When the developer sought approval of their general plan from the City of Houston Planning Commission, the City deferred approval. Instead they asked the developer to consult with the City Engineer and Harris County Flood Control, before coming back to the commission.
Despite the location of the development in the floodplain and floodway of the West Fork, ironically, the City had only procedural comments on the plans. The comments had to do with things like the spacing and labelling of streets. Incredibly, they did not refer to potential flooding or wetlands issues.
Pending Regulation Changes Could Affect Development
Specifically, the County wants the City to change Article III: Standards for Flood Hazard Reduction in the Houston Code of Ordinances, Chapter 19 Floodplain (September 2018):
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.
Where Property Is
Here’s where the property is. It wraps around the Barrington, which was elevated significantly and still flooded during Harvey. It also wraps around River Grove Park Kingwood Country Club, and Deer Ridge Park.
Purple area represents proposed site of Romerica’s Orchard Seeded Ranches Development.
Large Concentration of Forested Wetlands
All aerial photos below were taken on 5/11/2020.

That’s the San Jacinto West Fork cutting through the top of the frame.Looking southeast while hovering over Woodland Hills Drive. The northern part of Romerica’s property lies between the front and back nines of the Kingwood Country Club Lake Course. That’s the Barrington on the right.Those same trees serve as a nesting ground for hundreds of great egrets.Looking southwest from near the entrance from Barrington. Deer Ridge Park wraps around the water tower.Looking SE over Woodland Hills and the Barrington entrance. The property contains three artificial lakes, which I believe were excavated to elevate the Barrington.Note how high lake level/water table is. River Grove soccer fields are on right. Look closely and you can also see the Kingwood Diversion Ditch entering the park from the lower right.
From the ground, beneath the dense canopy of trees, you can see palmettos galore. Palmetto plants are an important biologic indicator of wetlands. They only grow where the ground is underwater at least part of the year.
“Wetlands function as natural sponges that trap and slowly release surface water, rain, … and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage an braking action lowers flood heights and reduces erosion,” says the Agency.
They continue: “Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings. The holding capacity of wetlands helps control floods… Preserving and restoring wetlands together with other water retention can often provide the level of flood control otherwise provided by expensive dredge operations and levees. The bottomland hardwood- riparian wetlands along the Mississippi River once stored at least 60 days of floodwater. Now they store only 12 days because most have been filled or drained.”

All those concerns still exist. Romerica should take a cue from the Humble ISD. They’ve had two ag barns in this area. The District abandoned one (that was actually on Romerica property), moved to higher ground, is trying to abandon the second, and hopes to move to higher ground yet again.

