Title
Consider and take action on a resolution authorizing a professional services agreement with RPS Group for design work related to the Jarbo Bayou Watershed Drainage Study (DR2308B) in an amount not to exceed $126,890 (Executive Director of Development Services)
Background:
Approval of this resolution will authorize the City Manager to enter into an agreement with RPS Group (RPS) for a drainage study in the Jarbo Bayou Watershed in an amount not to exceed $126,890.
The area for the Jarbo Bayou Watershed drainage study is limited to Jarbo Bayou to the north, Lawrence Rd to the east, Woodcock St at the south and Columbia Memorial Parkway at the west.

1. Project Management & Coordination - this category includes general project management, such as schedule, coordination meetings, quality control, monthly status report.
2. Data Collection - this category includes data collection by using available LiDAR, GIS data, and plan of record drawings of the area (As-Builts), conducting one field visit, identify major outfall to Jarbo Bayou and League City Parkway
3. Topographic Survey - RPS will determine specific topographic survey needs of the follow but not limited key drainage infrastructure such cross section, flowline and size of culvert and ditches, bridge geometry and flowlines, spot check for roadway centerline.
4. Modelling and Analysis - this category will evaluate existing models to determine the existing flooding, create a ROM -2D mode...
