"David Bosman - KWC" KWC is currently looking into a couple options to address the high water table issue. KWC is going to raise the pad elevations utilizing utility spoils and in conjunction will specify a concrete slab in the crawl space. Other mitigation measures to address the water issue will be provided in the details on the plans, such as water proofing retaining walls, plastic sheating, etc. 1164

7106 S Mentor Ave #200

MBPro Response: The representative of the Geotechnical Engineer should check the bottom of the excavations for disturbed subgrade soils. Where present, it is recommended to remove all disturbed soils from the bottom of the excavations using a flat bottom bucket (toothless), a dozer blade or similar equipment. Following bottom approval, the geotextile fabric should be placed and covered with a minimum of 6 inches of one-inch crushed rock (Greenbook specifications or equivalent). The crushed rock thickness should be increased, as necessary, where the conditions dictate, and should be extended at least 6 inches above groundwater. Where “pumping conditions” have developed, the crushed rock thickness should be increased to about 12 to 15 inches, depending upon the conditions observed in the field. The top of the rock should be covered with geotextile fabric before placement of the onsite sand. Where water is present at the bottom of the excavations, the geotextile should consist of a non-woven fabric such as Mirafi 1120N (or approved equivalent), which can serve as a separation, a stabilization and a drainage fabric, since a woven fabric may float and impede compaction because of its relative imperviousness. For the locations above groundwater, the geotextile may consist of woven fabric such as Mirafi 500 X or approved equivalent. An alternative to placement of rock and fabric would be to lower the groundwater by 18 inches during the placement of the first 15 inches of soil backfill. MBPro 5/6/22 1166

The recommendations for subgrade preparation including the placement of crushed rock enveloped in fabric should only be performed in areas of visible standing water and where compaction is not feasible (currently Bldg Pads 4,5,6,7 to the extent of where the water is visible).

The crushed rock layer should extend above the water table level prior to the placement of ﬁll material.

Follow recommendations for Gravel thickness as described in RFI 59.1 Response #1 #2:

TenCate develops and produces materials
that function to increase performance,
reduce costs and deliver measurable results
by working with our customers to provide
advanced solutions.

The Difference Mirafi
® N-Series Nonwoven
Geotextiles Make:
• Construction. Mirafi® N-Series polypro-
pylene nonwoven geotextiles easily con-
form to the ground or trench surface for
trouble free installation.
• Strength. Mirafi
® N-Series geotextiles
withstand installation stresses with high
puncture and tear resistance.
• Drainage. High permittivity properties pro-
vide high water flow rates while providing
excellent soil retention.
• Environmental. Mirafi
® N-Series geotex-
tiles are chemically stable in a wide range
of aggressive environments.
• Cost Effective. Mirafi
® N-Series geotex-
tiles provide economical solutions to many
civil engineering applications including a
cost effective alternative to graded aggre-
gate filters.

APPLICATIONS
Mirafi
® N-Series nonwoven geotextiles are
used in a wide variety of applications includ-
ing soil separation and drainage applications.

Lightweight nonwovens are predominantly
used for subsurface drainage applications
along highways, within embankments, under
airfields, and athletic fields. For these drain-
age structures to be effective, they must
have a properly designed protective filter.

Mirafi
® N-Series nonwoven geotextiles elimi-
nates the challenge of determining the
aggregate gradation required to match soil
conditions, finding a convenient and econom-
ical source of a specific aggregate, transport-
ing and placing graded aggregate, and assur-
ing that the constructed in-place drainage
system provides effective filter performance.

Heavyweight nonwovens are used in critical
subsurface drainage systems, soil separa-
tion, permanent erosion control, and
geomembrane liner protection within land-
fills. These geotextiles provide the required
strength and abrasion resistance to with-
stand installation and application stresses to
create an effective, long term drainage solu-
tion.

INSTALLATION GUIDELINES*
French and Trench Drains Geosynthetic Placement
Cut geosynthetic to proper width prior to
placement. Width should be enough to con-
form to the trench perimeter with at least a
6in (15cm) top overlap. Place the geosynthe-
tic roll over the trench, and unroll enough
geosynthetic that the geosynthetic can be
placed down into the trench. Anchor the
edges of the geosynthetic with heavy objects
to prevent the geosynthetic from falling into
the trench. Where overlaps are necessary
between rolls, allow for 3 ft (1m) overlap
from the upstream to the downstream roll.
* These guidelines serve as a general basis for installation.

