've reviewed the plans you delivered to the City last week. I'll need the following additional information before I can complete my review:
1. Building Height. Our maximum building height is measured from the average elevation of existing grade. For the proposed residence, your plans show the existing grade at -0' 8" (sheet A3.0). If this is the average elevation, the plans or supporting documents need to indicate how this was determined. Our ordinance establishes a method for calculating existing grade: see Cannon Beach Municipal Code (CBMC) 17.04.275, "Ground level grade means the average elevation of the existing ground elevation before construction at the corner of all walls of a building. Where a building has more than four corners, the average elevation shall be measured from the four corners of a square or rectangle that encloses the foundation of the proposed structure."
2. Proposed Garage. Your site plan shows a proposed detached garage to the south of the proposed residence; but your application materials do not include any construction plans for this garage; nor is there a building height calculation for the garage; nor is the garage included in your lot coverage or FAR calculations. Additionally, it appears that the proposed garage location encroaches into the wetland buffer area. I can't approve the proposed garage until you address these issues.
3. Lot Coverage. You provided lot coverage calculations for the proposed residence on tax lot 900, but the proposed driveway extends onto the lot to the north (672 N Hemlock, tax lot 904). The driveway increases lot coverage on this lot, so I'll need an updated lot coverage worksheet for 672 N Hemlock, reflecting the new driveway.
4. Off-Street Parking. You've shown two off-street parking spaces on the site plan. Our code's minimum size for an off-street parking space is 9' x 18'. The two spaces shown on your site plan appear to be slightly smaller than required; however, there is sufficient room for full-sized spaces. Please modify your site plan to show two full-sized off-street parking spaces.
5. Stormwater Management. The submitted plans lack stormwater information. The plans will need to comply with the stormwater management requirements in CBMC 17.43.050.J. Please show on the plans how you will handle stormwater runoff from the proposed driveway and residence.
6. Exterior Lighting. If I read it correctly, your plan shows exterior lighting (sheet E.10). This lighting will need to comply with the standards in CBMC 17.90.110, limiting exterior residential lighting to 1,260 lumens per fully-shielded fixture, with some exceptions. Your plans need to show compliance with these requirements.
7. Wetland Fill. The DSL-approved delineation map contains a note added by DSL staff that reads, in part: "...approximately 23 cubic yards of riprap was placed in wetlands when the riprap wall was built." I don't know when the riprap wall was built, but unless it was permitted and built prior to the adoption of the wetlands overlay zone, in 1994, you'll have to either provide evidence that the fill complies with the zone's requirements (CBMC 17.43), or remove the fill material from the wetland.
I have not yet reviewed these plans with the Fire District, Building Official, or Public Works Department; their review may identify other areas where additional information is required. Please contact me if you have any questions on these items.
