The City of Grants Pass is pleased to introduce its Stormwater Management Manual (SWMM). This SWMM will alter how our developing community reduces, controls and treats stormwater runoff.
The Stormwater Management Manual utilizes a methodical approach to managing stormwater using Low Impact Development principles. This approach preserves and mimics the historical natural water cycle and helps to attain State mandated water quality goals. Low Impact Development varies greatly from historically used stormwater control measures and will change how development occurs. This change will help the community manage the quantity and quality of runoff from the City resulting in cleaner rivers and streams.
