Please see the following comments from engineering and planning staff on the revised plan: 1. The fill being imported into Lot 2 appears to exceed 500 cubic yards. The applicant should provide fill calculations on the survey. If the material exceeds 500 cubic yards then a CUP will be required. 2. Further the grading as proposed appears to situate most of the fill material to the southern side of Lot 2, potentially impacting drainage and trees on Lot 2 as well as adjacent Lot 3. 3. The plan does not indicate the erosion control measures proposed or the measures that should be currently in place on the site. 4. The drainage swale on the southern property line of Lot 2 appears to direct run off toward the bluff. A mechanism to disperse and slow down water should be designed. 5. Retaining walls on Lot 1 do not have top and bottom of wall elevations shown as required by city survey standards. 6. Neither the grade of the driveway nor the topography on the adjacent property(50-feet) is depicted as required per city survey standards. Please make the above corrections to the survey and provide the additional information requested. A copy of the MCWD stockpile permit should be provided which allows the materials to remain on Lot 2. Please note, the project may have reached a level which will require approval of a conditional use permit by the City council. A staff determination will be made upon receipt of the material totals.
