§ 1234.07 STORMWATER MANAGEMENT.

   (a)   Overall considerations. In all subdivisions and land developments proposed, storm drainage facilities shall be provided in order to:

      (1)   Permit unimpeded flow of natural watercourses;

      (2)   Ensure adequate drainage of all low points along the lines of streets;

      (3)   Intercept stormwater runoff along streets at intervals related to the extent and grade of the area drained;

      (4)   Provide positive drainage away from on-site sewage disposal; and

      (5)   Remove surface water from the bottom of vertical grades, lead water from springs and avoid excessive use of cross-gutters at street intersections and elsewhere.

   (b)   Stormwater management plan. Each subdivision and/or land development shall provide:

      (1)   Calculations of runoff concentration and the proposed stormwater management system;

      (2)   Complete drainage systems for the subdivision or land development; and

      (3)   Approval by the State Department of Transportation when drainage structures are to be located on state highway rights-of-way or connection is made to the existing state highway system.

   (c)   Further considerations. Further considerations and requirements are detailed in Chapter 1043 of the Streets, Utilities and Public Services Code.
