Summary of Roadway Recommendations

• 12-inch Concrete Pavement

• 11’-11’-11’ lanes with 15’ median and 9.5’ pedestrian realm

• 5-feet minimum Sidewalk

• 11’ Left-Turn lanes with 4’ minimum median

• Corner Clips at all intersection

• 660’ minimum median length – (except from Creekbend to Willowbend)

• Full pavement reconstruction to extend 100-ft south of Creekbend

• Full pavement reconstruction at Braeswood southern curb-returns

• Signal Upgrades at Creekbend, Willowbend, Braeswood

• Possible Signal at Dumfries (Pending results from Warrant Study)

Drainage


Drainage - Existing Conditions Northern section located in 100-year Floodplain (Zone AE)

Existing Parallel Systems has one independent Drainage Area (81.4 acres) with 3 Outfalls:

24-inch trunk (10’ East Esmnt); Outfalls into D140-00-00 @ Willowbend

24- to 42-inch trunk (10’ East Esmnt); Outfalls into D140-00-00 @Dumfries

30- to 60-inch trunk (under SB Pvmnt); Outfalls into D100-00-00 @ Braeswood


Outfall @ Willowbend Outfall @ Dumfries

Drainage – Analysis:

Analysis based on latest IDM Chapter 9; TP 100 & TP-101 Criteria

Existing drainage areas delineated using LiDAR data & record drawings

Reviewed existing hydraulic models for 2- & 100-year events using XP-SWMM

Identified flooding areas based on ponding data and flooding complaints

Proposed drainage areas delineated based on full topographic survey andproposed roadway profile and inlet locations

Optimized proposed pipes and inlet sizes for in-line detention to lower the100-yr WSE below MPE

Results of Hydraulic Models

• 2-year HGL below the gutter line

• 100-year WSE are below the MPE


Results of Hydraulic Models:

• Existing outfall (peak flows) have been retained and increase in flowsmitigated within the proposed system


Summary of Recommended Storm Sewer Improvements:

• Utilize existing 2 parallel storm sewer trunk lines, as possible

• Add 3rd storm sewer system ranging from 24- to 42-inch diameter (located alongthe northbound proposed pavement)

• Replacing all existing BB-Inlets / C-inlets to C-1 inlets

• Replace Existing leads / laterals with sizes ranging from 24- to 36-inch diameter


Utilities


Existing Public Utilities:

• 20” water line along the entire project median

• Serves as distribution to 6”, 8” and 16” water lines

• 42” sanitary sewer main with 8”, 14”and 15” service lines


Utility

20” Waterline

42” Sanitary line

Existing Private Utilities:

• CenterPoint Energy electric, street lights

• CenterPoint Gas

• Teppco Crude Pipeline

• Underground Comcast Cable, fiber optic, Level 3, Phonoscope

• AT&T/SWBT 21-4 MCD Duct Bank (along the East ROW)
