This guide summarizes common incentives, eligibility, inspection and compliance pathways administered by city departments so owners can plan installation, apply for credits, and understand enforcement.

Overview

Indianapolis administers stormwater management and related incentives at the municipal level through city departments that implement the stormwater utility, permitting, and inspection programs. Incentives commonly take the form of fee credits or technical assistance for projects that reduce stormwater runoff on private property.

Check city program pages or contact the department for project-specific guidance.

Who is eligible

  • Private residential property owners installing qualifying green infrastructure.
  • Commercial and institutional properties that reduce impervious area or treat runoff to city standards.
  • Multi-property developments that enroll under a single utility account or parcel-based credit program.

Common incentive types

  • Stormwater utility fee credits based on verified reduction in billed impervious area or on-site retention.
  • Technical assistance, design guidance, or demonstration projects offered by city sustainability or stormwater staff.
  • Priority permitting or plan-review guidance for qualifying low-impact development (LID) projects.

Installation, technical review, and inspections

Most incentive programs require pre-approval or post-construction verification by inspectors. Plans may need to show sizing, planting, overflow, and maintenance access. After installation, city staff may perform inspections to confirm compliance before issuing credits or closing permits.

Obtain pre-approval where available to avoid ineligible installations.
