Connie Kamit Acting Purchasing Agent Cecil County, Maryland Attachment #1
Attachment #1 Recommendations: Planting: The planting project is to expand a riparian forest buffer along the north and west sides of McGill and Back Creeks and will consist of 100 container grown trees planted within 2.5-foot diameter mulched circles. Each tree planted needs to be at least one-inch caliper or bigger as delineated on Figures 2A thru 2G. The planting will also consist of 152 container grown shrubs and 540 container grown herbaceous perennials in the areas delineated on Figures 2A thru 2G. The shrubs must be grown in 3-gallon containers and the herbaceous perennials, in 1-quart containers. All mulch to be used for the planting plan shall be shredded hardwood mulch and must be applied to a depth of at least 3 inches. Mulch should be topped once a year in the spring for the bigger trees only for each of the two years of required maintenance. Additionally, tree bark protectors made with open mesh netting are required to be installed around each tree, and they must be at least 4 feet tall. Each tree bark protector must be tied to one wood stake, to ensure longer term protection. For the bigger trees, this plant material must be inspected prior to purchase, will need metal cages placed within 10-ft diameter circle around each tree, must be 4 feet tall, and have three stakes placed for each tree, to provide wind support. Finally, the bigger trees may be a B & B size. The tree protection will help limit the damage caused by deer and other wildlife, while allowing for air, water, and light to reach the trees. All bamboo stakes that are meant to support the young trees inside the containers must be removed at the time of planting. The 100 trees, 152 shrubs, and 540 herbaceous perennials must be installed by October 15, 2018. The plants were selected based on an analysis of the surrounding native forest. They were also selected due to their suitability to grow in the Coastal Plain Region of Maryland, as well as their abilities to reduce sediment and nutrient pollution and their high value to wildlife. The trees and shrubs should be randomly mixed, arranged in clusters to mimic natural forest stand distributions, and planted in accordance with Figures 2A thru 2G. Plants which demonstrate some resistance to deer browse were also selected. Plant species may be substituted and sizes adjusted, with prior approval. This includes recommendations on plants suited for deer resistance, black walnut toxicity, and fall planting hazards. To meet the objectives for this planting, the following plant lists must be used.

Maintenance:
Survival Inspection: The Contractor shall provide a 2 year warranty on all plant material and shall replace plant material as needed to ensure 75% survival. In September of 2019, after the first full growing season, Cecil County Department of Land Use and Development Services will conduct a joint survival inspection with the contractor to determine a survival rate and the need for reinforcement plantings. The survival inspection is typically performed before the trees lose their leaves in the fall. In September of 2020, the final inspection will take place with both the Cecil County Department of Land Use and Development Services and the contractor present to determine whether the 75% survivability requirement has been met. If it has not been met, reinforcement plantings will be provided by the Contractor at no additional cost to the County, in order to meet the threshold prior to warranty release. The 75% survivability threshold must be maintained each year throughout the duration of the 2 year warranty. Reinforcement plantings will also require new mulch and appropriate tree protection to be installed.
Mulch: Mulch must be topped once a year by May 1st for each of the 2 years of required maintenance for the bigger trees. Mulch circles must be provided initially around the trees and shrubs, and the planting areas for the herbaceous perennials must also be mulched. Only the bigger trees will need the mulch topped each two more times after the initial mulching, to a depth of one-inch.
*See Concept Maps: Figure 1 – Site Location & Figure 2 – Planting Plan.
Special Provisions:
The Contractor agrees to begin planting the plants at a date mutually acceptable to both parties and to complete the planting of 100 trees, 152 shrubs, and 540 herbaceous perennials by October 15, 2018, provided that planting shall not be done when excess water is standing on the tract or when the ground is frozen or extremely dry. Tree planting and associated mulching shall conform to industry standards.
