To the editor:
The algae and bioburden from the outfall onto King’s Beach could benefit from a few simple actions:
- Install a tight-fitting pile of blocks in line with the outfall at Eastern Avenue and Lynn Shore Drive to reduce the energy of incoming surf, especially during high tides during full moon storms. The storm surges go back into the outfall and send water and stones airborne when the steel covers dislodge. That inflow prevents free outflow of storm water. This likely contributes to damage/leaks and cross-contamination with sewer lines. Build the pile far enough out so that large waves would not wash people and dogs into the street. Fit these tightly so that no one could get caught in the cracks. Make the sides nearly vertical to discourage climbers. Place this in the triangular stormwater discharge zone only.
- Chesapeake Bay is using oysters to manage bioburden. Work with the oceanographers in Nahant to assess this option. Contact people doing this now and discuss available options for seed stock. Oyster reefs could preserve the shoreline and prevent erosion by acting as speed bumps for the incoming flow.
- Build a row of blocks or large boulders beyond the low-tide line where the ocean floor drops off (seen on topographical maps). Integrate this with oyster-bed placement. The area between Red Rock Park and the point at the Hawthorn should be examined. Place the row close enough to be effective, but far enough to not create risks to fishing and surfing.
These are suggestions for low-tech ideas that could be removed if ineffective. Limit the scope and budget. Start small. Expand if successful.
