Living Shoreline Design Information

Site Plans/Drawings
Three types of plans/drawings must be submitted with your application to accurately depict living shoreline restoration project activities: (a) Plan View, (b) Elevation/Cross Section View, and (c) Vicinity Map. Drawings do not have to be prepared by an engineer, but given the complexity of many living shoreline projects, professional assistance may be necessary. Construction plans must be submitted to the Waterway Permits Division of the Maryland Department of the Environment.
Plan View
The Plan View shows the proposed activity as if you were looking straight down on it from above. Your plan view should clearly show the following:
- Name of waterbody (river, creek, lake, wetland, etc.) and river mile (if known) at the location of the activity.
- Existing shorelines.
- Mean high and mean low water lines and maximum (spring) high tide line in tidal areas.
- Ordinary high water line and ordinary low water line if the proposed activity is located on a non-tidal waterbody.
- Average water depths around the activity.
- Dimensions of the activity and distance it extends from the high water line into the water.
- Distances to nearby Federal or State projects if any.
- Distance between proposed activity and navigation channel, where applicable.
- Delineation of any wetland (marshes, swamps, tidal flats, 100-year flood plains, etc.)
- North arrow.
- Scale.
- Description of dredged material involved. You must describe the type of material, number of cubic yards, method of handling the location of till and spoil disposal area, and the types of dredging. The drawing should show proposed retention dikes, weirs, and/or other means for retaining hydraulically placed materials.
- Mark the drawing to indicate previously completed portion of the activity.
- Mark the drawing to indicate storm water management facilities for marinas, residential and commercial developments.
Elevation/Cross Section View
The elevation and/or cross section view(s) are scale drawings that show the side, front or rear of the proposed activity. If a section view is shown, it represents the proposed structure as it would appear if cut internally or display. For projects with more than one habitat type or that change significantly over the length of the project, more than one elevation/cross section view is recommended. For example, one might present a cross section for both a sill section and a section in the center of a window/tidal gate. Your elevation/cross section view(s) should clearly show the following:
- Water elevations as known in the plum view (mean high water line, mean low water line, etc.)
- Water depths in the area of the proposed activity. If dredging is proposed, dredging depths and estimated disposal quantities.
- Cross-section of excavation or fill, including approximate side slopes.
- Cross-section of any structures (e.g., sills, marsh toe revetments)
- Graphic or numerical scale.
- Principal dimensions of the activity.
Vicinity Map
You may use an existing road map or US Geological Survey topographic may (scale 1:24,000) as
the vicinity map. Please include sufficient details to simplify locating the site from both the
waterbody and from land. Maps should show:
- Location of activity site (draw an arrow showing the exact location of the site on the map).
- Latitude, longitude, and river mile, if known.
- Name of waterbody and the name of the larger creek, river, bay, etc. into which the waterbody drains.
- Names, descriptions and locations of major roads and/or landmarks.
- North arrow.
- Scale.
Other Notes on Site Plans/Drawings
- Names of adjacent property owners who may be affected should be shown on the drawings.
- A legal property description including the number should be shown on the drawings.
- In the title block of each sheet of drawings, identify the proposed activity and include the name of the body of water; river mile (if applicable); name of county; name of applicant; number of the sheet and total number of sheets in the set; and the date the drawing was prepared.
