FM 149 Neighborhood Phase 2 — Phased Development Civil Engineering in Anderson, TX
Anderson · Grimes County · Texas
Residential & Multifamily Development
Extending an approved drainage framework into a second phase
JRH Engineering provided complete civil engineering design for Phase 2 of the FM 149 neighborhood in Anderson, Texas, building on the drainage infrastructure, approvals, and agency relationships established in Phase 1. Phase 2 moved faster — permits were accelerated by leveraging the approved and constructed framework already in place, and the hard infrastructure and approval work did not need to be repeated.
AT A GLANCE
Site civil design
Full civil design for Phase 2 lot development and road extension
Phase 2 road and drainage tied into the approved Phase 1 infrastructure — no redesign of the base drainage or access framework
100-year overflow path along existing Phase 1 roadways used for Phase 2 drainage — eliminating the need for additional major drainage infrastructure
Stormwater and drainage
Existing 100-year overflow routing established in Phase 1 extended to serve Phase 2 — no new major drainage channels or structures required
Phase 2 detention tied into the Phase 1 system — an integrated drainage approach across the full 140-acre development
Permitting and agency coordination
Anderson County and TxDOT Phase 2 approvals accelerated by prior relationship and approved Phase 1 infrastructure
Phase 2 permit package simpler than Phase 1 — existing approvals referenced, existing infrastructure credited
The Challenge — why Phase 2 moved faster than Phase 1
Phase 2 permitting moved faster than Phase 1 because the hard work was already done. The infrastructure investment, the agency relationships, and the approved drainage framework from Phase 1 all carried forward — compressing the Phase 2 schedule and reducing the engineering and permitting scope.
JRH’s Approach
Rather than start Phase 2 as a new design problem, JRH extended the framework Phase 1 had already put in the ground. The 100-year overflow path along the existing Phase 1 roadways was carried into Phase 2, and Phase 2 detention was tied into the Phase 1 system as one integrated drainage approach across the full 140-acre development. The permit package referenced the existing approvals and credited the constructed infrastructure, so county and TxDOT review moved on a shorter path than Phase 1 had taken.
The Results
01
Phase 2 permitting accelerated by leveraging Phase 1 approved infrastructure and agency relationships
02
No new major drainage infrastructure required — the 100-year overflow path along Phase 1 roads was extended to serve Phase 2
03
Phased development approach demonstrated: infrastructure investment in Phase 1 directly reduced Phase 2 cost and schedule
04
Frequently Asked Questions
What made FM 149 Neighborhood Phase 2 move faster than Phase 1?
Because Phase 1 had already established approved drainage infrastructure and agency relationships, Phase 2 could build on that framework instead of designing new major drainage infrastructure from scratch.
What was JRH Engineering's approach to Phase 2?
JRH extended the 100-year overflow path already established along Phase 1's roadways to serve Phase 2, and accelerated Anderson County and TxDOT approvals by referencing the infrastructure and relationships already in place.
What were the results of the FM 149 Neighborhood Phase 2 project?
Phase 2 permitting was accelerated by Phase 1's approved infrastructure, required no new major drainage infrastructure, and demonstrated clear cost and schedule savings from a phased development approach.
