Tree Inventory Work Plan To ensure that the tree inventory meets the City’s goals and deadlines,DRG uses the following work plan. Step 1.Communication From project beginning to end,DRG stakeep open lines of communication with the City of Roseville via telephone,e-mail,and,as needed,in-person meetings.DRG answers any questions Roseville has as well as keeps the City apprised of the project's progress. Step 2.Contract Phase Once awarded the project,DRG executes a contract and supplies insurance per project specications. Step 3.Data Mining and Hardware Programming The next step in the inventory process is to obtain the GIS data and imagery needed to set up the eld computers used for data collection.DRG's urban foresters typically work with the City’s GIS or planning department to complete this step.If necessary,we can get imagery from other public sources.DRG uses the data elds dened in this proposal and the imagery,maps,and data les obtained from the City and various sources to program the data collection software and eld computers.At this time,we may contact you by phone to conrm the data attributes. Step 4.Kick-Off Meeting DRG stawill contact the City after contract execution to schedule a kick-omeeting.During the kick-o meeting,Roseville’s staand the DRG project team discuss inventory safety and communication procedures and conrm project expectations and milestones.If possible,DRG’s urban foresters assess a few trees with City stato ensure consistent assessment results. Step 5.Data Collection DRG typically begins data collection after the kick-o meeting.Our experienced,qualied urban foresters locate trees,planting sites,and stumps along maintained street ROWs and in public parks and properties,evaluate those trees and record the data specied by the City.The collected data,once nalized,are Roseville’s tree inventory database. Accessing Inventory Data DRG supplies access to the tree inventory data during data collection.To access tree records,utilize TreeKeeper®to view and eld check data and even to route and plan for tree work. Location Accuracy DRG uses eld computers and equipment that meet or exceed this project’s location accuracy requirements. Having worked on thousands of tree inventory projects,DRG has found that using a combination of GIS and a customized data collection program provides the most exact data and the most ecient means for inventorying trees.DRG uses our in-house designed GIS software tool in conjunction with ruggedized computers with a GPS receiver to collect inventory data.Under favorable conditions,the equipment allows for sub-meter location accuracy of point data.
