Windcrest Vote NO on 7-11 Street Bond

  The proposed Street Bond for $7.4 Million will total $11 Million over the 20 years.  That's nearly $4 Million in Interest that could be used for Streets.  Couple that with the FACT only Seven (7) Streets are in the proposal.   About 2006 Windcrest approved an Interest and Sinking Fund to pay for street repairs, which included ALL streets in Windcrest.  All streets except major arteries received Slurry Seal (also called Chip Seal) and the main street received overlay.  

Below are the 7 streets identified in the report with the projected cost of $7.4 Million, that will cost , $11 Million, over 20 Years.  Note: some streets get portions of each type of repair.

Balfour            8" Mill/Overlay, 3" Mill/Overlay and Slurry Seal.
Crestway         3" Mill/Overlay
Eagle Crest     8" Mill/Overlay
Fenwick          8" Mill/Overlay,   3" Mill/Overlay, Slurry Seal,
Midcrown       8" Mill/Overlay    3" Mill/Overlay
Windsor Hill   3" Mill/Overlay and Slurry Seal

   This is the Engineers report.

Base Failure Repair 

Removal of any distressed areas where the pavement is fractured and broken and is allowing water to

weaken the subgrade under the roadway and afterwards new asphalt and base materials are added. Repair

is normally made to a depth of 12 inches. These repairs are accomplished prior to the scheduled resurfacing.

Crack Sealing

Liquid asphaltic materials are injected (sprayed) into street cracks to prevent water intrusion.

Geogrid

Geogrids are geosynthetic material made from polymers such as polypropylene, polyethylene or polyester

and are used widely in Civil Engineering applications to provide tensile reinforcement of soil. Essentially

geogrid is a synthetic underlayer added to the roadway before new materials are installed.

Milling

The removal of old roadway materials by grinding the materials to a specified depth and removing the

grindings from the site. Normal milling depth is 2 to 10 inches

Overlay

Overlay involves the placement of a new layer of asphalt, approximately one and a half to three inches

thick, on the street. Properly maintained, an overlay can extend the life of the street by 20-25 years although

heavily used streets may require more frequent overlays

Slurry Seal

A blend of oil and small aggregate that is applied to the streets. Slurry seal is a preventative maintenance

procedure. Slurry sealing can extend the life of a street by 5-7 year
