HRA Regular Session Meeting Date: 05/14/2013 By: Bruce Westby, Engineering /Public Works Information 5. 1. Title: Adopt Resolution 13 -05 -080 accepting Plans and Specifications and authorizing Advertisement for Bids for COR TWO (Sunwood Retail) Stage 1 Improvements Background: The COR TWO (Sunwood Retail) Stage 1 (common) improvements project area is bounded by Armstrong Boulevard to the west, Sunwood Drive to the east and north, and the initial COR development to the south. The Stage 1 improvements include minor site grading and construction of private bituminous access drives and utility trunk and service lines to serve the three platted commercial parcels. On -site stormwater treatment improvements, both temporary and permanent, are also proposed. On October 16, 2012, the HRA approved a work order with Landform Professional Services, LLC to prepare plans and specifications for the COR TWO Stage 1 improvements. While the plans and specifications for the Stage 1 improvements are not yet complete, city staff did recently receive and review the draft plans and have submitted initial review comments to Landform to be addressed. As of May 9th, city staff had not yet received the revised plans or a draft of the project specifications for review and approval. Once final plans and specifications are received, staff will promptly review them to ensure all plan review comments have been addressed to staff's satisfaction, and that the project specifications are accurate and complete. Observations /Alternatives: As was discussed during the April 9th HRA regular meeting, one of the three platted parcels includes the proposed McDonald's USA, LLC development in the northwest corner of the project site. McDonald's recently informed the city that they wish to develop the site this summer, with the intent of opening for business this fall. The HRA is therefore being asked to accept the plans and specifications and to authorize advertisement for bids prior to receipt of final plans and specifications in order to accommodate McDonald's desired development schedule. Staff then anticipates requesting acceptance of the bids and award of a contract for the COR TWO Stage 1 improvements at the HRA's June 1 lth regular meeting. Substantial completion of the project is anticipated to occur on or before August 2nd, with final completion on or before September 13th. McDonald's development team previously indicated they are generally agreeable to these milestones. As noted earlier, the plans include both temporary (two ponds) and permanent (below ground storage chamber) stormwater treatment improvements. One of the items the HRA is being asked to consider is whether to approve construction of the temporary or the permanent stormwater improvements at this time. The cost to construct the temporary at -grade ponding improvements is significantly less than the estimated cost for the permanent ponding improvements, which includes $39,000 for an underground storage structure. The temporary improvements could be constructed at this time then, once a development proposal is received for the south parcel and /or the Sophia Ramsey site, the permanent stormwater treatment improvements could be constructed at a later date with little sunk cost. On a related note, the plans call for the landscaped area around the east temporary stormwater pond, located on the Sophia Ramsey parcel between the initial COR development access drive and Sunwood Drive, to be irrigated using a temporary connection to the city's irrigation service line running along the west side of Sunwood Drive. Alternatives Alternative #1 - Accept plans and sepcifications and authorize advertisement for bids. Based on the existing real estate contract, this is Staffs preferred option. The improvements need to be constructed (with the potential for
