Close of Season _ 2019

This is meant to share our recent Lake Health Test results and offer their respective meaning to the community.  The factual information can be found under Lake Health tab on this site (see Home Value _ Lake Health, and Aurora Lake Report).     


1) Up to 30% of your property value is associated to the lake,
2) Nitrogen and Phosphorus levels in the lake are at the higher end of the max limit promoted by the EPA,
3) The bottom three feet of our lake has a very low-level, or no-oxygen,
4) 25% + of our lake bed is organic sediment (muck), which contributes to our nitrogen levels, 

5) We have tracked very low bacteria counts this season, and
6) Aurora Lake is utilized as a retention pond for a three-county watershed. 


Why is this important and how does this relate to property value (see Home Value _ Lake Health)?

 

Blue Green Algae events occur when lakes/ponds have high levels of Nitrogen and Phosphorus. If the Blue Green events become continuously visual and toxic, then the recreational value of the lake will decrease. As a result, so does your property value. To be clear, this will impact all the homes in community. This may also impact surrounding businesses (think gas, grocery, insurance, and other). The reality is this is a larger problem for the community to manage as the larger community has created the problem. 


The good news: We have a four-point plan (see Aurora Lake Report)


Resident

1) The community needs you to engage your council person, and respective Mayors regarding Storm Water Treatment Plans in your city, or Village.  Make sure they are in the process of retro-fitting their plans to meet EPA standards.  The reality is that both the City, and Village allow storm water to be directly deposited into the waterways, and lake,
2) The community needs you to do your part by utilizing low-level, or phosphorus free fertilizer. If you have phosphorus in your fertilizer, then seek a slow release product. Minimally, please blow your grass clippings, and fertilizer into your lawns.  Otherwise, the excess material travels to the storm sewers and is routed to our streams, waterways, and lake.  Also, fortify break walls when possible to limit erosion.  Run-off and Erosion are key contributors to both Nitrogen and Phosphorus in the lake.


HOA's:

3) ALA will be working with the HOA's to pursue four water-treatment areas, or forebays at core run-off points (Glenwood Blvd, Sunrise Cove, and two along the North Shore).  The goal is to slow the water before it enters the waterways, or lake and enable the Nitrogen and Phosphorus to settle out, or be absorbed.  Estimated Expense: $1M, and
4) ALA will be working with the HOA's to pursue aeration as a solution with the goal to promote an oxygen rich lake bed. This will also reduce the muck levels over time and should yield an additional 1'-2' depth.  Estimated expense $1M. 


As stated, the ALA is working with both HOA's. Our intent is to also engage Council, The Village, The City of Aurora, and property owners to help mitigate the current, and future risk. The reality is that everyone has something to lose if this is not managed. 


We will be hosting a series of Webinars to discuss the exact details of the studies, and our plans to fix the communities largest and most valuable asset in the coming months. 


There are big projects ahead, and by working together we can fix this ...
