Delta is proud to have a multidisciplinary team, and we strive to attract a diversity of experience, skillsets, and perspectives to enable us to challenge assumptions and create new approaches to long-standing problems.


The Hobart Sanitary/Stormwater District (hereinafter referred to as “HSD”) and Delta Institute are seeking proposals from qualified landscape architecture, design engineering, and environmental restoration firms interested in designing, implementing, and installing site improvements for the Duck Creek Tributary Restoration project, on behalf of HSD. The design and implementation work should reflect the recommendations and the findings of the Tributary to Duck Creek Stream Assessment Report (Appendix A). The selected proposer is expected to work closely with HSD, Delta Institute, and City stakeholders to ensure that the project’s design and implementation work is properly completed in a cost-effective, responsive, and timely manner. This Request for Proposals package represents a revised version of a previously released solicitation for design-build services for the project and has been amended to more explicitly request proposals for alternatives in the “build” phase of the project.

The HSD reserves the right to reject any and all RFP responses.

HSD and Delta Institute plan to implement Phase 1 of the Duck Creek Tributary Restoration Project (Phase 1 of 3 work scopes) in Hobart, Indiana. The Tributary connects Deep River with Duck Creek and is a segment of the Deep River Portage Burns Waterway Watershed. Proposed work products include streambank stabilization, restoration work, and the installation of a riparian buffer along 0.2 miles of the Tributary. The project will achieve various objectives, including: (1) addressing erosion and improving water quality by reducing runoff contaminants and sediment; (2) improving in-stream and riparian habitat quality; and (3) reducing overbank flooding onto adjacent County Line Road, by improving on-site infiltration.

The tributary restoration work will be undertaken across approximately 0.2 miles (or approximately 1,281 linear feet). The tributary transects three separate parcels, comprised entirely of agricultural and wetland features. Parcel sites 1 and 2 are privately-owned, and Parcel 3 is an existing utility easement owned by the Northern Indiana Public Service Company (NIPSCO). For execution of the project, conservation easement contracts will be executed between existing landowners, and the District.

Please review the linked RFP for the full Project Schedule.


The contract between the successful firm and HSD will be for specific activities and submittals and specifying a maximum not-to-exceed amount.


The contract shall commence after approval by the District and upon execution of a contract with HSD. The design portion of the project (including permitting and the development of a monitoring plan) is expected to be completed within a period not exceeding 5 months and the full build part of the contract is expected to be completed within a period not exceeding 6 months. The contract will expire December 31, 2022.


The selected landscaping/design/build firm(s) (hereinafter referred to as “Contractor”) must possess the ability, experience, and reputation for quality service necessary to produce high-quality and functional designs that prioritize storm water management and treatment benefits and community education. Firms with staff with some of the following credentials and licenses will be considered more qualified than those that do not have any: P.E., ASLA, and/or AIA.


The selected Contractor shall serve as part of the Project Team for the project and shall, at a minimum, complete the following:

  • Full design, construction, and restoration work along the 0.2 mile tributary corridor, including: invasive species removal, streambank stabilization and erosion control measures, enhancement of the channel riffles and pools, native re-vegetation work (both in-stream and along the channel slopes), and the installation of a riparian buffer.
  • Develop the necessary water resource models and perform calculations, as required to properly design the Project and to meet pollutant load reduction targets.
  • Completion of a Quality Assurance Project Plan (QAPP) to govern future flow monitoring and sampling activities at the Tributary.
  • Securing all necessary state and federal permits, on behalf of the HSD, to initiate construction.

Tasks included within the Scope of Service are:

1.) Data Review and Existing Conditions Review The Contractor shall review all existing surveys and conceptual project plans required for the preparation of full design and easement plans. The following surveys and plans were completed as part of the Tributary to Duck Creek Stream Assessment Report (Appendix A), authored by Cardno, dated September 27, 2019. The existing information includes:

  1. Topographic survey
  2. Geomorphic assessment
  3. Bank Erosion Hazard Index and Near Bank Stress Assessment
  4. Qualitative Habitat Evaluation Indices
  5. Sediment Survey
  6. Riparian Vegetation Survey
  7. Aquatic Organism and Riparian Wildlife Survey
  8. Water Quality Analysis
  9. Culvert Crossing Analysis
  10. Stream evaluation (Water Quality, Aquatic and Riparian Habitat, Flooding)
  11. Recommended improvement strategies for: Reed Canary Grass Removal; Native Plant Establishment; Bank Grading; and Enhanced Riffles and Pools
  12. Descriptions of Alternatives
  13. Conceptual Project Plan Sheets, including: Project site elevations; Utility easements; Cross sections; and Site plans and details
