All grading permits applications shall contain the information described below in addition to the standard application information required under BMC Title 11, Administration of Development Regulations, and shall include:

A. Completed application form and attachments signed and dated by owner/agent.

B. General vicinity map of proposed site.

C. Site plan(s) depicting proposed and existing improvements on the property. The site plan shall contain the following information:

1. Property limits and surveyed or accurate contours of existing ground and details of terrain and area drainage;

2. Limiting dimensions, elevations or finish contours to be achieved by the grading, and proposed drainage channels and related construction;

3. Location of any buildings or structures on the property where the work is to be performed and the location of any buildings or structures on adjacent lands that are within 15 feet of the property or which may be affected by the proposed grading operations;

4. Amount of hard surface cover as defined under BMC 11.02.009 and regulated under BMC 12.14.030 and 12.14.040;

5. Topography contours shall be shown at two-foot intervals or at five-foot intervals for slopes greater than 15 percent and 10-foot intervals for slopes greater than 40 percent on the horizontal contour plan. Existing contours shall be drawn as dashed lines, proposed contours as solid lines. Grading plans and specifications proposing to involve more than 5,000 cubic yards of fill or excavation must be designed and stamped by a Washington State licensed civil engineer;

6. Traffic control measures if the work to be done is near or within a right-of-way and for hauling equipment which is entering and leaving the site;

7. A schedule for street cleaning that includes the entire construction schedule;

8. Location of the proposed disposal site for any excavation to be hauled off site;

9. A temporary erosion and sedimentation control plan (TESCP) in accordance with the Bothell Standards;

10. Drainage report prepared in accordance with Chapter 18.04 BMC;

11. A storm water and drainage control plan prepared in accordance with Chapter 18.04 BMC; and

12. Surface water pollution prevention plan (SWPPP) consistent with the Bothell Standards.

13. All plans shall be prepared consistent with the Bothell Standards; and

14. All plans shall be prepared consistent with the provisions of Chapter 12.14 BMC.

D. Grading permit applications that are classified as Type II development permit applications shall submit the following additional materials:

1. Detailed plans of all surface and subsurface drainage devices, walls, cribbing, dams and other protective devices to be constructed with, or as a part of, the proposed work, together with a map showing the drainage area and estimated runoff of the area served by any drains;

2. Recommendations included in the soils engineering report and the engineering geology report shall be incorporated in the grading plans or specifications. When approved by the director, specific recommendations contained in the soils engineering report and the engineering geology report, which are applicable to grading, may be included by reference;

3. Dates of soils engineering and engineering geology reports, together with the names, addresses and phone numbers of the firms or individuals who prepared the reports;

4. SEPA checklist for grading more than 500 cubic yards or for any grading occurring within a critical area or buffer as defined in the critical area ordinance, Chapter 14.04 BMC;

5. Soils engineering report for grading activities occurring within critical areas or when more than 500 cubic yards of material is proposed to be moved;

6. Liquefaction study for projects that are in or adjacent to landslide and erosion hazard areas as noted in the critical areas regulations of Chapter 14.04 BMC or where all of the following three conditions are present:

a. Shallow ground water, 50 feet or less;

b. Unconsolidated sandy alluvium; and

c. Seismic zones D1 and D2. Note: Generally, land within the city of Bothell is classified as a seismic zone D2;

7. Pavement restoration plan for Type II permits if such plan is required by the city;

8. If work involves a critical area, submit a critical areas alteration permit application consistent with Chapter 14.04 BMC; and

9. Copies of the approved land use decision or entitlement such as, site plan, shoreline, variance, conditional use permit, short plat, preliminary subdivision, planned unit development, the issued SEPA determination, plus all applicable items required to be submitted with the grading permit application as identified within those entitlement decisions.
