SCOPE OF SERVICES
Sandy Creek Dam Removal
Hampton. Lenzini and Renwick. Inc. (HLR) has prepared this proposal letter agreement to complete the concept
design for the Sandy Creek Dam Removal project. This project is located at an in-line stormwater basin on Sandy
Creek between Airlite Street and Highland Avenue in Elgin, Kane County, Illinois. The existing basin was constructed
as a part of the Lincolnwood Terrace subdivision development in 1992 for stormwater storage and aesthetic purposes.
The basin is controlled by a dam connected to the upstream wingwalls of the concrete box culvert crossing Highland
Avenue, impounding Sandy Creek upstream to Airlite Street. While the basin was designed and originally functioned
as an open pond, it has filled in with sediment over time. This is a result of large sediment discharge events paired
with the typical sediment processes of in-line basins. This issue has worsened in recent years, exhibited by the
development of dense stands of invasive vegetation such as cattail and phragmites in areas that previously were
open water. The current status of the basin not only negatively impacts the aesthetics of the subdivision. but also the
functional value of Sandy Creek by disrupting sediment transport. inhibiting fish passage, and deteriorating water
quality. Removing the dam will address these impairments by draining the basin and restoring this reach of Sandy
Creek.
The preliminary scope of this project will consist of the development of a concept design for the removal of the dam
and restoration of Sandy Creek upstream to Airlite Street. Detailed topographic. bathymetric. and sediment survey of
the basin and surrounding area will be acquired to inform the concept design. Initial coordination with applicable
regulatory agencies will be conducted in order to understand the permit requirements associated with this work and
how the concept design can be tailored to best adhere to these requirements. Based on the concept design
developed, an application for the IEPA Section 319(h) Nonpoint Source Pollution Control Financial Assistance
Program will be submitted in order to fund the detailed design and construction of this work. The scope of services is
detailed below. A detailed cost breakdown for these services is provided in Exhibit A.
SCOPE OF SERVICES
Task 1: Bathymetric/Sediment Survey Services
Bathymetric survey will be completed with GPS base and receivers to determine sediment depths and distribution.
which will provide an estimate for the total volume of deposited sediment. HLR will survey the bottom of the sediment
utilizing a long probe that will be forced through the sediment to refusal, assuming that is the solid subbase.The limits
will be 10 feet beyond the top of banks. Structure surveys will be completed for the existing dam and the culvert
crossing Highland Avenue. Inverts will be collected for all culverts around the shore. The project will use Illinois East
State Plane Coordinates and NAVD 1988 vertical datum. A volume calculation will be made for the elevation
differences between the soft and hard bottom to quantify deposited sediment. Deliverables for Task 1 include a set
of exhibits showing the stream/basin bathymetry and sediment depth.
Task 2: Preliminary Engineering—Concept Design, Permit Coordination, and Grant Application
HLR will prepare a concept design for the removal of the dam and restoration of Sandy Creek between Airlite Street
and Highland Avenue. This concept design will be informed by the bathymetric/sediment survey and occur
concurrently with initial permit coordination. A site visit will be conducted to assess current basin conditions and
collect photos.

Sandy Creek Dam Removal
August 25, 2026
Page J 2
The following criteria will motivate the concept design:
• Remove the dam with minimal impact to the existing Highland Avenue culvert.
• Minimize the immediate transport of sediment that has deposited in the basin to downstream reaches of
Sandy Creek.
• Mitigate the potential for increased flood risk along Sandy Creek due to the dam removal.
• Restore approximately 500 linear feet of Sandy Creek by removing the impoundment and establishing
morphology typical of nearby upstream and downstream reaches.
• Eliminate the existing non-native and invasive vegetation and establish native vegetation typical of high-
quality local stream corridors.
Using these criteria, the proposed concept design will provide a proof-of-concept plan that restores the functional
value of this reach of Sandy Creek by activating sediment transport processes, improving the ecological value of the
stream corridor, restoring fish passage, and improving water quality. The primary water quality improvements that
will be targeted are increased dissolved oxygen, reduced suspended solids and nutrients, and decreased algal
growth.
Due to the dynamic and circumstantial nature of permitting for dam removal projects in recent years,the scope of the
concept design is fluid and will depend on input from relevant regulatory agencies such as USACE, IDNR-OWR.
IDNR Dam Safety. IEPA. and Kane County Stormwater Management. The primary uncertainties at this time are the
level of effort required for minimizing downstream sediment transport at the time of dam removal,as well as the extent
to which the impoundment area must be restored via active intervention. At this time, two preliminary alternative
pathways for the implementation of this project are:
A. Low intervention
1. Notch the dam slowly to dewater the impoundment to minimize downstream sediment export.
2. Allow the stream upstream of dam to form new alignment between Airlite Street and Highland Avenue
3. Adaptive management of newly formed stream via erosion control blanket, seed and plug installation.
and minor rock installation as needed based on assessment of changing stream conditions.
B. High intervention
1. Dewater the basin and remove mobile sediment.
2. Remove the dam.
3. Restore the stream between Airlite Street and Highland Avenue by regrading a new alignment and
installing erosion control blanket, seed, plugs, and rock.
These and other pathways will be investigated as a part of this work, largely driven by constructability and
permittability considerations. Coordination with regulatory agencies will be conducted in order to ascertain permit
requirements; pre-application meetings will be held if allowed by these agencies. Once the permit requirements and
scope of the concept design are refined, a concept plan view will be developed, including:
• Method and timing of dam removal
• Schematic of best management practices to restore Sandy Creek
• Anticipated planting zones and preliminary seeding/planting mix
• Dewatering and soil erosion & sediment control practices as needed
An application will be prepared for the IEPA Section 319(h) Nonpoint Source Pollution Control Financial Assistance
Program to fund detailed design, permitting. and construction. The grant application consists of concept plans,
application forms on the Euna grants platform, letters of support, estimate of probable cost, preliminary pollutant
loading reduction analysis using the Pollutant Load Estimation Tool (PLET), and a project narrative.

upcoming milestones.
Additionally, this task covers the presentation of findings. HLR will prepare a presentation summarizing the findings
of the Sandy Creek Dam Removal project and discussing proposed solutions at one Tyler Creek Watershed Coalition
Meeting and one Lincolnwood Terrace HOA board meeting.
Task 4: Quality Assurance and Project Administration
This task includes project administration, and quality assurance and quality control per HLR's QA/QC plan. Project
management and administration will last throughout the expected duration of the project. Management and
administration are necessary to ensure the successful completion of the project. The expected activities within this
task include:
