 2. Park District - Chuck Papanos

 a. Warming Shelter Remodel
 Construction has started on the Warming Shelter. The Park District
 hopes to have the project completed before winter.
 b. Porch-Type Swings
 A resident asked that the Riverwalk Commission (RWC) consider
 adding porch-type swings to the Riverwalk. Novack stated that the
 RWC had discussed a request for the same type of swing several
 months ago. The outcome of the request was denied as the swings
 could cause a safety issue. Papanos will relate this to the resident.
 c. Bicycle Signage

 Buddingh shared that she was on the east extension when she saw a
 father and daughter dismount when they noticed the new bicycle
 dismount signage. Unfortunately, she saw them riding their bikes near
 Rotary Hill later in the day. The question of installing additional bike
 dismount signage was raised.


 3. Naperville Jaycees Park - Geoff Roehll

 The City and Naperville Area Chamber of Commerce hosted a
 well-attended ground breaking ceremony on September 18, 2018.
 Construction began soon after. Barring any weather related issues, the
 project is expected to be substantially completed this fall with the
 landscaping and final touches completed in the spring.


 4. Harmony Park - Geoff Roehll

 The Rotary Club is hosting a ground breaking for Harmony Park on
 October 3, 2018. The club related that the instruments have shipped and
 construction should commence shortly. Once the project starts, it should
 take approximately four weeks to complete, assuming there are no weather
 issues.


 5. Maintenance Policy for New Additions to the Riverwalk - Jan Erickson

 Erickson reported that the subcommittee is working on updating the
 existing policy to address funding for maintenance for future amenities to
 the Riverwalk. A draft may be available for the November PDC meeting.


 6. Moser Tower Assessment - Brian Dusak/Jake Wolf

 The draft addendum to the Moser Tower Assessment Report was
 submitted in the middle of September. Links to the draft addendum as well
 as the original 2017 report are available on the Riverwalk webpage on the
 City’s website. A press briefing was held on September 27, 2018.

 Dusak reviewed the background of the project. The team that did the work
 for the second phase of assessment consists of Engineering Resource
 (ERA), EChem, Brush Architects and Golf Construction. The team focused
 on material assessment, durability, structural service life, aesthetics and
 accessibility for possible repairs.

 Wolf summarized some of the findings. He stated that prior to the
 additional exploration, there were many unknowns regarding how the
 structure was constructed as it had been built in phases with different

 architects and contractors with each phase. He explained that following the
 additional testing, most of the unknowns have been answered. He further
 explained how the structure gains its stability with the post tensioned rods,
 compression rings and girders connected to concrete.

 The findings show that the tower is currently structurally sound, in
 serviceable condition and can be repaired. There are areas that need
 attention to address existing corrosion and concrete deterioration. The
 concrete encased post-tensioned rods appear to be in good condition.
 Several of the metal components show evidence of corrosion which must
 be cleaned, painted and sealed or flashed to prevent further corrosion.
 There are two types of concrete; pre-cast and cast-in-place. Both have
 evidence of cracking and spalling, allowing water intrusion to cause steel
 corrosion. Currently, these issues can be repaired. The biggest issue is
 water intrusion and the freeze-thaw that occurs in Illinois. Abating the
 moisture is key to the future of the tower.

 Moser Tower is in a proactive repair state where work and repairs can be
 designed to slow down or prevent additional issues. If left alone, the tower
 would likely continue to deteriorate into a reactive state where more
 significant, immediate, and more costly steps would need to be taken.

 ERA will keep the format consistent with the original report. The draft
 addendum will hone in on the new findings, an updated cost opinion and
 clarify assumptions made in the original report. It will take several months
 for the Riverwalk Commission to fully review, digest and discuss the
 information presented in the addendum prior to making a recommendation
 to the City Council. In coming months, the Riverwalk Commission will
 discuss various options for the process moving forward.
