South: A-R Agricultural-Residential Type B Buffer 15 Feet Zoning District

East: R-1 MH Single-FamilyIMobile Type B Buffer 15 Feet Home Zoning District

West: R-1 MH Single-FamilyIMobile Type B Buffer 15 Feet Home Zoning District

* Buffers are based upon the use of the site as a commercial (nonresidential) type.

4. The preliminarylconstruction site plan has been reviewed by the Zoning and Site Development Department, and it has been determined that the proposed use is consistent with the above-referenced zoning district's permitted uses.

5. The preliminary/construction site plan for the above-subject project was prepared for Pasco County Facilities Management Department by Northside Engineering Services, Inc., and consists of 16 sheets dated February 11, 201 1 ; the sheets were last revised on October 2, 201 1. The plans were originally received by the Zoning and Site Development Department on April 26, 201 1, and the latest revisions were received on October 4, 201 1.

6. Access to the property is from Grey Street, a County-maintained road, which has 50 feet of right-of-way with 20 feet of pavement; and from Barker Drive, a County-maintained road, which has 40 feet of right-of-way with 20 feet of pavement.

7. A Traffic Impact Study application was submitted and found to be exempt from the requirement to provide a traffic study and a Substandard Roadway Analysis.

8. The proposed request is consistent with the Pasco County applicable provisions of the Comprehensive Plan as conditioned.

(2) Provide a soil erosion and sediment controls plan showing all of the necessary placement locations, notes, and details including, but not inclusive of, silt screen, construction/tracking pad Florida Department of Transportation (FDOT) Index 106's or the Florida Department of Environmental Protection National Pollutant Discharge Elimination System Best Management Practices), dewatering, inlets and swale protection, revegetation as necessary.

(3) Please add or modify the following notes:

(a) On the east side of the property runs a six-foot chain link fence. The fence must be maintained as not to block drainage coming from the east. Add a note which requires that as part of the maintenance duties.

(b) All work within the right-of-way will require a Right-of-way Use Permit.

(c) Add a note to the plans that the sight triangles are to be unobstructed and are to remain unobstructed.

(4) The plans shall certify that the roadway system is in substantial conformance with the Manual of Uniform Minimum Standards for Design, Construction, and Maintenance of Streets and Highways, State of Florida, in effect at the time the plans were prepared.

(5) Address the placement of fill including the compaction and lifts on the plans.

(6) Add the rough pond dimensions to the plans.

(7) Within the site plan, locate the various borings and DRI tests (to scalelto a scale).

(8) Provide a cross section through Grey Street (sheet C4.1).

(9) See sheets '(23.1 and C3.3. In the south pond is the word "spillway" which appears to be erroneous or mislocated; revise as necessary.

(1 0) See sheets C2.1, C4.1, and C4.2 section C-C. A new swale appears to be shown to be constructed in the Olympia Street right-of-way. The section does not appear to reflect it. On the plans, revise as necessary.

(11) Provide a Geotechnical Report signed and sealed by a professional geologist and/or a geotechnical professional engineer. See Section 704(.4) for the scope of work.

(12) Provide a soil boring below the proposed structure.

On sheets C4.1 and C6.1. The plan view indicates a 5' x 8' x 6 pad on both sides of the weir. However, on the weir detail, the weir opening is 10+ feet wide. The pad cannot prevent erosion if it is only one-half of the weir width; revise as necessary.

On sheet Ll.1, south property line eastern side, the proposed con- struction cannot cause, aggravate, nor have an adverse effect on the neighboring properties. The proposed swale passes through the proposed landscaping buffer. It appears that the landscaping plantings may function like a dam. If necessary, provide a space where the bottom of the swale is proposed.

On sheet C4.1, there are two locations to check:

(a) The.western one next to the right-of-way line appears to drain across the sidewalk. The sidewalk needs to remain slip resistant.

(b) The eastern one is at the east access to the phase two building. In lieu of draining down the sidewalk, there should be a cross slope to drain away from the building and off of the sidewalk.

CNISoils: The derivation of the curve numbers indicate only two basins, on and off site. The calculations indicated that there are two offsite basins. If the CN values are to be different, show the breakdown(s).

Where perc is to be used in the design of the stormwater facility, a DRI test is required to be done within the proposed stormwater at the bottom of pond elevation. Provide DRI test for both ponds. A factor of safety of two on the perc rate is required to be used. Provide the support calculations, i.e., MODRET or other.

