Project Description and Scope of Work Currently, stormwater that enters the catch basins along Berkeley Road at the top of the North Woods at Lake Avondale is redirected by an old earth dam to an upland ravine that parallels a natural stream. This upland ravine has no direct connection to the natural stream within the woods but has at one location found a low spot to fall off the upland shoulder to rejoin the natural streambed. This foot drop has A-1

2 eroded the slope to form a dangerous sheer cliff and has since been fenced off. A cut-off wall, design TBD, will be needed to prevent its propagation upstream. In addition, there is a pipe entering the catchment from above presumably from Clarendon Avenue. The City is asking for proposals for design and civil engineering services to provide an engineered solution to this stormwater problem. The solution should provide a corrective structure (may include green infrastructure options) be placed at the top of the park where the stormwater enters and where there is the easiest access but will look to the selected engineer for the best solution. If possible, the City would prefer to remove the earthen dam at the location where the stormwater enters the park to return the stormwater to the natural stream ravine. The design consultant will provide the City of Avondale Estates (the CLIENT) with drawings and permitting necessary for the construction of a stormwater management improvements at the North Woods section of Lake Avondale. The project will include a hydrology report and all associated design documentation intended to accomplish the following project goals: Mitigate the erosive potential of the incoming stormwater, thereby preventing erosion in the North Woods. Reduce sediment loading into the northwest cove of Lake Avondale. Incorporate as much as possible an infiltration or filtration type of Best Management Practice (BMP), with all the associated pretreatment protection and overflow protection, in order to enhance the water quality in Lake Avondale. Provide appropriate hardscape and landscape improvements to make the resulting facility attractive and accessible for maintenance purposes. The design shall treat upstream runoff to reduce total suspended solids in accordance with the Georgia Storm Water Management Manual. The consultant shall evaluate the cost of implementing said water quality BMPs and discuss their findings with the City before incorporating a specific water quality design in the construction documents. If any of these guidelines cannot be followed due to site constraints, these issues will be identified and discussed at the completion of preliminary design. Efforts shall be made to design a project that can be constructed outside of Waters of the US. However, if permitting is necessary, encroachments into Waters of the US shall be limited to that which can be constructed under a Nationwide Permit. Budget: Based on City budget documents, the total budget is approximately $250,000 which includes design, engineering, construction and contingency costs. Projected Timeline: Late 2018/Early A-2

3 Location Map: SCOPE OF SERVICES Task 1 - Preliminary Design Survey the area and create a base map from field survey data. The consultant is responsible for all surveying activities. The consultant project manager and Civil engineer will meet with the CLIENT and his representatives for a project kick-off meeting to discuss the proposed project, the scope of design, and possible design approaches. Site visit immediately following the kick-off meeting by consultant Project manager and Civil engineer to assess existing conditions. Prepare preliminary hydrology report to assess stormwater flows and drainage patterns to the proposed project. Provide any subsurface investigation necessary to support design decisions. This could include an infiltrometer test, the ground water level (both A-3

4 seasonal and average), and other similar tests. Prepare a preliminary grading plan indicating likely limits of disturbance. Prepare a preliminary opinion of probable construction cost based on the preliminary grading plan. Prepare a maintenance plan for each design option, along with projected annual maintenance costs. Present to the CLIENT at least one design option for the project area that will meet all the project goals. Meet with the CLIENT to review the preliminary design options and receive approval to commence with final construction documents. Conduct one public meeting to present findings and discuss conceptual design. This phase should allow for (2) Public Meetings with the City and the City s representatives to review design issues. Additional meetings may be needed to coordinate with the CLIENT prior to public meetings. Task 2 - Construction Documents The following construction documents will be prepared: o Cover Sheet o Civil Notes, Legend, and Abbreviations o Existing Conditions Plan o Site Plan o Grading and drainage plan including profiles and calculations (if required) o Single-phase Erosion, Sediment, and Pollution Control Plans and Details. Area of disturbance is assumed to be less than one acre and 200 feet or more from state waters. If not, a 3-phase ES&PC plan is needed. o Landscape plans and details, utilizing native vegetation o Construction details, including any specifications for soil media and other related materials. o Finalized hydrology report o A detailed maintenance plan specific to the design, including annual and quarterly milestones. The selected consultant will submit preliminary documents at the 90% phase to the CLIENT for review and comment. The consultant will then meet with the CLIENT to discuss the plans and the CLIENT comments. The consultant will prepare an opinion of probable construction cost for each submittal. This document will be created utilizing RSMeans construction cost data. Technical specifications.
