This flEVISED amendment modifies AECOM's proposal dated November 30, 2015, and is based on recent discussions with staff irom ihe City ot Oshkosh (City), including Mc Steve Gohde of Engineering and Ms. Elizabeth Williams ot Planning. This amendment includes our understanding of the proposed project, our proposed scope of services, and estimated fees. UndersWndina We understand the Ctty ot Oshkosh is planning to redevelop the vacant parcel loca[ed east of Grove Street, benveen Cleveland Avenue and East Parkway Avenue. The entire parcel is approximately 1.2 acres in size, relatively level, and grass covered. The City in[ends to divide this parcel into two lots by Certified Survey Map (CSM). Proposed Lot 1 will be comprised of the southern portion ot the parcel, and is to be 0.33 acres (14,000 square teet). Proposed Lot 2 will he comprised of the middle and north portion of the parcel, and is to be approximately 0.91 acres. 8oth Lots are zoned R-5 PD. Sidewalk easements exist along Cleveland Avenue antl East Parkway Avenue; Ihese are to be dedicated as part of the City's righ�-of-way. Task 1 is to prepare a Certified Survey Map of ihe property which divides the lots as noted above and incorporates ihe easements. The proposed development plan for Lot 1 is the constmction of a Iwo-unit handicap accessible residen[ial stmcture with approxima�ely 2,600 square fee[ of living area (1,200 square feet for Unit 1 and 1,400 square feet for Unit 2). An anached garage will include 600 square feet for Unit 1 and 700 square feet for Unit 2. Green space will constitute 54 % of the site, while impervious surfaces (buildings, patios, and driveways) will cover 46 %. Tasks 2 and 3 are [o prepare ihe civil sRe design and storm water management plan for the Lot 1 development only. The storm water management plan is to include a rain garden to comply with the City's requirements for storm water treatment. AECOM has previously completed a Phase I ESA and Subsurface Geotechnical Evaluation for the site. W e propose [o amend Ihe Subsurface Geotechnical Evaluation agreement to add ihe survey, civil site design, and storm water management plan services to the geotechnical project budget. eaaaaeoa aeviseanmanamenu.aoc, ❑�xK.nci Scooe of Services Task i: Certified Survey Map and Topographic Survey Certified Survev Mao AECOM will prepare a iwo-lot Certified Survey Map (CSM) adhering to City of Oshkosh and S[ate of Wisconsin standards. The CSM will incorpora�e other requiremenis already established, induding: 1. The final CSM will include a note �hat both Lot 1 and Lot 2 are required to meet fhe City's "curren[ storm water management requirements at time of developmenC' Presently, the 2016 standard is 40 % reduction in total suspended solids (TSS) for a re-development area. This removal standard will be utilized in Task 3 to design Lot 1. However, because developmeN ot Lot 2 may occw well into the tuture, City s[aH requested Ihat the no�e reflect compliance with standards �hat may be in force at ihat time. 2 Sidewalk easements located along Cleveland Avenue and East Parkway Avenue will be dedicated as right-of-way. The easement along Cleveland Avenue extends beyond ihe proposed Lot 2 boundary. Theretore, [his will require preparation of an Easement Release document. AECOM will prepare this documen� with the understanding ihat the City will handle ihe release process. The easement along East Parkway Avenue is only on ihe proposed Lot 1 area; therefore, an Easement Release document is not required tor this easement The City will also handle Ihe release process for the East Parkway Avenue easement. 3. The tinal CSM will designate ihe boundaries of Lots 1 and Lot 2 per the planning commission recommendation. 4. AECOM will provide a Survey Plat for the North Grove S[reet Two Unit Residential development. T0000raohic Survev AECOM will prepare a bpographic survey of the project site (Lots 1 and 2) and will extend the survey to adjoining sireet centedines and 20 feet beyond other property lines. Sufficiem data will be gathered to prepare a sudace model and onedoot contours of the surveyed areas. In addition to surveying the physical features unique to ihe site, existing concrete joints, if any, will be located along with visible overhead, surface, and sub-surface utilities based on observations and/or markings provided by contacting Diggers Hotline. Other than features visible and encountered during normal surveying operetions, subsudace and/or obswred at-grede utilities or improvements will not be loca�ed other than those marked by utility tlags or paint marks. The CAD deliverable will be prepared to �he standard required for an in-house AECOM design. NOTE: All horizon[al si[e contml and project deliverables will be surveyed in �he Wisconsin Coordinate Reference Systems (W ISCRS) W innebago County Datum (NA2011). The vertical datum will be NAVD88. Deliverables: AECOM will furnish one (1) drak CSM and Easemem Release document for City staH review. Upon receiving City staff review comments, we will (urnish appropriate signed originals and an electronic file.

These civil site plans will be iransmitted by ihe City to Habitat for Humanity, to be used as part oi their overall bidding and constmction plans for the project The civil site plans will be based upon the architectural drawings prepared by Chet Wesenberg Architect LLC and the following conditions recommended by Ihe November 17, 2015 Plan Commission Site RepoR: 1. Driveway widih will be reduced to a minimum of 18 feet at the property line. 2. Base standard modification to allow a minimum iront yard setback ot 15.5 feet on Grove Street and Eas[ Parkway Avenue. 3. Base standard modification [o allow a minimum yard setback of 7 feet. 4.

The plan will include a pmjec� description narrative, a hydrologic boundary map, and W inSLAMM modeling for storm water quality improvement. This SW MP will include ihe civil plan sat and reference Rain Garden plan and details. Since ihis is a re-development site, runoff rate conirol is not required and will ihus no[ be included in Ihe SW MP. We understand this residential development falls under City building codes. Therefore, a W DNR Notice of Intent (NOI) for a Conshuction Site S[orm Wa[er Discharge permit is not needed.
