Town Center 3rd Addition - Site Plan/Coborn's July 8, 2004, Revised July 23, 2004 Page 3 of 9 · The pond elevations on Page 9 do not match the information shown on the other sheets. · The retaining wall around the plan is called out'as combined retaining wall and building footing. Signed engineering drawings will be need to be submitted to the building inspection department for review prior to approval of this concept. · Grade transitions should be smoothed out, the current plans show grade changes of 2%+ on different sides of contour lines. Utility Plan: We offer the following comments on the utility plan. · The hydrant in front of the large retail building on page 9 conflicts with the storm water lead to the build and is too close to the catch basin. Move the hydrant to a different island, The landscaping plan shows a tree in the same location as this hydrant. Additional coordination of the plans is necessary. · Coordinate with the MSA plans to remove the sanitary sewer and water service along Armstrong Boulevard west of the pond. · The proposed watermain layout is being reviewed by the city consultant to verify adequacy of hydrant flows. This information may not be available before this review letter is sent. The results of the review will be sent to URS. · The fire inspector is reviewing the hydrant layout for coverage of the site. Comments will be provided during the review process. · The storm water plan approved with the final plat of Ramsey Town Center is being modified to allow more room for development on this site. Meetings have been held to resolve the changes. The changes included making the southwest pond smaller, increasing the size of other ponds and changing pipe sizes and alignments. Details to be resolved include verifying that there is adequate clem-ance between the pipes after the change in size, verifying the clearance around the new manholes and verifying cover over the pipe. These issues were discussed at a meeting held July 1, 2004 and work Was to start on checking these specific issues. The RTC development will require additional water supply wells. This was anticipated and a lot was platted on the east side of Zeolite' Street for a future well. An exploratory well has been developed on the lot and the plans for pipe to connect this well with the city water distribution system have been issued for construction. The proposed gas station on the site is within the well head protection area for this future well. Gas Stations are not explicitly prohibited in well head protection areas, however additional protection measures are required for the underground st°rage tanks and dispensing areas. Plans for these additional controls must be submitted to the city ~br approval. Relocation of the well has been suggested by the developer. This may be acceptable to the city if a suitable site for the new well can be ~'ound. The developer will be responsible for reimbursing the city expenditures to date on the current well site and reimbursing the city for the cost of pipe installed but not used to connect to the original well.
