Appropriate erosion control structures shall be installed prior to any grading activity. All erosion control measures shall be maintained in place until vegetation is established for suitable erosion and sedimentation control. No sediment from grading operations shall be permitted to leave the site or enter any surface waters or wetlands.

B. Sites shall have a finished grade that drains away from structural foundations for a minimum of 10 feet.

C. All sites shall be cleaned upon project completion, including installation of permanent organic erosion control measures such as grass seeding, landscaping, or other organic means of erosion control.

D. Cuts or fills of five feet in depth or greater shall be set back from property lines by a minimum of 25 feet. This can be decreased with appropriate engineering. Setback dimensions shall be horizontal distances measured perpendicular to the site boundary.

E. The top of cut slopes shall not be made nearer to a permit area boundary line than one fifth of the vertical height of cut with a minimum of two feet and a maximum of 10 feet. The setback needs to be increased for any required interceptor drains.

F. The toe of fill slopes shall be made not nearer to the permit area boundary line than one-half the height of the slope with a minimum of two feet and a maximum of 20 feet.

G. The Director may approve alternate setbacks at the request of the applicant. In approving these alternate setbacks, the Director may require an investigation and recommendation by a qualified engineer or engineering geologist to demonstrate that the intent of this section has been satisfied.

H. Any proposed finished slope that is steeper than two horizontal to one vertical shall be engineered.

I. The ground surface shall be prepared to receive fill by removing all organic material, non-complying fill, and scarifying topsoil.

J. Solid waste as defined in Chapter 15.30 CCC, Solid Waste Management, and detrimental amounts of organic material shall not be used as fill material.

K. Fill slopes shall not be constructed on natural or cut slopes steeper than two units horizontal in one unit vertical (50 percent slope) unless engineered. The ground surface shall be prepared to receive fill by scarifying to provide a bond with the new fill and, where slopes are steeper than five units horizontal in one unit vertical (20 percent slope) and the height is greater than five feet, by benching into sound bedrock or other competent material as determined by the engineer.

L. All fills shall be compacted to a minimum of 90 percent of maximum density, unless approved as a waste site by the Director.

M. The slope of cut or fill surfaces shall be no steeper than two units horizontal in one unit vertical (50 percent slope) unless the permittee furnishes a geotechnical engineering or an engineering geology report or both, stating that the site has been investigated and giving an opinion that a cut at a steeper slope will be stable and not create a hazard to public or private property.

At the request of the applicant, the Director may approve the use of alternate grading standards. These approvals shall be based on sound engineering practices and may require the submittal of additional documentation, reports, or testing. [Ord. 04-135, § 8, 6-22-04.]

16.35.090 Grading inspection.

An inspection schedule shall be established for each project prior to permit issuance based on the following:

A. A civil engineer shall provide professional inspections within such engineer’s area of technical specialty, which shall consist of observation and review as to the establishment of line, grade and surface drainage of the development area. If revised plans are required during the course of the work, they shall be prepared by the civil engineer.

B. A geotechnical engineer and/or engineering geologist shall provide professional inspection within such engineer’s area of technical specialty, which shall include observation during grading and testing for required compaction. The engineer shall provide sufficient observation during the preparation of the natural ground and placement and compaction of the fill to verify that such work is being performed in accordance with the conditions of the approved plan and the appropriate requirements of this chapter. He or she shall also provide professional inspection of any excavation to determine if conditions encountered are in conformance with the approved report or plan. Revised recommendations relating to conditions differing from the approved engineering geology or geotechnical reports shall be submitted to the permittee, the Department, and the civil engineer.

C. The permittee shall be responsible for the work being performed in accordance with the approved plans and specifications and in conformance with the provisions of this chapter. When approved by the Director, the permittee may engage consultants, if required, to provide professional inspections on a timely basis. The permittee shall act as a coordinator between the consultants, the contractor and the Department. In the event of changing conditions, the permittee shall be responsible for informing the Department of such change and shall provide revised plans for approval.

D. The Department may inspect the project in various stages of work.

E. If, in the course of fulfilling their respective duties under this chapter, the civil engineer, geotechnical engineer, or engineering geologist finds that the work is not being done in conformance with this chapter or the approved grading plans, the discrepancies shall be reported in writing within three working days to the permittee and to the Department.

F. If the civil engineer, geotechnical engineer, or engineering geologist of record is changed during grading, the work shall be stopped until the replacement has agreed in writing to accept the responsibility within the area of technical competence for approval upon completion of the work. It shall be the duty of the permittee to notify the Department in writing of such change prior to the recommencement of such grading. [Ord. 04-135, § 9, 6-22-04.]