Wherever the concrete sidewalk crosses a vehicular use area, add WWF, fibermesh, or approved equivalent.

Provide terminus or detectable warnings at sidewalk ends for the visually impaired.

Add the detectable warning detail (2008 FDOT, Index 304). Domes to be aligned in the direction of travel.

(ZNI 2-01 7) Page 6 of 10

(a) The cross-slope of the shoulders shall not be steeper than 0.06 feet per foot.

(b) The slope of the area within the roadside clear zone shall not be steeper than six feet horizontal to one foot vertical (6:l).

(c) Outside clear zone, all slopes within the County rights-of-way shall be a maximum of 4:l.

(d) Ditch bottoms should be at least two-feet wide and can be flat or gently rounded.

(27) Provide an Agent of Record for engineer and also for the developer if they are not the property owner.

(28) On the cover sheet, change the title of the "allowed" column to "minimum1maximum" and correctly fill it, or remove altogether.

(29) As it appears that all new improvements will not be constructed for occupancy at the same time, clearly indicate phase lines. Please take into consideration that the phase will need to be completely built for final engineering inspections, and the infrastructure must be adequate to support that phase.

(30) The minimum radii for entrances are 25 feet. Please correct the driveways as needed.

(31) On the north drive, where it is one-way, restrict the southern radius to preclude entrance from the south (right out only).

(32) Minimum stall depth for 60 degree spaces is 21 feet. Minimum stall width is 10.5 feet. Minimum aisle width is 18 feet. Correct the spaces along the southern portion of the one-way drive. Remove or correct the northern Americans with Disabilities Act (ADA) parking space so that it conforms.

(33) Loadinglunloading area of 12 x 50 is required for all commercial sites. If this can be accomplished using a standard parking space, place a note stating such on the plans. Show the arc-turn of the truck to and from the loading zone.

(34) Explain the note "grass parkinglgrass drivelno walk as an alternative". Any off-street parking area shall be graded for proper drainage and shall be surfaced so as to provide a durable and dustless surface including, but not limited to, a gravel, concrete, or bituminous concrete surface, and shall be so arranged as to provide for orderly and safe parking and storage of vehicles. All drive aisles must support a fire truck. If the drivelparking aisle is proposed to not be asphalted, provide a detail of the alternative. Simply leaving dirtisand is not an alternative.

(35) Please add a note that there will be no light spillage or glare beyond the project site.

(36) Clearly list the square footage for each phase, on each floor, and the totals.

(37) The pine or palm proposed to be removed on the north side of the property must be shown as replaced. The proposed landscaping will be fine, but please add the attached chart.

(38) Show the tree protection locations for the trees to be retained and provide a note that nothing can be dumped or placed under the dripline during construction.

(ZNI 2-017) Page 7 of 10

All punk, ear, camphor, chinaberry, and mimosa trees are required to be removed because they are invasive. They do not have to be replaced.

Use the approved landscape chart which shows common and botanical names, height, caliper, drought tolerance, and whether a species is native.

Provide calculations to show the percentage of native plants and drought tolerant plants.

Show the detail for heating, ventilating, and air conditioning units' six-feet tall masonry wall screen.

A minimum of one species per five trees proposed is required. When forty or more trees are required, the minimum number of species is eight.

Palm trees may be substituted for up to 30 percent of the required shade trees at a rate of three palms for one shade tree, clustered eight feet on center, and display ten feet clear trunk.

No one plant species of shrubs or groundcover plants shall be more than 25 percent coverage of overall landscape area. Do not count the Bahia grass with groundcover; it is considered sod. Provide square footage for the shrubs also so that an equivalent comparison can be made. More species of shrubs and groundcover probably will be needed so that the maximum is not exceeded.

No more than 30 percent of landscaped areas may be grass; the balance must be shrubs or groundcover.

The areas to be covered in Bahia grass appear to exceed the maximum coverage; please correct and provide calculations.

A minimum.of 30 percent of the plant materials, other than trees and turf grass, used to fulfill the landscape requirements shall be native Floridian species. None of the species proposed are native; please correct.

All rows of parking shall have a terminal landscaped island (8' x 20') at each end, measured from the interior curb edges of the island. Some of the islands do not meet the measurements; please correct.

