This soil has severe limitations for building sites. The site needs to be artificially drained and protected from flooding. Dwellings with basements should not be constructed on this soil.

This soil has severe limitations for building sites. The site needs to be artificially drained to prevent wetness from becoming a problem. Dwellings with basements should not be constructed on this soil. This soil has severe imitations for local roads and streets because of seasonal high water table and high potential frost action. The base material for roads and streets should be replaced or strengthened with suitable material. Note: Soil Descriptions and Characteristics shown were taken from the Soil Survey of Hamilton County, Indiana USDA Soil Conservation Service. Recommendations and methods to overcome soil limitations: _imitations for local roads, streets and dwellings because of seasonal high water table and high potential frost action can be overcome by the use of curb underdrains, sub -base strengthening or lime stabilization. Swales which sever the surface drainage can also help. High water tables can be overcome with respect to basement construction with the use of perimeter foundation drains and sump pumps. Refer to the site construction drawings and details for specific information related to the proposed infrastructure improvements on this site. DANDY BAG Installation and Maintenance Guidelines Installation: The empty Dandy Bag® should be placed over the grate as the grate stands on end. If using optional oil absorbents; place absorbent pillow in pouch, on the bottom (below -grade side) of the unit. Attach absorbent pillow to tether loop. Tuck the enclosure flap inside to completely enclose the grate. Holding the lifting devices (do not rely on lifting devices to support the entire weight of the grate), place the grate into its frame. Maintenance: Remove all accumulated sediment and debris from surface and vicinity of unit after each storm event. Remove sediment that has accumulated within the containment area of the Dandy Bag® as needed. If using optional oil absorbents; remove and replace absorbent pillow when near saturation.

REFER TO MANUFACTURER'S RECOMMENDATIONS FOR CHANNEL PLACEMENT AND STAPLE PATTERNS. ICI Seedbed Preparation Apply lime to raise the pH to the level needed for species being seeded. Apply 23 pounds of 12 -12 -12 analysis fertilizer (or equivalent) per 1000 sq. ft. (approximately 1000 pounds per acre) or fertilize according to test. Application of 150 lbs. of ammonium nitrate on areas low in organic matter and fertility will greatly enhance vegetative growth. Work the fertilizer and lime into the soil to a depth of 2 -3 inches with a harrow, disk or rake operated across the slope as much as possible. Seeding Select a seed mixture based on projected use of the area (Figure 5 -2), while considering best seeding dates. See Figure 5 -3 this sheet. If toler- ances are a problem, such as salt tolerance of seedings adjacent to streets and highways, see Figure 5 -4 this sheet before final selection. Species Level and Sloping, Open Areas 1.

MULTI -UNIT STORMWATER POLLUTION PREVENTION PLAN LEGEND PROVISIONS FOR EROSION AND SEDIMENT CONTROL ON INDIVIDUAL BUILDING LOTS: DROP INLET PROTECTION SOIL SALVAGE AND UTILIZATION Ps PERMANENT SEEDING U CURB INLET PROTECTION 1. The Townhome operator, whether owning the property or acting as the agent of the property owner, shall be responsible for erosion and sediment control requirements associated with activities. 2. Temporary seeded areas established by the developer shall be maintained by the homebuilder and his sub contractors. Silt fences previously installed will be maintained. 3. Installation and maintenance of a stable construction site access drive from the house /site to the street shall be installed, consisting of Number 2 Stone, 6" thick and a minimum of 12' wide. Top dress as needed. This shall be utilized for access to the house and any mud or dirt tracked into the street shall be promptly removed and placed in a stable area. Water shall not be used to flush silt, mud or debris into the storm sewer system. 4. Installation and maintenance of appropriate perimeter erosion and sediment control measures prior to land disturbance. A silt fence is to be installed along the back of curb at the front property line and along the swale or at the edge of the building area. The silt fence shall be maintained until permanent vegetation (grass) is established. 5. Mechanical "High Lifts" shall operate in one of the following ways to prevent sediment tracking. a. High Lift shall not exit building area onto pavement to transport building materials until completion off project. b. Entire building area shall be mulched to a sufficient amount that the High Lift will not track sediment around or from building site onto pavement. c. High Lift shall only exit building area via construction entrance. High Lift tires shall be cleaned prior to exit to keep sediment onsite 6. Sediment discharge and tracking must be minimized throughout the land disturbing activities on the townhome block until permanent stabilization has been achieved. 7. Clean -up of sediment that is either tracked or washed onto roads. Bulk clearing of sediment shall not include flushing the area with water. Cleared sediment must be redistributed or disposed of in a manner that is in compliance with all applicable statutes and rules. 8. Adjacent townhome blocks disturbed by an individual townhome operator must be repaired and stabilized with temporary or permanent surface stabilization. 9. When time is appropriate and as soon as possible, roof down spout extenders of a non perforated drain tile should be extended to the street or other solid outlet until a lawn is established. 10. For individual townhome blocks, final stabilization meeting the criteria of Rule 5 will be achieved when the townhome operator: a. Completes final stabilization; or b. Has installed appropriate erosion and sediment control measures prior to occupation of the townhome by the owner and has informed the owner of the requirement for, and benefits of, final stabilization. 0 cn LiJ 0O II,,, Q Q G \STER No. 0• 10000075 STATE OF Y '/VpIA S S ONAL 'ulrrmul111au�� DATE: 1/30/06 THIS DRAWING AND THE IDEAS, DESIGNS AND CONCEPTS CONTAINED HEREIN ARE THE EXCLUSIVE INTELLECTUAL PROPERTY OF THE SCHNEIDER CORPORATION, AND ARE NOT TO BE USED OR REPRODUCED, IN WHOLE OR IN PART, WITHOUT THE WRITTEN CONSENT OF THE SCHNEIDER CORPORATION.
