24.50.010 General.

A. General Applicability. This chapter applies to all land disturbing activities, whether or not a permit is required.

All land disturbing activities shall comply with this chapter and the requirements set forth by SVMC Title 21, Environmental Controls, and 22.130.040, Street standards.

B. Purpose. The purpose of this chapter is to regulate all land disturbing activities to protect and safeguard the general health, safety, and welfare of the public residing within the City of Spokane Valley by:

1. Establishing procedures for issuance of permits, plan approval, and inspection of grading construction; and

2. Controlling erosion and preventing sediment and other pollutants from leaving the project site during construction by implementing best management practices; and

3. Reducing stormwater runoff rates and volumes, soil erosion and non-point source pollution, wherever possible, through stormwater management controls and to ensure that these management controls are properly maintained and pose no threat to public safety; and

4. Protecting downstream properties and public infrastructure.

C. Definitions.

1. “Applicant” is the private party or parties desiring to construct a public or private improvement within City right-of-way, easements, or private property, securing all required approvals and permits from the City, and assuming full and complete responsibility for the project. The applicant may be the owner or the individual designated by the owner to act on his behalf.

2. “Clearing and grubbing” includes, but it is not limited to, removing trees, stumps, roots, brush, structures, abandoned utilities, trash, debris, and all other material found on or near the surface of the ground in the construction area.

3. “Grading” is the physical manipulation of the earth’s surface and/or surface drainage pattern which includes surcharging, preloading, contouring, cutting, and/or filling. Grading activities fall into two general categories: engineered grading and regular grading.

4. “Land disturbing activity” results in a change in existing soil cover (vegetative or nonvegetative) or site topography. Land disturbing activities include, but are not limited to, demolition, construction, clearing and grubbing, grading and logging.

5. “Site” includes all the parcels included in the project.

D. Permit Required. A separate permit shall be obtained for each site. No land disturbing activity, unless specifically exempted, shall be performed without first having obtained a permit. The following are the types of permit:

1. Engineered Grading. Refer to SVMC 24.50.020 for general exemptions. Refer to SVMC 24.50.030 for applicability, additional exemptions, and permit requirements. All engineered grading shall comply with the Washington State Environmental Policy Act.

2. Regular Grading. Regular grading is grading work that is not required to be engineered. Refer to SVMC 24.50.020 for general exemptions. Refer to SVMC 24.50.040 for applicability, additional exemptions, and permit requirements.

3. Clearing and Grubbing Permit. Refer to SVMC 24.50.050 for applicability, exemptions, and permit requirements.

E. Fees. Permit fees, including plan review, shall be assessed in accordance with the currently adopted Spokane Valley master fee schedule.

F. Surety. The applicant shall post a surety in an amount determined by the development services senior engineer. Acceptable surety instruments are cash savings assignments and letters of credit issued by a duly chartered financial institution.

G. Inspection. All land disturbing activities shall be subject to inspection by the development services senior engineer. For all engineered grading permits, special inspection of grading operations and special testing shall be performed in accordance with the provisions of Chapter 9 of SVMC 22.130.040, Street standards.

If, during an inspection, site conditions and/or construction of permanent items are found to not be as shown in the permit application or approved plans, the permit may be deemed invalid. No land disturbing activity shall be undertaken, or continued, until revised plans have been submitted and approved.

The development services senior engineer shall be notified when work authorized by a permit issued subject to this chapter is ready for final inspection. Final approval shall not be granted until all work has been completed in accordance with the approved grading plans and any required reports have been submitted.

H. Hazards. If the development services senior engineer determines that any land disturbing activity has or may become a hazard to life and limb, endanger property, cause erosion, or adversely affect drainage, the safety, use, stability of a public way or drainage channel, the owner shall be notified in writing. The owner is responsible to mitigate the hazard within the time specified by the development services senior engineer. If not corrected, the land disturbing activity shall be deemed to be a violation pursuant to subsection I of this section.

I. Violations. Unless exempt, any land disturbing activity performed without a permit shall be considered hazardous and a public nuisance, subject to all enforcement actions and penalties as found in SVMC Title 17. An investigation fee may be assessed pursuant to International Building Code Section 108.4. The fee is payable prior to the issuance of a permit. Payment of the investigation fee does not vest the illegal work with any legitimacy, nor does it establish any right to any permit for continued development of the project.

Any person, firm, or corporation violating any of the provisions of this chapter shall be subject to fines as provided in SVMC Title 17.

J. Construction Stormwater Permit. The applicant shall contact the Washington Department of Ecology (Ecology) to determine if a construction stormwater permit is required.

K. Changes in the Field. Revised plans may be required when changes are made to the approved grading plans. Land disturbing activities affected by such changes shall not continue until the revised plans are reviewed and approved by the development services senior engineer. (Ord. 09-033 § 6, 2009).
