PROJECT INTRODUCTION

• The City of T
• ledo is leading efforts to create

rain gardens and bioswales at Delaware Creek Park to improve water quality and habitat within the park property.

• The City received a grant from Ohio EPA

sourced through the U.S. EPA Great Lakes Restoration Initiative - Nonpoint Source program to help address the high levels of nutrients and sedimentation in the creek.

• Hull & Associates, Inc. was hired through a

competitive procurement process to provide professional science and engineering services to establish plans and oversee improvement installations.

• Sharing our initial considerations and

concepts to gain your ideas and input is an important part of this process.

DELAWARE CREEK OVERVIEW

• Delaware Creek is a 1.8-mile perennial stream that drains five square miles.
• It is located in the Maumee River watershed in south Toledo, Lucas County, Ohio.
• Delaware Creek enters the Maumee River from the west at river mile 9.2.
• Our project area is in the 0.9-mile lower reach of the creek and entirely within

the permanently protected City of Toledo Delaware Creek Park.

DELAWARE CREEK CONDITIONS

• Ohio EPA water quality sampling results in the

creek show:

• Significant sedimentation/siltation
• Excessive nitrate/nitrite and phosphorus
• Elevated levels of pesticides, chloride, and total

dissolved solids

• Ohio EPA biological sampling results in the creek

show:

• Above target for fish communities
• Below target for invertebrate communities
• “Very poor” narrative score and an

estimated 20% of the target goal

• Below target for aquatic habitat quality
• 74% of the target goal
• Decreased 4.5 points between 2006 and

2017 Ohio EPA sampling events

ANTICIPATED BENEFITS

• Mitigate some erosion concerns by capturing road runoff in

key locations

• Reduce sediment, nutrient and chemical loading from

stormwater into local waterways

• Improve habitat by installing native plants
