The following corrections must be addressed or materials submitted before review can continue: 1. Geotech report: The geotech report from South Fork Geosciences dated August 7, 2015 states that there are no critical areas on the site, which is in contrast from the critical area determination for the parcel issued January 29, 2015 (CRA20140120). The determination states: Your property is located on a hillside with a western facing slope. This slope varies between areas near level, around the house, to areas on your property where the slope exceeds 40% according to City LiDAR data. Due to the degree of the slope on and adjacent to the your property, it was found that the site contains slopes that are steep enough to be considered both an Erosion Hazard Area (over 15% slope) and a Landslide Hazard Area (over 40% slope). Your property also includes the Alderwood and Alderwood-Everett USDA soil series types. Both of these soil series types are listed in section 23.80.020 ECDC which identifies soil series that have characteristics leading to possible severe to very severe erosion occurrences. Please submit an updated report which addresses the presence of these possible hazards on the site relative to the proposed development. Reference can be made to the 'Limited Report Requirements for Stable Erosion Hazard Areas' in ECDC 23.80.050.G if that is applicable in this instance; otherwise, submit a report prepared in accordance with ECDC 23.80.050 and 23.40.090 which addressed 23.80.060, 23.80.070 and 2. Vegetation plan: Please revise the vegetation plan to show the retention line (bubbled outline on Lots A & B) to match the clearing limits shown on the Sheet 2 (SWPPP) and label the 'trees to be removed' as appropriate. Also, please indicate the square footage of retained native vegetated area on each lot (either on the updated plan or on an updated cover letter).
