14-4-115 LOT ACCESS AND SITE LAYOUT

A. Each proposal to construct a primary structure more than one hundred fifty (150) feet from a public street shall be reviewed and approved by the Administrative Committee and Fire Marshall prior to receiving a building permit. Furthermore, all proposals must adhere to Section 503 of the International Fire Code, as adopted by the South Davis Metro Fire Agency and all other criteria as set forth below. All of the following must be met before the Administrative Committee may grant approval: 1. Surface. An all-weather surface capable of supporting the imposed load of fire apparatus shall be provided. If constructed of asphalt, the access road or driveway shall be a minimum of two and one-half (2 1/2) inches of asphalt over a minimum of six (6) inches of compacted road base. If constructed of concrete, the access road or driveway shall have a minimum of five (5) inches of concrete over a compacted road base. The access road or driveway shall be maintained by the property owner or possessor of the premises in good condition and repair and with adequate snow removal so as to provide free and uninhibited access by emergency service vehicles. 2. The access road or driveway shall be a minimum of twenty (20) feet wide. Where such roadway is adjacent to required fire hydrants, the width shall be a minimum of twenty-six (26) feet within twenty (20) feet in either direction from the hydrant. Such required widths shall be unobstructed, including parking of vehicles, and shall have a minimum vertical clearance of thirteen (13) feet six (6) inches. 3. A turn-around shall be provided at the end of the access road or driveway in accordance with the standards and specifications of Article 10 of the International Fire Code and in accordance with the minimum requirements of Figure 4-1. The minimum turning radii for all turns and/or curves shall conform to the forty-five (45) foot radius single unit truck or bus contemplated in Figure 4-4. If access roads are not looped, then the provided dead end access road shall meet the requirements in Figure 4-2. 4. An access road or driveway shall be extended to within one hundred fifty (150) feet of all portions of the exterior walls of the first story of any building. 5. The maximum grade for access roads or driveways shall not exceed fifteen (15) percent at any point as measured along the centerline of the access road or driveway. 6. Each property owner shall identify and mark fire lanes to the satisfaction and approval of the Fire Chief. Signs shall be posted near the entrances of access roadways and driveways. Spacing and placing of signs shall be subject to the approval of the Fire Chief. Signs shall be a minimum of twelve (12) inches by eighteen (18) inches in two and one-half (2.5) inch block lettering with one-half (.5) inch stroke on a contrasting background. Signs shall read "No Parking - Fire Department Access Road.” 7. The property owner or possessor of the premises shall establish the base grade of the access road or driveway before the water system is installed. The property owner or possessor shall clear the right-of-way for the water system and establish the proposed fire hydrant locations and grades by use of an offset stake. The City shall install the water system and set the fire hydrant to the grade established by the owner. If there are any changes to the access road or driveway or right-of-way areas which do not allow for a minimum of forty-two (42) inches of cover over the water line or not more than four (4) inch vertical difference between the flange of the fire hydrant and the finished surface of the access road or driveway, the owner shall be responsible for all expenses associated with the relocation or adjustment to the water system. No building lot shall be allowed or approved where the static water pressure from the City water system serving the proposed lot or lots is less than forty (40) pounds per square inch. 8. Fire Hydrants. A fire hydrant shall be installed by Bountiful City at the expense of the property owner and shall be connected by a six (6) inch water line from the water main. The hydrant shall be located in accordance with Article 10 of the International Fire Code. Fire hydrants shall be located on all required access roads or driveways as required by City Code and shall be located within five (5) feet of the required access road or driveway. If, in the opinion of the Fire Chief, fire hydrants are vulnerable to vehicular damage, appropriate crash posts shall be required. No obstruction shall exist within a three (3) feet working area of each fire hydrant. Required crash posts shall be a four (4) inch concrete filled pipe, having a minimum of three (3) feet in height above grade, with two (2) feet of pipe below grade set in concrete. Hydrant shut-off valves shall be located no closer than five (5) feet from the hydrant and no further than twenty (20) feet. 9. Easements. The fire hydrant, water line, and access road or driveway shall be located within a public utility easement of at least twenty (20) feet in width such that emergency and utility service vehicles and personnel have unimpeded access to the improvements (Figure 4-3). 10. All of the required improvements shall be installed at the lot or property owner's expense. 11. As an alternative to the access requirements described above, the Fire Marshall may approve the installation of a pressurized interior fire protection sprinkling system that complies with the minimum standards of the IRC and/or IBC, and that receives the Fire Marshall’s approval. B. All new residential structures shall comply with the requirements of the IBC for foundation elevation on graded sites (1805.3.4 and 1805.3.5). For most approved lots, the “approved drainage facility” is the street R.O.W. On these sites, the finished grading shall direct runoff from the front yard setback to the street R.O.W. by means of the driveway or front yard grading, or as approved by the City Engineer. Driveway slopes shall have a minimum slope of two percent (2%), and a maximum slope of fifteen percent (15%), as measured along the centerline of the driveway. C. Downhill or reverse grade driveways must be reviewed and approved by the City Engineer. Approvals will be considered based on proximity of the lot to storm drain facilities or natural draining features such as creeks, swales or other features that convey runoff water directly to the storm drain system. Approval shall be conditional upon inclusion of the following requirements: 1. The driveway shall provide a minimum length of ten (10) feet of positive slope (two percent (2%) minimum) to the street R.O.W. 2. The maximum grade of the driveway shall be seven percent (7%). 3. The approved site plan shall include any additions or modifications to the existing storm drain system necessary to prevent erosion or impact to adjacent properties, or impact to the storm drain system. 4. Other requirements as determined by the City Engineer based on conditions specific to the property.
