CESSWI Part 2 Questions and Answers 100% Accurate 2024 Existing Veg, Desc/Purp temp or perm bmp desi to stab soil and remove sups part from sheet flow runoff. Existing Veg, Objectives 1) Site Plan and Mang 2) Erosi Cont 3) Sedi Cont 4) Post-Cons Mang Existing Veg, applic 1) Areas within site where no const activity is occur 2) Areas where local, state and fed govt require preservation 3) Areas where existing veg can be utilized for eros, sedi, and storm water quality. Existing veg: inspection 1) Accord to regu timetables 2) erosi and damage veg 3) sufficient moisture to ensure growth 4) veg is well stab 5) adequate cover 6) debris and litter 7) invasive exotics Existing veg: maint 1) only disturb area for construct 2)irrigate dry seasons 3) remove see, and replant if need be 4) replant or rework buffer strips 5) mow and cut perennial weeds 6) remove all trash and debri 7) treat invasive and noxious species Sched/Sequ, purp/descrip Temp, procedural control that involves creating a written plan to address neck bmps and sequencing of construct activities to mitigate the erosive effects of wind,water and construct activities. Sched/Sequ: object 1) site planning & management 2) erosion control 3) sediment control Sched/Sequ: applications 1) develop timetables for certain activities, paretic during rainy season Sched/Sequ: inspect 1) inclusion of sched/seq as a bmp in the plan 2) ached site activities mirroring ached activites. Sched/Sequ: maintanence 1) modify ached of active when changes are warranted 2) modify ached of active prior to rainy season to reflect updated bmp info Hydroseed: Des& purp Temp or perm bmp designed to reduce erosion and runoff by applying mix of seed, fert and stabilizing emulsion. Hydroseed: object 1) erosion control 2) good housekeeping/ materials management 3) post construct management Hydroseed: targeted pollut 1) sediment 2) nutrients 3) metals 4) ph Hydroseed: imp consid 1) need adequate moisture 2) additional mulch may be added 3) pretreatment where cover is not met 4) apply from multi angles to avoid shadowing Hydroseed: limitations 1) seed mix approp for seasonal conditions 2) time of application per seasonal conditions 3) difficult on steep slopes 4) no pedestrian or vehicle traffic 5) avoid high winds Hydroseed: inspect: 1) adequate coverage of diet areas 2) signs of pedest or vehicle traffic 3) signs of animal activity 4) check seed mix for correct type and application rate Hydroseed: Maint 1) reapply in areas needing more cover 2) insure proper moisture 3) maintain unbroken coverage through out project 4) require repair due to traffic or animals Hydroseed: potentailly assoc bmps 1) hydromulch 2) seeding 3) mulching 4) temp stabi 5) tackifiers RCP: descript and purp temp or perm erosion control blankets that act as soils stabilization devices to protect diet areas from erosions. RCP: object 1) erosion control 2) runoff control 3) post construct RCP: target pollutants 1) sediment RCP: applications 1) on slopes w/ potential for erosion 2) flow velocity reduction 3) temp channel stab 4) soil/rip-rap seperator 5) soil stabi 6) aid in germination 7) increase soil infiltration 8) stockpile protect RCP: limitations 1) ped and vehic hazard 2) not for use in rocky, established veg will be mowed and high fire 3) blankets dislocated easily 4) uv degradable 5) small animals can be trapped RCP: imp consid 1) material depends on site 2) soils should be prop prepared 3) instal per manufact recommedations. RCP: inspect 1) sufficient staples 2) provide anchoring and overlap 3) insure direct contact with soil surface 4) no rips or tears 5) verify rcp meets plan/swpp specifications. RCP: Maint 1) direct contact with recp and soil 2) repair/reinstall where needed 3) repair rills or gullies 4) replace staples where needed 5) material may get entangled in mowers RCP: potential assoc bmps 1) seeding 2) swales 3) filter strips 4) diversions Bmps used for erosion control 1) hydromulch 2) Hydroseed 3) Mulching 4) RECP 5) seeding 6) Sod 7) Soil binders 8) surface roughening 9) tackifiers What are best management practices? 1) site planning and management 2) erosion controls 3) sediment controls 4) runoff controls 5) good housekeeping/ materials management 6) post construct management Bmps designed for sediment control 1) baffles 2)Cut-back curbs 3) fiber rolls 4) sediment bags 5) temp stream crossing 6) sediment basins 7) sediment traps 8) silt fence 9) skimmers 10) stabilized entrances and exits 11) turbidity curtains Sediment basin: descri & purp a structural bmp that allows stormwater to be collected, and allows sediment present to fall out of suspension before teh water is allowed to undergo controlled release Sediment basin: Object 1) sediment control 2) runoff control 3) post construction management Sediment basin: Target pollutants 1)sediment 2) trash 3) hydrocarbons/petroleum products 4) turbidity 5) metals Sediment basin: applications 1) where sediment laden run-off has the potential to enter storm drain systems or waterways Sediment basin: Limitations 1) basins should be placed where failure will not cause injury to persons, property or utilities 2) large area is required 3) standing water, which is ideal place for vector prduction(mosquitoes, etc) Sediment basin: Impl consid 1) good idea to block public access to basin with fencing 2) construction should comply with state provincial, and local safety laws, ordinances, rules and regulations Sediment basin: Inspect 1) erosion around inflow and outflow points 2) sediment buildup and trash 3) proper drainage area 4) slope and embankment stabilization 5) properly sized outlet devices with dewatering and stabilized outlet 6) access for maintenance
