Sierra Club Response to High-Rise Development Proposal in Flood Plain

Below is the Sierra Club response to the Army Corps’ public notice about Romerica’s proposed high-rise development in Kingwood, near River Grove Park.

The proposed high-rise development would go just beyond the tree line in the background. After Harvey, this whole area flooded six times in one year and three times in the last month. In the 80 years before Harvey, it flooded on average once every other year.

A number of people have asked me post responses that people have already sent into the Corps. Feel free to cut and paste sections that capture concerns you have.

Dear Corps and TCEQ,

Enclosed are the comments of the Houston Regional Group of the Sierra Club (Sierra Club) regarding the U.S. Army Corps of Engineers (Corps) Galveston District, Section 10/404 proposed Permit Application No. SWG-2016-00384, Romerica Investments, LLC, located in waters of the United States (U.S.) and wetlands adjacent to the West Fork of the San Jacinto River, Kingwood, Harris County, Texas.  

Point #1 – This proposal will…

  • Fill 42.35 acres of wetlands with 68,323 cubic yards of fill material on 331.45 acres. 
  • Fill 771 linear feet of streams with 285 cubic yards of fill material.
  • Construct a marina/resort district of 107.41 acres and use 19,690.7 cubic yards of fill material to fill 12.21 acres of wetlands; expand an existing 15-acre lake associated with the West Fork of the San Jacinto River to an 80-acre marina with a capacity of 640 boats; construct a new navigation channel south of the proposed marina; expand the existing channel on the east to connect the marina and the West Fork of the San Jacinto River; develop 25 acres north of the marina into a resort district with commercial and residential development; construct five towers with a height of 90 feet for the western hotel area, 260 feet for the residential condominium towers, and 500 feet for the eastern hotel and condominiums; excavate fill material to raise the elevation of the entire resort district from 45 to 57 feet (13 feet total) above base flood elevation of the 100-year floodplain of the West Fork of the San Jacinto River.   
  • Construct a commercial district of 64.41 acres and use 959.6 cubic yards of fill material to fill 0.59 acre of wetlands and 110 linear feet of streams; construct on 47 acres retail, residential, and office developments; construct three towers that range from 230 to 400 feet tall for retail offices and residential condominium towers; construct a 70-foot tall mid-rise residential and retail development; construct parking garages with two below grade levels and concealed above grade levels; expand an existing 16.25-acre lake to a 19.25-acre lake (3 acre expansion) to create a marina for personal watercraft parking; create a 125-foot wide interconnecting channel between the 80-acre marina and 19.25-acre marina to provide access between the two marinas, marina/resort district, and the commercial district; excavate fill material to raise the elevation of the entire resort district from 45 to 57 feet (13 feet total) above base flood elevation of the 100-year floodplain of the West Fork of the San Jacinto River.   
  • Construct a residential district of 136.93 acres and use 46,213.9 cubic yards of fill material to fill 28.60 acres of wetlands and 404 linear feet of streams; construct on 64 acres 65-foot tall condominium structures which are on 58.5-feet tall pier/beam foundations with elevated first floor parking and with four stories that will be above the 100-year floodplain of the West Fork of the San Jacinto River; construct on 6-acres, 25-story condominiums with parking garages; place fill in the southern portion of the residential district to raise the structures and elevations to 57 feet above the 100-year floodplain of the West Fork of the San Jacinto River; construct four lakes for a total of 6.75 acres in the western portion of the residential district; construct 1.95 miles of  41-foot wide roadways within a 60-foot wide right of way in the residential district; construct 4-foot and 8-foot wide trails within a 20-foot wide easement around the perimeter of the residential district and use bridges to cross all streams and channels; relocate the existing utility easements that are in the proposed 20-foot pedestrian trail easement.  
  • Construct a Woodland Hills Road expansion of 22.7 acres and use 1,743 .8 cubic yards of fill material to fill 0.96 acre of wetlands and 257 linear feet of streams; construct Woodland Hills Drive so it is expanded from two to four lanes, has turn lanes, and has a raised median for 1.45 miles, from 0.08 mile south of KIngwood Drive to Hamblen Road.
  • An unknown number of culverts and water quality ponds will be installed.
  • Conduct offsite permittee responsible wetland mitigation or purchase credits from an approved wetland mitigation bank.

Point #2:

Page 2, Project Description, Public Notice,now that Hurricane Harvey has revealed the full impacts of flooding in our area, before approving proposals like this one, which are in the 100-year floodplain/floodway, the Corps should require an analysis, using Harvey and other data, about the flood potential and safety of construction in the floodplain/floodway of the West Fork of the San Jacinto River and its tributaries, including Bens Branch-Frontal Lake Houston Watershed, which flooded during Hurricane Harvey.

Although the full extent of the 100-year floodplain/floodway of the West Fork of the San Jacinto River in the 331.45 acres proposed for residential, commercial, resort, and marina developments is not stated in the Public Notice and Plans, most of the 300 plus acres appear to be within the 100-year floodplain/floodway.  According to the Project Description,all of the Marina/Resort District of 107.41 acres, all of the Commercial District of 64.41 acres, the southern portion (we are not told how large this portion is) of the Residential District of 136.93 acres, and the Woodland Hills Road Expansion of 22.7 acres appear to be in the 100-year floodplain/floodway of the West Fork of the San Jacinto River and will have to be filled a maximum of 13 feet to get above the 100-year floodplain/floodway.

Exhibits 2, Plan Overview and 9, Plan View D1, Plans,clearly show that a floodway goes right through the middle of the southern marina, commercial, hotel, and condominium resort district complex near the West Fork of the San Jacinto River and that there is a HCFCD Unit G103-00-00 drainageway that flows just southwest of the boundary of the proposed developments.  In combination with dredged channels, these conduits for flood water will bring more flood water onto the site and help flood the site.

This development makes no sense because it exists right where Hurricane Harvey created some of the worst flooding in 100-year or greater floodplains/floodways; will fill and displace about 200 acres of 100-year floodplain/floodway which will raise water levels and increase the possibility of flooding for others, both up and downstream; will fill in wetlands that are crucial for soaking up water and reduced flows, velocities, and increased sedimentation of the West Fork of the San Jacinto River in its 100-year floodplain/floodway; is subject to further flooding in the future; and destroys more of the natural beauty, water quality, and wildlife habitat of the West Fork of the San Jacinto River.

