Proposed Site Analysis: Pollution problem

  
    Hollenbeck Park’s lake has a 4.3 acre manmade body of water. Which the park is a rare green space that serves the Los angeles community. With a history of water quality concerns due to nutrients and sediment laoding. In the 1950s, the Golden State Freeway was built against its western boundary. The freeway has brought allot of pollution runoff into the lake causing fish in lake to die. making lake hazardous to swim in as well and go fishing like it used to be for many years. There is also an extensive erosion around the perimeter of the lake, which one can notice along the vegitated areas along the walkways.
      The city is looking into few strategies to help rehabilitate the lake, by getting rid of the polluted water from lake and filtering it, They want to stop the freeway water runoff from running into the lake. Currently the lakes edge connecting it to the paved walkway is rocks which does stop a little of the runnoff but it is still able to filter its way into the lake. however the cause of the erosion along the perimeter walkways, compromising the visitors safety. There is alot of algae build up in the lake for this reason. The combination of oil gass from cars on the interstate running into the lake by the rains has damaged the beautiful image and connection that the park has to the community with the lake. where people are only aloud to picnic and visit the park but not engage with the lake completely.
Few things that are being studied for improvements by the city are

  • Replace drinking and potable water now used to refill the 4.3-acre lake and irrigate surrounding park with recycled water, storm runoff and water diverted from the L.A. River.

  • Install an underwater pump to filter and disinfect the water used to refill the lake and irrigate the park.

  • Add more floating wetlands and build a narrow band of wetlands along the shoreline to help filter and clean the water.

  • Install a new liner on the lakebed to reduce seepage and algae.

  • Abandon a sewer pipe that runs underneath the lake and build a new one that circles around the park.


   
In my design I am proposing to do few of what the city is requesting but with few additions to the design.

  • Replace drinking and potable water used to refill the 4.3-acre lake and irrigate surrounding park with recycled water.

  • Install an underwater pump connecting to a bridge waterfall system to filter and disinfect the water used to refill the lake and irrigate the park.

  • build a narrow band of wetlands along the shoreline to help filter and clean the water.

  • Install a new liner on the lakebed to reduce seepage and algae.

  • Abandon a sewer pipe that runs underneath the lake and build a new one that circles around the park.

  • incorporate a Plankton/Algae facade that helps with the pollution filtration of system with the advantage of providing energy to building.

  • Incorporate a smog catchment system that filters out the fog from the air.
