Reclaiming the North End Erosion Pit

BIAC has on its north-west end a pit created by erosion of the land due to years of tidal action and outflow from two (now abandoned) Redwood City service pipes. The total sq ft that could be reclaimed is less than 1500 sq ft, requiring less than 500 cu yd of fill.


A similar and somewhat larger erosion pit exists on RWC property again to our north-west.

BIAC seeks to reclaim former land by filling in the erosion pit with materials approved by the Army Core of Engineers such as riff raff and soil. Redwood City Engineering approves of our idea as it will be a part of solving a high tide storm drain backflow problem on Maple St.

The property at 1450 Maple might look like this:

BIAC would use this reclaimed land for the storage of kayaks, canoes, and rowing shells. It is hoped that our landlord, Cemex, will not only approve of this improvement but also donate the materials.

From another angle (plane vs satellite) the current property could look like this. For an close up photo tour of the current erosion pit, you can see these photos;

  1. A close up of the former RWC treatment plant 30" corrugate pipe now only used to drain the BIAC parking lot storm drain. It will back up onto Maple St at 11'+ high tides. RWC Engineering has suggested the following drawing, which would work well in a plan to fill in the erosion pit.
  2. From outside of the clubhouse north exit, this is the view to the north towards Docktown. Note that picture A is encompassed in this view.
  3. A view to the south east from the northern most extreme of the BIAC property. Note an existing but decrepit seawall installed when the RWC treatment plant was still operative (now moved to Redwood Shores).
  4. From the waterway looking west one can see two 30" corrugated pipes in disuse and the extent of the land erosion that has occured over fifty or so years.
