OF IOWA 2730 Ford Street Ames, Iowa 50010 • EROSION AND SEDIMENT CONTROL PLAN STONE BROOK SUBDIVISION PROJECT DESCRIPTION The purpose of the proposed project is for the construction of a new residen- tial subdivision in the City of Ames, Iowa. The site is approximately 70 acres located adjacent to the Top-O-Hollow Road and Bloomington Road inter- section. The subdivision will consist of town homes, patio homes , single family lots , streets , and open space as indicated on sheet three of the accompanying plan$. EXISTING SITE CONDITIONS The proposed site is an area of rolling plains and lowlands, the majority of which was formerly in agricultural production. A portion of the site is covered with natural growth of grasses , shrubs, and large stands of trees. The site is divided into two distinct drainage areas as designated on sheet three as areas I and II . Both areas eventually drain toward the northeast corner of the site. The slopes vary from nearly 0% to 15% with the steeper slopes being fairly short and perpendicular to the ridges. SOILS Several varying soils will be disturbed during construction. The majority of the upland soil is Clarion loam that is slight to moderately eroded in some areas. These soils are well drained with moderate permeability and high available water capacity. Clarion series are susceptible to erosion. Other small areas of Nicollet loam and Canisteo silty clay loam will also be dis- turbed in the upland region of the site. Nicollet loam is a somewhat poorly drained soil with moderate permeability and the available water capacity is high. Canisteo silty clay loam is poorly drained and found in slightly de- pressed areas. Permeability is moderate and available water capacity and or- ganic material content are high. Storden loam is the predominent soil found on the steeper side slopes. The Storden series consists of somewhat excessively drained and severely eroded soils. Because of rapid runoff, the soil tends to be droughty. The lower flat land area consists of Coland clay loam and Zook silty clay loam. These soils are poorly drained with slow permeability and are subject to flooding. Terril loam is found on the foot slopes and is moderately well drained. This soil has moderate permeability and a high available water capacity. Terril loam is subject to rilling or gullying from runoff from adjacent uplands. CRITICAL EROSION AREAS The critical erosion areas may be identified along the steep slopes tran- sitioning from upland to flat lands. The site was developed to minimize land disturbance in these areas. Where grading is necessary, adequate pre- cautions will be taken to minimize erosion and trap sediment on the site. EROSION AND SEDIMENT CONTROL MEASURES Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will be constructed and maintained as suggested in the Guide- lines for Soil and Water Conservation in Urbanizing Areas. STRUCTURAL PRACTICES 1 . Temporary Sediment Traps A system of temporary sediment traps consisting of silt fence will be installed below major graded areas as indicated on sheets 1 and 2 of the plans. 2. Outlet Protection Riprap is to be placed at the outlet of all storm sewer pipes. 3. Temporary Construction Entrance P Y A temporary construction entrance shall be installed where the access • road intersects Bloomington Road. During wet weather conditions, drivers of construction vehicles will be required 'to clean their wheels before entering the road. 4. Storm Drain Inlet Protection All storm drain inlets shall be protected during construction. VEGETATIVE PRACTICES 1 . Topsoil Stockpile Topsoil shall be stripped from areas to be graded and stockpiled for later use. Stockpile locations are as shown on- the plans. 2. Temporary Seeding Topsoil stockpiles and all areas to be rough-graded during the initial phase of construction shall be seeded with fast-germinating, tempor- ary vegetation immediately following grading. Selection of the appropriate seed mixture will depend upon the time of year it is to be applied. MANAGEMENT STRATEGIES 1 . Construction should be sequenced so that grading operations can begin and end as quickly as possible. 2. Sediment trapping measures shall be installed as a first step in grad- ing and shall be seeded immediately following installation. 3. Temporary seeding or other stabilization shall follow immediately after grading. 4. Areas which are not to be disturbed shall be clearly marked by flags, ribbons, etc. Only a.reas to be built on will be disturbed. 5. The Contractor shall be responsible for the installation and mainten- ance of all erosion and sediment control practices. -3- 6. If any areas exhibit erosion during construction that are not handled ' under this plan, appropriate measures will be taken to alleviate the situation. PERMANENT STABILIZATION All areas disturbed by construction will be stabilized with permanent seeding immediately following finish grading. Seeding will be done in accordance with DIVISION XII , "Specifications for Erosion Control" , City of Ames Standard Specifications. Permanent diversions will also be incorporated with walk ways to provide slope stabilization on the steep side slopes as shown on page 3 of the plans. STORMWATER MANAGEMENT Stone Brooke's comprehensive stormwater management plan is still in the devel- opment stage pending a study of the Hallett drainage basin. A preliminary design is shown on page 3 of the plans showing a large detention basin and permanent lake. MAINTENANCE In general , all erosion and sediment control measures will be checked regularly and after each significant rainfall . The following items will be checked in particular: 1 . The silt fence sediment traps will be checked regularly for sediment cleanout. 2. Storm sewer outlets will be checked regularly for sediment buildup which will prevent drainage. 3. All seeded areas will be checked regularly to see that a good stand is maintained. Areas will be fertilized and reseeded as needed. PROJECT SCHEDULE Construction dates have not been set; however, the following schedule will be -4- used as a guideline. 1 . Clear and grub 2. Earthwork and grading 3. Install utilities 4. Temporary seeding 5. One idle winter season 6. Construct roadways 7.