Detailed instructions are available from your TenCate® rep- resentative.

Re: Victorville Wellness Center
Dear Jay,
Thank you for contacting Griffin. We are pleased to submit our proposal for the above referenced project. This proposal outlines the proposed equipment and materials, price of the system, and any Contractor assistance that will be needed.

Project Information________________________________________________________________________ The site is located in Victorville, CA and consists of 350’ of pipeline installation.

Excavations for the work will vary between EL 2691-2700. The groundwater is at EL 2699, and the soils consist of well and poorly graded sands with clayey sand. If the granular soils are not dewatered prior to construction then the excavations will flood and become unstable and unsafe.

The assumed project parameters can be summarized as follows:

*bgs – Below Ground Surface. Pipe excavations include approximately 1’ of over-excavation. ***Listed static water level is based on the water table elevation shown on sheet no. 3 in the referenced precise grading plans. Actual encountered groundwater elevation may vary.

Our proposal is based on the information provided, specifically:
• Geotechnical Investigation Report provided by Merrell Engineering Company, Inc. (12/11/2020; M.J. Project No. 2102.041.500)
• Infiltration Report provided by Merrell Engineering Company, Inc. (11/09/2020; M.J. Project No. 2102.041.500) • Precise grading plans provided by the City of Victorville Engineering Department (01/03/2022; WDID No. 6B36C396947)
• Wet utility plans provided by Victorville Engineering Department (10/08/2021; WDID No. 6B36W00481) • UNE interceptor plans (addendum 4) provided by Victor Valley Wastewater Reclamation Authority (11/2013, Project No. 135-09065-11001)10th street sewer lift station plans provided by the City of Victorville Engineering Department (10/06/2015; Drawing No. SP-735)

Scope of Work_____________________________________________________________________________

Based on the above information, Griffin will provide and install the following scope of services:
• Type of proposed System: A deep well dewatering system along one side of the pipeline trench. • Installation Method: Wells will be drilled up to 40’ deep, utilizing Griffin’s bucket auger drilling rig to drill up to a 30” diameter borehole. Deep wells come complete with screen, casing, riser pipe and a select filter pack. • Pumping System: Submersible turbine pumps within each well. Pumping system comes complete with a check valve, butterfly valve, swing hose, control panel and motor cable to within 10’ of the borehole at the surface. • Power Requirement: Minimum, 460V, 3Ø, 70amps
• Discharge: Up to 400LF of discharge pipe/hose routed to a mutually agreed upon location. • Removal & Demobilization: Upon completion of dewatering, Griffin proposes to remobilize to the site and remove all Griffin materials and return them to the nearest Griffin yard.

Assumptions:
• It is assumed that all of the wells can be completed under one mobilization. • Griffin is assuming a static water level (SWL) of EL 2699 across the project area. • Upon completion of a series of wells, Griffin recommends performing a pump test to verify Griffin’s assumptions on the aquifers characteristics and system performance. • Griffin is assuming a permeability range of 0.1-0.3 ft/min for this site. • It is assumed that water bearing sands will be encountered to a depth of 40ft in the areas requiring dewatering. • No guarantees are made regarding the adequacy of this system. Griffin will share our full dewatering plan once a commitment is made.
• Subcontractor has not independently verified subsurface conditions and is relying on the continuity and accuracy of the geotechnical report

Attached please find the following:
• Attachment A – Pricing
• Attachment B – Contractor’s Obligations
• Attachment C – Terms & Conditions

2.0 Project Parameters

2.1 Geology and Groundwater

Based on the Geotechnical Engineering Investigation by Merrell Engineering Company, Inc. (dated December 11th, 2020) the local hydrogeology can be summarized as follows:

Site Hydrogeology:

- Existing Ground Elevation: EL 2702-2708
- Groundwater Depth: 3-9 ft bgs (EL 2699)
- Boring B1 is considered emblematic of the site soil conditions and is included in Attachment 01.

2.3 Proposed System

Deep Well System:

Griffin will install a deep well dewatering system to aid in dewatering for the above excavations. Griffin will install up to five (5) wells along one side of the VVWRA pipeline replacement at mutually agreed locations (refer to attached Dwg 01 for proposed well locations). The wells will be drilled utilizing Griffin’s bucket-auger drilling method to advance a nominal 30” diameter borehole to a depth of ±40 ft, or refusal, whichever is encountered first.