The Corps must require that the applicant conduct extensive and detailed hydrology and hydraulic studies of the undeveloped site, the proposed developed site, and their interaction with the West Fork of the San Jacinto River and its tributaries during floods.  At least 35 stream segments and 5 lakes/ponds currently exist on the site which are all potential sources of flooding to the site.  This should include an analysis of how the three channels that will be dredged will affect flooding by acting as conduits for floodwater to the rest of the site.  There is no documentation provided from Harris County Flood Control District or City of Houston about how much detention and drainage mitigation are needed to keep these proposed developments from flooding themselves or others who live up or downstream.  This information is needed so the public can review and comment on its adequacy.

The entire 335.45 acres is perforated with stream segments or lakes/ponds.  According to the Waterbody Impact Table, Updated July 2018, there are at least 5 existing lakes that are on the property and there are at least 35 stream segments. These waterbodies will flood during the climate change induced intense rainfalls that have become common in the Kingwood area.  The site is like swiss cheese and is pock-marked with lakes/ponds, stream segments, and 73 separate wetlands that exist on the 335.45 acres.  The water-holding, slowing down, soaking in, and evaporation capacity of 49 of these wetlands will be directly impacted by either total or partial filling due to this proposal.  Remnants of these wetlands will be less able to deal with floodwaters and will be impacted by operation and maintenance actions and activities that create erosion and sedimentation and reduce their flood mitigation capacity over time.  These issues need to be addressed by the applicant, stated in the Public Notice, modeled by the applicant, and revealed to the public for review and comment.  

Point #3

Page 2, Project Description, Public Notice, the applicant does not provide any documentation about how it will provide for operation and maintenance dredging of the site so that Section 10 navigation will continue over the lifetime of the developments and after floods.  Periodic dredging will be required as flood waters fill the three channels and floodplains/floodways with sediment. Dredge disposal areas will be needed onsite to allow dredge material to be placed in areas where the 100-year floodplain/floodway is not affected.  The Corps should require that the applicant prepare a dredge disposal management plan.  The public should see this plan and review and comment on its adequacy.

A Section 10 navigation analysis should be conducted by the Corps and this analysis should be provided to the public for its review and comment. The applicant should be required to conduct modeling to determine how boat wakes and flooding will affect erosion and sedimentation of lakes, channels, streams, the West Fork of the San Jacinto River, and its 100-year floodplain/floodway.

Operation and maintenance erosion and sedimentation controls should be required in perpetuity.  The applicant states that it will expand the “existing 15-acre lake associated with the West Fork San Jacinto River”.  This indicates that this lake is natural and a part of the West Fork of the San Jacinto River.  This means that at least 15 acres of waters of the U.S. will be altered by this proposal. Mitigation for this alteration should be required along with wetlands and streams mitigation.   

Point #4

Pages 3 and 4, Avoidance and Minimization, Mitigation, and Notes, Public Notice,the Corps should require that the applicant now provide its permittee responsible mitigation plan for wetlands, streams, and waters of the U.S. and or purchase of wetland credits from wetland and stream mitigation bank(s), so the public can review and comment on its adequacy.  Any wetlands or streams left after proposed developments are constructed will be impacted by developments’ actions and activities and the applicant’s operation and maintenance of developments (secondary impacts) like mowing, trampling by people, use of herbicides, use of pesticides, cutting of vegetation, fertilizer use, use of motorized machines (off-road vehicles), wildlife mortality due to cats and dogs, pet fecal material, roadkill, light pollution, noise pollution, oil and fuel spill pollution, littering, trash dumping, mosquito control, bird collisions with buildings, non-native invasive plant species spread, illegal fills or excavations, nonpoint source water pollution from impervious surface run-off, etc.  There must be an analysis of developments’ actions and activities and operation and maintenance impacts and the applicant must prepare and present to the public for its review and comment developments’ actions and activities and operation and maintenance plan that will be implemented after construction.

The Sierra Club visited the site on December 31, 2018 and walked the west perimeter.  The Sierra Club found in many places Dwarf Palmetto, Loblolly Pine, Yaupon Holly, Trumpet Vine, Water Oak, Sweetgum, American Elm, Laurel Oak/Willow Oak, Swamp Chestnut Oak, Japanese Climbing Fern, Greenbriar vine species, Common Persimmon, American Sycamore, Cinnamon Fern, and Bald Cypress along streams and in flatwoods on the site. Much of the site is a Palmetto-Hardwood bottomland forest or a bottomland flatwoods forest.

In the more upland areas (which are needed as “buffer zones” to prevent water quality degradation over the short and long-term of conservation areas, streams, bald cypress sloughs, bottomland hardwood forested wetlands, bottomland flatwood forests, and riparian woodlands) the Sierra Club found Eastern Hophornbeam, Red Bay, Cherry Laurel, Farkleberry, American Beautyberry, Yaupon Holly, and Post Oak. 

It is a concern that the Corps has not verified the Interim Hydrogeomorphic assessment and Level 1 Stream assessment.  This is particularly important since a major river, the West Fork of the San Jacinto River and part of Lake Houston, will be impacted by these developments.  The public should be provided this information so that it can review and comment on its adequacy.  The Corps should either deny the permit application or return it to the applicant until the mitigation plan is prepared and made available for the public to review and comment.  At the very least, the wetlands mitigation for such a proposal should be 10:1 which would mean an over 400 hundred acre permittee responsible wetlands mitigation project or credits from one or more wetland mitigation banks.

There is a total of 73 wetlands on site; 5 lakes/ponds (waterbodies and waters of the U.S.), and 35 stream segments.  Of these wetlands, there are 41 palustrine emergent wetlands (PEM); 29 palustrine forested wetlands (PFO); and 3 palustrine scrub-shrub wetlands (PSS).  This proposal will result in the degradation, partial destruction, or complete destruction of 7 stream segments whose total length is 771 linear feet and fill volume is 285 cubic yards.

