Pleasureland RV - Site Plan September 24, 2003 Revised: October 10, 2003 Page 3 of 4 Lighting: The lighting plan for the development consists of thirty-six 40-foot-high standard mounted lights and nine wall-mounted units. The standard mounted lights are a combination of 28 single-fixture units and eight back-to-back double units. The commercial lighting code for this district requires that bulbs emitting more than 3000 Lumens, which includes all 45 units, must be directed such that the bulb is not visible from off the subject property. The impact of the proposed development's lighting plan On surrounding properties was an item of discussion at the Planning Commission meeting. The applicant has submitted a revised lighting plan; staff will be prepared to comment on the lighting plan at the City Council meeting. Drainage and Grading: At the present time, discharge from the site, the street, and some adjacent vacant property flows overland to a point in the south curb line of Riverdale Drive, which is approximately 240 feet west of Alpaca Street. This low point discharges through a bituminous spillway into a grass-lined swale which flows approxim,ately. 300 feet south into a low area on the property located at 14322 Alp,aca Street, which is encumbered with a drainage and utility easement. The proposed grading and drainage plans anticipate directing the parking lot and building runoff overland from west to east into two ponds. The pond located on the southeast corner of the northern portion of the development is 140 feet by 50 feet and contains 0.56 acre feet. This pond discharges through a storm sewer to a second pond which is located along the southern boundary of the southern half of the development. This pond is 50 to 105 feet in width and is 560 feet long. This southerly pond also accepts runoff from the southern half of the development. The ponding system is designed to hold runoff from a 100-year storm event falling on the development site. Any flows in excess of this amount would be discharged into the roadside ditch on the west side of Alpaca Drive. This ditch flows south and west and eventually discharges to the Mississippi River. Following up on concerns raised by the neighbor at 14322 Alpaca Street, staff did additional investigation and learned that discharge from this pond may inundate property outside the street right-of-way and 10-thor drainage easement at 14290 Alpaca Street. Additionally it was learned that the property .on the east side of Alpaca at 14401 Alpaca Street has had past problems with drainage, causing backups in the septic system. Re-ditching the east side of the roadway could alleviate this problem. The extent of the reqtiired re-ditching is not known at the time of this writing. A report on the extent of re-ditching at its associated cots may be available by the time of the Council meeting. The grading plan was revised following the Planning Commission meeting. The Fading plan proposes side slopes along the ponding area of 3:1, which is steeper that the City maximum allowable of 4:1. The plan should be revised accordingly. This development requires, and has received, a permit from the Lower Rum River Water Management Organization. Access: The site proposes four accesses onto Riverdale Drive, two from the north sales l°t and two from the south sales lot. The access into the service bay is proposed to be 108 feet wide, to be expanded to 212 feet when the additional service bays are constructed. This width of driveway
