Narrative:

VFR flight in local area, as many times before. Overflew sgr at 1200 ft AGL (actually 3 NM west) as many times before. Using LORAN to stay out of class B airspace and houston current VFR terminal for dead reckoning. Later, talking with friends, I was told sgr has a tower, ie, class D airspace. The current houston VFR terminal does not show class D -- (chart title, example of D 'kdwh' and depiction of sgr included). Note class D very prominent at dwh including altitudes and frequencys -- nothing over sgr. FSS NOTAMS for flight between dwh and efo did not include description of added airspace! I was fully prepared -- current chart, current NOTAMS, and familiar with area -- lived there 18 yrs. If I was this prepared and didn't know, how would anyone else know sgr is now class D airspace? Callback conversation with reporter revealed the following information: airport manager stated a control tower was commissioned at sgr the later part of june. NOTAM was issued. Airspace designation by FAA is class G airspace. Information about control tower was not submitted in a timely manner so as to be included in the airport facility directory for july or the sectional charts. Information about tower was published in september airport facility directory and NOTAM was canceled. Manager stated it would take 2 yrs to get airspace designated class D airspace.