Upon completion of the borehole, Griffin will set a 12-inch well complete with up to 20 ft of standard PVC mill-slot screen (50 slot) and 20ft of PVC casing and select filter pack (#5 Rock or similar) within the annulus of the borehole (Dwg 02).

Once the well has been completed, Griffin will begin the development procedure. The well will then be developed utilizing the air-lift method.

1203

5 Victorville Wellness Center, Victorville, CA
Upon completion of the deep wells, Griffin will furnish and install a well pump system consisting of up to five (5), 10 HP, 460v, 3 phase electric submersible pumps. Each pump will be equipped with valves, fittings, and motor cable to a control panel within 10ft of the well head that will connect to Griffins electric distribution cable from the power source to the control panels.

Griffin will also provide generators to power the dewatering system. The generators would consist of the following items:
• 1 Primary Generator (125KVA) Triple Shift – Estimated fuel consumption at 4.5- 6.8 GPH – Fuel not included
• 1 Standby Generator (125 KVA) Single Shift
• 1 Auto Transfer Switch
• 1 Automatic overflow/turn-on float panel alarm (in the case water treatment tanks overflow) • 1 (600 gallon) double-wall fuel tank
• 3 Spill berms

Effluent from each well will be through a common 12” discharge manifold (HDPE) laid on grade directed to a mutually agreed upon location. The discharge line will be equipped with a totalizing flow meter to track discharge volumes. All burials and crossings will be completed by others.

3.0 Maintenance and Removal

After the installation is complete and the system is operational, Griffin will provide training of the contractor’s personnel in the ongoing operation, maintenance, inspection and reporting of the dewatering system. Upon completion of the dewatering portion of the project, Griffin will then remove and return the above system to our yard.

4.0 Dewatering Discharge Analysis

Griffin has utilized analytical calculations based on the available information and estimated the dewatering system discharge flow rate. This section of the submittal includes the details of our analysis.

4.1 Parameters and Assumptions:

Griffin evaluated the dewatering at this site utilizing both the Geotechnical Report and the provided plans and came up with the following base assumptions regarding the project and aquifer at this site:

- Excavation Dimensions: 350LF
- Excavation Depth: Approximately EL. 2693-2694.5.
- Excavation Method: Trench Boxes
- Groundwater Table: Assumed EL 2699.
- Aquifer Bottom: Approximately 40 ft below grade (EL 2665; top of the finer clayey sand unit). - Hydraulic Conductivity: Assumed to be near 0.1 – 0.3 ft/min based on the provided gradations. o Permeability Estimated using both Hazen and Prugh Methodology. Permeability was also evaluated using the HydrogeosieveXL software by the University of Kansas.

Given the above information, Griffin analyzed the dewatering for the excavations utilizing a series of analytical equations based on the Dupuit assumptions for unconfined aquifers:

1204

6 Victorville Wellness Center, Victorville, CA
Unconfined Trench Equation:

𝑄 = 𝐾(𝐻2 − ℎ𝑤2 )
458 ln 𝑅𝑜/𝑟𝑤
+ 2 [𝑥𝐾(𝐻2 − ℎ𝑤2 )
1440𝑅𝑜
]

Where K = Hydraulic Conductivity (gpd/ft2)
H = Saturated Thickness (feet)
B = Confined thickness
hw = Saturated Thickness in dewatered state (feet)
Ro = Radius of Influence (feet)
rw = Radius of Well (feet)
Q = Flow (Gallons Per Minute)
X = Trench Length (feet)

The radius of influence of a well can be estimated using an empirical relationship developed by Sichart and Kryieleis which gives Ro as a function of drawdown:

𝑅𝑜 = 2.06(𝐻 − ℎ𝑤)√𝐾 + 𝑟𝑤

By looking at the entire dewatering system/project site as a single lar ge well with a radius r w, a reasonable approximation of the required flow to dewater a site can be made.

For this project site, Griffin has estimated flows of approximately 1616 gpm, depending on the actual permeability and saturated thickness encountered. Griffin’s analytical calculations are provided below. 1205

Limitations
The conclusions and recommendations presented in the submittal are based upon the assumption that the below-surface soil conditions do not differ substantially from those presented in the referenced Geotechnical Exploration Report ( Merrell Engineering Company, Inc.) and are also based upon the premise of competent monitoring and testing (by others) during the dewatering operation. It is important to recognize that subsurface conditions can vary significantly over short distances and be different from those assumed in this report. If unanticipated conditions are encountered, Griffin will re-evaluate the conclusions and recommendations in this submittal accordingly.

