YMCA subdivision
The 4.80-acre parcel boundary from the 1988 subdivision plat is outlined in pink.
Read the map
The conflict map compares the YMCA's 1988 subdivision boundary with survey locations analyzed by William O'Hara in 1999. The yellow area is the land Joe Riddell identifies as both claimed by the YMCA and part of Sand Beach Reserve.

The 4.80-acre parcel boundary from the 1988 subdivision plat is outlined in pink.
Yellow marks land that Riddell's map places inside both the YMCA claim and the Reserve.
The green dashed line is O'Hara's Location #2, measured from the bluff shown on the 1885 plat.
What the lines mean
The 1848 patent for Outlot 11 called for its south boundary to lie 60 yards—180 feet—below the bluff. Location #2 applies that distance to the bluff shown on the 1885 Raymond Plateau plat.
O'Hara's other recommended line honors the patent's call for 60 acres. It moves north as it crosses the YMCA parcel and would produce a larger overlap.
Metcalfe's 1916 line is the boundary used for the YMCA's south claim. O'Hara concluded it was in the wrong position.
Why the line matters
“The Grant hereby made to the City of Austin is made for public purposes and in the event of sale by the City of Austin, of the property herein granted, all parts thereof so sold shall revert to the State.”Language of the 1945 State grant, reproduced in the supplied chronology and correspondence
The railroad sold the five-acre tract to Austin in 1961. Austin sold it to the Boy Scouts in 1963, and the Boy Scouts sold it to the YMCA in 1967.
Riddell's conclusion: if Reserve land was inside the 1963 conveyance, that portion reverted to Texas at the moment of sale and could not pass into later private ownership.
The 1963 deed establishes the City's conveyance. The boundary placement and legal consequence are the analysis at issue. This site attributes that conclusion rather than presenting it as an adjudicated fact.
The clearest next step
Put the full survey record online.
The 1999 O'Hara report and its complete exhibits are central to evaluating the boundary but are not yet among the supplied files. The archive should add them, along with the 1848 patent, 1885 plat, 1945 grant, 1961 deed, 1967 deed, and 1988 subdivision plat.
