Clay:

 

I’m sorry I didn’t get this to you within the hour like I promised when we talked this morning.  I have taken a look at the 2 remaining basins left to inventory and believe that they
can be completed for a budget of $55k.  

 

·         The Low estimate based on a count of the assets shown in the existing Addison SW GIS come out to about $44k.  

·         The High estimate based on a 60% increase in assets compared to the GIS result in about $70k.  

 

Based the effort required to complete the SE Addison and White Rock Creek basins last year, and our progress thus far with the other 3 basins, I believe that $55k is a reasonable estimate
for FY’11-’12 planning purposes.  

 

Please let me know if you have any questions.  Once again, sorry for the delay!