The dewatering services provided in connection with this project were performed in a manner consist ent with the level of care and skill ordinarily taken by a dewatering firm. The opinions and conclusions presented in the submittal are based solely upon the information provided to Griffin. No other representation, warranty, or guarantee is intended by th is submittal. In addition, no liability is assumed by Griffin for any actual/alleged settlement or subsidence of adjacent structures.

1228
CertainTeed – the name that contractors have come to associate with the industry’s broadest line of high-quality PVC well products – is also the industry leader in high performance slotted well casing. Using new manufacturing technology , slotted casing can now be produced with open areas and efficiencies that rival those of other screens, often at a fraction of the cost. Combine PVC screens with PVC well casing for the ultimate corrosion-resistant, low-maintenance water well!
A Size and Joining System for Every Application
Slotted casing can be produced in sizes from 2" all the way up to the largest commercially available PVC well casing product (17.4" O.D.), in a variety of wall thicknesses
and strengths to suit virtually all applications:
• Domestic
• Irrigation
• Municipal
• Aquifer Storage and Recovery
• Environmental
CertainTeed also offers a choice of joining systems:
traditional solvent-weld or the contractor-proven,
all-weather Certa-Lok
™ mechanical joint.

Slot Width Selection
A wide selection of precision-machined factory slot designs (.010"-.125") with closely spaced inlet openings provides for uniform development over the length of the screen and proper stabilization of the gravel pack.

Long Life
Well rehabilitation costs are minimized, as PVC screens are inherently more resistant than conventional steel products to clogging and encrustation. PVC also outperforms stainless steel in highly corrosive environments, at a fraction of the cost. All screens are manufactured from PVC casing that is listed by NSF International as safe for use with potable water.

Single Source for All Y our Well Product Needs
No more unloading, local-machining, and repackaging required. With CertainTeed, the industry’s best slotted casing is shipped ready to use – no field fabrication required – along with your other PVC well product needs, including solid casing, drop pipe for submersible pumps, and a variety of fittings.

Notes: 1. As a general rule, Flow Rating (GPM/ft) in a gravel-packed well = O.D. Open Area (in2/ft)* (.50 blockage factor)* (.31 conversion factor) at an entrance velocity of 0.1 fps.

2. Open area percentage varies from 2% to over 20%, depending upon casing size and slot width.

3. CertainT eed can supply a detailed Engineering Specification for any of the products shown, or for special made-to-order products.

4. Slots can often be lengthened on thick-wall products to provide additional I.D. penetration; revised specifications showing increased open area are available upon request.

5. Standard slot spacing = .25". Smaller and wider spacing is available - wider spacing is recommended for slot widths of .100” and above.

6. Specifications subject to change. Standard manufacturing tolerances apply.

7. All dimensions are in inches.

This chart illustrates standard manufacturing capabilities only. Not all products shown are routinely stocked – call for availability.

Slotted PVC casing is also ideal for use as underdrain pipe.

Applications include, but are not limited to:
• Leachate collection systems for solid waste landfills • Drainage and dewatering applications
• Mining heap leach projects
PVC underdrain pipe is supplied with precision-machined slots, which provide greater intake capacity and continuous, clog-resistant drainage of fluids, as compared to standard round-hole perforated pipe. Slotted underdrain reduces entrance velocity into the pipe, thereby reducing the possibility that solids will be carried into the system. Slot rows can generally be positioned symmetrically or asymmetrically around the pipe circumference, depending upon the application. Outside diameters are generally the same for PVC and non-corrugated polyethylene (HDPE) pipe. However, the HDPE pipe must be extruded with a thicker wall (and therefore a reduced cross-sectional flow area) to obtain a comparable stiffness rating. 1230

Subject: (URGENT) Additional Wells/Pumps Installation is needed

Hello Team,

The dewatering initiated on 6/10/22 is hampered by the clay layer found on 6/7/2022 at 29’ on per our NOD #06 as discussed.

The additional wells and pumps are to be installed to overcome the choking factors of the clay layer in the budget range of $160,000 for the additional drilling, well development, pump installation, bigger generators with a backup, and fuel tanks.

