Decoherence and relaxation of solid-state defect qutrits near a crystalsurface, where they are commonly used as quantum sensors, originates fromcharge and magnetic field noise. A complete theory requires a formalism fordecoherence and relaxation that includes all Hamiltonian terms allowed by thedefect's point-group symmetry. This formalism, presented here for the $C_{3v}$symmetry of a spin-1 defect in a diamond, silicon cardide, or similar host,relies on a Lindblad dynamical equation and clarifies the relativecontributions of charge and spin noise to relaxation and decoherence, alongwith their dependence on the defect spin's depth and resonant frequencies. Thecalculations agree with the experimental measurements of Sangtawesin$\textit{et al.}$, Phys. Rev. X $\textbf{9}$, 031052 (2019) and point to anunexpected importance of charge noise.
