Can you avoid locating the improvements on the most sensitive portion of the site and is there a suitable area to do so? YES X NO Please specify means taken to avoid: majority of the site is within the RPA and only trying to building on the area connected to an improved public R/W 13. If an alternative location is not feasible please state why this project deserves special consideration: the proposed improvements are on a site with 14 previosly recorded lots and half of the lots and area will be preserved from development Please specify means to minimize the impacts of development for water quality protection: Silt Fence, Tree Protection/Barriers, Limit construction activity to flat areas of site, Single construction/access way, Stockpile construction materials and debris on hard surfaces, and Barriers to define limits of construction activity/land disturbance. 14. Please describe the construction sequencing for this project: Obtain permits, hold pre-construction meetings, install silt fence and tree protection, construct improvements, install buffer restoration and mitigation, BMP's, and immediately seed and mulch denuded areas upon completion of the project. Also see the attached construction sequence as described by the contractor 5
15. Please describe the topography of the site and the condition below that best depicts the area where the improvements are proposed. 6
