This project was funded by the Virginia Coastal Zone Management Program at the Department of Environmental Quality
through Grant #NA08NOS4190466 of the U.S. Department of Commerce, National Oceanic and Atmospheric
Administration, under the Coastal Zone Management Act of 1972, as amended. The views expressed herein are those

Figure 2-4. Photos showing nearshore bars and submerged aquatic vegetation. A) A VGIN 2009 photo
shows the channel into Cranes Creek in Northumberland County, Virginia. Sand bars north of the channel
will attenuate waves while the shoreline adjacent to the channel has no bars and will feel the full effect of
the waves impacting the shoreline. B) A VIMS aerial photo of Pond Point on the East River in Mathews,
Virginia (dated 21 April 2009) showing extensive SAV in the nearshore, as well as sand bars.

Figure 2-5. Map depicting the elevation difference between NAVD88 and MLLW in Chesapeake Day.
Data calculated using NOAA’s VDATUM grids. Datum transformation grid TSS was subtracted from
the MLLW datum transformation grid (http://vdatum.noaa.gov/dev/gtx_info.html) to obtain the
elevation differences.

• shellfish lease holders

• financial supporters

8. Document Site Conditions - conduct necessary or suggested environmental studies

• tree survey, tree preservation and removal plan

• wetland delineations, tidal and non-tidal

• Refine topography and bathymetry

• Mean Low Water survey,

• sediment samples, subtidal, intertidal, upland bank

• protected species

9. Modify project concept plan as needed based on pre-application review and environmental
studies

10. Permit process plan - develop plan for simultaneous agency permit process, submission
and review requirements, what to expect, steps in the process, sequence, timeframe, public
hearing requirements

11. Communicate with property owner(s) to establish realistic expectations and understanding
of what the process entails including unannounced site visits by various parties, who will be
responsible for what (e.g. representation at public hearings, tolerance for project modifications,
sureties if required)

12. Prepare various applications as required, use most recent forms available

• Prepare Erosion and Sediment Control Plan, land disturbance permit application

• Prepare Water Quality Impact Assessment (WQIA)

• Prepare Joint Permit Application and drawings in 8.5x11 inch format

• Prepare Landscape restoration plan

13. Submit applications, project drawings and supporting documents to local government and
VMRC (as required)
