Background and Discussion:
This project is located in the Greens Bayou watershed near Highway 90 and Beltway 8. The Beaumont Place subdivision consists of mainly roadside ditches and has been subjected to several flooding events with the most recent being Hurricane Harvey (August 2017) and the Tax Day Flood (April 2016). Drainage analysis of the subdivision began in late 2019 as a part of the 2018 Bond program for subdivision drainage improvements. The scope and proposed improvements include roadside ditch regrading, driveway culvert upgrades, expansion of channel along Big Gulch, concrete lined Sulphur Gully channel with reinforced concrete box (RCB) crossing improvements. Improvements also include multiple detention ponds along Big Gulch with an extreme event overflow swale towards the upstream portion of the channel.
The Change in contract request includes new items for the following:
• Lime Treated Subgrade - Added Item No. 95 Lime Treated Subgrade with a quantity of 3500 Square Yards for an additional cost of $70,000.00, added Item No. 96 Lime Treated Subgrade (6%) with a quantity of 80 Tons for an additional cost of $30,000.00, deducted a quantity of 778 Cubic Yards from Item No. 6 Excavation for a credit of $19,450.00, and deducted a quantity of 1611 Square Yards from Item No. 33 Crushed Aggregate Base Course 8-Inches for a credit of $80,550.00 to yield a total net-zero cost. The EOR proposed a lime stabilized pavement subgrade for Flagstaff Ln as recommended in the geotechnical report.
Expected Impact:
This project seeks to reduce flooding and strengthen resiliency in Harris County by assisting in the alleviation of structural flood damage to homes in the Beaumont Place Subdivision.
Alternative Options:
The County could elect to fund the requested task or choose to reject it. However, if not approved, the contractor will not be able to complete the original scope of work.
