This study identifies the drainage and flooding hazards within the watershed and develops alternatives to address those hazards. It is a comprehensive study that estimates flood and erosion potential, maps watercourses, identifies existing and potential problems and develops preliminary solutions and standards for sound floodplain and stormwater management.
Water as we talk in terms of growth, habitat protection and it is probably the limiting natural resource in this valley and region. Sustainability was drafted into the groundwater proposal in 1980 and it required all of the Active Management Areas of Arizona to achieve a safe deal within 45 years after balance of plan. The groundwater code had a very unique way to meet the assured water supply requirements. Before you can subdivide property you have to show that there is adequate water supply for 100 years.
Millstone Manor #6 is a subdivision that was recorded in the mid-1950's. All records indicate no engineering took place with regards to potential for drainage improvements. This report will address what the natural floodprone areas are and will recommend how future permits should be processed.
The Sutherland Valley is a broad, geologically-controlled floodplain. This study attempts to quantify the depth and extent of flooding so that floodplain permits can be issued for development which meets local and federal restrictions.
