13333 Kiefer Boulevard Grading Permit

The project proposes to establish approximately 12 +/- acres of wetlands, including vernal pools and swales. The subject property encompasses 586 +/- acres in its entirety; however, project area is approximately 317 +/- acres, of which 195 +/- acres will be preserved and protected in its current condition. The areas to be preserved will be demarked prior to beginning of construction. Spoils from excavation of the project site will be used to recreate natural vernal pool mound-intermound micro topography. The organic layer and the top 0.2 feet of topsoil from excavated areas will be stripped and used to vegetate the newly create uplands. The subgrade will be compacted by wheel-rolling with rubber-tired excavation equipment. The excavated basins and adjacent mounded watershed will be at fine grade to create natural appearing wetlands. The excavated basin at fine grade will allow for placement of 0.1 foot to 0.2 foot layer of vernal pool inoculum in each pool basin. Swales will be graded to direct flow from created pools to other existing jurisdictional wetlands. The salvaged topsoil will be spread and harrowed. The final grade will be left in optimal conditions for seeding. Disturbed and newly created uplands will also be vegetated by seeding with erosion control mix and mulching. An existing stream that is partially traversing the property is hydrologically connected to Deer Creek which is located south of the project area. This unnamed stream will be filled and abandoned. A new meandering and shallower channel will be created to provide hydraulic relief to the new vernal pool preserve.
