The May 13, 2004 minutes were approved with corrections on page 2, points#5 and 7. Cornerstone—Preliminary/Final Plat Engineering Comments by Joe Wywrot 1) Point#1 under Plat—The curves at the NW and SW eye-brows cul-de-sacs are too tight and do not comply with the ordinance, stated at 100 feet. Mr. Wywrot was not aware that City Council had voted to okay roadway alignment; however this was subject to engineering approval. Mr. Huinker suggested he would look at redesigning the SW area at 75-80' (lot 35) and making the NW cul-de-sac ( lot 37) radius 100'. Mr. Huinker stated the connector to the City pedestrian trail would be between the Lot 14-15. He will detail the spot elevation, with a 5% slope, and include in the table on the last page. Mr. Schoppe stated that a direct alignment with the development to the south, or an offshoot up to 200' east (into the residential areas) should not be a problem, however the commercial entrance alignment will need to be addressed at a later time. 2) Point#5 under plat—Mr. Wywrot stated the 80' consistent dimension along the south Greenbriar Rd. ROW way is shown inaccurately. Greenbriar Rd. is now 39' back to back in a 40' ROW. In anticipation of roadways and intersection planning, the revision needs to be made. 3) Point# 1 under Sheet 4 - Mr. Huinker suggested the City would benefit by having additional sewer manholes with the sewer on the "outside" of the circle, which Mr. Dhuse was in favor of Mr. Wywrot asked that the distance of water mains under the pavements would be minimized. 4) Point #2 under Sheet 4—Mr. Wywrot stated the Greenbriar Road street lighting is currently at 600 foot lighting, understanding that the development on the north would have 300 foot lighting. Mr. Huinker will accommodate the City's request. 5) Point#4 under Sheet 4—Mr. Huinker will make sketches of manhole adjustments and fax to Joe Wywrot. 6) Point#1 under Sheet 10—Mr. Wywrot stated the City does not want a stop sign on the 100 Road/Greenbriar Rd. intersection, as he does not believe traffic will warrant it. It will be a collector road. The bi-directional turnkey in the proximity 2 of the intersection needs to be eliminated and the re-striping of the center lane will be completed. 7) Points#1 under Sheet 12 and 13 —Mr. Wywrot suggested merging the ponds on the two properties, but Mr. Sperling stated there would be problems with maintenance and Laura Brown suggested the easements for the walking trail may be lost. Mr. Sperling suggested they would probably make their detention ponds "wet" and make them deeper. Mr. Wywrot stated storm sewers coming in the bay area need to be oriented to keep flushing at a maximum for algae cleansing. The restrictor rates for the ponds will need to be reduced to simulate for 2, 25-100 year design storms. 8) Mr. Wywrot suggested that the pedestrian trail between lots 14 and 15 needs additional detail on the plat. This trail will provide access to Rt. 47. The trail should be identified as 5' and will be asphalt. Zoning comments by Anna Kurtzman 1) Lot B should have a 30' not 20' landscaping. 2) Ms. Kurtzman suggests the landscape buffer should be consistent at 30', and it can be depicted as a"lot". Mr. Schoppe suggests there is currently not an ordinance requiring this. 3) Points 4 & 5 - Lots 1 & 32 building setback lines to be 30' to incorporate the corners. 4) Additional information is needed for building setbacks at 80' at all locations. 5) The City will send a revision letter to Dr. Engler with new calculations for land cash, stating there are 41, not 37 town homes. The current agreement states the City owes the district 3.13 acres of land cash @ $58,000/acre. 6) Point#10 - Easement language must be noted on the plat. A separate lot must be provided for City's trail and dedicated to the City. Ms. Brown stated that the trail and 5' on either side should be dedicated. 7) Point# 12—The backup SSA and the plat should be recorded at the same time. Landplanning comments by Mike Schoppe 1) Point#4 under preliminary plat—Mr. Schoppe stated the City wants to preserve the tree line (those 6' or more in diameter) on the west property line, which means that a 45' conservation easement prohibiting removal or damage to the trees should be included on the plat. Mr. Schoppe is asking the developer go 15' out from the baseline of the 6' and larger trunks to preserve the tree line. The ROW line from the street to the property line should equal 180', with a 30' front and 30' back easement. The street will need to be realigned because of the radius standard and lots 9-14 will be affected. Mr. Graff stated that if any trees are to be lost in the easement, language is need on the plat that would guarantee the developer be responsible for replacing them. The City anticipates there will only be a minimal number of interior lots that may be affected, suggesting to the Plan Commission that the developer has complied with the open space asked for by the City. 3 2) Point#2 under preliminary plat- Lots 8, 9 and 10 need to be adjusted to provide 80' lot widths at the building setbacks. 3) Point#6 under preliminary plat—Mr. Schoppe stated that easement language regarding the 30' path easement needs to be added to the plat. 4) Point#7 under preliminary plat - City Council is asking for 50' buffers for single family homes. The current easement is 40' for the commercial property and 10' individual. Mr. Schoppe suggested the landscape and utility easement, for planting, could overlap, and said the rear lot line would change. However, the easement lines could change to incorporate the 50' buffers. 5) Point# 5 under final engineering—Nine additional shade trees need to be added around the two detention basins west of lot 24. 6) A maintenance and management plan is needed for natural grasses planted in the storm water basins, for natural grasses planted above the water line. Triangle Investments will submit 4 copies of revised final plat and final engineering (incorporating the final landscaping)plans by June 7th. It will be rescheduled for Plan Council on June 24th and will go to the July 14th Plan Commission. Respectfully submitted, Annette Williams
