Hendricks County On-Call Engineering
Hendricks County, Indiana
American Structurepoint has provided ongoing technical guidance to the Hendricks County Regional Sewer District (HCRSD) since 1992. In that time, the HCRSD has grown from a 60,000-gpd wastewater treatment plant with one customer to a 1.9-mgd facility with 5,500 customers and more than 200 miles of sewer.
Services provided on an ongoing basis include coordination and oversight for the privatized provider of wastewater collection and treatment services, review of developers' plans for conformity to district standards and master plan, verification of waste-load allocation assessments, and management of the work of construction inspectors for infrastructure projects within the jurisdiction of the District. Attendance at all public meetings of the HCRSD Board and providing periodic activity reports are also included in the scope of work. Bi-monthly meetings with the board and regular interface with the privatization vendor have resulted in a well-operated system. Additional master planning efforts have resulted in expansion as the HCRSD works with the existing wastewater operations in the county to provide wastewater treatment options to unsewered areas. For the McCracken Creek mitigation site, American Structurepoint prepared design plans for approximately 3.3 acres of forested wetland mitigation for impacts along a portion of the new Ronald Reagan Parkway. Before the mitigation site was designed, we prepared a suitability study indentifying potential mitigation sites near the project corridor. Initial screening activities included an examination of existing topography, mapped soils, watershed size, potential to develop wetland hydrology, and existing and planned land use. After a suitable mitigation site was selected, American Structurepoint developed mitigation plans designing a wetland cell strategically placed on the landscape where it would be hydrologically connected to an adjacent stream channel during flood events. Minor grading was required to construct low berms to expand adjacent wetland areas, retain floodwater, and capture runoff during smaller rainfall events. The site was planted with a wooded wetland understory seed mix and hydrophytic tree species. The proposed forested wetland mitigation will add to the natural habitat currently existing adjacent to the site.
