No part of a retaining wall may extend across a property line without a recorded Construction and Maintenance Easement. Show location of all easements. Show the location of the septic tank and field if applicable. In unincorporated areas retaining walls greater than 6' in height and retaining walls with guards or fences on top whose combined height is greater than 6' must meet yard zoning setback requirements from the lot lines. Complete cross-sectional drawing of wall to scale.
Elevation view from the low grade side of wall drawn to scale.
Guardrail details if applicable. The proposed retaining wall is located on a parcel of land containing a one or two family dwelling. Pre-approved modular block wall systems have been assigned a Master Plan Number by Public Works which must be quoted on your application for permit. Consult your modular block supplier for this master plan number and the cross-sectional drawing that matches your design. Retaining walls of greater heights, having greater surcharge loading and walls of different materials or designs than those specified above must be designed by a Missouri Licensed Professional Engineer.
