Section 7— Executive Summary This Teniap, System Improvement Plan (Plan) for the Bayehore area has been Prepnfed by Q. Grady Minor & Associates, P . (Gradyclinor)_ The purpose of this Plan was to oval note the existing dram age within the Study area, recommend i mprovementsto the system to alleviate flooding in the area, develop a tertiary aormwater system improvement blur and provide budget cost estimates. The Sandy area is limited to the Bayehore Beautification stupider] Services faxing Unit (MS'FU) area that is not part of a permitted master water management onstem or mobile home complex or apartment complexes. The Ba)avoc MSTU is located in Sections 11, 13, 14 and 13. 'township 50S. Range ISE and is bounded by Naples Bay b the west, US 41 on the North and about on,-h if mile to the east of ^ Bayehore Drive In the east. This area isapproxicni 1,133 acresofthe total 1.391 does n theMSTU area. PACE 4 Packet Page 979- 10/25/2011 Item 13.A.3. Asa part of previously authorised work an arial survey was completed to obtain physical features such as roads, buildings, -enteral elevations and contours. In conjunct on with this aerial survey, field reconnaissance has been completed in the Study area This Geld reconnaissance allowed par review of the general condition or the existing drainage patterns and as stem, An initial Neighborhood Meeting was held with residents of the area to receive input from them concerning Gooding in the Study area. These actions have allowed this Plan to be developed. Portions of the Sudy area are without an enecllvc drainage system. In several locations, Sound; have been tilled either intentionally or by long tens sedimentation. Driveway drivers are a mix of materials and six. Mary culverts have deteriorated and reached the end or their useful life. As a result, these portions of the Study area experiences Ioezllzed Goodin - during smart storm events and overall area funding during larger storm events. Dependent on rainfall and duration, the severity of localized Flooding dan be extreme and long in duration. Other portions of the Study area are hydraulically connected to signiteam permit s >stems (e.g., tidal canals. Lake Avalon pinball ditch to Haldeman Creak and the North -South outfall ditch south ol- Thomaason Drive). The areas connected to the canals tend to be less susceptible to minlell- induced loading. 4 Packet Page -980. 10/25/2011 Item 13.A:3. Weeca Avenue Street Reading In order to address the flooding in the Study area, this Plan has identified a series of recommended improvements- These recommendations am generally not listed In priority, hmvever, to minlmive disruption Insides a priority list has been developed also These projects may combine certain bevel One system improvements with Level Two and Level Three improvements. The first set of recommendation addresses more to the Level One system which consists of stomwater faciries xhrch convey slomxater to a motor outfall. Improvements are recommended at the follomine areas'. . North -South Otuball Ditch south of 9homasson Drive . NyD-SQwh Ditch north of Lake Avalon to Haldeman Creek . Thomason Drive doctrine from North South ditch crossing Bay shore Drive to approximately 100 feet east of entrance to Botanical Garden The estimated cost for these improvements is approximately $1,700,000 to $2.000,000. PACT 6 Packet Page -981- 10/25/2011 Item 13.A.3. AddifomM the Windsor Outfzll Swale (internal to Whistler PuD) for mpo e �..� properties should be completed. This project would be the responsibility of the W indstar commuldor as it is a condition aflhelr water management parmit The next level of priorities adaestes the Level Two system consisting of those emrmwater facilities which convey stormwater from Level Three facilities to me Level One system. Considering the limited number of Level TWO systems, they have been included mine LevelThree facility improvements mprm ¢roams are recommended at the fol lowing areas: Area l (streets within the Weeks and Beeca Avenues area) Area 2(streets within the Buys law and Lakeview Avenues area) Area 3 (stree s v:ithin the Coco and Areas Avenues area) Area 4 arro e s within the Van Buren Avenue (West) and Linda Drive area) Area 5 (streets within the Van Buren Avenue (fast), Lunar Street and.leepers Dive area) Area 6 (streets within the Carnage Grove, Republic Avenue, Woodside Avenue area) Area ] (streets within IM1e Pine Street and Bay Street areal • Area 8 (streets within the Peters Avenue area) The estimated cost for these improvements is approximately 54000,000. Given that some of these Areas are not hydraulically connected to tidal canals (Areas I, 4, 5, 6 and 8), it is recommended that prindty be even to these areas for system improvements In addition, the areas that have not historically been subject to repeated flooding events Packet Page -982- 10/25/2011 Item 13.A.3. should be gives a laver priority (Areas fi and 8). Thus, it is recommended that Areas I, 4 and 5 be given greater priority. Many of the proposed tertiary improvements can be completed as part of an on- going maintenance program not requiring any special Pcol iWng with exception of a Collie County Night -Mi Pemnit. These improvements would include swat, regrading and re- establishment and replacement of driveway culverts up to and including 15' diameter (or equivalent). These would include projects that are Actuary or secondary in nature, Additionally, if street landscaping or sidewalk improvements are made, drainage improvements can sound usually are by necessity pan of those improvements. Other improvements dependent on their scope may require No- Noticed and Noticed General Permits from SPWMD. These would ineludethose generally associated with the tertian- system. n The bevel One system projects will genemlk require a Modification to the existing Environmental Nesouroe Permit issued 6r public projects in the area (Sudden Pad or Bay share Drivel. Potentially there are several sources of humming that could be utilized for these projects, It may be possible for minor wale regrading to be completed b. Collier County Transportation as pan of the on-going maintenance program. Hoverer, County policy generally does not fund Proteins that have limited benefit. 'These could apply to the identified projects in this Plan. Possible other sources of funds include grants directly foam the SPWMD for stommater improvements- S) WMD generally requires an element of water quality PACES Packet Page -983- 10/25/2011 Item 13.A.3. improvements to be incIroad, There are also grants available from me State and Federal agencies for flood related projects. Collier County grant funding is often tied to the local agency providing marching funds. Matching funds can came from limited Community Redevelopment Agency fonds, the Municipal Services Taxing Unit MST( J) or through other special assessment means. All sources of possible funding should be pursued. Addivinni Community Development Block Grant funding may become available from time to time to allow portions of the proiects to be completed. Once e ant funding is secured or assured, construction plan preparation should occur for the portion of the system that is funded. Prior to completion of the plans, permit application shall be made in SF W MD for a construction permit Free these stmmwaler improvements are completed it is equally imponent that they be maintained. This would include regular visual inspection ofstormwater facilities, ^ culverts and ditches for elimination and regular cleaning and regrading at drainage sweles and structures. The completion of these recommendations will go far in alleviating flooding within the Study' area. During unusual or long duration rotor events there may still he some funding, but these improvements will reduce rain induced flooding levels and their duration.