We are in the works of building this proposal in the Gordian system for their review, meanwhile, the installation of the wells and pumps is to begin as early as tomorrow.

Please advise.

Thanks,

Scope of Work_____________________________________________________________________________

Based on the above information, Griffin will provide and install the following scope of services:
• Type of proposed System: A deep well dewatering system along one side of the pipeline trench. • Installation Method: Five additional wells will be drilled in between existing wells up to 40’ deep, utilizing Griffin’s bucket auger drilling rig to drill up to a 30” diameter borehole. Deep wells come complete with screen, casing, riser pipe and a select filter pack.
• Pumping System: Submersible turbine pumps within each well. Pumping system comes complete with a check valve, butterfly valve, swing hose, control panel and motor cable to within 10’ of the borehole at the surface. • Power Requirement: Minimum, 460V, 3Ø, 150amps
• Discharge: Up to 900LF of discharge pipe/hose routed to a mutually agreed upon location. • This header pipe will be placed along side the existing discharge header. • Removal & Demobilization: Upon completion of dewatering, Griffin proposes to remobilize to the site and remove all Griffin materials and return them to the nearest Griffin yard.

Assumptions:
• It is assumed that all of the wells can be completed under one mobilization. • Griffin is assuming a static water level (SWL) of EL 2699 across the project area. • Upon completion of a series of wells, Griffin recommends performing a pump test to verify Griffin’s assumptions on the aquifers characteristics and system performance. • Griffin is assuming a permeability range of 0.1-0.3 ft/min for this site. • It is assumed that water bearing sands will be encountered to a depth of 30ft in the areas requiring dewatering. • No guarantees are made regarding the adequacy of this system. Griffin will share our f ull dewatering plan once a commitment is made.
• Subcontractor has not independently verified subsurface conditions and is relying on the continuity and accuracy of the geotechnical report

All,

The transportation will need to be a supplemental work order to the ACI phase 1 contract. The City cannot contract directly with a transportation company quickly enough to meet the July 1 deadline. This is 1 week from today. This needs to be arranged ASAP.

Submitted By:

Brian Gengler, City Engineer
Subject:

Initiate the Annexation of Tract No. 20275 into Drainage Facilities Assessment District No. 1 and Landscape Maintenance Assessment District No. 6 Recommendation:

That the City Council:
(1) Approve Resolution No. 22-031 to initiate proceedings to annex Tract No. 20275 into Drainage Facilities Assessment District No. 1;
(2) Approve Resolution No. 22-062 to initiate proceedings to annex Tract No. 20275 into Landscape Maintenance Assessment District No. 6;
(3) Approve Resolution No. 22-063 to preliminarily approve the Drainage Facilities Assessment District No. 1 Engineer’s Report;
(4) Approve Resolution No. 22-071 to preliminarily approve the Landscape Maintenance Assessment District No. 6 Engineer’s Report; and
(5) Approve Resolution Nos. 22-072 and 22-073 setting a public hearing date of September 6, 2022.

Fiscal Impact:

There is no fiscal impact associated with the approval of resolutions listed above.

Maintenance and servicing of the drainage and landscaping improvements in future years will be covered by the subsequent annual assessments levied on these and other properties within the boundaries of their assigned districts.

Background:

The property owner for Tract Map No. 20275 (Tract 20275) has petitioned the City to annex the tract into the City-Wide Drainage Facilities Assessment District No. 1 (DFAD 1) and the Landscape Maintenance Assessment District No. 6 (LMAD 6) in order to comply with the Conditions of Approval for Tract 20275. Tract 20275 is located at the southeast corner of Monte Vista Road and Luna Road. Tract 20275 is a proposed 135- lot single-family subdivision that includes drainage and landscaping improvements within 1327
2 6
9 4
the tract. This annexation will provide for the perpetual maintenance and servicing of the drainage and landscape improvements by means of a new annual assessment to each property within Tract 20275.

Discussion:

The City formed DFAD 1 and LMAD 6 pursuant to the Landscaping and Lighting Act of 1972, Streets and Highways Code section 22500 et seq. (the Act); the applicable provisions of Proposition 218 (Article XIIID of the California Constitution, hereinafter referred to as the “California Constitution”); and Government Code section 53753, part of the Omnibus Act.

