The typical required inspection schedule in the Houston area is monthly. Self-performing these inspections can be costly and burdensome for permit holders. Our highly qualified inspectors are trained in all systems employed in this region with a special emphasis on prevention of costly maintenance issues before they become problematic. Our photo-documented Inspection Reports are inserted into the SWQMP documentation onsite, and/or can be e-mailed to management personnel located elsewhere.
Stormwater quality permits are valid for 1 year and therefore require annual renewal. To ensure that the system is functioning properly per the original design, a certification by a Professional Engineer is required. Other required re-permitting documentation includes an Owner’s Affidavit and Permit Application. Several local agencies also require photo documentation as well as a disposal manifest for cleanout of SWQ systems, if applicable.
Post-construction Certification is required at the completion of construction for all stormwater quality features in the region. This is a process that owners should monitor to ensure that the system they paid for is in place and functioning properly. Since SWQ systems are often underground, they are often overlooked and not included in the close-out process. Our experience has shown that all too often, the SWQ system specified is either not clean, not installed properly, or has not been installed at all. In some cases several years go by before these deficiencies are discovered, at which point the burden falls on the owner who is ultimately responsible for the SWQ permit. We regularly consult with our clients on new projects to help ensure that their SWQ systems are compliant.
SWQ System Cleanouts
Stormwater Quality treatment systems vary widely depending on a variety of factors including the size of the site, location, number of outfalls, and limits of construction. No matter what system is used, they all require regular maintenance. Maintenance requirements are based on the dictates of the Stormwater Quality Management Plan (SWQMP) as well as the manufacturer’s recommendations. Cleanouts must be properly documented and cutting corners puts owners at risk of fines and penalties. With this in mind we provide our clients with all necessary documentation to prove that removed pollutants have been disposed of properly and legally.
Stormwater Ponds pose a special problem for owners. Mowing slopes is much different than mowing flat ground, and requires specific equipment in order to prevent slope erosion and eventual failure requiring a costly pond remodel. We specialize in pond maintenance and take care in protecting your investment while keeping costs in check.
Much expense goes into creating detention ponds and establishing vegetation on their slopes. The problems come as the newly established vegetation becomes stressed due to the poor soils common on excavated slopes and lack of sufficient rainfall. This vegetation holds the soils in place and so it is vital that every effort be made to keep these grasses healthy. Regular fertilization is key to the long term health of slope vegetation but is often overlooked. We suggest the spring and fall application of fertilizer be applied to pond slopes. In cases where the vegetation is sparse or not taking root adequately, we recommend over seeding to more fully establish vegetation on the slope.
Pond stabilization has been traditionally problematic in the Houston area as our soils are predominately clay below the first few feet and contain little organic material essential to the establishment and stability of long term vegetation. Houston also experiences intense rain events frequently. Poor soils and intense rain events combine to create conditions which encourage erosion of slopes and eventual slope failure. With our extensive erosion control experience, we can help with even the most difficult of ponds, employing the latest technologies to solve erosion problems.
