Generally, provide a minimum of six inches of vertical separation between storm drains and the sewer below the storm drain. Joints shall be located outside the storm drain trench. When the minimum cannot be maintained, plans will indicate installation of felt expansion material or equivalent between facilities. To protect the sewer main from distorting under extreme loads, other measures, such as concrete encasement, may be submitted for approval.