DFAD 1 and LMAD 6 allows the City to collect assessments for maintaining and servicing the drainage and landscaping improvements within these districts. Assessments are levied and collected annually according to the special benefits received by properties from the improvements provided by the City. The formation documents of DFAD 1 and LMAD 6 contain a mechanism permitting the annual assessment amount to be adjusted from time to time, commensurate with increases in the costs to maintain the drainage and landscaping improvements.

A public hearing regarding the amount of the assessments is conducted annually by the City Council. In accordance with the special benefit calculation contained in the annual Engineer’s Report, the total assessments for DFAD 1 and LMAD 6 are equally distributed amongst all the parcels within the district boundaries. The current annual assessment amounts per parcel are $204.21 for DFAD 1 and $144.70 for LMAD 6. Both districts are adequately funded to perform all required maintenance and servicing of the proposed improvements for Tract 20275.

Sections 22605 through 22613 of the Act, as amplified by the California Constitution and Government Code section 53753, provide procedures for annexation of new territory into an existing assessment district. In order for Tract 20275 to become subject to the annual assessments applicable to DFAD 1 and LMAD 6, and to receive the level of perpetual maintenance provided to other properties within those assessment districts, annexation to DFAD 1 and LMAD 6 is required.

For this annexation to occur, the City Council must approve a series of eight resolutions at two City Council meetings. Resolutions Nos. 22-031 and 22-062 will initiate annexation, request the City Engineer’s Reports, and file with the City Clerk for City Council consideration. The Engineer’s Reports are required by the Act and include the estimated costs of the annexation, a description of the improvements and special benefits to be received by the parcels, a determination of the estimated amounts of the assessments to be levied upon the properties proposed to be annexed, an annexation map, and other information as required by Article 4 (commencing with section 22565) of the Act and the California Constitution, as amplified by Government Code section 53753.

If the aforementioned resolutions are approved, the Engineer’s Reports would be preliminarily approved by Resolution Nos. 22-063 and 22-071, which would also declare 1328
2 6
9 4
the City Council’s intent to annex Tract 20275 to DFAD 1 and LMAD 6. At this same meeting, a fifth and sixth resolution will also need to be approved by the City Council to set a public hearing of September 6, 2022 and order the mailing of the public hearing notices and assessment ballots to the property owners within Tract 20275, no less than 45 days prior to said public hearing.

During the September 6, 2022 meeting, the City Council would then conduct the public hearing and count the assessment ballots submitted. If at the end of the public hearing, the ballots cast in favor of the annexation exceed the ballots cast in opposition, the City Council may proceed to annex Tract 20275 to DFAD 1 and LMAD 6, approve the Engineer’s Reports for each assessment district, order the assessments to be levied, and complete the subsequent annexations by approving the final resolutions.

Therefore, staff recommends that the City Council approve Resolution No. 22-031 to initiate proceedings to annex Tract 20275 into DFAD 1 and Resolution No. 22-062 to annex into LMAD 6, approve Resolution Nos. 22-063 and 22-071 to preliminarily approve both districts Engineer’s Reports, and approve Resolution Nos. 22-072 and 22-073 setting a public hearing date of September 6, 2022.

Staff remains available for any questions Council may have.

Introduction
The City of Victorville (“City”), under the provisions of the Landscaping and Lighting Act of 1972, Part 2 of Division 15 of the California Streets and Highways Code (“1972 Act”) established the assessment district designated as:

DRAINAGE FACILITIES ASSESSMENT DISTRICT NO. 1
(hereinafter referred to as “ DFAD No. 1 ” or “District”). Pursuant to the provisions of the 1972 Act and in compliance with the substantive and procedural requirements of Article XIIID of the California State Constitution (the “California Constitution”), the City Council of the City of Victorville (“City Council”), proposes to annex Tract No. 20275, expanding the improvements to be provided and maintained within the DFAD No. 1, and to conduct a protest ballot proceeding for special benefit assessments to be levied and collected annually on the parcels within the Annexation Territory in order to fund in whole or in part the maintenance and operation of certain public improvements that may include, but is not limited to landscape crews, basins and appurtenant facilities that provide special benefits to those properties commencing in Fiscal Year 2022/2023.

