This site is located at the corner of Azie Morton Road and Lund Street. It is located on a very steep slope so typical erosion controls are not adequate, and in significant rainfall events, the erosion controls as currently installed are fail to function. The tridiagonal dikes are often haphazardly placed and have gaps at the ends or underneath them allowing runoff to easily pass under or around them. Even when they are flat on the concrete apron, they allow muddy runoff to flow under them. These tridiagonal dikes are simply unable to control runoff from a site this steep. Runoff from this site flows down Azie Morton on the southeastern side and then crosses over the road to the northwestern side. It then flows to the entrance of the little league base baseball field, crosses the parking lot, and empties into Barton Creek below Barton Springs Pool near the Sunken Gardens. In virtually every rainfall event, there is muddy runoff leaving this site and flowing down to Barton Creek. This site has been reported to the City on mulitple occasions, and additional controls are needed to prevent runoff from this site. However, the City has repeatedly failed to address the issue.
The video and photo were taken during or shortly after a 1.76" rainfall event (as measured in the neighborhood) that lasted for about an hour and a half. The video starts on Azie Morton where the muddy runoff turns into the little league baseball field parking lot and flows to Barton Creek. The muddy flow is followed upstream to its source at 809 Azie Morton. About halfway, the muddy flow crosses Azie Morton from the southeastern side to the northwestern side. At the site, although some controls are in place, muddy runoff is pouring through and under the triangular dikes to the street (blocked from view in the video by a vehicle).
The video starts on Azie Morton at the turn into the little league baseball field and follows the muddy flow upstream to its source at 809 Azie Morton. About halfway, the muddy flow crosses Azie Morton from the southeastern side to the northwestern side. At the site, muddy water is flowing between the triangular dike and mulch sock.
The video starts on Azie Morton a little past the turn into the little league baseball field and follows the muddy flow upstream to its source at 809 Azie Morton. About halfway, the muddy flow crosses Azie Morton from the southeastern side to the northwestern side. At the site, muddy water is flowing through a rip in the triangular dike.
The silt fence is in worse shape than previous event.
The silt fence is mangled and ineffective. The excavation has cut away the soil resulting in significant walls/cliffs that currently have no structural bracing. In significant rain events, these wall faces could collapse and release significant amounts of sediment, not to mention the possibility of the house above being affected.
The silt fence in Photo 1 is crumbled and will allow sediment to escape if it rains. Note the large piles of dirt to the left. The backside of these dirt piles are visible through the trees in Photo 2. There are no ersosion controls on the backside and sediment from these dirt piles can escape.
This is the aftermath of a discharge event. Prior to these photos, significant amounts of muddy water were being discharged by a contractor to the roadside along Azie Morton Road. The water flowed down the southside of the road, crossed over to the north side of the road, and then into Little Zilker Creek and Barton Creek. These photos were taken well after the discharge but show the puddles that remained.
There are no erosion controls in place below where all of the soil disturbance is taking place.