Of the 41 PEM that exist on the site, 23 (56.10%) will be totally destroyed and 5 (12.20%) will be partially destroyed; of the 29 PFO that exist on the site, 8 (27.59%) will be totally destroyed and 12 (41.38%) will be partially destroyed; and of the 3 PSS that exist on the site, 2 (66.67%) will be totally destroyed.  The number of wetlands that will be totally destroyed on the site is 33 (45.21% of all wetlands – all PEM + PFO + PSS) and the number of wetlands that will be partially destroyed on the site is 17 (23.29% of all wetlands – all PEM + PFO + PSS).  The wetland flood detention and clean water filtration capacity of the site will be severely damaged by the proposal because 68.50% of all wetlands on the site will either be totally or partially destroyed.

When looked at from an acreage perspective, of the 87.177 total acres of wetlands on the site (Wetland Impact Table), 42.349 acres (48.58%) of all wetland acres on the site will be destroyed.  

The fact that the applicant is unwilling to abide by an “existing 17.59-acre conservation easement” for another Corps permit means that the applicant cannot be trusted to ensure that any promised future mitigation for this proposal will be protected in perpetuity.  The Sierra Club requests that the Corps deny this permit based upon the existence of this conservation easement in perpetuity and or require that the applicant protect the 17.59 acres and conservation easement from any impacts due to the proposed developments.  This includes forgoing any commercial and residential development within or next to this conservation easement so that it is protected in perpetuity (a buffer is needed to protect the conservation easement).  The applicant apparently has not placed an adequate number of acres into the conservation easement (12.19 acres of wetlands and 8.99 acres of upland buffer, or 21.18 acres) because the conservation easement is 3.59 acres short of what was required for the previous permit on the site.

This proposal violates Section 404(b)(1) Guidelines, which are mandatory for the Corps to follow as part of the implementation strategy that the Clean Water Act requires.  Section 404(b)(1) Guidelines require that non-water dependent actions (hotels, access roads, condominiums, residential areas or districts, commercial areas or districts, and resorts) must not be permitted to destroy wetlands which are “special aquatic sites”.

However, that is exactly what this proposal does since it would put all of these uses in jurisdictional palustrine forested wetlands (riparian woodlands and bottomland hardwood wetland forests), palustrine emergent wetlands, and palustrine scrub-shrub wetlands. Practicable alternatives exist including no development in most wetlands which would mean a smaller and less destructive proposal.

This practicable alternative is “available and capable of being done after taking into consideration cost, existing technology and logistics in light of overall project purposes.”  As required by the Section 404(b)(1) Guidelines, “If it is otherwise a practicable alternative an area not presently owned by the applicant which could reasonably be obtained, utilized, expanded or managed in order to fulfill the basic purpose of the proposed activity may be considered”.

There is no documentation in the permit application public notice that shows that the permittee has conducted a study to determine if other sites exist which could be used. As the Corps knows the presumption is that these practicable alternative sites exist in the Section 404(b)(1) Guidelines “unless clearly demonstrated otherwise”.  No such demonstration is evident in the information the Corps sent out with the public notice.  The public must have this information, so it can review, comment.

Point #5

Page 4, Notes, Public Notice,the Corps states that project information has not been verified.  The Sierra Club is concerned about Corps policy that allows the release of public notices with information furnished by the applicant that has not been verified. This puts the public in an untenable situation of not knowing if the information it reviews is valid, complete, and accurate.

The Sierra Club strongly believes that verified project information should be part of all public notices.  Without verified public information the public does not know whether the information that it relies upon to make public comments is accurate and true.  The Corps should change its policy and verify applicant information.  After all, if the Corps, the regulatory agency that issues the permit, does not verify applicant information, then who will?  The public must have this information so that it can review, comment on, and understand all the potential environmental impacts of the proposal.

Point #6

Page 4, Notes, Public Notice,the Sierra Club disagrees with the Corps that an environmental impact statement (EIS) is not needed for this permit application.  The Corps should require a study about the impacts this development will have, direct and indirect (secondary), and provide this information to the public for review and comment as required by the National Environmental Policy Act (NEPA).

An EIS is required due to the permanent, loss of a large acreage of wetlands, the presence of special aquatic sites, possible aquatic resources of national importance (ARNI) that will be destroyed or degraded by the proposal, the construction of the proposal in the 100-year floodplain, and because the proposal enables or induces additional residential and commercial development directly and indirectly in the floodplain which puts people in “harm’s way”.

Some of the ways that this proposal puts people in harm’s way include the expansion of Woodland Hills will destroy existing entranceways to Barrington Kingwood Subdivision at Cotswald Blvd. and Deer Cove Trail Subdivision; destroy an existing sidewalk that goes from the FFA facility in Deer Ridge Park north on Woodland Hills Road; destroy part of River Grove Park and potentially Deer Ridge Park; destroy forests and wetlands on Hamblen Road; connect Hamblen Road to Woodland Hills Road in an area that flooded during Hurricane Harvey; increased traffic and speed of traffic will affect residents, students, and park users and could result in more injuries, deaths, damage to property, and roadkill.  

Point #7

Page 5, National Register of Historic Places, Public Notice,the Corps should give a summary of what the “Intensive Archaeological Survey of the Kingwood Marina Residential District Project, Harris County, Texas”, dated March 2017 and “Intensive Archaeological Survey of the Proposed Kingwood Marina, Harris County, Texas” dated May 2016, found so the public knows about and can review and comment on the summary.

Point #8

Page 5, Threatened and Endangered Species, Public Notice,the Corps should require threatened and endangered species surveys for listed species. The results of these surveys should be reported to the public which should be given the opportunity to review and comment on the results.

Page 3, Current Site Conditions, Public Notice,it is of great concern that the applicant admits there are bald eagles in the project area, but “no nests were found.”  It is not only nests that are a concern for bald eagles.  The habitat of wintering and nesting bald eagles is also of concern.  It is also a concern that disturbance will occur due to these developments in potential bald eagle habitat and may keep bald eagles from nesting in the project area or on the project site.  There must be an adequate bald eagle survey, analysis, and plan conducted and prepared and is available to the public for review and comment.