As required pursuant to Chapter 1, Article 4 of the 1972 Act, this Drainage Facilities Assessment District Engineer’s Report (“Report”) shall serve as the detailed engineer’s report for the annexation of Territory to Drainage Facilities Assessment District No. 1, for Tract No. 20275 (hereafter referred to as the, “Annexation Territory”) and the establishment of annual assessments to be levied and collected upon properties within the proposed Annexation Territory in connection with the special benefits each property receives from the maintenance and servicing of the improvements to be provide d by the C ity through the District. The assessments described herein will provide an annual funding source to adequately support the ongoing maintenance, servicing, operation, and incidental expenses associated with the drainage landscaping and irrigation improvements, and appurtenant facilities and amenities that benefit the identified properties within the Annexation Territory. The Annexation Territory as shown on the diagram contained in Part IV of this Report, encompass all lots and parcels of land within a defined area of the City that will receive special benefits from the ongoing servicing, maintenance, operation, and incidental expenses associated with the improvements to be funded by the assessments. Parcels within the Annexation Territory will be assessed for their proportionate special benefit of the shared drainage landscaping and irrigation improvements and appurtenant facilities.

The City Council of the City of Victorville adopted its General Plan with various elements to provide guidelines for o rderly development of property within the City . The City Council further adopted ordinances and regulations governing the development of land providing for the installation and construction of certain landscaping and appurtenant facilities to enhance the quality of life and to benefit the value of property.

The requirement for the installation of landscaping, streets and appurtenant facilities is a condition of development provided for in the City's Subdivision Ordinance and is a requirement fo r issuance of a permit for construction of commercial, residential, and planned unit development. These improvements generally include but are not limited to street lights and related equipment and fixtures; various landscape materials such as trees, turf, shrubs, vines, and ground cover; irrigation and drainage systems; structural amenities such as monuments, block walls, retaining walls, or other fencing; hardscapes including mulch, trail and path surfaces, stamped concrete and pavers; recreational amenit ies such as benches, picnic facilities, play structures; signage, and related appurtenances.

The installation of landscaping and appurtenant facilities is the responsibility of the sub-divider or other development/applicant, triggered by the approval of a tentative subdivision map or other development 1336

Annexation of Tract No. 20275
Fiscal Year 2022/2023

Page 2 ends

application. After installation, it is City policy that the servicing, operation, maintenance, repair, and replacement of landscaping and appurtenant facilities in turn become the fiscal responsibility of the properties that specially benefit from the facilities.

HISTORICAL BACKGROUND
The residential subdivision plans for the tracts within DFAD No. 1 were submitted to the City by developers and were approved with certain conditions. One such condition required a means to fund the perpetual maintenance of landscaping within the public right-of-ways and dedicated easement areas. In order to meet this con dition, the developer, as sole -owner of the subdivision property, petitioned the City to form an assessment district. The DFADs were formed by City Council Resolutions in accordance with the Landscape and Lighting Act of 1972, which is Part 2, Division 15 of the California Streets and Highways Code, in order to provide a funding source for the administration, operations and maintenance, and servicing of the landscaping within the District. Each parcel within the DFADs is assessed at a rate equitable to the budget, not exceeding the maximum allowable rate. Future improvement parcels are assessed $1.00 annually until such time the improvements are constructed.

In 2003, Drainage Facilities Assessment District No. 1 was formed by Resolutions 03 -046, 03-047, 03-048 and 03-049. As of Fiscal Year 2022/23, there are thirty-two (32) tracts, and several unimproved parcels of vacant land in the District. Existing drainage facilities improvements are 566,998.40 square feet to include detention basins, drainage channels and perimeter landscaping that is located throughout the City.

ANNEXATION TERRITORY
The Annexation Territory consists of all lots and parcels of land within the planned development identified as Tract No. 20275 which will develop out to 135 residential units.

This Report has been prepared pursuant to the provisions of the California Constitution and the 1972 Act and shall serve as the detailed engineer’s report regarding the annexation of the designated Annexation Territory into the Victorville Drainage Facilities Assessment District No. 1. The proposed assessments will be levied on the properties therein commencing in Fiscal Year 2023/2024 for the proportional special benefits the properties will receive from the ongoing maintenance and servicing of the improvements associated with and/or resulting from the development of properties within the Annexation Territory.

The City Council proposes to annex the Annexation Territory into the District as Tract No. 20275, and to levy and collect annual special benefit assessments on the County tax rolls to provide ongoing funding for the direct expenditures, incidental expenses, and fund balances that are necessary to service and maintain the landscaping improvements associated with and resulting from the development of property within the Annexation Territory. The improvements described in this Report for the Annexation Territory are based on the initial improvement and development plans for Assessor Parcel Number 3133-111-01-0000 and by reference those plans, and specifications are made part of this Report.

