NAWA

INTRODUCTION. The 1996 Amendments to the Safe Drinking Water Act establish a framework for states to evaluate public water systems. Ohio's Source Water Assessment and Protection Program helps these systems protect their water sources from contamination. This assessment:

• Identifies the water source protection area based on well location
• Catalogs potential contaminant sources in the area
• Evaluates the vulnerability of the water source
• Recommends protective strategies

The goal is providing information that NAWA can use to safeguard their water sources.

SYSTEM INFORMATION & GEOLOGY. NAWA serves approximately 25,000 residents in and around Tipp City, Miami County, Ohio. The system operates 7 wells that pump about 2.9 million gallons daily from a sand and gravel aquifer within the Great Miami Buried Valley system. No protective confining layer exists near the wellfield that could shield the aquifer from surface contaminants. Water depth is less than 20 feet below ground, and local soils are sandy loams with moderate drainage, allowing rainwater to infiltrate rather than run off.

The topography is generally flat. Groundwater replenishment comes from underground flow from higher to lower elevations and approximately six inches of annual precipitation that filters through the soil. Surface water in NAWA's wellfield area flows generally toward the south-southwest.

PROTECTION AREA. NAWA's wellfield protection area includes two zones. The "inner protection zones" represent areas that supply water to NAWA's wells within one year of pumping. Chemical spills here pose an immediate threat and require stricter protection. The "outer protection zone" contributes water when wells are pumped for five years. Together, these form the complete water supply protection area.

Why does the City need a new transportation plan?

1. The previous Transportation Plan from 1999 is outdated and no longer aligns with PlanSJ
2. Policy TM1 requires developing a comprehensive Transportation Strategic Plan for a multi-modal transportation system
3. Transportation and land use are closely interconnected - the transportation network influences land development patterns, which in turn affect transportation demand
4. Current accessibility can be improved
5. A new plan aims to reduce automobile dependence and increase transit and active transportation usage

Why invest in another study when we already have reports on trails and bikeways?

This project builds on previous work to create a comprehensive 25-year transportation development strategy. Unlike the 1999 study, this takes an integrated approach incorporating parking, active transportation, and transit considerations. Additionally, the City's future land use plan has changed with the adoption of a new municipal plan, necessitating an updated transportation system that supports these new land use patterns.

Have any recommendations from previous transportation-related studies been implemented?

Yes, progress has occurred on active transportation initiatives such as the Uptown Bike parking study and the Trails and Bikeways Master Plan. The new Zoning By-law now requires bicycle parking for certain developments. Key recommendations from the 1999 Transportation Study that have been implemented include the One Mile interchange development.
