When revegetation is required. Where natural vegetation has been removed through grading in areas not affected by the landscaping requirements and that are not to be occupied by structures, such areas are to be replanted as set forth in this Section to prevent erosion after construction activities are completed.
Preparation for re-vegetation. Topsoil removed from the surface in preparation for grading and construction is to be stored on or near the sites and protected from erosion while grading operations are underway.
1. Such storage may not be located where it would cause suffocation of root systems of trees intended to be preserved; and
2. After completion of such grading, the topsoil is to be restored to exposed cut and fill embankments or building pads and amended with compost to provide a suitable base for seeding and planting.
Methods of revegetation.
1. Acceptable methods of re-vegetation include replanting with native trees, shrubs, and groundcover and hydro-mulching or the planting of rye grass, barley, or other seed with equivalent germination rates;
a. The use of native trees, shrubs and groundcovers plant materials is encourages to reduce irrigation and maintenance demands;
b. The use of lawn and turf should be minimal. Where lawn or turf grass is to be established, lawn grass seed or other appropriate landscape cover is to be sown at not less than 4 pounds to each 1,000 sq. ft. of land area;
c. Other revegetation methods offering equivalent protection may be approved by the approval authority;
d. Plant materials are to be watered at intervals sufficient to ensure survival and growth; and
e. Employ other erosion control techniques as required in Chapter 14.24 VMC Erosion Control. (Ord. M-4179 § 93, 2016; Ord. M-3643, 2004)
