In Tuesday’s Harris County Commissioners Court meeting, while HCFCD Executive Director Russ Poppe was talking about buyouts, Precinct One Commissioner Rodney Ellis used the opportunity to go off on a rant about the County’s proposal to buy Woodridge Village from Perry Homes. The result: yet another condition added to the purchase.
City Must Now Cover Portion of Construction Cost, Too
The City of Houston now must come up with land or cash for part of the construction costs for any additional detention ponds built on Perry Homes’ property – not just the purchase price.
The actual amount would equal whatever the County contributes. For instance, if developing the property into a regional detention basin costs $20 million, and the county puts in $10 million, the City would need to put in $10 million also. But if either partner can find Federal or State funding to pay for part of the project, that amount would go down. For instance, if the the Feds or State put in 80% then the City and County would each pay 10%.
City must contribute land or cash worth half the purchase price.
City must adopt County’s Atlas-14 provisions. Those would apply to the City’s Extra Territorial Jurisdiction (ETJ) as well as the City itself.
Raddick Predicts City Won’t Meet Conditions
Commissioner Raddick predicted there was no way the City would adopt the Atlas-14 requirements.
He also observed that the County would be forcing the City to commit to an expenditure of an unknown size. And that the City wouldn’t know the size for several months because the County has not yet drawn up plans for improvements.
For Elm Grove residents, this is especially worrisome. That’s because, by law, the City Council must approve every City expenditure over $50,000.
So basically, the County is asking for an unknown commitment. Meanwhile, the City cannot make such a commitment until it knows the exact amount. However, Commissioners did not discuss this dilemma in their debate.
Unanimous Vote to Add Extra Condition
The vote by commissioners on the three conditions was unanimous. The motion carried 5-0.
This hill becomes steeper to climb every week.
Perry Site Quiet for Last Two Days
Meanwhile, Jeff Miller reported today that no dump trucks were moving on the Perry Homes’ site. That may have been due to the rains last weekend that are still filling at least the one detention pond and likely filling the others too.
Video of the Commissioners Court meeting won’t be posted until tomorrow. I will link the relevant sections when video becomes available.

The second district makes an arc around the north and west sides of Houston. So expect the discussion to cover more than just the Lake Houston area. Likely topics will include (but by no means are limited to):
Additional flood gates for Lake Houston
Addicks Reservoir
Houston Ship Channel
White Oak Bayou
Other local projects with shared Federal funding.
Attendees can ask questions online. Organizers have committed most of the time to answering those questions. The discussion should last 45 minutes, and in no case will exceed an hour.