Point #9

 Page 4, Public Interest Review Factors,the Public Notice is inadequate as the basis for determining the environmental impacts of this proposal and the effect that it will have on the public interest review factors in 33 CFR 320-332, regulatory programs of the Corps, and other pertinent laws, regulations, and executive orders.

Some of the public interest review factors that must be considered and are relevant are conservation, economics, aesthetics, air quality, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, and the needs and general welfare of the people.

The public interest factors analysis is very important and is separate and larger than simply reviewing the proposed dredge/fill impacts and proposed mitigation.  The Corps should prepare its analysis of public interest factors carefully when reviewing this proposal and then provide it for public review and comment.

Point #10

 Page 6, Public Hearing, Public Notice, the Sierra Club requests a public hearing about this permit application and proposal.  The Corps should contact all surrounding businesses, residential areas (like Trailwood Village Subdivision, Kingwood Lakes Village Subdivision, Clubs of Kingwood, Barrington Subdivision, and Kingwood Lakes South Community Association), churches (like Kingwood United Methodist Church), schools, parks (like Deer Ridge Park, River Grove Park, Boy Scout Reserve), and other entities that may be affected by the proposal, up or downstream, so that the local public can find out about, understand, and attend this public hearing and provide public comments.

Conclusion

Due to the concerns raised in this comment letter the Sierra Club requests that the Corps deny this permit application.  The Sierra Club appreciates this opportunity to provide public comment on this proposed permit application.  Thank you.

Sincerely,
Brandt Mannchen

Sand Island Losing Ground to Army Corps

Before

Sand Island South of the Kingwood Country Club’s Island Course. I took this picture from a helicopter shortly after Hurricane Harvey. This giant dune virtually blocks the entire West Fork. Experts think it contributes to repeated flooding upstream since Harvey.

After

Keith Jordan, a resident of Kingwood Lake Estates, sent me the pictures below today. They show how quickly Great Lakes Dredge and Dock and the Army Corps are reducing the giant blockage nicknamed “Sand Island” south of Kingwood Country Club. Keith generously consented to let share his pictures with you. He says that much of the island has already been brought down to the water line. It used to jut up 6-10 feet. Still, much dredging remains to reduce the portion below water and restore the conveyance of the West Fork. Progress may look greater than it actually is at the moment because of persistent flooding. As of this posting, the river is still at 46.07 feet according to the USGS gage at US59. That’s about 3.5 feet above normal.

This booster pump keeps sand moving upstream to placement area #2, an old sand mine on Sorters Road south of Kingwood College.
Dredge #2 from Great Lakes Dredge & Dock has been eating away that Sand Island since moving downstream from River Grove Park.
Much of Sand Island is now at the water level.
This wider shot gives you a good feeling for how little is left.

Hopefully, we will get more recent aerial shots from our local drone pilots soon. As the West Fork returns to its normal level, we will see exactly how much of Sand Island remains.

Guide to Lake Houston Area Floodplain Regulations

Guidelines for floodplain development can bewilder even professionals. Overlapping jurisdictions often have different guidelines.  And guidelines often change, as Houston’s just did. Houston now manages the 100-year and 500-year floodplains differently. Cities also have building codes that include more requirements.


Site of the proposed new marina and high rise development. Shot from over the West Fork shortly after Harvey. Note sand deposited by Harvey. 25 and 50-story high-rises would be built on the narrow strip between the lake and the Barrington at the top of frame.

Overview

People ARE generally allowed to build and place fill in floodplains. However, they must follow local floodplain guidelines and obtain permits that restrict what they can do. They must also submit environmental surveys, mitigate wetlands, and provide hydrologic and hydraulic studies. In Houston, they may move earth from one location to another within a floodplain, but not add to the total volume. The general rule of thumb: zero negative impact on the conveyance of the river.

If a development destroys wetlands, wetland credits must be purchased from a mitigation bank. Mitigation banks place conservation easements on some of our most valuable wetlands. By helping to finance conservation of those areas, destruction of less valuable wetlands elsewhere may be permitted. Generally but not always, the mitigation credits must be within the same watershed. However, this is not always the case. Extenuating circumstances may exist.

KSA once considered placing East End Park in a mitigation bank as a way to help finance its long range parks plan. The conservation easement would ensure that the character of the park never changed. And the money raised would have provided needed improvements to other parks at no cost to residents.

Federal Guidelines and How They Relate to Local

FEMA establishes minimum standards for a community to enroll in the National Flood Insurance Program (NFIP). By enrolling and administering floodplain regulations, it allows their residents the opportunity to purchase Flood Insurance through the NFIP. You must at least build at FEMA’s base flood elevation (BFE). But communities can and do set higher standards. And each may have different guidelines.

Engineers and regulators often talk about “freeboard factors.” Freeboard, a nautical term, means “the height of a ships side between the waterline and the deck.” In a flooding context, freeboard means minimum elevation above the BFE. You often see it described as “BFE + 1 ft.” Or 2 feet. Or X feet. Think of it as a safety margin. Any freeboard above the BFE is considered a local community’s higher standard.

To provide a context, below are links to some of the floodplain management orders/ordinances.

Houston Guidelines

HOW Ordinance is Executed

Note Chapters 9 and 13. They changed on September 1, 2018. Changes address building code issues for FEMA X zones. Zone X includes the 500 year flood plain. Many such areas flooded during Harvey.

Humble Guidelines

Flood Damage Protection Ordinance

Harris County Guidelines for Unincorporated Areas

Main Website

Laws

Cheat Sheet: Quick View of Changes Implemented in January

Montgomery County For Unincorporated Areas

Floodplain

Drainage Manual For Commercial Developments Greater than 15,000 SF 

Army Corps

If a development affects a major waterway like the San Jacinto River, its wetlands, its flow, or endangered wildlife, the Army Corps will also review studies submitted as part of the permitting process. They would look at applications from the point of view of the EPA and Clean Water Act, especially Section 404.  Section 404 of the Clean Water Act (CWA) establishes a program to regulate the discharge of dredged or fill material into waters of the United States, including wetlands. … For most discharges that will have only minimal adverse effects, a general permit may be suitable. This is the major focus of the permitting process now underway for the high-rise development in Kingwood.

