<br />Project Description
<br />The 4.237 acre project site is located on the east side of US Highway 61 at 1461h Street North. The site is
<br />directly adjacent to Egg Lake. The site has been cleared of all buildings as a precursor for
<br />redevelopment. Prior to clearing the site approximately 44% was covered with impervious surfaces.
<br />The proposed development includes a 5,000 square feet (sf) restaurant, 3,870 sf event center and three
<br />retail buildings totaling 10,100 sf, along with associated parking and other site amenities. This report
<br />only addresses the first 2 phases of the development which includes the restaurant, event center and
<br />Spgsoximately 60 stalls. The stormwater solution for the first phase will be utilized for the future phases.
<br />Topsoil over apparent undocumented fill soils were encountered extending to depths ranging from
<br />approximately 2.0 to 9.0 feet below the existing ground surface. The soils encountered beneath the
<br />undocumented fill soils generally consisted of poorly graded sand (SP), poorly graded sand with silt (SP-
<br />SM), and silty sand (SM) soils. The undocumented fill soils encountered in the soil borings are not
<br />considered suitable for direct support of the foundations and slabs.
<br />Receiving Waters
<br />The site is adjacent to Egg Lake

<br />Stormwater Management System Overview
<br />See Stormwater Management Plan incorporated herein by reference for details on system design, flow
<br />rates and volumes and system capacities. In general to achieve rate and volume control it is proposed to
<br />construct the entire parking lot utilizing porous bituminous pavement. The grading plan shows a typical
<br />grade of 0.5% on the pavement which will facilitate 100% infiltration of rainfall events up to the 10 year
<br />24 hour storm and surface overflow for the 100 year event. The portion of the building with a flat roof
<br />will drain via an internal drain system and discharge onto turfed areas on the north and east sides of the
<br />building.
<br />See Operations and Maintenance Manual for post construction system maintenance requirements.
<br />Erosion Prevention, Measures - General

<br />necessary to protect these areas before construction begins on the site.
<br />3. All drainage ditches and/or swales shall have temporary or permanent stabilization within 24
<br />hours of connecting to a surface water or 24 hours after construction activity in the ditch/swale
<br />has temporarily or permanently ceased.
<br />4. All pipe outlets shall have temporary or permanent energy dissipation within 24 hours of
<br />connecting to a surface water.
<br />5. All exposed soils shall be stabilized as soon as possible to limit soil erosion. In no case shall un-
<br />worked areas, including stock piles, have exposed soils for more than 14 days without providing
<br />temporary or permanent stabilization. (7 days for projects with a receiving water that is
<br />impaired or special)

<br />appropriate BMP's, to effectively remove sediment.
<br />3. All discharge points shall be protected from erosion and scour.
<br />4. Discharge water shall be dispersed over an effective energy dissipation measure.
<br />5. All water from dewatering shall be discharged in a manner that does not cause nuisance
<br />conditions, erosion, or inundation of wetlands. Water shall not be discharged to adjacent
<br />residential properties. It must be discharged to the public street.
