Area Surface Water Runoff
photos after August 2009 rainstorm |
|
Drainage channel behind Seaside Village
Water from the rear parking lot makes its way along 3 stone channels. These channels were installed about 4 years ago as a way to keep the mulch from washing into the road. |
Seaside Village Rear Parking
Grass adjacent the east side of the fence keeps the parking lot from draining rapidly. It is not necessarily a bad thing that the runoff is slowed down in this fashion.
Behind Seaside Village
Due to an accidental dip in the asphalt of about 1/2", much of the runoff from Seaside Village's back parking lot makes its way across Beach Plum Road, and eventually into the ground or into our ditches, which ultimately feed into the Assawoman Canal (NOT towards the Anchorage Basin). |
Corner of Evergreen and Beach Plum
Water ponds as it makes its way to DelDOT's drain near the Bennett Realty parking lot. |
Corner of Evergreen and Rt 1
3" deep puddle develops because the grass height keeps water from instantly flowing into the surface drain (which is located just to the right of the Bennett Realty sign). |
Adjacent E. Evergreen Gate
Water collecting just west of the highway gate. Five surface drains on the east side of Coastal Highway are located near the middle of each block |
E. Evergreen Gate Area
Small swales at each side of this picture allow water to flow to the highway, while keeping the middle pathway from becoming submerged. MBA intended to install new landscaping in this area in April 09, but held off due to nearby construction of a new house and also to see what could be learned from the Runoff Assessment |
Errett Gate
Ponding on the west side of the highway gate |
E. Errett Rd gate area
A small swale has been dug near the left side of this photo, allowing surface water to get under the highway fence. |
Median Grate between Bayberry and Errett
The fact that the concrete holding the steel grate is slightly higher than the surrounding catch basin is another accidental design that is a good thing. |
Median Grate near Addy
Note that the accidental accumulation of dead grass keeps water from quickly entering the storm drains. Again, slowing down the water is not necessarily a bad thing, although counting on dead grass accumulation is not very reliable.
Median Grate between Bridge and Errett
More dead grass doing a good thing. |
Dune Rd near #39
Water ponding on Dune Road, because it has no place to go. |
Dune Rd near #49
Ditto |
Highway drain near Errett Shoulder
Not terribly evident in this photo is the collection of needles/pinecones just beyond the drain pipe that is slowing down the runoff.
Pinecone Dam near Errett shoulder drain
Another view of the same thing |
Shoulder of Rt. 1 near E. Errett
|
E. Addy Rd gate area
East side of the gate, showing minor standing water adjacent the plantings (installed by nearby homeowners several years ago) at this gate. |
Rt 1 median at Bayberry
Note the puddle in the grass between the wayway and turn area. There is no drainage pipe under this walkway, as there are at most other median crossings.
E. Bayberry Rd Gate Area
Major ponding, because the water has no place to go. |