TCEQ

The Clean Water Act also contains a section 401.  It specifically focuses on how States and Tribes can use their water quality standards in Section 401 certifications to protect wetlands. States and Tribes can review and approve, condition, or deny any Federal permits or licenses that may result in a discharge to waters of United States within their borders, including wetlands. States and Tribes make their decisions to deny, certify, or condition permits or licenses primarily by ensuring the activity will comply with applicable water quality standards. In addition, States and Tribes look at whether the activity will violate effluent limitations, new source performance standards, toxic pollutants restrictions and other water resource requirements of State or Tribal law.

Jurisdictional Divides

The Houston ordinance only applies to Houston’s jurisdiction. Houston does not influence neighbors and cannot control or force their policies on other jurisdictions. That is important since Kingwood is surrounded by Humble, unincorporated Harris County (Atascocita and Huffman), and unincorporated Montgomery County.

The Key

Understand that if a developer/individual meets the requirements identified in the floodplain ordinance(s), they can develop in the floodplain (including the floodway). Floodplain administrators must follow the law. However, they try to discourage dangerous floodplain development by “working to rule.” By strictly following all rules with no wiggle room, floodplain administrators can drag permitting processes out. A knowledgeable floodplain administrator can find problems with plans, surveys, and engineering reports for years. By requesting revisions, they can make life so difficult for applicants that it affects the economics of their developments. Eventually they may decide that a project falls into that great black box called “too hard to do,” and walk away.

Words of Wisdom

A regulator told me today that the more people who protest a permit, the harder they are to ignore.

If you have concerns about the high rise development in Kingwood, make sure you register them with the Army Corps (which is currently reviewing the permitting from a CWA 404 perspective). The deadline: January 29.

498 Days Since Hurricane Harvey

Army Corps Permit Evaluation Process

The post about the proposed high-rise development in the floodplain/floodway of the San Jacinto River received thousands of views and hundreds of comments. I’ve also received lots of advice including two presentations by concerned residents. The presentations linked below discuss the Corps’ permit evaluation process.

Warning: NOT for the feint of heart. Together they contain more than 300 pages! Frankly, permit evaluation is far more complex than I imagined.

Site of proposed marina after Harvey. Fresh sand deposits reached almost five feet in height. River Grove Park is beyond this, to the right of the giant sand bar which the Army Corps just dredged through. The drainage ditch it blocked drains the western third of Kingwood.

Plea for Expert Advice

I’m publishing the presentations here because thousands of engineers, project managers, and lawyers with technical backgrounds live in the Lake Houston area. With your help, I’m hoping we can sort through the material and determine a productive response to the Corps’ Public Notice.

As you review these, keep in mind what the Corps wants: “…to solicit your comments and information to better enable us to make a reasonable decision on factors affecting the public interest.” The Public Notice goes into great detail about the scope of the project but focuses largely on the environmental impact of introducing “68,323 cubic yards of fill material into 42.35 acres of wetlands and an estimated 285 cubic yards of fill material into 771 linear feet of streams adjacent to the West Fork San Jacinto River.”

Key Elements of Solicitation

Other key points to consider in the Public Notice include:

  • “A preliminary review of this application indicates that an Environmental Impact Statement (EIS) is not required. Since permit assessment is a continuing process, this preliminary determination of EIS requirement will be changed if data or information brought forth in the coordination process is of a significant nature.”
  • They say, “Our evaluation will also follow the guidelines published by the U.S. Environmental Protection Agency pursuant to Section 404 (b)(1) of the Clean Water Act (CWA).”
  • “The TCEQ is reviewing this application under Section 401 of the CWA and in accordance with Title 30, Texas Administrative Code Section 279.1-13 to determine if the work would comply with State water quality standards.”
  • “The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity on the public interest.”
  • They then define the public interest as: “All factors, which may be relevant to the proposal, will be considered: among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs and, in general, the needs and welfare of the people.”

Background Information on Corps’ Permit Evaluation Process

The first presentation sent to me describes the Corps permitting process and requirements to the Society of American Engineers.

The second goes into additional detail about the Corps regulatory program and how they make decisions. They developed it for a TxDOT conference.

I pray that people, their property, and their safety count for as much as birds and fish in this process. However, I’ve talked to several birders lately who are abuzz about eagle spottings near the project site.

Corps Finishing Touch-Up Dredging at River Grove, Moving Downriver

Good news for residents. Last week, the Army Corps of Engineers and its contractor, Great Lakes Dredge and Dock, finished dredging the area up to the boat dock at River Grove Park. However, because of the size of the hydraulic dredge, it could not quite finish the job. So on Monday, the contractor returned with mechanical dredging equipment to work in the tight drainage ditch area by the boat dock. See the photo below courtesy of Don Harbour.

Mechanical dredging equipment was able to maneuver into the tight location that the hydraulic dredge could not. Photo courtesy of Don Harbour, a local resident.

The Kingwood Service Association also requested the Corps to reduce the angle on the edge of the remaining side bar. Young people frequently played on the bar. Community leaders were concerned that a cave in near the steep edge could cause a bad accident.  

Contractors scraped back edge of sand bar to prevent cave-ins caused by curious kids.

As you can see from the edge of the bar in the photo above, the Corps has addressed that issue. 

This afternoon when I visited the park, I saw a survey boat checking to ensure the contractors had reached the proper depth.

Multiple Activities Create Hazards for Recreational Boaters

The River Grove area today was busier than Santa’s workshop on Christmas Eve. However, the main focus of dredging activity will soon move east. Dredge #1, operated by subcontractor Callan Marine is now working close to the West Lake Houston Parkway Bridge. Dredge #2, operated by Great Lakes, is now operating just east of River Grove (see point #4 in photo below).

The river is busy. Stay off it for your own safety.

From the boat dock today, I saw five different clusters of activity in different areas: 1) survey boat, 2) mechanical dredge, 3) debris removal on far side of river, 4) Hydraulic dredge moving towards the country club, and 5) a back hoe removing vegetation from the triangular sand dune  in the distance.

Both dredges will continue to work their way east until they reach their respective goals. 

