Also within Phase 2 is the existing pond within the future Park G, that is groundwater fed, under water rights certificate 41H-30158959, and as part of the park area improvements of the subdivision, the pond will be modified to meet the City requirements, within DNRC requirements. a. See the included Preliminary Construction drawings for a reference to both the surface water components. b. Baxter Creek and the unnamed stream-ditch are the only 2 surface water components existing on site, both of which have water flowing year-round. With the exception of the work to re-route the stream-ditch along the south property line (within the proposed open space), as well as the proposed re-routing of Baxter Creek to enhance the sinuosity of the Creek back to historical features (all of which is being reviewed through the ACOE & GCD), no work will be in or near the ditches for the subdivision. c. As noted above, both Baxter Creek and the stream ditch are currently being proposed to be re-routed. The preliminary plans for the stream-ditch are included in the preliminary Construction Drawings, and the Baxter Creek enhancement is under review with the ACOE and wetland specialists. d.
