(http: / /www. newportbeachca. gov /Modules /S howDocu m e nt.aspx ?documentid =8614) <br />As outlined in Chapter 10, the Upper Newport Bay Upland Restoration Program includes 25 projects along <br />the periphery of the bay in an effort to stabilize slopes, remove invasive plants, remove illegal trails, <br />rehabilitate walking trails, plant coastal sage scrub and cactus scrub, refurbish wetland areas, and create <br />bird - watching lookouts. <br />The proposed Bayview Heights Drainage Improvement Project fits into this overall restoration effort as the <br />project would improve a site that has experienced significant erosion (see attached photo). It appears this <br />erosion began in the early 1950s with the construction of the Bayview Heights — Unit 4 development on <br />unincorporated land. <br />Drainage from a portion of the new tract was directed onto the new streets and then concentrated into a <br />catch basin on Mesa Drive. This flow was then piped under Mesa Drive and released into an open swale <br />flowing onto and through two private properties now owned by Buck Johns (2600 Mesa Drive) and Buddy <br />Cox (2612 Mesa Drive), down a bluff in an erodible and non - engineered channel before draining into <br />Upper Newport Bay. Storm flows have incised a channel between the two private properties that in some <br />areas reaches 15 feet deep. Drainage of concentrated flows over the bluff face in an erodible channel <br />would not be permitted today under current land development codes and regulations. <br />The private property owners approached the City four years ago for advice on how to correct the erosion <br />occurring on their properties. Public Works reviewed the situation with the property owners and explained <br />as the watercourse is on private property, it is the responsibility of the property owners to allow for the <br />storm flows to be safely conveyed across the property including protecting the slope from erosion. <br />Additionally, it is standard practice that once an owner or developer constructs the required drainage <br />improvements and dedicates an easement to the City, the City would be willing to accept those drainage <br />improvements and takeover maintenance of the facility. <br />Understanding the on -going erosion concern and the need to prevent sediment from entering the bay, staff <br />combined efforts with the Newport Bay Conservancy and the County of Orange to try and team with the <br />private property owners and facilitate a long -term and equitable solution for all interested parties. After <br />many years of discussion and looking into solutions, Public Works staff, with the assistance of the Newport <br />Bay Conservancy, developed the following strategy to move the project forward. If the three property <br />owners (Buck Johns, Buddy Cox and County of Orange) agreed to pay a consultant to prepare the <br />construction documents (drawings, specifications, easement documents, environmental documents and <br />permit applications), the City would agree to <br />1. Hire and manage the design consultant (estimated design consultant fee: $180,000). <br />2. Assist the consultant with answering questions from the resource agencies (Coastal Commission, <br />Regional Water Quality Control Board, Department of Fish and Wildlife and US Army Corps of <br />Engineers). <br />3. Apply for a Measure M grant to fund the construction. <br />4. Advertise the project for construction (estimated construction cost: $275,000). <br />5. Manage and inspect the project. <br />6. Manage the Measure M grant. <br />7. Accept the facilities once the project is successfully completed. <br />Because of the complex permitting, multi -party coordination and grant requirements, it is expected that <br />staff will spend considerably more than average time managing the project. The City's contribution to this <br />project is then approximately $305,000 in grant funding as well as an estimated $30,000 to $50,000 in staff <br />resources to oversee, facilitate and manage the project. <br />With an agreement in concept by all parties on the above outlined plan, the City developed a concept plan <br />(see attached) and prepared an application to the Orange County Transportation Authority for a Measure <br />M water quality grant that has now been approved and awarded for $305,000. Of this grant, $30,000 is <br />slated towards the project's design effort and $275,000 for the project construction. Under the provisions <br />of the grant, the design needs to be completed and the City must award the construction contract by June <br />30, 2015. The City has now prepared and circulated a cost sharing agreement to the three property26 -2 <br />
