differential rising and falling between the slabs and construction joints as listed in the letter and recommended be done. The sidewalk tree grates heaving is again a water infiltration issue which can and should be managed at the sub-grade design level. Mr. O'Malley recommended the Commission review the proposal for amendment using the guidelines of chapter 1126, thereby following the requirements for an original plan. 1VIr. Hartman, representing Developers Diversified, advised that in 2000 the plaza received approval to renovate the plaza which included fagade changes and using multi colored concrete sidewallcs with tree planters. Since the work was completed there has been a substantial amount of concrete heaving. Therefore a year ago URS was hired to advise the owners as to why this was occurring and to then present a solution to fix the issue. DDR's major concern is rislc management as there have been a number of trips and falls resulting in injuries. URS advised that there was not proper drainage under the sidewalks. URS designed a plan to replace all the concrete and sub-grading to install a drainage pipe system which would be tied into the stormwater system and was started last year. In 2005 DDR received a minor change approval to use monotone concrete and, instead of a 2-foot saw- cut pattern, a 4-foot diagonal saw-cut pattern was used along the far-east section of the plaza. The new photos submitted show existing concrete installed in 2000 and concrete installed in 2005. The last page shows the area in which concrete was replaced last year and shows the area to be replaced in 2006. However, as Home Depot is under a ground lease they are responsible for their own sidewalks. URS advised him that the amount of heaving was do to the different compositions of each of the color pours. Their plan is to replace all sidewalks and do what they can to eliminate water getting under the sidewalks. The newly replaced section will have drains tied into the sewer system and monotone cement with 4-foot saw-cuts made in a diagonal pattern. It is their preference to not replace the trees along the sidewalks as they are a rislc-management issue and the trees do not thrive in the area. They believe that the trees would survive better if relocated. Mr. Yager reviewed that the 1999 renovation included fagade changes, landscaping improvements and color concrete program to create a specific look. He questioned if the original architect was questioned as to why the concrete was heaving and questioned the URS report. The URS report clearly states that it is an underground water issue which may be impacted by the number of construction joints used as opposed to the number of control joints. If it is truly the intent of DDR to properly correct the problem by removing all the sidewalks and installing the proper drainage system, then why can't the original plan be re-implemented using the color concrete. He has no objections to larger control joints/patterns to help the concrete last longer. However without the original plans the Commission has no way of lcnowing the impact the requested changes will have on the overall aesthetics of the plaza. He recommends that color concrete with larger control joints be used in the replacement. He would never recommend removing the trees as they were a critical element of the original design used to break up the starkness of the buildings. Furthermore the original plans clearly stated that there was to be no carts or merchandise along the sidewalks as they create high risk management issues such as bloclcing the sidewalks and are tripping hazards. Mr. Malone advised that he had no objection to monotone concrete and could not address structural issues as it was not his field. His opinion has not changed since the last meeting regarding the trees. If they are properly installed and maintained there is no reason trees would not survive along the sidewalks. If it is within the commissions right to stipulate that carts, creates or any merchandise is not allowed to be along the sidewalks then that is his 2
