I agree, but I have often found that area to be waterlogged or muddy.
That creek is no wider than Hogan's Creek and the way the landscape is sloped, you get water from both sides. I'd leave it alone, let nature take its course, rather than the City come in and try and improve it, there are already JEA tanks on the south end of Boone Park, and if the City really thought they could do something, it would have been done under Overton's reign. What muddiness? It has not rained in weeks, I'd say its OK to go there now.
I've lived here since 1999, if I was concerned about screaching tires or drunks throwing up in the right of way, or trash in the median from the inconsiderates (they know who they are), or the dog crap that owners leave in yards, I would have just moved to the Southside where there are so called "rational" families. I'm here for the long haul, but god forbid someone gets killed from the growth, it will all hit the fan. So with growth, comes more responsibilities, and the merchants know that growth comes with a cost, a real one for more police presence.
