HomeMy WebLinkAboutWPO202100064 Plan - VSMP 2021-11-10 (15)Irrigation: New seedings should be supplied with adequate moisture. Supply water as needed, especially late in the season, in abnormally hot or dry weather, or on adverse sites. Water application rates should be controlled to prevent excessive runoff. Inadequate amounts of water may be more harmful than no water. Re -seeding: Inspect seeded areas for failure and make necessary repairs and reseedings within the same season, if possible. a. If vegetative cover is inadequate to prevent rill erosion, over -seed and fertilize in accordance with soil test results. b. If a stand has less than 40% cover, re-evaluate choice of plant materials and quantities of lime and fertilizer. The soil must be tested to determine if acidity or nutrient imbalances are responsible. Re-establish the stand following seedbed preparation and seeding recommendations. Maintenance of Mulching All mulches and soil coverings should be inspected periodically (particularly after rainstorms) to check for erosion. Where erosion is observed in mulched areas, additional mulch should be applied. Nets and mats should be inspected after rainstorms for discoloration or failure. If washouts or breakage occur, re -install netting or matting as necessary after repairing damage to the slope or ditch. Inspections should take place up until grasses are firmly established. Where mulch is used in conjunction with ornamental plantings, inspect periodically throughout the year to determine if mulch is maintaining coverage of the soil surface: repair are needed. Maintenance of Dust Control 1. Permanent Vegetation- The application of permanent seeding and saving existing trees and large shrubs can help reduce soil and air movement from construction sites. 2. Stone- Crushed stone or course gravel can be used as a permanent cover which will provide control of soil emissions.
