Storm Drain Construction Notes

1. All public storm drainage systems shall be constructed in accordance with the latest edition of the Washington State Department of Transportation Standard Specifications for Road, Bridge, and Municipal Construction and the City of Longview Standard Plans and Specifications. 2. All public storm drainage system construction is subject to inspection and approval by the City Department of Public Works. The Contractor shall notify the City a minimum of two full business days prior to the start of construction. 3. The Contractor shall be responsible for determining the location of all underground utilities prior to the start of construction/excavation and shall notify the engineer of any potential conflicts. The Contractor is required to contact the Northwest Utility Notification Center a minimum of two full business days prior to the start of construction and/or any excavation at 811 or www.callbeforeyoudig.org. 4. Tracer wire shall be installed with all non-conductive pipes in one continuous strand. Tracer wire shall be minimum #12 AWG steel reinforced copper wire. The insulation color shall be green and its material shall be a minimum 30 mil composed of high density polyethylene (HDPE) or high molecular weight polyethylene (HMWPE). Secure the wire on the pipe with tape every 8-10 feet as needed to keep the wire straight and on top of the pipe. Install a green warning tape 12-18 inches above the pipe in the same orientation to the installed pipe. See SS-260 for locator box detail and requirements. Continuity testing of tracer wire is required. 5. To protect stormwater flow control and quality treatment facilities from sedimentation, they shall be connected to the storm conveyance system only after all site work, road construction, utility work and landscaping are in place in all areas above and upstream of the facility. 6. The existing storm sewer system shall stay isolated from the new system via mechanical plug until the new system is cleaned, tested, video inspected and approved for use. 7. Storm drain pipe shall be cleaned by use of high pressure nozzle and vacuum truck prior to video inspection. Video inspection shall be performed in an organized and sequential order as approved by the City Engineer. Video recordings shall be submitted on a CD, DVD, flash drive or similar media approved and accepted by the City. If debris is found to be in the lines, further cleaning will be required prior to acceptance.

8. All storm drain pipe shall be tested for deflection. Storm sewer constructed with flexible pipe shall be tested for deflection in accordance with section 7-17.3(2)G of the Standard Specifications. All pipe shall be constructed in accordance with section 7-04. 9. Deflections in flexible pipe shall not exceed 0.03 feet. 10. Pressure testing of all storm main lines is required in accordance with the Standard Specifications Section 7-04. 11. Vacuum testing all new storm manholes is required in accordance with ASTM Designation C 1244-93. 12. As-built drawings shall be submitted and approved prior to project acceptance. 13. Pipe bedding shall be per standard plan SS-240. 14. When the material at the bottom of an excavation is not suitable enough to support the structure, the contractor shall excavate below grade and replace the unsuitable material with gravel backfill. 15. Geosynthetic materials shall meet the requirements of WSDOT Standard Specifications 9-33.Geosynthetic materials shall be installed with all catch basins and manholes and shall be placed on undisturbed subgrade and below fill materials. 16. Unless otherwise approved a minimum cover of 24” is required above the top of the pipe to the top of the finish grade. There shall be a minimum of 12” separation from the top of the pipe to the bottom of the roadway section (e.g. laterals from catch basins). A minimum cover of 12” may be used for HDPE pipe diameters 18” or less in conditions not to exceed incidental H-20 loading, unless otherwise approved by the City Engineer. Minimum cover is measured from the top of the pipe to the bottom of flexible pavement or to top of rigid pavement. This standard assumes the pipe is installed in accordance with manufacture's recommendations and may not address the cover needed to prevent flotation. In every case where at least 12” minimum cover cannot be obtained, ductile iron or box culverts shall be used as approved by the City. 17. All storm sewer pipe which crosses water pipe shall be in accordance with Standard Plans W-290, W-295 or W-300 as applicable to the situation and approved by the Engineer.
