LWI Region 3 Modeling Overview

3.4 SURVEY PLANNING Survey planning, structure analysis, and automation tools, survey incorporation. 3.4.1 LWI Region 3 Survey Scope and Methodology OVERVIEW { Surveys were conducted in Region 3 along priority streams, targeting bridges, culverts, weirs, dams, levee outlets, and control structures. { Cross-sections were collected to determine stream gradients and adjust LiDAR in areas with standing water for accurate channel representation. DATA COLLECTION { Key survey locations included stream confluences and tops of detailed stream sections to support hydraulic model interpolation.

PLANNING AND FORMATS { WSP developed survey guidance and provided spatial files (ESRI and KMZ) identifying structure and cross section locations. { KMZ files include: • Point file: structure points with required data, such as road profile and upstream face. • Line file: cross section lines to be surveyed bank-to bank. { Deliverables include text files (NAVD88 elevations, Point ID, Structure ID), MicroStation drawings, geo tagged photos, and shapefiles.

{ Pump stations were modeled using data from USACE and local engineers (via City of Monroe manuals) (Figure 3-12).
