General Description
Short Road has ditches along both north and south sides of the road. Actually, along some of the north side of the road there are 2 parallel ditches. Additionally, the remains of a stream that used to be the boundary between 2 farms (depicted on this 1954 USGS map), feeds into the north ditch. Water from the ditches on both sides of the road flows into the DelDOT ditch along Kent Ave; this ditch drains thru a pipe under Kent Ave to the other side of the road, and ultimately to the wetlands adjacent the Assawoman Canal. There used to be a culvert on the west side of this fence (on DelDOT property); this culvert partially collapsed in 2002(?), and DelDOT dug it up, leaving a ditch behind. The shocking thing about this approximately 25' long culvert was that it had nearly 2 feet of fall, which is extremely high for our community. (One end was at 1.77' elevation; the other was 3.73') This partially explains why the ditch on the north side of Short Rd is so much higher than the south side. (MBA installed the wooden bicycle/footbridge that crosses this ditch in 2003.) Past work |

This can happen even if the downstream system is free-flowing.

Detailed surveying work on the south ditch was done in the spring of 2008.
Jim Moneymaker (18 Short) indicated he wanted to bury the ditch in front of his property,
and requested appropriate elevation information from the MBA.
He was given elevations for the entrance and exit parts of his pipe, and asked to keep the ends at least 10' from each adjacent property line so as to minimize the impact on his neighbors.
In addition, he installed a surface drain near the middle of the pipe's run.
MBA drainage work was started on this stretch during the spring of 2009. On the south side of the road, the westernmost roughly 200' was buried in 12" PVC pipe. Two surface drains were installed along this length, feeding into PVC T's in the buried pipe. Other driveway culverts were replaced. Click here for detailed info about the MBA work on this ditch. The easternmost driveway culvert at #6, being part of a nice block wall, was left in place. It's a bit too low, so the penalty at this time is that the ditch in front of this property will hold water longer than it should. The culvert could be raised, and the walls could be rebuilt (it's actually alot easier than it sounds), but this isn't a high priority. At the same time, the ditch on DelDOT property was made closer to level, and the first 100' of ditch on the north side was buried in 12" PVC pipe. One surface drain was installed. This extended the buried pipe to the end of the straight part of this ditch, before the old stream splits off to the northeast. Major Work (2010) The single culverts at #12 and #14 were replaced, and both culverts at #16. The property owner at each of #14 paid MBA to bury an additional 60' of the ditch in front of their houses, in addition to installing a surface cleanout/drain. As noted above, the ditch at #18 has been buried in a culvert by the property owner. The elevations provided to the owner for this culvert were determined in order to allow the 2 driveway culverts at #20 to remain undisturbed, which is good, because one of the culverts has its side embedded in concrete. After the work is done on #12, 14 and 16, the upper part of the ditch will be evaluated to determine if further work is warranted. |

January 2012 Work
January wprl included backfilling around both cleanout boxes, then tieing into both the old stream, and the culvert recently installed by the homeowner under the driveway at 3 Short. A second box will be installed to replace the T currently in place (12/16/11). Rip rap will be installed on the west end of #3's culvert. 5 Short has a single wide driveway, and the original culvert was extremely deep (actually, we only found the very top of downstream end); A new pipe of the same length was installed substantially higher and slightly closer to the street. Much of this stretch of the ditch has a very thick accumulation of leaves and pine needles, so this will be cleaned out before any decisions are made about adjusting the ditch elevation. |
A cleanout/junction box similar to those at the downhill ends of Addy and Bridge Roads, was installed in June 2011 on MBA property near the SE corner of 1 Short. |

Future Work
North side: determine exact path of new main ditch. South side: verify existing culverts at upper end are OK; likely no work needed. |
