Public Works Committee 5.4. <br />Meeting Date: 01 / 18/2022 <br />By: Sean Sullivan, Community <br />Development <br />Title: <br />Consider Site Improvements to Parcel 46 and The Waterfront in the COR <br />Purpose/Background: <br />The purpose of this case if to obtain direction to consider making / funding site improvements to Parcel 46 and The <br />Waterfront in the COR. <br />Staff has been working with CBRE to market Parcel 46 in the COR. The site is generally low and needs fill and <br />compaction to make the site buildable. In addition, there is a wetland and a storm pond for Armstrong Blvd that do <br />not let the site be developed efficiently and to its full potential. The non -buildable status of the site and the <br />uncertainty in costs to make it developable has caused interested developers to pass on the site. <br />Over the past few years, we have had interest from developers showing the majority of the site being developed <br />with twin and cottage homes. The development plans reserve areas for retail and mixed uses residential. The EDA, <br />Planning Commission and City Council have generally accepted this development and the allocated land for each <br />use. Discussion with the developers always lead to the site not being ready and the costs needed to improve the site <br />for development and their uncertainty make the project unfeasible. The following items need to be addressed: <br />Fill Needed for Parcel 46 <br />There have been several attempts to determine the amount of fill needed for for this site. Attached are graphics <br />showing previous attempts to identify fill needs and sources. (Exhibit 1 - Fill for Parcel 46). This item needs to be <br />reviewed to determine the amount of fill that is actually needed and the cost to acquire, place and compact on the <br />site. <br />Wetland Mitigation and Relocation on Parcel 46 <br />Staff is in the process of putting together a schedule and potential pricing to either mitigating impacts to the existing <br />wetland at a 2:1 ratio by purchasing additional wetland credits in excess of what the existing City -owned banked <br />wetland credits will not cover, or by relocating the wetland on the site by constructing a new wetland within The <br />Waterfront park feature. Engineering will provide greater detail on this matter during the meeting. (See Site <br />Location Map) <br />Stormwater Pond Relocation for Parcel 46 <br />As part of the development of the site it is possible that the stormwater pond may need to be relocated. This could <br />be done as part of an new private development project or the City could be proactive and relocate the pond <br />strategically to another location when the fill work, and wetland relocation is being completed. (See Site location <br />Map) <br />The Waterfront Excavation and Rough Grade <br />The timing of The Waterfront park project is not scheduled within a particular year at this time. However, plans for <br />The Waterfront have envisioned enlarging and excavating the low area present on site as the beginning point for the <br />park project. This grading (excavation) could be used as a source for fill for parcel 46. It would make sense to <br />coordinate these activities if economically feasible. Additional things to consider include the ability/feasibility to <br />relocate the wetland from Parcel 46 on this site, and the probable need to line the water feature to prevent <br />infiltration since this site is within a wellhead protection area. Some preliminary work has been done with design <br />and site work (See Exhibit 2 - Soil Boring Reports), and concept plans and cost estimates have been generated for <br />
