• In the 1990s, Austin buys all the land from the Veloway to Hays County, from MoPac to Shady Hollow for water protection land to compensate for the huge Circle C development built over the aquifer.

• As a result, Shady Hollow has a half-dozen streets that dead-end on the west. Several of those streets were to be feeder roads to MoPac or SH 45 SW.

• Bailey Middle School is landlocked by these dead-end streets, endangering students.

• SOS unsuccessfully fought MoPac over Barton Creek, although they are supporting a bicycle bridge in the same place today. They also failed to halt expansion of MoPac, first to Slaughter Lane and then to SH 45 S.

• SOS focuses on SH 45 SW as their raison d'etre. Its "Keep MoPac Local" campaign is intended to pit neighbor against neighbor.

• Zoning by road construction does not, and never did, thwart development. It has and is occurring with or without major roads. Austin annexes area south of Shady Hollow to FM 1626 and approves subdivisions with hundreds of home construction permits in this area, adding thousands of vehicle trips per day.

• FM 1626 is undergoing construction, from two lanes to four from Kyle to Brodie Lane. New home development already is under construction, as well as commercial development near Bliss Spillar Road and FM 1626.

SH 45 SW should be an icon for excellence in environmental engineering, not an icon for out-of-touch "environmentalists."

The preliminary report regarding the 
Brodie Widening Alternative takes this option off the table. And here's why!

White -- MoPac
Blue -- FM 1626

Brodie Widening Alternative – Summary

Brodie Lane expansion was considered as part of the upgrade of existing roadways alternative for the SH 45SW environmental study.  The upgrade of existing roadways alternative would satisfy the purpose and need of the project. However, this alternative was dropped from further consideration because the upgrading of Brodie Lane, Manchaca Road, or Slaughter Lane to a highway facility that would meet the purpose and need would require numerous commercial and residential displacements or impacts to protected lands. Therefore, karst or aquifer recharge features associated with the upgrade of existing roadways alternative were not studied.

Expansion of these roadways to meet the purpose and need would result in numerous residential and commercial impacts.  In order to meet the purpose and need, 300 feet of ROW would be required to accommodate a four-lane highway with frontage roads (needed to maintain local access to cross streets and existing businesses, residences, and other facilities located along these roadways as the facility required to meet the purpose and need would not allow for unlimited access). Table 2.2-1 provides a summary of potential residential relocations and commercial displacements that could be required to accommodate a four-lane highway with frontage roads on any of these corridors, assuming a centerline alternative (in which the ROW is widened 150 feet on either side of the centerline).

In order to expand Brodie and Slaughter Lanes sufficiently to accommodate such a facility, approximately 112 acres of new ROW would be required. Of these 112 acres, 79 would be required to improve Brodie Lane. On Brodie Lane, 66 acres are currently residential development. In addition to the number of residences and businesses counted in Table 2.2-1, the Brodie and Slaughter Lane Alternative would impact the Brodie Wild Water Quality Protection Land at the southwest corner of Slaughter and Brodie Lanes. This alternative would also require the relocation of the Primrose School as well as structures associated with St. Johns Presbyterian Church.

Although residential and commercial relocations could potentially be reduced by shifting the roadway to avoid existing homes and businesses, it would not be possible to totally eliminate all relocations. Because there are reasonable alternatives that would satisfy the purpose and need without any relocations or displacements, this alternative is not considered reasonable and was eliminated from further consideration.