Latest Schedule

The Corps’ schedule originally called for completion in mid-April 2019. However, crews have been delayed by recent storms and floods, as well as greater than expected sedimentation in the river. Their most recent schedule calls for completion by April 30 and demobilization during the first two weeks of May.

Status of Mouth Bar Project Still Uncertain

Everyone I talk to hopes FEMA and the Corps will grant approval for a second project that addresses the huge sand bar at the mouth of the West Fork before this project reaches completion. If that does not happen, demobilization and remobilization at a future date would cost about $18 million. 

The “Mouth Bar,” a giant sand bar that blocks the West Fork of the San Jacinto, backing the river up into Kingwood and Humble. The mouth bar is not within the scope of the current Army Corps dredging project, but officials have been trying to get FEMA and the Corps to include it. Water depth is generally 1-3 feet around this bar. Max channel depth in places is just 5 feet.

Sources in Austin expected an announcement weeks ago on the mouth bar. Congressman Ted Poe requested a meeting with the head of the Army Corps to discuss the project. However, the  meeting originally scheduled for November 28th was delayed into next year. That means Congressman-elect Dan Crenshaw will inherit the battle. Meanwhile, Senator Ted Cruz has thrown the weight of his office behind the effort to dredge the mouth bar.

Corps to Meet with Super Neighborhood Council Wednesday Night

Eduardo Irigoyen, the project manager of the Emergency West Fork Dredging Project (the dredging currently underway), will meet with the Kingwood Super Neighborhood Council tomorrow night. The meeting at the Kingwood Community Center starts at 7PM. Mr. Irigoyen will update local leaders on the status of the Corps’ project. The meeting is open to the public, but seating is very limited.

Additional Dredging on the Horizon in 2019

Reprinted verbatim from Council Member Dave Martin’s announcement:

The “Mouth Bar,” a giant sand bar that blocks the West Fork of the San Jacinto, backing the river up into Kingwood and Humble. Water depth is generally 1-3 feet around this bar. Max channel depth in places is just 5 feet.

Houston, TX – Council Member Martin would like to make District E residents aware that the City of Houston continues to make progress towards Harvey Recovery with both state and federal agencies. Over the last fifteen months Council Member Martin has been working diligently with Chief Resiliency Officer Stephen Costello, Mayor Sylvester Turner, Governor Abbott, Chief Nim Kidd, as well as the offices of Senator Ted Cruz and Senator John Cornyn towards several initiatives that would have a positive impact on the Lake Houston Area.

Most recently the Texas Water Development Board (TWDB) has completed the bathymetry study of the West Fork of the San Jacinto River for the City of Houston. Data from this study has been given to the Army Corps of Engineers (ACOE) to determine the amount of sediment that resulted from Hurricane Harvey. This information is useful because this study identifies underwater topography allowing the City to understand where the additional sediment brought in by Hurricane Harvey has been deposited in the river and lake as well as changes in depth.

The TWDB continues to survey the entire lake for the Coastal Water Authority (CWA), the agency that contracts with the City for management of the Lake Houston Spillway Dam. The schedule for the TWDB to complete their survey of Lake Houston is Summer 2019. In addition to conducting a bathymetric study the City of Houston is currently reviewing data collected by the ACOE during a recent Light Detection and Ranging (LIDAR) study which uses light in the form of pulsing lasers to measure the distance from the water’s surface to the bottom of the river and lake. Capacity losses due to sedimentation in the lake as well as East and West Forks of the San Jacinto River will be determined using the LIDAR data along with the completed bathymetric study once the TWDB has completed their survey and report.

The LIDAR study allows the City to map changes in shoreline as well as make digital elevation models. It is this data that is assisting the City and ACOE in determining the amount of sediment that needs to be removed from locations along the West Fork of the San Jacinto River like the “mouthbar” that is located just south of the Deerwood Country Club. The LIDAR Study results will also be used by the Harris County Flood Control District (HCFCD) for the creation of new flood insurance rate maps because of the changing rainfall patterns published by the National Oceanic and Atmospheric Administration. The flood insurance map study will utilize updated LIDAR surveys of the entire county and will take several years to complete, however HCFCD is already hiring consultants to assist with this work.

On October 11, 2018, Council Member Martin met with Governor Abbott’s Executive Staff, TDEM, FEMA, and ACOE in Austin where a lengthy discussion was had about the amount of sediment deposit that will still remain in the San Jacinto River after the current emergency dredging project is completed. The current emergency dredging contract is not scheduled to be complete until the end of April 2019. At this meeting the City’s consultant estimated that after the completion of the existing dredging project that there will be approximately 500,000 cubic yards of additional sediment that needs to be removed from the river known in the community as the “mouthbar”.

This estimate however was based on a comparison between the LIDAR study completed by the ACOE this year and a bathymetric study completed by the TWDB in 2011. The important takeaway from this meeting in October is that FEMA agreed that the additional sediment qualifies as Harvey debris however, the estimate of 500,000 cubic yards was not a true amount directly associated with Hurricane Harvey. The City does not have survey data that is immediately pre and post-Harvey which would provide us a true amount of residual sediment that is a direct result of Hurricane Harvey. The City is currently waiting on the ACOE to complete its analysis of the City’s data.

At the meeting in Austin the ACOE indicated that an additional disposal site would be needed in order to remove the additional material. As a result the City of Houston has been proactive in identifying a site, thanks to the assistance of a local landowner that has property on the south side of the West Fork of the San Jacinto. The land owner has retained an environmental consultant to determine any possible wetland issues that may prevent use of the property for disposal. As of right now it appears the property is a viable site and a formal permit was filed with the ACOE this week.

In summary, the process to have the “mouthbar” removed from the West Fork of the San Jacinto River has been an arduous one. All parties from local, state, and federal agencies have been working together to accurately define the area needed for additional removal so that capacity can be restored to the river and reduce the effects of future flooding. The removal of the “mouthbar” cannot begin until the existing emergency dredging along the West Fork of the San Jacinto River is completed. Since this is a reality the City is doing all that it can to be proactive in securing land as well as permits for the “mouthbar’s” removal once the existing project is completed by the ACOE in April. This will allow the ACOE to keep equipment and crews in place without the need for demobilization and remobilization, saving roughly $18 million.

