Norfolk, VA: Lafayette River Land Cover

This landcover data set helps to visualize the surrounding area and its uses.

Project Site: Rogers Hall Shoreline

These areas of land will help in designing the living shoreline and flooding parking lot.

Map measurements

To analyze site characteristics and determine the suitability of potential solutions, the team has evaluated site map parameters following the guidance of the Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments by the Virginia Institute of Marine Science (VIMS, 2010).

Physical traits

Shoreline orientation: SE

Shore length: 85 m

Shore morphology: Irregular

Nearshore Morphology:

Bars: None
Tidal Flats: None

(Google Earth)

Average fetch

Distance to the far shore along five lines, one perpendicular to the shore and two at 22.5 degree angles on either side. Useful for determining the wave energy of the shoreline.

298.12 ft = 0.056 mi

Longest fetch

Distance to the farthest shore.

Determined in ArcGIS.

0.29 mi

Depth offshore

Depth offshore: 0.5 - 1 m

Nearshore: 0.5 - 1 m
Bank height: 0 - 5 ft

Tide range

Mean tide range: 2.5 - 3 ft (Hardaway, 2018)
Great diurnal (spring) tide ranges: 2.5 - 3 ft (Hardaway, 2018)
Mean Lower Low Water (MLLW): 2 ft (NOAA Tides and Currents)

Erosion rate

EPR 1937/38 and 2017:

Very Low Accretion: +1 to 0 (ft/yr)

(Shoreline Studies Program)

Storm surge

100 yr (1% chance of occurring any given year)
- Relative to NAVD88: 8 ft (FEMA Flood Insurance Rate Maps)
- Elevation Difference between NAVD88 and MLLW: 1.8 ft (Norfolk Naval Shipyard - NOAA Tides and Currents)
- BFE relative to MLLW: 8 + 1.8 = 9.8 ft (Hardaway, 2018)
