These <br />are primarily items that were not dealt with in depth at the Concept Plan stage, and for which a <br />greater level of detail now has been provided at the Development Plan stage of the review process. <br />Various City consultants and staff have reviewed the plans and have made verbal or written <br />comments, summarized below: <br />I.Wally Case of DSU, Inc. has reviewed the Final Development Plans, specifically the <br />landscape plans. He also was asked to comment on the scale and massing of buildings, open <br />space, circulation, etc. While his written comments will not be available for another week <br />or two. Case did verbally provide his comments to staff in a phone conversation on October <br />1 7. He indicated that the proposed landscape plan is very good and substantially exceeds the <br />minimum requirements of the RPUD District. Case had a number of suggestions and <br />comments about various aspects of the plan. The following is a brief summary of his <br />comments: <br />l^andscaping: <br />- In general, the landscaping/grading of the site incorporates many retaining walls. Based <br />on the cover sheet key, most of these will be modular block walls, although the detail <br />suggests they will be mostly boulder walls. Which is it, or is there a mix that is not clearly <br />apparent? Whuc is the type of stone to be used in the boulder walls - Limestone? Igneous <br />boulders? Most of the walls appear to be less than 4* in height; those over 4* will need to be <br />engineered. Where boulder walls arc to be used, the detail suggests a tiering by boulder size, <br />biggest on the bottom, smallest on top. This is conceptually correct, but an e.xperienced <br />boulder wall contractor should be used to ensure attractive, high quality, stable wall systems <br />that don’t look “layered”. <br />The boulder wall along the NW comer of the cast Lofts building leaves no pedestrian <br />access above the boulder wall... could this be tweaked, and is it a potential fire access issue? <br />- In general the landscaping plan is excellent, incorporating suitable tree and plant species <br />and seed mixes. The proposed tree sizes are appropriate. Case has some suggestions <br />regarding a few tree or plant species he would rather avoid, and he might suggest more use <br />of native species, but overall the planting plan is very well done. He suggests that pH <br />readings be taken before planting so that certain tree species might if necessary be traded out <br />for those most tolerant to actual site conditions... <br />- Note that the shrub beds are not edged, which leads to a softer look but perhaps unkempt <br />until plantings mature.
