LOT B IS OWNED BY MARGOLIS LAND COMPANY, 410 STRONG STREET, BRIGHTON, CO 80601. THE SUBJECT PROPERTY IS CURRENTLY UNDEVELOPED FARM LAND WITH A FAIRLY CONTINUOUS 0.5%± SLOPE TO THE NORTH. THIS SITE IS A PART OF THE URBANIZING DRAINAGE AREA. THE ONSITE SOILS ACCORDING TO A REPORT BY HIGH PLAINS ENGINEERING CONSIST OF I TO 2 FOOT OF SM SANDY SILT, UNDERLAIN WITH GP GRAVEL. A PIPE LINE VALVE EASEMENT IS LOCATED IN THE NORTHEAST CORNER OF THIS PROPERTY. THERE IS AN EXISTING ROAD SIDE SWALE LOCATED ALONG THE NORTHERN BOUNDARY OF THE SITE ALONG NEW ENERGY DRIVE (CR 4). THERE ARE NO MAJOR OPEN CHANNELS, LAKES AND/OR STREAMS WITHIN THE BOUNDARY OF THE SITE. DEVELOPMENT OF THE SUBJECT PROPERTY WILL BE IN A SINGLE PHASE. B. HISTORIC DRAINAGE BASINS AND SUB -BASINS MAJOR BASIN DESCRIPTION THE SITE LIES WITHIN THE UNSHADED ZONE C AS DETERMINED BY FEMA FLOOD INSURANCE RATE MAP NO. 08123 C (PANEL 2120E), EFFECTIVE JANUARY 20, 2016. FEMA DEFINES UNSHADED ZONE C AREAS AS MINIMAL RISK LOCALITIES THAT LIE OUTSIDE THE 1% AND 0.2% ANNUAL CHANCE OF A FLOOD. NO BASE FLOOD ELEVATIONS (BEES) HAVE BEEN ESTABLISHED FOR THESE ZONES.

DEVELOPED RUNOFF (24HR, 100YR RECURRENT STORM EVENT) WILL BE RETAINED WITHIN RETENTION PONDS. C. DRAINAGE DESIGN CRITERIA REGULATIONS THE PROPOSED DRAINAGE DESIGN COMPLIES WITH THE UDFCD CRITERIA MANUAL (CURRENT VERSION) AND THE WELD COUNTY CODE. DEVELOPMENT CRITERIA REFERENCE AND CONSTRAINTS BASED ON EXISTING GRADE ELEVATIONS AT THE PERIMETER OF THE SUBJECT P ROPERTY, RUNOFF GENERATED BY THIS PROJECT, UNDER BOTH HISTORIC AND PROPOSED CONDITIONS, MAY ENTER THE RETENTION FACILITIES P LANNED BY THESE DEVELOPMENTS HYDROLOGICAL CRITERIA THE RATIONAL METHOD WAS UTILIZED IN ESTIMATING THE 100 YEAR RECURRENT STORM PEAK RATES OF RUNOFF FOR THE MAJOR STORM EVENT. THE 24 HOUR, 100- YEAR DESIGN POINT RAINFALL DEPTH WAS OBTAINED FROM FIGURE RA► -6: RAINFALL DEPTH -DURATION -FREQUENTLY OF THE UDFCD CRITERIA MANUAL, VOLUME 1. D. DRAINAGE FACILITY DESIGN GENERAL CONCEPT THE PROPOSED STORM WATER DESIGN WILL MAINTAIN THE HISTORIC DRAINAGE DISCHARGE FROM THE SITE. THE RUNOFF FROM THE DEVELOPED SITE WILL BE COLLECTED VIAA NETWORK OF PAVEMENT (RECYCLED ASPHALT PAVEMENT, RAP) SHEET FLOW AND SMALL DRAINAGE SWALES AND WILL BE DIRECTED NORTH TOWARD THE P ROPOSED RETENTION POND. THE STORM WATER MANAGEMENT/RETENTION PONDS HAVE NO OUTLET SPECIFIC DETAILS HISTORIC BASIN. THE SITE WILL MAINTAIN RETENTION PONDS. THE PONDS WILL HAVE A CAPACITY TO HOLD 1 I�2 TIMES THE 24 HOUR 100 YR STORM. THE SITE CONTAINS 10.01 ACRES AND IS COMPRISED OF UNDEVELOPED LAND WITH NATIVE GRASS COVER. STORM WATER MANAGEMENT FACILITY DESIGN THE 24 HOUR, 100 -YEAR RAINFALL IS 3.4 INCHES ACCORDING TO FIGURE 7-9 DENVER REGIONAL COUNCIL OF GOVERNMENTS. THE DESIGN WAS MADE USING THE FORMULA► 1 .5 X THE 24 HR , 1 06YR STORM THE SITE AREA = RETENTION REQUIRED. THE PROPOSED POND WILL HAVE A CAPACITY OF 3A INCHES X 1.5 X 10.1 ACRES X 48560= 186,981 CU .FT. WITH 1 FOOT OF FREE BOARD. PERK RATE FOR THE GRAVEL IS 10 MINUTES PER INCH OR LESS. 10 MINUTES PER INCH = 0.5 FT. / HR. AREA OF POND BOTTOMS = 37,747 SQ. FT. 0.5 X 37,747 = 18,873 CU. FT. / HR. 186,981 CU. FT. / 18,873 CU. FT. /R = 10 HOURS. DEVELOPMED IMPERVIOUSNESS GRASS AREAS 1.45 ACRES X 2 = 2.9 RECYCLED ASPHALT 8.65 ACRES X 40= 346 346 + 2.9 / 10.1 ACRES = 34.5 MAINTENANCE PLAN FOR RETENTION PONDS PONDS WILL BE INSPECTED WEEKLY BY OWNER AND WILL ALSO BE INSPECTED DURING AND AFTER ANY SEVERE WEATHER CONDITIONS.
