3. Where applicable This practice applies to fine graded areas on which permanent, long lived vegetative cover is the most practical or most effective method of stabilizing the soil. Permanent seeding may also be used on rough graded areas.
4. Policies:
a. Criteria found in planning and design manual for the control of erosion, sediment and storm water will be used.
b. This practice will be maintained for a minimum of ten (10) years.

a. Seeds, stolens, sprigs or sod
b. Fertilizer
c. Lime
d. Planting
e. Installation of materials (1 - 3)
XIII. WQ 21 - Stream Crossing
1. Definition A travel-way constructed across a stream to allow livestock, equipment, or vehicles to cross with minimal disturbance to the stream ecosystem.
2. Purpose Prevent or minimize water degradation from sediment, nutrient, and organic loading. To protect the water course from degradation and adverse hydrological impacts. To protect the land from streambank erosion. To provide a means for animals, equipment, or vehicles to cross a water course.
