Yes, but this is the designated area - The pond is approx 5x15 maybe 2 foot deep with a feed from the underground system (1st pic) - it will overflow over the sidewalk when it fills, but is designed as a detention pond. - The builder actually referred to them as retention ponds - Not a ditch as it does not allow for continuous flow out - only when it overflows.
You can’t see it well in the 2nd photo but the bottom end is “closed”
A stormwater detention pond is an open basin built by excavating below ground or constructing above-ground berms or embankments. The detention pond temporarily stores stormwater runoff and slowly releases it through a specially designed outlet or control structure. Detention ponds typically are designed to drain completely within a few hours or days. Styles vary greatly, from well manicured to natural appearing. Generally, more natural-appearing vegetation is preferred for reduced maintenance and enhanced wildlife habitat. Some facilities are designed to appear as natural water bodies or park-like areas.
Here where I live it just holds the water until that water soaks into the ground, it does not go into the sewer system. The ditch might go up the whole block and around the corner then they just Dead End and a new ditch starts around the other half of the corner and continues (also with the piping you show under the driveway).
If they over flow then, oh well…ditch wasn’t deep enough. The city/county come and re-dig them about once a year.
Retention ponds are an aesthetically pleasing way to treat storm water runoff. Instead of letting rainwater go directly into storm sewers or waterways, retention ponds allow the water to sit and be naturally cleaned. Sediment particles that contain contaminates settle to the bottom so the water that flows out is clean. Ponds can host a variety of plants, can contain fish, and create a comfortable space in the landscape.
Retention ponds can have a permeable bottom so water can filter into groundwater, or they can have an impermeable liner. Water flows in from the source and stays in the pond until it is full or is drained. Ponds are usually deeper than three feet so the water can stay cool, in order to avoid algae growth. Once the water is drained or overflowing, it flows out of the pond and into waterways, cleaner than before.
OK, call it what you want - but it has been built and designed to hold water in the front yard - Heavy daily afternoon rains are prevalent and this area is likely to hold water for extended periods during the summer - How about a hazard for small children?
It appears to be a retention pond that is common in Florida as a means of “recharging” the ground water supply. Quite often it’s a requirement in the early entitlement process and is reflective of the developments overall master plan. Think “sink holes”.
A retention pond is designed to hold a specific amount of water indefinitely. Usually the pond is designed to have drainage leading to another location when the water level gets above the pond capacity, but still maintains a certain capacity.
A detention pond is a low lying area that is designed to temporarily hold a set amount of water while slowly draining to another location. They are more or less around for flood control when large amounts of rain could cause flash flooding if not dealt with properly.
