INTRODUCTION

2007-2012-2013
2017*2019
The attached resolution authorizes the award of the public improvement construction
contract for the Tiffany Court - Lead Mine Sinkhole Remediation Project.
BACKGROUND
In September 2018, a large sinkhole developed on private property (2792 Tiffany Court)
which we believe rests on or very near an historically large sub-terrainian crevice
(Stewart's Crevice) related to abandoned lead / zinc mining operations of the 1800's,
based on historical reference in Samuel Calvin's Geology of Dubuque mapped records
of 1858 and 1899.
The subsurface collapse has impacted the nearby residences and has the potential to
impact public infrastructure in and on Tiffany Court. City staff have worked with the
homeowners, Bob and Barb Freidman, and Steve and Kathleen Abba, providing
technical oversite using tried engineered methods of mitigation since the onset of the
sinkhole. Unfortunately, remediation and mitigation efforts have been unsuccessful and
there continues to be on -going funneling and subsidence.
Both property owners, the Freidman's and the Abbas, have indicated that their
respective property owner's insurance does not provide coverage for lead mine sinkhole
remediation. The property owners have also reached out to legislative and
congressional staff to inquire and request funding assistance at the state and federal
levels.
In December 2020, Mr. Freidman sent a letter to Governor Kim Reynolds requesting
assistance in mitigating the lead mine sinkhole. In February 2021, the Governor issued
a letter which authorized Iowa Department of Agriculture and Land Stewardship (IDALS)
to utilize funds from Iowa's coal regulatory account, pursuant to Iowa Code section
207.21(2)(b), to mitigate the lead mine subsidence located at 2784 and 2792 Tiffany
Court.
Following this announcement, IDALS approached the City to inquire if the City would be
agreeable to acting as the Local Public Agency and Contracting Authority for the lead
mine sinkhole remediation and mitigation project.
Following the request, the City Attorney's Office worked directly with the State Attorney
Generals Office to prepare a Cooperative 28E Agreement between the City and IDALS.
The Agreement, to the fullest extent permitted by law, indemnifies and holds harmless
each party from and against all claims, losses, damages, liabilities. In May 2021, per
City Council approval of Resolution 178-21, the Mayor executed the Cooperative 28E
Agreement with the Iowa Department of Agriculture and Land Stewardship.
SITE ACCESS AGREEMENT
Pursuant to the terms of the 28E Agreement, the City developed and acquired signed
Site Access Agreements with both property owners, the Freidmans and the Abbas,
holding the City and IDLAS harmless in the event of any unforeseen damages resulting
from the lead mine sinkhole remediation and mitigation efforts.
The Site Access Agreement clarifies that the City and IDLAS will be completing the
remediation and mitigation work in the interest of public health, safety, general welfare,
private property, and to protect public property and infrastructure.
The Site Access Agreement also states and makes no guarantees about long term
performance of the constructed remediation and mitigation, nor may it be construed to
provide any protections to any person or property from future subsidence at 2784 and
2792 Tiffany Court after the remediation and mitigation is completed.

IDALS will reimburse the City for allowable expenditures up to $150,000 for work
performed that is directly related to the remediation of the lead mine subsidence. If at
any point project costs are anticipated to exceed $150,000, IDALS must approve all
additional costs. The City and IDALS will be responsible for their own respective
administrative costs associated with the 28E Agreement, including the costs of
administration, resources, and employees' labor on the project.
Per the Site Access Agreement, the property owners have agreed, are solely
responsible for the repair or replacement of any sidewalks, driveways, or landscaping
and the cost thereof which may result from the remediation work and that City and
IDALS will have no responsibility for such repair or replacement or any ineligible cost.
Per the bid received, the cost for private sidewalk replacement was $23,030.00. The
property owners may elect to have this work completed as part of the project and shall
reimburse the City or may elect to have the sidewalk work performed by their own
contractor in which the $23,030.00 cost would be deleted from the project contract.
REQUESTED ACTION
Based on the concurrence from Iowa Department of Agriculture and Land Stewardship,
the Mayor and City Council is requested to award the construction contract for the
Tiffany Court - Lead Mine Sinkhole Remediation Project through adoption of the
attached resolution to S&S Builders in the amount of $163,666.09.