After six months of virtual inactivity, Perry Homes’ new Woodridge Village contractors have significantly stepped up work on three detention ponds. All detention ponds are on the northern section of the development. However, recent heavy rains have saturated the soil. The rain also filled two of the three ponds one-third to one-half full. The result: a big muddy mess.
Tuesday, according to Elm Grove resident Jeff Miller, only one excavator was moving. It was trying to let water out of the N1 pond so that work could continue.
Twelve Aerial Photos Taken on Memorial Day
Below are 12 aerial photos of the site taken on Memorial Day, 5/25/2020.
Looking north along the western boundary of Woodridge at the tail of the N1 Pond.Further north, you can see where work has stopped on the tail of N1 (foreground), the Webb Street Entrance in Porter (left), and the N1 pond itself are at the top.
The N1 pond has the least development. Most work to date has focused on the tail. That’s presumably so contractors can keep the entrance to the site open. N1 will probably be the last pond they finish. And they will probably complete it only after they develop a second entrance to the site off Ford Road (see below).
Only Work Tuesday Was Trying To Drain N1
Looking south along the western boundary from over N1, you can see where the tail ends. The tiny trench letting water out of the tail slows down water. It will eventually be replaced by the four-foot culverts you see on the left.
That tiny trench is where the excavator was working today.
Site Holds More Water than N2 Detention Pond
Still looking south, but further down the western boundary, we can see the old and new portions of the N2 detention pond. It is not currently holding much water because contractors have already opened up the sides. That allows water to escape into Taylor Gully (top center).
Note how there’s more water on the site than in N2.Closer shot shows how workers opened up N2 to Taylor Gully (left of top center). They also continue to widen and deepen the pond toward the upper right corner.Rotating about 90 degrees, we can see how saturated the soil is. The northern portion of the site contains an amazing amount of standing water that isn’t yet able to reach the detention ponds.
The northern portion of the site is roughly 200 acres. Assuming an average of three inches of standing water (one quarter foot), that means the northern portion may contain 50 acre-feet of standing water!
Taylor Gully Did Not Appear to Overflow
Looking southeast at North Kingwood Forest (left) and Elm Grove Village (right), areas where hundreds of homes flooded twice last year.A closer shot shows where water in Taylor Gully, when high, is forced to make multiple turns within a few hundred yards to bypass a 3 foot pipe that connects the channel on either side of the county line. Luckily, water did not reach the overflow spillway from the concrete-lined channel during recent heavy rains, according to Jeff Miller.
N3 Pond Greatly Reduced Flow in Taylor Gully
The pond below (N3) sits directly above the portion of Taylor Gully that flooded Elm Grove and North Kingwood Forest twice last year. The vast majority of this excavation took place earlier this month.
Rotating to the northeast, you can see the N3 detention pond, now mostly excavated. Miller estimates it’s still one half to one third full. Traveling up the eastern side of Woodridge, we can see tremendous erosion along the banks of N3. Those parallel stripes running down the sides of the pond are called rilling, shallow channels cut in the surface of soil by running water.
Simply Excavating Ponds Does Not Mean They Are Complete
Above, you can see that contractors did not yet have backslope interceptor swales in place. Nor did they have the pipes installed to channel intercepted runoff to the detention pond. Accordingly, runoff went over the edges of the pond and washed sediment into it.
The ponds will not be complete until backslope interceptor swales and pipes have been installed and grass planted along the edges of the ponds to prevent future rilling. The ponds also need concrete pilot channels to prevent erosion in the areas of constant use.
New Entrance on East
The new entrance to the subdivision (background below) will be an extension of Mace Street in Porter on the West. It will connect to Ford Road on the East.
Looking straight east from the top of N3. Note two things: a channel designed to funnel standing water to N3 and the new entrance to the subdivision cut into the woods in the distance.
Mace enters the western side of the subdivision just to the left of that silver roof in the distance of the shot below.
Looking directly west across Woodridge Village while hovering over N3 on the eastern border.
There may be a connection between the type of property Perry develops and the problems that customers later develop. If Perry builds on this property, I pity any poor unsuspecting customers who fail to research its history.
No New Statements on Potential County Buyout
To my knowledge, neither Harris County, the City of Houston, nor Perry Homes have issued any public statements about the status of a buyout of this property. Harris County Flood Control District was considering using it to build a regional flood-detention facility. But County Commissioners added new conditions on any buyout in their last meeting.
Twice-flooded residents in Elm Grove and North Kingwood Forest eagerly await new details on the deal. Even if Perry completes work on all the ponds, it will likely not be enough to handle a true hundred-year rainfall event.
Ponds Still Would Not Likely Detain Hundred-Year Rain
Perry rushed to get plans permitted before new Atlas-14 rainfall standards went into effect. They would have required 30% to 40% more detention than the plans that the City and Montgomery County approved.
In the meantime, though, the new detention ponds will greatly reduce the risk of flooding from lesser storms. Also, the National Weather Service has reduced the risk of rain in the next several days. That may give Woodridge Village time to dry out and downstream residents time to catch up on their sleep.

On my most recent flight down the San Jacinto West Fork, I was treated to a rare experience. Just as we flew over US59 heading east, what seemed like a mile-long train started to cross the new Union Pacific rail bridge. As we crossed over the train, the engineer saw me leaning out the door of the helicopter to grab the perfect shot. I think he knew we were documenting progress of the bridge. In salute, or maybe out of pride, he let out a massive blast from his giant air horn. Both the helicopter pilot and I broke out into huge smiles.
A Stirring Moment
It was a stirring moment for someone who has always admired trains. Railroads opened up this country, supported the growth of our cities, and still carry the much of the commerce of our nation on the backs of their rails.
Harvey destroyed the ancient Union Pacific bridge over the West Fork.
Shot taken on March 3, 2018, approximately six months after Harvey. Repairs on the old bridge were still in progress at that point.
First UP had to restore the old bridge to keep traffic flowing.
Then the company had to build a new bridge between the supports of the old bridge.
Finally, once the new supports were in, they had to remove the old ones.
All of that took a little less than a thousand days. And it was fascinating to watch. The result is a tribute to the genius of American engineering and know-how.
Second Major Mitigation Project to Be Completed in Area
This marks the completion of second major flood mitigation project in the Lake Houston Area. The first was TxD0T’s reconstruction of the US59/I69 bridge a few hundred yards to the west. That delayed hundreds of thousands of commuters for 11 months.
The train stretched almost a mile toward Kingwood Drive as it barreled southward. Hopefully, the new bridge may also help reduce train delays at major intersections.
Other Mitigation Projects Still in Development or Being Studied
Other major mitigation projects still in progress or development include:
West Fork dredging to restore conveyance and channel of the river
Additional floodgates for the Lake Houston Dam, to let water out faster
The search for suitable upstream detention to help hold back water during floods
Multiple ditch repairs throughout the area
Drainage studies throughout the San Jacinto River Basin that will undoubtedly lead to additional mitigation projects

Development Watch List: Orchard Seeded Ranches From the Air
The Romerica high-rise project near the floodway of the San Jacinto West Fork was reborn recently as Orchard Seeded Ranches. Same property. Same developer. Undisclosed concept as of this date.
When the developer sought approval of their general plan from the City of Houston Planning Commission, the City deferred approval. Instead they asked the developer to consult with the City Engineer and Harris County Flood Control, before coming back to the commission.
Despite the location of the development in the floodplain and floodway of the West Fork, ironically, the City had only procedural comments on the plans. The comments had to do with things like the spacing and labelling of streets. Incredibly, they did not refer to potential flooding or wetlands issues.
Pending Regulation Changes Could Affect Development
However, regulation changes are pending. Harris County has made adoption of its Atlas-14-based stormwater design and floodplain standards a condition of participating in all flood bond projects. Those standards would require elevation of any homes built on the Romerica property. In practical terms, that means building on stilts. And that, in turn, means dollars.
Specifically, the County wants the City to change Article III: Standards for Flood Hazard Reduction in the Houston Code of Ordinances, Chapter 19 Floodplain (September 2018):
Where Property Is
Here’s where the property is. It wraps around the Barrington, which was elevated significantly and still flooded during Harvey. It also wraps around River Grove Park Kingwood Country Club, and Deer Ridge Park.

Role of Wetlands in Reducing Flooding
The EPA cites flood protection as one of the primary benefits of wetlands.
“Wetlands function as natural sponges that trap and slowly release surface water, rain, … and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage an braking action lowers flood heights and reduces erosion,” says the Agency.
They continue: “Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings. The holding capacity of wetlands helps control floods… Preserving and restoring wetlands together with other water retention can often provide the level of flood control otherwise provided by expensive dredge operations and levees. The bottomland hardwood- riparian wetlands along the Mississippi River once stored at least 60 days of floodwater. Now they store only 12 days because most have been filled or drained.”
Reasons Romerica Application Previously Withdrawn
Last year, when Romerica tried to develop this area as condos and high rises, they ran into protests from US Fish and Wildlife Service, the Army Corps, environmental groups, and the Kingwood community. Major concerns included the filling of wetlands, nesting bald eagles, river migration, flood dangers to residents, and lack of evacuation routes.
All those concerns still exist. Romerica should take a cue from the Humble ISD. They’ve had two ag barns in this area. The District abandoned one (that was actually on Romerica property), moved to higher ground, is trying to abandon the second, and hopes to move to higher ground yet again.
As of this writing, Romerica has not yet reapplied to the City Planning Commission. Nor has the City adopted all of the County’s Atlas-14 regulations.

Why You Don’t Build On Wetlands
The last image above shows why you don’t buy homes built over wetlands, even if the Army Corps ruled that the wetlands weren’t jurisdictional. Any homes built here would likely have foundation problems from shifting soils. Of course, by then, the builder would be long gone.
In reviewing the complaints lodged with the Better Business Bureau against Perry Homes, most of them had to do with failure to honor warranties. Digging deeper, you can see many of the underlying complaints had to do with drainage, flooding, mold, and mildew.