In observance of Thanksgiving the District E office will be closed Thursday, November 21 and Friday, November 22. The District E team will return to the office on Monday, November 26. Council Member Martin would like to wish all District E residents a safe and happy Thanksgiving holiday. For more information regarding this release, please contact Council Member Martin’s office at (832) 393-3008or via email at districte@houstontx.gov.

New Difference Map Confirms Buildup of West Fork Sediment Around Mouth Bar, Underscores Need for Removal

A new “difference map” published by the Texas Water Development Board (TWDB) shows the rapid build up of sediment in the West Fork of the San Jacinto River where it meets Lake Houston. Difference maps show changes in sediment levels over time.

When Stephen Costello, Chief Resiliency Officer for the City of Houston, presented this map at the Kingwood Town Hall Meeting on October 9, it was to describe three potential phases of West Fork dredging..

Having had several days to review and discuss this map, several other things became clear. See the map and legend below.

West Fork Difference Map. Brown/red/orange/yellow/green areas represent decreases in sediment since last survey. Blue, violet, pink and white represent increases.

Conclusion #1:

The worst sediment buildup in the West Fork is near the mouth…exactly where retired Lake-Houston-area  geologists Tim Garfield and RD Kissling said it was when they raised the alarm about the mouth bar month’s ago.

Conclusion #2:

The problem is much worse than even they suspected. This clearly shows the extent of the West Fork’s mouth bar.  Like an iceberg, the part you see above water is only a small part of the bigger picture.  Vast new sediment deposits extend down to FM1960.

Conclusion #3:

Even Harvey-strength currents could not cut through the mouth bar. Therefore, smaller floods won’t be able to either.

Conclusion #4:

The mouth bar creates a sediment dam in the river that will exacerbate flooding. If the mouth bar area is not dredged, it will cause higher-than-normal flooding on smaller-than-normal rainfall.

Google Earth shows that the area between the mouth bar and FM1960 comprises 1700 acres. According to the difference map, this area received an average of approximately 2 feet of sediment. This means the channel and lake lost 3400 acre feet of capacity in this area.

Conclusion #5:

The mouth bar must be removed immediately. It and adjacent shoal areas get higher with every passing day and storm as water becomes shallower. If the mouth bar is left in place, it will slow the river, causing the area upstream (that is now being dredged) to fill more rapidly than normal with sediment.

Difference Map Proves Mouth Bar Must Go NOW

The mouth-bar area was the focus of the Corps’ survey efforts. They have known for months that it is the major problem. As they stated in Galveston at a meeting I attended, it is the primary driver for backwater and upstream flooding. Their value engineering report also states that in the event of another heavy rainfall, there is a “near certain likelihood” that wide-spread flooding will occur impacting even more homes than before Harvey, due to the river’s inability to pass high volumes of water. See Page 2 for the words engineers almost never use without cause.

We’ve been lucky so far this hurricane season. But minor floods earlier this year on March 28/29 and July 4 proved how serious this problem is. Had the City not lowered the level of Lake Houston for July 4, homes almost certainly would have flooded according to Houston City Council Member Dave Martin.

This Week’s Holdups

At a meeting in Austin last week, the City, Army Corps, FEMA, County and State of Texas all agreed in principle that the mouth bar needs to be removed. Further, if it can be added to the current dredging project, taxpayers can likely save $17 million or more in mobilization fees for a second, separate project at a later date.

Only two hurdles remain: a disposal site for the dredged material and an environmental survey.

A large disposal site is already under review that is much closer to the area of concern than either of the two current sites.

The proposed disposal site’s proximity could save taxpayers tens of millions of dollars more.

However, the environmental survey could delay the project beyond April when current dredging is expected to finish. If so, that could also increase flood risk.

Trees on the mouth bar initially led the Corps to exclude the bar from dredging for two reasons: one was environmental, the other legal. According to the Stafford Act, the enabling legislation for FEMA, FEMA funds cannot be spent to fix things that existed before Harvey. The existence of the trees proved that at least part of the mouth bar existed before Harvey.

The “Mouth Bar.” Note the trees on the right end.

Let’s Get Real

If the trees on the island raise an environmental concern, leave the part of the island that existed pre-Harvey. Dredge the channel and other parts of the island first.

This area includes 3-5+ft of Harvey derived sediment which should qualify for FEMA disaster recovery funds under the Stafford Act based on the new TWDB map.

The longer we wait to dredge this island, the more vegetation will grow on it, the more resistant to erosion it will be, and the more expensive it will be to dredge.

Are the Army Corps and FEMA trying to save an invasive species that USDA wants to eradicate?

Close examination from a boat showed the trees in question to be Chinese tallow trees, an invasive species that the USDA has been trying to eradicate from here to Florida. It’s actually poisonous to local animals. If this tree costs taxpayers tens of millions of dollars in delays and opportunity costs, it will become the new poster child for government waste and folly…especially if Humble, Kingwood and Atascocita flood in the meantime. This is one delay I certainly wouldn’t want my name associated with. That’s the wrong way to go down in history.

This tree on the mouth bar which initially caused the Army Corps to exclude the bar from dredging is a Chinese tallow, an invasive species which the USDA is trying to eradicate. Note the heart-shaped, aspen-like leaves – the tell-tale identifier.

Meeting in Austin to Include Mouth Bar in Dredging Scope Ends Well, But Two Hurdles Still Exist

On Thursday, October 11, Council Member Dave Martin attended a follow up meeting to discuss Harvey recovery needs in the Lake Houston area, including the mouth bar. Regulatory agencies including the Texas Department of Emergency Management (TDEM), the Federal Emergency Management Agency (FEMA), the U.S. Army Corps of Engineers (USACE), along with staff from Texas Governor Greg Abbott’s office and the City of Houston also attended the meeting. At one point, Texas Division of Emergency Management Chief Nim Kidd reportedly told people he wasn’t going to let them leave until they reached agreement. The meeting lasted nine hours…without lunch. But at the end of the day, we’re a big step closer to removing the giant sand bar blocking the mouth of the San Jacinto River. Here’s how things reportedly played out.

