Town Center 3~'d Addition - Site Plan/Coburns ' July 8. !004 Page 3 or'7 · The retaining wall around the plan is called out as combined retaining wall and building tholing. Signed engineering drawings will be need to be submitted to the building inspection department for review prior to approval of this concept. · Grade transitio2s should be smoothed out, the current plans show grade changes of 2%+ on different sides of contour lines. Utility Plan: We offer the l¥11o,,ving 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 dit'ferent island. The landscaping plan shows a tree in the same location as this hydrant. Additional coordination of the plans is necessa~. · Coordinate with the MBA plans to remove the sanitm¥ 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 t-'or 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 clearance 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 tbr pipe 50 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 tbr this future well. Gas Stations are not explicitly prohibited in well head protection areas, however additional protection measures are required for the under~ound storage 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 tbr the new well can be found. The developer will be responsible i'or reimbursing the city expenditures to date on the current well site and reimbursing ~:he city kbr the cost o'f pipe installed but not used to connect to the original well. Landscaping: City Code requires one (!) tree per every fifty (50) lineal feet of site perimeter or 1,000 square feet of building coverage, whichever is greater, be planted throughout the site. A portion o~' these trees should be installed along the public road frontage at no greater than thirty- five (35') ~'eet on center. City Code also requires that no less than 25°./0 of the trees planted be deciduous and no less than 25% coniferous. Furthermore, City. Code'requires that no more than 8a
