<br />The private drive shown at the north end lines up with 8'h Street directly across <br />Jackson Avenue, Currently, the undeveloped property to the north owned by Rivers <br />Christian Academy has a driveway access onto J ackson Avenue immediately north of <br />. the Jackson Street Villas site. Jackson Street Villas shows a combined access onto <br />J ackson Avenue servicing both properties and lining up with 8'" Street. <br /> <br />. It is unclear whether the common area outside of the 76 building pads will all be <br />encompassed with drainage and utility easements. If not, drainage and utility <br />easements will need to be provided for the public sanitary sewer and water systems, <br />along with the storm sewer and ponding areas. If the entire common area is to be <br />deemed drainage and utility easement, this will accomplish the same thing. <br />. Jackson Avenue is currently striped with two lanes; one north and one south, and <br />two parking lanes, although the west side of Jackson Avenue adjacent to the Jackson <br />Street Villas is currently signed "no parking". The requested rezoning to PUD and <br />construction of 76 townhomes will provide significant traffic on J ackson Avenue <br />wanting make left turns into the development. A left-turning vehicle will back traffic <br />up with a one-lane roadway since it is illegal to pass a left-turning vehicle by using a <br />striping parking lane. Therefore, we would recommend that the Jackson Street Villas <br />project be required to pay $15,000 for the re-striping of Jackson Avenue to a three- <br />lane configuration with a center left turn lane and no parking lanes. This will allow <br />left-turning vehicles to get out of traffic and wait for a safe opportunity to make their <br />left turn while still allowing through-traffic to move freely northbound on Jackson <br />Avenue. <br /> <br />B. Preliminary Grading Plan <br /> <br />. The pond grading appears to be shown with 3: 1 slopes. The City design standards <br />require a maximum slope of 4:1, both above and below the water level of the pond. <br />. The preliminary grading plan should include information such as invert elevations on <br />the flared-end sections and rim elevations on the catch basins. <br />. The site has very little open space or areas to plow snow from the streets. Where <br />will snow in heavy snowfalls be stored? It should be made clear that it is not <br />permined to deposit excess snow in the wetland created at the northwest. comer of <br />the site. Snow may be stockpiled in the ponding area. <br />. The following lots appear to have very flat driveways: 34,43,47,48,63,66. <br />. The following lots have rear yards that are flat or sloped towards the building: 9, 19, <br />15,16. <br />. The emergency overflow between Lot 51 and Lot 52 should be labeled in an <br />elevation given. <br />. Show existing spot elevations on the existing sidewalk and curb or bituminous to the <br />east, south and north of the site to ensure that the grading fits with the surrounding <br />property. <br />. Since the streets are considered private, so will the storm sewer system along with <br />the ponding area. <br /> <br />S:\PLANNING\Case Files\2004\P 04-16 Jackson Ave Villas\10 504 Engineers memo.doc <br />
