A new GNSS survey for Harris, Galveston, and surrounding counties will begin this October with anticipated deliverables to be completed by the first quarter of 2023.
With this survey, we are excited to achieve the following goals:
1. Obtain 2022 elevations for historical benchmarks that have been surveyed by the District in 1978, 1987, 1995, 2000, and some in 2007.
2. Validate benchmarks within the NGS database for community use.
3. Provide additional data to verify projections performed in the JRPR PRESS assessment.