The estimated budget provided herein is based on the City’s estimate of the Annexation Territory expenses for local improvements and services in the Annexation Territory. The resulting annual assessments a re calculated utilizing the method of apportionment established under Part II Method of Apportionment and are made pursuant to the 1972 Act and the substantive and procedural provisions of the California Constitution.

The word “parcel,” for the purposes of this Report, refers to an individual property assigned its own Assessor’s Parcel Number (APN) by the San Bernardino County Assessor’s Office. The San Bernardino County 1337

Auditor/Controller uses Assessor’s Parcel Numbers and specific Fund Numbers to identify properties to be assessed on the tax roll for the special benefit assessments.

PROCEEDINGS AND REPORT CONTENT
This Report specifically addresses the proposed annexation of Territory, the resulting boundary change, the various improvements within the Tract, and the proposed assessment to be levied in connection with the special benefits the properties will receive from the maintenance and servicing of the improvements based on the estimated operating and maintenance expenses. The proposed annual assessments to be levied on properties within the Annexation Territory will provide a source of funding for the continued operation , maintenance, and servicing of the landscaping and appurtenant facilities (collectively referred to as improvements) to be provided by the District for the special benefit of properties within the Tract.

The District assessments as described herein are based on the City’s estimate of the costs to maintain, operate and service the improvements. The costs of the improvements and the proposed annual assessments budgeted and assessed against properties within the Annexation Territory may include, but are not limited to the estimated expenditures for regular annual maintenance and repairs; incidental expenditures related to the operation and administration of the District; deficits or surpluses from prior years; revenues from other sources; and the collection of funds for operational reserves and/or periodic repairs, replacements and rehabilitation projects as authorized by the 1972 Act. The net annual cost to provide the improvements for each Tract are allocated to the benefiting properties within that Tract using a weighted method of apportionment (refer to Assessment Methodology in Section II, Method of Apportionment) that calculates the proportional special benefit and assessment for each parcel as compared to other properties that benefit from the District improvements and services. Thus, e ach parcel is assessed proportion ately for only those improvements, services, and expenses for which the parcel will receive special benefit.

Ballot Proceedings
As part of these proceedings, the City shall conduct a property owner protest ballot proceeding (“Ballot Proceeding”) for the proposed levy of an assessment pursuant to the provisions of the California Constitution, Article XIIID Section 4 , and in accordance with the provisions of Government Code, Section 53753 . In conjunction with this Ballot Proceeding, the City Council will conduct a noticed public hearing to consider public testimonies, comments and written protests regarding the annexation, and the assessments described herein. Upon conclusion of the public hearing, property owner protest ballots received will be opened and tabulated to determine whether majority protest exists as defined in Article XIIID of the California Constitution.

As specified by the California Constitution, Article XIIID Section 4e:
“A majority protest exists if, upon the conclusion of the hearing, ballots submitted in opposition to the assessment exceed the ballots submitted in favor of the assessment. In tabulating the ballots, the ballots shall be weighted according to the proportional financial obligation of the affected property.” After completion of the ballot tabulation, the City Council will confirm the results of the balloting. If majority protest exists for the proposed Tract No. 20275 assessments, further proceedings to annex the parcels within the District and implementation of the Tract and assessments shall be abandoned.

If tabulation of the ballots indicate that majority protest does not exist for the proposed assessments and the assessment range formu la presented and described herein, the City Council by resolution may adopt this Report (as submitted or amended); approve the assessment diagrams (Tract Boundary Diagram) contained 1338

The assessments as approved, may be levied and collected on the County tax rolls commencing in Fiscal Year 2023/2024 and may be handbilled in Fiscal Year 2022/2023 . For Fiscal Year 2023/2024 and each subsequent fiscal year, this tract will be included in the Annual Consolidated Drainage Facilities Assessment District Report, which shall be prepared and presented to the City Council to address any proposed changes, including Tract No. 20275, as well as any proposed changes to the improvements, budgets, and assessments for that fiscal year. The City Council shall hold a noticed publi c hearing regarding these matters prior to approving and ordering the levy of annual assessments for the District.

If in any fiscal year, the proposed annual assessments for parcels with the District exceed the maximum assessments described herein, such a n assessment would be considered an increased assessment and must be confirmed through a mailed property owner protest ballot proceeding for the affected parcels before the increased assessment may be imposed.
