A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Erosion Factors Soil Erosion Factors are soil properties and interpretations used in evaluating the soil for potential erosion. Example soil erosion factors can include K factor for the whole soil or on a rock free basis, T factor, wind erodibility group and wind erodibility index. K Factor, Whole Soil (K Factor) Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. 16 Custom Soil Resource Report Frequency of ponding: None Calcium carbonate, maximum in profile: 15 percent Salinity, maximum in profile: Nonsaline to very slightly saline (0.0 to 2.0 mmhos/cm) Sodium adsorption ratio, maximum in profile: 5.0 Available water storage in profile: Very high (about 18.0 inches) Interpretive groups Land capability classification (irrigated): 1 Land capability classification (nonirrigated): 3c Hydrologic Soil Group: B Ecological site: Overflow (R049XY036CO) Hydric soil rating: No Minor Components Caruso Percent of map unit: 7 percent Hydric soil rating: No Paoli Percent of map unit: 4 percent Hydric soil rating: No Fluvaquentic haplustolls Percent of map unit: 4 percent Landform: Terraces Hydric soil rating: Yes 15 Custom Soil Resource Report Minor Components Aquolls Percent of map unit: 5 percent Landform: Swales Hydric soil rating: Yes Poudre Percent of map unit. 5 percent Hydric soil rating: No 105—Table Mountain loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol: jpty Elevation: 4,800 to 5,600 feet Mean annual precipitation: 13 to 15 inches Mean annual air temperature: 48 to 50 degrees F Frost -free period. 135 to 150 days Farmland classification: Prime farmland if irrigated Map Unit Composition Table mountain and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Map Unit Legend Larlmer County Area, Colorado (CO644) Map Unit Symbol Map Unit Name Acres in AOI Percent of A01 64 Loveland clay loam, 0 to 1 4.4 97.1 % percent slopes 105 Table Mountain loam, 0 to 1 0.1 2.9% percent slopes Totals for Area of Interest 4.5 100.0% Map Unit Descriptions The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the 11 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of smal l IA01) pA Spoil Area The soil surveys that comprise your AOI were mapped at Area of Interest (AOI) Spot Stony Sp 1:24,000.

It is required by the permit for Stormwater Discharges associated with Construction Activities that final stabilization will be achieved when all ground disturbing activities are completed and a uniform vegetative cover has been established with an individual plant density of at least 70% pre -disturbance level, or equivalent permanent, physical erosion reduction methods have been employed. Note to SWMP Administrator: The removal of temporary BMPs must not take place until the site has completed ground disturbing activities and a uniform vegetative cover has been established in the designated re -vegetation areas with the individual plant density of 70% pre -disturbance levels. Note: Landscaping shall be installed per the landscape plan. Site Specific Re -Vegetation Plan The re -vegetation plan for the project consists of landscaping and seeding and mulching (if necessary) upon completion of all construction activities. All disturbed areas not covered by gravel paving or the building pad shall be seeded & mulched or landscaped per the enclosed erosion control plan and accompanying notes. The project will utilize sod, ornamental grasses, native plantings, rock mulch, trees, and shrubs as a final stabilization method of all disturbed areas. Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to oversee seeding operations to ensure proper application for expected growth. 4.1.G LWS Post Construction BMPs or permanent structures that will remain on site include permanent landscaping. An Operating and Maintenance manual may be developed in accordance to the CDPHE requirements and can thus be referenced for future maintenance procedures. Phasing of the stabilization plan, changes in inspection frequency, and closing of the CDPS permit shall be documented. 18 O ,OLSSON (r, ASSOCIATES at the River Hotel Phasing and Sequencing Spirit at the River Hotel, SWMP 017-0150 The following table lists the phases of construction for the Project and the implementation of structural and non-structural BMPs associated with the particular phase of construction: Phases of Constructiom Implemented BM'P(s) for PhanAaction Date of BMP Installation Silt Fence (SF) Installation of temporary erosion Inlet Protection (IP) Vehicle Tracking Control (VTC) controls Concrete Washout Area (CWA) Stabilized Sta in Area SSA Silt Fence (SF) Inlet Protection (IP) Site clearing and grubbing Vehicle Tracking Control (VTC) Concrete Washout Area (CWA) Soil Stockpiles SP Silt Fence (SF) Inlet Protection (IP) Overlot grading Vehicle Tracking Control (VTC) Concrete Washout Area (CWA) Soil Stockpiles Silt Fence (SF) Utility and infrastructure Inlet Protection (IP) Vehicle Tracking Control (VTC) installation Concrete Washout Area (CWA) Soil Stockpiles SP Silt Fence (SF) Inlet Protection (IP) Excavation/fill of overlot grading Vehicle Tracking Control (VTC) Concrete Washout Area (CWA) Soil Stockpiles SP Re -vegetation in disturbed areas Seed & Mulch / Landscaping (SM/LS) for final stabilization Silt Fence (SF) Remove temporary BMPs that Inlet Protection (IP) Vehicle Tracking Control (VTC) are no longer required Concrete Washout Area (CWA) Soil Stockpiles SP 17 OLSSON ,I; A 55 0C I AT E5 Spirit at the River Hotel 3.0 BEST MANAGEMENT PRACTICES 3.1 1 Purpose Spirit at the River Hotel, SWMP 017-0150 Section 3.0 of this Stormwater Management Plan will identify the Best Management Practices associated with the project. This section will call out phasing of the BMPs that will coincide with the sequencing for major construction activities on the site. A section of technical drawings and installation specifications of each BMP will also be included. Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to ensure all BMPs called out in this plan are adequate for the current conditions on site. It is the responsibility of the SWMP Administrator to make necessary changes to the SWMP concerning BMPs, when BMPs are replaced or new BMPs are needed on site due to changing site conditions in order to keep the site in compliance with the stormwater permit. 3.1.2 Description and Maintenance Structural and non-structural BMPs shall be implemented on site to help prevent erosion and sedimentation. Below is a description of each on site BMPs purpose, limitations, installation, inspection, and maintenance requirements. Temporary and permanent erosion sediment controls shall be used to provide soil stabilization and divert stormwater runoff for both pre- and post -construction conditions. Structural controls. such as fugitive dust mitigation, will be used to limit off -site tracking of sediment during construction. All BMPs used on site must be maintained in effective operating condition and in accordance with good engineering, hydrologic, and pollution control practices. During routine inspections, the site BMPs must be inspected for their effective operating condition. If a BMP or several BMPs are found not to be operating effectively, maintenance to those BMPs must be initiated immediately. Replacement of failed BMPs must occur immediately upon findings of noncompliance and failed performance of any particular BMP on the project site. New BMPs that are installed or replaced will result in a need to properly update the SWMP and the site map to show the changes. Note: CONTRACTOR SHALL TAKE ALL NECESSARY MEASURES DURING UTILITY INSTALLATION TO ENSURE THAT SEDIMENT IS NOT RELEASED FROM THE SITE.

The WQCD's General Permit for Stormwater Discharges from Construction Activities allows for dewatering of groundwater and stormwater to the ground surface to allow for infiltration on the site. No groundwater from construction dewatering will be discharged as surface runoff or to surface waters on the site. It is not anticipated that dewatering activities will be required during this project. However, if dewatering becomes necessary, groundwater and/or stormwater may be pumped from excavations or trenches to the ground surface on the site for infiltration or evaporation. The location of pumping and deposition of the groundwater or stormwater will be marked on the site plan prior to the start of pumping activities. If it becomes necessary to pump groundwater off site or into a waterway or storm sewer, then a groundwater discharge permit must be obtained from the State prior to engaging such activities. The following table lists remaining non-stormwater discharge activities and the associated BMPs (structural and non-structural) used to minimize and eliminate discharge of pollutants.
