Matthews Design 2075 Las Palmas Dr. - Carlsbad, CA 92009-1 576 - (61 9) 438-11 61 - FAX (61 9) 438-0894 @ LIST OF ITEMS NEED TO COMPLETE APPLICATION No. HDP 96-06 - Wilson Residence 1. 2. 3. 4. 5. 6. 7. Please provide a roof plan to assist in accurate building height measurements. Please provide the missing wall height information indicated on the enclosed checkprint. According to the attached submittal checklist, the slope analysis is supposed to be drawn to the same scale as the site plan and should include the following information: location, slope and width of driveway, building setbacks, location of any retaining walls and drainage systems. Slope profiles are supposed to be drawn in accordance with section 21.95.020(b) of the Carlsbad Municipal Code, copy attached. The slope profiles need to be straight cross section lines, two parallel and one roughly perpendicular. The cross sections must show existing and proposed topography, structures and improvements and be drawn in the areas of most intense development. Please provide the area extent of grading and proposed volumes of cut and fill, indicating if import or export of material. is required. Please submit a profile for the proposed 24% grade driveway. Please label the block wall along the northern property line as ‘existing’. ISSUES OF CONCERN Planning: 1. Based upon the building elevations, cross sections and proposed grading scheme, it appears that the proposed house is well over 30 feet in height and contains three stories. The maximum building height in the R-1-15 zone is 30 feet with two stories maximum. Enclosed are the applicable portions of the Zoning Ordinance. Please either redesign the house or show how the house height complies with the zoning requirements. 2. According to the Zoning Ordinance, the maximum wall height in the front yard is three and one half (3.5) feet and in the side yard is six (6) feet. The proposed grading scheme shows walls exceeding these maximums. Please also note that the infill grading regulations might further limit the wall height. There is also a design issue with the up to nine (9) foot high exposed retaining wall on the lower end of the project. Please lower walls to conform with these provisions. . 3. Areas with inclination greater than 40% are considered undevelopable. The lower end of the proposed house and yard encroach into slopes over 40% inclination. Please retract development from these areas. 4. No comments on the conformity of grading volumes per developed acre can be made since no grading volumes were provided. The maximum volume of grading is 8,000 cubic yards per developed acre. Engineering: 1. The proposed project is insensitive to infill grading as identified in section 1 1.06.032 of the Carlsbad Municipal Code, copy attached. 2. The proposed 24% grade driveway is considered too steep. A maximum grade of 15% is allowed by City Standards. 3. Drainage from top of slope and generally onsite has not been addressed. 4. Based upon initial evaluation, a grading permit will likely be needed. A grading permit may be processed concurrently with the Hillside Development Permit however, since the site design may change through the Hillside Development review, you may risk having to re-engineering the grading construction drawings.
