Urban Conservation Projects Request for Pre-Applications

IDALS is accepting pre-applications for projects that demonstrate strong ties to the Iowa Nutrient Reduction Strategy. These projects will focus on adoption and implementation of urban conservation practices that provide nutrient load reductions to water resources in combination with outreach and education components demonstrating how projects will work to support the nonpoint source action items outlined in Section 1 of the Iowa Nutrient Reduction Strategy. The Iowa Nutrient Reduction Strategy can be viewed at http://www.nutrientstrategy.iastate.edu.

Applicants should demonstrate the ability to deliver stormwater management strategies and practices. Strong partnerships must be demonstrated with any stakeholders that will be contributing significant resources to the project.

These projects can range from site scale to watershed scale stormwater management practices (a single bioretention cell vs a stormwater wetland). Projects may utilize one or multiple stormwater management practices to manage the water quality improvement goals. The practices must treat for water quality volume, but they may comprehensively manage multiple storm events including the entire unified sizing criteria storms, when possible or practical. This approach can provide large scale water quality and quantity benefits to the applicant.

Priority will be given to applications that can demonstrate the ability to rapidly implement the project and practices funded under this RFPA.
