Project Overview

The project includes compilation of existing data, necessary field work, and development and evaluation of reasonable alternatives to select a feasible major drainageway plan and Flood Hazard Area Delineation (FHAD) for the study area. Factors such as existing and future land use, cost-benefit analysis, existing and anticipated drainage or flooding problems, existing and anticipated erosion problems, stormwater quality, right-of-way needs, existing wetlands and riparian zones, open space and wildlife benefits, aesthetic concerns, and legal issues will be considered. Conceptual plans will be developed using the criteria and policies of the Urban Drainage and Flood Control District and applicable local, state and federal regulations.

Phase A of the project will include all studies and data gathering needed to prepare baseline hydrology and an alternatives analysis report. The FHAD will also be developed. A preferred alternative will then be selected by the project sponsors. Phase B of the project will include preliminary design of the selected alternative. View the project timeline here.

Field Investigation

As part of the work performed for Phase A of the Piney Creek Major Drainageway Planning project, an in-depth field investigation was completed to document existing conditions, identify potential problem areas, and validate hydraulic and sediment-transport models along the main stem of Piney Creek and Antelope Creek. This documentation included acquisition of geo-referenced photography, which is now available for review using Google Earth or other KML-capable earth viewer software. If you do not have such a viewer installed on your computer, you may download Google Earth for free from http://earth.google.com.
