11.35.010 Design.

Extensions to the sewer system shall be made in conformance with the GSP.

All sewer system extensions shall be designed by a civil engineer licensed to practice engineering in the state of Washington. The design shall be in accordance with the Design and Construction Standards established pursuant to EMC 11.30.060, this title, the GSP, the Orange Book, and the Standard Specifications.

In general, sewers shall be located below all other utilities in rights-of-way to provide the greatest opportunity for adjacent properties to connect thereto by gravity building sewer and side sewer, and minimize the opportunity for contaminating other utilities from leaks. Consideration for adequate cover and separation, potential sizing for water and storm drains, required slopes for side sewers, and adequate clearance for workers results in a minimum depth for gravity sewers, located in public rights-of-way, of 10 feet as measured from finished grade to sewer crown. This necessary depth shall be maintained unless the director finds, in writing, that after taking into consideration all the above, a shallower depth is justified.

Manhole lids, located in the traveled way, shall be placed at lane lines or in the center of left-turn lanes. (Ord. 06-271 § 1).

11.35.020 Separation from water lines.

A minimum horizontal separation of 10 feet between sanitary sewers and any potable water lines, and a minimum vertical separation of 18 inches between the bottom of the water line and the crown of the sewer, shall be maintained. The distances shall be measured outside edge to outside edge.

When local conditions prevent the separations described above, the director may approve an alternative; provided, that no such alternative shall be less restrictive than that provided for in the Orange Book C1-9.1. (Ord. 06-271 § 1).

11.35.030 City-owned sewage pump stations.

Sewage pump stations shall be prohibited unless the director finds there is no reasonable alternative. Pump stations shall be designed and constructed in conformance with the Design and Construction Standards, this title, the Orange Book, and the Standard Specifications. Pump stations shall be designed and constructed to minimize operation and maintenance costs and employee exposure to health and safety hazards. Permanent on-site electric generators, with power generation adequate for full function of the pump station, shall be installed at every city sewage pump station. A force main shall discharge into a manhole and not directly into another force main or gravity sewer pipe. (Ord. 06-271 § 1).

11.35.040 Cross-connection control.

Sewage pump stations and all other sewer system elements with water service shall be required to meet the requirements of the water purveyor, the Cross-Connection Control Manual, and WAC 246-290-490. (Ord. 06-271 § 1).

11.35.050 Plans and specifications.

The plans and specifications shall be prepared in accordance with the Design and Construction Standards, this title, the GSP, the Orange Book, and the Standard Specifications. (Ord. 06-271 § 1).

11.35.060 Easements.

All easements shall be in a form as provided by the city or as approved by the city prior to negotiation, must be reviewed and approved prior to execution, and shall require written acceptance by the city prior to recording. The director may, in his/her sole discretion, by written approval waive any of the easement requirements set forth in this section upon the director’s determination that such waiver would not adversely affect the city’s interests.

A. Permanent Easements.

1. The purpose(s) for the easement and the permitted activities shall be stated.

2. All sewers shall be located in dedicated rights-of-way or easements. The minimum width of an easement shall be 20 feet plus two feet for every foot of sewer depth over 10 feet, unless otherwise approved by the director.

3. All-weather access improvements, capable of being negotiated by a fully loaded vactor truck (H-20 load), shall be provided to every manhole, air-vac relief station, pigging port or other appurtenance requiring maintenance access.

4. City access to and across the easement shall be unrestricted. Buildings, trees, parked vehicles, and all other structures, except as otherwise provided herein, shall be prohibited within easements. Private driveways may be located within city easements. In the event the director determines that private fencing across an easement is necessary and reasonable, such fencing may be permitted; provided, that double-leaf gates with a nominal width of 20 feet are provided at fence crossings. The owner may install only landscaping improvements that have been approved by the city.

5. Easements shall be maintained by the city to city standards. Landscaping improvements installed by the owner shall be maintained by the owner. The city may cut back or remove landscaping improvements, as it deems necessary. The city shall have no obligation to repair or replace landscaping improvements that have been damaged or removed.

6. The city shall have the right to issue permits to third parties to operate and maintain side sewers within the easement.

7. Pump stations shall be located on property that has been deeded to the city unless otherwise approved by the director. Easements for pump stations shall be unrestricted and exclusive.

B. Temporary Easements. Temporary easements obtained for construction, staging, storage, or temporary access shall:

1. Identify use or uses;

2. Set the term and provide for extensions thereto;

3. Contain specific conditions for restoration and a one-year warranty for such restoration;

4. Contain provision for the owner to inspect the condition of the easement property following completion of restoration; and

5. Provide for the owner’s release following such inspection. (Ord. 09-317 § 2; Ord. 06-271 § 1).

11.35.070 Construction.

All construction shall be in conformance with the Design and Construction Standards, this title, the GSP, the Orange Book, and the Standard Specifications. Contractors shall have a current and valid state of Washington contractor’s license and a city of Edgewood business license. Construction shall not commence until a preconstruction conference, meeting the requirements set forth in the Design and Construction Standards, has occurred. (Ord. 06-271 § 1).

11.35.080 City projects.

Nonemergency sewer system extension projects constructed with city funds shall first be identified in the GSP and included in the city’s CIP. Such projects shall be paid for with connection and/or rate charges from users of the sewer system together with any grants and loans that may be obtained.

All city sewer system extension projects must meet the bidding requirements of the city’s purchasing policy and RCW 35.23.352. All city sewer system extension projects are public works projects and are subject to prevailing wage requirements as set forth in Standard Specifications 1-07.9.

The following are additional requirements of all city sewer system extension projects:
