Description And Narrative: Carmel Clay Parks and Recreation is proposing to partially re-develop River Heritage Park, which sits on a portion of a 40-acre park located in the City of Carmel, IN. The project consists of demolition of several concrete walks and an existing playground. The proposed elements include a permeable playground surface, permeable trail surface, raised boardwalk sections, several concrete walks, a shelter roof replacement, four fabric shade shelters, and site furnishings. Two parking spaces will be paved to improve ADA accessibility. Miscellaneous seeding and tree mitigation is also proposed. The purpose of this report is to determine if there were any new water quality or detention measures required for these improvements. b. Drainage Problems: The site is entirely within the regulatory floodway of the White River, with the majority of the improvements being well below the BFE established for this site. c. Procedure of Analysis: The proposed flow rates were calculated using the NRCS Type-II 24-hour method as required for 2,10 and 100-year storm events. The curve numbers were calculated as a composite curve number using curve numbers from the NRCS and the INDOT Hydrology manual where needed. d. Any Assumptions or Hydrologic Conditions: It is assumed that the proposed pervious asphalt trails will have the ability to pass runoff so directly to the soil that the curve number for the soil will be used in the proposed condition. It is also assumed that any depressional storage is negligible as the site is in floodway and any storage for major storm events will be irrelevant. e. Proposed Design Description: The proposed park expansion will install new trails at grade and utilizing pervious materials to make certain there are minimal effects on the existing drainage pattern. These practices have been done to ensure that the existing drainage patterns are maintained after the trails have been constructed. Additionally, the playground area will be redone, and some paths will be replaced for maintenance. We previously submitted and recorded an O&M manual for the pervious asphalt and the native vegetation, and those two BMPs will be used during the construction. f. Results of the Analysis: In the existing and proposed conditions, the runoff rates are very similar. The same time-of concentration is applicable for both scenarios, and the curve number varies only slightly for the same drainage area, which is 28.76 acres of an over 40-acre park. The resulting runoff is increased slightly by this development: 2-year 10-year 100-year Existing 2.89 13.74 53.57 Proposed 3.10 14.29 54.55 Increased Flow Rate 0.21 0.55 0.98 Percent Increase 7.27% 4.00% 1.83% g. Soil Properties: Refer to the appendix of this report for soil map with hydrologic soil group information. The site is 94% type B, so type B was used to simplify calculations. h. Narrative Of Downstream: The receiving water for this site is direct runoff to the White River. As noted below, the river’s floodway encompasses this entire site. i. Any Federal, State, Local Permits: Local MS4 Approval, IDEM, IDNR, Army Corps of Engineers j. Errors Insurance: Included in this report. k. Revision Date: Revision dates are shown on the title page of this report. l. FEMA Flood Statement: The site does lie in a Special Flood Hazard Area as Established by the Federal Emergency Management Agency - National Flood Insurance Program, when plotted by scale on Flood Insurance Rate Map #18057C0233G, Dated November 19, 2014. The site is within the regulatory floodplain. Conclusion: The site improvements do result in slightly higher runoff rates, less than a 2% increase in a 100-year condition. Onsite detention is not feasible due to the site improvements in most cases being 4-to-10-feet below the BFE for the site of 745 feet. Any onsite detention would also be well below the BFE and not constitute a viable detention design. Because of this, no truly new hard surfaces are proposed. The proposed trails are all pervious or wooden boardwalks, and as such the increased curve number is due to the soil below the trail having a higher curve number than the overall wooded area. The replacement of other surfaces, such as existing walks and ADA parking spaces, are maintenance items and are just replacing existing hard surfaces. Overall, the improvements proposed are of minimal consequence to overall release rate and great care has been taken to limit the impacts of the proposed park expansion on the existing wooded areas.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

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 Custom Soil Resource Report 8 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 development of resource plans. 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 Custom Soil Resource Report 9 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.

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 Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 25 Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

The surface system is comprised of a single layer consisting of recycled tire crumb with polyurethane binder throughout the entire depth of surfacing. Maintenance Details: Softline FlexiStep Pathway system is a low maintenance surface. Keeping the surface free from foreign objects such as stones, dirt, stones, leaves, excrement/urine, chewing gum, liquids such as gasoline and oils. Exposure to foreign matter can cause damage effecting the longevity of the surface life. It is recommended that regular, periodic removal of loose debris is performed by using a sweeper (brush), blower or vacuum to prevent forcing particles into the porous surface. Maintenance Tips for Common Pathway Cleaning: Gasoline: Wash area with a mild detergent and water. Soak up the deposits with disposable rags. Apply two rinse applications with water and allow to dry. Moss/Algae/Mildew/Mold: Saturate area with hydrogen peroxide and allow to soak for 5 minutes. Follow with saturating the area with vinegar and allow to soak for 5 minutes. Soak up area with disposable rags. Apply two rinse applications with water and allow to dry. Chewing Gum: Apply dry ice to freeze the gum and chip it from the surface to remove. Soda/Juice: Spray surface with Formula407 and work into the surface with a disposable rag. Soak up the residue and apply a second application of a mild liquid detergent. Apply two rinse applications and allow to dry. Grass Stains: Apply vinegar and water spray (50:50 dilution) to area and work into the surface with a disposable rag. Soak up the residue and apply second application (if required). Apply two rinse applications and allow to dry. Excrement/Vomit/Urine: Wear necessary Personal Protective Equipment prior to starting the cleaning process. Remove any loose excrement. Scrub area with Borax, TSP or STPP solution. Soak up residue with disposable rags. Spray surface area with hydrogen peroxide and let stand for at least 3 minutes, apply a second application of vinegar and let stand for 2 minutes. Soak up the residue with clean disposable rags. Apply 2 rinse applications and allow to dry. FlexiStep Pathway Maintenance Detail 2 877 362 3133 | www.softlinesolutions.net | sales@softlinesolutions.net Snow/Ice/Sleet: Use of sodium and calcium chloride salts for ice control is acceptable. The surface may be cleared by a pedestrian machine with power brush or rubber lined snow blade (set at ¼-½” above the surface). Attempting to ‘scrape’ the surface may cause damage (skid steer or heavy equipment use on Softline FlexiStep surfaces is too heavy and the rubber tire traction against the surface may cause damage). Salt Stains: Use trisodium phosphate liquid per directions. Allow surface to dry and brush off the buildup with a soft nylon brush. Complete every 3 months or as needed to prevent large buildup. Recommended Maintenance Schedule: Bi-Weekly: Perform removal of loose debris using a sweeper (brush), blower or vacuum. It is recommended to increase this maintenance per the City’s guidelines for pathway visitors. In the case of an event bringing increased traffic, increase maintenance accordingly. Quarterly (Winter): Complete salt stain removal process per recommendations, if required. Annual Inspections: Arrange annual inspections with Softline Solutions. Bi-Annual Application (OPTIONAL): Arrange varnish seal application with Softline Solutions. Surface Repairs: In the event of a surface requiring a repair, contact Softline Solutions customer service to obtain a repair kit or repair service by our certified installers. sales@softlinesolutions.net 877 362 3133
