I appreciate you taking the time to share your frustration with us,and your suggestions to improving our processes. Our goal,with every building permit, is to issue the permit as rapidly as possible,without sacrificing the thoroughness of our review. This review is a service to ensure that your project is consistent with applicable zoning and building codes and to avoid costly alterations in the field. For instance, our engineer recently noted your landscape plan,the retaining wall site plan,and the grading plan do not match. The grading plan depicts two long retaining walls. The landscape plan depicts two short walls. The Site plan from Civil Design depicts one long wall and two short walls. All three plans should reflect the same retaining walls. This discrepancy leads to confusion in the field, may require alterations of the grade, and could require you to purchase too much, or not enough materials. Please address in revised drawings. Regarding the retaining walls,the choice to install one is yours alone, however, if one is to be installed over 4 feet in height, it requires engineering. This is for your protection and a requirement of the state building code. The rain garden on your property resulted from the platting process,finalized in October after your builder submitted the building permit application in September. I trust the developer informed you of the requirement. The building plans are being reviewed by the building official,the city engineer has reviewed your plans and provided the comments above. The review of the rain garden has been completed,and the following comments will be included in the final permit: 1. The rain garden has been adequately sized to maintain proposed peak runoff rates below existing conditions and retain a volume on site equal to 1"over the new impervious surfaces. 2. The rain garden should not be constructed until the upstream areas have been permanently stabilized. 3. The installation of the rain garden should be inspected by the City to ensure it is constructed as proposed. �
