e . compacted to 95% of Standard Proctor Density (ASTM D2922-78 and ASTM D3017-78), without additional moisture control, cured and tested in accordance with ASTL C31. 6. Backfill excavated areas and trenches under or within one foot of existing or proposed pavement with cement-stabilized sand. There shall be cement- stabilized sand from the top of the pipe up to a maximum of one foot below the paving subgrade. 7. The proposed location of any backfill other than cement stabilized sand backfill shall be shown by stations in the drawings in both plan and profile views. 8. Public sanitary sewers and force mains shall be located in either the public right- of-way or public easements. Side lot and back lot easements are discouraged and should be avoided. Side lot and back lot easements may be granted special approval only when a sanitary sewer located in the street right-of-way is impossible from an economic and engineering standpoint. a. Street Right-of-way (1) Sanitary sewers with a depth of up to ten feet (10' measured from finished grade), shall be placed within the right-of-way at least 5 feet from the right-of-way line. Said sanitary sewer should also be 5 feet from the paved area when achievable. All sanitary sewers that are deeper than 10 feet shall be centered in an exclusive public easement parallel to and adjoining the street right-of-way. Where the City of La Porte deems the need, the .Professional Engineer of Record may be required to provide additional public easement adjoining the street right-of-way to accommodate either horizontal or vertical clearances. b. Easements (1) The maximum depth of a sewer in a side lot or back lot easement shall be 8 feet where and if the use of side or back lot easements are approved. (2) Easements shall have a minimum of 2 access points for maintenance purposes. c. Lateral Location of Sewer in Right-of-Way/Easement (I) The location of the sanitary sewer within a dedicated public easement shall be along the centerline of the proposed public easement or as close to the centerline as can be designed. In those instances where the public easement is adjacent to the public right-of-way, the lateral location of the sanitary sewer shall be at the discretion of the Design Engineer with City approval. 9. The final determination as to that portion of a street, alley, or public easement to be occupied by a proposed sanitary sewer rests with the City. The City will take into consideration existing, planned and proposed facilities such as manholes, pavement, pipes/conduits, along with existing trees and shrubs, historical features, wetlands or other unique surface conditions when arriving at a decision. 10. The drawings of the sanitary sewer shall show the location of any existing pipe or duct that might interfere with the construction of the sanitary sewer and call Sanitary Sewer Design Criteria Page 6 of 11
