Mr. Steve Ach May 18, 1995 a Page Four of the building home sites with the natural topography of the azea. This should lend itself. to the ability to save many trees in the rear of each property. We would also note that, in our meetings with the Developer, he has indicated that the grading process will individually mazk trees in the fronts of lots that can be saved. In areas of little or no cut or fill activities, large specimen trees would be noted for saving, even ones that would require small retaining walls'. or other measures to protect them and blend them into the fmal product. ^ The City ordinance sets the maximum street grade at 8%. There are several locations, specifically in the northern part of this development, where proposed street grades exceed this maximum slope. However, there aze other items that we believe the City should balance in reviewing these areas. Those would be the layout of the lot relative to the natural topography and the vegetation. We can certainly envision a situation where an 8% street grade could be exceeded if there are benefits such as saving substantial stands of significant trees. In reviewing such an issue, we would look at the amount of traffic, the ability to provide a flat area for stopping, the ability for the Street Department to keep the azea clear of ice and snow during the . winter months, and the site distances provided through these types of vertical curves. In order to make a final determination on the specific issues relative to this plat, we would recommend that the Developer supply additional information such as street profiles, cross-sections, and other information which would support his position for asking for deviation from the maximum street grade. ^ No storm drainage calculations have been provided at this point in time. The concept of storm drainage laid out on the Preliminary Grading Plan provides for collection of runoff with a small diameter storm sewer system and depositing it into various lowlands. These ponding areas would have no outlet; therefore, they will need to be designed for a worse case scenario. Also, sedimentation ponds will need to be provided prior to any areas proposed to discharge to desugnated wetlands. ^ There are several areas on !the Grading Plan where contours are either missing or mislabeled. These need to be corrected in future submittals. ^ As this project moves forward and more specific drawings are provided for the first phase, we would recammend that the City require the Grading and Development Plans be prepared at a lazger scale. It is very difficult to do . a detailed review of this type of area at such a small scale. 230/758-1802.may