Each single, island shall have one shade tree, supplemented by shrubs, dwarf shrubs, and/or groundcover. All plants must be appropriate for the planting space; the Quercus virginiana will likely grow too large for the islands; please choose a different species.

The building perimeter shall be landscaped with an area, equal to ten percent of each building ground level floor area; the area will be a minimum of five-feet wide and shall include shade trees and/or palms, shrubs, and groundcover. Each building requires a minimum of two trees in its perimeter area. Fifty percent of the building perimeter is required to be landscaped with trees, shrubs, and groundcover. Correct the plantings around the addition(s).

Please indicate each buffer type on the plans, e.g., Type B with a typical cross section for each buffer type.

What will be used to provide the screening? If the continuous row of shrubs will be used, amend the plant table to show the height at planting as six feet; unless a variance to allow shorter shrubs is granted.

On the east and west sides, there are areas where the tree spacing is too great; please correct.

Water Management Systems are permitted within a required buffer provided that it does not exceed 50 percent of the square footage of any required side, rear, or front yard landscape buffer and does not exceed, at any location within the buffer, 70 percent of the buffer width. A minimum

(ZNI 2-01 7) Page 8 of 10

five-foot wide level planting area shall be maintained between the retentionldetention pond or swale and the public right-of-way or adjacent parcel. The swale on the east exceeds the maximum. Staff would support a variance to allow it to do so.

(56) Trees must be planted at the rate of one tree per 50 linear feet of pond bank, but may be clustered or grouped to soften the visual edge. These trees are in addition to those required for the buffer. Water tolerant species are suggested.

(57) Provide a 1" = 200' drawing. Map is needed of the property boundary with lots, tracts, roadways, lift stations, buildings (with suites, units), and parking area only. The labeling should consist of lotlblock numbers, tract designation, and reserved street names, no geometry or additional labeling please.

(58) Provide a CAD file(s) set to Florida State Plane Coordinates - NAD 1983 Harn Florida West (Feet) with buildings and building numbers (apartment, condo, suite, etc); road centerlines with reserved names; lift stations, fire hydrants, lots and lot numbers, tracts and tract names (if applicable).

(59) The applicant shall provide a copy of the Environmental Resource Permit or permit exemption from the Southwest Florida Water Management District for the file of record prior to issuance of the Site Development Permit.

(60) DDCVA and fire hydrant supply line must be a minimum of eight inches in diameter.

(61) Sheet C3.2: the installation of sidewalk should be continued north on Barker Drive and then east on Grey Street. All sidewalk ramps shall be per FDOT standards for ADA compliance.

(62) Sheet C3.2: the crosswalk on Barker Drive should be ladder type per FDOT standards. W l l - 2 with W16-7P signs are required at the crosswalk.

(63) Sheet C3.2: the north driveway on Barker Drive; remove the R5-1 Do Not Enter sign from the back of the stop sign. Such posting is not permitted per the manual on Uniform Traffic Control Devices.

(64) Sheet C3.2: the north driveway on Barker Drive, add R6-I RIL sign on top of the R5-1 Do Not Enter sign on the south side.

24. Prior to issuance of the first CO or Certificate of Completion, provide, proof of public notice (affidavit of publication and affidavit of mailings, pursuant to the LDC, Section 306.3.E.2.e) to Zoning and Site Development.

25. Unless otherwise approved by the Emergency Services Director, when the development is record platted, or where a plat is not required, prior to the issuance of the first Building Permit, the development shall be included into a Pasco County Municipal Fire Service Taxing Unit to provide fire protection. The developer shall submit a petition for inclusion into the Pasco County Municipal Fire Service Taxing Unit at the time of record plat submission, or when no plat is required, prior to the issuance of the first Building Permit. In no case shall a Building Permit be issued until such a petition has been received by the Emergency Services Director.

26. If a Pasco County Global Positioning System (GPS) network point is located within the boundary of the site or within 50 feet of the same, the point shall be re-established using GPS methods and "Blue Booked" prior to the issuance of any Building Permits or the recording of any plat. Proof of the said Blue Booking shall be submitted to the County Surveyor prior to the issuance of the said permit or the recording of the said plat. If it is discovered that the said point has been destroyed by construction, then the applicantldeveloper of the land will be responsible for payment to Pasco County in the amount of $5,000.00 each.

27. The ownerldeveloper shall arrange for a final site inspection approval by the Engineering Services Department prior to the issuance of the Certificate of Occupancy (CO).
