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 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. CrA Crosby silt loam, Soil Description and Characteristics: The main soil features that adversely affect engineering uses of this soil are a seasonal high water table, high potential frost action, moderate shrink -swell potential and moderate permeability. 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 limitations 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. MoC3 Miami Clay Loam, Soil Description and Characteristics: The main soil features that adversely affect engineering uses of this soil are moderate potential frost action, moderate shrink -swell potential, moderate permeability. In addition, erosion is a hazard during construction. This soil is suitable for building sites, properly designed foundations, footings, and basement walls and using foundation drains help remove excess water and to prevent structural damage from shrinking and swelling and low strength of the soil. This soil has severe limitations for local roads and streets because of low strength. The base material for roads and streets should be replaced or strengthened with suitable material. Recommendations and methods to overcome soil limitations: Limitations 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.

ONE FOOT OVERLAP ONTO THE CURB NOTE: GRADE (NEW OR EXISTING))\ 11= III -III 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.

The individual lot 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 on individual lots. 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 /alley 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 /alley 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 alley or at the edge of the rear drainage easement. The silt fence shall be maintained until permanent vegetation (grass) is established. 5. Sediment discharge and tracking from each lot must be minimized throughout the and disturbing activities on the lot until permanent stabilization has been achieved. 6. 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. 7. Adjacent lots disturbed by an individual lot operator must be repaired and stabilized with temporary or permanent surface stabilization. 8. 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. 9. For individual residential lots, final stabilization meeting the criteria of Rule 5 will be achieved when the individual lot operator: a. Completes final stabilization; or b. Has installed appropriate erosion and sediment control measures for an individual lot prior to occupation of the home by the homeowner and has informed the homeowner of the requirement for, and benefits of, final stabilization. 0 0 pONT,B ,��G1STF No. 0000075 STATE OF 0 •NDIAN /ONAL DATE: 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.
