16 <br /> <br />• Security or service lighting should be limited in coverage area and designed to <br />reduce glare. <br /> <br />Wall mounted down lit lighting is proposed on the exterior of the senior housing complex <br />and clubhouse. <br /> <br />Stormwater Management <br /> <br />• Stormwater management design must incorporate filtration and infiltration elements. <br />This could include such features as rain gardens, swales, dry creeks, infiltration <br />chambers, and other ecologically based methods along with more traditional ponds <br />and pipes. <br /> <br />• Stormwater management ponds, if used, should be designed to be a site amenity, <br />including appropriate landscape elements. <br /> <br />Per the Storm Water Management Report prepared by Anderson-Johnson Associates <br />dated January 10, 2019, water quality treatment is accomplished at the single stormwater <br />treatment pond. True infiltration was considered during the design phase, but several <br />factors contributed to not pursuing infiltration practices. First, shallow groundwater exists <br />on site. According to the soil borings, groundwater is in the 895 to 897 elevation range. A <br />majority of the low points are around elevation 905 with one parking lot having a low <br />point of about 902.5. This would mean the surface of an infiltration area would need to be <br />at elevation 900 - 901 for effective drainage to occur. Additionally, the site has been <br />maximized and there is not adequate space for effective infiltration practices. <br /> <br />Instead, a stormwater pond has been constructed. The stormwater pond, in addition to <br />providing rate control, has been sized to provide adequate dead storage below the normal <br />water level to meet water quality requirements. Finally, an irrigation pumping station will <br />be constructed at the stormwater pond to draw water from the pond to irrigate the <br />surrounding areas. <br /> <br />The clubhouse has been strategically located adjacent to the landscaped stormwater pond <br />as a site amenity. <br /> <br />Additional Site Plan Review <br /> <br />Building Footprints and Floor Areas <br /> <br />A summary of the building footprints and square footages is as follows: <br /> <br />Building Footprint Total Floor Area <br />Cottage Homes 1,400 sf 1,400 sf <br />Clubhouse 3,400 sf 4,609 sf <br />Senior Living Campus 128,113 sf 292,462 sf
