Sections on sheets C2.2 and C2.3 show utilities located in common trenches which is a <br />good practice that needs to be administered during construction to ensure that common <br />trenching is adhered to and properly placed to provide adequate space for the landscaping. <br />Wherever possible the trenches should be held back from pavements and structiues not <br />less than 6 feet (preferably 8-10 feet) to provide more room for landscaping installation <br />and growth. <br />7. Aii 'valks should be constructed not less than 5 feet wide to meet handicap accessibility <br />guidelines. The walks shown as 3 feet wide should be widened to 5 feet to facilitate <br />access for everyone (the ADA 5 foot width is predominantly to facilitate wheel chair <br />movements, but also allows two people to pass more safely on a firm/cleared paved <br />surface and will more readily accommodate resident's and children's normal activities. <br />8. The townhome sections on C2.2 also show supports for the decks over the driveways. If <br />this is still under consideration, it needs to be addressed on the building elevations. <br />9. Section 1 on sheet C2.3 shows the slope between the first floor and walkout level at 3:1 <br />max. This is acceptable. Tenaced or low boulder walls should be used to reduce this <br />slope in locations where vegetation is difficult to establish or maintain, or to control <br />drainage or lessen the potential for erosion. <br />10. Section 2 on sheet C2.3 .shows parking adjacent to a retaining wall with a four foot drop­ <br />off. Adequate space must be provided between the road, vehicular exit space and the top <br />of any wall with a significant drop-off for safety. Enough space should be provided to <br />install a railing, hedge or barrier planting between any potentially walkabic area and the <br />top of any retaining wall over 3o inches high. <br />11. Section 2 on sheet C2.3 and detail 1 sheet C7.3 illustrate a concrete ribbon curb around the <br />cul-de-sac islands. The detail for this curb profile slopes away from the rain garden and <br />w ould trap water at the toe of the curb. If sloped toward the rain garden this profile may <br />trap sediment along the lip at the face of the curb. This detail should be reviewed with <br />engineering and carefully administered during constrviction. <br />12. Sections 2 on sheet C2.3 and E-E' on sheet L7.2 show pedestrians walking in the rain <br />garden area. What walking surfaces will be used in the northwest Lane rain garden <br />island? <br />1 3. Detail 5 Boulder Retaiiung Wall on Sheet C3.2. llie use of low and/or terraced natural <br />boulder walls in lieu of modular concrete or timbers will result in a much more natural and <br />attractive development. These walls require e.xperienced and skilled artisans to achieve <br />the best results. The detail notes that the largest stones shall be placed at the bottom of the <br />wall. The walls will function better and look more natural if they are constructed without a <br />strictly graduated tiered look. This can be accomplished by creating walls with a more <br />/601/1*02-2 'S9 2S40 Dahlstrom'Lincffbrm Development "StoneBay Page 4
