Council,e_b_r Apt had the following q estions regarding the Waterglen Project.
WHAT FLOCDPLI�_11: OR STORE D?A.INAGE MEASURES HILL WhTERGLEII BE EMPLOYING TO
141_TIGATE THE STORM D?AI1tAGE C0110ERNS?
The ;Iaterglen project is more complicated than Hickory Park when you consider
floodplain i-:plications. I4aterglen is impacted by floodfloias from Boy: Elder
Creel_ that cross I-25,and from drainage flows from the north. Waterglen will
be using a number of measures to address these flows. A ;berm will be used
to direct flows to desired locations. Fill will be us,osd to elevate areas
above water surface elevations. Channels will be used to convey flows
to designated outlets. A box culvert will be installed under Vine.Drive
to pass flows under the street. Combination detention and *.pater quality
ponds will be installed to store and clean water generated on site. All
of these measures will comply with current criteria.
?dHAT IS THE APPROXIMATE COST?
The costs for the measures that I identified above are related to the sites
development. There is no cost sharing from Stormwater for these measures.
I talked to the developer's engineer for the cost estimate. There apparently
isn't a clear cost seperation for some of the measures listed above. Some
of these appear to meet dual purposes. For exanple, the berm. along I-25 not
only directs flood flows but also provides a sound barrier from the interstate.
The fill elevates the property above the *cater surface but also provides
enoug:. height for sewer service. The developer's engineer promised to get
back to Yee on their estimated costs and hasn't at the time of this message.
As soon as I get this information I will forward it to you. I wanted to
get the above to you as soon as I could.
If you have any r-Tuestions on the above please let me Know.