Through a Freedom of Information Act (FOIA) request, ReduceFlooding.com has obtained details of Harris County’s request to the City of Houston to revise its flood regs. Complying with the request is one of two conditions the City must meet before the County will purchase Perry Homes’ Woodridge Village.
First, the County wanted the cash-poor City to pay for half the purchase through the donation of land that the County could then use to help offset costs for other HCFCD projects.
Second, the County wanted the City update to its stormwater and floodplain ordinances to make them consistent with the County’s.
Harmonizing the regulations would provide consistency between the three largest governmental agencies tasked with drainage projects in the our area: Harris County Engineering Department, Harris County Flood Control, and the City of Houston.
This is the first step in getting all municipalities and County governments that drain to Harris County to adopt similar standards to help reduce flooding risks and protect the billions of dollars of drainage infrastructure investments currently being made in the area.
A Houston Chronicle article (that didn’t even mention Elm Grove) said, that in the future, the county would not share flood bond money with any of 34 different municipalities within its jurisdiction that have not updated and harmonized their regulations with Harris County’s.
So what were the requested changes?
Below are revisions needed for the City of Houston to comply with Harris County Infrastructure Regulations (2019 version) and the HCFCD Policy, Criteria and Procedures Manual.
In all cases cited below, Harris County flood regulations exceed the City of Houston’s. The County does not ask the City to relax any guidelines.
Houston Chapter 9 (Stormwater Design Requirements – July 2019)
General Note – The City updated this Chapter in late 2019 to add Atlas 14 rainfall information for use in storm sewer design. The County also added Atlas 14 to its regulations.
However, the County requests that the City make additional changes as follows:
Section 9.2 Design Requirements:
9.2.01(B)(3)(a)(1) Table of Rational Method Runoff Coefficients – Must be updated for lots greater than ¼ acre to be consistent with Harris County requirements.
9.2.01(C)(7)(d) Table 9-2 – Revise inlet capacities for Type A, D, D-1, C-2, C-2A, D, D-1, and E inlets to be consistent with Harris County requirements.
9.2.01(D)(3)(c) Relationship of Structures to Street – Revise finished slab elevation criteria to be consistent with Harris County requirements of 18” above the 100-year floodplain, one foot above the maximum ponding depth within a 10’ radius of the structure or at or above the 500-year floodplain, whichever is higher.
9.2.01(H)(2)(d) Waiver of Detention Requirements – Remove this section; it would allow developments to be constructed without detention.
9.2.01(H)(3)(a-e) Calculation of Detention Volume – Revise to remove detention rates based on tract size, revise detention rates to be consistent with Harris County requirements of 0.75 acre-feet/acre for storm sewer outfalls and 1.0 acre-feet/acre for roadside ditch outfalls, or HCFCD requirements if outfalling to HCFCD facility.
9.2.01(H)(3)(a-e) Tracts >50 acres – Refer to HCFCD requirements if outfalling to HCFCD facility, otherwise refer to Harris County requirements if outfalling to storm sewer or roadside ditch.
9.2.01(H)(4) Calculation of Outlet Size – Revise to be consistent with Harris County requirements, remove minimum restrictor size, remove allowable discharge rates of 0.5 cfs and 2.0 cfs per acre and include calculated allowable rates.
9.2.01(H)(5)(a) Private Facilities – Include Harris County pumped detention information including detention rate, allowable drain times, and percentage that must be drained by gravity. Add minimum bottom slopes and pilot channel slopes from Harris County requirements.
Houston Code of Ordinances, Chapter 19 Floodplain (September 2018)
Under Article III: Standards for Flood Hazard Reduction:
19-33(a) Base Flood Elevation Requirements –Must also include a provision that no fill will be allowed to elevate structures proposed for the 100-year floodplain. These structures must be on open foundations designed by a structural engineer.
19-33(c) AO Zones –Revise to require finish floor elevation of three feet above the depth number noted in the specific zone, or 6 feet if no depth number is specified.
19-34(a)(4) –Remove this item that allows fill to be placed in the 0.2% floodplain without mitigating excavation.
19-34(d) Critical Facilities –Add requirement for these facilities to have the lowest floor elevated 24” above the crown of the adjacent street if that is higher than 3’ above the 0.2% elevation.
19-43 (c)&(d) Floodways – Require an engineering report for the foundation in addition to the “no-rise” analysis and mitigation requirements. Add Harris County requirements for foundation design.
19-43(e) Bridges – Add requirement that all bridge construction that modifies the base flood elevation or that modifies the geometry of the bridge or channel must submit a CLOMR and LOMR.
19-75 Manufactured home placement in a floodway or coastal high hazard area – Remove this section that allows for manufactured homes to be placed in these areas.
The County also recommends that the Harris County Floodplain Administratorshould reviewChapter 19 for additional changes to ensure consistency with Harris County floodplain regulations.
Negotiations Still Reportedly Ongoing
City of Houston did not discuss conditions of the Perry purchase in last week’s City Council session. Neither are County Commissioners scheduled to discuss them this week. However, negotiations with Perry are reportedly continuing despite the passage of Perry’s extended deadline.
Meanwhile, with hurricane season less than two weeks away, Perry Homes’ new contractors continue to put the full-court press on construction of detention ponds. They have made more progress in two months than the previous contractors did in two years.

Flood Regs: What County Wants City to Do as Part of Woodridge Village Purchase Deal
Through a Freedom of Information Act (FOIA) request, ReduceFlooding.com has obtained details of Harris County’s request to the City of Houston to revise its flood regs. Complying with the request is one of two conditions the City must meet before the County will purchase Perry Homes’ Woodridge Village.
Background
Woodridge Village twice contributed to flooding in Elm Grove and North Kingwood Forest last year. Ever since, flood-weary residents have pled with Harris County and City of Houston officials to buy the property and build regional floodwater-detention facilities there that would protect them. The City initially declined. The County agreed, but with two conditions.
Harmonizing the regulations would provide consistency between the three largest governmental agencies tasked with drainage projects in the our area: Harris County Engineering Department, Harris County Flood Control, and the City of Houston.
A Houston Chronicle article (that didn’t even mention Elm Grove) said, that in the future, the county would not share flood bond money with any of 34 different municipalities within its jurisdiction that have not updated and harmonized their regulations with Harris County’s.