City Requested Expansion of Scope

The City of Houston asked FEMA to give the U.S. Army Corps of Engineers (USACE) an emergency directive to remove siltation caused by Hurricane Harvey at the mouth of the West Fork of the San Jacinto. Further, to expedite the project and save remobilization fees, the City requested that this work piggyback on the original State of Texas Assistance Request (STAR).

Although  not officially approved yet, regulatory agencies reacted favorably to adding this to the original STAR request. However, two hurdles still exist.

Two Hurdles Remain for Mouth Bar Project

Before the mouth bar can be removed, two more hurdles must be cleared:

  • Identifying and permitting a disposal site
  • Complying with environmental regulations.

TDEM agreed to complete this additional work under an emergency request similar to the one that jumpstarted the initial dredging.

Said Houston City Council Member Dave Martin, “All parties involved are ready to make this work.”

Humble Land a Possibility

Barry Madden, an Humble landowner, with substantial acreage near the river and the mouth bar, has already met with officials about using his property as a potential disposal site. If acceptable, the proximity could save millions of tax dollars. Madden already has “fill” permits in place. So there may really only be one hurdle to clear.

Property owned by Barry Madden just west of Kings Lake Estates and south of the San Jacinto West Fork

Thank You to…

As discussed at the Kingwood Town Hall Meeting on Tuesday, October 9, this mouth bar and other Lake Houston area projects could not happen without the continuing efforts of TDEM, in particular Chief W. Nim Kidd;  Governor Abbott’s Chief Operating Officer, Reed Clay; City of Houston, Mayor Sylvester Turner; Chief Resiliency Officer, Stephen Costello; and Chief Recovery Officer, Marvin Odum.

Dredging Status: End of September

The U.S. Army Corps of Engineers has spread out across the West Fork of the San Jacinto River for its Emergency Dredging Project. Here is a visual status report from a trip up the river on Friday. I went from West Lake Houston Parkway past the US59 bridge to chronicle what has become an amphibious construction project.

The first dredge belonging to Callan Marine, a subcontractor to Great Lakes Dredge and Dock, has taken up position near the high tension power lines that connect Kingwood and Kings Lake Estates.

This is what the entire dredging assembly looks like.

It has been idling in the same position more than a week while pipeline and booster pumps are connected to it upstream.

Here’s what it looks like from the stern where dredged materials will enter the pipeline that takes them back to placement area #1.

This booster pump is required because of the distance to placement area #1 behind the apartments on Townsend near North Houston Avenue just south of the river.

Pilot boat shuttles pontoon with heavy equipment into place.

Heading upriver, more pipeline waits to be connected near the dredging command site.

At the command site, staff scurries to get the second dredge ready to launch before mid-October.

Dredge #2 owned by Great Lakes Dredge and Dock. This electric dredge will pump sediment to placement area #2 and require more booster pumps than the first dredge because of the length of the pipeline, almost five miles. Placement area #2 is on Sorters Road just south of Kingwood College.

Close up of the business end of the second dredge still at the dock. The rotating assembly stirs up sediment which is then suctioned into the pipeline and pumped to a placement area.Workers loading water into pipeline to get it to submerge. 

Pontoon with crane and pipeline welding equipment.  Sections of pipe waiting to be connected provide a convenient resting place for egrets and other water fowl.

The debris barges will offload their cargo here, where it will be transferred into these trucks and hauled away for processing or landfill.

Meanwhile, another crew scouts a route to placement area #2. Up the West Fork near Kingwood College, the river is so shallow, it may not be deep enough to float pipeline. If dredging in this reach of the river becomes necessary, it could delay the job and increase costs.

From this brief visual trip up the river, you can see that much prep work remains before full dredging can start. The second dredge has not yet launched and no pipeline has reached placement area 2. City officials have stated that the Corps hoped to be in full operation by mid-October. The 270-day clock for this project began ticking on August 19. Two hundred and twenty-nine days remain to the expected completion. Before the project is done, the Corps expected to move 1.8 million cubic yards of sand and sediment out of the river.

Dredging Almost Ready to Begin

The U.S. Army Corps of Engineers should begin dredging the West Fork of the San Jacinto River next week. The Corps expected to begin dredging this week, but a part failure for one of the dredges caused a slight delay. A replacement part is being remanufactured and shipped to the command site. The replacement part will help hold the dredge in place during operations and should arrive within days.

First dredge has been moved into river and is awaiting one final part.

With the exception of the replacement part, the first dredge is now virtually completed. It is 27 feet wide, 90 feet long and weighs 270 tons.

Second Dredge Also Now In the Water

A second dredge is also nearing completion. It is electrically powered and has also entered the river for final assembly. No pictures of it are available at this time. In the meantime, the rest of the operation is proceeding as scheduled.

4.5 Miles of Pipe

Workers have welded and weighted 4.5 miles – or almost 24,000 feet – of 24-inch dredge pipe made from 40-foot sections. The pipe will pump sand and sediment back to storage pits (placement sites) on both the north and south sides of the San Jacinto river. Each string of pipe is 1000 feet long. Booster pumps will connect the strings to keep sediment moving up-river and uphill.

Dredge pipe being moved into the West Fork of the San Jacinto in preparation for the start of dredging. Each of these strings is 1000 feet long. They weigh hundreds of thousands of pounds. These 24-inch-diameter pipes will eventually move more than 1.8 million cubic yards of sediment to two placement areas. 

A tender boat moves dredging pipeline into place along the banks of the San Jacinto river. Approximately 4.5 miles of 1,000 – foot  sections of High Density Polyethylene (HDPE) Pipe is being positioned for use next week when dredging should begin.

Even though the start date has been delayed, the date for completion has not.

Dredging Safety Warning

Jet skiers and recreational boaters have been sighted in the vicinity of the dredge command site. Dredging safety officers are asking West Fork San Jacinto recreational boaters to stay clear of submerged pipes and dredge platforms.

Stay away from this section of the river for your own safety. Even though you may be able to see operators, they may not be looking out for you as they struggle to move equipment weighing hundreds of tons. Operators are focused on their job, not you.

As the operational tempo of this project increases, so will the risk of accidents. So please keep your distance.
